Description

The utility model relates to packaging and can be used as part of shipping containers for placement, storage and transportation of 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, while 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 disadvantages of the known technical solutions is that the lid falls into the contents of the package and, as a result, the lid is deformed under the influence of condensate settling on it and sticking to it of part of the contents as a result of whipping when moving containers after pouring molten oil products.

When unpacking the contents of a frozen product, the part of the lid that is in the contents is torn off and remains in the product.

When melting and pumping oil, the torn off parts of the cover get stuck in the pump and pumping pipelines and lead to disruption of the process.

The task is to prevent the lid from falling into the contents of the liner bag, as a result of its wetting and softening.

The technical result provided by the utility model is to prevent deformation of the rigid cardboard non-removable cover of the liner bag, subsequently wetting and softening it under the influence of condensate, moisture and whipping the contents when loading liquid hot products and moving them.

The specified technical result is achieved by the fact that the bag-liner is collapsible for the transport container, containing a non-removable rigid cardboard cover made of rigid sheet material, a bottom made of a material based on corrugated cardboard and papers, and side walls, and the bottom and cover have internal siliconized coatings , additionally, the lid has a filling hole and holes for packing tapes.

On FIG. 1 shows a container liner bag.

On FIG. 2 shows the shipping container with the liner bag installed.

The foldable bag-liner for the transport container contains a non-removable rigid cardboard cover 1 made of a rigid sheet material, a bottom 4 made of a material based on corrugated cardboard and papers, and side walls 3. The bottom 4 and the cover 1 have internal siliconized coatings, on the sides facing inward liner bag.

In this case, the lid 1 has a filling hole 2 and holes 5 for pulling packing tapes 6 through them under the lid 1 when the liner bag is installed in the shipping container and fastened with packing tapes.

The transport container, for which the liner bag according to the proposed utility model is intended, can be made non-folding or collapsible.

The liner bag is stored folded.

The implementation of the utility model is illustrated by the following examples.

Liner bags were made for a transport container for bitumen with a volume of 1082 liters with a non-removable cover 1, side walls 3 made of three-layer paper with an inner layer of siliconized paper and a bottom 4.

The liner bag is installed in the shipping container. With the help of packing tapes 6, which are threaded into the holes 5 of the lid 1, the liner bag is fixed in the container. The container is fixed on the pallet 7 according to FIG. 2. Fill through the filling hole 2 of the cover 1 with hot bitumen in a liquid state to a level of 3-4 cm below the upper edge of the shipping container.

When using, namely, transporting containers with the claimed liner bags, not a single case of significant deformation of the cover 1 and its immersion during its movement and storage until cooling was found.

Claims (1)

Collapsible bag-liner for a transport container, containing a non-removable rigid cardboard cover made of rigid sheet material, a bottom made of a material based on corrugated cardboard and papers, and side walls, the bottom and cover having internal siliconized coatings, additionally the cover has a filling hole and holes for packing tapes.
