The present invention relates to a stackable flat container with a flat and square bottom, four provided Side walls and one upper and one lower each protruding outward from the upper and lower edge of the side walls Circumferential flange.

The container according to the invention is characterized in that that in the upper flange at two diagonally opposite corners of the container each one of this flange after above protruding pin is arranged, while on the two other container corners in the upper flange, as well as below the said pins are provided in the lower flange for receiving such pins formed recesses, and that in the area of the container tokens on the underside of the floor each a pair of ribs, consisting of two parallel to the associated ones Sidewalls at equal distances from the corresponding bottom edge extending ribs, is arranged, the edge distance adjacent pairs of ribs is different.

The following is an embodiment of the subject invention described with reference to the accompanying drawing. It shows:

Fig. 1 is a perspective view of a flat container, Fig. 2 is a side view, partially in section along the

Line II-II in Fig. 1 of the container, Fig. 3 is a view of the underside of the container of Fig. 1,

Fig. 4 shows a vertical section of a container corner along the line IV-IV in Fig. 1 and

FIG. 5 shows a vertical section of another container corner along the line V-V in FIG. 1.

In the drawing, a flat container with a rectangular bottom is shown, which in particular for receiving Food such as fish, patisserie, etc. The container shown has a flat bottom 1 and vertical side walls 2.3. At the top and bottom

W of the side walls each arranged an outwardly projecting, horizontal peripheral flange 4.5, the width of the top flange 4 and bottom flange 5 is the same size. The lower flange 5 is practically an extension of the container base 1 beyond the side walls 2, 3, while the upper flange 4 lies in a plane parallel to the base plane. At the container corners, the respective converging side walls 2, 3 are connected to one another by a corner wall 6 standing at 45 on both side walls, whereby the flange widths at the container corners are increased. On the outside of each corner wall 6 is a between the upper and

. lower flange 4 or 5 extending YerStärkungsrippe 7 arranged. '

At two diagonally opposite corners of the container there is a pin protruding upwards from the upper flange 4 8 arranged, while on the other two container corners in the upper flange 4 and below the pin 8 in the lower flange 5 each a cup-shaped recess 9 or 10 is provided. The recesses 9 and 10 are designed to help when stacking to pick up the pins 8 of the other containers of several containers (see Fig. 4).

On the underside of the container bottom 1, a pair of ribs is arranged in the region of the container corners. As As can be seen from Fig. 3, each pair of ribs consists of two parallel to the associated side walls at equal intervals ribs 11a, lib J, running from the corresponding bottom edge 12a, 12b; 13a, 13b and 14a, 14b, the ends of the ribs of each rib pair converging at the respective container corners each by a connecting rib lic, 12c, 13c and 14c running parallel to the corresponding corner wall 6 with one another are connected. The free ends of the ribs have an inwardly angled section. The length of the ribs is slightly smaller than half the length of the associated container side, so that between the opposing free There is a free space between the ends of the corresponding ribs of adjacent pairs of ribs. The ribs of adjacent ones Pairs of ribs are arranged at different distances from the bottom edge, but the edge distance of the ribs is diagonal opposite pairs of ribs is the same size. The distance between the ribs 12a, 12b or 14a, 14b of the one with the pin 8 provided corners of the container from the corresponding side walls is slightly larger than a rib width, while the Ribs 11a, 11b or 13a, 13b of the other pairs of ribs run very close to the associated side walls.

The longitudinal side walls 2 of the container are each provided with a number of holes 15 which are used, if necessary facilitate freezing of the product contained in the container.

The container construction described allows several containers of this type to be stacked in different ways. In the Figures 3 and 4 such stacking options are shown by dash-dotted lines. With normal stacking of several containers, the lower flange 5 of the respective upper container lies on the upper flange 4 'of the one below Container on. The pins of the

lower container into the recesses 10 of the upper container. Since the pin 8 or the wells 10 of the container are arranged at diagonally opposite container corners, the upper container is thereby centered on the lower container. The ribs on the underside of the upper container protrude into the interior of the lower container, with the Ribs 11a, 11b or 13a, 13b also center the upper container on the lower oil container.

A double lid container can be formed by placing two containers on top of one another with top against top the. The upper flange 4 ″ of the upper container rests on the upper flange 4 of the lower container, with two P diagonally opposite containers corner the pins 8 of the lower container into the recesses 9 ″ of the upper container and at the two other container corners the pins of the upper container into the corresponding recesses of the lower container engage and thus center the upper container serving as a lid on the lower container. The order The ribs on the bottom of the container enable such double-lid containers to be stacked on top of one another can. In such a case there are two container bottoms one on top of the other, the containers being centered in the manner shown in FIG. 3 by the ribs.

The free space between opposing ribs 11a, 14a or 12a, 13a on the long sides of the container enables the container described to be stacked in connection with half-size containers. In such a case, one large container is placed on top of two next to each other Lying half-size containers are placed on top, the latter being held in place by the ribs of the large container. The half-sized ones Containers do not have any protruding pegs, since such pegs would prevent them from being stacked with the bottom against the top the lower flange of the large container rests on the upper flange of the half-large container.

The free space between the ribs 11b, 12b or 13b, 14b on the narrow sides of the container is made possible on the one hand the. Use of quarter-size containers, on the other hand, when stacking half-size containers with their Bottoms on the underside of a large container as a water drain.
