Description

The technical field to which the utility model belongs.

The utility model relates to containers, and more particularly to folding containers for storing items, including the bottom and side walls made in the form of separate cardboard sheets, and means for connecting these elements to each other, which provides folding of the side walls at the junction, while the bottom made with the possibility of changing position relative to the side walls.

In this description, the concepts of “upper” and “lower” are used, which are catchy and are used only to simplify the understanding of the product structure. In the static unfolded version of the container, it is assumed that it is located on a horizontal surface perpendicular to gravity, for example, on a table, with its bottom touching this surface. The edge of the side walls, which is located near the horizontal surface, is called “lower”, the opposite edge is called “upper”. These concepts in this position of the container fully correspond to the generally accepted interpretations of the words “upper” and lower ”, but in any other position of the container, for example, in the folded position, the upper and lower edges are conventionally named.

The level of technology.

Known from the prior art, a folding container for storing items, including the bottom and side walls made in the form of separate cardboard sheets and means for connecting these elements to each other, folding the side walls at the junction, while the bottom is made with the possibility of changing position relative to the side walls, see the description of the patent for the invention No. 2057690, published in 1996.

This device is the closest in technical essence to the claimed utility model and is taken as a prototype for the proposed utility model.

The disadvantage of this device is the insufficient strength of such a container, for example, it cannot be dropped, it will change shape, it cannot be wetted, as it will not be able to hold the contents. In addition, such a container has a large weight, which is undesirable. That is, the real utility model is designed to solve the problem of the fragility of such a container.

Disclosure of a utility model.

The present utility model, based on this original observation, mainly aims to offer a folding container for storing items that allows at least to alleviate the above drawback, namely, to increase the strength of the container while ensuring low weight and increase the useful life, which is the set technical task of this utility model.

To achieve this, the connecting means is made in the form of a fabric bag located on the entire inner surface, holding the bottom, connected along the upper perimeter with an additional external flexible casing made of a single tape consisting of interwoven strips wound on the side walls, while the adjacent edges of adjacent the rows of tape are stitched together, with the side walls located between the fabric bag and the outer casing.

Due to this advantageous characteristic, it becomes possible to increase the strength of the cardboard container, since there is a fabric bag holding the bottom inside the container and an lightweight tape casing outside, which also allows folding the container walls. Really:

- the execution of the casing of the tape makes the container prone to folding anywhere

 - the walls of the cardboard provide the rigidity necessary for the container to hold the form in the unfolded position, while having a low weight,

- the fabric bag fixes the bottom, while also having a low weight.

It is clear that if wet, the fabric bag inside into a lightweight casing made of tape on the outside will ensure that the container retains its function. Even though the walls of the cardboard are wet, the container will not lose its shape.

It is also clear that due to the proposed features, the collapsible container can be repeatedly dropped onto a hard surface, it remains intact.

There is a possible embodiment of the utility model, in which the bottom has a means of gripping and pulling the bottom. Thanks to this advantageous characteristic, it becomes possible to increase the usability of the container.

In addition, there is a possible embodiment of the utility model, in which the bottom is removable.

Thanks to this advantageous feature, it becomes possible to completely remove the bottom when folding the container.

There is another possible embodiment of the utility model, in which the fabric bag is attached to the lower edges of the side walls along the entire perimeter, has a diagonal cut, which provides folding of the side walls by converging two opposite vertical edges of the container, and the bottom is attached with one side to the lower edge of the side wall through fabric bag, with the possibility of folding the bottom inside the container

Thanks to this advantageous characteristic, it becomes possible to fold the container while maintaining the low weight of the entire device.

There is also a possible embodiment of the utility model, in which two side walls located opposite each other have a bend in the middle, which provides folding inside the container by converging the two opposite side walls of the container, and the corresponding cardboard rectangular sheets are made of two equal halves located on opposite sides from the fold line of said side walls.

Thanks to this advantageous characteristic, it becomes possible to alternatively fold the container while maintaining the low weight of the entire device.

There is an embodiment of the utility model, in which the bottom is made in the form of a cardboard rectangular sheet, sheathed on both sides with fabric.

Thanks to this advantageous characteristic, it becomes possible to manufacture the bottom from cardboard, which also leads to the low weight of the entire container.

There is another possible embodiment of the utility model, in which two side walls located opposite each other have handles for carrying in the form of through slots having a metal or plastic edging. Due to this advantageous characteristic, it becomes possible to conveniently carry such a container when unfolded.

The set of essential features of the proposed utility model is unknown from the prior art for devices of a similar purpose, which allows us to conclude that the criterion of "novelty" for the utility model is met.
