Description

Foldable packaging for cans or the like from a blank.

The invention relates to a packaging for several containers, in particular tins and cans (cans, canisters) or the like from a blank, to a packaging container open on the narrow sides by a single row or a double row of cans or the like is created around.

The invention is particularly applicable to cylindrical containers with metallic closing means, which in the usual way so on the can body are applied so that they form a circumferential bead at each end, the outer diameter of which is larger than that of the can body, so that it protrudes laterally over this. All-metal cans or cans of this last-mentioned construction are generally in use, especially in the food canning industry, however, this type of closure can also be used in containers whose can body is non-metallic, for example consists of a wrapped paper or cardboard tube.

Open packaging for in rows next to or behind one another having the erected, tubular fuselage Pitchers. Canisters, tins. in particular for an edge bead or the like Containers have often been designed in such a way that they consist of a rectangular Cardboard blank or the like that are hinged to one another by means of folding lines Has bottom, side, head or closure part surfaces or fields. It is it is also already known on the end or closure partial surfaces or fields of the blank Closing means in the form of tongues that can be inserted into slots and on the blank fields the edges of the container with the packaging partially receiving slots and foldable. the individual containers in mutual spacing tabs od. the like. To be provided.

Packaging of the last-mentioned type in advantageous and simple Way to make it so that it is filled with containers or cans when carried in the area surrounding the passage of the tabs through the slots with certainty not tear, is the object of the invention.

This object is achieved in that when the latter is packaged According to the invention, the blank at one end is one with a closure field Has a flap connected by a fold line, which when a single row is recorded of containers between their hulls and the side panel set up adjacent to them, also optional when accommodating several rows of containers lying next to each other between their associated reversed hulls while being hinged the opposite end of the blank with one spaced apart each over a flap with hinged tongues is provided which, when recorded a single row of containers to the adjacent side panel, if several are included adjacent rows of containers also optionally to an additional with this side panel hinged closure panel is articulated, each With the packaging open, pull the tongues through along the fold line of the flap of the opposite blank end at a distance from each other provided accordingly Slots can be passed through freely and with their rounded edges that can be folded inwards by 1800 Ends can be placed against the inner surface of the upper edge of an associated container.

Nad has another feature of the invention in a five articulated Fields - closure field, side field, bottom field, side field, closure field - having Cut the middle floor field to a width that is twice the largest diameter of a container to be packaged corresponds to and equal to the sum of the widths of the two outer closure fields.

According to the invention, each of the tongue-receiving elements also extends Slots with the largest part of its width in that of the slots belonging to these slots Tab in the adjacent closure field.

Finally, the invention proposes that the end of each tongue is a Has edge that runs in a curvature that corresponds to the curvature of the inner surface of the bead of the can to be packed.

The measures according to the invention result in known designs of packaging compared to the technical progress achieved that the closing the tongues producing the packaging under play, d. H. freely through the associated Slots can reach through, with the tab assigned to these slots through Grasp the edges of the slots under the raised container edges is, and hereby it is achieved that tensile stresses in the material of the packaging resulting cut does not occur at these points. This in turn provides the advantage that for the production of such packaging also much weaker and cheaper material can be used than is usually given the Weight of the container is necessary to carry it.

According to the invention, one end of the blank in the erected, on the narrow sides of the open packaging anchored by the flap that either between two cans or two rows of cans or between one wall of the package and the adjacent can or row of cans is held, and the other end of the blank anchored by the locking tongue or tongues.

Each of the inwardly folded ends of these tongues pushes from the inside to the upright edge of the corresponding can, causing it to slip sideways the tongue in the direction releasing the other end of the blank and each folded tongue passes through the corresponding slot extends to behind the packaging and is thus held in its blocking position will.

The blank according to the invention can therefore be one on the narrow sides wrapped around a single row or double row of cans in the open package without gluing or stapling by means of wire clips or the like. Required so that the packaging can easily be set up by hand.

Each can is through both the or the peripheral edge or bead receiving slots as well as by a locking tongue, which in the inside of the upstanding edge of the can engages, set against the packaging and is thus secured against longitudinal movements within the packaging.

For those to be set up around a row or a double row of cans Blank according to the invention must have the corresponding ends, i.e. H. Cover and Bottoms of the row of cans with which the locking tongues are to engage, have the required margins. So if the cans to be packed are only on one End with such a border, then they have to be packed before they are packed are, quite uniformly - in each case the upright can edge is directed upwards - be placed side by side. However, one has when applying the invention to cans of food and cans found that such a protruding edge normally occurs both ends of the can is available, so an alignment of the cans, cans or. Like. Practically not necessary at the beginning of the packing process.

When applying the invention to cans with a laterally protruding peripheral edge or bead at both ends of the can, the blank is slit so that the erected Blank has a pair of receiving slots for each of the two ends of each container or, if a double row of cans is provided, each pair of containers of the two Rows.

Furthermore, it is advantageous, regardless of whether the receiving slots are provided for one or both ends of the can, the receiving slots so to arrange that the side walls of the erected packaging between the in the edges or beads surrounding the slits rest against the can walls.

Blanks according to the invention can be made of cardboard, cardboard, corrugated cardboard or similar material are made of relatively low weight, and although the blanks from individual for example by means of stapling or Gluing interconnected parts can be made is recommended manufacture from a single piece that is punched into the desired Shaped and scratched.

Two embodiments of the invention are based on the drawings explained. It shows F i g. 1 shows a plan view of a blank for the production of a on the narrow sides open packaging container according to an embodiment of the invention, FIG. FIG. 2 is a perspective view of one from the blank according to FIG F i g. 1 manufactured, open on the narrow sides packaging for receiving three cans or the like, parts of which are broken away to reveal the interior of the To show the arrangement, Fig. 3 is a plan view of a blank according to a second Embodiment and FIG. Figure 4 is a perspective view of one from a blank according to FIG. 3 manufactured, on the narrow sides open packaging for receiving of six cans or the like, parts of which are also broken away.

Fig. 1 shows a one-piece blank for packaging three Cans of cylindrical shape to form a packaging unit, the cans being uniform have the same metallic terminations, which are applied in the usual way are and at each end a peripheral edge or bead projecting beyond the end closure have, which has a slightly larger diameter than the can body, so that he towers over this side.

The blank has a substantially rectangular shape and is scratched around two fields 1 and 2 forming the sides of the packaging and two bases and to form lid-forming panels 3 and 4 around the end faces and sides of the three To enclose cans.

One end of the blank is formed by a first flap 5, the foldable with the end panel 4, hereinafter referred to as the top panel, is connected and is an extension of the same.

The other end of the blank is also held by a second flap 6 formed, which is foldably connected to the panel 1 forming the side wall and represents an extension of the same.

The tab 6 is provided with three locking tongues 7, which are separated by spaces are separated from each other by the ends of the three cans for simplicity hereinafter referred to as »can tops «Denotes correspond and rest on them. As a result, there are a blank placed around three cans 8 (Fig. 2) the tab 6 and the tongues 7 on the top panel 4, and with the Flap 5 connected to the top panel is then located between the tab 5 forming the side wall Box 1 and the cans.

The top panel 4 has three substantially rectangular slots 9, which, arranged at a distance from one another along its length, incised are through which the locking tongues 7 are pushed. thereby providing an access is made to the tops of the cans. These slots 9 extend laterally over the fold line 10 between the top panel 4 and the flap 5. so that this Tab behind the laterally protruding top edges 11 of the cans 8 detected and also fits tightly against the sides of the cans.

Each tongue 7 is incised transversely at 12, whereby one foldable each End part 13 of such a length is formed that it when it is created when the package is folded inwards by substantially 1800, with its end edge on the inside of the upstanding Vmfangsrandes 11 of the corresponding can strikes or near this comes to rest. The ends of the tongues 7 are slightly rounded in order to be as large as possible To achieve contact with the edges of the can.

Three elongated, spaced apart receiving slots 14, the longitudinal axis of which runs through the middle of the break line or fold line to apparently the fields 1 to 4 forming the wall and on the fold line between the tab 6 and the side panel 1 are provided.

The Aufiiahmesdilitze 14 are aligned centrally with the three to be packed to X. If the packaging is created, cans and result in two slots at each end of each can to the start of the laterally protruding peripheral edges 11. of the cans. The receiving slots extend into the fields 1 and 2 forming the side wall at a distance. which is just enough. to include the can edges so that the side walls of the the exposed packaging touch the flat surfaces of the cans.

To set up the blank around the cans, the three Cans placed on the bottom 3 and their bottom edge bulges in the fold lines between the side panels 1 and 2 and the bottom panel 3 provided receiving slots inserted. The side panels are wrapped around the can sides, and the top panel 4 is folded onto the can tops. The foldable one connected to the top panel The first tab 5 is bent down between the cans and the side wall 1 the laterally protruding edge bulges of the cans into the slots 9 in the top panel be inserted in the first flap 5. The fastenings 7 are thereby through Inwardly turning the end portions 13 folded over by substantially 1800 and through the Slits 9 through into the top panel 4 and behind the top panel 4 of the container held while the ends of the tongues 7 behind the upstanding Grasp the edge beads 11 on the top of the can.

The cans inserted into the folded packaging are made by means of the receiving slots 14 and the locking tongues 7 held and in their position fixed. In addition, the locking tongue con- struktion such that by handling no local twisting or tensile forces occur with the packaging unit. As a result these factors, the blank can be made from a less thick cardboard box, than would otherwise be required.

According to the embodiment shown in Figures 3 and 4 is a blank for packing two rows of three cans each in connection with the first embodiment described type designed. This cut shows also essentially rectangular in shape and is incised transversely and results a field 3 forming the bottom for receiving the bottoms of two cans, two the side walls Forming fields 1 and 2, which are foldable with the opposite sides of the Floor forming field are connected, with each of the fields 1 and 2 the outside a series of cans, and first and second top panels 4 and 15, which are foldably connected to the panels 2 and 1 forming the side walls are. The first of the panels 4 forming the top has a length that is straight sufficient to cover the tops of its three adjacent cans 8, and has a flap 5 foldably connected to the panel extending from one end of the blank is formed. In the erected state of the packaging, the flap 5 is down curved and borders between the two rows of cans. The second top panel 15 has a length that overlaps the first top panel 4 by a small amount, and has three locking tongues, one on each of the first top panel 4 covered box rests.

The first top panel 4 is slit at 9 around the tongues 7 and the slots 9 extend on both sides of the fold lines 10 between field 4 and flap 5 to allow the flap behind the laterally protruding edge beads of the cans 8 summarizes. The tongues 7 are as in first embodiment cross-carved, and the locking arrangement corresponds that previously described, the slightly rounded ends of the tongues being there against the inside of the cans 8 where they abut the other cans 16.

Receiving slots 14 are centered on the fold lines in the same way, as previously described, provided between the fields, however, in this case the cans of each row above and below are only fixed on their outside.

The assembly of the package of this second embodiment takes place essentially in the same way as in the first exemplary embodiment and is therefore not described again.

The packaging container according to FIGS. 3 and 4 can be modified are by the first top panel 4 is widened so that it is the tops both cans covered, the flap 5 then between a side wall of the Packaging and the cans next to it comes to rest.

The locking tongue arrangement can then remain unchanged, or it can Alternatively, the second top panel 15 and the tongues can be omitted 7 can be foldably connected directly to the side panel 1 or be part of a be articulated with this tab connected, similar to the embodiment of FIG F i g. 1 and 2.

The blank shown in Figures 3 and 4 can be modified, to get a bigger or to accommodate a smaller number of cans in each row.

It can also be shortened so that it can accommodate only two Serves cans. In the same way, the shape of the blank of the exemplary embodiment according to the F i g. 1 and 2 can be modified to serve as a package of two, four or to serve more cans arranged in a single row.
