In establish soft packaging bag and can close the Foldable package box of opening once more

The present invention relates to a fold-away shopping bag dress box that is used to pack drying, granular, pulverous or liquid product.This packing box has an inner soft packaging bag, and it makes that the product sealing of packaging is tight, and the opening on it can also be closed once more and be sealed.

French Patent (FRP) No.FR-A-2,071,733 has disclosed a card board package box that has an inner soft packaging bag.This packing box has a flap that forms opening on it.This flap is opened after when for the first time using this packing box, after opening flap, pull out inner soft packaging bag the formed opening one jiao, cut off this angle with scissors subsequently, the back also forms the opening that can therefrom pour out the packaging product on soft packaging bag.

Both inconvenience was not happy yet when therefrom pouring out the product of packaging for this interim repacking and the opening that forms, and opening closes once more also that envelope is not tight, so and unsatisfactory.

French Patent (FRP) No.FR-2,664,430 have disclosed one has an inner soft packaging bag and a folding packing box that can seal opening is once more arranged, on the wherein flap that can close thereon of the opening position of this box, the opening of inner soft packaging bag almost paste List on the opening that flap forms.

This folding packing box, form by one of them closed flap fully by thereon opening, so that the structure of this packing box is very complicated, and, for the opening with inner flexible packaging is placed on the formed opening of flap exactly, but also will be correctly all edges of two openings be pasted together, the manufacturing that this installation and the way of sealing just make this packing box is difficulty very, but also needs to use Special Equipment.

Secondly and since the material of the material of this packing box opening portion and packing box the same be rigidity or semi-rigid, so its flexibility is relatively poor, in order to obtain having best flowing velocity when product is poured out, so opening is shaped.

The objective of the invention is to avoid fully the shortcoming of above-mentioned packing box, propose a kind of brand new packing box open design, make packing box practical more, it is also convenient more to use, and it is high that service efficiency is wanted.The packing box of this redesign, its inner soft packaging bag was just loaded good the packaged products of wanting and is put it into packing box before putting into external packing box, thereby it does not need special equipment to settle packing inside bag, does not need special equipment to make and form opening on it specially yet.

For this reason, one of purpose of the present invention just provides an inside to be had a soft packaging bag and has a folding packing box that can seal opening once more, this packing box has a rigidity or semi-rigid external packing shell, it has four surfaces, but extend to form two pairs of relative closure flap separately, what also have a tubulose also descends two ends to have the inside soft packaging bag of transverse sealing thereon, it is characterized in that:

-said opening is positioned at angle on one of them of said tubular inner packaging bag, just in the end of its transverse sealing, and additional thereon section made from semi-rigid material, section is positioned on the transverse sealing limit, and its top of said opening flushes with said transverse sealing limit and just diverges to be positioned at and is connected on the sealed at both ends up and down edge line;

But have port on the top closure flap of-said external packing shell, angle corresponding to said section, and a knock-down flap is arranged on the wall of the limit of said packing box, its position flushes with said section, just form an opening when this flap is opened, the opening on the said packing inside bag is just by above-mentioned opening and dug;

The corresponding manner of packing of this packing box has several significant advantages.

Because no longer being made on the said rigidity external packing shell, said opening is made on the said inner soft packaging bag, and owing on soft packaging bag, increased by a semi-rigid section, so the design of external packing shell is just very easy.Design as for inner soft packaging bag is simple too, this be because, in fact said opening on it is independently pasted the part that is sealed by one and is formed, in fact be a common section, only its shape is more special, but make than being easier to, and just can on said inner soft packaging bag, form this opening, and be before packing inside bag seals, just can carry out with common machine (such as price labeling).

In a most preferred embodiment, its shape of said section is a rectangle or foursquare, the pre-otch that has on it in otch, the section forms opening work guiding usefulness for tearing packing inside bag on angle of inner bag, tear inner soft packaging bag along this groove and just form said opening, also have the slit of a periphery to be used for said section is hung over said open channel edge in addition, and the opening on the said packing inside bag is just by opening and dug.

The width of the said section width with the little limit of Package casing wall basically is the same, and fork is positioned on the edge of packing box, determines that by the Xiao Bianbi of said packing box and top at this moment, packing box is folded, and the packed filled with product of interior packing.

According to this most preferred embodiment, the part of the top that is folded to said packing box of said packing inside bag more preferably is clipped in after one of them flap than the long edge break wing and other two adjacency of external packing shell, have a corresponding otch to be used for making the opening on the packing inside bag to dig on the said long edge break wing, its adjacent part comprises two knock-down parts of making by pre-otch on the flap of two adjacency.

Said pre-otch is used for leading to tearing inner soft packaging bag, its shape makes-V-shape, it determines the profile of said opening, it is positioned at the center of said section and last part, and stop along with the edge of opening of peristome similar on the top seal band that is positioned at inner soft packaging bag, form a reference position that is used for tearing at last.

A kind of like this open design has kept the globality of soft packaging bag, in any case particularly consider the mechanical resistance and the tensile force that also can not be reduced or weaken.

In fact the sidewall of said opening is formed by the sidewall at angle on one of them of packing inside bag, in case this angle is torn, the otch of external packing shell is just as a mould, and it provides corresponding space, position and to the resistance of said opening.

The shape of the semi-rigid characteristic of the material of said section and packing inside bag opening makes that with the position that enters the upper shed of external packing shell it is very easy closing said opening again, because only by the opening profile is flattened, said opening just can be closed in using.

Because said opening only is to form by the section that has increased a tag-shaped on the outward flange of inner soft packaging bag, so, this section can just can be finished with a kind of machine (such as price labeling) easily, before packing inside bag forms tubulose as yet, on the one flat plate material, do not form, or formed tubulose and vertically sealed but also do not carry out being shaped before the transverse sealing at packing inside bag.

Its its feature and the advantage of package according to the invention will come into plain view from following explanation about packing box most preferred embodiment of the present invention, below, be described in detail with reference to corresponding accompanying drawing.

In case Figure 13 represents to close after the packing box one-shot usage is finished the method for said opening;

Figure 14 represents another embodiment, its objective is as can be seen by structural change to obtain different openings.

In Fig. 1, shown soft packaging bag comprises a tubular body 1, and it is made by a kind of very thin hot plastic film, it by with the parallel sidewalls of tubular body 1 and seal with the sealing band 2 and 3 of sealing band quadrature on the sidewall.

Sealing band 3 is perpendicular to sealing band 2, also perpendicular to the connection lead 4 of sealing band 3 end points between up and down.

The two ends of the tubular body 1 of Xing Chenging are defined by transverse sealing band 3 thus, and under the three-dimensional state space, two angles 5 on it are similar to taper substantially, and the design according to the present invention of one of them angle forms said opening.

For this reason,, on an angle of tubular body 1, add one, preferably paste a section 6 of (planar view) as shown in Figure 2 according to the present invention.It is made with semi-rigid material (such as plastic film or the moderate plastic wrapping paper of width).

Among the embodiment that here shows, the shape of section 6 is foursquare basically, it has two mutually perpendicular centre fold 7 and 8, just in time be positioned at the groove 9 of a V-shape of the midway location of upper limb 10, V-shaped groove 11 is positioned at the midway location at edge 12, two V-shaped grooves 13 connected to one another are positioned at the midway location of lower edge 14, and a pre-otch 15 of V-arrangement is positioned at the first half 6a of section 6, and said pre-otch 15 stops with the end that is positioned at the V-shaped groove 16 on the upper limb 10.

Groove 11 is connected to groove 9 by broken line 17, is connected to groove 13 by broken line 18, also we can say by broken line 17 and 18 to be connected to groove 13, and broken line 7 and 8 is by broken line 17 and 18 determined little foursquare diagonal lines.

Groove 13 has been determined a summit 19, and its both sides overlap with said broken line 18.

A limit of groove 16 overlaps with a limit of the pre-otch 15 of V-arrangement, thereby has defined a corresponding part 20, and it can separate 6 from cutting into slices and comprise groove 9 and be V-arrangement.

In Fig. 1, two buses 21 of tubular body correspond respectively to corresponding two limits of external packing duricrust 1, as shown in Figure 4, when product being housed and when correspondingly configured in the packing inside bag, it and external packing carton box body big or small basic identical and be all parallelepiped.

Section 6 width equals the distance between above-mentioned two buses 21 of packing inside bag, that is to say that almost equal the width of the little wall of external packing duricrust, at this moment, inner soft packaging bag should be the inside of filling product and being placed on the external packing shell.

Section 6 can be easily with a kind of adhesion agent affix, and it is secured at along said broken line 4 on the outer wall of packing inside bag 1 of sealing, in case all seal all finish after (sealing band 2 and 3), edge 10 just is on the same horizon with transverse sealing band 3.

Broken line 8 is corresponding to line 4, and edge 12 is corresponding to bus 21, and broken line 7 is corresponding to packing inside bag 1 filling product and the later edge that is shaped, and this moment it and external packing shell the corresponding edge wall parallel, size is basically identical (as shown in Figure 4 and Figure 5) also.

Section 6 can be made on packing inside bag 1 with a kind of price labeling easily, can be still before the unshaped at packing inside bag, additional thereon when still being the one flat plate material when it, also can additional again section 6 when packing inside bag 1 has formed tubulose and vertical and horizontal sealing and all finished.

It is dry, granular or pulverous that Fig. 3 represents that inner Soft Roll is equipped with, or the product of liquid, and be configured as a rectangular parallel piped shape and make situation when it can be inserted into the collapsible external packing shell of a parallel tubular shape.

In view of the above, packing inside bag 1 is shaped to feasible two the little limit walls that form, and one of them (representing with label 22) defined by edge 21, and its shaped upper part is a rectangle, sealing band 3 extends along a diad of this rectangle, and limit wall 22 folds into the upper surface of packaging bag.

Be a triangle after angle 5 expansion are straight, this triangle is to form by each angle along broken line 17 folding sections 6.

Groove 9 crosses the tip point 23 of packing inside bag 1.

Launch straight relief angle 5 in this way and be folded to the upper surface of parallel tubular shape packing inside bag 1, at this moment, packing inside bag 1 is inserted into folding external packing shell, and the external packing shell just is closed subsequently.

Fig. 4 has represented a package according to the invention, and it is used for splendid attire soft packaging bag shown in Figure 3.

Comprise two big limit walls 24 and 25, two little limit walls 26 and 27 at the half-blank carboard that has otch and groove shown in Fig. 4, they all have closed flap at each end.

The structure of this packing box is traditional, and has only the closed flap in top and said little limit wall can arrive opening and opening can be launched making in shape.These little limit walls with place the section on the inner soft packaging bag 1 in the same plane.

In view of the above, said little limit wall 26 in its upper end, comprises a knock-down part, and this part makes a leg-of-mutton flap 28, and its tip down.Should be noted that, the pre-aperture lines 29 of the V-arrangement of said flap intersects with the parallelepiped packing inside bag edge 7 cooresponding upper limbs 30 shown in Fig. 3, near the angle of the certain distance of the external packing shell of distance adjacency, the width at flap 28 10 places at the edge is slightly less than the width of limit wall 26.

The top flap 31 that links to each other with wall 26 comprises a knock-down part, and this part is formed by a trapezoidal flap 32, and this trapezoidal flap determines that by pre-cut line 33 line 33 links to each other with line 29, and intersection point is 30 places at the edge, and line 33 ends at crescent otch 34 places.

Top flap 35 that two are adjoined and 36 edge are designed to especially can be suitable with flap 31, and top flap 35 and 36 then is connected respectively on two bigger walls 24 and 25.

Flap 35 comprises the otch 38 of knock-down part 37, one crescent, and they correspond respectively to the unit 32 and 34 on the flap 31, and when packing box was closed, these two parts overlaped, and flap 32 and 37 opposite edges 10 form the symmetric part of flap 28.

Flap 36 comprises a trapezoid-shaped openings 39, and its outline is slightly smaller than the width of flap 36, and its reason is explained below with reference to Fig. 7.

Fig. 5 and Fig. 8 have represented each different phase that packing box is closed after the soft packaging bag 1 after loading has been inserted into external packing shell and said packing box and fixed in space.

Outwards roll at angle 5 after the flattening, and flap 36 at first is closed, with relief angle 5(as shown in Figure 6) be folded to said flap 36.Opening 39 has corresponding size and places corresponding position to make a female role 5 be folded to flap 36, and flap 31 just is folded to corresponding angle 5, in the middle of angle 5 is sandwiched in, and makes packing inside bag 1 and external packing cap closely combine.The advantage of doing like this is that the inside face of flap 36 can be bonding, thereby makes packing inside bag and external packing shell closely be pasted together.

Flap 35 puts in place (as shown in Figure 8) at last, its purpose is that making the outside of packing box under normal circumstances is that a parallelepiped outside face is fairing, there is not projection thickness, crescent 38 appears at the top of packing box separately, make and to open flap 37,32 and 28(as shown in Figure 9), its objective is in order to arrive opening.

When opening flap 32 by crescent moon 34, adjacent flap 28 also is opened under the situation that this opening action continues.

The first half 6a of section is opened on flap 35, and the latter half 6b then is exposed in the V-arrangement opening 29 on the wall 26

Following step (as shown in figure 10) comprises by drawing angle 5 coilings, 7 rotations that it is dug.If the rotational motion around line 7 continues outwards (as shown in figure 10), section 6(is as shown in figure 11) just be forced to bending by opening 29, the width of opening 29 is deliberately done forr a short time than the width of section 6, and purpose is to force to make section to form the shape of represented among Figure 12 and 13 opening.

This rotational motion continues at the level attitude that appears at opening 29 bottoms (groove 13) to groove 11 and 13 always, groove 11 and upper level edge 10 flush, the action effect that one elastic recoil is arranged when so just making the angle 5 of packing inside bag 1 be released, section 6 are tilted on the carboard of pack case outward.

The opening of Xing Chenging just has fixing position therefrom.

In case opening is unfolded, the summit at angle 5 (as shown in figure 11) just can be torn, although this operate in opening and be unfolded fully before easier being done, in other words, before the lower part 6b of section was inserted in the groove 29, groove 29 was positioned on the wall 26.The initial point of tearing angle 5 comprises a recess 40, and it is positioned on the free edge of sealing band 3, recess towards with otch on groove 16 towards consistent.

(as shown in figure 11) manually torn at angle 5.Tear line arrives notching edge then by groove 40,16, and the edge of opening is defined up to broken line 8 by pre-aperture lines 15.

In case the summit of said soft packaging bag 1 is torn, just determine an opening by the line 15 of section 6a as shown in figure 12, the groove 9 that is made on otch 20 parts is designed to be positioned on the free end points at angle 5, and it is very convenient when being placed into the external packing duricrust to make that the triangle of the first half 6a of section is folded in the inside flexible packaging of having loaded product, and groove 9 is just torn when using opening for the first time.

The best part of opening (as shown in figure 12) is to obtain by the sealing band 3 that tears section 6a part, and the section 6a partly be fixed remain the projection, and remain on its corresponding position, because it is locked by the sweep of groove 11,13 and said otch.

It should be noted, flow out the product mouth of opening, except said opening inwall to the material of the soft packaging bag 1 at edge 15, will not contact with other material.

When the end of sealing band 3 only is brought to section 6a(as shown in figure 13) near when closing otch, the opening after using is closed once more even is more prone to.The elasticity of crooked section 6a is tending towards stressing on the limit wall part, and they form a suitable application force of closing opening towards packing inside bag 1 also toward each other therefrom.

Therefore package according to the invention can store (as shown in figure 13) and can use at any time again.Draw back sealing band 3 and just can reopen opening, as shown in Figure 12.

Broken line 7 and 8 is designed to be arranged in the tram (when soft packaging bag 1 is inserted into external packing box) of opening, just forms said opening when it is unfolded or locks onto its corresponding position.

The design of said opening outline, what that is to say pre-opening 15 positions and shape determines that the characteristic of corresponding product in the soft packaging bag 1 and viscosity selects according to being contained in, said otch 15 has crooked part or makes meniscate such as doing forming V-shape.As label among Fig. 2 15 ' represented, the pre-opening of V-arrangement can extend in the first half of whole section 6, and on the point of crossing of V-arrangement summit corresponding to broken line 7 and 8, the angle at V-arrangement angle is variable.It is 90 ° that this embodiment allows angle folding, and this angle flushes along broken line 7 and with the flap 35,36 of packing box, section 6 each several part be positioned at the pre-opening 15 of V-arrangement ' both sides on.

The identification of position of section 6 on packing inside bag is such, and when making the packaging bag of a string known way when forming a transverse sealing from a hot plastic film material, said packaging bag is just loaded simultaneously, and corresponding slice position just is formed.Therefore section 6 is placed in corresponding position on the tubulose packing inside bag outside face, and this is by realizing by the price labeling of a standard at the filling station.

Should be noted that in the packaging process of complexity, according to the present invention, packing inside bag 1 is easy to separate from the external packing shell, therefore, can recycle the material of making the external packing shell again, also is the same to the material of making packing inside bag.

Packing inside bag 1 also can be used as vacuum vessel, also can inflated with nitrogen or other neutral gas.

At last, the present invention is not limited to the above embodiments, on the contrary, it has comprised all various variations, particularly for the shape of additional section 6, size and characteristic, and be fixed to method on the opening (29), and for the variation of the method that forms said opening on the wall of pack case outside and the closed flap etc. all unqualified.

The present invention can be used for cubical packing box, perhaps is called the equal packing box of width of wall 24 and 27.

The opening of packing box also may be on its less wall, but on its bigger wall 24,25, therefore, can have bigger A/F this moment.Therefore packing inside bag 1 also can be placed in the external packing shell, but this moment its top seal band then be positioned at equally with the big wall of packing inside bag equidirectional on.The angle that forms opening and otch is corresponding to the section 6 of the embodiment shown in here, it then extends on the whole width on said big limit 24,25, be on the angle of upper limb of said big wall, be slightly less than the width of big wall corresponding to the width of the flap of flap 28, because it is also corresponding to said flap 28 aforesaid situations.

The formation of other top flap is such, and promptly under the situation identical with previous embodiment, easily near opening, little flap is folding in advance before big flap is folding.

In the embodiment shown in fig. 5, soft packaging bag 1 comprises two relative angles, and they are inwardly folding.Consider different method for folding, the last angle 5 that also might need not fold soft packaging bag forms opening, and at this moment, soft packaging bag is not exclusively filled.Said angle 5 is advanced in the soft packaging bag 1 a little, presses to the top of little wall 26 simultaneously.

Further, the sealing lip of soft packaging bag 1 no longer is two parallel sealing lips, but a shared sealing lip, this shape makes opening be positioned on the bigger wall 24,25, locatees to be more prone to when packing inside bag 1 is put into the external packing shell.

At last, according to another embodiment shown in Figure 14, be positioned at knock-down flap 32 on the top flap 31 ' protrude at less limit wall 26, the pre-aperture lines 33 of flap 32 ' and the separable flap 28 of wall 26 ' separately ' and 29 ', intersect at online 30 places, line 30 ' be parallel to edge 30 but it is positioned on the wall 26.According to this embodiment, section 6 is positioned on the soft packaging bag 1, its purpose be to make broken line 7 similar with said line 30 ' be in sustained height.This handling allows under the less situation of the width of limit wall 26, and opening has a tangible outline, so just can more said opening lockout (be seen the zone 41 of beating hatching among Figure 14) on Qi Bianbi.
