Description

The invention relates to a packaging container made of a cup-shaped plastic part, as described in the preamble of claim 1.

From the US 2001/0033882 A1 a packaging container has become known from a cup-shaped plastic part, which comprises a jacket and a bottom. In the transition region between the bottom and the shell, a circumferential, tubular standing edge is arranged, which delimits a recessed in the direction of the central axis receiving space. This receiving space is used to hold utensils and is covered by a planar closure element at the bottom of the tubular edge of the stand. This planar covering element is kept detachable via retaining lugs from the lower edge of the tubular standing edge.

From the DE 202 08 068 U1 For example, a food packaging and feeding bowl with at least one food utensil has become known. In the bottom area elevations are formed, between which the food utensil is located. At the outer ends of one or all elevations are adhesive surfaces, wherein the at least one eating utensil is enclosed with a cover attached to the surveys. The cover has at least one tab, with which it can be detached from the packaging or feeding bowl and thus the access to the food utensil is released.

From the WO 02/12078 A1 a receptacle has become known in which in the region of the bottom in the container casing an additional receiving chamber separate from the receiving chamber is arranged, in which different products formed to the filling material to be received. To limit the additional receiving chamber and thus to prevent inadvertent loss or removal of these objects from this chamber, a cover is provided which covers a portion of the chamber. This partial covering of the chamber can be achieved by means of a pivotable angular element, an insertable and latchable L-shaped element ( Fig. 3d ) or a jacket-shaped element enclosing the container jacket at least partially enveloping.

The JP 2002 045 046 A describes one or more seed pots for young plants which is formed in the region of the upper edge of the container a Einsteckschlitz for a marking strip. In the vicinity of the Einsteckschlitzes the container wall is set back in the direction of the receiving space of the plant pot to separate that portion of the identification strip which extends through the slot from the receiving space for the young plant. This avoids direct contact of the identification strip with the soil surrounding the young plant and thus creates an area for arranging the insertion slot in the region of the open end of the plant pot. The identification strip has corresponding latching projections in order to hold these in the slot. Another section of the identification strip protrudes beyond the open end of the pot in the side facing away from the ground and is thus easy to see without any manipulation of the pot.

From the WO 98/13270 A1 a combination packaging container known which comprises an inner cup-shaped plastic inner part and a pushed over the plastic inner part and the plastic inner part outside surrounding shell-like outer part. The plastic inner part has in the region of its container shell an inwardly recessed form for receiving additional objects between the plastic inner part and the outer part pushed over the order to remove the recorded in the recessed form additional object is at the upper edge and / or lower edge of the jacket-shaped outer part an engagement opening released. The additional object is a consumption aid for the contents taken in the combination packaging container and may be formed by a drinking straw or a spoon.

The German utility model DE 81 07 433 U describes a packaging container from a cup-shaped plastic part with a thin-walled jacket. This cup-shaped plastic part is closed in its first end region by a bottom and has in its opposite second end region on a first opening which is closed by a closure element. On the bottom side, all wall sections of the oval-shaped cup pass over a curve into the likewise oval-shaped edge of the stand or floor.

The Patent Application JP 10 305861 A shows a cup-shaped packaging container having a convex curvature in the transition region from the jacket into the ground, wherein additionally a stand edge for the cup-shaped plastic part is still arranged in the bottom area.

The Patent Application JP 10 324369 A merely describes a receptacle formed elliptical in cross-section, wherein on diametrically opposite sides of the container projections are formed, with which the cup for the opening process can be biased or compressed by the closure element and thus spilling or scattering of the stored medium in the interior is prevented ,

From the DE 298 19 987 U1 , of the DE 1 030 209 B , the DE 43 pos 925 A1 as well as the US 2002/0093189 A1 are each different arrangement options of information carriers with an identification feature known, which are each arranged in the jacket region of the container.

The production of cup-shaped packaging containers made of plastic for receiving dairy products has long been known. Here, plastic cups are deep-drawn with a more or less downwardly tapering body or produced by similar methods. The resulting cup shape is on both the outside and on the inside strictly conical with mostly sharp-edged transitions to a cylindrical or konterkonischen training in the upper, near the opening area and sharp or formed by small radii transitions from the conical region to the bottom region.

Due to these sharp-edged or small-radius transitions or edges, the removal of the contents, which preferably takes place by means of spoons or spoon-like objects, is made more difficult in these areas, especially during the transition from the bottom to the conical jacket and in the transition to the counter-conical part.

The invention has for its object to provide a structurally reinforced packaging container, which allows for improved identification.

The object is achieved in that the label is formed by a planar information carrier with an identification feature, and a transition region of the jacket in the ground formed footprint in a plane passing through the central longitudinal axis of the packaging container has a convex curvature with respect to the outer surface of the cladding or bottom, the transition region being formed as a reinforcing region, the reinforcing region surrounding the label carrying information carrier; a wall thickness in the region of the shell between 10% and 40%, in particular between 15% and 30%, a wall thickness in the region of the gain range, wherein in the vertical direction with respect to the central longitudinal axis, a difference in radius between a maximum radius of the gain region and a radius of the directly adjacent Mantelbereiches between 0.4% and 10% of a closure element radius.

It is advantageous that when using a code this can be used to identify the packaging container in terms of its origin, date of manufacture, date of fomentation, content, price, durability, etc. If the receiving space for receiving accessories, such as gift items, toys for children, recipes, cards for raffles, scratch cards or items that serve to remove the contents of the packaging container formed, they are visible, for example, by upside down the packaging container or removable , At the same time, the information carrier also prevents the accessory from falling out. If such packaging containers are stacked in the empty state for the purpose of transportation, damage can be reduced in the area of the first end region closed by the bottom due to the high weight caused by the stacking and more containers can be stacked without damage due to the higher strength. Due to the difference in radius between the reinforcing region and the adjacent jacket region, transitions in the radius of the packaging container can be rounded, as a result of which no or only little residual material can catch at these transitions and thus easier removal is possible.

An arrangement of a second opening or a weakening area formed in the region of the bottom for producing a second opening is advantageous since it makes it possible, according to the invention, on the one hand to provide a further access area to the contents of the container, and on the other hand to specify further embodiments of the packaging container which facilitate the removal or access to the content, such as thereby also the possibility is created behind the opening or for the formation of the opening formed To dispose of weakening an additional receiving space and thus to provide the opportunity to easily remove a content contained therein or pack this content separately from the rest of the content.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

Fig. 1 shows a first embodiment of a packaging container. 1

Shown is a packaging container 1 with a jacket 2 formed by a hollow truncated cone, which is closed by a bottom 4 in the region of a first end region 3 and has a first opening 6 with a closure element 7 in the opposite second end region 5.

In the region of the first end region 3, a reinforcing region 8 extending over the circumference of the packaging container 1 can be arranged, which forms a transition between the jacket 2 and the bottom 4 of the packaging container 1. The reinforcing portion 8 has a convex curvature 9 with respect to the outer surface of the skirt 2 or the bottom 4. The shape of the curvature 9 can, as in Fig. 1 illustrated, formed However, may also have the shape of a quarter circle, ie the curvature runs on the side of the reinforcing region 8 which is the jacket 2, adjacent, approximately parallel to a central longitudinal axis 10 of the packaging container 1 and can at the bottom 4 closer side of the Reinforcement area 8 almost in the vertical direction to the central longitudinal axis 10 extend. The advantage here is that the footprint of the packaging container 1, while maintaining high strength, is maintained.

Between these two regions, the curvature 9 can have approximately a radius of curvature 11 or a radius of an enveloping circle which is greater than 4 mm, preferably greater than 6 mm, in particular greater than 8 mm. According to the invention, it is also possible that the curvature 9 has any other shape of a convex curvature, for example in the region of the reinforcing region 8 which is adjacent to the jacket, does not run parallel to the central longitudinal axis 10, but substantially in the direction towards the first opening 6 conically expanded.

Of course, the curvature 9 can also be composed of a plurality of "partial curvatures" such that curvatures of different radii of curvature 11 adjoin one another and thus obtain an optimum shape for the respective application.

If the closure element 7 is formed by a circumferential, planar sealing flange, it becomes possible, according to the methods known from the prior art, to close the packaging container with a sealing film, preferably a metal foil. By a corresponding design of the closure element 7, for example by a circumferential curved flange or a circumferential bead, it is further possible to have elastically deformable lid, for example made of plastic, snap fit over the closure member 7 so as to provide a resealable packaging container 1.

Such packaging containers 1 are often stacked in the empty state for the purpose of transport. In the case of embodiments which are known from the prior art, damage may be caused in the region of the first end region 3, due to the high weight caused by the stacking or due to the relatively sharp curves and edges, or may result in buckling and deformation of the packaging container 1 come. Due to the inventive design of the packaging container 1, such damage is reduced and more containers can be stacked without damage due to the higher strength.

The arrangement of the reinforcing region 8 further facilitates access to the contents or the removal of the contents of the packaging container 1. Since the radius of curvature 11 in the known from the prior art packaging container 1 or cups very small or the transition from the shell area in the bottom area is very sharp, a complete or nearly complete removal of the contents was difficult to perform and a tedious "scraping "with a spoon, for example. The inventive design, the removal of the content can be substantially facilitated if the curvature 9 or at least parts of the curvature 9 is adapted to that of a conventional spoon, in particular teaspoon.

It also proves to be advantageous if the radius of curvature 11 or the radius of an enveloping circle is greater than 6 mm, in particular greater than 8 mm. This ensures that, if larger spoons are used than, for example, common teaspoons, it is easy to remove the goods or the residual material.

Furthermore, this embodiment leads to an increase in strength or stiffening in these areas, as a result of which the handling, especially during filling or later use, becomes more secure and buckling during stacking is also prevented.

The jacket 2 can also be provided between the first end portion 3 and the second end portion 5 at least partially by grooves or ribs in the direction of the central longitudinal axis 10, which are distributed along the circumference, which have the advantage of additional reinforcement and better orientation or Fixing the situation when stacking the packaging container 1 offers (in Fig. 1 not shown).

Fig. 2 shows a further embodiment of a packaging container 1, with a arranged in the second end region 5 gain region. 8

The reinforcement region 8 can be arranged either alone or in combination with further reinforcement regions.

According to the invention, the radial difference 12 between the largest radius 51 of the reinforcement region 8 and the radius 52 of the jacket region directly adjacent thereto is between 0.4% and 10% of the closure element radius 13. The radii 51, 52, the closure element radius 13 and the radial differences 12 are understood measured perpendicular to the central longitudinal axis 10. According to the invention, it is also possible for this radius difference 12 to be between 0.8% and 6% of the closure element radius 13. As a result, transitions in the radius of the packaging container 1 can be rounded, whereby no or only a little residual material can catch at these transitions and thus easier removal is possible.

In this case, according to the invention, the largest radius 51 of the reinforcement region 8 may be larger than the radius 52 of the directly adjacent jacket region 2. According to one embodiment, however, it is also possible, especially when the jacket 2 is formed approximately cylindrically or counter-conically in the second end region 5, that the largest radius 51 of the reinforcing region 8 is smaller than the radius 52 of the directly adjacent jacket region 2. This results in the transition of the arranged in the second end region 5 shell 2 softens the conical jacket and prevents or reduces a catch of residual and thus facilitates the removal of the contents.

In addition, by means of the reinforcing region 8 arranged in the second end region 5, a structural reinforcement of the packaging container 1 or a deformation during the lifting of the container by a user is reduced.

The packaging container 1 has, in the first end region 3, the reinforcement region 8 with a curvature 9. This curvature 9 of the reinforcing region 8 has a radius of curvature 11 with respect to a cutting plane contained in the central longitudinal axis 10, which radius of curvature may be different at different points in the curvature 9. As already stated, the curvature 9 can take on any convex shape, such as the shape of a quarter circle. However, the curvature 9 can also have other convex curvature forms and, for example, be formed by an elliptical section. Is advantageous In particular, when tangents at surface points of an inner side 53 of the packaging container 1 show a steady, non-erratic course of their inclination in the transition from the bottom 4 into the reinforcement region 8 or from the reinforcement region 8 into the shell 2. In the transition regions between the bottom 4 and the reinforcing region 8 or between the reinforcing region 8 and the sheath 2 no edges or pointed throats are present on the inside 53 in this case.

According to the invention, the wall thickness 54 of the packaging container 1 in the area of the jacket 2 is between 10% and 40%, in particular between 15% and 30%, of the wall thickness 55 in the region of the reinforcement area 8 (in FIG Fig. 2 indicated by the hatched area). This offers the advantage of a material saving and thus lower production costs. The necessary structural strength is nevertheless given since an increase in the strength is achieved on account of the reinforcement regions 8 or closing element 7 arranged in the first end region 3 or in the second end region 5.

According to the invention, the packaging container 1 can be formed from a plastic film, in particular by a deep drawing process. The production or molding by injection molding or injection blow molding or blow-stretch blow molding, however, is also possible.

The material for forming the plastic film may be selected from the group of polypropylene, polystyrene or polyesters. As a result, the raw material costs can be kept low and allows the use of these materials in addition to food authenticity, a relatively uncomplicated processing.

Polypropylene packaging containers have good strength and rigidity at low density, while having good stress cracking resistance. They retain their properties even at higher temperatures, whereby a packaging of warm material or heating of the content in the packaging container 1 according to the invention is possible.

Polystyrene in its basic form is clear-sighted with high rigidity and hardness. However, it is also possible according to the invention to color the material to the appearance of the packaging container to adapt to the respective requirements. Due to the high strength, the use of these materials makes it possible to reduce the wall thicknesses of the packaging container to a minimum, which not only reduces costs but also reduces weight and thus brings advantages, inter alia, during transport of the containers.

Fig. 3 shows a further packaging container 1 with an additional, arranged in the region of the jacket 2 weakening region 16 and a second opening 15th

It should be noted at this point that individual components of the individual variants are transferable to the other alternative embodiments, e.g. the arrangement of reinforcing regions 8 or the arrangement or formation of openings on the packaging container 1 or training with rectangular or triangular cross-section or cylindrical or counter-conical shapes, so that these parts of description are transferable accordingly, even if not explicitly taken in the individual embodiments thereof reference ,

According to the invention, it is possible for a second opening 15 or a first weakened area 16 designed to produce a second opening 15 to be arranged in the region of the jacket 2 of the packaging container 1. By such a configuration, it is possible according to the invention not only to gain access to the contents of the packaging container 1 through a first opening 6, but also, if necessary, to remove the contents through this second opening 15. The production of the second opening 15 can already take place during the actual forming process of the packaging container 1, for example by arranging gaps in the mold. Also, subsequent punching a second opening 15 is possible, which is advantageous in more complicated forms of the second opening 15.

For example, to prevent the unwanted falling out of the content or the view of the content, it is possible according to the invention to form the second opening 15 initially closed. This can be done for example by a seal with a foil or a punch along a line of weakness in the weakened region 16. If necessary, access to the content can be released by tearing open or tearing off a first weakened area 16.

According to the invention, the second opening 15 or the weakening area 16 forming this opening can extend between the reinforcing area 8 arranged in the first end area 3 and the reinforcing area 8 arranged in the second end area 5. Furthermore, the extent of the second opening 15 or the weakening region 16 in the circumferential direction can be up to 120 according to the invention. As a result, it is advantageously possible to optimally adapt the second opening 15 or the weakened area 16 to the respective content of the packaging container 1. Also, the shape of the second opening 15 and the weakening area 16 is not on the Fig. 3 Rectangular shape shown to be limited, but are erfindungemäß, as shown in the 4 and 5 is shown, even circular or oval shapes or polygons as training the second opening 15 possible. Also encompassed by the invention are complex shapes, such as the silhouette of objects or figures, in particular comic figures.

Fig. 6 shows a packaging container 1 in a view along the central longitudinal axis 10 in a circular configuration. The bottom 4 or its contour in the region of the first end region 3 is not shown.

Shown is a receiving space 17 recessed in the region of the second opening 15 in the direction of the central longitudinal axis 10 of the packaging container 1.

The receiving space 17 can be mitgeformt already during the manufacture of the packaging container 1, but can also be formed, for example, for more complex forms of the receiving space 17 by prefabricated moldings and subsequently connected to the packaging container 1, for example, welded or glued, be. Since the receiving space 17 is only connected to the packaging container 1 immediately before filling, a high stack density is achieved, as a result of which high transport quantities and thus lower costs are achieved as a consequence.

Due to the design of the packaging container 1 with a receiving space 17, it is possible to integrate an additional content to be packaged separately from the remaining contents of the packaging container 1. The size of the receiving space 17 corresponds to the size of the second opening 15 and the first weakening region 16 (in Fig. 6 not shown). It is preferably provided that the recessed receiving space 17 at the second opening 15 or the first weakening region 16 adjacent. The shape of the receiving space 17 itself is in Fig. 6 shown as an example only approximately rectangular. However, it is inventively possible to form the receiving space 17 in any desired, adapted to the application form.

The outer contour of the packaging container 1 along the central longitudinal axis 10 may be both cylindrical and conically tapered or widening.

Fig. 7 shows a packaging container 1 in a view along the central longitudinal axis 10 in a rectangular configuration.

In this embodiment, the contour of the shell 2 of the packaging container 1 is designed rectangular. The predominantly rectangular receiving space 17 is arranged in one of the corners of the packaging container 1. Access to the receiving space via the second opening 15. The corners of the packaging container 1 and the receiving space 17 can also be rounded according to the invention. Likewise, the cross sections of the packaging container 1 and the receiving space 17 may be square.

The receiving space 17 extends along the central longitudinal axis 10 between the reinforcement region 8 arranged in the first end region 3 and the reinforcement region 8 arranged in the second end region 5 (in FIG Fig. 7 not visible). In this case, the receiving space 17 can be arranged both in the lower, first end region 3 and in the upper, second end region 5. Preferably, the receiving space 17 in the region of the jacket 2 in an area with the thinner than the wall thickness 55 wall thickness 54 (see Fig. 2 ) arranged.

The outer contour of the packaging container 1 along the central longitudinal axis 10 may be both rectangular or square and conically tapered or widening. That the jacket 2 of the packaging container 1 is preferably conical, with the jacket 2 facing upwards, i. in the direction of the first opening 6, expanded.

Other possible embodiments of the outer contours of the packaging container 1 show FIGS. 8 and 9 ,

In Fig. 8 the packaging container 1 is approximately elliptical or oval.

If the shape of the packaging container 1 is further formed in the direction of a narrow ellipse (boat shape), this has the advantage that this shape of the human hand when gripping and holding the container is even better ergonomically adapted and thus a secure hold at the same time pleasant feeling is given.

The receiving space 17 may be arranged, for example, on the longitudinal side and formed in cross section in the form of a half ellipse.

Fig. 9 shows a packaging container 1 in a triangular configuration.

The semicircular receiving space 17 is located on one of the sides of the triangle.

An advantage of this embodiment is a simplified emptying process through the formation of a "gutter" through the acute angle of two adjacent triangular sides of the packaging container 1.

Fig. 10 shows a packaging container 1, in perspective view.

Shown is in the region of the bottom 4 a set back in the direction of the central longitudinal axis 10 of the packaging container 1, adjacent to the second opening 15 receiving space 17. However, it is also possible that in the region of the bottom 4 a weakening area is arranged, the access after removal to the receiving space 17 allows. In the receiving space 17 erfindungemäß an identification feature, in particular a label with attached thereto barcode or similar codes arranged.

Furthermore, it is also possible to attach the barcode, for example, directly to a wall bounding the receiving space 17, for example by means of an offset printing process or by embossing or depressions in the container wall itself. In the case of attaching a label, it is possible by this example a hot pressing process or by means of an ultrasonic welding process or various, suitable for secure adhesion adhesives or adhesives to the packaging container 1 to fix. The inventive attachment of the label is defined in claim 1.

In the region of the first end region 3 and / or in the region of the second end region 5, one or more reinforcement regions 8 can be arranged. The shoulders of the reinforcing regions 8 form coupling elements 14 for fixing a jacket-like outer part 18. The outer part 18 is wrapped around the jacket 2 of the packaging container 1 in the form of a sleeve or sleeve. The outer part 18 may e.g. be made of a cardboard strip.

Further shows Fig. 10 a shell-like outer part 18 surrounding the packaging container 1 and located between the region of the reinforcing region 8 in the region of the first end region 3 and the region of the reinforcing region 8 in the region of the second end region 5.

The shell-like outer part 18 assumes the function of a support jacket and gives the packaging container in the region of the shell 2 a high stability.

According to one embodiment of the invention, a further opening 19 or a further weakening area 20 designed to produce a further opening 19 can be arranged in the shell-like outer part 18. The further opening 19 may be reclosable. This can be done for example by a protruding tab 21 which can be clamped between the shell-like outer part 18 and the jacket 2 of the packaging container 1. It is also possible a glue point at the location of the outer shell-like part which is covered by the tab 21.

Furthermore, behind the region of the further weakened region 20 or behind the further opening 19, a receiving space 17 with a second opening 15 can be arranged (in FIG Fig. 10 not shown, see Fig.6 - 9 ). The further opening 19 can according to the invention have the same size as the underlying second opening 15, which allows access to the receiving space 17. It is also possible that the receiving space 17 is formed by corresponding wall parts of the shell-like outer part 18. In the design the shell-like outer part 18 of a plastic material, for example in the form of a little bag, the advantage of a cost-effective manufacturing process is achieved because, for example, an additional content is integrated in the bag of the shell-like outer part 18, the bag, for example, sealed with a seal, and the coat-like outer part 18 is arranged around the packaging container 1, that the bag is arranged in or behind the second opening 15.

The shell-like outer part 18 may be formed according to the invention by a cardboard material. By forming fixing or coupling elements 14 through the reinforcement region 8 in the region of the first end region 3 and the reinforcement region 8 in the region of the second end region 5, it is possible according to the invention to fix the jacket-like outer part 18 to the packaging container 1. Special advantages of the shell-like outer part 18 when no adhesive or the like must be used by the coupling elements 14, since it is rotatable about the central longitudinal axis 10 of the packaging container 1 and can form a resealable closure element 7 for a receiving space 17. This is advantageous if a tamper-evident closure, for example a sealing foil, fitted over the receiving space 17 has already been removed after first use since a simple re-closing by rotating the jacket-like outer part 18 is thus possible.

By rotating the shell-like outer part 18, furthermore, the entire information or images, for example instructions for use, arranged over the circumference of the packaging container 1 can be made visible. The shape of the further opening 19 is not according to the invention on the Fig. 10 shown limited form. For example, rectangular or more complex geometric shapes or silhouettes of figures, in particular comic figures, may be formed. Furthermore, it is possible for the further weakening region 20 to form separable elements, which form, for example, elements of a puzzle.

According to the invention, the reinforcing regions 8 need not be restricted to the region of the first end region 3 or of the second end region 5, but a plurality of reinforcing regions 8 can be distributed over the entire jacket 2 of the packaging container 1. Accordingly, a plurality of shell-like outer parts 18 may be arranged between the respective reinforcing regions 8. It is also possible for the closure element 7, in particular a sealing flange, to form the coupling element 14.

According to the invention, it is possible that the packaging container 1 is printed directly in the region of the jacket 2, for example with an offset printing method, whereby it is possible to make this information or images visible through the further opening 19.

The height of the further weakening region 20 or the further opening 19 can extend to up to 95% of the jacket-like outer part 18, whereas the width of the further opening 19 or of the further weakened region 20 can extend up to 50% of the circumference.

It is also possible that the shell-like outer part 18 consists of a plastic material, wherein the fixing of this outer part in the region of the first end portion 3 by a arranged in this area reinforcing region 8 or by the closure member 7 can take place or a plastic hose over the desired area of the packaging container 1 is pushed and eg can be shrunk under heat.

As a material for the shell-like outer part 18, as already stated, cardboard but also plastic can be used. In particular, it is also possible to use a composite material which is composed of several layers of different materials, such as cardboard, plastic, but also metal foils. In the case of using a cardboard material is provided to provide the corresponding outer part 18 with a water-repellent layer. This can e.g. by using a laminated with a plastic film cardboard strip, which is tailored to take place. It can also be provided in particular that the cardboard is additionally sealed in the region of the cut edges with a water-repellent material. This is particularly advantageous when the packaging container 1 are exposed to increased moisture access. The coating of the cardboard used for the outer part 18 with a water-repellent layer is namely prevented that one of the moist environment to swelling of the carton and finally comes to a detachment from the jacket 2 of the packaging container 1.

Furthermore, it is possible to arrange another shell-like outer part between the shell 2 of the packaging container 1 and the shell-like outer part 18, so by turning the shell-like outer part 18 and thus the further opening 19 and the other Weakening range 20, the other jacket-like outer part or its printing is visible.

Due to the fact that a plurality of reinforcing regions 8 can be arranged distributed over the height of the packaging container 1, it is also possible to arrange a plurality of jacket-like outer parts 18 and also several further jacket-like outer parts with different colors or imprints and several openings or areas of weakness associated with each of these areas.

The holder of the shell-like outer part 18 is effected by the coupling elements 14 positively and releasably. The further shell-like outer part can according to the invention be permanently attached, in particular by an adhesive, to the shell 2 of the packaging container 1.

The conicity of the cup or the cone angle of the shell 2 may be greater than 4 °, in particular greater than 5.5 °, but may in particular in the second end portion 5 cylindrical or slightly konterkonisch, since thereby the manufacturing or filling process by an improved handling or recording in the filling station is simplified.

Fig. 11 shows a variant of the further opening 19 and the further weakening region 20, in a rectangular configuration.

The further opening 19 may extend over more than 50% of the height of the packaging container 1. It is again possible that a same size receiving space 17 is arranged for receiving an additional content. Otherwise, the under Fig. 10 Described.

Fig. 12 shows the further opening 19 in section XII-XII of Fig. 11 ,

It should be understood that the embodiment described herein can of course be applied to other forms of packaging container 1, for example of rectangular or triangular cross-section or cylindrical or conical shape.

Sheath 2 of packaging container 1 is shown in a section perpendicular to its central longitudinal axis 10. Sheath-like outer part 18 surrounds sheath 2 of packaging container 1. The further opening 19 is delimited by the further weakened area 20, wherein the further weakened area 20 is formed by, for example, a perforation may be and by severing the perforation, the further opening 19 is released. It is also possible that the perforation is interrupted at least over parts of the further weakened area, so that the further opening 19 remains after severing the remaining perforation on the jacket-like outer part and is thus reclosable. In order to fix the further opening 19 in the closed state, the tab 21 is arranged, which can be clamped, for example, between the jacket 2 and the jacket-like outer part 18.

The shell-like outer part 18 may be formed entirely from a cardboard material. However, it is also possible that the further opening 19 made of a plastic material, in particular of a transparent plastic material and the remaining part of the shell-like outer part 18 is formed from a cardboard material. The plastic material can be connected by, for example gluing or welding with the cardboard material.

The access to the packaging container 1 or to a receiving space 17 (in Fig. 12 not shown) takes place by means of the second opening 15 or by severing the first weakening region 16.

The weakened region 16 can be formed by a perforation along its weakening line or by a seal which is applied, for example, by an adhesive, in particular by a hot-melt adhesive.

Fig. 13 shows a variant of the reinforcing region 8 with arranged in the reinforcing region 8, radially extending grooves 22nd

These grooves 22 may be arranged distributed in uniform intervals over the circumference distributed in the gain region 8. They run radially with a depth or elevation of at least twice the wall thickness, preferably at least three times the wall thickness, is. According to the invention, the grooves 22 can also run only over partial regions of the reinforcement region 8. In addition, a further reinforcement region 8 may be arranged in the second end region.

The survey or the depression results in an additional stiffening of the gain region, whereby loads when stacking several packaging container 1 can be better absorbed.

The bottom 4 is rounded by a curvature 9 with raised central region such that the radius of curvature 11 is more than 4 mm, preferably more than 6 mm, in particular more than 8 mm.

This can on the one hand be prevented that can catch residual material in sharp corners or the removal of the contents can be simplified, on the other hand, a further reinforcing effect of the bottom 2 is achieved.

Of course, it is also possible to arrange a further reinforcement region 8 in the region of the second end region 5. The description of this and the other embodiments can be found in the corresponding parts of the further description of the figures.

Fig. 14 shows a variant of the packaging container 1 according to the invention.

Shown is a section through the first end portion 3 of the packaging container 1. In the bottom 4, a receiving space 17 is formed, which can receive an information carrier 23 in the form of a label with barcode applied thereto or similar codes. The code can be used to identify the packaging container 1 in terms of its origin, date of manufacture, date of filling, contents, price, shelf life, etc. The label is positively held by undercuts.

As in Fig. 14 is shown, in the region of the receiving space 17 also has a second opening 15, which is bounded by weakening areas 16 may be formed. Thus, it is possible to remove the contents of the packaging container 1 through the opening 15 after removal of the information carrier 23, which covers the receiving space 17. In addition, it can also be provided that this opening 15 is closed by a tamper-evident closure, such as a sealing foil, covering it.

Fig. 15 shows a further variant of the invention variant of the floor area.

Opposite the Fig. 14 is in Fig. 15 a larger receiving space 17 shown. The receiving space 17 can serve in addition to receiving the information carrier 23, for example, for receiving accessories 24, such as small gifts or toys for children or similar items. Also possible according to the invention are recipes, in particular preparation recipes, or also cards which are used for competitions, in particular scratch cards.

Also possible are contents that serve to remove the remaining contents of the packaging container, for example spoons, skewers or forks or similar objects.

According to the invention is also possible that the information carrier 23 is formed by, for example, a scratch card. At the same time, the information carrier 23 prevents the accessory 24 from falling out.

Of course, it is also possible to arrange a further reinforcement region 8 in the region of the second end region 5. The description of this and the other embodiments can be found in the corresponding parts of the further description of the figures.

Fig. 16 shows a further packaging container. 1

Shown is a packaging container 1 with parallel to the central longitudinal axis 10 extending coat 2. The first end portion 3 is closed with a bottom 4 and a reinforcing region 8 is formed, which forms a curvature 9, which has approximately a radius of curvature 11 and a radius of an enveloping circle, the greater than 4 mm, preferably greater than 6 mm, in particular greater than 8 mm.

In the region of the second end region 5, a further reinforcing region 8 is arranged. Fixing or coupling elements 14 for holding a jacket-like outer part 18 are formed by the reinforcing regions 8 in the region of the first and second end regions 3, 5.

The second end region 5 can be provided with a closure element 7, in particular a screw thread or a snap closure, with a closure element radius 13. As a result, a repeated removal or a safe resealing of the content is easily possible.

According to the invention, the closure element radius 13 may also be smaller than the radius in the jacket region, for example of the order of magnitude of commercial drinking bottles.

However, the closure element 7 can also be designed as a sealing flange, if a multiple closure of the packaging container is not required in a specific application.

In the region between the closure element 7 and the reinforcement region 8 in the region of the first end region 3, at least one second opening 15 can be arranged with a receiving space 17 recessed in the direction of the central longitudinal axis 10. The special form of the receiving space should not be on the in Fig. 16 be limited shown shape, but are also deviating from the rectangular shape forms possible, as has been described in the preceding figures.

Furthermore, it is possible in the region of the bottom 4 to arrange a second opening 15 with a recessed along the central longitudinal axis 10 receiving space 17, which may be closed for example by a peelable seal.

According to the invention, a jacket-like outer part 18 can also be arranged in the region of the jacket 2 of the packaging container 1, as a result of which an additional stiffening effect can be achieved. In addition, a further opening 19 or a further weakening area 20 may be arranged which allows access to the contents of the receiving space 17. The shell-like outer part 18 is fixed by the coupling elements 14 in the axial direction and can thus be rotated in the tangential direction.

The shell-like outer part 18 may further be provided with a tear strip, whereby it can be separated from the packaging container 1 and also an access to the contents of the receiving space 17 is made possible (in Fig. 16 not shown).

Based on Fig. 17 and 18 In the following, another embodiment of a packaging container 1 with a receiving space 17 will be described.

The Fig. 17 shows a packaging container 1 with a receiving space 17 in side view, shown partially in section. The receiving space 17 extends from a region of the shell 2 to the bottom 4 of the packaging container 1. With the exception of the area of the receiving space 17, the outer shape of the packaging container 1 is rotationally symmetrical. The receiving space 17 is closed by a cover 56. This cover 56 is shaped so that it is complementary to the other, with respect to the central longitudinal axis 10 rotationally symmetrical shape of the packaging container 1 is formed and in the patch, the receiving space 17 occluding state the packaging container 1 a total of a rotationally symmetrical shape. The shape of the receiving space 17 or the shape of a top wall 57 and a side wall 58 are designed so that a plurality of packaging container 1 can be nested without patch cover 56 and thus stacked. The transition region between the side wall 58 and the bottom 4 of the packaging container 1 is formed with a radius of curvature 59. Likewise, the transition region between the top wall 57 of the receiving space 17 and the jacket 2 is formed with a radius of curvature 60. Likewise, as already stated for the radius of curvature 11, it is also provided for these radii of curvature 59 and 60 that they are greater than 6 mm, in particular greater than 8 mm. As a result, as already with the radius of curvature 11, the advantage is achieved that in this area adhering content of the packaging container 1 with conventional spoons or a teaspoon can be easily removed.

However, the design of a stackable packaging container 1 having a cover 56 formed in the manner described above to be complementary to the outer shape of the packaging container 1 is not limited to a rotationally symmetrical outer shape but may be applied to packaging containers 1 having other cross sections.

The Fig. 18 shows a cross section of the packaging container 1 according to Fig. 17 , The recessed in the direction of the central longitudinal axis 10 of the packaging container 1 receiving space 17 is bounded on the one hand by a continuation of the jacket 2 formed from a part of the shell 2 side wall 58 and on the other hand by the cover 56. The transition regions between the center longitudinal axis 10 of the shell. 2 Concentric region and the side wall 58 are formed with a radius of curvature 61. Also for the values of the radii of curvature 61 apply the statements already made, as for the radii of curvature 11, 59 and 60. The connection of the cover 56 with the packaging container 1 can be done for example by gluing. But between the cover 56 and the jacket 2 of the packaging container 1 can also be formed, for example, a snap connection, so that the receiving space 17 can be reversibly opened and closed again. Due to the configuration of the packaging container 1 and the cover 56 according to this embodiment is achieved in an advantageous manner that the empty packaging container 1 can be nested or stacked and on the other hand is ensured by the formation of the cover 56 that the filled and sealed packaging container 1 via has sufficient stability.

The Fig. 19 shows a side view of a packaging container 1 with a rectangular cross-section. In the region of the jacket 2, the packaging container 1 has a second opening 15 and is fixed to the jacket 2 an outer part 18 extending between the first end region 3 and the second end region 5. The outer part 18 has in the region of the second opening 15 via a further opening 19. To close this further opening 19, a sliding closure 62 is provided, which can be reversibly pushed in front of the second opening 15 and removed therefrom. The representation according to Fig. 19 shows the sliding closure 62 in the open state. In order to operate the sliding closure 62, this also includes a tab 63rd

With respect to the outer shape of the rectangular packaging container 1 is provided that the jacket 2 widens upwards, ie in the direction of the first opening 6.

The packaging container 1 according to the invention and specified in claim 1 is provided, for example, for the ingestion of foods, such as milk products or the like. However, the use of the packaging container 1 is not limited thereto and is also possible for various other goods or goods to be packaged.

According to the invention, the packaging container 1 may be formed from a plastic film, in particular by a blow molding process. The production or molding by deep drawing or injection molding or injection-blow molding or injection-stretch blow molding is also possible.

The material for forming the plastic film may be selected from the group of polypropylene, polystyrene or polyesters, especially polyethylene terephthalate. As a result, good mechanical properties and food authenticity are achieved and allows the use of these materials a relatively uncomplicated or cost-effective processing. Both clear and colored materials can be used.

The shell-like outer part 18 may be formed from a cardboard material which is also colored or printed, but may be formed by a plastic film, in particular in the region of the height of the further opening 19 or the further weakened area 20 or in the area of a receiving space 17 located behind it ,

The exemplary embodiments show a variety of packaging containers, it being noted at this point that the invention is not limited to specifically illustrated embodiments, but at this point to the claims with regard to the scope of protection.

For the sake of order, it should finally be pointed out that for a better understanding of the structure of the packaging container 1, this or its components have been shown partially unevenly and / or enlarged and / or reduced in size.

The task underlying the independent inventive solutions can be taken from the description.
