Lattice box

The invention relates to a grid or slatted box, for example for bottles, made of plastic with a rectangular bottom, two vertical long side walls and two vertical transverse side walls.

The well-known lattice boxes of this type usually have at the top and bottom of the straight long side walls on their whole

zen length reinforced edges, and the corners of the boxes are reinforced by vertical edges at the ends of the walls. The remaining part of the straight longitudinal side walls is formed by a flat plate. To the stability of the To enlarge the longitudinal side walls, are in the known boxes on the inside and / or outside of the flat Plates provided with vertical and possibly horizontal ribs. However, the known boxes require a relatively large amount of plastic material in order to obtain sufficiently resistant longitudinal sidewalls. There are especially the long side walls, dLe due to their considerable Length must be reinforced because the boxes are stacked alternately and the long side walls must bear the edges of the box floor above between their ends. This problem arises for the flat transverse side widths in which in openings that are generally used as handles are provided, in a lesser way.

In order to be able to reduce the number and / or size of the ribs, were already in the flat sections of the longitudinal side walls inwardly protruding, vertical grooves made. This makes the mold for injection molding the Boxes more complicated, however. In addition, the distance must

409814/0429

be relatively large between the grooves, so as to-not to increase the need for plastic compound too much, so that the reinforcement of the longitudinal side walls suffers.

The object of the invention is therefore to avoid these disadvantages and to create a lattice box made of plastic, which has a relatively high rigidity with a relatively small amount of plastic and its Manufacture is quick and easy.

To solve this problem, at least the two longitudinal side walls have a kinked zone in which the individual kink edges in the longitudinal direction of the walls are directed alternately to the inside and outside of the box and which extends at least over part of the length and part of the height of the wall of the lattice box.

This longitudinally to and fro zone does not offer a maximum of strength with a minimum of mass only in the height direction but also in the lateral direction.

In a particular embodiment of the invention, the kinked zone is zigzag and is exposed Parts together that are directed at right angles to the ground and connected to each other at an obtuse angle.

Preferably, the parts are bent in a zigzag shape Zone equal to each other.

In another embodiment of the invention, each Part of the kinked zone is a full plate.

In an advantageous embodiment of the invention, have the longitudinal walls outward at their longitudinal ends protruding edges and the kinked zone extends the entire length between the bands.

In a further embodiment of the invention have the longitudinal walls at the top have an outwardly projecting edge and the kinked zone extends over the whole Height between the edge and the floor.

In a further embodiment of the invention, the base has a downwardly ¹ protruding staple collar which extends at least over part of the length of the longitudinal side walls, while the knee edges of the bent zone, which extend inward, begin above the stacking collar.

4098U / Q429

In the embodiment mentioned, all are vertical Forces that are effective on the longitudinal side walls, taken up in a suitable manner by the stacking collar and follow Lich transferred to the support surface of the lattice box.

The invention is shown by way of example in the drawings. It shows:

The lattice box shown in the drawings is made of plastic and has an approximately rectangular bottom 1, two longitudinal side walls 2 arranged vertically on this and two transverse side walls arranged perpendicular to these 3.

The bottom 1, which is designed as a grid, consists of * a right-angled frame ^, the corners of which are provided with a convex curve towards the inside, of rings 5 arranged in longitudinal and transverse rows inside the frame 1 \ and of connecting pieces 6, which connect the rings 5 with each other and with the frame l \ . Part of the grating has a height which is noticeably greater than the rest of the grating and which protrudes downward over the lower edge of the longitudinal side walls 2 and the transverse side walls 3. The rest of the grille does not protrude beyond the lower end of the side walls 2 and 3. The part of the grille with a greater height forms open or closed figures which are hatched in Fig. 5 and identified by the reference number 7. These figures form stacking collar, by means of which the grid box can be afgesetzt on the floor or another mesh box. a portion of the 'frame l \ is formed by sections of different figures 7.

40981 A / 0429

The bottom 1 thus has one over its entire circumference Stacking collar, which is divided into irregular sections.

Each longitudinal side wall 2 has an edge at the top, which consists of a rib 8 and a flange 9. The rib 8 runs parallel to the base 1, which extends over the entire length of the side wall 2. The rib 8 extends to a small distance from the uppermost edge of the side wall 2, against which it is supported. The rib 8 is directed perpendicular to the flange 9, which extends between the rib 8 and the uppermost edge of the side wall 2. The flange 9 is flat. As can be seen from FIG. 1f, the extension of the flange to the floor 1 runs exactly next to the frame k of the floor 1.

Each lay side wall 2 is longitudinally at both ends provided with a groove 10 which protrudes outward. The channel 10 is with its opening to the interior directed. The two channels 10, which extend the furthest to the outside, are over their entire height with the side wall Connected via a connecting piece 11, which is inclined both in the longitudinal and in the transverse direction to the lattice box runs and the longitudinal side wall 2 connects to the transverse side wall.

4Q98U / Q429

The largest part of each side wall 2 is formed by a zigzag-shaped kinked zone 12, the parts of which are perpendicular to the floor 1 and form an obtuse angle with one another. This kinked zone extends from the upper edge 8, 9 to the bottom 1 and between the two channels 10 which form outwardly projecting edges. From a channel 10, the parts of the kinked zone 12 run alternately inwards and outwards of the box. All parts of the kinked zone 12 are identical to one another. The angle between two adjacent parts of the kinked zone 12 is such that measured in the transverse direction of the box, the distance between the outer and inner edges of a part of the kinked zone corresponds approximately to the wall thickness of the parts. The kinked zone adjoins the edge 8, 9 and the bottom 1 in such a way that the outer edges between adjacent parts of the kinked zone 12 extend upwards just below the edge 8, 9, while the two adjacent parts below inside edges of the kinked zone just above the frame k of the floor. In this way, all forces which are directed perpendicularly to the floor and which act on the longitudinal side walls 2 are applied to the frame if of the floor 1 and consequently the same.

dimensions transferred to the interrupted stacking collar formed by the sections of the frame 4, the make up part of the aforementioned Figures 7. At the foot of each longitudinal side wall 2 is along the entire length an edge 13 is provided which is directed obliquely downwards and outwards, and a flange 14 which is perpendicular is directed towards the ground and which is connected to the edge 13 in the longitudinal direction. The lower edge of the flange 14 " has more or less the HcIb of the lower edge of the section of the frame 4 »which does not appear in FIG. 7 and consequently does not belong to the stacking collar. the the two grooves 10 of the longitudinal side wall are connected at the bottom with the edge 13 »14. The outer side of the bottom of the Groove 10 is arranged in the extension of the outer side of the flange 14. The edge 13 is with the outer Section of the kinked zone 12 connected to a small distance from the floor 1. The edge 13 »14 is still connected to the longitudinal side wall via small webs 24.

On the outer side of the flange 14 and the upper and lower sides of the two grooves 10 are small, parallel Ribs'15 running to the bottom! In the middle there are 10 small ribs on the outer side of each gutter

provided that are perpendicular to the ground. The small ribs 15 and 16 prevent mutual sliding the grid boxes when they are stacked next to each other.

On the inside of the longitudinal side walls 2 and at the point where the kinks of the kinked zone 12 go outwards, a small rib 17 is provided, which extends over the entire height of the zone 12 from the frame 1 \ of the floor 1 upwards and extends up to the inside of the flange 9. In the middle of each longitudinal side wall 2, a thicker rib 18 is provided at the point where the kink of the kinked zone 12 goes inwards, which extends equally over the entire length of the zone 12 from the frame k of the floor 1 to over the entire height of the Flange 9 extends »

Each transverse side wall 3 likewise has an edge 8, 9 at the top which is the same as that of the longitudinal side walls and that at its ends with the edges 8, 9 of the two longitudinal side walls connected is. Each transverse sidewall 3 also has two to the bottom 1 perpendicular grooves 10, the bottom of which is directed outwards and the protruding edges with respect to the transverse side walls 3 form. As mentioned above,

A098U / 0429

is the channel 10 at each end of the transverse side wall 3 connected to a longitudinal side wall 2 by means of an orifice wall Π.

Between the edge 8, 9 and the bottom 1, as between the two channels 10, each transverse side wall has a flat zone 19. The flat zone 19 is arranged in the extension of the flange 9 and ends with its lower edge just next to the frame l + _f with which the flat zone 19 is connected.

On the outside of the flat zone 19, an edge 13 » Ik is provided at the bottom, which extends over the entire length of the transverse side wall 3 and which has the same function as the edge 13s 14 of the longitudinal side walls, to which it is connected at both ends Transverse side walls 3 are provided equally on the rims 10 and the flange 14 of the rim 13, small ribs 15 and 16. The flat zone 19 is provided with a rectangular opening 20 which forms a handle. The opening 20 is framed by ribs 21 on the outside of the flat zone 19. The rib 21 extends at the top of the opening over the length of the transverse side wall 3 between the two channels 10, while the vertical ribs 21 extend over the entire height of the wall 3 between the upper edge 8, 9 and the lower edge 13, 1 * f extend.

The lattice box is divided into compartments by partitions 22. The partition walls 22 are perpendicular to the floor 1 and extend Ms approximately halfway up the walls 2 and 3. The partition walls run in the transverse and longitudinal directions or along the rows in which the rings 5 of the floor 1 are located. The partition walls 22 are attached to the bottom 1 with their ends on the two longitudinal side walls or the two transverse side walls 3j which they face. The partition walls 22 attached to the longitudinal side walls are arranged thereon at the level of the inwardly extending edge of the kinked zone 12. On the underside, the partition walls 22 are provided with openings ZJ) in order to save material.

The lattice box described above is particularly stable and requires a minimum of material. Since the longitudinal side walls 2 mainly consist of a kinked zone 12, the longitudinal side walls are particularly stiff, in particular in the direction perpendicular to the floor 1, while the vertical forces are transmitted particularly well to the frame 1+ of the floor 1. The appearance of the lattice box, on the other hand, is very nice.
