Description

Container

Technical field

The utility model relates to a kind of tight container that can repeat to cover, and particularly relates to a kind of paper-plastic multi-layer composite packaging container that is used for receiving fluids or pasty product, and it has an oblong bottom; Four orthogonal substantially side surfaces in position (body surfaces); A head zone, this head zone after described packing is filled with a banded joint seal; A closure elements, this closure elements are positioned on the inclined surface of described head zone.

Background technology

At the disposable beverage packaging field, now prevailing is known just parallel tetrahedral card board package.This packing exerts an influence to productive costs, that is, if necessary, sterile filling, dispensing is the factor that will calculate when wholesale and retail, has tangible advantage in the shop and in the storage without a doubt of customer there.Except these positive factors, the variety that product is used also is worth emphasizing.Therefore, for example, the characteristic of various products obtains by using graphical element, and the variable performance of described graphical element is allowed the multiple different outward appearance of acquisition when considering structure.The container of this carboard type and other disposable beverage for example pack barrel-type bag packing, light metal jar or glass and plastic bottle etc. mutually specific energy many advantages are provided.

Yet, to compare with the container of bottle type, it is can the aspect relatively poor that the repeating of this packing covered sigma compactness.Development in recent years shows, failure-free repeat to cover sigma compactness can importance can not ignore, because packing measurement (home-use packing) has increased on market widely, so because the performance that re-covers tightly of this high this packing of filling capacity just seems very necessary.Usually, can repeat to cover tight carboard composite material vessel and have suitable and known closure elements really, yet the degree that the customer accepts them is slow.This may mainly be because the known closure elements that this class is used for carboard disposable beverage packing in a way impracticable of operation be unfamiliar with, particularly it can not the evacuation beverage or can not reach the closure requirement of expection.(when being subjected to rocking, still can keep sealing).

Many known packings provide good operating characteristic really and can repeat to cover the sigma compactness energy, still, have paid very important factor beastly (as the piling performance) in order to reach this benefit.The disadvantage of coming up that can say mainly contains, and the closure elements that protrudes from the packing of positive parallelepiped shape must have certain height, makes that they are easy to use when opening and tightening again.Yet this whole height causes having problems when piling, even after the transportation of reality, the operation owing to carelessness in the shop might be torn off other closure elements by chance from packing.

In order to address this problem, German patent specification 4015119C2 discloses in the head zone of packing a bevelled surface has been set, on described inclined surface fixedly closure elements so that avoid described closure elements from positive parallelepiped upper process.Yet this known packing also has disadvantage, thinks that it needs bigger head space.

Summary of the invention

Therefore, the purpose of this utility model is exactly to implement and known repetition of improving above-detailed covered tight container, makes the advantage of the best and don't loss known containers of the volume of described container at production, filling and seal aspect.With the exception of this, this unrolling of container part and can protect the influence and the destruction of the power that the closure elements that adopted do not applied by the shape of launching the packing that part obtains.In addition, the formation of expansion part has been considered the fundamental principle in the current manufacturing technology at least.

This purpose reaches by following manner, promptly, when packing is folded to form, the inclined surface that carries described closure elements is outstanding from the oblong profile of being determined by container base at least partly, thereby the body surfaces that is positioned at below the closure elements has a projection, and the body surfaces relative with described raised bodies surface has a corresponding recess at least in head zone.According to the utility model,, can guarantee the ratio of the best of filling volume and vessel volume owing to the effect of described projection.According to embodiment of the present utility model, the front of described packing has a projection, this projection continuous, save the piling aspect of performance space, stable and can produce passive influence.In order to eliminate the influence of described passiveness, be provided with a recess in the back of described packing head zone, this recess is described projecting mating thing, this is to realize by the arrangement according to fold line of the present utility model.By corresponding recess in the relative zone of described packing, just can satisfy the needs of good piling performance.About this point, can imagine that the inclined surface of described closure elements and installation closure elements is all considered their sizes each other by cutting, make to obtain corresponding protection effect and optimum piling performance in this way.Opposite through the head that changes with described packing, the structure of bottom keeps the situation of prior art.

According to the embodiment that selects of the present utility model, the banded seam that is arranged in the head zone can be towards described inclined surface bending or towards the direction bending away from it.Yet, in any situation, all with different according to disclosed container among the Germany Patent document 4015119C2, employing is that it always extends perpendicular to the direction of described inclined surface according to the advantage of banded seam of the present utility model, makes " ear of packing " be pressed against on the body surfaces adjacent with the body surfaces with described inclined surface.

According to another one embodiment of the present utility model, the tapering of described projection and/or recess zone from the head is uniform towards bottom section.Simultaneously, the fold line that forms described projection and/or recess can extend to the inferior horn of packing, perhaps in the positive lower edge of the folding corner region end of packing in the body surfaces that has described inclined surface.

Yet if described projection and/or recess extend downwardly into the container height position of half substantially in the zone from the head, the utility model also can be implemented.And verified be enough to reach according to closure elements of the present utility model can repeat to cover tight and make things convenient for the advantage of piling in dispensing, in selling.

In Fig. 1 and 2, first embodiment according to container of the present utility model is shown in the mode of block diagram.In this case, described container has rectangular base portion, does not illustrate in further detail in the drawings; Also have four orthogonal substantially each other side surfaces, that is, and

body surfaces

1,2,3,4.In head zone, described container is by banded seam 5 sealings, and leg-of-mutton " ear " 6 is bent downwardly and is attached on body surfaces 3 and 4.In the head zone of body surfaces 1, can see a bevelled surface 7, this surface highlights from the container rectangle profile that is pre-determined out by described base portion, is fixing 8 one screw cap of a closure elements as this closure elements on described inclined surface 7.Therefore, the body surfaces 1 that is positioned under the described closure elements 8 has a projection, make this surface on the main body of positive parallelepiped shape to outer lug.Body surfaces 2 on the other side (back body surfaces) is provided with a recess correspondingly, does not illustrate in further detail here, can illustrate in further detail hereinafter.

In Fig. 3 to 5, according to container of the present utility model shown in three different side diagrammatic sketch.For simpler, explain in further detail with reference to the description that it launches part according to container of the present utility model.Figure 6 illustrates according to unrolling of container part of the present utility model, it can be made by any favourable material, and preferable material is for typically being used for the composite material of disposable beverage packing.In the diagram as can be seen, described expansion part comprises a square sheet material of suitable material.

Vertical bight line

9,10,11,12 and edge line that this square sheet material is unfolded part are divided into five main areas, just 1,2,3,4 and longitudinal seam bars 13 of side surface afterwards.In this case, by the

vertical bight line

9,10 that launches part and/or 11,12 and the main areas 3 and 4 of edge limited formation up and down be identical.

Yet main areas 1 is being different with 2 aspect several key characters.By the vertical bight line 10 of described expansion part and 11 and up and down edge line limit the main areas 1 that forms and have a rectangular region 7 (inclined surface afterwards) in the middle of being positioned at an upper portion thereof in the zone, this rectangular region is used for installing described closure elements 8.For this reason, in zone 7, a strength reduction zone is set on described composite material, for example a hole 14.Some fold lines extend to the angle point of

triangle

15 and 16 from zone 7 angle point, and described

triangle

15 and 16 has formed the ear 6 of packing afterwards.Two following angle points in zone 7 all are connected to zone 1 by

fold line

17 and 18 and stop with the point of crossing place of sheet material edge fold lines 19 formation and in the bight.The position in zone 7 is that can change and relevant with the height of needed space and/or closure elements 8 with its size.In order to obtain best piling, the size of respective surfaces 20 and position are determined so to be that they are in the vertex of closure elements 8 is in the identical horizontal surface on the surface in the zone 7 that the suggestion preamble is described and the rear wall 2.

Fold line

21 and 22 also has in the main areas 2 of back, so that make that recessed rear surface is stable and provide a supporting role.Described fold line extends to the point of crossing in the zone 2 that forms with sheet material edge fold lines 19 from surface 20 bottom angle point, and extends to the bight from the bottom angle point on surface 20.

Main areas 3 and 4, and the whole lower area (being positioned at the bottom of launching part edge fold lines 19) that launches part will not do explanation is corresponding because typical cases of these zones and known positive parallelepiped-shaped composite packaging launch part.

In Fig. 7 to 12, described another one embodiment, and some reference numbers correspondingly have been set.This embodiment according to container of the present utility model illustrates a body surfaces 1 ', and this body surfaces enters into a trapezoidal inclined surface 7 ' in the head zone of container, and described trapezoidal inclined surface is used for installing closure elements 8.Can see in the expansion part of this embodiment of the utility model container shown in Figure 12 that the respective surfaces 20 ' of back body surfaces 2 ' also is arranged to trapezoidal.

In this kind situation, the fold line 17 ', 18 ' and/or 21 ', 22 ' that extends below inclined surface 7 ' and/or surface 20 does not extend to the bight of container, but in the outside in container bight, the inside and the sheet material edge fold lines 19 on surface 2 ' are met.Such measure has following advantage, that is, fold line 21 ', 22 ' may be directed to outside two material guide member (longitudinal seam 13) zones.Certainly, such design also can be implemented in first embodiment shown in Fig. 1 to 3.

At last, in Figure 13 to 18, the another one embodiment according to container of the present utility model has been described.In this case, the head zone of container is substantially corresponding to the head zone among first embodiment (Fig. 1 to 6).Yet in this case, banded seam 5 is bent to an other side so that inclined surface 7 " bigger than among first embodiment.This point can be more clearly visible from Figure 18.In the expansion part that illustrates in this embodiment, can see that banded seam 13 ' is not formed in the back side of container, and be formed in the front of container, be formed on body surfaces 1 specifically " on.For this reason, banded seam 5 is bent and makes its point to away from body surfaces 1 " and/or inclined surface 7 " direction, thereby avoided longitudinal seam to bear very strong material bending.

With the exception of this, in Figure 13 to 18, can find out fast to be positioned at surface 7 " and/or 20 " below fold line 17 ", 18 " and/or 21 ", 22 " do not extend to sheet material edge line 19, but approximately arrive the middle part of container.Such an embodiment more economically, however, still can realize advantage of the present utility model for launching part folding.
