EP1873080B1 - Packaging for an element with a circulating lug - Google Patents

Abstract

The package (3) has a projection enclosed around an element e.g. plaster roller, and a surface element (1) with an opening. Another surface element is formed as one-piece and has a holding section partly extending over the opening, where the holding section has a tearing edge (11). The surface element has connecting sections (18, 19) that connect attachment sections (8, 9) of the element (1) and the holding section with each other. The sections (18, 19) run bendingly to the plane and the holding section, and the edge runs parallel to the plane and the element (1).

Description

The present invention relates to a packaging for an element with a circumferential projection around the element, comprising a first surface element which extends at least partially parallel to the plane and a second surface element, wherein the first surface element has a recess, wherein the second surface element a fixing portion abutting and connected to the first surface member, and wherein the second surface member has a holding portion extending at least partially across the recess, the holding portion having a tear edge; which faces the first surface element, the second surface element having a connecting portion, wherein the connecting portion connects the fixing portion and the holding portion, and wherein the connecting portion is inclined to the plane.

In particular, in the packaging of band-shaped material such as plaster, which is wound on rollers, which in turn are surrounded by a shell, there is the problem that the role with the shell alone has too small dimensions to ensure adequate theft protection. In addition, there is not enough surface area on the roll and wrapper that could be printed.

Therefore, it is provided in the prior art that the roll is received by a so-called blister packaging, which is a generally transparent, deep-drawn plastic part which forms a cavity for receiving the roll, and a cardboard surface element, which over the Opening of the plastic part is glued comprises. The cardboard sheet element encloses the roll in the cavity, and the carton panel enlarges the dimensions and provides enough space to print information about the tape material.

A disadvantage of such blister packaging, however, is that they comprise a plastic part, its disposal in comparison to the cardboard surface element is associated with increased costs. In addition, the plastic part and the cardboard element must be separated from each other during disposal.

Furthermore, it is from the DE 94 01 867 U1 It is known to attach an element with a circular cross-section to a flat package without the use of a plastic part. In this case, the element has a circumferential projection, and the packaging comprises a first and a second surface element. In the first surface element, a recess is provided, through which the element extends. Opposite the first surface element, a second surface element is provided, which is connected along an edge pivotally connected to the first surface element. The projection bears against the second surface element facing side of the first surface element and is clamped by the second surface element.

However, such a package is disadvantageous in that, due to the thickness of the projection perpendicular to the packaging plane, the second surface element can not rest flat against the recess on the first surface element, since otherwise too great stresses would occur in the second surface element which would lead to that the material of the second surface element ruptures. However, this in turn means that the element must have a comparatively far projecting projection in order to be securely fastened to the packaging.

But even if the second surface element abläge on the first surface element, there would be the problem that a user would have difficulties to open the package, since a provided on the second surface tear edge due to the stresses in the material also in the packaging level run and so close to the first surface element anläge. It would thus be difficult to engage behind the holding portion of the second surface element and this to break away from the first surface element, so that the element is released.

In the US 2,993,590 a packaging according to the preamble of claim 1 is described. A disadvantage of the packaging described therein, however, that a holding portion and a tear-open edge are provided which extends in the plane of the first surface element of the package. This makes it extremely difficult for a user to grasp the tearing edge and engage behind the holding section.

Therefore, the present invention based on the prior art has the object to provide a package for an element with a circumferential projection in a packaging level, in which the element, even with a projection which has only small dimensions in the packaging level, securely on the packaging held and the holding section can still be well engaged.

According to the invention, this object is achieved in that the holding section and the tear-off edge extend parallel offset from the plane and spaced from the first surface element.

By the connecting portion, an inclined transition is provided, so that the holding portion can extend parallel to the height of the projection offset from the plane of the first surface element and the fixing portion can simultaneously extend close to the recess and thus to the projection, without causing large voltages build up in the material of the second surface element. As a result, even with a projection, the element can be held firmly in the packaging, which has only a small dimension in the packaging plane.

Due to the parallel offset holding section, the tear-open edge can also be spaced apart from the first surface element run and therefore easily be engaged behind by a user to tear the holding section.

In a preferred embodiment, the second surface element is integrally formed. In this case, the second surface element can be cut in one operation from the raw material, so that the production of the packaging according to the invention is further simplified.

Furthermore, it is preferred if the holding section adjacent to the tear-open edge has a gripping tab which runs in the plane of the holding section. This allows the holding section to be easily grasped and torn off when the element, for example a plaster roll, is to be removed.

In a further preferred embodiment, a perforation is provided between the holding section and the connecting section, so that the holding section can be released from the connecting section at a defined location when the package is opened.

In addition, it is preferable that the attachment portion includes a first attachment portion and a second attachment portion, the connection portion includes a first connection portion and a second connection portion, the first connection portion adjoins the first attachment portion, and the second connection portion adjoins the second attachment portion and the retaining portion between the first Connection area and the second connection area is arranged. Since the holding portion is then surrounded by two sides of abutting on the first surface element mounting portions, the holding portion is firmly held on the first surface element and has little opportunity to deform. Thus, the element is also stably held on the package and this then does not tend to buckle.

More preferably, when the connecting lines between the holding portion and the first connecting portion and between the holding portion and the second connecting portion have an arcuate course and are arranged opposite to each other that the holding portion has a convex shape, in particular a circular recess in the second surface element be covered in a suitable manner by the holding section. However, because the connecting lines do not correspond exactly to the circular course, but rather have a merely curved shape, stress peaks in the second area element are avoided.

Particularly preferably, a first perforation line can be provided between the first connection region and the holding section, and a second perforation line can be provided between the second connection region and the holding section, so that the packaging can be opened in a defined manner.

In this case, the first perforation line and the second perforation line may comprise interrupters which have an oblique section which extends at an angle to the direction of progression of the perforation line. In this way, it is achieved that the perforation lines do not tear due to the tensions existing along the connecting lines, but only when a user grasps the tearing edge. It is thus reduced the risk that the holding section dissolves by itself from the connection areas. In this case, an improved stability is achieved, in particular, when the oblique sections extend away from the holding section.

Preferably, the breakers are arranged with the inclined portion in the region of the end of the perforation lines, which faces the tearing edge, since here at the beginning of the perforation lines occurring in the transverse direction to the direction of the perforation lines voltages are greatest and there is a risk that the beginning the perforation lines opens automatically.

More preferably, between two interrupters with an oblique section, there is provided a breaker extending completely along the direction of progression of the perforation line in order to further increase the strength of the perforation line.

In a further preferred embodiment, the second surface element is made of cardboard material, wherein the fiber direction of the cardboard material extends at an acute angle to the direction of the connecting lines between the holding portion and the connecting portions. This makes it possible that the cardboard material in the region of the connecting portion has a change in length perpendicular to the direction of fiber travel.

Thus, the first and second sheet members can be made of a strip having a certain width, and after the production of the package, the outer edges of the elements are aligned, although the second surface element, unlike the first surface element, has an area which is at an angle to the packaging plane , In addition, the tendency of the second surface element is reduced to buckle.

The Fig. 1 and 2 show the blanks 1 ', 2' of cardboard material for the first surface element 1 and for the second surface element 2, from which a package 3 for an element 4 is formed with a circumferential projection 5 in a plane (see Fig. 4 . 5 and 6 ). The element 4 may in particular be a roll for a band-shaped material such as plaster, which is surrounded by an annular sheath, which in turn has the projection 5.

In this case, the blank 1 'for the first surface element 1 on a circular recess 6 in this case, whose dimensions are adapted to the cross section of the element 4 in the region adjacent to the projection 5, so that the element 4 can be inserted through the recess 6 and the projection then rests against the first surface element 1, as also in the FIGS. 5 and 6 is shown. Furthermore, the first surface element has 1 a Euro hole 7, so that the package 3 can be hung in a known manner.

The integrally formed blank 2 ', from which the second surface element 2 is formed, initially comprises a first fastening region 8 and a second fastening region 9, which together form a fastening section. Furthermore, a holding section 10 is provided between the attachment regions 8, 9, which in turn has a tear-open edge 11, which lies opposite the first surface element 1 in the packaging 3 formed later (see FIG. Fig. 4 ). In this preferred embodiment, a grip tab 12 is provided on the holding portion 10, which is adjacent to the tear-open edge 11.

The blanks 1 ', 2' preferably have the same width, so that they can be cut from the same roll material, without causing too much waste.

The holding portion 10 is limited in this preferred embodiment in the direction of the attachment areas 8, 9 of a first perforation line 13 and a second perforation line 14, so that the holding portion 10 can be separated in a simple manner defined by the remaining part of the second surface element 2. The perforation lines 13, 14 extend arcuately, so that the holding portion 10 has a convex shape.

As in the enlarged view in Fig. 3 1, the perforation lines 13, 14 have, on the one hand, first interrupters 15, that is, sections in which the material of the second surface element 2 is severed, which extend completely along the direction of progression of the perforation line 13. On the other hand, second interrupters 16 are also provided, which have an oblique section 17, wherein the oblique section 17 extends at an angle to the running direction of the perforation line 13 and away from the holding portion 10. In this way, the perforation lines 13, 14 in the area where the second breaker 16 are provided with the inclined portions 17, a greater load capacity against stresses in a direction perpendicular to the direction of the perforation lines 13, 14. To further increase this capacity, is in this respect preferred embodiment between two second breakers 16 with an oblique portion 17 each one completely along the direction of the perforation 13 extending first breaker 15 is provided.

Overall, the second breaker 16 are arranged with the inclined portion 17 in the region of the end of the perforation line 13, which is adjacent to the pull tab 12 and thus also the tearing edge 11 faces. This has the advantage that it reinforces the perforation lines 13, 14, especially in the initial area, which is exposed to the strongest transverse loads.

In the Fig. 4 . 5 and 6 3 shows a packaging 3 with an inserted element 4, which is formed from the blanks 1 ', 2', wherein the holding section 10 extends over the recess 6 and wherein in the manufacture of the packaging 3 a connecting section is formed, which has a first connecting region 18 and a second connecting portion 19 includes (s. Fig. 4 ). The first connection region 18 extends between the holding section 10 and the first attachment region 8 and the second connection region 19 between the holding section 10 and the second attachment region 9, so that the connection regions 18, 19 adjoin the attachment regions 8, 9. As in particular from Fig. 6 As can be seen, the connecting portions 18, 19 are inclined to the packaging plane, which is defined by the first surface element 1 and connect As a result of the inclination of the connecting regions 18, 19, the holding section 10 runs parallel between the tear-open edge 11 and a crease line 20 offset from the first surface element 1 and parallel to the packaging level. Thus, the tearing edge 11 with the grip tab 12 is spaced from the first surface element 1 (s. Fig. 5 ) and can be easily grasped by a user to subsequently separate the holding section 10 along the perforation lines 13, 14 from the connection areas 18, 19. In this case, the tear-open edge 11 does not have to be lifted, in particular, by the first surface element 1.

Because the holding section 10 extends parallel to the first surface element 1 and is not attached directly but via the inclined connection regions 18, 19 and the attachment regions 8, 9 to the first surface element 1, the holding section 10 is not under tension in such a way that the tearing edge 11 tends to be applied to the first surface element 1. Rather, in this invention Verpakkung 3 ensures that the tearing edge 11 is spaced from the first surface element 1.

In addition, the inclined course of the connection regions 18, 19 allows the attachment regions 8, 9, along which the second surface element 2 is connected to the first surface element 1 to extend as close as possible to the element 4 with the projection 5, and the element 4 is very strong can be trapped. On the other hand, this makes it possible to form the projection 5 on the element 4 so small that the element 4 can be removed from the packaging 3 without tearing off the holding section 10.

As it turned out 3 and 4 results, the second breaker 16 are connected to the inclined portion 17 with the advantage that the predetermined breaking lines in the region of the perforation line 13, 14, where second breakers 16 are present between the free end of the inclined portion 17 and the end of the next breaker 15 or 16 run and thus almost perpendicular to the actual course of the perforation line 13, 14. This leads to the fact that occurring perpendicular to the perforation lines 13, 14 tensions difficult to tearing the perforation 13, 14. It is thus reduced the risk that the holding portion 10 automatically releases from the connecting portions 18, 19.

In this preferred embodiment, a change in length of the material of the second surface element 2 in the region of the connecting regions 18, 19 is brought about during the production of the packaging 3 from the blanks 1 ', 2'. This change in length runs essentially perpendicular to the course of the connecting regions 18, 19. This initially results in the side edges 21 of the surface elements 1, 2 being aligned despite the deformation when the surface elements 1, 2 are connected to one another. In addition, the change in length prevents tensions in the second surface element 2 from being caused by the second surface element 2 having a different width after the formation of the connection regions 18, 19 as a result of their inclination below the crease line 20 above it (s.
Fig. 4 ). Otherwise, these stresses would cause the second surface element 2 to buckle.

In order to facilitate the bringing about of a change in length in the region of the connecting regions 18, 19, the fiber running direction of the cardboard material in the preferred exemplary embodiment runs in the direction of the arrow 22 (see FIG. Fig. 2 ) and thus at least at an acute angle to the course of the connecting line or perforation line 13, 14 between the holding portion 10 and the connecting portions 18, 19 or in parallel thereto.

At this point, it should be noted that in the embodiment described here, the packaging 3 is formed from two separate blanks 1 ', 2'. However, it is also conceivable that the packaging is produced from a single blank, in which the first surface element and the second surface element are connected to one another along an edge.

In the case of the packaging 3 according to the invention, an inclined transition is created by the connecting section formed from the connecting regions 18, 19, so that the holding section 10 extends parallel to the first surface element 1 offset by the height of the projection 5 and the fastening section extends from the fastening regions 8, 9 at the same time can extend close to the recess 6 and thus to the projection 5, without building up large stresses in the material of the second surface element 2. As a result, the element 4 can be held firmly even in the case of a projection 5 in the packaging 3, which only has a small dimension in the plane of the packaging 3. The tearing edge 11 is likewise spaced apart from the first surface element 1 by the holding section 10, which extends offset in parallel, and can therefore easily be grasped behind by a user in order to pull the holding section 10 free.
