Abstract
Description
- The present invention relates to an improved reclosable, tamper-evident container formed, at least in part, from a flexible material. Access to the interior of such a container is provided by a security seal formed through the flexible material, and the reclosable fastener of this invention is attached to the container in sealing relation to that seal. The improved fastener of this invention is particularly characterized by its structure comprising a pair of mating, reclosable sealing strips, both of which are attached to a common surface of the container's flexible material. Preferably, the reclosable fastener of this invention is disposed on the inside surface of the container.
- Reclosable containers utilizing zipper-type fasteners are well known in the packaging industry and are used for holding, displaying and dispensing a wide variety of products ranging from hardware items to food products intended for human consumption. The construction of virtually all such prior art fasteners comprises one or more female parts which releasably receive one or more corresponding male parts. In order to provide access to the interior of the container, those portions of the fastener bearing the respective female and male parts must typically be attached to opposing sides of the container such that the female and male parts will be in registry with each other. A typical such construction is disclosed in U. S. Patent No. 4,909,017 to McMahon and Spanier.
- Obviously, then, according to the present state of the packaging arts, great care and precision are required in the placement and attachment of reclosable fasteners to their related containers. Notwithstanding the existence of a great variety of such fasteners and reclosable containers utilizing such fasteners, it is clear that there remains a great need in the packaging arts for a reclosable, zipper-type fastener, both parts of which can be attached to a single common surface of the material forming a wall of the container before the container is even partially formed. Such a fastener would significantly simplify the manufacturing process for reclosable containers by not interfering with the operation of standard forming and filling machines.
- The present invention relates to an improved tamper-evident container formed from a flexible material and having a reclosable fastener. In a preferred embodiment, the fastener of this invention comprises a pair of mating, reclosable sealing strips, each comprising a strip base segment which is attachable to a common surface of the material forming a wall of a reclosable container. Each of the sealing strips further comprise a second segment integral with its corresponding base segment and free from the container wall surface. One of the strips comprises a male fastener part, and the other of the strips comprises a female fastener part in receiving relation to the male part. Tamper-evident access to the interior of the container is provided by a removable portion of the flexible material to form an aperture for access to the reclosable fastener.
- According to a first embodiment of the reclosable fastener, the male fastener part is at the juncture of one of the base segments and its corresponding second segment, and the female fastener part is formed on the second segment of the other sealing strip. Both base segments are attached to a common interior surface of the flexible material, and both second segments are free from the common surface.
- According to a second embodiment, the female fastener part is formed on one of the sealing strip second segments, and that second segment is attached to a second surface of the flexible material opposite the common surface.
- Also disclosed and claimed hereinafter is a method for attaching the reclosable zipper-type fastener to the flexible material from which the container is made so as to provide a tamper-evident reclosable seal.
- The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts which will be exemplified in the constructions hereinafter set forth, and the scope of the invention will be indicated in the claims.
- For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:
- FIGURE 1 is a side elevation showing a segment of a first embodiment of the container of this invention with the fastener attached to the inside of a segment of the flexible material at least partially forming a reclosable container.
- FIGURE 2 is a side elevation similar to that of Fig. 1 showing the segment of the reclosable container with the tamper-evident portion removed and the fastener opened.
- FIGURE 3 is a view similar to that of Fig. 1 showing a second embodiment of the container.
- FIGURE 4 is a side elevation similar to that of Fig. 3 showing the segment of the reclosable container with the tamper-evident portion removed and the fastener opened.
- FIGURE 5 is a sectional view taken along line 5-5 of Fig. 6 showing attachment of the reclosable fastener to a common interior surface of a reclosable container.
- FIGURE 6 is a plan view of the reclosable container shown in Fig. 5.
-
- Similar reference characters refer to similar parts throughout the several views of the drawings.
- A first embodiment of the improved tamper-evident container formed from a flexible material and having a reclosable fastener is generally indicated as 10 in the views of Figs. 1, 2, 5 and 6. The reclosable fastener is generally indicated as 12.
- Referring to the view of Fig. 1, it can be seen that
fastener 12 comprises a pair of mating, reclosable sealing strips, generally indicated as 14 and 16, respectively. Each of thesealing strips base segment Base segment 18 is attached tointerior surface 22 offlexible material 24, andbase segment 20 is similarly attached to thecommon interior surface 22. As shown in Fig. 1, attachment of thefastener 12 to commoninterior surface 22 is indicated byperimeter seal 26. - Also shown in the view of Fig. 1 is a
removable portion 28 offlexible material 24 by which access to the interior ofcontainer 10 may be obtained onceportion 28 is removed to form an aperture providing access tostrips removable portion 28 is defined by a plurality of cuts formed throughflexible material 24. In the preferred embodiment, these cuts comprise a plurality ofperforations 30 and at least oneslit 32, though a pair ofopposed slits 32 are illustrated in the view of Fig. 6.Slit 32 provides a free segment offlexible material 24 wherebyportion 28 may be removed to provide access tofastener 12. Theperforations 30 are preferably formed within the area defined by line A-A, and the slit, or slits, 32 are preferably formed within the area between arrows B. - Returning to the view of Fig. 1,
sealing strip 14 further comprises asecond segment 34 integrally formed therewith, but not attached to commoninterior surface 22.Sealing strip 16 also comprises-asecond segment 36 integral with itsbase segment 20, but not attached to commoninterior surface 22. Afemale fastener part 38 is formed onsecond segment 34, and a correspondingmale fastener part 40 is formed onsealing strip 16 at the juncture ofbase segment 20 withsecond segment 36. - As further shown in the view of Fig. 1,
container 10 further includes another segment of flexible material 24' forming another wall thereof, and aseam 42 is provided by the joining offlexible material 24 to a corresponding segment of flexible material 24'. Referring to the views of Figs. 5 and 6, a similar seam 42' is formed at the bottom ofcontainer 10. - Referring to the view of Fig. 6, and remembering that a principal end use for the
container 10 is to hold food products intended for human consumption, the formation of an hermetic seal is a particular advantage of this invention. As shown in Fig. 6, theperimeter seal 26 extends around the perimeter offastener 12. However, a broadenedsegment 44 can be seen at each end ofperimeter seal 26. Broadenedsegment 44 is frequently referred to in the packaging industry as a "splotch" seal. Such a splotch seal involves the application of heat and pressure to the distal ends ofsealing strips segment 44. Then, when thefastener 12 is attached to commoninterior surface 22 offlexible material 24 by theperimeter seal 26, an hermetic seal is formed in completely surrounding relation to theremovable portion 28. - Referring now to the views of Figs. 3 and 4, a second embodiment of the tamper-evident container is generally indicated as 10'. Inasmuch as the structural elements of container 10' are essentially identical to those of
first embodiment 10, identical reference numerals have been used for their identification. As clearly shown in the views of Figs. 3 and 4, second embodiment 10' further comprises atack seal 46 to bondsecond segment 34 to insidesurface 48 of flexible material 24' forming the opposite side of container 10'. Such a construction virtually eliminates any probability of material contained within container 10' becoming wedged or caught in the gap otherwise present betweensecond segment 34 and flexible material 24'. - From the above description of the structure of first and second embodiments of the
container 10 and 10', respectively, attention is now invited to the following description of the method for attachingfastener 12 to aflexible material 24 for providing a tamper-evident reclosable opening therethrough. First, a segment offlexible material 24 is selected for forming acontainer 10. A plurality ofcuts comprising perforations 30 and at least oneslit 32 are made to define aremovable portion 28. Next, a reclosable zipper-type fastener 12 is selected and cut to a predetermined length sufficient to overlie theremovable portion 28. Opposed distal ends offastener 12 are then "splotched" and the splotched length of fastener is disposed in adjacent, overlying relation toremovable portion 28. Theperimeter seal 26 is formed by the application of pressure and heat. If desired,tack seal 46 would be made in a subsequent step. From that point on, the container would be formed and filled using standard form and fill apparatus and methods. No further manipulation offastener 12 and its relatedremovable portion 28 is required. - It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efficiently attained, and, since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
- It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
- Now that the invention has been described,
