DE19716296A1 - Stackable cardboard packing to fit round cylindrical cans - Google Patents

Abstract

The packing has a rectangular frame folded from a cardboard strip with upper and lower endface parts of a width matching the diameter of the cans and covering their ends. The endface frame parts (11,12,41,42) have small cuts (24,24,26,45,46) forming folding tabs (27,28,47). At least one wedge (7-10) and two tabs are allocated to each two adjacent cans (4,5), resting against the wedge gap left by the two adjacent cans. One tab (27) is stuck to its cans, preferably by hot-melt spot gluing.

Description

The invention relates to a stackable cardboard packaging for several spaced apart in a row and Wedge-forming cylindrical cans, with one made of one Cardboard strips folded rectangular frame, with top and lower front frame parts, the width of the diameter corresponds to the cans, the ends of the cans and with a coat side frame parts the outer surface lines of the in the row covers outer cans and at least on the end faces is immovable, so that the cans with the frame one to Handle form a sufficiently stable unit.

In such a case, the applicant does not print it known cardboard outer packaging are the top end faces in the Frame glued in. This creates a sufficiently stable Packaging unit, in particular for cans with a rectangular shape Cross-section, but because of the adhesive material are such cans not suitable for drinking directly from them.  

In another, the applicant also not printed Lich known prior art is the lower front Frame part widened and folded up on both sides, so the frame in the lower area on which the cans get up, is box-shaped. Because of the lack this sales unit is not special in terms of gluing stable. A wider cut is also required.

The invention has for its object, starting from the beginning mentioned prior art, without additional cardboard material to form a sufficiently stable unit that allows to drink straight from the can.

The object is achieved in that on the front frame share tabs that can be folded over with small side incisions are formed and that at least one wedge gusset each two Adjacent cans have at least one tab assigned to them the two cans forming the respective wedge gusset.

Through such tabs, each can is at least once, be it held up or down or left or right. It arises a sufficiently stable and stackable sales package, at which the cans themselves contribute to stability. The pack volume is not increased, there is no additional cardboard material needed. The end faces of the cans are not glued, so that can be drunk straight from the can.

In one embodiment it is provided that all frame parts, apart from the side incisions, one continuous have the same width. You come without any Material waste, and the production is particularly inexpensive stig.

In another version, the width is the front Frame parts larger than the width of the shell-side frame parts.  

This does result in a certain waste of material, whereby however the largest width of the cardboard strip is no greater than in the previously mentioned variant. The latter version is more appealing in your presentation because even if many cardboard boxes are stacked next to each other Look at the round can shape from the narrow side is.

The sales package is particularly robust if both end frame parts on each wedge gusset with one each Are provided. So every single gusset is A tab is assigned to both the top and bottom. Next the particular stability results in the advantage that if several sales packages are stacked side by side, one seized individual unit from above with the fingers and removed can be.

However, less effort is alternatively possible by alternating after each can, the tabs once on the top and once on the lower front frame part. This makes each can, with the exception of the two outer cans, the Row, held in the area of both ends by tabs. The outer cans, however, are due to the shell-side frame parts stabilized enough.

It is also useful if in this case the tabs after each can changes, once on the left and once on the right of each Leagues front frame part are provided. The tabs are then alternately at the top left and bottom right. This creates a cardboard outer packaging, even with something robust handling is still sufficiently stable. For the preferred case that the unit consists of three cans, there is two tabs, one in the gusset gusset at the top left and one in the next wedge gusset at the bottom right of the cardboard outer packaging.  

The production of the sales unit is particularly easy if the flaps are point-glued using hot-melt. Alternative is it is of course possible within the scope of the invention, the respective Tab through an adhesive strip in its folded position to keep.

So that the flaps of the sales pack do not look too much affect, is both the tab length and the Tab depth at most a quarter of the width of the cardboard strip.

In a particularly preferred embodiment of the invention Tabs formed by trapezoidal incisions, whereby the smaller trapezoidal edge is the folded edge. This creates on the one hand an adequate surface contact of the tabs with the Coating the cans when gluing, and second comes when Sliding two cardboard packaging over one another no snagging on the areas of the tabs.

A suitable one is also used for the outer carton packaging Cutting, whereby a coherent cardboard strip is drawn is cut, the total length of which is the sum of the partial lengths of the two front frame parts and the two shell side Frame parts plus a narrow overlap strip corresponds, with the four frame parts as well as the one at one end overlap strips each of the cardboard strip are separated from each other by folded edges and the die Cut-making incisions cut to the fold-over edge are. In the case of a cut variant, the cardboard strip has consistently the same width. With another Zu cut variant corresponds to the width of the front Frame parts the diameter of the cans, while the width of the shell-side frame parts is smaller than the diameter of the Cans.  

Finally, a method for producing the is claimed Cardboard outer packaging, in which the cardboard strip as a frame the cans arranged side by side is folded, one Overlap strips combined with a frame part on the casing side which is, and in which the flaps are folded and in each case associated wedge gusset area applied to the cans will.

Further advantages and features of the invention result from the following description of two embodiments.

Fig. 10 in a reduced representation of a blank for the cardboard outer package of Fig. 6.

The stackable cardboard outer packaging 1 according to FIGS. 1 to 3 contains a rectangularly folded frame 2 , which is made from a cardboard strip 3 (see FIG. 5). With this cardboard outer packaging 1 , a plurality of cylindrical cans, preferably three cans 4 , 5 and 6 , arranged side by side in a row, are combined to form a relatively stable sales unit. The cans 4 , 5 and 6 thereby form wedge gussets 7 , 8 , 9 and 10 .

The cans 4 , 5 and 6 are preferably beverage cans made and filled from cardboard, the upper end faces 13 , 14 and 15 of which, in a manner not shown, are provided with a closable filling opening which, after opening, is also to be used as a drinking opening.

The cardboard strip 3 has a continuous width B, which corresponds to the diameter D of the cans 4 , 5 and 6 . As a result, an upper end frame part 11 covers the upper end faces 13 , 14 and 15 and a lower end frame part 12 covers the lower end faces 16 , 17 and 18 of the cans 4 , 5 and 6 . Shell-side frame parts 19 and 20 of the rectangular frame 2 cover the outer surface lines 21 and 22 of the outer boxes 4 and 6 .

So that the cardboard outer packaging 1 becomes a stable and easy to handle sales unit, small lateral incisions 23 , 24 and 25 , 26 are provided in the upper and lower frame parts 11 and 12 in the area of the wedge gussets 8 and 9 . With these small incisions 23 , 24 and 25 , 26 , two foldable tabs 27 and 28 are formed, of which the tab 27 is arranged at the top left in FIG. 1 and the tab 28 at the bottom right in FIG. 1. These tabs 27 and 28 are folded around folding edges 29 and 30 by approximately 90 ° and glued to two adjacent cans 4 , 5 and 5 , 6 , respectively, by means of hot-melt point bonding 31 and 32 (see in particular FIG. 2).

Regardless of whether the sales unit is three cans, possibly only two cans or even four and more cans, it is expedient to provide the tabs 27 and 28 alternately at the top and bottom and left and right. Each can 4 , 5 , 6 . . . should be held at least once by a folded and glued tab 27 , 28 .

Because of the tabs 27 and 28 , both the upper end frame part 11 and the lower end frame part 12 are immovably on the upper end faces 13 , 14 and 15 and on the lower end faces 16 , 17 and 18 of the cans 4 , 5 and 6 . The cans 4 , 5 and 6 and the frame 2 thereby form a unit that is sufficiently stable to handle, without any additional material on the cardboard strip 3 and without adhesive components in the drinking area of the cans 4 , 5 and 6 .

From the enlarged representation according to FIG. 4 it can be seen that the flap length a and the flap depth t are at most a quarter of the width B of the cardboard strip 3 . Since Lichen incisions 23 and 24 - as well as the other incisions 25 and 26 not shown here - are arranged obliquely, so that trapezoidal tabs 27 and 28 are formed, the smaller trapezoidal edge being the folding edge 29 .

As can be seen from FIG. 5, the blank for the cardboard outer packaging 1 consists of an overall coherent cardboard strip 3 , the width B of which corresponds to the diameter D of the cans 4 , 5 and 6 . The later position of the cans 4 , 5 and 6 is indicated by dash-dotted lines in FIG. 5.

The total length L of the cardboard strip 3 consists of four partial lengths l ₁ , l ₂ , l ₃ , l ₄ and a narrow overlap strip 33 of length s (see also FIGS. 1 and 2). This overlap strip 33 is glued to the casing-side frame part 20 when folding the frame 2 .

The partial lengths l ₁ and l ₃ correspond to the upper front frame part 11 and the lower front frame part 12 . The two other part lengths l ₂ and l ₄ correspond to the shell-side frame parts 19 and 20 . There are preformed folded edges 35 , 36 and 37 between the frame parts 11 , 12 , 19 and 20 mentioned . A corresponding folded edge 34 is provided between the upper end frame part 11 and the overlap strip 33 .

It should also be mentioned that in the cutting, the oblique cuts 23 , 24 , 25 and 26 reach up to the associated folding edge 29 , 30 .

The corresponding to FIG. 5 formed blank is as a frame 2 around the adjacent cans 4, 5 and 6 folded, wherein the overlap strip 33 is connected to the shell side frame members 20. The tabs 27 and 28 are folded over and glued to the cans 4 , 5 and 6 in the area of the respective associated wedge gusset 8 and 9 .

The stackable cardboard outer packaging 38 according to FIGS. 6 to 8 also contains a rectangularly folded frame 39 , which is made from a slightly differently cut cardboard strip 40 (see FIG. 10). Also with this cardboard outer packaging 38 , several spaced apart in a row angeord designated cylindrical cans, preferably three cans 4 , 5 and 6 , are combined to form a stable sales unit. The cans 4 , 5 and 6 again form wedge gussets 7 , 8 , 9 and 10 . These cans 4 , 5 and 6 are made of cardboard and filled abge beverage cans, the upper end faces 13 , 14 and 15 are provided in a manner not shown with a closable filling opening that can be used as a drinking opening after opening.

In this embodiment, the cardboard strip 40 has a width B which corresponds to the diameter D only in the area of the end faces of the cans 4 , 5 and 6 . The folded frame 39 covers the upper end faces 13 , 14 and 15 with an upper end frame part 41 and the lower end faces 16 , 17 and 18 of the cans 4 , 5 and 6 with a lower end frame part 42 . Shell-side frame parts 43 and 44 cover the outer skin lines 21 and 22 of the outer cans 4 and 6 .

Notwithstanding the cardboard outer package 1 according to Fig. 1-overpack box 38 of FIG. 6 is provided in that each individual wedge a gusset 7, 8, 9 and 10 at both the top and bottom 47 is assigned in each case one tab. This flap 47 is again formed by side incisions 45 , 46 and an associated folding edge 48 , just as in the previously described embodiment. This not only leads to an even more robust cardboard outer packaging 38 , but also makes it possible to grasp and lift out a single one from above of several cardboard outer packaging 38 stacked side by side.

All tabs 47 can, as already described above, be connected to the associated cans 4 , 5 and 6 by a hot-melt point bond 31 and 32 . In the embodiment of FIG. 6, however, shown that, alternatively, an adhesive tape 49 which is preferably self-adhesive, can be placed over the individual tabs 47, so that the tabs 47 are not on the cans 4, 5, and adhered 6 but are only forced to invest in them. It can be provided that a continuous adhesive strip 49 is completely wrapped around the mutually associated wedge gussets 7 , 9 and 8 , 10 , as shown in dotted lines in FIG. 6.

Such adhesive strips 49 can of course also be provided in the embodiment according to FIG. 1.

Also in the embodiment of Fig. 6, it is irrelevant whether it is in the sales unit at two doses, three doses or is more than three doses.

Due to the tabs 47 , both the upper end frame part 41 and the lower end frame part 42 are again immovably on the upper end faces 13 , 14 and 15 and on the lower end faces 16 , 17 and 18 of the cans 4 , 5 and 6 . The cans 4 , 5 and 6 and the frame 39 thereby form a very stable unit for handling, again without any Mehrma material on the cardboard strip 40 and without adhesive components in the drinking area of the cans 4 , 5 and 6 .

Deviating from the embodiment of FIG. 1 is in the embodiment of Fig. 6, the width B of the front frame parts 41 and 42 is greater than the width b of the shell side frame parts 43 and 44. However, it should be expressly mentioned that the different widths B and b could also be present in the embodiment according to FIG. 1 or that a continuously constant width B could be used in the embodiment according to FIG. 6.

The smaller width b along the casing-side frame parts 43 and 44 results in a certain material waste on the cardboard strip 40 , but on the other hand leads to an even more appealing cardboard outer packaging 38 in which, for example, the round shape of the cans 4 , 5 from the narrow side and 6 remains recognizable even when many cardboard outer packaging 38 are stacked close together. This can be seen, for example, from the illustration in FIG. 9.

As can be seen from FIG. 10, the blank for the cardboard outer packaging 38 also consists here of an overall connected cardboard strip 40 , the width B of which, as already explained, only partially corresponds to the diameter D of the cans 4 , 5 and 6 speaks. The larger width B is located on the end frame parts 41 and 42 , the smaller width b on the shell side frame parts 43 and 44 .

The total length L of the cardboard strip 40 again consists of four partial lengths l ₁ , l ₂ , l ₃ , l ₄ and a narrow overlap strip 50 of length s' (see also FIGS. 1 and 2). This overlap strip 50 is glued to the casing-side frame part 43 when the frame 39 is folded. The folding direction of the blank according to FIG. 10 is therefore somewhat different from the folding direction of the blank according to FIG. 5.

From Fig. 6 it can be seen that the overlap strip 50 is held on the associated frame part 43 in the cardboard outer packaging 38 folded into a frame 39 by means of a dash-dot line, glued on from the outside, adhesive strip 51 .

As can be seen, the partial lengths l ₁ and l ₃ correspond to the lower end frame part 42 and the upper end frame part 41 . The two other part lengths l ₂ and l ₄ correspond to the shell-side frame parts 44 and 43 . Between the said frame parts 41 , 42 , 43 and 44 there are preformed folded edges 52 , 53 and 54, respectively. A corresponding folding edge 55 is provided between the lower end frame part 42 and the overlap strip 50 .

Also in the blank according to Fig. 10, the oblique cuts are brought to 45 and 46 to the associated fold-over edge 48th The tabs 47 are also trapezoidal here.

The corresponding to FIG. 10 formed blank is as frame 39 where the overlap strip 50 is connected to the shell side frame part 43 around the adjacent cans 4, 5 and 6 folded. The tabs 47 are folded over and applied to the cans 4 , 5 and 6 in the area of the respective associated wedge gusset 7 , 8 , 9 and 10 .
