Abstract

The folding container according to the invention used for distributing a flowing substance, includes a pair of generally rigid walls, interconnected by sheet-shaped walls and o edge. The container can be arranged extended, with rigid walls spaced apart from one another the other and in the foldable state with the rigid walls generally arranged, parallel, forming a flattened device. Rigid walls ensure, in generally a marker area for container.

Description

The invention relates to a foldable container for the distribution of a flowing substance.

A foldable container is known for distributing a variety of materials, from toiletries to food items. The material can be of high viscosity, although a liquid or fluid substance may also be distributed.

A

For the same purpose, a variable volume tank is also known, having a main use as a fuel supply system, made of a pair of spaced panels, intersected with a sheet-shaped structure such that the panels move towards each other on as the tank folds.

The disadvantages of these types of containers are that they require large storage and transport spaces, they can be economically loaded only over relatively small distances.

The object of the invention is to increase the productivity of the loading-unloading process in small spaces, when transporting empty.

The problem solved by the invention is to obtain a reliable container, easy to fold in empty, unloaded transport condition.

The folding container, according to the invention, removes the disadvantages mentioned in that it consists of a pair of generally rigid walls, interconnected by folding walls that can be arranged in an extended or flat form, depending on the actual situation (loaded or unloaded), having a fill-emptying opening.

According to the present invention, a container is formed by a pair of walls, generally rigid, interconnected by folding walls. The folding walls can be arranged in extended form when the container is fully distributed.

A

In one embodiment, the folding walls form a base with rigid walls projecting upward from the base. To load the containers, the rigid walls are moved to one another so that the container generally forms a flat folded device. The container has an opening through which it can be filled and through which the material can be distributed. The rigid walls can be folded or with a progressively curved configuration. The surface of the rigid walls provides an excellent base for marking.

When the container is filled, the base has its largest surface and as the material is distributed, the base continues to form a suitable support.

During loading, the folded container may be loaded at a minimum volume. This feature ensures not only the economic loading, but also the storage of the containers until they are ready for use.

Containers can be secured in a variety of forms so that in a filled state they can be compactly stored without wasted space. Suitably, in folded or filled condition, containers can be packed efficiently.

In folded or extended state, the container has at least a fixed size. Depending on the shape of the container when expanding, it can have two fixed dimensions.

In a preferred embodiment of the container in the extended state, the cross-section of the transverse container on its height or parallel to the base is usually triangular. The folding walls, placed between two with the flattened base, form a narrow rectangular shape.

The various novel features that characterize the invention are pointed out, in particular, in the appended claims, forming part of this description. For a better understanding of the invention, the specific working advantages and objectives achieved by their use, reference should be made to the accompanying drawings and descriptive material, in which preferred embodiments of the invention are described and illustrated.

In the following, an embodiment of the invention is given, in connection with FIG. 1 ... 5, which represents:

FIG. 1, elevation view of a container representing the present invention;

FIG. 2, elevation view of the container shown in fig. 1, rotated by 90 ° and with a distribution mouth;

FIG. 3, a view similar to fig. 2, of the container in the folded state flattened and without the distribution mouth;

FIG. 4, perspective view of the container, generally taken in the same direction as FIG.

FIG. 5, perspective view of the container, taken in the opposite direction to fig. 2.

The collapsible container, according to the invention, consists of a base 1 and some side walls 2 and 3 planar interconnected to the base 1 and along the height of the side walls of some folding walls 4. The side walls 2 and 3 are joined along corresponding edges through a connecting edge 5. The container is provided with a nozzle and an alternative arrangement of a hole 7 filling. An opening 8 is placed at the top of the container for filling it with a flowing substance, from which a mouth may be attached to form a distribution opening.

To distribute the contents, the rigid side walls 2 and 3 are pressed to each other and the content flows through the mouth 6. Depending on the type of material to be distributed, the nozzle 6 can be provided as a seal that allows the flow of the content, without any input. air when performing the distribution operation.

A Gerber valve can be used for the distribution of sterile substances.

The surfaces of walls 2 and 3 are flat or flattened however, it would be possible to secure the walls with a break, generally flattened, to receive markings.

The side walls 2 and 3 are interconnected by the edge 5 so that they can pivot relative to each other, from the extended condition shown in fig. 2 at the folded or flattened state shown in fig.3.

The placement of the edge 5 along the height or at the top of the side walls 2 and 3 depends on the desired configuration of the container.

The container can be made of a variety of plastics, such as polyethylene.

The folding walls 4 have a sheet shape and extend between and interconnect the side walls 2 and 3. The folding walls 4, in relation to the mouth 7 of distribution, allow an arrangement with the complete distribution in full of the substance in the container.

in FIG. 2 in extended state, the flat walls 4 in sheet form, defining the base of the container, are arranged in such a way that the adjacent surfaces of the container are in a divergent relationship. When the container is empty, either before or after it is filled, the rigid walls pivot inwards towards each other, from the position shown in fig. 2, in completely flattened state shown in fig. 3, the basal part of the flat walls 4 is shown folded in a flattened state and is shown between the side walls 2 and 3.

The foldable container can be formed by a blow-molding operation, without the distribution mouth, so that the container can, in a completely flattened state, be packed in boxes and loaded at any required distances. When the containers are ready to be used, they can be filled with a flowing substance and the dispensing mouth can be attached 6 and 7. A person familiar with the technology will readily appreciate that, the configuration of the container can vary for both functional and aesthetic reasons.

The advantages of applying the invention are:

- increasing the productivity of the loading-unloading process;

- decrease of the spaces occupied for storage and transport.
