Abstract

The container has two parallel side walls, one (2) of which is widened in the opening direction. This is fastened flush to the base (5). The remaining side wall (3) extends widening towards the container opening, to merge at the top, in a dividing zone (9), towards the exterior. Projecting regions (14,15), on the base, enter recesses (11,12) of a container stacked underneath and rest, when stacked above, on the opening rim of the container underneath. Stacking projections (6), under the base, may enter the opening of a container, when stacked one on the other, supported against the recess edge. All side walls may have taper, for moulding.

Description

The invention relates to a cuboid box, preferably made of plastic, for transport and Storage of goods with side walls, Bottom walls, a gripping and rotating Stacking edge and provided on the bottom Footprint with stacking protrusions if necessary for stacking the same boxes on top of each other and / or in Cross-stacking.

In particular, the invention relates to so-called shelf boxes for packaged goods or soft goods. Such Boxes are also on sale as presentation boxes local for example for cuboid milk cartons or the like is useful. These boxes are preferably trough-like closed forms, so that a leak protection against leaking liquid is formed. Boxes that are so useful and  are usually of a dimension of 400 × 200 mm or also from 300 × 200 mm. You can also a similar division in the ratio of 2: 1 or Own 3: 2. The specified dimensions are around ISO dimensions for compound stacking. Such boxes are suitable for stacking columns as well as for crosses composite stacking. One understands column stacking in this context a stack of Boxes on top of each other, with the stacked ones Boxes in line with the stacked boxes are aligned. Cross-stacking means one such stacking, in particular boxes with an aspect ratio of 2: 1 crosswise are stacked so that on two with the longer sides boxes arranged parallel to each other and next to each other two identical boxes can be stacked offset by 90 ° can.

Such boxes are quite common and many in use. They are usually made of plastic  manufactured. A disadvantage of such boxes is that the Return of empty boxes occupied the same volume becomes, as with filled boxes, which is disadvantageous affects the cost of return transportation.

There are boxes known, which also interlock are nestable, but such boxes either have a hinge formation or the like, so that their footprint can be reduced and they are nestable into each other, but problems arise arise with regard to cleaning, or else it acts so-called rotary stacking containers, which are in a certain orientation are stackable and the one another by rotating through 180 ° relative to each other are nestable. Such boxes are special Support corners and the like for load transfer at Stacking required, so stacking in different positions is not possible. In addition is such boxes require the user to the correct alignment of the boxes when stacked stack, otherwise the boxes are unwanted  are nested into each other and the one inside Goods can be crushed.

Based on the prior art described at the beginning the invention has the object of a box Generic type of creating a stack in column form or in composite stacking in any Alignment of the boxes to each other allows, however also a space-saving nesting of empty ones Boxes should be possible, but in particular dispensed with hinge designs or the like shall be.

To achieve this object, the invention proposes that two mutually parallel side walls and one of the other two side walls from the flush Ground connection starting in one step towards the mouth are offset to the outside of the box, the Step width approximately the wall thickness of the side walls corresponds, or two opposite side walls and at least one of the other two side walls diverging from the flush bottom connection to the mouth  run, with the divergence of each wall compared to the solder on the box bottom about the Wall thickness corresponds to at least that remaining, not stepped side wall or also the this opposite side wall from one to Box interior offset end of the floor (Offset dimension a multiple of the wall thickness) for Aiming box mouth and sloping diverging direction and with stepped Sidewalls at the level of the neighboring level Walls in a step offset of the neighboring Walls corresponding to the outwardly displaced wall part passes over, which runs parallel to the corresponding wall part the opposite stepped side wall runs, that this wall part as well as the corresponding one Wall part of the opposite wall at least has a window-like recess which extends from an area close to the mouth to near the step or extends up to level or at unclassified divergent side walls window-like recesses are provided in the side walls, which differ from an area close to the mouth to one of the boxes  extend deep corresponding area near the ground that on the floor over the flush lower ones Wall parts with recesses in the upper area provided side walls in extension of the floor above areas are formed for the purpose the nested stacking of the same boxes in Column stacking in the recesses of a lower nested box intervene and the purpose of Stacked on top of each other in columns Rest the mouth of a stacked box and finish flush with it in the outer flight.

Different alternative solutions are according to the invention intended. On the one hand, it is possible to have two in parallel Sidewalls, preferably the longer ones Side walls, starting from the flush floor connection towards the mouth in one step towards the outside of the box trained offset, so that there is between the Cavity enclosed in the walls is stepped towards the mouth widened, the step width about the Wall thickness of the side walls corresponds. One of the two other side walls, preferably the  narrower side walls can also be stepped formed from the flush bottom connection expand towards the mouth towards the outside of the box so that the box interior is enlarged. Here too the step width then corresponds to the wall thickness of the Side wall. In this embodiment, the further side wall, preferably the further narrow Side wall that is not stepped from one to the Inside the box offset end of the floor (offset a multiple of the wall thickness) to the box mouth Aiming diagonally and diverging The interior of the box extends in a directed manner. It can but also the one opposite this wall Side wall can be formed in the same way. Instead of the step-by-step training is also possible in the two opposite side walls diverging from the flush bottom connection to the mouth run, with the divergence of each wall compared to the solder on the box bottom about the Wall thickness corresponds. Then the two can other side walls either both from one to the Inside the box offset end of the floor (offset  a multiple of the wall thickness) to the box mouth aimed obliquely and diverging or else only one of the two side walls has the strong one Divergence angle due to the offset of a multiple the wall thickness and the other side wall only one divergence that the divergence of the other two opposite side walls corresponds. At all these training courses are then in the corresponding Wall parts provided window-like recesses, in which the extensions of the bottom protrude in the form Areas can be used provided the boxes are in Box stacking should be put together.

According to this training, it is possible to make appropriate Boxes arranged in the same direction or in 180 ° Column-like arrangement rotated around the vertical axis stack on top of each other, taking the stacked boxes each with the area protruding above the floor on two parallel edges on the one below located box, especially its rim, can support. It is also a composite stack such boxes possible.  

For space-saving empty nesting of such boxes these are nested into each other, for which an empty one Box as bottom box a box to be nested same type can be supplied so that this box to be nested initially in an inclined position into the mouth of the box below is introduced, the inclined wall area den Provides free space so that the one to be nested Box with its on the inclined surface Projection into the corresponding window or Recess of the box located below and slightly shifted to the side can be, so that on the parallel edge protrusion formation on the ground also in the box under the box to be nested Box can be inserted until this projection too the corresponding recess (window-like opening) reached. Then the box is nested inevitably through the inclined surface in a target position transferred, in which it is aligned in the lower stack is nested. The nesting depth is in particular on the corresponding height of the recesses  dependent, this height according to the desired Nesting degree can be selected. Limiting for the degree of nesting is also the order of the step offset, since the box is nested the top box with the bottom surface of the step on the Edge of the box underneath sits on. Depending on the distance of the step formation from the edge of the mouth The box can vary depending on the height of the window the degree of nesting can be determined.

The window-like recesses as well as the corresponding protruding areas of the box bottom, which can be inserted into these recesses different shape, height and arrangement as well as number exhibit. For example, it is possible to have three in parallel Recesses in the respective side walls to train, then three above Provide areas as an extension of the floor area are. But it is also possible to have a single window to be provided in one wall and then the corresponding extension of the floor (previous Area) to match the width of the window, whereby  again the above areas by a single Area or by several finger-like areas can be formed parallel to each other and are arranged and formed side by side.

A preferred further development is seen in the fact that stacking projections are formed below the bottom, those of boxes stacked on top of one another in columns reach into the mouth of the stacked box and with nested boxes on the bottom edge of the respective recess itself support.

Furthermore, it is preferably provided that on the oblique Wall part possibly near the transition to the offset A centering projection is formed on the outside of the wall part is in the nesting position on the inside of the top Part of the wall of the box nested in the same direction is present.

In particular, it is preferably provided that all sides walls have at least one taper.  

Especially when molding from plastic is one such taper. So far the term "parallel" in claim 1 in the broader sense also to understand that the corresponding Sidewalls not exactly parallel to each other are aligned, but slightly from the floor to Mouth diverge, resulting in the taper corresponds. There is also a larger conicity Circumstances useful and necessary to have an appropriate To enable nestability (nesting).

An embodiment of the invention is in the drawing shown and described in more detail below.

It shows:

Fig. 1 schematically shows a box according to the invention in principle in longitudinal section with two similar boxes stacked in composite stacking;

FIG. 2 shows the system of a composite stacking in plan view;

Fig. 3 two stacked boxes in side view, partially cut;

Fig. 4 likewise in front view;

Fig 5 seen two boxes in box position shown in Fig. 3.

Fig. 6, the box position in the view according to Fig. 4;

FIGS. 7 and 8, an alternative embodiment in the view of FIG. 3 or FIG. 5.

The embodiments are cuboid boxes made of plastic, which are suitable for transporting and storing goods. The boxes have side walls 1 , 2 , 3 , 4 . Furthermore, they have a bottom 5 and a gripping and stacking edge running around the mouth. At the bottom of the bottom 5 stack projections 6 , 27 are formed. These boxes are both the column stacking, so for stacking the same boxes according to FIG. 3 and 4 and Fig. 7 suitable, as well as for cross bond stacking shown in FIG. 1 and 2. According to the invention, these boxes nestable in the empty state, as in the embodiments shown in FIG. 5 and 6 or Fig. 8.

In order to make this possible, the boxes according to FIGS. 1 to 6 have the two mutually parallel side walls 1 , 4 (these are the longer side walls of the box which is rectangular in cross section) and the one side wall 2 , which is narrower than the side walls 1 , 4 is formed, starting from the flush bottom connection (in the drawing figures below) towards the mouth, an extension in the form of a step 7 , the step width corresponding to the wall thickness of the side walls. The side wall 3, which is not equally stepped, runs obliquely diverging from an end of the base which is offset relative to the interior of the box (to the right in the drawing figures 3 and 5 ) towards the mouth, the back offset of the base 5 or the connection point of the side wall 3 to the base 5 being a multiple of the wall thickness , in the exemplary embodiment is approximately four times the wall thickness. At the level of step 7 of the adjacent walls, this inclined wall part 8 merges into a wall part 9 which is offset outwards in accordance with the step offset of the adjacent walls 1 , 4 and which runs parallel to the corresponding wall part of the opposite stepped side wall 2 .

The term parallel in this context not to understand the exact parallelism, but to understand it can also have a slightly conical or wedge-shaped design be realized, at least the taper in the manufacture of such boxes made of plastic corresponds.

The wall part 9 , like the corresponding wall part 10 of the opposite wall 2, has a window-like recess 11 or 12 . The recess 11 or 12 extends from an area near the mouth to the vicinity of step 7 , in the exemplary embodiment even up to step 7 .

The base 5 has, over the flush-fitting lower wall parts 8 and 13 of the side walls 2 , 3 provided with the recesses 11 and 12 in the upper region, in the extension of the base 5, projecting regions 14 , 15 , which for the purpose of nested stacking according to FIG . 5 and 6, the same boxes in column stacking in the recesses 11, 12 engage a untergeschachtelten box and for the purpose of succession stacking shown in FIG. 3 and 4 lie in column stacking on the mouth edge of an under stacked box and flush with those in the outer flight, such as It can be seen in particular from Fig. 3. In order to be able to transfer a stacked box from the position according to FIG. 3 into the position according to FIG. 5, it is necessary to lift the upper box slightly from the mouth edge of the lower box and to turn it about a central axis, which is at 16 in FIG. 3 is specified. The rotation takes place for example by 30 ° or 45 ° clockwise, so that the upper box with the projection 15 dips into the lower box and this projection reaches the area of the window 11 .

Then the upper box can be moved by the amount of the offset back of the sloping side wall 8 in the drawing to the right, so that the left projection 15 can also dive into the lower box and can be moved into the recess 12 . The upper box can then be transferred into the position according to FIG. 5, with a forced alignment and displacement in the transverse direction taking place through the oblique wall 8 , which comes to bear on the inner wall area of the surface 9 of the side wall 2 . The nesting position according to FIG. 5 is then reached.

The below the bottom 5 provided for stacking projections 6 engage in in column stacking stacked boxes according to FIG. 3 in the mouth of the under stacked box and at nested boxes according to FIG. 5, they rely on the near-surface peripheral edge of the respective recess 11 and 12 respectively from .

In addition, the mouth of the lower box is supported according to the box position according to FIG. 5 on the lower step surface of step 7 , as can be seen from FIGS. 5 and 6.

This determines the box depth. A corresponding degree of nesting or a smaller degree of nesting can be achieved by appropriate laying of step 7 and enlarging or reducing the recess 11 or 12 .

On the inclined wall part 8 , a centering projection 17 is formed on the outside near the transition (at 7 ) to the offset wall part 9 , which in the box position according to FIG. 5 rests on the inside of the upper wall part 9 of the box nested in the same direction.

In the illustration of FIG. 5, an additional advantageous embodiment is shown. There, the bottom 5 is formed at least on the inside in a scale-like manner, so that correspondingly inclined contact surfaces 18 are formed, which are separated from one another by step-like shoulders 19 . The step-like shoulders 19 run parallel to the track side wall 8 , while the contact surfaces 18 enclose right angles with the inclined surface 8 or with parallels running thereto.

In this way, the presentation of cuboid parcels 20 is improved, since the parcels, as shown only schematically in FIG. 5, are arranged obliquely, so that their foremost end face 21 is clearly visible to a viewer and he can see the goods accommodated in the box can clearly identify.

In Figs. 7 and 8 using the same reference numerals, an alternative embodiment is shown. In this embodiment, two opposite side walls 1 and 4 are provided, which diverge from the lower flush bottom connection to the mouth, so that the interior of the box becomes larger towards the mouth. This divergence corresponds to the wall thickness in the area of the connection point compared to the vertical on the box floor. The side wall 2 is also formed in a divergent manner from the bottom to the mouth, the degree of divergence here also roughly corresponding to the wall thickness of the walls. Alternatively, this wall could also be designed as the side wall 3 , which will be described in more detail below.

The side wall 3 is directed from an end of the base 5 which is offset towards the inside of the box (the offset corresponds to a multiple of the wall thickness) and is directed obliquely towards the box opening and diverging. The side walls 2 and 3 have corresponding window-like recesses 11 , 12 , which extend from an area near the mouth to such a distance area from the floor 5 that corresponds to the desired nesting depth. At the bottom 5 are flush subsequent and lower wall parts of the side walls 2 and 3 in the extension of the bottom 5, projecting portions 14, 15 are formed, the same for the purpose of nested stacking boxes in column stacking in the recesses 11, 12 of a untergeschachtelten box are used and can intervene there, as shown in Fig. 8, or which can be placed in stacked columns for the purpose of stacking on the mouth edge of a stacked box and close flush with it in the outer alignment, as shown in Fig. 7. The insertion of the respective upper box into the lower box is carried out analogously, as described in the previous embodiment.

Depending on the degree of divergence of the side walls and the size of the window-like recesses nesting of different depths possible.

The invention is not based on the embodiment limited, but often within the scope of the disclosure variable.

All new, in the description and / or drawing disclosed individual and combination features are considered viewed essential to the invention.
