RU215024U1 - POLYMER PACKAGING FOR PLACING IN A TRANSPORT CONTAINER DURING STORAGE AND TRANSPORTATION OF MELTING PETROLEUM PRODUCTS - Google Patents

Abstract

The utility model relates to a polymer container designed to be placed in a transport container during storage and transportation of melted petroleum products, including oil bitumen, tars. The technical result provided by the utility model is to prevent leakage of the molten product by impregnating the walls of the package. At the same time, the polymeric container can easily be inserted into a rigid container having the shape of a rectangular prism and take its shape. The specified technical result is achieved by the fact that the polymer container is made in the form of a rectangular prism and includes walls glued together, a bottom made of a polymer film, and a cover made of multilayer corrugated cardboard, and the bottom has a cardboard reinforcement located on its outer side and in shape corresponding to the shape the bottom of the rigid container into which the plastic container is to be inserted. Polymer containers are made by flat assembly, as a result of which it is obtained in a folded form. 4 ill.

Description

The utility model relates to packaging and can be used both independently and as part of transport containers for placement, storage and transportation of both bulk and melted petroleum products, including oil bitumen, tars.

Known soft container for medium-tonnage shipping containers [Patent RU No. 192029, IPC B65D 77/06, publ. 08/30/2019], containing a shell (1) having vertical walls and a bottom (2), said vertical walls consist of several layers of paper: the first, which is internal, the second, which is intermediate, and the third, which is external, while the said first layer is from the inside provided with an anti-adhesive coating, said second layer is made of sack paper, and the ends of said layers are glued together and overlapped with said bottom.

Known paper multilayer bag-liner collapsible for a shipping container [Patent RU No. 150591, IPC B65D 77/06, publ. 20.02.2015], containing a bottom, a lid and side walls, the bottom is made in size and shape corresponding to the size and shape of the bottom of the transport container, the side walls are made with the possibility of folding along the fold lines, and the lid has a flanging and a neck opening. Moreover, the bottom and cover are made of multilayer corrugated cardboard, and the side walls are made of multilayer with an inner paper layer having an inner anti-adhesive coating and outer layers made of sack paper.

The disadvantage of these known packages is the possibility of leakage of the contents of the molten product in it by impregnation of its paper walls.

Known polymer package for packaging hot and sticky substances from a film based on polyethylene terephthalate (PET) with glue seams, characterized in that the PET film is made with an anti-adhesive silicone coating, and the glue for the seams is taken on a silicone basis [Patent RU No. 205845, IPC B65D 30 /08, B65D 85/00, publ. 08/11/2021].

The disadvantage of this package is that it is of an indefinite shape, does not have a definite shape of the bottom and there is no lid. As a result, when they are used as an insert for melted petroleum products, the molten petroleum product can splash out and, after solidification, part of the contents of the product ends up in the folds of the package, which are formed due to the discrepancy between the shape of the insert and the shape of the container where it is inserted.

For the same reason, the process of its straightening is difficult in order to give it a shape close to the shape of the container.

The technical result provided by the utility model is to prevent leakage of the molten product by impregnating the walls of the package.

At the same time, the polymer container can be easily inserted into a rigid container having the shape of a rectangular prism and taking its shape.

The specified technical result is achieved by the fact that the polymer container includes walls and a bottom made of a polymer film, as well as a lid made of multilayer corrugated cardboard, and the bottom has a cardboard reinforcement located on its outer side, made in the form of a rigid package bottom. The amplifier is made of various shapes, corresponding to the shape of the bottom of the rigid container, where the polymer container will be inserted.

On FIG. 1 shows a polymeric container as part of a rigid container.

On FIG. 2 shows a polymer container in a folded position.

On FIG. 3 shows a polymer container in a half-open position.

On FIG. 4 shows the polymer container in the expanded position.

The polymer container is made in the form of a rectangular prism, the walls 1 and the bottom 2 of which are made of a polymer film, and the bottom 2 is connected to the walls 1 and has a cardboard reinforcement (not shown in the figure) located on its outer side in a shape corresponding to the shape of the bottom 3 of the container where it should be inserted.

The polymer container also includes a cover 4 made of multilayer corrugated cardboard and has holes 5 - a larger one in the middle for loading the product, and four small ones - for fastening with a rigid container.

The parts of the polymer container, namely the ends of the walls 1 and the elements of the bottom 2, are overlapped with adhesive compositions that adhere to the materials of the parts to be glued (two adhesive compositions are used, one for the reinforcement with the bottom 2 (paper-polymer film) and the second for the connection of the bottom 2 with the ends of the walls 1 (film-film).Four walls 1 are glued together with overlapping ends, then the structure is glued to the bottom 2, and a cover 4 is glued to the ends of the walls 1 from above.

The polymeric container is made by flat assembly, as a result of which it is obtained in a folded form (Fig. 2).

To install a polymer container in a rigid package, it is placed on the upper edges of the rigid package with the bottom 2 of the polymer container inside the rigid package.

The bottom 2 of the polymer container under its weight descends to the bottom 3 of the rigid package, the polymer container is filled with air, straightened and takes the form of a rigid package (Fig. 1).

As a result of this technical solution, the creation of a simple and reliable package for storage and transportation of both bulk and melted petroleum products is ensured, which prevents leakage of the melted product by impregnating the walls of the package.
