Description

Background of the Invention

The invention relates to a blank for unfolding a holding device for containers with a beaded edge on the upper side, the blank having a cover section for arranging on a row of containers, and two opposing fixing sections being formed on the side of the cover section, which are connected to the cover section by fold lines Such blanks and the holding devices obtained from them are made, for example DE 602 12 630 T2 and WO 2018/035344 A1 known. In the case of these previously known blanks, curved edges are provided on the fixing sections for gripping under the beaded edges of cans. The curvature of the edges is already created in the flat cut and follows a rounding of the cans; in other words, the edges for holding each can already run curved around a respective central axis in the flat state of the blank.

Out of U.S. 2011/0000799 A1 a blank for a holding device for cans is known, which has star-shaped recesses for receiving the cans with edge sections curved towards the respective can. The inwardly projecting crests of the edge sections can reach under the rims of the cans when the cans protrude through the recesses. In WO 2009/023822 A1 discloses a similar blank in which the recesses have U-shaped sections.

For the transport and handling of bundles with containers, such as cans, it is important that the containers are held securely and stably. At the same time, the container and its holding device should be simple and inexpensive to produce. Furthermore, it is desirable that the containers can be easily removed from the holding device.

object of the invention

It is an object of the invention to improve the combining of containers to form a bundle.

Description of the invention

This object is achieved according to the invention by a blank having the features specified in claim 1, a holding device according to claim 13 and a container according to claim 14. The respective dependent claims and the description specify advantageous embodiments.

According to the invention, a blank is provided for unfolding a holding device for containers with a beaded edge. The holding device can be obtained by folding the blank. The containers typically have a cylindrical lateral surface. Typically, on the upper side, a beaded rim protrudes radially outward beyond the lateral surface of the container. The lateral surface can taper conically towards the beaded edge. The containers can be cans, for example beverage cans.

The blank basically consists of a flat material. The flat material is preferably a cellulose-containing flat material, in particular cardboard. Cellulosic flat material can be easily recycled. The flat material can be coated and/or printed. The coating or printing is preferably water-repellent. Alternatively or additionally, water-repellent additives can be introduced into the cellulose-containing flat material. The flat material can be a composite material, for example a laminate. In particular, the flat material can be laminated with a plastic film. The blank is preferably in one piece.

The blank has a cover section. The deck section can be placed on a number of containers. In other words, the cover section can cover the containers arranged in a row on the upper side. The row of containers typically runs in a straight line. The row includes at least two containers. Typically, the row comprises at most six, in particular at most five, containers. For example, the array may include three containers.

Two fixing sections are formed on the cover section. The fixing sections are arranged opposite to each other on the cover section. In other words, the fixing sections are on opposite sides of the cover section. The fixing sections run along the row of containers when they are held on the holding device obtained from the blank. The fixing sections are each connected to the cover section via a fold line. The fold lines can each comprise a plurality of sections which are separate from one another. Each fold line typically extends in a straight line overall in order to enable the respective fixing section to be angled relative to the cover section. The fold lines can be formed with embossing, perforations and/or scoring.

According to the invention, holding edges for gripping under the beaded edges of the containers on the fixing sections are formed by rectilinear main cutting lines which run offset parallel to the fold lines. The main cutting lines run between tween the cover section and the respective fixing section. The main cutting lines separate the cover section and the fixing sections from one another in certain areas. The major cut lines are typically offset outwardly, relative to the row of containers, from the fold lines. When a holding device obtained from the blank is placed on the container, the holding edges reach under the beaded edges of the containers, while the cover section rests on the top of the containers, typically directly on the beaded edges. Since the cover sections and the holding edges rest on the containers or their beaded edges on different sides (namely above and below with respect to a normal use or storage position of the containers), the containers are held immovably on the holding device in the direction of their longitudinal axes. Typically, two holding edges oppose each other with respect to the longitudinal axis of the container held by them. Due to the straight course of the main cutting lines in the blank, a defined contact of the holding edges with the beaded edges occurs. In particular, the holding edges lie diametrically opposite one another in a locally limited contact zone on the beaded edge of the respective container. Due to the approximately punctiform contact of the holding edges on the beaded edges in the respective contact zone, a comparatively strong latching of the containers on the holding device can be achieved. The containers are therefore held particularly securely. At the same time, the rectilinear course of the main cutting lines ensures a high level of stability of the fixing sections in the area of the holding edges, particularly with regard to loading by the weight of the containers. The risk of the fixing sections buckling is effectively reduced by the straight course of the main cutting lines in the blank. Furthermore, the locally limited contact zones form a rotary joint about which the containers can be rotated for removal from the holding device.

Preferably the blank has two cover sections for placement on each row of containers. Each row may comprise, for example, three containers as described above. The deck sections or the rows of the containers generally run parallel to one another. On the cover sections there are mutually opposite fixing sections which are each connected to the respective cover section via a fold line. Holding edges for gripping under the beaded edges of the containers on the fixing sections are formed by rectilinear main cutting lines, which run offset parallel to the fold lines. In other words, the blank can have two similar holding devices, each for a row of containers. Each of the holding devices has a cover section and two fixing sections with holding edges formed by rectilinear main cutting lines.

Preferably, the middle, i. H. the fixing sections running between the rows or the cover sections are connected to one another via a longitudinal fold line. The longitudinal fold line can be formed with embossing, perforations and/or incisions. The longitudinal fold line makes it possible to bend the fixing sections that adjoin one another against one another. This allows the containers of the two rows to be brought into abutment when the respective holding edges are snapped under the beaded edges.

Advantageously, a contact section for contacting a lateral surface of the container adjoins the two outer fixing sections. If the blank has several cover sections, the outer fixing sections do not run between the rows or the cover sections. When a holding device obtained from the blank is placed on the rows of containers, the contact sections prevent the containers from moving away from one another transversely to the rows. If the blank has only a single cover section, the two fixing sections are (inevitably) outer fixing sections with respect to the cover section or the one row. The fixing sections then stabilize the containers transversely to the direction in which the row extends.

The contact sections particularly preferably have tabs for connecting the contact sections to one another. The tabs make it possible to fasten one plant section to the other plant section. For this purpose, the tabs of the two contact sections can be glued together or hooked together. The connection of the contact sections created by the tabs further stabilizes the holding device. The tabs can rest against the lateral surfaces of the containers. This means that the containers can also be fixed in place. In particular, the tabs can prevent the containers from moving apart along the rows.

A bending line can run in each case between the contact sections and the fixing sections. The bending line can be formed with embossing, perforations and/or carvings. The bending line is preferably formed in sections with, in particular curved, punching lines. The punching lines are typically arranged at the level of the holding edges, ie the punching lines and the respective holding edges are arranged at positions corresponding to one another along the rows. The bending lines and in particular the punching lines make it possible for the contact sections to be attached to the man to bring the container surfaces into contact without influencing the locking of the holding edges under the beaded edges.

Auxiliary cutting lines can extend from the main cutting lines to the folding lines. The auxiliary cutting lines run between the cover section and the respective fixing section. The auxiliary cutting lines simplify the angling of the fixing sections in relation to the cover section. Furthermore, guide edges formed by the auxiliary cutting lines on the fixing sections can hold the containers firmly along the rows. For this purpose, the leading edges can lie against the beaded lands of the containers. The guiding edges and the holding edges form functional sections that are separate from one another for laterally guiding or holding the containers. These functional sections, which are separate from one another, can be optimized independently of one another for their respective task.

At least one of the auxiliary cutting lines can run in a straight line and preferably at right angles to the associated main cutting line. As a result, a particularly strong lateral guidance of the containers can be achieved.

Alternatively or additionally, at least one of the auxiliary cutting lines can run at an angle to the associated main cutting line. This can facilitate the removal of the containers from the holding device obtained from the blank. The auxiliary cutting lines can run in a straight line. An angle between the auxiliary cutting lines and the main cutting lines can be at least 120° and/or at most 150°. Alternatively, some or all auxiliary cutting lines can be curved.

A first auxiliary fold line can be formed in the fixing section, which originates at a terminal section of one of the fold lines and runs obliquely to this section of the fold line. The terminal portion of the fold line extends to a free edge of the blank. The first auxiliary fold line makes it easier to bend the fixing section relative to the cover section.

A second auxiliary fold line can be formed in the cover section, which originates at an end portion of one of the fold lines and runs obliquely to it. Preferably, the first and second auxiliary fold lines originate at the same terminal portion of the fold line. The first and second auxiliary fold lines may be configured to fold in opposite directions. The contact of the holding device obtained from the blank on the containers can be further improved by the second auxiliary fold line.

The first and/or the second auxiliary fold line can be formed with embossing, perforations and/or incisions.

A holding device for containers, in particular cans, also falls within the scope of the present invention. The holding device is obtained from a blank according to the invention described above. To obtain the holding device, the blank is folded. The various fold and bend lines described above facilitate the unfolding of the blank into the holder. The advantages described above can be utilized in the holding device according to the invention.

Finally, the scope of the present invention includes a container with a holding device according to the invention as described above, on which containers, in particular cans, are held, with the holding edges of the fixing sections reaching under the beaded edges of the containers and the cover section or cover sections on the containers, in particular the Beaded edges, rests or rest. The advantages described above can be utilized with the container. In order to fix the containers on the holding device, the folding of the blank to form the holding device can take place in whole or in part after the (flat or partially pre-folded) blank has been placed on the containers.

If the contact sections have tabs for connecting the contact sections to one another, the tabs can be fixed to one another, for example glued to one another. As a result, a particularly stable container is obtained. To glue the tabs together, an adhesive can be introduced between the tabs. Alternatively or additionally, an adhesive tape can be applied to the tabs.

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

1 shows a blank 10. A holding device 12 for containers 13 with a beaded edge 14 can be obtained from the blank 10 by folding, compare 2 and 3 . The blank 10 consists of cellulose-containing flat material, here cardboard. The blank 10 is in one piece overall.

The blank 10 has two cover sections 16 . The cover sections 16 can each be arranged on a row 18 of three containers 13 in this case. The two cover sections 16 extend parallel to one another.

Two fixing sections 20 adjoin each of the cover sections 16 . The two fixing sections 20 belonging to a cover section 16 are arranged on opposite sides of the respective cover section 16 . The cover sections 16 and the respective fixing sections 20 are each connected to one another via a fold line 22 . The fold line 22 can be embossed into the flat material and/or can be obtained by perforating the flat material in certain areas. The folding lines 22 each extend in a straight line and are all parallel to one another. The two middle ones, i. H. Fixing sections 20 running between the two rows 18 are connected to one another by a longitudinal fold line 23 .

The fold lines 22 are divided into several sections. A straight main cutting line 24 is formed in the blank 10 between the sections of the fold lines 22 . The main cutting lines 24 completely sever the flat material of the blank 10 . The main cutting lines 24 directly adjoin the cover sections 16 on the one hand and directly adjoin the fixing sections 20 on the other hand. The main cutting lines 24 are arranged offset in relation to the fold lines 22, namely towards the outside as seen from the respective row 18 of the containers 13. The main cutting lines 24 each run straight and parallel to the fold lines 22.

Auxiliary cutting lines 26, 28, 30 run from the main cutting lines 24 to the fold lines 22. The auxiliary cutting lines 26, 28, 30 directly adjoin the cover sections 16 on the one hand and the fixing sections 20 on the other. The auxiliary cutting lines 26 on the two middle fixing sections 20 are straight. The auxiliary cutting lines 26 can run at right angles to the main cutting lines 24 and the fold lines 22 . The auxiliary cutting lines 28 on the outer fixing sections 20 are also straight here. The auxiliary cutting lines 28 run obliquely to the main cutting lines 24 and the fold lines 22. The auxiliary cutting lines 30 on the outer fixing sections 20 run curved. The auxiliary cutting lines 28, 30 can each have extensions which extend essentially perpendicularly to the auxiliary cutting lines 28, 30.

A contact section 32 adjoins the two outer fixing sections 20 in each case. The contact sections 32 and the fixing sections 20 are each connected to one another at a bending line 34 . The bending line 34 can be stamped into the flat material. In the exemplary embodiment shown, the bending line 34 has stamping lines 36 that are curved in sections. The punched lines 36 can partially or completely penetrate the flat material. The punching lines 36 are arranged at the level of the main cutting lines 24 .

The contact sections 32 each have a tab 38 at both ends. When the blank 10 is flat, the tabs 38 protrude in the direction of the rows 18 beyond the cover sections 16 and the fixing sections 20 . The two tabs 38 located at the same ends of the rows 18 can be joined together to stabilize the clip 12 obtained from the blank 10.

At terminal, i. H. A first auxiliary fold line 40 and a second auxiliary fold line 42 are formed in sections of the outer fold lines 22 running to the free edges of the blank 10 . The auxiliary fold lines 40, 42 each run obliquely to the fold lines 22. The first auxiliary fold lines 40 are arranged in the fixing sections 20. FIG. The second auxiliary fold lines 42 are arranged in the cover sections 16 .

To a in the 2 and 3 To get shown container 44, the blank is on the in the rows 18 arranged container 13 placed. The cover sections 16 rest on the containers 13 on the upper side. In the exemplary embodiment shown, the cover sections 16 rest directly on the beaded edges 14 of the containers 13 . Then the middle fixing sections 20 are pressed down along the longitudinal fold line 23 between the containers 13 . A sword, not shown, can be used for this purpose. In addition, the outer fixing sections 20 and the abutment sections 32 are pressed downwards. The contact sections 32 are thereby brought into contact with lateral surfaces 46 of the containers 13 . Finally, the tabs 38 are attached to one another, here by gluing. The tabs 38 also come to rest on the lateral surfaces 46 of the containers 13 .

The containers 13 are essentially cylindrical. Below the beaded edges 14, the lateral surfaces 46 can be conically tapered. The beaded edges 14 protrude beyond the lateral surfaces 46 in the radial direction.

By angling the fixing sections 20 relative to the cover sections 16, the blank 10 opens at the main cutting lines 24 and the auxiliary cutting lines 26, 28, 30. Holding edges 48 are defined on the fixing sections 20 by the main cutting lines 24. The holding edges 48 engage under the beaded edges 14, see also 4 and 5 . As a result, the holding device 12 is latched to the containers 13 . The containers 13 are therefore fixed to the holding device 12 . With respect to a longitudinal axis of the container 13, a displacement of the container relative to the holding device 12 is prevented, namely upwards by the upper side resting of the cover sections 16 on the beaded edges 14 and downwards by the underside contact of the holding edges 48 on the beaded edges 14. Due to the Due to the curvature of the lateral surfaces 46 of the containers 13 about their respective longitudinal axes and the profile of the fixing sections 20 inclined towards the cover sections 16 and the longitudinal axes of the container, the holding edges 48 each lie in their center locally limited on the beaded edges 14.

The auxiliary cutting lines 26, 28, 30 each extend over the beaded edges 14 away. Guide edges 50 formed on the fixing sections by the auxiliary cutting lines 26, 28, 30 fix the containers 13 along the rows 18 by their contact with the beaded edges 14, compare 3 .

At the corners of the holding device 12 , corner regions of the cover sections 20 are bent downwards along the second auxiliary fold lines 42 . The first auxiliary fold lines 40 and the terminal sections of the fold lines 22 make it possible to fold corner areas of the fixing sections 20 under the corner areas of the cover sections 20, compare in particular 3 . On the one hand, this improves the contact of the contact sections 32 with the tabs 38 on the lateral surfaces 46. On the other hand, the holding device 12 is thereby stabilized.

In summary, the invention relates to a blank made of flat material. The blank has at least one cover section with two adjacent fixing sections. A fold line and main cut lines extend between the cover section and each of the fixing sections. The fold lines and the main cut lines extend straight and parallel to each other. The fold lines and the main cutting lines are offset from each other. Retaining edges are formed on the fixing sections by the straight main cutting lines. A holding device can be obtained from the blank by folding. Containers with a beaded edge can be fixed to the holding device so that a container is obtained. For this purpose, the holding edges on the fixing sections reach under the beaded edges, where they bear on the beaded edges in a locally limited manner. The deck sections cover the containers.
