Description

The present invention relates to a box, in particular for the storage and / or transport of crockery, with side walls and at least one bottom wall, wherein the side walls and the bottom wall together define a receiving cavity of the box.

Crates of this type are known in a variety of embodiments. They may be used for storage and / or transport of various objects, in particular dishes such as e.g. Plates, cups, bowls, cutlery and the like can be used. The side walls and the bottom wall together surround a usually unilaterally open receiving cavity into which the objects, so in particular the dishes can be introduced.

Many such boxes are formed with a flat bottom wall. By a correspondingly high load on the bottom wall and / or a correspondingly long-term use of the box, it frequently happens in the prior art that the bottom wall as a whole is thrown downwards, ie away from the receiving cavity. If this happens, the bottom wall is no longer completely flat but only in its furthest bulged area on the ground, so that the bottom wall is particularly strongly abraded at these points, which can lead to inability to use and in particular to holes and cracks in the bottom wall. In order to prevent this, it is known to support the bottom wall by means of webs which are preferably formed on it. These webs are often arranged in the prior art lattice-like or honeycomb on the receiving cavity opposite side of the bottom wall. The disadvantage of these webs is, in particular when using a box for storage and / or transport of crockery, that the box on the one hand heavier by the webs and on the other hand water when washing the box in between the webs and the Bottom wall formed corners and edges stuck, so that the box after the washing process takes a relatively long time to dry. This is particularly unfavorable when the box is used for storage and / or transport of crockery.

The object of the invention is to improve a box of the type mentioned above so that on the one hand has a relatively stable bottom wall, on the other hand, the bottom wall but can also dry relatively quickly.

To solve this problem, the invention proposes that the bottom wall is formed with a plurality of spaced-apart and directed away from the receiving cavity bulges.

It is thus a basic idea of the invention, instead of the webs arranged on the bottom wall in the prior art, to form the bottom wall itself with bulges which, owing to their three-dimensional structure, impart high stability to the bottom wall. It is created by the bulges an uneven bottom wall. In the formation of the bulges can be dispensed with essentially on the formation of corners and edges, so that prevents water after a washing process of the box in the long term can accumulate in corners and edges in the bottom wall. As a result, the bottom wall dries according to the invention also faster than the known in the prior art, above, bottom walls. The bulges, which could also be called protuberances or bulges, are thus formed according to the invention directly in the bottom wall. These are therefore not structures such as the known in the prior art webs, which are additionally formed on the bottom wall or arranged on this in a different way. At least some of the bulges preferably also form the footprints or Aufstandspunkte with which the box is placed in the normal operating position on a substrate. On the opposite side they limit the receiving cavity of the box. The box preferably has exactly one bottom wall.

Inventive boxes could also be referred to as boxes. On the opposite side of the bottom wall, the boxes usually have an opening. This is usually surrounded by an edge of the side walls. Through the opening objects can be introduced into the receiving cavity of the box and / or removed from this. Cases according to the invention are not exclusively, but preferably, intended for storage and / or transport of crockery. The dishes may in particular be plates, cups, bowls, cutlery and the like.

The bottom wall could also simply be called a floor. It is a wall of the box, which forms the bottom of the boxes, so limited in the normal operating position of the box, the receiving cavity down. Not necessarily but preferably the bottom wall is completely closed in itself. The bottom wall may be elastic. In this case, it is particularly advantageously biased inwards, ie in the direction of the receiving cavity. The side walls limit the receiving cavity of the box in the normal operating position to the sides. The side walls and the bottom wall are preferably formed as a common one-piece body. Preferably, these are one-piece injection-molded body. The box or in particular the side walls and the bottom wall are particularly preferably formed from plastic. These may be various thermoplastics known per se, such as e.g. Polypropylene, polyethylene and the like act.

Preferred variants of boxes according to the invention provide that the bottom wall has even areas between the bulges. Here, however, is conveniently provided that transitions between the flat areas and the bulges of the bottom wall are rounded. This applies to avoid corners and edges in the bottom wall, preferably for all transitions between the flat areas and the bulges of the bottom wall. In particular, this is seen in a section parallel to one of the side walls.

The bulges are, conveniently completely, curved. A complete curvature is the case when the bulges in each case have no flat or straight sections. For example, the bulges may have the shape of the surface of a spherical segment. The wall thickness of the bottom wall is constant or substantially constant in preferred embodiments of the invention over the entire course of the bottom wall. Since it can come to slight thinning of the wall thickness of the bottom wall in these areas by the formation of the bulges in the bottom wall, preferred embodiments of the invention provide that the wall thickness of the bottom wall in the bulges a maximum of 10%, preferably a maximum of 5%, of the wall thickness the bottom wall deviates in the flat areas.

Preferably, it is also provided that, preferably all, transitions between the bulges and the flat areas of the bottom wall, seen in a plan view of the bottom wall, preferably completely, have a rounded, preferably circular, shape. In addition to the circular shape of the bulges and thus the transitions, as seen in said plan view, other rounded shapes such as ovals and the like can be provided.

Seen in a plan view of the bottom wall, preferred variants of the invention provide that the bulges each have a cross-sectional width and / or cross-sectional length of 1 cm (centimeters) to 8 cm, preferably from 2 cm to 5 cm. The cross-sectional length is measured parallel to the longitudinal direction of the box, the cross-sectional width parallel to the transverse direction of the box. Here, the longitudinal direction of the box is the dimension of the box in which the box is the longest. The transverse direction or the direction of the width of the box is measured orthogonally thereto. The third dimension is the depth or height or the depth direction or height direction of the box. It is measured from the upper end or edge of the side walls to the bottom wall.

In the sense of the above-mentioned bias of the bottom wall can be provided that at least in the unloaded state of the box in a Edge region of the bottom wall arranged bulges continue to extend away in the direction of the receiving cavity than arranged in a central region of the bottom wall bulges. This can be seen from the fact that in a non-loaded, parked on a flat surface box only arranged in the edge region of the bottom wall bulges in contact with the flat surface, while the arranged in the central region of the bottom wall bulges in the unloaded state of the box from the plane Underground lifted or spaced in other words or are distanced. By this measure, if you have loaded such boxes and it turns off when loaded hard on a substrate, a certain damping effect to protect the objects arranged in the receiving cavity, and in particular arranged in the receiving cavity dishes, can be achieved because then the bottom wall in the central Area elastically yield to absorb the shock when setting up the box on the ground.

In particular, when the box is provided for storage and / or transport of plates, preferred variants of the box provide that, in addition to the bulges, at least one elongate channel open towards the receiving cavity is formed in the bottom wall. From this elongated channel can be better kept in position in the box on its edge parked plates. The channel preferably runs centrally in the longitudinal and / or transverse direction of the box. The channel is conveniently formed as a kind of bulge or protuberance in the bottom wall. Also, the transitions between the channel and the flat areas of the bottom wall are conveniently rounded. In addition, the wall thickness in the area of the channel, as stated above with respect to the bulges, is substantially the same as in the flat areas. In this sense, the above with respect to the bulges said analogous to the wall thickness and the rounding also for the channel. It is preferably provided that the bulges and / or the optionally existing channel, seen from the receiving cavity, respectively form depressions in the bottom wall. So you can see in these preferred variants, if one looks from above into the receiving cavity of the box, that the bottom wall is not flat but just formed with corresponding recesses. The maximum depth of the recesses is favorably each greater than the wall thickness of the soil.

The above-mentioned rounded transitions favorably have a radius of curvature of at least 2 mm (millimeters), preferably of at least 8 mm.

In the first embodiment of a box according to the invention shows Fig. 1 a side view on the long side of the box, Fig. 2 a side view of the broad side or transverse side of the box, Fig. 3 a bottom view of the bottom wall 4 of the box, Fig. 4 a perspective view obliquely from above and Fig. 5 a perspective view obliquely from below. The side walls 3 and the bottom wall 4 jointly encase the receiving cavity 5 of the box 1. In preferred embodiments, as shown here, the side walls 3 and the bottom wall 4 of a box 1 each form a common one-piece body. It can For example, be injection molded body. Preferably, the side walls 3 and the bottom wall 4 made of plastic, in particular of a thermoplastic of the type mentioned above. The receiving cavity 5 is accessible through the opening 18 surrounded by the upper edge 19 of the side walls 3. The opening 18 may be replaced by an example in FIG Fig. 6 shown lid 20 are closed. The lid 20 can be fastened in all known ways and manners at the upper edge 19 of the box 1. According to the invention, a plurality of bulges 7 are formed in the bottom wall 4. These are aligned in the direction 6 away from the receiving cavity 5. This means that the area of the maximum bulge 7 of a respective bulge 7 points away from the receiving cavity 5 in the direction 6, ie in the direction 6, the furthest protrudes from the planar regions 8 of the bottom wall 4 surrounding the respective bulge 7. In the plan view from below according to Fig. 5 is particularly well recognized that in the embodiment shown here, the transitions 9 between the respective bulges 7 and the surrounding flat areas 8 of the bottom wall 4 rounded, here are circular. As already stated above, these transitions 9 are advantageously also rounded in a section parallel to one of the side walls 3, so that no corners and edges are formed in the bottom wall 4 as a whole. The cross-sectional width 11 and the cross-sectional length 12 of a respective bulge 7 are favorably in the above range. The cross-sectional widths 11 and the cross-sectional lengths 12 can certainly also have the same values as in the variant shown here with that in the plan view according to FIG Fig. 3 circular shape of the transitions 9 is also the case. The cross-sectional length 12 is measured in the longitudinal direction 15 of the box 1 and the cross-sectional width 11 in the transverse direction 16 of the box 1.

In the FIGS. 3 and 5 It is good to see that in the bottom wall 4 of the first exemplary embodiment of a box 1 according to the invention, in addition to the bulges 7, there is also an elongate channel 17 which is open towards the receiving cavity 5. In the first embodiment, this runs centrally in the transverse direction 16 in the bottom wall 4 of the box 1. Also within this channel 17 and in the region of its transition to the flat areas 8 of the bottom wall 4 are Conveniently everywhere appropriate curves present, so it is not here to form corners and edges in which water can be held long term, comes.

The second embodiment according to the FIGS. 7 and 8 illustrated as well as the third embodiment according to the FIGS. 9 and 10 in that boxes 1 according to the invention can of course have different widths, heights and lengths and can otherwise also be configured differently. For example, in the second embodiment, as in FIG Fig. 8 can be seen, in the bottom wall 4 a longitudinally extending 15 longitudinally extending channel 17, while in the third embodiment according to the FIGS. 9 and 10 was completely dispensed with this channel 17.

Fig. 11 shows a section through a box 1 according to the second embodiment ( FIGS. 7 and 8 ), wherein the opening 18 of the box 1 is covered by a lid 20 and is in the box 2 dishes in the form of a plate. In Fig. 11 It is good to see that by forming the channel 17 in the bottom wall 4 a way to support a standing with the edge on the bottom wall 4 plate 2 is created, so that plate 2, standing on its plate edge, in a simple manner in one such box 1 can be stored.

In Fig. 11 is also good to see that the bulges 7 and also the possibly existing channel 17, seen from the receiving cavity 5, respectively recesses 21 in the bottom wall 4 form. Due to the bulges 7 and the possibly existing channel 17, the bottom wall 4 thus gets a corrugated structure.

This is also good in the cut according to Fig. 12 to see through such a box 1. Good to see here are the rounded transitions 9 between the bulges 7 and the channel 17 and the respective surrounding flat areas 8 of the bottom wall. 4

Fig. 13 shows the section A from Fig. 12 when the box 1 is placed in the unloaded state with its bottom wall 4 on a flat surface 22. At the in Fig. 13 and therefore also in Fig. 12 illustrated variant is provided here that at least in the unloaded state of the box 1, arranged in an edge region 13 of the bottom wall 4 bulges 7 further away in the direction 6 from the receiving cavity 5 as the arranged in a central region 14 of the bottom wall 4 bulges 7. Der As a result, the bulges 7 arranged in the central region 14 and also the channel 17 arranged there if appropriate are arranged at a distance 23 above the planar background 22, while the bulges 7 arranged in the edge region 13 lie directly on the ground 22. By this kind of bias, the above-mentioned damping effect can be achieved when a fully loaded box is placed accordingly ungroundly on the ground, then enters a certain deformation of the bottom wall 4, before even in the central area 4 there existing bulges 7 and Channel 17 come into contact with the substrate 22. As a result, a certain damping effect can be achieved.

In Fig. 13 is also good to see that the wall thickness 10 over the entire bottom wall 4 and thus both in the area of the bulges 7 and the channel 17 as well as in the flat areas 8 is substantially constant or equal. A substantially constant wall thickness is given when the wall thickness 10 of the bottom wall 4 in the bulges 7 and optionally also in the region of the channel 17 deviates from the wall thickness 10 of the bottom wall 4 in the flat regions 8 by a maximum of 10%, preferably a maximum of 5% ,
