Description

The invention relates to a container, in particular made of flexible material, comprising a base plate, side walls protruding from the base plate and at least one reinforcement device for reinforcing the base plate and at least two side walls.

Containers for storing or transporting objects are known in many different variants. In its basic structure, such a container comprises a base plate, four side walls attached to it and a lid. The properties of the container can be influenced by the choice of the materials used and the structure, for example the thickness of the individual elements. Depending on the field of application, particularly stable or particularly light containers are preferred. In principle, it is desirable to provide a particularly light container, which usually affects the stability of the container. Containers made of soft materials such as plastic, especially with comparatively thin elements, are characterized by their particularly low weight. There are also containers that, thanks to their color, allow conclusions to be drawn about the content. For example, containers of different colors are selected to ensure that they can be distinguished. The disadvantage of this is that the container can be marked as a whole and, in the case of a large number of contents, a large number of voluminous containers with different markings must be kept available.

However, the stability of such containers reaches its limits, especially if they are comparatively heavy. When handling such containers, the side walls can twist against each other or the base plate can give way. In addition, such containers have the disadvantage that at least one side wall and / or the base plate touch the ground, which can lead to the absorption of moisture and wetness, particularly when stored for a long time. Known containers also do not allow the use of thin, for example transparent, materials, since these do not have sufficient stability.

The object of the present invention is therefore to create a particularly light container with a reinforcement device which reinforces the container in a simple and cost-effective stabilizing manner and also comprises a spacing from the ground.

This object is achieved by a container according to claim 1 and a reinforcement device according to claim 11.

Preferred embodiments are the subject of claims 2 to 10.

The container, in particular containers made of flexible material, comprises a base plate, side walls protruding from the base plate and at least one reinforcement device. The reinforcement device has a base portion which extends outside the container along the bottom plate. In addition, the reinforcement device has two fastening sections which, together with the base section, connect two opposite side walls of the container to one another.

The base portion of the reinforcement device thus reinforces the bottom plate and reduces yielding under load.

In addition to reinforcing the base plate, the reinforcement device has further advantages. So it spaced the bottom plate from the ground, which may have moisture and / or wetness. This ensures improved ventilation, which allows long-term storage, especially in basements. In this way, for example, the formation of mold is reduced or completely prevented.

The reinforcement devices can also be provided with various markings. These can be different colors, for example, which allows color coding to draw conclusions about the content. Since the reinforcement devices can be stored in a space-saving manner, it is not necessary to purchase containers of different colors, which is space-saving on the one hand and also inexpensive on the other. In the event that a container comprises at least two reinforcement devices, the marking options are thereby expanded immensely.

Depending on the size of the container, the container comprises more or fewer reinforcement devices. The individual reinforcement devices are arranged on the container at a distance from one another. The required number of reinforcement devices and the necessary distance from one another depend on the basic stability of the container without a reinforcement device and the desired overall stability. The container preferably comprises two reinforcement devices. In particular in the case of particularly elongated containers, the container can have three or more reinforcement devices.

The reinforcement device is fastened to the container via the fastening sections. Due to the attachment of the reinforcement device to two opposite side walls not only reinforced the base plate, but also the side walls.

The reinforcement device is easily detachably attached to the container.

The fastening section is advantageously arranged perpendicular to the base section.

In this way it is ensured that the base section of the reinforcement device extends along the bottom plate, while the fastening section extends along the side walls. In addition to strengthening the base plate, this also leads to strengthening the side walls. This prevents twisting in particular. The load distribution is also achieved over the entire floor slab, which leads to greater stability and resilience of the overall construction. The stability of this construction is further increased by a double complete floor plate.

The base section advantageously has a length and the container has a width. The length of the base section can correspond to the width of the container, but can also be shorter than the width of the container.

The bottom plate of the container is thus reinforced over its entire width by the reinforcing device. The reinforcement device is a separate component of the construction and is therefore easy to replace if lost, without having to completely replace the container.

The fastening section advantageously has a flexible section and a fastening device, the flexible section connecting the fastening device to the base section.

The flexible section is designed to be flexible along the length of the reinforcement device. In this way, the flexible section can be reversibly bent outwards along the length of the reinforcement device.

In the unloaded state, the flexible section is perpendicular to the base section. The fastening device arranged on the flexible section is partially arranged above the base section. The flexible section can be reversibly bent outwards along the length of the reinforcement device by an external force such that the fastening device is arranged completely next to the base section in the direction of the length of the base section.

The flexible section can be designed as long as it ensures the functionality described. For example, the flexible section is only designed as a vertical section which extends vertically upward from the base section.

Plastic has a certain brittleness, which can have a negative effect on the life of the reinforcement device. When the flexible section is bent, the integrity of the flexible section is stressed, which in the worst case can lead to the flexible section breaking off. It is therefore preferable to use materials for the flexible section that have an advantageous combination of flexibility and stability. The flexible section preferably has a vertical section and a curved section which acts as a spring. The bent portion preferably extends laterally in the direction of the length of the base portion from the base portion. The vertical section then extends upward from the bent section. Thus, the life of the reinforcement device can be improved.

The fastening device preferably has an actuating section and a hook section. The external force can be applied to the operating portion to bend the flexible portion. The reinforcing device is positively connected to the container by the hook section.

At least the hook section is preferably arranged above the base section when the flexible section is unloaded.

The fastening device preferably has an engagement surface which has a higher friction than the surface of the fastening device.

The contact surface is, for example, a layer with higher friction than the remaining surface of the actuating section. The contact surface preferably has grooves. The grooves are preferably made of the same material as the fastening device.

The reinforcement device advantageously has on the base section an underside facing away from the container, at least one friction surface being provided on the underside.

The friction surface is, for example, a layer with higher friction than the surface of the base section. The friction surface preferably has grooves. The grooves are preferably made of the same material as the base section.

The reinforcing device made of plastic, in particular plastic selected from the group of polyolefin, polyester, polycarbonate, polyamide, polyurethane, polystyrene, polyvinyl chloride, fluoropolymer, epoxy or mixtures thereof, preferably made of polyolefin, polyamide, polyurethane or mixtures thereof, is advantageous. Polyethylene, in particular high density polyethylene, or polyamide are particularly advantageous.

According to a further advantageous embodiment, the reinforcement device is made of wood or bamboo.

The reinforcing device is advantageously colored, in particular made of colored plastic.

The base plate and / or the side walls made of plastic, in particular of plastics selected from the group of polyolefin, polyester, polycarbonate, polyamide, polyurethane, polystyrene, polyvinyl chloride, fluoropolymer, epoxy or mixtures thereof, preferably made of polyolefin, polyamide, polyurethane or mixtures, are advantageous made from it. The plastic is preferably a thermoplastic elastomer. One advantage is the recyclability of the container.

The plastic is advantageously transparent, translucent and / or satin.

According to a further advantageous embodiment, the base plate and / or the side walls are made of cardboard, wood, cardboard or combinations thereof.

The bottom plate and the side walls can also be made of different materials.

The base plate and / or the side walls advantageously have a thickness between 0.1 mm and 10 mm, preferably between 0.2 mm and 8 mm, more preferably between 0.4 and 7 mm, even more preferably between 0.8 mm and 6 mm even more preferably from 1 mm to 5 mm.

According to a further embodiment, the container can be single-walled or multi-walled. This affects the thickness of the material. A multi-walled structure can consist of a composite of two different plastics, preferably glued or welded together. A double-walled material can also be used, a rib-like or honeycomb-like structure being installed between the walls. The advantages of such structures are material and weight savings and increased stability.

The reinforcement of the container with the aid of the reinforcement device makes it possible to produce a container with a particularly thin side wall, which nevertheless still has a comparatively high stability.

The container advantageously has at least two fastening recesses, which are provided on two opposite side walls, the fastening recesses being suitable for receiving the fastening device of the reinforcement device.

The fastening cutouts are preferably suitable for receiving the hook sections of the fastening device.

To attach the reinforcement device to the container, the flexible portion of the attachment portion can be bent outward by an external force along the longitudinal direction of the base portion. In this state, the fastening device is located completely next to the base section in the longitudinal direction of the base section. The reinforcement device can now be arranged on the container such that the base section of the reinforcement device extends along the bottom plate of the container and the hook sections of the fastening device are arranged at the level of the fastening recesses of the container. By releasing the external force, the flexible section bends back to its original orientation, perpendicular to the base section, and the hook sections hook into the fastening recesses.

In this way, the reinforcement device is firmly attached to the container. However, the reinforcement device can be removed from the container in the same simple manner.
