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

Packaging and procedure for its production.

The present invention relates to a packaging, according to the preamble of claim 1, and to a method for the manufacture of a package according to claim 11.

Packaging is known, for example for fruit or vegetable, which are raised from a single cut, by example of corrugated cardboard with two or more layers. These packages they have a piece of floor, with connected longitudinal walls with this along fold lines, and side walls connected, with other folding lines, with the floor piece. The Longitudinal walls and side walls are fastened between Yes through wings.

For the manufacture of packaging of this type of different lengths are needed sized cuts corresponding, which entails a significant expense in machines and tools

A generic packaging is known thanks to document DE 196 02 688 A1. This one has two side pieces each one with a side wall, a bottom wing, two side wings and one upper edge piece of wing type. The side pieces are arranged at a distance from each other or directly connected each other using their bottom wings and form a double drawer. On the side pieces and flat bottom bags stacked inside are turn a lid piece upside down as a bell-type lid.

The present invention therefore raises the problem of creating a package, which can be manufactured with different lengths with reduced costs.

This problem is solved with a packaging according to claim 1 and with a method according to claim eleven.

The packaging according to the invention consists of a body piece, which forms a piece of floor and walls longitudinal, as well as its side pieces, formed identical, which are attached to the body part and are subject to it. This allows, in a simple way and way, manufacture packaging of different lengths, thanks to the fact that it varies only the length of the body part, while the Side pieces remain unchanged.

It is understood by itself, that for the manufacture of packages according to the invention are remarkably reduced logistics and handling complexity as well as Total tool costs. In addition, the productivity and, in particular, flexibility in development and production. In addition, there is in the packaging according to the invention, the possibility of using different materials for the piece of body, on the one hand, and for the side pieces, on the other. From this way you can selectively use the materials more suitable as, for example, corrugated cardboard, one or more waves, plastic or similar.

In packages according to claims 2 and 3 sections of the body part are raised to give separation walls. Separation walls of this type give the body part and, in particular, its floor pieces an extraordinary resistance, so that, compared to conventional packaging sized for the same load, thinner materials can be used for body part manufacturing. In this way it is possible, for example in the case of corrugated cardboard, to use only corrugated cardboard of one wave, when in previously known packages, corrugated cardboard of two waves had to be used. The packaging according to the invention, according to these preferred embodiments, therefore leads to a significant saving of
material.

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

Preferred embodiments of the packaging as well as the procedure are indicated in the remaining subordinate claims.

The present invention is explained in greater detail. detail based on an exemplary embodiment represented in the drawing.

Figures 1-4 show a plate piece 10 in four different instants during the manufacture of a body part 12, shown in Figure 4, from the plate piece 10. Figures 5 and 6 show the manufacture of a side piece 14 from a part cutout side 16. From this body part 12 and two pieces lateral 14 is manufactured in each case a package 18, as shown in Figures 7 and 8.

The plate piece 10 according to Fig. 1 comprises a rectangular laminar cutout, in the present case made of single-wave cardboard. The longitudinal direction of the plate piece 10 is characterized by a double arrow
L.

In the plate piece 10 they are formed, for example by grooving, milling, drilling, biting, notching, ribbed or similar, eight fold lines 20, which run parallel with respect to the longitudinal direction L and that extend along the entire length of the piece of plate 10. These fold lines 20 limit nine sections, the section on each outermost side being designated by 22, the sections connected to them and the sections located in the center by 24 and the two sections, located in each case between these sections 24, through 26. The width of sections 22 plus Exterior is designated by B1. These sections 22 will form more late longitudinal walls 28 of the body part 10. The width of sections 24 is designated by B2. These sections 24 they will later form floor pieces 30 of 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. Each of the adjacent sections 26 in each case will form more take a separation wall 32 from the body part 12. when, as in the present case, the width B3 is chosen larger than the width B1 the separation walls 32, have a greater height than the longitudinal walls 28. These heights can be chosen however discretionally. Just keep one available plate piece 10 of corresponding width and form lines of folded 20 in correspondingly different places.

During the manufacture of the body part 12 shown in Fig. 4, from the plate piece 10, are raised the outermost sections 22, so that they enclose an angle straight with the floor parts 30, arranged in a plane. How I know you can recognize in particular in Fig. 3, sections 26 are raised in each case contiguous and, at the same time, the pieces of floor 30 on top of each other, until the sections 26 that form in each case a separation wall 32 are in contact superficially with each other, as shown in Fig. 4. The walls of separation 32 raised enclose with floor pieces 24 adjoining an angle of 90º. Sections 26 that form a wall of separation 32 are held together, preferably by surface adhesion This connection of sections 26 in each case contiguous can take place however also in another way and general way as by hooked, locked or similar.

The separation walls 32 and the walls lateral 28 give the body piece a resistance extraordinary, so that the floor pieces 30 can be remarkably charged, without them bending so disproportionate

The side piece cutout 16 shown in the Fig. 5 presents an essentially rectangular section which is intended to form a side wall 34. Side wall 34 is limited, on the one hand, - above in Fig. 5 - by the edge 36 of the side piece cutout 16 and, on the other, by a fold line of floor 38 that runs parallel to it. The lateral limitation is indicated by two lateral folding lines 40 that run perpendicularly with respect to the ground folding line 38. The distance of the two lateral folding lines 40 corresponds to width B, shown in Fig. 4, of body part 12. The distance from the floor folding line 38 with respect to the edge 36 located above corresponds to the width B3 - compare Fig. 2 - and, consequently, at the height of the separation walls 32

Along the side fold lines 40 they are connected, to the section that forms the side wall 34, wings sides 42, which essentially have the shape of an L and which are subdivided by a ground folding line lateral 44. The lateral ground folding line 44 runs in straight extension with respect to the ground folding line 38. Along the floor folding line 38 it is connected to the wall side 34 a bottom wing 48, whose width, measured perpendicularly with respect to the ground folding line 38, corresponds to the width of the wings of lateral bottoms 46. The wing bottom 48 and side bottom wings 46 are separated between yes by a cut, which has the shape of a triangle rectangle of equal sides, this triangle being arranged symmetrically with respect to the side wall line 40 long imagined. In the area of the imaginary cut-off point of the side fold lines 40 with the floor fold line 38 and the lateral floor folding lines 44, the part cutout side 16 has an essentially rectangular cut 50. This It is arranged symmetrically with respect to the lateral folding line 40 and extends from the floor folding line 38, a part small, within the corresponding lateral bottom wing 46 and the bottom wing 48 and, a larger part, inside the wall side 34 and side wing 42 assigned. The part, with which the cut 50 extends within the bottom wing 48 and the bottom wing side 46 is slightly larger than the thickness of the piece cutout lateral 16.

The side piece cutout 16 also presents, at the end located above the side fold lines 40, in each case a reinforcement tab 52 protruding in the direction up, which is formed diametrically opposite the cut fifty.

To lift a side piece 14 from a side piece cutout 16 side wings 42 are raised along side fold lines 40, until they enclose, together with the intermediate side wall 34, in each case an angle straight. Also, as Fig. 6 clearly shows, the wing of bottom 38 and side bottom wings 46 are raised in the direction inward, around the ground folding line 38 or the lateral floor folding lines 44, so that they become located in a plane. The 50 cuts are now placed thanks to it in the corner areas of the floor side of the side piece 14. Similarly, reinforcement tabs 52 are located in the corners of the side piece 14 located above.

Packing 18, as shown in Figs. 7 and 8, is manufactured thanks to the fact that in the body part 12, in its opposite ends in the longitudinal direction L, is arranged in each case a side piece 14. At the same time, the pieces of floor 30 of body part 12 comes into contact on the wings bottom 48 and the two outer floor pieces 30 also on the lateral bottom wings 46 as well as the longitudinal walls 28 on the inner side of the side pieces 14 on the wings lateral 42. Bottom wings 48 and lateral bottom wings 46 are fastened in the floor pieces 30 of the body part 12, preferably by surface adhesion. This clamp can take place here in another way and in general known.

As can be deduced from Fig. 8, the sides that extend at right angles to the lines of side folding 40 of the essentially shaped side wings 42 of L, has a height, measured from the folding line of lateral floor 44 to the upper edge, which corresponds essentially at the height of the longitudinal walls 28.

The separation walls 32 may have, as indicated in Fig. 8, protruding tabs 54. For this must be arranged in the plate piece 10 - Fig. 2 -, in the folding lines 20 that limit sections 26 in each case contiguous, C-shaped cuts that pass through the piece of Plate 10, enter one of these sections.

In addition, the bottom wing 48 can, as can be detach from Figs. 5, 6 and 7, it has a tongue 56 that can place.

Figures 9 and 10 show, in view or view side, two 18 packages stacked on top of each other, as they have been described above in relation to Figs. 1-8. At the same time, the reinforcement tabs 52 of the packaging located 18 below they engage in the cuts 50 of the packaging 18 located above. Thanks to this, a displacement of the two becomes impossible. packaging 18 relatively to each other, which leads to a stacking  extremely stable Side pieces 14 of packing 18 located above lean along the edge 36 of the wall side 34 located above, on the side pieces 14 of the packaging located below. If the separation walls 32 are formed the same high than the side walls 34, the floor pieces 30 of the packaging located above are supported in each case also by the separation walls 32 of the packaging 18 located below.

It is understood by itself that through Choice of the length L of the plate piece 10 can be manufactured  18 packages of different lengths. Plate piece 10 can therefore also present a square shape. When the Packaging width does not vary can be used, regardless of length L, side pieces 14 formed same.

Obviously, it is also imaginable to make a Packing 18 without separation walls 32. In this case you have to provide only two fold lines 20 in the plate piece 10, which limit two sections 22 and a section 24 located between they. The outermost section on each side is raised to give a longitudinal wall 28, while section 24 located between them forms the floor piece 30.

It is also possible to provide a single wall of separation 32. In this case it is necessary to provide correspondingly in the plate piece 10 five fold lines 20, which separate six sections, that is, two sections 22 located in the outside, in each case a section 24 connected to them and two sections 26 located between these two. During the elevation you are sections 26 then form the separation wall 32, the sections 24 form pieces of soil 30 and sections 22 form the longitudinal walls 28.

Obviously it is imaginable to foresee, of form and corresponding way, also more than two separation walls 32

It is also possible to dispense with the trimming of side piece 16 of the side bottom wings 46. In this case however, the lateral wings 42 must be attached to the walls Longitudinal 28. Obviously, they can be fixed, in case of there are lateral bottom wings 46, the lateral wings 42 to the longitudinal walls 28.

It is also possible to subdivide the bottom wing 48. In case of bottom wing 48 subdivided or not extended by at least until the side fold lines 40 must be put taking care that every piece of floor 30 is connected, at least by zones, with the bottom wing 48 or a part of it.

The packaging 18 may be provided with a top.

The device, shown in Fig. 11, for the elevation and assembly of packaging 18, as explained above, It presents five seasons. Seen in production direction P comes after a deformation station 58, a station of folded 60 for the manufacture of the body part 12. This one they follow, one after another, a first assembly station 62 and a second mounting station 64, for mounting a first or second side piece 14. As a last station, a delivery station 66, which delivers the finished packaging 18 of manufacture a stacking or removal device.

The deformation station 58 has stops sides 68 that can be adjusted to the width of the pieces of plate 10 to be processed. These center the plate piece 10 supplied by a conveyor 70, for example a belt conveyor If transporting the plate pieces 10 takes place through a vacuum transport installation, the plate pieces 10 are released briefly in the area of the stops lateral 68, in order to orient them.

The lateral stops 68 follow, in the production direction P, the deformation unit 72. This presents in the present case, on a rotating shaft 74 arranged perpendicularly with respect to the direction of P production, grooving, milling or drilling discs 76 arranged in the places of the folding lines 20 to be generate. During the transport of the plate piece 10 through the deformation unit 72 fold lines 20 are generated in The desired places.

Then the continuation of the transport of the plate piece 10, in one piece, equipped with the folding lines 20, to the folding station 60. This presents elevation caps 78, in order to fold the outermost section 22 on each side 90º to give a longitudinal wall 28. The covers of elevation 78 can be moved towards each other, as indicated by means of arrows 80, in order to raise sections 26 to give separation walls 32, thanks to the floor pieces 30 They are moved towards each other. The folding station 60 presents in addition, adhesive application organs 82, which endow in the desired areas sections 26 with adhesives. The station of Folding 60 may also be provided with clamping elements. which squeeze each other, on both sides, from above, the sections 26 forming a separation wall 32, until it has formed the adhesion.

Then the transport of the body part 12, formed in the folding station 60, to the first assembly station 62. This presents an installation 84 to rotate body parts 12 through a vertical axis 12 supplied with its longitudinal direction L that runs in the production direction P. Next to the turn installation 84 a side piece folding device 86 is arranged. A transport facility, indicated by arrow 88, drives in each case a cutout of side piece 16 towards other organs of application of adhesive 82, which apply adhesive on the wing bottom 48 and side bottom wings 46.

The transport facility indicated by arrow 88 carries the side piece cutout 16, provided with adhesive, to a folding device 90. This folds with elements generally known the side piece cutout 16, along side fold lines 40, in each case 90º and place the cutout of side piece 16 such that the side wall 34 is located in a vertical plane, which runs parallel with with respect to the production direction P. In the device folding 90 continues to fold, in a horizontal plane, the wing of bottom 48 and side bottom wings 44 provided with adhesive. He side piece cutout 16 is represented with dashed lines and point and piece 14 finished with continuous lines.

As indicated by another arrow 88 ', the piece side 14 moves over body part 12, until the wall side 34 is in contact with body part 12. A then the side piece 14 is raised, so that the wing of bottom 48 and side bottom wings 46 provided with adhesive come into contact with the floor pieces 30 of the body part 12. Advantageously, pressure organs are provided with the in order to tighten the bottom wing 48 and the bottom wings together sides 46 as well as the floor pieces 30 of the body part 12, until the adhesive connection has been established.

The body part 12 provided with the part side 14 is then supplied to the second station of assembly 64 in the production direction P. This presents another 86 'side piece folding device, specularly formed with respect to the side piece folding device 86. In a manner and exactly the same way as described above, it it raises a second side piece 14 here, it is arranged in the piece of body 12 and adheres with it. The packaging 18 already finished is then transported, in the production direction P, to the delivery station 66.

It is imaginable to anticipate, between the first season of assembly 62 and the second assembly station 64, a station of filled to fill body part 12 provided with only one only side piece 14, with the merchandise to be packed.

It is also possible to arrange both devices folding side piece 86, 86 'opposite each other in the turning installation 84.

They are then arranged in each case simultaneously the two side pieces 14 in a body piece 12.

A single one can also be provided side piece folding device 86. After mounting a of the lateral parts 14 the body part is then rotated 180º 12, by a turning installation 84, after which it is mounted the other side piece 14, by the side folding device 86.

If the pieces do not have to stick together corresponding, the device does not need to present organs of adhesive application 82, 82 '. Present then at the stations corresponding stapling, welding, ultrasound and other units generally known for making connections.

The packaging 18 according to the invention can be easily manufacture completely automatically. In special, 18 different length packages can be manufactured in the same installation, having to be carried out only adjustments that depend on said length.
