Description

Technical area

The present invention relates to a container according to the preamble of claim 1, in particular to a container for transporting goods on roller conveyors with a base, side walls and a support plate connected to an underside of the base via ribs.

State of the art

Generic containers are known from, for example
DE 10 2008 020 916 A1 or DE 10 2013 207 943 B4 . These containers each have a base with a rectangular outline, side walls extending vertically upward from the base and a support plate which is connected to an underside of the base via ribs.

The problem with these containers is that they generate relatively loud noises during transport on roller conveyors due to the contact of the stable bond between the floor and the support plate with the rollers of the roller conveyor.

The object of the present invention is therefore to provide a container which enables quieter transport on roller conveyors.

This object is achieved by the features of claim 1. Advantageous further developments are the subject of the subclaims.

A container according to the invention has a base, side walls and at least one support plate connected to an underside of the base via ribs.

The side walls extend from an upper side of the floor transversely, in particular perpendicularly, upwards to the floor.

The support plate is spaced from the underside of the floor and extends in particular parallel to the underside of the floor.

The ribs, which connect the at least one support plate to the underside of the base, extend transversely, in particular perpendicularly, to the base or to the underside of the base and transversely, in particular perpendicular, to the support plate.

The container according to the invention is characterized in that at least two projections protrude laterally on at least one edge section of the support plate that extends along one of the side walls. In particular, the projections each have the shape of a plate. In particular, the projections are designed such that they each have free ends on three sides and are connected to the support plate on a fourth side.

In other words, the container according to the invention is characterized in that at least two projections are formed on the at least one support plate in such a way that the support plate together with the at least two projections at least partially form an outline with a crenellated outer contour.

In particular, the plate-shaped projections each have a rectangular or a substantially rectangular or trapezoidal or substantially trapezoidal outline. In particular, one edge of each plate-shaped projection with a rectangular outline is connected to the at least one support plate. In particular, three of the four edges are of each plate-shaped projection with a rectangular or trapezoidal outline free or at least partially free.

By providing the projections, the deformability of the support plate can be increased locally. In addition, when the container is transported on a roller conveyor, direct impact of the support plate on rollers can be made more difficult or prevented.

In the upper edge section of the at least one side wall, at least two support depressions are provided for receiving at least two projections of a support plate of a structurally identical container stacked thereon.

In other words, at least that side wall along which the at least one edge section of the at least one support plate, each provided with at least two projections, extends, has at least two support depressions on an upper side in a particularly upper edge section facing away from the bottom, which are designed in such a way that they each receive a projection of a support plate of an identical container in a state in which the identical container is stacked on the container.

The projections increase the outer dimensions of the support plate, so that more rollers can be touched by the container at the same time during transport on a roller conveyor compared to a container with a support plate without lateral projections. Thus, a more stable and thus quieter transport behavior can be achieved. By providing support depressions, the excess by which the projections protrude laterally can advantageously be increased without impairing the stacking properties of the container.

At least one of the at least two projections can be connected to the underside of the floor via at least one rib extending transversely to the floor and transversely to the at least one support plate. In particular, the the rib connecting the projection and the underside of the base extend perpendicular to the base or to the underside of the base and / or perpendicular to the support plate.

By providing the rib connecting the projection and the underside of the base, the local increase in deformability caused by the free ends of the projections can be limited.

The at least one rib, which connects the bottom to one of the at least two projections, can have a wall thickness which is less than an average wall thickness of the container. Additionally or alternatively, the at least two projections can have a wall thickness which is less than the average wall thickness of the container. The wall thickness of the at least one rib connecting the base to one of the at least two projections and the wall thickness of the at least two projections can be the same. Alternatively, the wall thickness of the at least one rib connecting the base to one of the at least two projections can be smaller than the wall thickness of the at least two projections. In this context, “wall thickness” is understood to mean the thickness of plate-shaped components, for example the plate-shaped rib or the plate-shaped projections. In particular, the wall thickness of the rib connecting the base to one of the at least two projections and / or the projections can be less than a wall thickness of the base or a wall thickness of the side walls.

By locally reducing the wall thickness, the flexibility of the container can advantageously be increased locally, so that when the container is transported on a roller conveyor, an impact on rollers can be dampened. Such an improved impact behavior can alternatively or additionally also be achieved by a local reduction in the density of the ribs connecting the floor to the projections. In this context, "density of the ribs" is understood to mean the number of ribs per predetermined uniform area of the plate-shaped projections.

At an edge section of the at least one support plate which is opposite the edge section of the at least one support plate provided with the at least two projections, at least two laterally protruding projections, in particular each in the form of a plate, can also be formed. In other words, at least four similar projections according to the invention can be provided on the at least one support plate. Those of the side walls along which the edge sections of the at least one support plate, each provided with at least two projections, extend, can be in a position facing away from the floor, i.e. in particular have at least two support depressions in each case in an upper, edge section on an upper side. The support depressions can be designed in such a way that they each receive a projection on a support plate of a structurally identical container in a state in which the structurally identical container is stacked on the container.

If projections are provided on two opposite sides of the at least one support plate, a noise-reducing effect can not only be achieved if the container is moved in a single specific orientation on a roller conveyor.

On the side walls, each provided with at least two support depressions, in each case in the area facing away from the floor, i.e. in particular the upper, edge section on an outside of the respective side wall between the corresponding at least two support depressions, at least one handle can be formed.

On the side walls each provided with at least two support depressions in the area of each support depression on the outside of the corresponding side wall, an outwardly extending bulge can be formed. The at least two handles can each be designed as a rib extending transversely, in particular perpendicular, to the corresponding side wall between the at least two bulges of a corresponding side wall.

Undersides of the at least four projections of the at least one support plate can extend in a common plane. Lower surfaces of the at least four support depressions can extend in a common plane. A distance between the common plane of the undersides of the at least four projections of the at least one support plate and the underside of the base can be less than or equal to a distance between the common plane of the lower surfaces of the at least four support depressions and an upper edge of the container. This design of the support depressions or the projections can advantageously ensure that the container does not rest on the projections when it is stacked on an identical container.

At edge sections of the floor, which extend along edge sections of the at least one support plate, each provided with at least two projections, at least one column extending transversely, in particular perpendicular, to the floor or to the underside of the floor, can be formed which extends downwards less protrudes far from the container than the at least one support plate and protrudes to the outside or to the side less far from the container than the at least four projections on the at least one support plate. In particular, the columns can be formed at corners of the floor. The edge sections facing away from the bottom, in particular the upper edge sections of the side walls, each provided with at least two support depressions, and the corresponding support depressions can be coordinated with the projections on the support plate and the columns in such a way that in a state in which the container is stacked on a structurally identical container Lateral displacement of the container in relation to the identical container is limited and / or prevented by interaction of the columns with an inside of side walls of the identical container and the projections of the at least one support plate of the container do not touch the inner surfaces of corresponding support depressions of the identical container. This coordination allows the projections to be protected from stress when stacking several identical containers. In the vertical direction, a stacked one on a container can be identical Container introduced force can be derived over the upper edge of the container and can derive lateral forces introduced from the identical container in the lateral direction or in lateral directions the columns of the container.

The ribs, which connect the at least one support plate to the underside of the container, can have openings. Due to the openings, the ribs can be easily formed.

The openings cannot be arranged mirror-symmetrically to one another. The non-mirror-symmetrical arrangement of the openings can make it difficult for acoustic waves and / or vibrations to propagate.

The openings in the ribs can be arranged rotationally symmetrically to one another in relation to a central axis of the container extending perpendicular to the bottom. In particular, the openings can be designed and arranged in such a way that they are mapped onto themselves when rotated through 180 ° about the central axis. The construction of the container or of the tools can be simplified by a rotationally symmetrical arrangement.

The projections can be coated with a material or made of a material which is softer than a material or than materials of the other parts of the container. The material of the projections can thus advantageously be optimized for damping an impact on rollers of a roller conveyor without impairing the structural integrity of the remaining container parts.

The base, the side walls, the at least one support plate and the ribs connecting the base and the at least one support plate can be formed in one piece. Complex assembly steps can be saved through a one-piece design.

The container can be made of plastic. Plastic is advantageously suitable for fields of application with high hygiene requirements, for example for food.

The at least one support plate can have at least one opening. In particular, the at least one support plate can have a central opening so that the support plate essentially has the shape of a ring. In particular, the annular support plate extends along the edges of the floor. In this way, the container can be made of lightweight construction and can still be placed on a flat surface in a stable manner.

The bottom can have a substantially rectangular outline. The side walls can have two opposite long side walls arranged on long edges of the base and two opposite short side walls arranged on short edges of the base. The container can be designed in such a way that projections are formed only on edge sections of the at least one support plate that extend along the long side walls. If a container with a rectangular floor plan is transported on a roller conveyor, noises are generated in particular when the container is transported with one of its long side walls first. If projections are only provided on the support plate on the long side walls, a noise-reducing effect can be achieved with relatively few adjustments.

Detailed description of preferred embodiments

Fig. 1 shows a container 2 according to the invention in a perspective view obliquely from above. Fig. 2 shows the container 2 according to the invention in a perspective view obliquely from below.

As in Fig. 1 and Fig. 2 As shown, the container 2 has a bottom 4 with a substantially rectangular outline, from the long edges of which two opposite long side walls 6 and 8 extend upwards and from the short edges of which two opposite short side walls 10 and 12 extend upwards. Each side wall 6, 8, 10 and 12 each has a substantially rectangular outline.

Provided below the base 4 is a support plate 14 which extends at least essentially parallel to the base 4 and is connected to an underside of the base 4 via ribs 16.

The support plate 14 has the outline of a substantially rectangular ring and is dimensioned such that outer edges of the support plate 14 extend parallel to the edges of the base 4.

The ribs 16 extend perpendicular to the base 4 or perpendicular to the support plate 14. In addition, the ribs 16 not only extend between the support plate 14 and the base 4 but also reinforce the base 4 in an area within the annular support plate 14.

On the outer edges of the support plate 14, which extend along the long side walls 6 and 8, projections 18 are formed. Each of the two corresponding outer edges each have two projections 18. Each of the protrusions 18 has the shape of a plate with a trapezoidal outline. The projections 18 are each connected with their long base side or base to the support plate 14 in such a way that they each locally lengthen the support plate. This means that the support plate 14 and the projections 18 lie in a common plane. Furthermore, the projections 18 have a chamfer on their short base side on an underside.

The projections 18 are each connected to the underside of the base 4 via two ribs 20. The ribs 20 run perpendicular to the underside of the base 4 or perpendicular to the respective projection 18.

The outer edges of the support plate 14, which extend along the short side walls 10 and 12, each have a bevel on the underside of the container 2. The shape of the chamfer on the outer edges of the support plate 14 along the short side walls 10 and 12 corresponds to the chamfer on the short base sides of the plate-shaped projections 18. The ribs 16 and the ribs 18 are designed in such a way that several Ribs are lined up parallel to one another in such a way that they form outwardly open pockets 22 between them and together with the underside of the base 4 and an upper side of the support plate 14 or an upper side of the projections 18.

The ribs 12 are furthermore designed in such a way that one of the ribs 12 connects an inner edge of the annular support plate 14 to the underside of the base 4. The pockets 22 are delimited inwards by this circumferential rib. As in Fig. 3 As shown, openings 24 are provided in the circumferential rib which are arranged rotationally symmetrically with respect to a central axis M running perpendicular to the base 4. Within the inner edge of the annular support plate 14, the ribs 12 are arranged in the manner of a framework.

At each of the corners of the base 4 a column 26, hereinafter referred to as a corner column 26, is formed. The four corner pillars 26 each connect a long side wall 6 or 8 with a short side wall 10 or 12.

As in Fig. 3 As shown, the outer edges of the support plate 14 and the short base sides of the projections 18 are offset inwardly with respect to the side walls 6, 8, 10 and 12. If the container 2 is stacked on an identical container, an outer edge section 28 of the bottom 4 rests on an upper edge section 30 of the side walls 6, 8, 10 and 12. So that the projections 18 do not prevent such resting, two support depressions 32 are formed on the upper edge section 30 of the side walls 6, 8, 10 and 12 per side wall. The support depressions 32 are each designed such that a distance D from an upper edge of the container 2 to a lower surface of the respective support depression is greater than a distance d between the undersides of the projections 18 and the underside of the base 4. If the container 2 is on Stacked the identical container, the projections 18 are received in the support depressions 32. The projections 18 do not touch the lateral inner surfaces of the support depressions 32 either. This is ensured by the fact that a play between the outer surfaces of the corner pillars 26 and an inner surface of the side walls of the identical container is smaller than a play between the short base sides of the projections 18 and a respective outer inner surface of a corresponding support recess of the identical container.

The support depressions 32 are implemented by bulges in the long side walls 6 and 8. This means that the long side walls 6 and 8 each have a bulge 34 on their respective outside in the region of a respective support recess 32. Between the two bulges 34 of a respective long side wall 6 or 8, a rib running perpendicular to the corresponding long side wall 6 or 8 is provided, which forms a handle 36.

In Fig. 4 a bottom view of the container 2 is shown together with schematically illustrated rollers R of a roller conveyor. If a container 2 is transported on the roller conveyor with the long side wall 6 first, the short base sides of the projections 18 first hit a corresponding roller before the remaining parts roll or slide or roll over the same roller. Because not only the short base sides of the projections 18 but also the legs of the projections 18 are free ends, at least in sections, the projections 18 are easily deformable and dampen the impact of the container 2 on the corresponding roller R.
