Description

The present invention relates to a tear-open package such as, but not limited to, taper cones used to package ice cream in conical wafers.

Such a tear-open package comprises a packaging material sheet blank having a fibrous layer and at least one further material layer, wherein in the closed state of the tear-open packaging, a closure section of the packaging material sheet blank is adhesively bonded to an unconnected from the closure section connecting portion of the tear-open packaging with the interposition of an adhesive.

The tear-open package is adapted to be opened by destroying the adhesive connection of the closure portion and the connection portion along a predetermined tear-open direction.

A Aufreißverpackung in the form of a conical tip bag for packaging ice cream is for example from the DE 10 2009 024 194 A1 known. This known tear-open packaging has weakening of the material in order to guide cracks in the packaging material sheet blank with a desired course when the tear-open packaging is torn open. The from the DE 10 2009 024 194 A1 known conical tip bag has a course of material weakening, which initially predominantly extends axially from the cone tip remote edge of the conical tip bag and then extends predominantly in the circumferential direction, so along the material weakening separated from the cone tip part of the tear-open and separated the packaged ice cream waffle accessible can be made.

A particular obstacle to opening the tear-open package is the adhesive bonding of the closure portion of the packaging material sheet blank to the connecting portion of the remaining tear-open package. There is packaging material in overlap, so before with greater thickness. In addition, the application of adhesive can locally stiffen the tear-open packaging.

Often, therefore, the tearing process for opening a tear-open package is initiated in the immediate vicinity of the adhesive application which connects the closure section to the connection section. Thus, the user opening the tear-open package can overcome the adhesive overlap closure with power and skill. Once the closure portion is separated from the connecting portion, the further opening of the tear-open packaging is generally straightforward.

In undesirably many cases, the adhesion of the closure portion to the adhesive is greater than the internal cohesion of the fibrous layer. It then comes when opening the tear-open to an undesirable effect: the fibrous layer separates in the thickness direction, parallel to the extension of their layer surface, in two mutually substantially parallel fiber-containing partial layers. A first partial layer remains bonded to the adhesive. A second sub-layer remains associated with the at least one further material layer that the user who is opening the tear-open package has grasped for this purpose.

The result is that the tear-open package is not actually opened but only a portion of the tear-open packaging is removed, while a portion of the tear-open package closer to the packaged product remains in place. This remaining part of the Aufreißverpackung, which is much thinner than the original tear-open packaging because of the described layer separation of the fibrous layer, can be removed later with little effort. However, this subsequent removal is troublesome and involves the risk of contamination of the packaged product and / or soiling of the user, who, in order to fully expose the packaged product, grasp by hand the remaining portion of the tear-open packaging which is closest to the packaged product, and must remove.

It is therefore an object of the present invention, the Aufreißverpackung of the type mentioned further such that the intended separation of the closure portion of the connecting portion of the described layer separation of the fiber-containing layer avoided and so easy opening of the Aufreißverpackung in preferably one operation is possible.

This object is achieved by a Aufreißverpackung of the type mentioned, in which the fibrous layer has a material weakening, which is located in the tear behind the closure portion and extends orthogonal to the direction of tearing, along the material weakening fibers of the fibrous layer are severed.

By "predominantly orthogonal to the tearing direction" is meant that a progression along the weakening course of the material weakening means, to a greater extent, a progression orthogonal to the tearing direction than a progression in the tearing direction. It should not be excluded that the weakening of the material weakening also has a component in the tear, but the component orthogonal to the tearing direction for at least half of the longitudinal extent of the material weakening, preferably for its entire longitudinal extent, be greater than the component in the tearing direction.

The described ply separation, when it happens, occurs at an unpredictable point in the thickness direction of the fibrous layer. However, both partial layers resulting from such a layer separation are in turn continuous fibrous layers, although the partial layer remaining attached to the adhesive will also have scarcely predictable edge courses with a predominant development component in the tear-open direction.

By introducing the material weakening in the fiber-containing layer with thereby severed fibers of the fiber-containing layer, a force transmission in the fiber-containing layer in the tear direction over the material weakening time is considerably more difficult. Even if a layer separation takes place in the fiber-containing layer in the area of the adhesive application on the closure section, it ends in the tear-open direction during the further opening process of the tear-open package on the weakening of the material which is predominantly orthogonal to the tearing direction. Because of the severed fibers, only minor forces in the fiber-containing plane can be transferred beyond this weakening of the material than would be required to continue the separation of the fiber-containing layer into two partial layers. If the weakening of the material projects from a layer surface facing the adhesive in the direction of the thickness of the fibrous layer into that thickness coordinate into which the layer separation takes place, no transmission of force is possible at all in the part layer remaining connected to the adhesive. This is then simply interrupted by the material weakening. An occurred ply separation of the fiber-containing layer therefore ends at the material weakening, so starting from the weakening of the material Aufreißverpackung safely opened in the tear and thus the packaged by Aufreißverpackung good can be made available safely and without rework.

Unlike the prior art, the present material weakening in the packaging material sheet blank does not serve to guide a desired remainder along a desired course, but to avoid propagation of ply separation of the fibrous layer.

The packaging material sheet blank may have more than said two layers: fibrous layer and at least one other layer. For the most secure packaging of a good through the presently discussed tear-open packaging with the greatest possible avoidance of an impact of the environment outside the tear-open on the packaged Good, the material weakening is preferably formed only in the fibrous layer. As a rule, only the fiber-containing layer is threatened by the ply separation described.

If the packaging material sheet blank has more than one fiber-containing layer, it is preferred that the fiber-containing layer closest to the adhesive application in the closure section be provided with the material weakening.

Likewise, for the greatest possible avoidance of an effect of environmental influences outside of the tear-open packaging on the packaged product, it is advantageous if the material weakening does not completely penetrate the fibrous layer in its thickness direction. Thus, even a thickness portion of the fibrous layer remains intact and unharmed by the material weakening. However, it should not be ruled out in principle that the fibrous layer has separate fibers throughout its thickness due to weakening of the material, although this is not preferred.

The penetration depth of the material weakening in the thickness direction of the packaging material sheet blank required for preventing the spread of ply separation of the fibrous sheet depends on the nature of the fibrous sheet as well as the adhesive used for bonding the closure portion and the joint portion. With great certainty, the propagation of a ply separation in the tearing direction occurring in the closure section can be prevented if the material weakening extends in the thickness direction of the fiber-containing layers over more than one third of the thickness dimension of the fiber-containing layer. Even greater safety is achieved when the material weakening extends over at least two thirds of the thickness of the fibrous layer.

However, the deeper the weakening of material from a surface of the fiber-containing layer protrudes into it in the thickness direction, the sooner the weakening of the material becomes a weakening of the tear-open package as a whole. Here is a meaningful compromise to find. A very secure prevention of spread of ply separation can be achieved in almost all cases when the material weakening does not extend beyond four-fifths of the thickness of the fibrous ply. A still safe prevention with even stronger shielding effect of the fibrous layer also in the field of material weakening can be achieved if the material weakening extends over not more than three quarters of the thickness of the fibrous layer.

The fiber-containing layer can basically be any fibrous layer. Due to the low basis weight with very good food compatibility and strong material connection along the orthogonal to the thickness direction layer extension, the fibrous layer is preferably a paper layer. As a result of the material weakening, a layer of uncoated paper can be used as the fibrous layer, since the paper does not require any coating in order to become more resistant to layer separation. Uncoated paper is not only cheaper, but also safe to use as a food packaging, compared to coated paper.

Preferably, the weakening of the material is a line-like formation, that is to say a quasi-two-dimensional design having a first dimension in the thickness direction of the fibrous layer and with a second dimension along the direction of extent of the material weakening. The course of the material weakening in the surface of the fiber-containing layer can be curved several times, but is preferably straightforward for reasons of simplest possible production. Particularly preferably, the material weakening runs along the machine direction of the flat packaging material from which the packaging material sheet blank is produced.

Although it should not be ruled out that the material weakening intermittently runs along its weakening course, ie the weakening of material is interrupted at a plurality of points by unattenuated sections of the fiber-containing layer, the material weakening is longitudinally as secure as possible in preventing the spreading of a layer separation of the fibrous layer in the tearing direction a weakening course continuous incision. An incision separating fibers in the fiber-containing layer can be produced with any suitable tools, for example with a laser beam or with a mechanical blade, in particular with a rolling blade rotating about a roll axis.

In general, it is also to be assumed that, due to the adhesive action of the adhesive used to connect the closure section and the connecting section, when the tear-open packaging is opened, a ply separation in the fiber-containing layer takes place on the closure section. In order to prevent as early as possible the ply separation occurring in the region of the adhesive application from propagation in the tearing direction, the material weakening is preferably located in a region which does not extend more than 10 mm, preferably not more than 5 mm, from the closure section in the tearing direction extends more than 3 mm away. The closure section is at least the region of the section of the packaging material sheet blank to be separated when being opened from the connection section, at least the region wetted by the adhesive.

Likewise preferably, the weakening of the material in the tear-open direction is provided at a distance different from zero from the closure section, ie, from the application of adhesive, since bridging the weakening of the material by the application of adhesive could completely wipe out the advantageous effect of weakening the material.

Not only should the weakening of the material be arranged to prevent spread of ply separation in the tearing direction at the aforesaid preferred placement location relative to the adhesive application or closure portion. Since a ply separation that occurs once propagates along the tear direction with unpredictable edge course, it is further preferred for secure prevention of such spreading that the material weakening projects beyond the adhesive application in the closure section in the direction of the longitudinal extent of weakening and adhesive application in at least one direction, preferably on both sides. Then it does not matter for a successful prevention of the spread of a ply separation on the edge course, since this will always run into the material weakening in propagation in the tear. The material weakening therefore preferably projects beyond the adhesive application along its longitudinal direction by more than its distance in the direction of tear from the application of adhesive. To be on the safe side, the locally greatest distance of material weakening from a longitudinal end region of the adhesive application should be used.

In the prior art, one often tries to minimize the effect of ply separation of the fibrous layer by applying the adhesive only intermittently along an application track. Thus, along the application track of the adhesive, locations where adhesive is present alternate with locations where there is no adhesive. Thus, the ply separation and its propagation is not limited in the extension surface of the fiber-containing layer orthogonal to the tearing direction to areas in which said adhesive points are set. On the one hand, this does not prevent the spread of the ply separation of the fiber-containing layer. On the other hand, the overlap of connecting portion and closure portion along the application track of the adhesive is not or at least not securely sealed over the entire length.

By contrast, with the material weakening discussed herein, the spread of ply separation of the fibrous layer can be safely prevented, regardless of how the adhesive is applied and which adhesive is used. Therefore, advantageously, the adhesive may be applied continuously in a direction predominantly orthogonal to the tear direction. Thus, a gap in the region of the overlap between connecting portion and closure portion can be completely closed and sealed by continuous application of adhesive.

In principle, it should not be ruled out that a further material layer is provided between the fibrous layer and the adhesive application. Preferably, however, the fibrous layer forms an exposed surface on the inside of the tear-open package facing the packaged product. In this case, the adhesive wets the fiber-containing layer. Especially when using uncoated paper as the fibrous layer adhesive can penetrate into the fibrous layer itself and thus ensure a high security against leaks.

Basically, it should not be excluded that only the closure portion is formed on the packaging material sheet blank and that the connecting portion is provided on a separately formed part of the tear-open packaging. Thus, for example, the connecting portion may be formed on a container made of plastic or cardboard and the packaging material sheet blank only cover an opening of this container. Preferably, however, for the fastest possible, simple, inexpensive and secure packaging of a good to be packaged, the closure portion and the connecting portion are integrally formed in the tear-open direction at a distance from one another on one and the same packaging material sheet blank. In this case, the closure portion abuts the finished tear-open package with the inside of the packaging material sheet blank on the outside thereof at the connection portion. The packaging material sheet blank is preferably adhesively bonded "inside" against "outside" by the adhesive.

In principle, therefore, it can also be considered that with a separation of the closure section from the connecting section, an opening on the tear-open packaging is sufficiently opened and a content of the tear-open packaging is made accessible. To ensure hermetically sealed packaging of the packaged goods through the tear-open packaging, the packaging material sheet blank is preferably designed or / and determined so that its material connection is destroyed when the tear-open packaging is opened substantially in the tear-open direction. The destruction of the material connection is usually carried out by propagation of a crack in the tear. Also, the propagation of two substantially parallel spaced apart cracks is a destruction of a material context in the sense of the present invention.

A preferred embodiment of the tear-open packaging is a wrapping package which completely surrounds a virtual winding axis in the circumferential direction. This may be, for example, a conical topping bag, such as is used to package ice cream filled conical waffles. In the case of a conical topping bag, the propagation of only a crack is sufficient to destroy the material context, since usually a region of the tear-open packaging closer to the conical tip remains as grip protection on the packaged product and only an area of the tear-open packaging further away from the conical tip the conical tip closer area is separated to expose the packaged property and make accessible ..

The at least one further layer preferably comprises or is an aluminum layer which serves as a water vapor and oxygen barrier. The packaging material sheet blank is therefore preferably an aluminum-paper composite. Other layers may be provided, such as a print for applying product information on the tear-open packaging. Such printing is usually applied to the farther than the fibrous layer from the packaged Good located aluminum layer or generally metal layer, since it is visible only on this location for the user from the outside. As a further layer, a protective layer for protecting the printing on the outside of the metal layer, in particular aluminum layer may be applied, such as a paint or a plastic layer.

Another advantage of the present disclosure tear-open packaging with the described material weakening is that the material weakening can serve as a kind of primary packaging seal and indicates the unmanipulated, intact Erstverpackungszustand the tear-open packaging.

In 1 An embodiment of a tear-open package according to the present invention is generally included 10 designated. It is formed as a wrapping in a 2 in the processing illustrated packaging material sheet blank 12 ,

The packaging material sheet blank 12 is to form the tear-open package 10 in the form of a conical topping cone around a cone axis K wound. In the circumferential direction around the cone axis K opposite end areas 12a and 12b the packaging material sheet blank 12 overlap to the possibility of a closure of the tear-open packaging 10 to offer.

A closure section 14 in the end area 12a the packaging material sheet blank 12 overlaps radially outside relative to the cone axis K a connection section 16 in the tear-open direction T opposite end region 12b the packaging material sheet blank 12 , Radial between these sections 14 and 16 is glue 18 applied, which the closure section 14 Adhesive with the connecting section 16 combines. As an adhesive 18 For example, a so-called "hotmelt" is used. However, any other suitable adhesive can be used.

The adhesive 18 is continuously applied along an application track A, to one between the closure portion 14 and the connection section 16 existing radial gap as hermetically as possible against the outside environment of the tear-open packaging 10 to close.

The packaging material sheet blank 12 extends from a first margin 12a1 approximately as circular sector up to a second margin 12b1 ,

A part-circular opening edge 12c1 connects the two margins 12a1 and 12b1 , The opening edge 12c1 can on the finished tear-open packaging 10 in the form of the conical top cone to the cone axis K folded over. Under the Umfalzung 20 can in a conventional manner a cover plate 22 which is that of the wound packaging material sheet blank 12 surrounding conical packaging space axially.

In doubt, as a closure section 14 and connecting section 16 those sections of the packaging material sheet blank 12 in its end areas 12a and 12b apply which of the adhesive 18 are wetted.

The tear-open packaging 10 can be in the circumferential direction around the cone axis K along the tear direction T be torn up. Here, usually, a crack propagating approximately along the circumferential direction is cut in the packaging material sheet 12 introduced so that along this crack one of the cone tip 24 remote part 26 the tear-open packaging 10 Will get removed. The tear direction T is preferred on the conical tip bag 10 the circumferential direction. In the handling of the packaging material sheet blank 12 The tearing direction can and will be mobile.

To facilitate the opening of the tear-open package 10 is at the radially outer end region 12a a handle bottle 28 formed, which without intermediate arrangement of adhesive only on an underlying portion of the packaging material sheet blank 12 rests and thus easily gripped by the user with two fingers, from the underlying portion of the packaging material sheet blank 12 lifted and to initiate the tear-open packaging 10 opening crack in the tear direction T can be moved.

In such tearing of the tear-open packaging 10 Not only is it necessary to use the force required for crack initiation and crack propagation, but at the beginning of the tearing movement, it is also the adhesive applied 18 overcome applied closure force.

The packaging material sheet blank 12 comprises a layer material with one in the finished state of the packaging 10 closer to the cone axis K lying paper layer 30 and with one on the finished packaging 10 further outside aluminum layer 32 , On the aluminum layer 32 can still further out another location 34 be applied, for example, a printing or a plastic layer, such as PET or other plastic.

In the example shown immediately the paper layer 30 which has an inside surface of the tear-open package 10 forms, when closing the tear-open packaging 10 in the closure section 14 of glue 18 wetted.

When tearing the tear-open packaging 10 can therefore, if the adhesive force of the adhesive 18 in interaction with the paper layer 30 is greater than the internal cohesion of the paper layer 30 , a ply separation of the paper layer 30 occur. This will be the paper layer 30 approximately parallel to their layer surfaces in two partial layers torn, namely a partial position 30 ' which adheres to the adhesive 18 remains, and a partial position 30 " , which with the aluminum layer 32 remains connected. A fictitious possible dividing line 35 between the described partial days 30 ' and 30 " is in 3 indicated by dashes. Incidentally, such a layer separation can also occur if the paper layer 30 not immediately with glue 18 wetted, but the Adhäsivkraftwirkung of the adhesive 18 on the directly related to him position and the connecting force effect of the adhesive 18 connected to the paper layer 30 are larger than the inner cohesion of the paper layer 30 , In this case, delamination requires the adhesive 18 connected position of the paper layer 30 a greater force than the ply separation described above within the paper ply 30 ,

Without further measures, such a layer separation spreads along the tear direction T from, for example, because together with the aluminum layer 32 the ones with this situation 32 connected paper-part-layer 30 " from the adhesive 18 remaining paper-part-layer 30 ' peeled off in the course of the tearing movement. That from the tear-open packaging 10 packaged product remains despite tearing by the adhesive 18 remaining paper-part-layer 30 ' at least partially covered.

To avoid such undesirable obstruction of an opening operation of the tear-open packaging is in the paper layer 30 a linear material weakening 36 introduced along which fibers 37b in the paper layer 30 are severed. The material weakening 36 is therefore a disturbance of the material context in the paper layer 30 , This distinguishes the material weakening 36 from a merely impressed depression. The material weakening 36 was present in the present example, as a straight incision by means of a mechanical blade in the of the aluminum layer 32 distant layer surface 30a in the thickness direction D the paper layer 30 brought in. Likewise, the material weakening 36 however, by a laser beam thermally from the ply surface 30a in the thickness direction D the paper layer 30 be introduced.

The material weakening 36 is in 2 shown in dotted lines, as they are on the view of the viewer 2 opposite side of the packaging material sheet blank 12 and at least the aluminum layer 32 and optionally the further location 34 is covered.

The material weakening 36 is from the layer surface 30a out in the thickness direction D not over the entire thickness of the paper layer 30 introduced, but extends in the thickness direction D only over about preferably two-thirds to four-fifths of the thickness dimension of the paper ply 30.

Thus, there is a high probability that occurs during tearing layer separation of the paper layer 30 in a thickness range of the paper layer 30 in which the weakening of the material takes place 36 extends so that the material weakening 36 a spread of ply separation in the tear T interrupts. Even if a ply separation of the paper layer 30 in the small undamaged thickness range between the material weakening 36 and the aluminum layer 32 with not severed fibers 37a runs, is due to the residual strength of the paper layer remaining there 30 about the material weakening 36 no sufficient force in the paper layer 30 , Especially in a possibly incurred on the adhesive 18 adhesive paper-part-layer 30 ' , transferable, the spread of the ply separation over the material weakening 36 would allow out.

In addition, the material weakening 36 whose weakening direction V is substantially parallel to the application track A of the adhesive 18 runs, serve as a first-opening seal, which indicates whether the tear-open packaging 10 Original still unlocked or already opened and closed again.

The attenuation course V of material weakening 36 preferably runs orthogonal to the tearing direction T , so one along the tear direction T Spreading layer separation with certainty in the material weakening 36 into it.

The material weakening 36 is also starting from the part-circular side edge 12c1 out to the future Konusspitze 24 towards the paper layer 30 the packaging material sheet blank 12 brought in. At her the future Konusspitze 24 closer longitudinal end surmounted by the material weakening 36 at least the intended tear-open area of the section intended for separation 26 , Alternatively, the material weakening 36 from the margin 12c1 to the margin 12b1 are enough to make sure each one in the closure section 14 occurring layer separation during propagation along the tear direction T the material weakening 36 reached and ends there.

The adhesive 18 is in the tear direction between the grip tab 28 and the material weakening 36 applied.
