Description

The present invention relates to a carrying device for containers, especially bottles. The support device is formed from a one-piece blank of sheet material which can be folded and it comprises two side walls and a bottom, which is hinged to one side wall and divided longitudinally by means of a folding line and whose free edge can be connected to the other side wall by using a bottom connection lask. Furthermore, the device comprises short wall halves which are hinged to the other, opposite edges of the side walls and a short wall flap, which is hinged to the short wall halves on one side of the longitudinal walls, parallel to the fold line, where the two short wall flaps are connected to each other via a connecting part which is divided across a fold line and extending over the short wall halves. To the other short wall halves, there are, parallel to the folding line, hinged longitudinal step parts, which are provided with first handle parts which are hinged to each other on the sides facing each other. In addition, two transverse steps are punched out in each longitudinal step section, which are hinged to the relevant cross step and are provided on their free edge with hinged cross step connection tabs that can be connected to the assigned side wall, the cross step connections for one cross step being hinged around a folding line that coincides with the folding line for hinges of the other crossbars. The device further comprises other, mutually hinged handle parts which, by folding and pre-shaping, can be folded against the aforementioned first handle parts and connected to them.

Such a cut blank for a carrier device for containers

is known (DE-OS 34 02 729). The support device formed by this item comprises a longitudinal step and to this hinged transverse step which is connected to the longitudinal walls, preferably by gluing. In this way, as a rule, three rooms will be formed on each side of the longitudinal step for receiving containers, especially bottles. The handle, which is connected to the longitudinal step, protrudes over the long and

the upper edges of the short wall, so that a convenient carrying option is also ensured when the device accommodates containers.

The support devices are designed in advance by each subject

in one piece in such a way that the carrier device after pre-design or adhesive can be folded into a flat shape. In this state, the carrier devices are delivered from the manufacturer to the user, who then assembles the carrier devices in their final form and e.g. fill them with bottles. For this purpose, the short walls can be folded in height. The bottom can be folded around a longitudinal, central fold line. With flat-lying support devices, the side walls are placed on the longitudinal step, while one short wall is folded outwards and the other inwards. The bottom also folds outwards.

In a flat state, the support devices naturally have several layers of material lying on top of each other. However, known carrier devices have the disadvantage that the number of material layers is different over the surface of the device. Areas with six material layers alternate with areas with two and four layers. Such an uneven distribution of the material layers is fraught with significant disadvantages.

A disadvantage is that the volume taken up by a flat carrier, e.g. in an outer packaging or in the magazine of a packaging machine, is determined by the highest number of material layers. The known carrying devices for containers thus occupy a relatively large volume. As is known, this volume affects the transport and storage volume and thus the transport and storage costs.

When pre-designing, parts of the subject that are to be connected to each other are usually glued together. In order for an effective joining to be achieved, the joined parts must be put under pressure for a certain period of time. However, it is difficult to exert even pressure against the parts to be glued together due to the uneven distribution of the layers. If a uniform pressure is to be achieved against the surface which is to be put under pressure at all times, a significant constructive effort is required which is not commensurate with the standard of gluing machines.

As mentioned above, the flat carriers are erected in the packaging machine and filled with containers. The supply to the packaging machine takes place appropriately

from a magazine. Carrier devices for containers with an uneven distribution of the material layers result in a skewed stack, which makes feeding into the packaging machine difficult. Due to the skewed stacking, the magazine can only have a certain length.

The present invention is based on the task of improving the carrying device for containers of a blank in one piece of foldable material, so that an even distribution of the materials is achieved.

This task is solved according to the invention by the fact that the other handle parts are hinged to the connecting part, that the free edge of the cross steps faces the assigned short wall half,

that the connecting flaps of the transverse steps which are closest to the short-wall halves are punched out of the cross-step material and are connected by a cross-step flap part whose free edge facing the short-wall half roughly coincides with the fold line between the longitudinal step part and the short-wall half or is partially punched out that the material of the assigned short wall halves and is hinged to the transverse step via a fold line which runs parallel to i at a distance from the fold line between the short wall half part and the longitudinal step part. In the preliminary design, the first handle parts can be folded about the fold line between the short wall half and the side walls towards the other handle parts and the short wall flaps for the other short wall halves are foldable about their fold lines to the short wall halves against the short wall halves and a part of the other handle parts. The thus folded parts are thereby at a distance from each other at the edges that face each other or the edges will lie butt-in-butt in height.

It turns out that such a construction of a blank in one piece for a carrier rooting for containers makes it possible to fold it into a flat-lying carrier device, where an even distribution of the material layers is achieved, i.e. throughout four material layers with the exception of the bottom, which is not critical. The even distribution of the layers without this being at the expense of stability and load-bearing capacity, provides significant advantages.

By gluing together the blank for pre-shaping, an even pressure distribution is achieved. A single and undivided pressure tape can be used to achieve sufficient adhesive pressure.

The material volume of the flat carrier device for containers according to the invention is reduced by a third compared to conventional carrier devices for containers. Consequently, several carrying devices go in an outer packaging carton for storage and transport of the carrying devices from manufacturer to user. A significant saving in costs for storage and transport is thus achieved.

The even distribution of material layers enables impeccable ma-gas stacking of the flat-lying containers in the packaging machine. Compared to known carrier devices, a greater number of carrier devices can be placed in a magazine of a given length. For a given number of containers, the length of the magazine can be reduced.

In addition to these significant advantages, material savings are also achieved with the carrying device according to the invention, compared to known items.

With regard to the subject of the carrier device for containers according to the present invention, there are two possibilities when it comes to the design of the transverse steps of the longitudinal step part. At one, the free edge of at least one cross-step connecting batten abuts the fold line between the longitudinal step part and the adjacent short wall half. Thereby, the rooms on this short side are of course extended by the slot width and are no longer exactly square. However, this does not seem unfortunate when it comes to protecting bottles.

The other possibility is that the transverse steps facing the assigned short wall halves engage partially in the short wall halves with their connecting tabs. In the case of an upright carrying device, openings will then be formed on the short side. However, these openings can be made very small, if, according to a continuation of the invention, two flap parts are hinged to the crossbar coaxially and at a distance from each other and if the connecting flaps are connected to the flap parts via arms. Only a relatively small amount of material can then be removed from the short wall halves so that a firm connection is still achieved between the corresponding transverse step and the longitudinal wall. The openings in the short walls in the case of an upright carrying device will therefore be of a slot-like type and will therefore not have any adverse influence on the overall external impression of the carrying device for containers.

It will be particularly advantageous if the lask parties to them

two transverse steps according to another continuation of the invention are staggered with respect to the short wall halves. The displacement is such that the individual recesses that appear in the short wall halves will neither completely nor partially cover each other. In this way, four slit-like openings located one above the other will appear above the fold line in one short wall.

The invention shall be described in more detail below with reference to the drawing where

fig. 6 is a representation similar to FIG. 2, but where the cross-step connecting flaps have a different position, and

fig. 7 schematically shows the room division in the original embodiment according to fig. 6.

Before we go into more detail on the details shown in the drawing, it is mentioned that each of the mentioned features on its own or in connection with features specified in the claims is of significant importance for the invention.

Regarding fig. 1 and 2 it should be noted that cut or punch lines are shown with continuous lines and fold lines are shown as dashed lines.

The subject shown in fig. 1 has two longitudinal walls 10,11. On the outside of the longitudinal wall 10, a bottom 12 is hinged via a folding line, which is divided and foldable by means of a folding line 13 which runs lengthwise in the middle of the bottom. At one end of the folding line 13 there is a triangular recess 14. To the other, opposite sides of the longitudinal wall 10, the short wall halves 15, 16 are hinged via a folding line. To opposite sides of the longitudinal wall 11, the short side halves 17, 18 are hinged via fold lines. To the outside of the longitudinal wall 11, a bottom connecting flap 19 is hinged via a folding line. To the short wall halves 15, 17, the connecting flaps 20, 21 are hinged via folding lines. The short-wall connecting strips 20,21 extend over the height of the short-wall halves 15, 17 and are connected to each other via a connecting part 22 which is divided in the middle across a fold line 23.

Longitudinal step sections 24,25 are hinged to the short wall halves 16,18 via folding lines. The step parts 24, 25 have handle parts 26, 27 with handle openings 28, 29. The handle parts 26, 27 are connected via a folding line 30. On the outside of the step parts 24, 25, hook parts 31, 32 are formed, which, when supported upright, lie above each other and engage in the recess 14 in the bottom 12. However, such a feature is in principle known.

In the step parts 24, 25, two transverse steps 33, 34 are punched out, respectively. 35, 36 and are hinged to the material in the longitudinal step portions 24, 25, as shown in fig. 1. The fold lines mentioned, which are not provided with reference numbers, run parallel to each other. Via a fold line, a cross-step connection strap 37 or 38 the hinge for the cross step 33 and 35 respectively. The relevant fold line is on the same line as the fold line for the cross steps 34 and 36 respectively. The connecting strip 37 and respectively. 38 is thus completely punched out of the material in transverse steps 34 and 36 respectively. 2. The connecting flap has a part 40 which is cut out of the transverse step 34 and with which two slightly diverging arms 41, 42 are connected. The arms extend in the direction of the fold line 43 between the longitudinal step part 24 and the short wall half part 16. The arms 41, 42 are connected to parts 44, 45, which have their longitudinal extension in the direction of the fold line 43. The parts 44, 45 are partially punched out of the material in the short wall half part 16. In the example shown, they protrude 2.5 mm into the short wall half part 16.

On the opposite side, the parts 44, 45 are via folding lines 46 respectively. 47 is hinged to the cross step 34. The cross step connecting strap 39 can thus be swung around the folding line 46, 47 opposite the cross step 34 for connection with the assigned longitudinal wall 10. The same of course applies to the cross step 36. It will be obvious that the parts 44, 45 must be staggered inwards or outwards opposite the ends of the arms 41, 42, so that a connection of the connecting flap 39 with the transverse step 34 is achieved. Via folding lines, other handle parts 48, 49 are hinged to the connecting part 22. They include handle holes 50, 51, as in the case of an upright carrying device works together with the handle holes 28,29.

The preliminary design of the subject according to fig. 1 to a flat-lying carrier device for containers will appear from fig. 3 and 4, which will be discussed below.

The part of the subject according to fig. 1 which is to the right of

the fold lines between the longitudinal walls 10, 11 and the short wall halves 16, 18 are folded around said fold lines to the left on the remaining part, as indicated by the

dashed arrow 52. Furthermore, the short-wall connecting strips 20, 21 are folded around the assigned folding line towards the right towards the mentioned lower part, as indicated by the dotted arrow 53. Between the free edge of the step parts 24, 25 and the free edge of the connecting strips 20, 21 is formed a small distance. The thus folded part is folded around the fold line 30 or the fold line between the handle parts 48, 49, as indicated by the dashed arrow 54 in fig. 4. In fig. 1, with the help of hatched surfaces it is indicated which areas should be applied with glue. At first

folding according to fig. 3, the areas to which glue has been applied are glued together. The handle parts 26,27 are then glued together with the handle parts 48,49. Furthermore, the transverse steps 33-36 are glued together via their connecting tabs with the inside of the longitudinal walls 10 and 11. The connecting tabs 20, 21 are glued together with the handle parts 48,49. In the phase shown in fig. 3 additional glue is applied, so that at any time one longitudinal step part 26 or 27 is provided with glue, however excluding the cross steps 33-36. Furthermore, glue is placed on the outside of one of the connecting strips 20 or 21. Finally, the base 12 is given a coat of glue in one batch.

After gluing, which occurs in connection with the rendering as shown in fig. 4, a completely flat carrier for containers is formed, which, apart from the base 12,

has four layers throughout, as will be seen from the figures. In the case of the flat-lying support device, the short wall halves are 15, 17

folded outwards and located above each other, while the short wall halves 16, 18 are folded inwards between the longitudinal walls 10,11. When the device is erected into a finished carrying device for containers according to fig. 5, the short wall halves 15-18 are folded up. In this way, the bottom 12 is also folded out. The hooks 31,32 can grip under the bottom in the area of the outlet 14 and stabilize it in this position, until the device is filled with bottles. Fig. 6 shows a rendering similar to fig. 2. The same reference numbers have therefore been used, which are provided with ' signs. It will be seen that the flap parts 44' and 45' for the cross-step connecting flap 39<1> in their free edge coincide with the fold line 43' of the long step part 24'. In this way, you avoid the slits in the card wall, as shown four times in fig. 5. In order for this to be achieved, however, the long sides and the long step part in this area must be extended approximately by the length that the parts 44 and 45 corresponding to fig. 2 protrudes into the short wall half part 16. This is evident from fig. 7. In fig. 7 shows in cross-section a room division which will be formed by an embodiment according to fig. 6. There are four square rooms 50 with a size of 66 x 66 square meters. Two rooms 51 have a length of 70 mm. The bottles that are recorded are shown with their bottom circumference. It will be seen that the bottles 52 have some clearance in the spaces 51 in the longitudinal direction. However, this will not have any adverse influence on the protection effect for the bottles.

Otherwise, the same applies to a subject with an embodiment according to fig. 6 which is mentioned regarding other features of the subject according to fig. 1-3.
