Abstract

The package has a body part (12), and side parts fastened at the body part. The body part is manufactured from a plane, rectangular or quadratic plate part, and folding lines of the side parts limits three sections. The lines are directed from each outer section side to a longitudinal wall. An adjacent section at the wall form a base part. Each side part has a side wall, base plate fixed at the base part and side plates. An independent claim is also included for a method for manufacturing the package.

Description

The invention relates to a package according to the preamble of patent claim 1 and a method for producing a package according to claim 11.

There are packaging, for example, known for fruits and vegetables, which are erected from a single blank, for example, from two- or multi-ply corrugated board. These packages have a bottom part, with this along fold lines connected longitudinal walls and in further fold lines connected to the bottom part side walls. The longitudinal walls and side walls are attached to each other via tabs.

For the production of such packages of different lengths appropriately sized blanks are needed, which involves a considerable amount of equipment and tools.

A generic packaging is made DE 196 02 688 A1 known. It has two side parts, each with a side wall, a bottom flap, two side flaps and a tab-like upper edge part. The side parts are arranged at a distance from each other or directly connected to each other via their bottom flaps and form a double box. About the side panels and the stacked stand-up pouch a lid part is slipped as a slip lid.

It is therefore an object of the present invention to provide a package which can be manufactured at reduced cost in different lengths.

This object is achieved with a package according to claim 1 and with a method according to claim 11.

The packaging according to the invention consists of a body part, which forms a bottom part and longitudinal walls, and two identically formed side parts, which are joined together with the body part and attached thereto. This allows, in a simple way, Produce packaging of different lengths by only the length of the body part changes, but the side panels can remain unchanged.

It goes without saying that for the production of packaging according to the invention the logistics and handling costs as well as the total tooling costs are considerably reduced. In addition, productivity and especially flexibility in development and production are increased. Furthermore, in the case of the packaging according to the invention, it is possible to use different materials for the body part on the one hand and the side parts on the other hand. Thus, the most suitable materials, such as corrugated board, single or multi-waved, plastic or the like, can be used purposefully.

In packaging according to claims 2 and 3, portions of the body part are erected into partitions. Such partitions determine the body part and in particular the bottom parts of extraordinary stability, so that can be used to produce the body part in comparison with dimensioned for the same load conventional packaging thinner materials. For example, when using corrugated board, it is possible to use only single-walled corrugated board if two-shaft corrugated board had to be used in previously known packages. The inventive packaging according to these preferred embodiments thus leads to a considerable saving of material.

The method according to claim 11 for the production of packaging according to the invention is extremely simple.

Preferred embodiments of the packaging as well as the method are indicated in the further dependent claims.

The present invention will be explained in more detail with reference to an embodiment shown in the drawing.

Figures 1 - 4 show a plate member 10 at four different times in the manufacture of a body part 12 shown in Figure 4 from the plate member 10. Figures 5 and 6 show the production of a side part 14 of a side panel blank 16. From a body part 12 and Two side parts 14, a respective packaging 18 is produced, as shown in Figures 7 and 8.

The plate part 10 according to FIG. 1 consists of a rectangular flat blank, in the present case of single-walled cardboard. The longitudinal direction of the plate member 10 is indicated by a double arrow L.

On the plate member 10, for example, by grooves, milling, perforating, etching, scratches, grooves or the like eight extending parallel to the longitudinal direction L and extending over the entire length of the plate member 10 extending fold lines 20. These are shown in dashed lines. These fold lines 20 delimit nine sections, wherein the outermost section on each side is designated by 22, the sections adjacent thereto and the central section by 24 and the two sections located between these sections 24 by 26. The width of the outermost sections 22 is designated by B1. These sections 22 will later form longitudinal walls 28 of the body part 10. The width of the sections 24 is denoted by B2. These sections 24 later form bottom parts 30 of the body part 12. The sum of the widths B2 gives the total width of the body part 12. The width B3 of the sections 26 is greater than the width B1. If the width B3 is greater than the width B1, as in the present case, the partitions 32 have a greater height than the longitudinal walls 28. These heights can however, be chosen arbitrarily. It is only a plate part 10 of corresponding width to keep available and fold lines 20 are formed at correspondingly different locations.

In the manufacture of the body part 12 shown in FIG. 4 from the plate part 10, the outermost portions 22 are erected so that they enclose a right angle with the bottom parts 30 arranged in a plane. As can be seen in particular from FIG. 3, the respectively adjacent sections 26 are erected and at the same time the floor parts 30 are moved toward one another until the respective sections 26 forming a partition wall 32 lie flat against one another, such as this Fig. 4 shows. The erected partitions 32 enclose with the adjacent floor parts 24 at an angle of 90 °. The dividing wall 32 forming portions 26 are secured together, preferably by surface bonding. However, this connection from the respective adjacent sections 26 can also be done in other general ways, such as by hooking, locking or the like.

The dividing walls 32 and the longitudinal walls 28 give the body part an extraordinary stability, so that the floor parts 30 can be loaded considerably without these bending disproportionately.

The side panel blank 16 shown in FIG. 5 has a substantially rectangular section which is intended to form a side wall 34. The side wall 34 is on the one hand - limited in Fig. 5 above - by the edge 36 of the side panel blank 16 and on the other hand by a parallel thereto bottom fold line 38. The lateral boundary is indicated by two side fold lines 40 running at right angles to the bottom fold line 38. The distance between the two side fold lines 40 corresponds to the width B of the body part 12 shown in FIG. 4. The distance of the bottom fold line 38 to the upper edge 36 corresponds to the width B3 - compare FIG. 2 - and thus the height of the partition walls 32nd

Along the side fold lines 40, at the side wall 34 forming portion connect to side tabs 42, which have substantially the shape of an L and which is divided by a Seitenbodenfaltlinie 44. The Seitenbodenfaltlinie 44 extends in a straight line extension to the bottom fold line 38. Along the Floor fold line 38 adjoins the side wall 34 a bottom tab 48 whose width, measured at right angles to the bottom fold line 38, corresponds to the width of the side bottom tabs 46. The bottom flap 48 and the side bottom flaps 46 are separated by a cutout, which has the shape of an isosceles right triangle, this triangle is arranged symmetrically to the extended imaginary sidewall line 40. In the region of the imaginary intersection of the side fold lines 40 with the bottom fold line 38 and the side bottom fold lines 44, the side panel blank 16 has a substantially rectangular cutout 50. This is arranged symmetrically to the side fold line 40 and extends from the bottom fold line 38 by a smaller part in the corresponding side bottom flap 46 and the bottom flap 48 and a greater part in the side wall 34 and the associated side flap 42 into it. The part with which the cutout 50 extends into the bottom flap 48 and side bottom flap 46 is slightly larger than the thickness of the side panel blank 16.

The side panel blank 16 further has at the upper end of the Seitenfaltlinien 40 depending on a direction towards the above projecting stabilizing tongue 52, which is formed opposite the cut 50.

For erecting a side part 14 of a side panel blank 16, the side flaps 42 are erected along the Seitenfaltlinien 40 until they together with the intermediate side wall 34 each include a right angle. Also, as shown in Fig. 6 illustratively, the bottom flap 38 and the side bottom flaps 46 in the direction against the inside, to the Floor fold line 38 and the Seitenbodenfaltlinien 44 erected so that they come to lie in a plane. The cutouts 50 thereby come to lie in the bottom corner areas of the side part 14. Likewise, the stabilizing tongues 52 are located in the upper corners of the side part 14.

The packaging 18, as shown in FIGS. 7 and 8, is now produced by arranging a side part 14 on the body part 12 at its ends lying in the longitudinal direction L. The bottom parts 30 of the body part 12 come to the bottom flaps 48 and the two outer bottom parts 30 also on the side bottom flaps 46 and the longitudinal walls 28 on the inside of the side parts 14 on the side flaps 42 to the plant. The bottom flaps 48 and side flaps 46 are attached to the bottom parts 30 of the body part 12, preferably by surface bonding. Again, this attachment can be done in other well-known manner.

As can be seen in FIG. 8, the legs of the substantially L-shaped side flaps 42, which are perpendicular to the side fold lines 40, measured from the side bottom fold line 44 to its upper edge, have a height substantially equal to the height of the longitudinal walls 28 equivalent.

The partition walls 32 may, as indicated in FIG. 8, have protruding tongues 54. For this purpose, on the plate part 10 - Fig. 2 - at each of the adjacent sections 26 limiting fold lines 20 in one of these sections projecting C-shaped passing through the plate member 10 cuts.

Further, as can be seen in FIGS. 5, 6 and 7, the bottom flap 48 has an erectable tongue 56.

Figures 9 and 10 show, in elevation and side elevation respectively, two similar packages 18 stacked on top of each other, as described above in connection with Figures 1-8. In this case, the stabilization tongues 52 of the packaging 18 arranged below engage in the cutouts 50 of the packaging 18 arranged on top. As a result, a displacement of the two packages 18 is impossible relative to each other, resulting in extremely stable stacks. The side parts 14 of the overhead packaging 18 are supported along the upper edge 36 of the side wall 36 on the side parts 14 of the packaging below. If the partitions 32 have the same height as the side walls 34, the bottom parts 30 of the top packaging are also supported by the partitions 32 of the bottom packaging 18.

It goes without saying that by choosing the length L of the plate member 10 packages 18 of different lengths can be produced. The plate member 10 may thus also have a square shape. With unchanged width of the packaging, regardless of the length L, identically formed side parts 14 can be used.

Of course, it is also conceivable to produce a package 18 without dividing walls 32. In this case, only two folding lines 20 are to be provided on the plate part 10, which delimit two sections 22 and an intermediate section 24. The outermost portion on each side is erected to a longitudinal wall 28, whereas the intermediate portion 24 forms the bottom part 30.

It is also possible to provide only a single partition 32. In this case, five fold lines 20 corresponding to the plate part 10 are provided, which separate six sections from each other, namely two outer sections 22, one adjoining section 24 and two arranged between these sections 26. When erecting these sections 26 then form a partition 32nd , the sections 24 form two bottom parts 30 and the sections 22 form the longitudinal walls 28.

Of course, it is conceivable to provide more than two partitions 32 in a corresponding manner.

It is also possible to dispense with side panel blank 16 on side bottom flaps 46. In this case, however, the side flaps 42 are to be fastened to the longitudinal walls 28. Of course, even in the presence of side bottom flaps 46, the side flaps 42 are secured to the longitudinal walls 28.

It is also possible to divide the bottom flap 48. When the bottom flap 48 is divided or does not extend at least approximately to the side fold lines 40, care must be taken that each bottom part 30 is connected at least in places to the bottom flap 48 or a part thereof.

The package 18 may be provided with a lid.

The apparatus shown in Fig. 11 for erecting and assembling of packages 18, as above are described, has five stations. As seen in the direction of production P, a deformation station 58 follows a folding station 60 for the production of the body part 12. These follow in succession a first assembly station 62 and a second assembly station 64 for the assembly of a first and second side part 14. The last station provided is a transfer station 66. which transfers the finished package 18 to a stacker or outfeed conveyor.

The deformation station 58 has on the width of the plate parts to be processed 10 adjustable side stops 68. These center the by means of a conveyor 70, such as a belt conveyor, supplied plate member 10. If the transport of the plate members 10 by means of a vacuum transport device, the plate members 10 are briefly released in the region of the side stops 68 to align them.

The side stops 68 are followed in the production direction P by the deformation unit 72. In the present case, this has a groove, milling or perforation disk 76 arranged at a location at right angles to the direction of production P, rotationally driven shaft 74 at the locations of the folding lines 20 to be produced. During transport of the plate part 10 through the deformation unit 72 through the fold lines 20 are generated at the desired locations.

Subsequently, the further transport of provided with the fold lines 20, one-piece plate member 10 in the folding station 60. This has Aufrichtklappen 78 in order to fold on each side of the outermost portion 22 by 90 ° to a longitudinal wall 28. Next, the Aufrichtklappen 78, as indicated by the arrows 80, movable toward each other to erect the sections 26 to partitions 32 by moving the bottom parts 30 towards each other. Further, the folding station 60 to adhesive applicators 82, which provide the sections 26 in the desired areas with adhesives. Further, the folding station 60 may be provided with pressing elements which press together on both sides from above each of the dividing wall 32 forming portions 26 together until the bond is formed.

Subsequently, the transport of the body part 12 formed in the folding station 60 in the first assembly station 62. This has a device 84 to rotate the supplied with their running in the production direction P longitudinal direction L body parts 12 about a vertical axis by 90 °. Side of the rotator 84 a Seitenenteilfaltvorrichtung 86 is arranged. A transport device indicated by the part 88 leads in each case to a side panel blank 16 to further adhesive application elements 82 which attach adhesive to the bottom flap 48 and the side bottom flaps 46.

The transport device indicated by the arrow 88 brings the adhesive-provided side panel 16 to a folding device 90. This folds the side panel blank 16 along the side fold lines 40 by 90 ° with well-known elements and places the side panel blank 16 such that the side wall 34 in FIG a vertical plane which runs parallel to the production direction P. In the folding device 90, the adhesive bottom flap 48 and side bottom flaps 44 are further folded into a horizontal plane. The side panel blank 16 is with dash-dotted lines and the finished part 14 shown in solid lines.

As indicated by another arrow 88 ', the side member 14 is moved toward the body part 12 until the side wall 34 abuts the body part 12. Subsequently, the side part 14 is raised, so that the bottom flap 48 provided with adhesive and side bottom flaps 46 come into contact with the bottom parts 30 of the body part 12. Advantageously, pressing members are provided to press the bottom flap 48 and side bottom flaps 46 and the bottom parts 30 of the body part 12 together until the adhesive connection is established.

The equipped with a side part 14 body part 12 is then supplied in the production direction P of the second assembly station 64. This has a mirror image of the Seitenenteilfaltvorrichtung 86 formed side panel folding device 86 'on. In exactly the same way as described above, here a second side part 14 is erected, arranged on the body part 12 and glued to it. The finished package 18 is then transported in the production direction P to the transfer station 66.

It is conceivable to provide a filling station between the first assembly station 62 and the second assembly station 64 in order to fill the body part 12, which is provided only with a single side part 14, with the product to be packaged.

It is also possible to arrange the two Seitenteilfaltvorrichtungen 86, 86 'at the rotator 84 opposite to each other.

The two side parts 14 are then attached to a body part 12 at the same time.

Also, only a single side-part folding device 86 can be provided. After the assembly of the one side part 14, the body part 12 is then rotated by 180 ° by means of the rotating device 84, after which the other side part 14 is mounted by means of the side folding device 86.

If the corresponding parts do not stick together, the device need not have adhesive applicators 82, 82 '. It then has stapling, welding, ultrasonic or other well-known units for the preparation of the compounds in the corresponding stations.

The inventive packaging 18 can be produced fully automatically in a simple manner. In particular, packages 18 of different lengths can be produced in the same device, whereby only the settings dependent on this length are to be made.
