Stackable and nested containers for food, in particular meat and meat products

The invention relates to a stackable, nested one Containers for food, in particular meat and meat products, the wall of which is conical from the bottom to the container opening expanded, the bottom of which is essentially twice the width of the stacking support longer than the container opening is wide and its stacking devices on two opposite wall parts of the broad sides of the elderly in the area of the opening edge of the container extensions as receptacles and stacking shoulders for the bottom area of a container rotated by 90 are trained.

In the case of the known containers of this type, it is disadvantageous that stiffening and supporting ribs are provided on the outside of the container his iiiüsosn, däöo ternary of the Ecliältsrumfarigcrancl for stiffening is folded in the shape of a vial or semicircular shape and that Support elements in the form of support ribs and support feet on the container bottom or an outer adjusting edge surrounding the container bottom are provided. All of these to stiffen the familiar Elements provided in the container make cleaning difficult of the container and form corners and edges from which accumulating food particles and dirt are very difficult to remove leave.

In contrast, the invention is based on the object to provide a stepelable and nestable container that does not have Has corners and edges that are formed by webs, ribs or other stacking and stiffening elements. Rather, it should the container easily and thoroughly by hand or in a machine, can be cleaned, in particular the container should not have any corners or edges on which there are any residues or dirt can accumulate. Another object of the invention is to provide an improved storage and transport container For foodstuffs to create sufficient ventilation of the container inside even in a stack of containers enables, in particular, according to the invention

Cross-stacking of the containers be possible and also when stacking crosswise, the containers are exactly placed one on top of the other be guaranteed so that in a stack of containers the vertical center axes of all containers as precisely as possible in one common vertical stack axis coincide and so even relatively high stacks do not tend to tip over.

The object set is achieved according to the invention by: that the opposing wall parts of the container below each recording and the stacking shoulder with one after the The exterior of the container is pulled forward towards the bottom of the container extending, on both side edges opposite the respective recording on the stacking shoulder as a lateral step offset. ; Wall area are formed, which on each side edge over a downwardly extending strip-shaped, for example Vfand section arranged at right angles to the container wall merges into the container wall.

In the case of the container according to the invention, the bottom of a second container stacked on a lower container is initially rotated 90 ° with respect to the bottom of the lower container and received between two outer wall parts which extend downward over each broad side of the container. With a particularly simple structure, this stacking device ensures that

-A-

the bottom of the second container stacked on the lower container is held in two container wall portions, whereby all containers in the stack are aligned with the stack-.i> .- v..se and do not allow yourself to be sniffed out of this position. The bottom cross-section can be much smaller than the opening cross-section of the container, so that the container is well ventilated despite a stacked second container "remains. The one provided for the container according to the invention Stacking device is also sufficiently rigid and strong to be proportionate to absorb large load pressures from one or more containers stacked above.

It is quite possible that the protruding wall area extends to the bottom of the container. However, preference will be given to choosing an embodiment of the invention in which the one below the wall area lying on the stack receptacle only up to a distance above the floor with respect to the respective side wall part is pulled outward and there over a strip-shaped horizontal wall section in the container wall transforms. In this embodiment, the container according to the invention can be transported very favorably by known transport devices grasp and pick up with fork-shaped carriers and easily and safely on transport and storage facilities with lateral Guide steering and stabilizing rollers. In this embodiment, the container has a good appearance and also has a high sta-

bilitat. In another embodiment of the invention proceeds the outwardly protruding wall area obliquely downwards towards the container wall and opens at a distance above of the container bottom into the surface of the container wall. In this embodiment too, the container wall is on the broad strings continuously smooth in the lower area.

In all embodiments of the invention, the floor can be smooth, ie. be designed without standing ribs, feet or edge, so that the container can easily be kept clean in the area of its bottom. The stacking device is provided in all Embodiments of the invention free of ribs and webs. There are only anticipated parts provided, the wide, Form accessible rooms and can therefore be cleaned very easily and thoroughly. The strip-shaped transition pieces between your outwardly protruding wall area together with the container wall and the protruding wall area, a support profile which is suitable for placing considerable loads on the container wall to be removed.

It is advantageous within the scope of the invention if the container opening surrounding, after the container exterior protruding peripheral edge is formed flange-like flat. Through this

entfalle- \ kc \ i any annular cavities as they are known in -.ehältern with wülstformig or semicircular uisgc = opening edge placed usual. The container according to the invention can thus always be kept clean under its opening edge.

The handles of the container are also within the scope of the invention trained in a special way. For this purpose, in the upper area of the container wall, relatively large, opposite, horizontal slots designed as handles, on each of which a handle shell on the upper half of the peripheral edge are molded on the outside of the container in the form of a strip folded downwards at each end. The grip plate takes only the top half of the circumference of the opening. This leaves the handle is much easier to keep clean or rinse, because jets of water etc. can reach all parts of the smiley face unhindered Handle shell hit what with one as a handle naschel around the whole Grip opening molded strips would not be guaranteed.

It is particularly advantageous if the downwardly directed end edges of the handle shells are at the desired box spacing are arranged below the opening edge of the container. In this way, each grip shell forms two supporting edges, which are used as Tray stop can be used and when nesting

FIG. 7: a third embodiment of the container according to FIG Invention in side view and

FIG. 8: two stacked containers according to FIG. 7 % in front and side views.

The examples shown are recording and transport containers for meat and meat products for use in butcher shops, sausage factories and others meat processing companies are intended. The containers are designed with walls that are as smooth as possible and a smooth, level bottom. The containers according to the invention do not have any corners that are difficult to access and are formed by webs and ribs narrow cavities.

In the example of FIGS. 1 to 4, the container has an essentially rectangular, flat, smooth base 1, of from which the four peripheral walls 2a, 2b, 2c and 2d widen conically upwards to the edge of the container opening 3. The Andes Walls 2a, 2b arranged on the narrow sides of the container are essentially flat, while those on the broad sides of the container

ordered walls 2c and 2d in their central area 4 so far outwardly are preferred that the distance between the opposing outwardly protruding wall parts 4 is somewhat is greater than the length 5 of the container bottom 1. In the area of the container opening edge 3, these outwardly protruding wall parts 4 are to a somewhat greater extent than the width 6 of the Container bottom 1 expanded. This creates pocket-like stacking receptacles 7 formed downwards by an approximately quadratic Shoulder 8 formed in the container wall is closed off will. For stacking, there is one container opposite the one below To twist the container by 90 and to insert the corner areas of its container bottom i into the pockets 7 and open to put the shoulders 8 down. The stacking pockets 7 grip around the ur.teren corner areas of the container side walls 2a, 2b, 2c and 2d, so that a secure stacking of the containers is guaranteed is. Due to the basic rectangular shape of the container, there are still essentials on both sides of the attached container Free parts of the opening of the lower container, so that an advantageous air circulation for the container contents is guaranteed is.

Below the shoulder 8, the side walls 2c and 2d go over strip-shaped strips extending downward to the container bottom 1 Wall sections 9 in the protruding wall parts 4 over. These

- 10 -

Wall sections 9 are essentially at right angles to the side walls 2c "or 2d and the protruding wall parts 4 are arranged and thereby form an exerted on the shoulders G. Load supporting and on the container walls 2c and 2d and the container bottom 1 distributing angular profile.

As can be seen in particular from FIG. 2, all the necessary corners 10 and edges 11 can be inside, but also on the outside of the container must be rounded.

In the examples shown, the container has four handles, which are formed by relatively wide, semicircularly rounded slots 12 in the container walls 2a, 2b or the outwardly protruding wall parts 4 of the container walls 2c, 2d. These slots 12 lie with their upper edge in the plane defined by the shoulders 8 or just below it, so that when the containers are stacked on top of one another, the slots 12 remain free and contribute to the circulation of air. With their lower edge, the slots 12 form a marking for the maximum filling height ^{1 of} the container, so that when stacking one on top of the other a sufficient distance is ensured between the bottom underside of the upper container and the contents of the lower container noticeable air circulation through the slots 12 takes place.

- 11 -

On the outside of the container is above each slot a grip shell in the form of a strip-shaped element 13 molded. This strip-shaped element 13 extends to its two ends 14 along the rounded ends of the slot 12 down in a quarter circle. In the illustrated Example ends the strip-shaped grip shell 13 in the determined by the center lines of the slots 12 plane. As a result, the downwardly directed edges 15 form the strip-shaped Grips 13 support stops that are nested when nested of containers on the opening edge 3 of the lower container. This gives each container eight Support stops 15 lying in one plane, which effectively prevent wedging of the nested containers. the Handle shells 13 form in nested containers still an engagement opening 16, corresponding to half the height of the slot 12, which allow the fingertips to be inserted around the nested containers Separate groups.

A secure support around the edges 15 is provided in the case of ineinanäerge ^ chacb! This ensures that the opening edge 5 V of the container with an outwardly extending flange - J

like smooth peripheral edge 17 is surrounded. '

In the preferred embodiment:,:> :: m ^ .he invention according to FIG 5 and 6, the container of the Aur ^ führungebeispiel differs according to Figures 1 to 4 essentially in the fact that: ._ .α outside advanced wall parts 4 in a distance 18 above the container bottom are essentially withdrawn onto the container walls 2c and 2d over a strip-shaped, horizontal wall area. At this distance 18 above the container bottom, all container walls 2a, 2b, 2c, 2d are drawn in approximately by the wall thickness and thus additionally stiffened somewhat. This offers the possibility of guiding the container according to FIGS. 5 and 6 on transport devices which are provided with lateral stabilizing and guide rollers, or to use it in known flow racks which have lateral guide and guide rails. The strip-shaped horizontal wall areas 19 formed at the lower end of the protruding wall parts 4 also offer the possibility of grasping and lifting containers according to FIGS. 5 and 6 with transport or stacking devices with fork-shaped carrier elements.

In the somewhat modified example according to FIGS. 7 and 8, in contrast to the example according to FIGS. 1 to 4, those according to externally protruding wall parts 4 "2?. To create such a hatred more conical than the container walls 2c, 2d that
