Description


  Conical packaging with improved tear opening

  
description

  
The present invention relates to conical packaging, in particular tapered packaging, preferably for foodstuffs such as ice cream in waffles and the like, having a packaging wall tapering from an axial discharge end along a packaging axis, the packaging wall providing a tear-open aid with a first material weakening of the packaging wall material and having a second material weakening extending away from the first weakening of the material such that the first and second weakenings of material define a tear strip therebetween.

  
A generic packaging is known from EP 0 226 958 A. In the known bag-shaped pointed conical packaging, a perforation defined by two essentially parallel perforations circumferentially about the packaging axis is formed as a tear strip defined as the material weakenings which can be completely torn away from the conically tapered packaging wall in an axial middle region of the packaging, so that after complete tearing off of the package Tear strip a frusto-conical upper packaging part and a by the width of the tear strip of this spaced-apart conical lower packaging part remains.

  
A disadvantage of the known packaging is that the upper packaging part, which usually has to be removed in such packaging in order to reach the packaged product, remains even after the tearing-off of the packaged contents. Since this upper Verpackungsteii itself is frusto-conical and tapers from the largest packaging cross-section along the packaging axis, this is not readily strip along the packaging axis of the packaged, usually also conical Good and must be in turn costly removed by further opening actions ,

  
From EP 1 484 251 A, a pointed conical packaging is known in which a circumferential line around the packaging axis is provided along which an upper, ie the region of larger packaging cross-sections comprehensive packaging part unwound in the circumferential direction and thereby demolished by a lower conical packaging part can.

  
A similar tapered packaging is known from DE 100 56 811 A. In this a tear line is introduced by laser processing in the circumferential direction around the packaging axis in the packaging, so again with the aid of a tear tab on the peripheral edge of the conical packaging formed by winding an upper, so larger packaging sections associated portion of the packaging by unwinding around the packaging axis of a lower Packaging part can be separated.

  
Reference is further made to US Pat. No. 4,657,142 A, which shows a conical packaging in which, similar to the afore-mentioned generic EP 0 226 958 A, a tear strip defined by two essentially parallel weakenings of material is provided circumferentially around the packaging axis, wherein after removal of which two spaced Teilverpackungswandungen remain on the packaged Good.

  
Starting from the above-described prior art, it is an object of the present invention to provide a conical packaging of the type mentioned, which can be opened more easily than the packaging of the prior art. This object is achieved according to the invention in that, in the case of packaging of the type initially mentioned, the tear strip runs starting from the removal end of the packaging with a tear component in the direction of the packaging axis and ends in an axial middle region of the packaging.

  
With the inventive conical packaging, it is possible, starting from the axial removal end by removing the tear strip along the two material weakening defining it to create an outgoing from the Axialmittelbereichs removal end, ie the end of the largest packaging cross section of the conical packaging, outgoing gap, which is also in the direction the packaging axis extends into the Axialmittelbereich inside.

  
Characterized in that the tear strip approximately in the Axialmittelbereich the package, ie in a axial packaging ends including the withdrawal excludes symmetrically about the axial center of the package extending range of about 15-85% of the packaging height, preferably 30-70% of the packaging height particularly preferred 40-60% of the packaging height ends, a material context of the conical packaging may initially remain when opening, ie the tear strip is activated without the packaging breaking up into several pieces.

  
Then, starting from the gap formed by the tear strip, the axial opening region of the package, ie the axial region along which the tear strip has extended, extends along an imaginary peripheral groove connecting the removal ends of the tear strip and the nip produced by the tear strip, respectively be folded so that the hand of a person who holds the conical packaging at its gap-free axial portion, the still intact gap-free axial region of the conical packaging can grip while the hand is radially outwardly surrounded by the folded packaging material sleeve-like, so that the hand , as in the case of packaged wafers, is protected by the folded packaging part from contamination by melting ice cream.

  
The term "Ent [pi] ahmeende" in the present application, the longitudinal end of the conical packaging is designated with the larger packaging cross-section. In principle, it is conceivable that the packaged product can be removed from this end through an opening in the conical packaging, even though the rule described above is that the material context of the packaging is at least partially destroyed and the package contents are exposed by forming or even partially removing the packaging wall becomes.

  
If it is desired to completely remove the tear strip from the packaging according to the invention, it may be provided to facilitate removal that the package has a third material weakening in the axial center area which extends substantially circumferentially or at least with a circumferentially extending component about the wrapping axis. The third material weakening may preferably define a longitudinal end of the tear strip remote from the removal end of the packaging.

  
In order to facilitate the folding over of the opening region of the package which is changed by tearing open of the tearing strip and gap formation, it can be provided that the dimension of the third material weakening in the circumferential direction is greater than the width of the tear-open strip in the circumferential direction.

  
In order to further facilitate the folding over of the package opening region which has been changed by the formation of a gap by means of the tear strip, provision can be made for the third material weakening to run around the packaging, preferably to circulate closed. In this case, the third weakening of the material, as known from EP 1 484 251 A, can also help the consumer to fold the gap-prone opening region of the packaging not only around the third weakening of the material to form a sleeve but to tear it off the axially adjacent intact gap-free packaging section.

  
The complete tear-off of the tear strip from the packaging can in other words also be ensured by the tear-off strip located at least in sections, preferably with its longitudinal end region remote from the removal end, particularly preferably completely in the circumferential extension region of the third material weakening. Then, the third weakening of the material can form a tear-open point of the tear-off strip extending in the width direction of the tear-off strip.

  
While in the prior art known tear strips usually from peripheral edge to peripheral edge of the package forming piece of material, the tear strip of the package of the present invention begins at the axial withdrawal end, so an axial edge of the package, and preferably does not terminate at a peripheral edge or a other axial edge of the package, but rather ends preferably "in the material". Again, the complete removal of the tear strip can be ensured by the fact that it ends with its remote from the removal end longitudinal end of the third material weakening. As a result, the tear strip can first be torn open along the first and the second material weakening and then torn off along the third weakened material.

  
A particularly advantageous opening behavior of the packaging according to the invention can be achieved in that the first and the second material weakening have different lengths. Thus, the prerequisite is created that the tear strip is first torn open along its extension direction and thus at the axial portion with larger packaging cross sections a gap extending in the axial direction is generated, the tear strip due to the shorter [pi] training one of the two material weakenings with the gap-containing opening area of the packaging remains in the context of material.

  
Then, when a material weakening of first and second material weakening reaches and preferably ends up to the third weakening, and if the other weakening is shorter than one weakening and ends away from the third weakening, the tear-open tab may be initially along its direction of extension was separated from the rest of the packaging, continue to be used to initiate a crack in the package along the third material weakening in the material connection with the then gap-prone opening portion of the package and thus to separate the gap-prone opening portion of the package from the axially adjacent intact gap-free packaging portion, so that the packaging is essentially a single continuous movement,

   preferably with initially predominantly axial component of movement and then with predominantly circumferentially extending component of motion, can be conveniently opened and an intact packaging section remains in the consumer's hand, while a continuous piece of packaging waste is obtained, which can be easily disposed of.

  
It can further be considered that the tear strip extends not only in the axial direction along the packaging axis, but that adjoins a further tear strip section running substantially in the circumferential direction at at least one tear strip section running at least in the axial direction, preferably in one piece.

  
For this purpose, it may be provided that the conical packaging of the present invention comprises a fourth material weakening, which, starting from the longitudinal end of the respective other shorter Materiaischwächung from the first and the second material weakening, preferably parallel to the third material weakening, extends substantially in the circumferential direction, preferably rotates.

  
To facilitate gripping the tear strip, the conical

  
Be further developed packaging such that at the closer end of the tearing strip a gripping tab is provided which protrudes over an edge of the package, preferably the axial edge of the package at the removal end.

  
A tearing open with a tearing force that is as constant as possible can advantageously be generated by the first and the second material weakening being parallel, at least in sections, preferably completely.

  
Basically, it is an object of the present invention to provide the tear strip an opening region of the package in the region of larger packaging cross sections, wherein the packaging wall has a gap extending at least in the axial direction and an axially intact, in the direction of the packaging axis, adjacent intact packaging section in the area smaller packaging cross-sections to preserve, in which the gap formed by the tear strip does not extend into it.

  
For this purpose, it may be provided that the first and the second material weakening run in a direction of weakening, which has a component in the direction of the packaging axis. In the simplest case, both the first and the second material weakening lie in a common plane with the packaging axis. The result of this is a substantially straighter and therefore as short as possible along the packaging axis from the removal end away tapering tear strip, which has no other course component on the conical packaging wall as an axial component. However, it can also be thought to extend the tear strip approximately helical to increase the gap formed by the tear strip.

   For this purpose, or else for other courses of the tear strip, it can be provided that the first and the second material weakening run in a direction which has both a component in the direction of the packaging axis and a component in the circumferential direction.

  
Furthermore, it can be thought that the tear strip runs at least in sections, preferably over its entire length, meandering.

  
In principle, it can be thought that the packaging wall material in the region of the discharge end of the package has such a large packaging surplus that thus the opening cross-section of the conical packaging can be closed like a lid.

  
For the filling and opening of the packaging, however, it has proved to be more advantageous if the conical packaging comprises a lid which is formed separately from the conical packaging wall and which is held on the packaging wall. Preferably, the lid is positively held on the packaging wall, such as by crimping the packaging at the discharge end of the package radially inward, ie on the packaging axis, whereby the fold formed on the lid comes to rest and thus prevents lifting of the lid.

  
In order to produce a cost-effective packaging, the packaging wall material may comprise a paper layer. Paper layers have the advantage of low restoring forces after their forming.

  
This paper layer may have the above-mentioned material weakenings. For better protection of the contents of the package from external influences it can be provided that the packaging wall material comprises a laminate of at least two layers. It can be thought that only a part of the layers of the laminate having the above-mentioned material weakenings, so that at least one laminate layer is substantially intact and undimmed.

  
For example, for better shelf-life of foods, which are preferably packaged in the conical packages described herein, the laminate may comprise a barrier layer. Suitable barrier layers include metal layers, in particular metallized layers, such as an aluminum layer, metal oxide layers, such as an aluminum oxide layer or a silicon oxide layer, or also an ethylvinyl alcohol layer. Preferably, the barrier layer is free of material weakening, so as not to impair its barrier function. Preferably, the barrier layer is vapor-deposited on a carrier layer.

  
In order to impart stability to the conical packaging and / or to improve its hygienic properties, the laminate may comprise a plastic layer, wherein preferably at least one plastic layer of the laminate has material weakenings. Plastic layers are particularly easy to provide with material weakenings, such as laser processing. As material for the at least one plastic layer is polypropylene or / and polyethylene and / or PLA (polylactic acid) or / and polyethylene terephthalate (PET) in question.

  
If the laminate, as in a preferred embodiment, has a paper layer, a plastic layer and a metallization layer applied to the plastic layer, then it is sufficient for correct rupture of the spreading strip and optionally for initiating further desired cracks, if only the plastic layer has weakened materials. In addition, the paper layer may also exhibit weakening of the material.

  
As material weakening, for example, a material thin point is considered, as it can be produced by embossing.

  
In particular, but not only when the packaging wall material is a laminate, the weakening of the material may also be a discontinuity of material, such as a perforation. It is usually sufficient if one of several layers is perforated, or it is advantageous if at least one layer, particularly preferably the above-mentioned barrier layer, is free of material weakenings.

  
Also, it may be thought to use for cracking plastic layers with stretched in one direction plastic.

  
Preferably, the package comprises tearing open at the removal end, for instance in the form of notches, which is provided on the removal end side [pi] longitudinal ends of the first and the second material weakening in order to facilitate the initiation of crack initiation.

  
The present invention will be explained below with reference to embodiments in the accompanying drawings. It shows:

Figure 7 A cross-sectional view of a laminate from which the packaging walls of Figures 1 to 6 may be formed.

  
Sn FIG. 1 is a packaging wall of a tapered package according to the invention, generally designated 10. The pointed conical packaging wall 10 extends along a packaging axis V and tapers from its removal end 10a with a large packaging cross-section, which is axial relative to the packaging axis V, to a tip 10b at the longitudinal end of the packaging wall 10 which is axially opposite the removal end 10a.

  
The packaging formed from the packaging wall 10, which can be formed by crimping the axial edge 10c, after a previously not shown in FIG. 1 removal opening 12 a lid not shown in Figure 1 was inserted (see also Fig. 3), extends along the packaging axis V. over the height h. Symmetrically around the axial center of the package 10 at h / 2 extends an axial center area A1 which occupies about 70% of the total height h in the example shown in Figure 1.

  
Starting from the removal end 10a of the packaging wall 10 or the packing formed therefrom, located outside the axial center region A, a tear strip 14 runs on the conical packaging wall 10 exclusively in the axial direction into the axial center region A of the packaging and ends there. The tear strip 14 is bounded in the circumferential direction U about the packaging axis V on one side by a first material weakening 16 and on the other side by a second material weakening 18.

  
In the example shown in FIG. 1, the first and the second material weakenings 16 and 18 run essentially parallel to one another, so that the tear strip 14 has essentially the same width over its longitudinal extension. However, this does not have to be the case.

  
For easier gripping of the tear strip 14, a gripping tab 20, which extends axially beyond the removal end 10a of the packaging wall 10, is preferably formed at its longitudinal end closer to the removal end 10a.

  
At its opposite, so far from the removal end 10a of the Verpackungswandung 10 longitudinal length [pi] de the tear strip 14 can easily end in the material, d. H. it ends where the material weakenings 16 and 18 delimiting it in the circumferential direction U end.

  
In order to allow a complete tearing off of the tear strip 14 from the remaining packaging wall 10, a third material weakening 22 running in the circumferential direction U may be provided, at which the tear strip 14 preferably ends. This means that the first and the second material weakening 16 and 18 extend in the shown embodiment to the third material weakening 22. The third material weakening 22 advantageously extends at least across the width of the tear strip 14, so that its tearing off along the third weakening of the material 22 can be ensured.

  
The axial extent of the tear strip 14 defines on the packaging wall 10 and thus on the packaging formed therefrom itself an opening portion 24 which extends in the axial direction, starting from the removal end 10 a to the axial longitudinal end of the tear strip 14.

  
In the axial direction, a tear strip-free and thus gap-free packaging section 26 adjoins this opening region 24, which remains essentially intact when the packaging is opened.

  
After the tearing strip 14 has been torn off, the packaging wall material of the opening region 24 can be folded around the third material weakening 22, which is advantageously closed circumferentially, according to the arrows M, so that the hand of a consumer can grip the intact packaging section 26 and is covered radially outside of the sleeve-like folded opening portion 24 of the package.

  
Thus, the consumer's hand may be advantageously protected against dripping or dejecting molten ice cream, which is preferably packaged in the tapered packages discussed herein.

  
Figure 2 shows the Verpackungswandung 10 in the settlement as a so-called flat blank.

  
Evident is formed on a peripheral edge 28 folding tab 30, with which the other, opposite peripheral edge 32 is brought to form a so-called "Lap-Seal" compound in overlap and then permanently connected to the folding tab 28.

  
The lap-seal connection can be seen in FIG. 1 in the interior of the packaging wall 10 immediately to the right of the packaging axis V.

  
The first to third material weakenings 16, 18 and 22 are preferably formed by perforation, as will be explained below in connection with FIG. 7.

  
FIG. 3 shows a second embodiment of a conical packaging according to the invention.

  
FIG. 3, in which identical and functionally identical components and component sections are provided with the same reference numerals as in FIGS. 1 and 2 but increased by the number 100, will only be described insofar as they differ from the first embodiment of FIGS. 1 and 2 different. Otherwise, to explain the figure 3 expressly made to the explanations of Figures 1 and 2.

  
On the right-hand side of FIG. 3, a complete embodiment of a packaging 132 according to the invention with a folded-in rebate radially inward can be seen at the removal end 110a of the packaging wall 110. The folded seam edge advantageously overlaps a cover 134, which covers the removal opening 112 of the package 132 or the packaging wall 110. As a result, the lid 134 is held on the packaging wall 110 in a form-fitting manner.

  
This type of attachment of a lid can be realized on all embodiments shown in the present application.

  
Furthermore, the third material weakening 122 may have a stepped shape in the region of the circumferential extent of the tear strip 114, so that the tear strip 114 has a greater axial length in the same position of the remaining third material weakening 122 as in the first embodiment. As a result, the opening region 124 of the packaging 132 is enlarged in the axial direction to the detriment of the tear strip-free and gap-free packaging section 126.

  
Moreover, the second material weakening 118 in the axial direction outgoing from the entrapment end 110a of the package may be made shorter than the first material weakening 116 so that it terminates at an axial distance a before the third material weakening 122.

  
As a result, an opening in the opening area 124 of the package 132 can be created by tearing open the tear strip 114, as in the first embodiment of FIG. 1, but the tear strip 114 then remains in material connection with the remaining packaging wall material of the opening area 124, so that after consumption Packing 132 fewer items to dispose of.

  
Furthermore, in an advantageous development of the present invention, parallel to the third material weakening 122, a fourth material weakening 136 may be provided, which preferably extends in the circumferential direction starting from the longitudinal end of the second material weakening 118 remote from the removal end 110a of the packaging 132 and which starts from the first material weakening 116 extends approximately in the same axial position also in the circumferential direction, but without passing through the tear strip 114. So the tear-open

  
20 strips 114 have a starting from the removal end 110a mainly in the axial direction extending axial portion 114a and in the region of its remote from the removal end 110a longitudinal end of the axial portion adjacent peripheral portion 114b, which extends predominantly in the circumferential direction.

  
25

  
Advantageously, as in the embodiment of FIG. 1, the third and the fourth material weakening 122 or 136 at least run from the first material weakening to the second weakening of the material around the packaging axis. The third material weakening 122 preferably runs closed around the packaging axis.

  
FIG. 4 shows a modification of the planar raw material, which leads to the second embodiment of FIG. As shown in FIG. 4, the fourth material weakening 136 may also be omitted. In addition, the third material weakening 122 may extend only over part of the circumference of the packaging wall 110.

  
5

  
It should be added that also the third material weakening 22 of the first embodiment can extend only over part of the circumference of the packaging wall 10.

  
lo FIGS. 5 and 6 show a third and a fourth embodiment of a packaging wall of a packaging according to the invention.

  
Identical or functionally identical components as in the first embodiment i5 of Figure 1 are provided in the third and fourth embodiment of Figure 5 and 6, respectively, with the same reference numerals, but increased by the number 200 or 300th

  
The third and the fourth embodiment of FIGS. 5 and 6 are explained in the following only to the extent that they differ from the embodiment of FIG. 1, to the description of which reference is otherwise expressly made.

  
The packaging wall 210 of Figure 5 substantially corresponds to the embodiment of Figure 1, except that the tear strip 214 and associated therewith the first and second weakenings 216 and 218, respectively, may meander along the packaging axis V. As a result, the gap area in the opening area 224 of the packaging formed from the packaging wall 210 can be increased compared with the first embodiment of FIG. 1.

  
According to the fourth embodiment of the packaging wall 310 in FIG. 6, the tear strip 314 can run helically from the removal end 310a of the packaging or the packaging wall 310 to the completely and closed circumferential third material weakening 322.

  
The third material weakening 222 of the third embodiment shown in FIG. 5 also runs completely and closed around the packaging axis V.

  
Furthermore, it can be thought to combine the embodiments of Figures 5 and 6 such that a tear strip, for example meandering along a helix line from the removal end of the package or the packaging wall in the axial center region of the package follows.

  
FIG. 7 shows by way of example a laminate with which the packaging walls of the embodiments of FIGS. 1 to 6 can be formed. This laminate 40 comprises, for example, a paper layer 42, on whose one side an aluminum layer 44 can be laminated as a barrier layer. This aluminum barrier layer 44 keeps gases such as oxygen and water vapor away from the interior of the conical packaging, so that foods located inside the conical packaging are longer lasting, as would be the case without a barrier layer.

  
On the side facing away from the paper layer 42 side of the aluminum layer 44, a film of polyethylene terephthalate (PET) 46 may be laminated.

  
In the PET layer 46, a perforation 48 is preferably introduced by means of laser processing, which forms, for example, the first Materiaischwächung 16.

  
It is advantageous that the Materiaischwächung 16 is provided in the laminate 40 only in the plastic layer, more precisely PET layer 46, while above all the barrier layer 44 is intact and thus can fulfill their barrier function. Additionally or alternatively, the paper layer 42 may be provided with a material weakening.

  
However, especially in the case of the combination of paper, aluminum and PET shown in FIG. 7, it is sufficient, due to the stability of PET, to provide only the PET layer 46 with perforations 48. The so introduced perforations 48 act on the entire laminate rißführend so that a suitably introduced into the laminate 40 crack along the material weakenings 16, 18 and 22 is guided and propagates accordingly upon application of force.
