Description

Packaging and opening method consisting of a cellulosic material

Technical Field

The invention relates to a package having a shell and a lid which are folded from a flat material containing cellulose, wherein the shell and the lid enclose an interior space of the package, wherein the shell has a first side wall at which a first sealing edge is bent away from the interior space along a first folding edge, wherein the lid is bonded to the first sealing edge.

Background

Such a package is known, for example, from EP 2085315B 1.

In the known packaging, a flap for opening the packaging is spaced apart from the housing, which flap has an outwardly bent pull-off tab which adjoins the plastic part forming the lid and is sealed in a peelable manner on the plastic part. An outwardly projecting handle tongue is hinged to the pull-open tab.

The use of plastics (in the packaging for lids known from EP 2085315B 1) is however viewed for ecological reasons as an increasing problem, in particular with regard to the removal of waste or recycling.

From WO 01/66425 a1, a gas-tight packaging is known, which has hole-like seam lines offset from one another. Whereby the pour opening of the package can be opened.

A package, for example for a toothbrush, is known from US 2289236 a, which has a locking mechanism on each end face. The package can be opened if it is unlocked at both ends.

DE 19532162 a1 discloses a package made of cardboard, which consists of a front wall and a rear wall. A container is formed in the front wall, which container has a hole-like seam line in the edge region to the rear wall. The package can be opened along the perforation seam line.

Disclosure of Invention

The object of the present invention is to provide an environmentally friendly and economically producible packaging which can be opened in a defined manner in an advantageous manner.

This object is achieved according to the invention by a package according to claim 1. In further aspects, the invention relates to a bundle 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 is provided which has at least one perforation having a weakening which reduces the bending strength of the cellulose-containing material of the packaging in the region of the perforation or perforation line.

A perforation is understood to mean a material weakening in the sense of the packaging according to the invention, the bundle according to the invention and the method for packaging and/or opening the packaging according to the invention, wherein the perforation is a score line which partially cuts the cellulose-containing material from one side or is formed by cuts on both sides of the cellulose-containing material. The cuts are spaced apart from one another.

In a further embodiment, the perforation seam is a cutting line with gaps, wherein the gaps are distributed uniformly and/or non-uniformly.

The perforation is alternatively designed as a groove, which loosens the cellulose-containing material, in particular the fiber structure, and thus produces a material weakening in the region of the perforation line. In the sense of the packaging according to the invention, the mechanical folding or flanging of the cellulose-containing material in the region of the folding edge is an eyelet-like seam.

All the described perforation seam forms can be constructed individually or in combination on the packaging according to the invention and produce a material weakening in the region of the perforation seam lines.

The packaging is used in particular for packaging individual articles, in other words individual objects. The object to be packaged may be, for example, a toothbrush. The packaging according to the invention is however in principle suitable for packaging different kinds of objects. The packaging can in particular also be designed for packaging loose material. The package is preferably constructed in the form of a transparent plastic package (blister pack). This enables the packed item to be viewed without opening the package.

The package has a shell and a lid folded from a cellulose-containing flat material. The cellulose-containing flat material can be easily processed and recycled. In particular, the folding can be efficiently automated. The housing typically forms a hollow body which is open on one side. The shell and the lid enclose an interior space of the package. For this purpose, the cover is arranged on the housing or mounted on the housing. The cover may be flat. The cover may in particular extend in one plane. The item to be packed may be arranged in the inner space. The cellulose-containing flat material can be coated or waterproofed on one or both sides, in particular not water-absorbing. The coating or water barrier is preferably biodegradable.

The housing has a first sidewall. The first sidewall defines a boundary of an interior space of the package. The first sealing edge is bent outward away from the interior space along the first folding edge at the first side wall. In other words, the first sealing edge extends outwardly from the first sidewall. The first sealed edge constitutes an edge band of a desired width. The first sealing edge and the first side wall typically each extend in one plane. The first sealing edge and the first side wall may enclose an angle (outside with respect to the interior space) 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 may enclose a right angle.

The lid is bonded to the first sealed edge. The bonding can be carried out in particular by heat sealing with a bubble coating. The cover can have a section (region) for bonding with the first sealing edge, which section covers the first sealing edge. The lid and the first sealing edge may have outer contours that terminate substantially flush with each other. Preferably, the lid projects slightly beyond the first sealing edge, in particular by a maximum of 2mm, preferably by a maximum of 1 mm.

Since the first sealing edge and the lid extend away from the inner space, they can be gripped in an easy and comfortable manner by means of fingers, in particular the thumb and the index finger of the hand. The free length of the first sealing edge and the lid may be at least 1cm, preferably at least 1.5 cm.

According to the invention, it is provided that a perforation is formed on the first fold edge for tearing off the first sealing edge together with the section of the cover that is bonded to the first sealing edge from the first side wall. The perforated seam extends at least in sections along the first fold edge. The perforation simplifies the opening of the package. The perforation seam can be used to set a constant low force required for opening, in particular on a plurality of produced packages. To open the package, the outwardly projecting first sealing edge and the region of the lid fixed to the first sealing edge can be gripped and torn off jointly from the first side wall. For this purpose, the first sealing edge and the bonded section of the cover are moved away from the first side wall, so that the flat material of the housing is separated along the perforation. The shell has a second side wall at which the second sealing edge is bent outward away from the interior space along the second folded edge. The second side wall also defines a boundary of the interior space of the package. The lid is bonded to the second sealed edge. As in the case of the first sealing edge, an edge strip having a width is formed by the second sealing edge, which edge strip is permanently bonded to the cover. The package can thereby be closed in a particularly sealed manner. To open the package, the lid may be pulled away from the second sealed edge after tearing the first sealed edge away from the first sidewall. The tearing off of the first sealing edge together with the bonded section of the lid and the detachment of the lid from the second sealing edge can be carried out particularly comfortably in a single movement and without a surrounding grip.

In a particularly preferred embodiment, the perforation is configured with a perforation opening which passes completely through the flat material of the shell. This makes it possible to open the packaging with particularly low effort. The perforated seam can furthermore be produced particularly easily.

Alternatively or additionally, it may be provided that the perforation seam is formed with a recess in the flat material of the shell, wherein the remaining thickness of the flat material relative to the fold edges is further reduced at the recess. The recess does not pass completely through the flat material of the shell. In other words, the flat material is continuously constructed along the perforation. The inner space of the packaging or the packaged goods can be protected particularly effectively in the described manner against contamination, for example due to dust and/or liquid. In the region of the recess, in particular on the side next to the recess, the fibers, in particular cellulose, of the flat material can be separated. Alternatively or additionally, the flat material may be compressed below the recess (viewed in the thickness direction).

Preferably, the perforation seam at the first folding edge extends over the entire length of the first folding edge. This further simplifies tearing off of the first sealing edge from the first side wall. In particular, when opening the pack, care must not be taken as to which end of the folding edge the perforation is formed. The opening of the pack can be continued comfortably starting from the two ends of the fold edge and with substantially the same continuous tear resistance of the perforated fold edge.

The base element and the cover may be formed from a cellulose-containing flat material. This is considered advantageous in terms of environmental protection. The cover can be composed overall of a base element composed of a cellulose-containing flat material. Alternatively, an additional element of the cover, in particular a closure element for the viewing window, can be arranged on the base element. The additional element can also consist of a flat material containing cellulose. The cellulose-containing flat material of the shell, of the base element and of the additional element can each be of the same type. Alternatively, different types of cellulose-containing flat material can be provided for the shell, the base element and/or the additional element.

The first and second sidewalls typically abut one another. Preferably, the first and second side walls are connected to each other by an adhesive strip. This may improve the stability of the shell or package. The second sealing edge and the second sidewall extension are typically each in one plane. The second sealing edge and the second side wall may enclose an angle (outside with respect to the interior space) of at least 60 °, in particular at least 75 °, and/or at most 145 °, in particular at most 120 °. In a preferred further development, the second sealing edge and the second side wall can enclose a right angle. Typically, the housing has two second side walls and one second sealing edge each bent outwardly.

The shell may have a third side wall, which is preferably adjoined to this second side wall or these second side walls, and a third sealing edge, at which the lid is adhesively bonded, is bent away from the interior space along a third folding edge. The third sealing edge also forms an edge strip having a strip width, which is suitable for supporting the cover and for adhering the cover to the housing. The third sealing edge and the third side wall extension are typically each in one plane. The third sealing edge and the third side wall may enclose an angle (outside with respect to the inner space) of at least 60 °, in particular at least 75 °, and/or at most 145 °, in particular at most 120 °. In a preferred further development, the third sealing edge and the third side wall can enclose a right angle. The third side wall also defines a boundary of the interior space of the package. In particular, the interior of the package can be bounded circumferentially by the first side wall, the two second side walls and the third side wall.

Typically, the housing has a bottom which delimits the interior space on the side facing away from the cover. The side walls may be bent from the bottom along fold lines, respectively. The bottom and the first, second and/or third side wall typically each extend in one plane. The bottom encloses an angle of at least 60 °, in particular at least 75 °, and/or at most 145 °, in particular at most 120 °, with the first, second and/or third side wall or may enclose an angle (inboard with respect to the interior space) of at least 60 °, in particular at least 75 °. In a preferred further development, the bottom and the first, second and/or third side wall can enclose a right angle.

Preferably, the strength, in particular the peel strength, of the bonding of the lid to the second sealing edge is greater than the strength of the material of the lid and/or the shell. It is thereby possible to retain the adhesive connection between the lid and the second sealing edge when the lid is pulled away from the second sealing edge and to effect a tear in the material of the lid or of the housing instead. This proves to be advantageous in terms of the opening behaviour of the package, in particular the force required for opening.

Alternatively or additionally, it may be provided that an eyelet is formed on the second fold edge for tearing off the second sealing edge together with the section of the lid bonded to the second sealing edge from the second side wall. The perforation seam at the second folding edge can be designed such that the opening of the packaging can be carried out with particularly low effort. The perforation on the second folded edge can be formed with a continuous perforation opening or recess, as in the perforation on the first folded edge. The perforation seam at the second fold edge extends at least in sections along the second fold edge. Typically, the perforation seam at the second folded edge is formed in the region of the second side wall adjoining the first side wall.

The cover and/or the housing may have at least one viewing window. The viewing window allows the interior space of the package to be viewed without opening the package. The viewing window may be constituted by a recess in the material of the shell or the cover. This simplifies the manufacture of the package. Preferably, the viewing window is closed by a transparent closure element. Thereby, the articles received in the inner space of the package may be effectively protected against contamination, in particular due to dust and/or liquid. The closure element may be formed from a cellulose-containing flat material, such as a bio-based film.

It is advantageously provided that the suspension recess extends through the first sealing edge and the section of the cover which is bonded to the first sealing edge. The packaging can be suspended in an advantageous manner by means of the suspension recess, in particular for displaying the packaged articles or the packaging. Furthermore, the hanging recess may facilitate fixedly holding the first sealing edge and the section of the lid to which the first sealing edge is bonded when torn off the first side wall. The bonding of the lid to the first sealing edge typically extends around the suspension recess, preferably continuously around the suspension recess. This may improve the stability of the package in the region of the suspension recess and in particular help to avoid tearing or tearing off the suspension recess.

A mount for securing an object that can be received in the package can be arranged in the housing. The insert may help to avoid damage to the object and/or packaging. Preferably, the insert is made of a flat material containing cellulose.

Bundling according to the invention

Within the framework of the invention, a bundle is also provided, which has the aforementioned packaging according to the invention and an object, which is received in the packaging. The advantages of the packaging according to the invention can be utilized by bundling for packaged objects, in particular for the display behavior of said objects for sale. The object is typically constructed as a single piece of the article. The object may be a toothbrush, for example. However, in principle, the object is not restricted to any particular object, as long as the object is suitable for packaging with a flat material containing cellulose, in particular with regard to its dimensions and properties. The dimensions of the object, in particular the maximum extension, are typically in the range of centimeters to decimeters; in special cases also in the millimeter range. The bundle may contain one unique object. Alternatively, it can be provided that the bundle comprises a plurality (typically up to 10 or 20, and in special cases also more) of individual objects in a single aforementioned packaging according to the invention.

The bundle may contain a plurality of objects in the form of loose material, which are received in the package. If the perforation on the first folded edge and/or the second folded edge is formed with a continuous perforation opening, the smallest particle size of the bulk material is preferably much larger than the largest dimension of the perforation opening, in particular at least 5 times the largest dimension of the perforation opening. The particle size of the bulk material can be in particular in the millimeter range.

Opening method according to the invention

Within the framework of the invention, a method for opening a package is also specified. The package has a shell and a lid folded from a cellulose-containing flat material. The shell and the lid enclose an interior space of the package. The shell has a first side wall at which a first sealing edge is bent outward away from the interior along a first folding edge. The shell also has a second side wall where the second sealing edge is bent outward away from the interior space along the second folded edge. The lid is bonded to the first sealed edge and the second sealed edge. An eyelet is formed on the first fold edge. The package may have the aforementioned additional features of the package according to the present invention.

The method comprises the following steps

a) Tearing the first sealing edge together with the section of the cover bonded to the first sealing edge from the first side wall along the perforation-like seam at the first folding edge,

b) the lid is pulled away from the second sealed edge.

Step a) is used to prepare for step b). The perforation of the first folding edge makes it possible to easily carry out the tearing off in step a), in particular with little effort. Furthermore, a defined breaking process can be predefined by means of the perforation seam. Das tears off the first sealing edge and the section of the lid bonded to the first sealing edge from the first side wall in step a) in principle without the first sealing edge being detached from the lid. In other words, the first sealing edge and the lid remain bonded to each other when the first sealing edge and the section of the lid bonded to the first sealing edge are torn off the first side wall. To carry out step a), typically the first sealing edge and the region of the lid which is bonded to the first sealing edge are gripped by the fingers, in particular the index finger and the thumb, of one hand and pulled away from the first side wall. The packaging can be gripped here by a second hand in the region of the shell or around the interior space.

The packaging is continued, in particular completely opened, by step b). Opening the inner space while performing step b). The detachment of the lid from the second sealing edge can be carried out particularly comfortably by the preparatory step a). The partially opened configuration of the package is automatically obtained by tearing off the first sealing edge together with the bonded section of the lid from the first side wall, and the continued separation of the lid from the second sealing edge can be carried out particularly easily from this configuration, in particular by peeling. Steps a) and b) can advantageously be carried out in a single uniform movement. Step b) may begin before step a) is completely finished. In other words, the lid may already be partially detached from the second sealing rim before the first sealing rim and the section of the lid bonded to the first sealing rim are also completely torn off the first side wall.

Preferably, the shell and/or the cover comprise fibers, in particular cellulose, which are broken in step b). In other words, the fibers are broken or separated in step b). The breaking of the fibres shows to be advantageous in terms of the opening behaviour of the package. In order to ensure that the fibers are broken in step b), the strength, in particular the peel strength, of the bonding of the lid to the second sealing edge may be greater than the strength of the material of the lid and/or the shell.

Providing method according to the invention

Finally, the invention relates within the framework of a method for providing an object. The method comprises the following steps:

A) providing a trim and a cover consisting of a flat material containing cellulose,

B) creating a first folded edge having a hole-shaped seam in the trim material, wherein the first folded edge demarcates the first side wall from the first sealing edge, and creating a second folded edge in the trim material, wherein the second folded edge demarcates the second side wall from the second sealing edge,

C) the cut material is folded into a shell,

D) an object is placed in the shell and,

E) the cover is bonded to the first and second sealed edges of the housing,

F) the packaging is opened by tearing off the first sealing edge together with the section of the lid bonded thereto from the first side wall along the perforation seam at the first folding edge in step a), and by pulling the lid away from the second sealing edge in step b).

The object is typically removed from the shell of the opened package in step G).

The aforementioned packages according to the invention having a first side wall and a second side wall, which have a first sealing edge or a second sealing edge, respectively, can be manufactured by steps a), B), C) and E). The packages obtained by steps a), B), C) and E) may have the further features of the packages according to the invention described previously. In particular, it can be provided that the perforation openings are produced completely through the trim material in step b). Alternatively, it can be provided that a recess in the flat material of the trim material is produced along the fold edge in step b). The first folded edge and the second folded edge may be applied to the trim material. The folding of the shells in step C) may be performed manually, partially automatically or preferably fully automatically (by a machine). Typically, the first side wall and the second side wall are connected to one another, for example adhesively bonded to one another by means of an adhesive strip, following the folding. Between steps C) and D) inserts can be inserted for fixing the object in the housing.

By step D), the object is arranged in the inner space of the closed package. The aforementioned bundling according to the invention can furthermore be obtained by step D). The bundle may have additional features as previously described. The object is surrounded by a packaging after carrying out step E). The packaging can protect the object, in particular against contamination and/or damage. The adhesion of the lid to the first and second sealing edges in step E) can be carried out by heat sealing, in particular in the case of the use of a bubble coating. The adhesion of the lid to the first sealing edge and the second sealing edge in step E) can be carried out manually, partially automatically or preferably fully automatically (by machine).

Opening the package in step F). After opening the package, the object can be removed from the package in step G). The opening of the package is carried out in step F) by means of the method according to the invention described previously. The advantages of the opening method according to the invention can thus be exploited for providing objects, in particular in connection with removing packaging from objects. In step b) the fibers, in particular the cellulose, of the shell and/or the lid are preferably broken when the lid is pulled away from the second sealed edge.

Further features and advantages of the invention emerge from the description and the drawings. The features mentioned above and still further embodiments can be used according to the invention individually or in any combination of several. The embodiments shown and described are not to be understood as a final enumeration but rather have exemplary character for the description of the invention.

Detailed Description

Fig. 1 shows a package 10. The package is in the configuration shown in figure 1 in a partially open state. The object 12 is received in the package 10. The package 10 together with the objects 12 form a bundle 14. The object 12 is shown here symbolically almost as a cylinder.

The package 10 has a shell 16 and a lid 18. The shell 16 is folded from a flat material containing cellulose, such as paper or cardboard. The cover 18 has a base element 20, which here is likewise made of a flat material containing cellulose, for example paper or cardboard. Two observation windows 22 are formed in the base element 20. The viewing window 22 can be closed by a transparent closure element, not shown in detail. The closure element may be formed from a transparent flat material, such as a bio-based film.

The shell 16 and the lid 18 (in the closed state of the package 10) together enclose an interior space 24 of the package 10. The object 12 is disposed in the interior space 24. An insert 26 for fixing the object 12 can furthermore be arranged in the interior 24.

Fig. 2 shows the package 10 in a perspective view from the perspective of the shell 16. The package 10 is shown in a closed state in fig. 2.

The housing 16 is substantially square in shape here. The shell 16 has a bottom 28. The first side wall 30, the two second side walls 32, and the third side wall 34 (hidden in FIG. 2) are configured to abut the bottom 28. The

side walls

30, 32, 34 are each divided by a fold line 35 from the bottom 28 or are each bent at 90 ° at the fold line 35 relative to the bottom 28.

The shell 16 has a first sealing edge 36. The first sealing edge 36 is bent along a first folding edge 38 relative to the first side wall 30. The first sealing edge 36 extends outwardly from the interior space 24 away from the first sidewall 30.

The shell 16 has two second sealing edges 40, one of which is obscured in fig. 2. The two second sealing edges 40 are each bent along the second folding edge 42 relative to the respectively associated second side wall 32. Two second sealing edges 40 each extend outwardly from the interior space 24 away from the second sidewall 32.

The shell 16 may have a third sealing edge (covered in fig. 2). The third sealing edge is bent along the third folding edge (which is also hidden) relative to the third side wall 34. The third sealing edge extends outwardly from the interior space 24 away from the third sidewall 34.

The lid 18 is bonded to the first sealed edge 36, the two second sealed edges 40, and the third sealed edge. The bonding can be carried out as a heat seal. The adhesive is typically applied in a planar manner, in particular over the entire surface of the sealing

edge

36, 40 facing the cover 18. The peel strength of the bond may exceed the corresponding strength of the materials of the shell 16 and cover 18.

An eyelet 44 is formed on the first fold edge 38. The perforation 44 extends over the entire length of the first fold edge 38. In other words, the shell 16 is folded from a cellulose-containing flat material which is perforated along the first folding edge 38. The first fold edge 38 and the perforation 44 can be machined into the flat material in a common working process.

The perforation 44 can be configured with a perforation opening 46 therethrough, see fig. 5. The perforation openings 46 pass completely through the flat material of the shell 16. Leaving tabs 48 between the perforation openings 46. The height H1 of the web 48 can be reduced relative to the thickness D1 of the flat material of the housing 16 by embossing the first fold edge 38.

Alternatively, the perforation 44 may be configured with a recess 50, see fig. 6. Between the recesses 50, projections 52 are formed. The remaining thickness D2 of the flat material in the region of the recesses 50 is reduced relative to the thickness D3 of the flat material in the region of the projections 52. The thickness D3 may correspond to the maximum thickness of the first fold edge 38. The thickness D3 is in principle smaller than the thickness D1 of the flat material of the shell 16 beyond the fold edge 38.

A further perforated seam (not shown in detail) can also be formed at least in sections along the second fold edge 42. The further hole-like seam can be formed in particular at the first folding edge 38 adjacent to the end of the second folding edge 42. The further perforation may be configured with a perforation opening 46 or a recess 50 therethrough; reference is made in this respect to the preceding description.

The package 10 may have a hanging recess 54. A hanging recess 54 extends through the first sealing edge 36 and the lid 18 in the area where the first sealing edge is bonded to the lid. The suspension recesses 54 are therefore bordered two-layer here.

In a first step 102 (see fig. 7), the first sealing edge 36 and the section of the lid 18 bonded thereto are torn off together from the first side wall 30 in order to open the package 10. The first sealing edge 36 and the section of the cover 18 that is bonded thereto can be moved in the direction of the arrow 56 (see fig. 3) and away from the housing 16. Typically, the first sealing edge 36 and the cover 18 are clampingly held between the fingers of the hand (not shown) for this purpose.

The partially torn-off state of the package 10 is shown in fig. 3. The area of the first folding edge 38 on the right in fig. 3 is broken along the perforation 44, while the left part of the first folding edge 38 in fig. 3 is still intact. In other words, a continuous material connection between the first sealing edge 38 and the first side wall 30 by means of the flat material of the housing 16 is also present in the left-hand portion of the first folding edge 38.

To continue opening the package 10, the lid 18 is pulled away from the two second sealed edges 40 at step 104 (see fig. 7), see fig. 4. The movement of the first sealing edge 36 in the direction of the arrow 56 according to fig. 3 can be substantially maintained for this purpose or deflected in its direction, to be precise, away from the housing 16.

The cellulose (not shown in detail) of the lid 18 and/or the shell 16 may be broken when the lid 18 is pulled away from the second sealed edge 40. Said breaking of the cellulose can be promoted by the cover 18 being bonded to the shell 16 with a (peel) strength which is greater than the corresponding strength of the shell 16 or of the material of the cover 18. The portion of the broken cellulose of the second sealing edge 40 may be retained on the lid 18 in the region 58 of the initial bonding of the second sealing edge 40 to the lid 18 by breaking the cellulose. Accordingly, portions of the cellulose of the lid 18 may also be retained on the second sealed edge 40.

Fig. 8 shows a flow chart of a method 200 for providing an object 12, see fig. 1. The providing method 200 is set forth below with respect to the foregoing examples of the package 10 or bundle 14.

First, in step 202 or 204, a trim material made of a flat material containing cellulose and the cover 18 are provided. The shell 16 is obtained from the trim material during the continuation of the method 200. For this purpose, in step 206 or 208, the first folded edge 38 and the second folded edge 42 with the perforation 44 are machined into the trim material. The first folded edge 38 delimits the first side wall 30 of the shell 16 under manufacture from the first sealing edge 36. The second folding edge 42 accordingly delimits the second side wall 32 of the shell 16 under production from the second sealing edge 40. Typically, in step 208, a further second folded edge 42 is also introduced into the trim material, which delimits the further second side wall 32 of the producing shell 16 from the further second sealing edge 40. Accordingly, a third folded edge may also be machined into the trim material in step 208, which demarcates a third side wall of the shell 16 under production from a third sealing edge. The trim material may then be folded in step 210 so that shells 16 are obtained.

The insert 26 may be placed into the shell 16 in an optional step 212. Object 12 is placed into shell 16 in step 214. Alternatively, the insert 26 or an additional insert (not shown) may be placed in the shell 16 after the object 12 is placed in step 214.

After the placement of the object 12 and, if appropriate, all inserts 26, the cover 18 is bonded in step 216 to the first sealing edge 36, to this second sealing edge 40 or to these second sealing edges 40 and, if appropriate, to the third sealing edge. Thereby a closed package 10 or bundle 14 of packages 10 with closed arranged objects 12 is obtained.

The package 10 is then opened by means of the method 100 described above (see fig. 7). Object 12 may then be removed from opened package 10 or shell 16 of the package in step 218. The object 12 may now be supplied for further applications.

In summary, the invention relates to a packaging 10, in particular for individual articles, having a shell 16 and a lid 18 which are folded from a flat material containing cellulose, wherein the shell 16 and the lid 18 enclose an interior space 24 of the packaging 10, wherein the shell 16 has a first side wall 30 at which a first sealing edge 36 is bent away from the interior space 24 along a first folding edge 38, wherein the lid 18 is adhesively bonded to the first sealing edge 36, characterized in that a hole-like seam 44 is formed on the first folding edge 38 for tearing off the first sealing edge 36 together with the section of the lid 18 which is adhesively bonded thereto from the first side wall 30. The invention also relates to a bundle 14 having the package 10 and an object 12 received in the package 10. The invention further relates to a method 100 for opening a package 10, which also has a second side wall 32, at which a second sealing edge 40 is bent away from the interior 24 along a second folding edge 42, wherein the lid 18 is bonded to the first sealing edge 36 and the second sealing edge 40, with the following steps:

a) the first sealing edge 36 and the section of the cover 18 to which it is bonded are torn 102 together along the perforation 44 in the first folding edge 38 from the first side wall 30,

b) the lid 18 is pulled 104 away from the second sealing edge 40.
