"Bottom and/or lid of a stackable goods carrier" 5

The innovation concerns a base and/or lid of a stackable goods carrier,

Such product carriers are known, for example, in the form of closed containers, whereby the containers have both a base and a lid. Furthermore, tray-like product carriers are known, which are referred to as "trays". Such trays are used to hold packaging that has sufficient inherent rigidity, &zgr;. e.g. boxes, tin cans and the like, whereby a second tray

can be placed as a lid over the goods.

In practice, the problem arises that when stacking several such product carriers, real towers of goods are created, whereby slipping or shifting of the

a product carrier in relation to the adjacent product carrier cannot be ruled out. This can cause the product tower to topple over, which can damage the product carriers, the goods themselves and possibly pose a health risk to staff or customers

can.

The innovation is based on the task of creating a floor

and/or lid of a stackable product carrier so that it can be used in the production of a product

tower using several similar goods carriers increases the stability of the goods tower so that the risk of damage to goods or injury to people can be excluded.

This problem underlying the innovation is solved by the design of a base and/or a lid of a stackable goods carrier according to claim 1.

In other words, the innovation proposes profiling surface-like areas, i.e. not just achieving an interlocking based on thin edges running along the edge of the base or cover. Such narrow edges, which can surround the adjacent component like a collar, are on the one hand sensitive to impact and on the other hand, depending on the

forces do not provide sufficient support to reliably prevent the two goods carriers from shifting against each other.

Rather, the innovation proposes to cover large areas

of the lid or the base itself and thereby achieve a stable interlocking between the two adjacent product carriers when stacking a tower of goods as well as a robust design of the lid or base surface itself.

Advantageous embodiments of the innovation can be found in the subclaims.

Examples of the innovation are given below

The drawings explain this in more detail.

Fig. 1 shows a first embodiment in which the

profiled areas are formed by ribs and grooves, '*

Fig. 2 shows a modified embodiment compared to Fig. 1

example, also with ribs and grooves, and Fig. 3 an embodiment in which the profiled

Areas are formed by knobs and pits.

In Fig. 1, two product carriers are designated with 1, which are designed as so-called trays, so that depending on the orientation of the product carrier 1, the product carrier 1 forms an upwardly open tray for receiving objects (drawn in Fig. 1 in the upper half of the illustration) or the

Bowl is open at the bottom (shown in the lower part of Fig. 1) and can be used as a lid.

With the help of such trays, goods can be handled that are in sufficiently stable packaging, for example in cartons, tetra packs, cans or the like. In this case, the lower goods carrier 1 shown in Fig. 1 can be placed on such goods as a lid, while the upper goods carrier 1 shown in Fig. 1 serves as a base for receiving such goods, which are then

Ceiling! in the form of a similar goods carrier 1 can be additionally secured.

For the production of goods towers in which several goods carriers 1 filled with goods are stacked on top of each other,

the product carriers 1 have profiled areas 2 that are formed by ribs 3 and grooves 4. The profiled areas 2 are flat and cover almost the entire base or lid area of the product carrier 1.

The longitudinal direction of the ribs 3 and grooves 4 in different areas 2 run at an angle to each other, so that, when the product carrier 1 shown at the top in Fig. 1 is placed on the product carrier 1 shown below, an interlocking effect between the interlocking profiled areas

areas 2 of the two product carriers 1 and the different direction of the ribs 3 and grooves 4 of the individual areas 2 results in an overall displacement protection of the two product carriers 1 against displacement in any horizontal direction.

In this way, a stable and safe goods tower can be produced with the help of the goods carriers 1 shown.

Fig. 2 shows a representation similar to Fig. 1, whereby the goods carriers 1 are shown as closed containers and

the actual containers are only indicated. Only the bottom or lid area of the containers is particularly highlighted in Fig. 2. Furthermore, in a modification of the embodiment of Fig. 1, a different arrangement of the profiled areas 2 is shown. As in the embodiment

According to Fig. 1, the interlocking effect also occurs here when two similarly designed product carriers 1 are stacked on top of one another, so that the angular course of the ribs 3 and grooves 4 ensures that they cannot be displaced in any horizontal direction.

In Fig. 3, another embodiment of a profiled area 2 is shown, whereby the profiling is achieved by knobs 5 and pits 6. In contrast to the square design shown, the knobs or pits can also be round,

be elongated or otherwise formed. Such a profiled area 2 can, for example, extend over the entire surface of a product carrier or - as indicated in Figs. 1 and 2 - affect delimited areas of the lid or the base of a product carrier 1.

In Fig. 1 and 2, free spaces are provided between the profiled areas 2. Packing tapes can be guided through these free spaces, for example to hold together a packaging unit which consists of a lower and a

upper tray and goods arranged in between.

To achieve a shift lock and an interlocking effect between two product carriers 1, for example,

known from the prior art in that at the bottom of the

Goods carrier 1 has a collar-like peripheral edge which, when stacking this goods carrier on a similar goods carrier, covers the upper lid area of the lower
encompasses the carrying of goods.
5

Compared to such a design, the innovative design of the product carrier 1 with the profiled areas 2 has the advantage that a large contact area of the product carrier 1 on a flat surface is achieved, so that no high surface pressures occur which could lead to

damage to the underside of the goods carrier 1 standing on a floor. In addition, because no narrow protruding areas are created, the entire goods carrier 1 can be easily moved on a roller conveyor, so that the handling

of the goods, which are assembled on a goods carrier 1

is made easier.
