Description

The utility model relates to the field of transportation and storage of goods and is intended for use as containers for granular, lumpy and other bulk goods.

Flexible containers are widely known and are used for storage and transportation of dry bulk food and non-food products and materials such as sugar, animal feed, cement, sand, dry mixes, mineral fertilizers, granular polymer materials and almost any other products and materials.

So, as a soft container, a collapsible container for transporting pasty and granular goods is known, protected by German patent No. 1140856, IPC B65D 88/16, publ. 06.12.1962. The known collapsible container is cylindrical, having a blank bottom on one end part, and on the other end part in the bottom there is a loading and unloading device in the form of a tube with a valve valve. The known collapsible container is made of synthetic material and is placed in a power mesh with lifting loops. As a rule, soft containers are made of polypropylene or nylon (polyamide) fabric, which is cost effective and expedient, however, due to insufficient rigidity, such a design of the capacity of a soft container leads to its instability.

Known soft container, the design of which is protected by RF patent No. 2540788, IPC B65D 88/22, B65D 88/16, B65D 33/02, publ. 02/10/2015. The known soft container contains an insert with upper loading and lower unloading openings, a frame power mesh with lifting loops formed by alternating rows of vertical belts and horizontal annular belts with the formation of upper and bottom parts. The frame mesh is additionally equipped with obliquely arranged and made crossing ribbons, each of which is rigidly connected to each row of horizontal annular ribbons, starting from the upper and ending with the lower row. This design provides increased rigidity of the frame mesh, which holds the soft container itself, however, there is a risk of lateral fall when the filling height is exceeded, in addition, the technological process of manufacturing such a frame mesh is rather complicated, which is not economically feasible.

The closest analogue of the utility model is a soft container for transportation and storage of bulk cargo, protected by RF patent No. 2188785, IPC B65D 88/16, publ. 10.09.2002. The known soft container contains a container with an upper loading opening and a lower unloading opening, a power grid with lifting loops, a bottom and a closure device. The capacity of the known soft container is placed in a power grid and is connected to it in the upper part by means of a detachable connection. The latter consists of loops connected in series with each other, fixed on the container and on the power grid with the closing of the last group of loops with a cord tie. Moreover, the continuation of the loops, fixed on the container, are made in the form of tapes placed obliquely to the direction of the warp and weft threads of the container fabric. The known flexible container provides an increase in ease of use, however, its main disadvantage is its low rigidity, which causes its insufficient stability.

The task to be solved by the utility model is to increase the stability of the flexible container by increasing the rigidity of the lower part of the outer wall of its container.

The technical result of the proposed technical solution is the development of a flexible container design, more stable, and therefore safer in operation.

This problem is solved due to the fact that the proposed soft container for transportation and storage of bulk cargo contains a container with an upper loading opening and a lower unloading opening, a locking device, a power grid with lifting loops formed by alternating rows of vertical belts and horizontal annular belts, and a bottom. The lower part of the outer wall of the container, adjacent to the bottom, is provided with fabric ribbons rigidly attached to it, placed obliquely to the direction of the warp and weft threads of the container fabric and made intersecting. The angle of inclination of the intersecting fabric tapes rigidly fixed on the container with respect to the direction of the warp and weft threads of the container fabric is 30 °. The height of the lower part of the outer wall of the container with intersecting rigidly fixed fabric bands is 300 mm.

Such a design of the lower part of the outer wall of the container of the flexible container makes it possible to increase its stability. The increased rigidity precisely in the lower part of the outer wall of the container provides a condition for safe work with such a container, since it reduces the risk of the container falling sideways and overturning.

The present invention and its advantages will be better understood by reference to the following detailed description and the accompanying drawing. The drawing shows a general view of a flexible container for transportation and storage of bulk goods with intersecting inclined belts in the lower part of the outer wall of the container.

A flexible container for transportation and storage of bulk cargo contains a container 1 with an upper loading opening 2 and a lower unloading opening 3, a power grid 4 with lifting loops and a bottom 5. The container 1 is located in a power grid 4. A (lower) sleeve is attached to the unloading opening of container 1 with a tape loop 6 for pinching, which is locked with a hairpin 7. On the lower part of the outer wall of the container 1, fabric tapes 8 intersecting with each other are rigidly fixed.

The flexible container for the transportation and storage of bulk cargo works according to a well-known technology. The upper loading opening 2 is connected to the factory line, through which the container 1 is filled with bulk material. The loaded soft container, delivered to the unloading site, is suspended by the lifting loops of the power grid 4. The power grid 4 traditionally serves as a frame for the soft container and consists of interconnected annular horizontal belts that absorb the expanding force of the bulk cargo, and vertical belts that hold the bulk cargo on weight. When suspended, the power mesh 4 of the soft container is in a loaded state. For unloading, the pin 7 is uncoupled, the tape loop 6 releases the squeezed area of the unloading hole 3, and the bulk material is poured from the soft container into the vehicle.

The intersecting inclined belts 8 are made of the same materials as the container 1 of the soft container, for example, from polypropylene or nylon (polyamide) fabric. The intersecting tapes 8 are rigidly attached, for example, but not limited to, they are soldered to the lower part of the outer wall of the container 1, occupying a height of mainly 300 mm from the day 5 of the container 1. The angle of inclination of the intersecting fabric tapes 8 rigidly fixed to the container with respect to the direction of the threads the warp and weft of the fabric of the container 1 is preferably 30 °.

Inclined belts 8 can intersect at any point in their length. The drawing shows one, but not limited to this, variant of the intersection of fabric tapes 8, fixed (soldered) on the lower part of the outer wall of the container 1.

This design provides a higher rigidity of the container 1 of the flexible container, and, accordingly, a higher dimensional stability of its lower part.

Thus, the above information indicates the fulfillment of the following set of conditions when using this utility model:

the means embodying this utility model during its implementation relates to the field of transportation and storage of goods and is intended for use as containers for bulk goods;

for the above soft container as it is described in the independent claim of the utility model, the possibility of its implementation is confirmed;

the means embodying the utility model in its implementation helps to increase the stability of the generally soft container by increasing the rigidity of the lower part of the outer wall of its container.

Consequently, this utility model meets the “industrial applicability” condition.

To confirm the possibility of implementing the utility model, a prototype of the above-mentioned soft container has been manufactured and successfully tested.
