Description

Cellulosic packaging and opening method

The invention relates to a packaging comprising a tray made of cellulose-containing flat material and a lid, the tray and the lid enclosing an interior of the packaging, the tray having a first side wall on which a first sealing edge extends away from the interior along a first folded edge is angled on the outside, and wherein the lid is glued to the first sealing edge. Such a packaging is known, for example, from EP 2 085 315 B1.

In the known packaging, a flap serving to open the packaging is separated from the shell, which flap has an outwardly angled pull tab which adjoins a plastic part forming the lid and is peeled off. An outwardly protruding handle tongue is hinged to the pull tab.

The use of plastic - in the case of the packaging known from EP 2 085 315 B1 for the lid - is increasingly viewed as problematic for ecological reasons, in particular with regard to aspects of disposal or recycling.

An airtight packaging is known from WO 01/66425 A1, which has perforation lines that are offset from one another. A pouring opening of the packaging can thus be opened.

A package, for example for toothbrushes, is known from US Pat. No. 2,289,236 A, which has a locking mechanism at each end. If the packaging is unlocked at both ends, the packaging can be opened.

From DE 195 32 162 A1 a packaging made of cardboard has become known, which is composed of a front wall and a rear wall. In the front wall, a container is formed which has a perforation line in the edge area to the rear wall. The packaging can be opened along the perforation line.

Object of the invention

It is an object of the invention to provide an environmentally friendly and economically producible packaging which can be opened in a defined manner in a simple manner. Description of the invention

This object is achieved according to the invention by a package according to claim 1. In further aspects, the invention relates to a container according to claim 10, a method for opening a package according to claim 11 and a method for providing an object according to claim 13.

Packaging according to the invention

According to the invention, a packaging with at least one perforation is provided which has a weakening, the reduction of the bending resistance, of the cellulosic material of the packaging in the area of the perforation or the perforation line.

Perforation in the sense of the packaging according to the invention, the container according to the invention and the method for packaging and / or for opening the packaging according to the invention is to be understood as a material weakening, the perforation being a score line that partially cuts through the cellulose-containing material starting from one side or the score line is formed by cracks on both sides of the cellulosic material. The cracks are spaced from one another.

In a further embodiment, the perforation is a cutting line with notches, the notches being distributed uniformly and / or unevenly.

The perforation is alternatively designed as a groove which loosens the cellulose-containing material, in particular the fiber structure, and thereby creates a material weakening in the area of the perforation line.

Mechanical kinking or the folding of the cellulose-containing material in the area of the folded edge is a perforation in the sense of the packaging according to the invention. All of the perforation shapes described can be formed individually or in combination on the packaging according to the invention and produce a material weakening in the area of the perforation line.

The packaging is used in particular for packing piece goods, i. H. in other words, individual objects. An object to be packaged can be a toothbrush, for example. The packaging according to the invention is, however, basically suitable for packaging a wide variety of objects. In particular, the packaging can also be designed for packaging bulk goods. The packaging is preferably designed in the form of a blister pack (transparent packaging). This makes it possible to view the packaged goods without opening the packaging.

The packaging has a tray made of cellulose-containing flat material and a lid. Cellulose-containing flat material can be easily processed and recycled. In particular, the unfolding can be efficiently automated. The shell typically forms a hollow body that is open on one side. The tray and the lid enclose an interior space of the packaging. For this purpose, the lid is arranged on the shell or placed on the shell. The cover can be flat. In particular, the cover can extend in one plane. The goods to be packaged can be arranged in the interior. The cellulose-containing flat material can be coated or impregnated on one or both sides, in particular water-repellent. The coating or impregnation is preferably biodegradable.

The shell has a first side wall. The first side wall delimits the interior of the packaging. On the first side wall, a first sealing edge is angled away from the interior along a first folded edge. In other words, the first sealing edge protrudes outward from the first side wall. The first sealing edge forms an edge strip of the desired width. The first sealing edge and the first side wall typically each extend in one plane. The first edge of the seal and the first side wall can (on the outside with respect to the interior) enclose an angle of at least 60 °, in particular at least 75 ° and / or at most 145 °, in particular at most 120 °. In a preferred embodiment, the first sealing edge and the first side wall can enclose a right angle.

The lid is glued to the first sealing edge. The bond can be implemented as a heat seal, in particular with blister varnish. For gluing to the first sealing edge, the cover can have a section (area) which covers the first sealing edge. The lid and the first sealing edge can have an outer contour that ends essentially flush with one another. The lid preferably protrudes slightly, in particular by a maximum of 2 mm, preferably by a maximum of 1 mm, over the first sealing edge.

Since the first sealing edge and the lid protrude away from the interior, they can be grasped in a simple and comfortable manner with fingers, in particular the thumb and forefinger of one hand. A free length of the first sealing edge and the lid can be at least 1 cm, preferably at least 1.5 cm.

According to the invention, it is provided that a perforation is formed on the first folded edge for jointly tearing off the first sealing edge and the portion of the cover that is glued to it from the first side wall. The perforation extends at least in sections along the first folded edge. The perforation makes it easier to open the packaging. As a result of the perforation, in particular a force required for opening that is consistently low over a large number of packagings produced can be established. To open the packaging, the outwardly protruding first sealing edge and the area of the lid attached to it can be gripped and torn off together from the first side wall. For this purpose, the first sealing edge and the glued-on section of the lid are moved away from the first side wall, so that the flat material of the tray is severed along the perforation. The shell has a second side wall along with a second folded edge a second sealing edge is angled away from the interior space. The second side wall also delimits the interior of the packaging. The lid is glued to the second sealing edge. As with the first sealing edge, the second sealing edge forms an edge strip with a width that is permanently glued to the lid. As a result, the packaging can be closed particularly tightly. To open the packaging, the lid can be pulled off the second sealing edge after the first sealing edge has been torn off from the first side wall. The tearing off of the first sealing edge together with the glued-on section of the lid and the detachment of the lid from the second sealing edge can take place particularly comfortably in a single movement and without reaching around.

In a particularly preferred embodiment, the perforation is formed with perforation openings which completely penetrate the flat material of the shell. As a result, the packaging can be opened with particularly little effort. Such a perforation can also be produced particularly easily.

Alternatively or additionally, it can be provided that the perforation is formed with depressions in the flat material of the shell, with a remaining thickness of the flat material at the depressions being further reduced compared to the folded edge. The depressions do not completely penetrate the flat material of the shell. In other words, the flat material is formed continuously along the perforation. In this way, the interior of the packaging or the packaged goods can be protected particularly effectively against soiling, for example from dust and / or liquids. In the area of the depressions, in particular laterally next to the depressions, fibers, in particular cellulose fibers, of the flat material can be severed. As an alternative or in addition, the flat material can be compressed below (viewed in the thickness direction) of the depressions.

The perforation on the first folded edge preferably extends over the entire length of the first folded edge. This makes it easier to tear off the first one Seal edge from the first side wall. In particular, when opening the packaging, it is not necessary to pay attention to the end of the folded edge at which the perforation is formed. Rather, the opening of the packaging can be initiated from both ends of the folded edge and conveniently continued with the tear propagation resistance of the perforated folded edge essentially remaining the same.

A basic element of the lid can consist of cellulose-containing flat material. This is considered beneficial in terms of environmental protection. The cover can be formed as a whole by the base element made of cellulose-containing flat material. Alternatively, an additional element of the cover, in particular a closure element for a viewing window, can be attached to the base element. The additional element can also consist of a cellulose-containing flat material. The cellulose-containing flat material of the shell, the base element and the additional element can each be of the same type. Alternatively, a different type of cellulose-containing flat material can be provided for the shell, the base element and / or the additional element.

The first and second side walls are typically adjacent to one another. The first and second side walls are preferably connected to one another via an adhesive flap. This can increase the stability of the tray or the packaging. The second sealing edge and the second side wall typically each extend in one plane. The second sealing edge and the second side wall can (on the outside with respect to the interior) enclose an angle of at least 60 °, in particular at least 75 ° and / or at most 145 °, in particular at most 120 °. In a preferred development, the second sealing edge and the second side wall can enclose a right angle. Typically, the tray has two second side walls and each a second sealing edge angled outwards.

The shell can have a third side wall, which preferably adjoins the second side wall or the second side walls, and along which a third folded edge, a third sealing edge is angled away from the interior space to the outside, with which the lid is glued. The third sealing edge also forms an edge strip with a strip width that is suitable for resting on and for gluing the lid to the tray. The third sealing edge and the third side wall typically each extend in one plane. The third sealing edge and the third side wall can (on the outside with respect to the interior) enclose an angle of at least 60 °, in particular at least 75 ° and / or at most 145 °, in particular at most 120 °. In a preferred development, the third sealing edge and the third side wall can enclose a right angle. The third side wall also delimits the interior of the packaging. In particular, the interior of the packaging can be delimited circumferentially by the first side wall, the two second side walls and the third side wall.

The shell typically has a base which delimits the interior space on a side facing away from the lid. The side walls can each be angled from the floor along a fold line. The base and the first, second and / or third side wall or side walls typically each extend in one plane. The bottom and the first, second and / or third side wall or side walls can enclose (on the inside with respect to the interior) an angle of at least 60 °, in particular at least 75 ° and / or at most 145 °, in particular at most 120 °. In a preferred development, the base and the first, second and / or third side wall or side walls can enclose a right angle.

A strength, in particular a peel strength, of the gluing of the lid to the second sealing edge is preferably greater than a strength of the material of the lid and / or the shell. It can thereby be achieved that when the cover is pulled off the second sealing edge, the adhesive connection between the cover and the second sealing edge is retained and instead a separation takes place in the material of the cover or the shell. This has proven to be advantageous with regard to the opening behavior of the packaging, in particular the force required to open it. Alternatively or additionally, it can be provided that a perforation is formed on the second folded edge for tearing off the second sealing edge together with the portion of the cover glued to it from the second side wall. The perforation on the second folded edge can make it possible to open the packaging with a particularly low expenditure of force. The perforation on the second folded edge can, like the perforation on the first folded edge, be designed with continuous perforation openings or with depressions. The perforation on the second folded edge extends at least in sections along the second folded edge. Typically, the perforation on the second folded edge is formed in a region of the second side wall adjoining the first side wall.

The lid and / or the shell can have at least one viewing window. The viewing window allows you to look into the interior of the packaging without opening the packaging. The viewing window can be formed by a recess in the material of the shell or the cover. This simplifies the manufacture of the packaging. The viewing window is preferably closed by a transparent closure element. As a result, the goods received in the interior of the packaging can be effectively protected from contamination, in particular from dust and / or liquid. The closure element can consist of a cellulose-containing flat material, for example a bio-based film.

It is advantageously provided that a suspension recess breaks through the first sealing edge and the portion of the lid that is glued to it. By means of the suspension recess, the packaging can be hung in a simple manner, in particular for the presentation of the packaged goods or the packaging. Furthermore, the hanger recess can make it easier to hold the first sealing edge and the portion of the lid glued to it when torn from the first side wall. The gluing of the lid to the first sealing edge typically extends circumferentially, preferably continuously circumferentially, around the suspension recess. This can reduce the stability of the Increase packaging in the area of the suspension recess and, in particular, help prevent the suspension recess from tearing or tearing through.

An insert for fixing an object that can be received in the packaging can be arranged in the shell. The insert can help prevent damage to the item and / or the packaging. Preferably, the insert consists of a cellulose-containing flat material.

Container according to the invention

The scope of the present invention also includes a container with a packaging according to the invention as described above and with an object that is received in the packaging. With the container, the advantages of the packaging according to the invention can be used for the packaged object, in particular its presentation for sale. The object is typically designed as a piece goods. The object can be a toothbrush, for example. In principle, however, there are no restrictions with regard to the object as long as it is suitable, in particular with regard to its size and nature, for packaging with cellulose-containing flat material. The size of the object, in particular a largest dimension, is typically in the centimeter to decimeter range; in special cases also in the millimeter range. The container can contain a single item. Alternatively, it can be provided that the container comprises several (typically up to 10 or 20, in special cases also more) separate objects in a single packaging according to the invention described above.

The container can contain several objects in the form of bulk goods, which are contained in the packaging. If the perforation on the first and / or the second folded edge with continuous perforation openings is formed, a smallest grain size of the bulk material is preferably essential, in particular at least 5 times, as large as a largest dimension of one of the perforation openings. The grain size of the bulk material can in particular be in the millimeter range.

Inventive opening procedure

A method for opening a package also falls within the scope of the present invention. The packaging has a tray made of cellulose-containing flat material and a lid. The tray and the lid enclose an interior space of the packaging. The shell has a first side wall on which a first sealing edge is angled away from the interior space along a first folded edge. The shell also has a second side wall on which a second sealing edge is angled away from the interior space along a second folded edge. The lid is glued to the first sealing edge and to the second sealing edge. A perforation is formed on the first folded edge. The packaging can have further features of the packaging according to the invention described above.

The method comprises the steps of a) jointly tearing off the first sealing edge and the portion of the lid glued to it from the first side wall along the perforation on the first folded edge, b) pulling the lid off the second sealing edge.

Step a) serves to prepare for step b). As a result of the perforation on the first folded edge, the tearing in step a) can be carried out easily, in particular with little effort. Furthermore, a defined course of the crack can be specified by means of the perforation. The tearing off of the first sealing edge and the portion of the lid that is glued to it from the first side wall in step a) is basically carried out without separating the first sealing edge from the lid. In other words, when the first sealing edge and the portion of the lid glued to it are torn off from the first, they remain Side wall, the first sealing edge and the lid are glued together. To carry out step a), the first sealing edge and the area of the lid glued to the first sealing edge are typically gripped by fingers of one hand, in particular the index finger and thumb, and pulled away from the first side wall. The packaging can be grasped by a second hand in the area of the shell or around the interior.

The packaging is opened further, in particular completely, by step b). When performing step b), the interior is released. The preparatory step a) enables the lid to be detached from the second sealing edge in a particularly convenient manner. By tearing off the first sealing edge together with the glued-on portion of the lid from the first side wall, a partially open configuration of the packaging is automatically obtained, from which the further detachment of the lid from the second sealing edge, in particular by peeling, can be carried out particularly easily. Steps a) and b) can advantageously be carried out in a single, uniform movement. Step b) can begin before step a) is completed. In other words, the cover can already be detached from the second sealing edge in some areas before the first sealing edge and the section of the cover that is glued to it have also been completely torn off from the first side wall.

The shell and / or the lid preferably contain fibers, in particular cellulose fibers, which are torn in step b). In other words, the fibers are destroyed or severed in step b). The tearing of the fibers has proven to be advantageous with regard to the opening behavior of the packaging. In order to ensure that the fibers are torn in step b), a strength, in particular a peel strength, of the gluing of the lid to the second sealing edge can be greater than a strength of the material of the lid and / or the shell. Provision method according to the invention

Finally, a method for providing an object falls within the scope of the present invention. The method comprises the steps

A) Providing a blank made of cellulose-containing flat material and a lid,

B) producing a first folded edge with a perforation in the blank, wherein the first folded edge delimits a first side wall from a first sealing edge, and producing a second folded edge in the blank, wherein the second folded edge delimits a second side wall from a second sealing edge,

C) unfolding a shell from the blank,

D) placing the item in the tray,

E) gluing the lid to the first and second sealing edge of the bowl,

F) Opening the packaging, in that in a step a) the first sealing edge is torn off from the first side wall together with the portion of the lid glued to it along the perforation on the first folded edge and in a step b) the lid is pulled off the second sealing edge . Typically, in a step G), the object is removed from the shell of the opened package.

By means of steps A), B), C) and E), a packaging according to the invention described above can be produced with a first and a second side wall, each with a first and second sealing edge. The packaging obtained through steps A), B), C) and E) can have further features of the packaging according to the invention described above. In particular, it can be provided that in step B) perforation openings that completely penetrate the blank are produced. Alternatively, it can be provided that in step B) depressions are produced in the flat material of the blank along the folded edge. The first and second folded edges can be embossed into the blank. The shell can be unfolded in step C) manually, partially automatically or preferably fully automatically (by machine). Typically, the first and second side walls connected to one another, for example glued to one another by means of an adhesive flap. Between steps C) and D), an insert for fixing the object can be inserted into the shell.

Step D) ensures that the object is arranged in the interior of the closed packaging. Furthermore, an above-described container according to the invention can be obtained through step D). The container can have other features described above. After step E) has been carried out, the object is enclosed by the packaging. The packaging can in particular protect the object from soiling and / or damage. The lid can be glued to the first and second sealing edges in step E) by heat sealing, in particular using blister varnish. The gluing of the lid to the first and the second sealing edge in step E) can be carried out manually, partially automatically or preferably fully automatically (by machine).

In step F) the packaging is opened. After opening the packaging, the object can be removed from the packaging in a step G). The packaging is opened in step F) by means of the method according to the invention described above. The advantages of the opening method according to the invention can thus be used for the provision of the object, in particular with regard to the removal of the packaging from the object. When the lid is pulled off the second sealing edge in step b), fibers, in particular cellulose fibers, of the tray and / or of the lid are preferably torn.

Further features and advantages of the invention emerge from the description and the drawing. According to the invention, the features mentioned above and those detailed below can be used individually or collectively in any desired, expedient combinations. The embodiments shown and described are not intended to be an exhaustive list understand, but rather have an exemplary character for describing the invention.

FIG. 1 shows a package 10. In the configuration shown in FIG. 1, the package is in a partially opened state. An object 12 is received in the packaging 10. The packaging 10 and the object 12 together form a container 14. The object 12 is shown here symbolically as an approximately cylindrical body.

The packaging 10 has a tray 16 and a lid 18. The shell 16 is unfolded from a cellulose-containing flat material, for example paper or cardboard. The cover 18 has a base element 20, which here also consists of cellulose-containing flat material, for example white paper or cardboard. Two viewing windows 22 are formed in the base element 20. The viewing windows 22 can be closed by a transparent closure element (not shown in detail). The closure element can consist of a transparent flat material, for example a bio-based film.

The shell 16 and the lid 18 (in the closed state of the packaging 10) together enclose an interior space 24 of the packaging 10. The object 12 is arranged in the interior space 24. In addition, an insert 26 for fixing the object 12 can be provided in the interior space 24.

FIG. 2 shows the packaging 10 in a perspective view with a view of the shell 16. In FIG. 2, the packaging 10 is shown in the closed state.

The shell 16 is designed here essentially in the shape of a cuboid. The shell 16 has a bottom 28. Adjacent to the bottom 28 are a first Side wall 30, two second side walls 32 and a third side wall 34 (covered in Figure 2). The side walls 30, 32, 34 are each divided off from the base 28 by a fold line 35 or angled at the fold line 35 relative to the base 28, here by 90 ° in each case.

The shell 16 has a first sealing edge 36. The first sealing edge 36 is angled along a first folded edge 38 with respect to the first side wall 30. The first sealing edge 36 projects outward from the interior space 24 away from the first side wall 30.

The shell 16 has two second sealing edges 40, one of which is covered in FIG. The two second sealing edges 40 are each developed along a second folded edge 42 opposite the respectively assigned second side wall 32. The two second sealing edges 40 each protrude from the interior space 24 outwardly away from the second side walls 32.

The shell 16 can have a third sealing edge (hidden in FIG. 2). The third sealing edge is angled along a third folded edge (also covered) with respect to the third side wall 34. The third sealing edge protrudes from the interior space 24 outwardly away from the third side wall 34.

The lid 18 is glued to the first sealing edge 36, the two second sealing edges 40 and the third sealing edge. The bond can each be designed as a heat seal. The adhesive bond is typically flat, in particular over the entire surface of the sealing edges 36, 40 facing the lid 18. A peel strength of the adhesive bond can exceed a corresponding strength of the materials of the shell 16 and the lid 18.

A perforation 44 is formed on the first folded edge 38. The perforation 44 extends here over the entire length of the first folded edge 38. In other words, the cellulose-containing flat material from which the shell 16 is unfolded is perforated along the first folded edge 38. The first folded edge 38 and the perforation 44 can have been made in the sheet material in a common operation.

The perforation 44 can be formed with through perforation openings 46, see FIG. 5. The perforation openings 46 penetrate the flat material of the shell 16 completely. Web 48 remain between the perforation openings 46. A height H 1 of the webs 48 can be reduced by embossing the first folded edge 38 compared to a thickness D 1 of the flat material of the shell 16.

Alternatively, the perforation 44 can be formed with depressions 50, see FIG. 6. Elevations 52 are formed between the depressions 50. A remaining thickness D2 of the flat material in the area of the depressions 50 is reduced compared to a thickness D3 of the flat material in the area of the elevations 52. The thickness D3 can correspond to a greatest thickness of the first folded edge 38. The thickness D3 is basically smaller than a thickness Dl of the flat material of the shell 16 on the other side of the folded edge 38.

A further perforation can also be formed along the second folded edge (s) 42, at least in sections (not shown in more detail). The further perforation can in particular be formed at the end of the second folded edge (s) 42 close to the first folded edge 38. The further perforation can be designed with through perforation openings 46 or with depressions 50; in this respect, reference is made to the description above.

The packaging 10 can have a suspension recess 54. The suspension recess 54 breaks through the first sealing edge 36 and the cover 18 in the area of their gluing. The hanger recess 54 is consequently bordered in two layers here.

To open the packaging 10, in a first step 102, see FIG. 7, the first sealing edge 36 is torn off from the first side wall 30 together with the portion of the lid 18 that is glued to it. The first edge of the seal 36 and the section of the cover 18 glued to it can for this purpose be moved away from the shell 16 in the direction of arrow 56, see FIG. 3. For this purpose, the first sealing edge 36 and the cover 18 are typically held clamped between the fingers of one hand (not shown).

In Figure 3, a partially torn state of the packaging 10 is shown. A region of the first folded edge 38 on the right in FIG. 3 was torn along the perforation 44, whereas a portion of the first folded edge 38 on the left in FIG. 3 is still intact. In other words, in this left part of the first folded edge 38 there is still a continuous material connection between the first sealing edge 38 and the first side wall 30 by means of the flat material of the shell 16.

To open the packaging 10 further, in a step 104, see FIG. 7, the lid 18 is pulled off the two second sealing edges 40, see FIG. 4. The movement of the first sealing edge 36 in the direction of the arrow 56 according to FIG . rather be deflected away from the shell 16 in their direction.

When the cover 18 is pulled off the second sealing edges 40, cellulose fibers (not shown in detail) of the cover 18 and / or the tray 16 can be torn. This tearing of cellulose fibers can be promoted by the fact that a (peel) strength of the gluing of the cover 18 to the shell 16 is greater than a corresponding strength of the material of the shell 16 or of the cover 18 58 of the original gluing of the second sealing edges 40 to the cover 18, portions of the torn cellulose fibers from the second sealing edges 40 on the cover 18 remain. Correspondingly, parts of the torn cellulose fibers from the lid 18 can also remain on the second sealing edges 40.

FIG. 8 shows a flow chart of a method 200 for providing an object 12, compare FIG explained below using the example of the packaging 10 or the container 14 described above.

First, in steps 202 and 204, respectively, a blank made of cellulose-containing flat material and a lid 18 are provided. In the course of the method 200, a shell 16 is obtained from the blank. For this purpose, in steps 206 and 208, respectively, a first folded edge 38 with a perforation 44 and a second folded edge 42 are introduced into the blank. The first folded edge 38 delimits a first side wall 30 of the shell 16 being created from a first sealing edge 36. The second folded edge 42 accordingly delimits a second side wall 32 of the shell 16 being created from a second sealing edge 40. Typically, a further, second folded edge 42 is also introduced into the blank in the cut 208, which delimits a further second side wall 32 of the shell 16 that is being created from a further, second sealing edge 40. Correspondingly, in the cut 208, a third folded edge can also be introduced into the blank, which separates a third side wall of the shell 16 that is being created from a third sealing edge. The blank can then be unfolded in a step 210 so that the shell 16 is obtained.

In an optional step 212, an insert part 26 can be inserted into the shell 16. In a step 214, an object 12 is placed in the shell 16. Alternatively, the insert 26 or a further, additional insert (not shown) can also be inserted into the shell 16 after inserting the object 12 in section 214.

After inserting the object 12 and possibly all the insert parts 26, in a step 216 the lid 18 is glued to the first sealing edge 36, the second sealing edge 40 or the second sealing edges 40 and optionally the third sealing edge. In this way, a closed packaging 10 or a container 14 with a closed packaging 10 in which the object 12 is arranged is obtained. The packaging 10 is then opened by means of a method 100 described above, see FIG. 7. Then, in a step 218, the object 12 can be removed from the opened packaging 10 or its shell 16. The object 12 can now be used for further purposes.
