Description

The invention relates to containers for storing perishable products, mainly. agricultural.

Famous containers for storing perishable products, comprising a housing, an insert, a window with a gas-selective membrane and two gas pipelines for introducing protective gas [1].

A disadvantage of the known packaging is that the shielding gas is unevenly distributed in the production volume and, due to the diffusion nature of gas concentration equalization, the time to establish a uniform concentration is large, and this leads to product deterioration.

The purpose of the invention is to increase the safety of perishable products.

This goal is achieved by the fact that in a container for storing perishable products, comprising a housing, an insert, a window with a gas-selective membrane, and two gas pipelines for introducing shielding gas, gas pipelines are placed at different heights on opposite sides of the housing and have a variable length permeability to ensure uniform flow gas.

FIG. 1 shows the proposed packaging, general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows the node I in FIG. one.

The container consists of a housing 1, inside of which is placed an insert 2 of polyethylene or polymer film, equipped with a window with a membrane 3 and an air-permeable partition 4. Membrane 3 Made of a gas-selective material.

The partition 4 is made of a material with impregnation with a suspension of activated carbon in a solution of an antiseptic preparation.

At different heights at opposite sides of the housing 1 are fixed Two gas pipelines 5 with openings 6, ensuring uniform gas flow along the entire length of the gas pipeline 5. Holes 6 in gas pipelines 5 can be made, for example, in the form of slots (openings), whose dimensions gradually increase along gas movement. Gas pipelines 5 are equipped with check valves 7 and quick disconnect couplings 8 installed in front of the entrance.

The check valves 7 are made of two spring-loaded flaps 9, pressed against the seat 10, made of elastic material.

The quick-detachable connections of the pipes 8 are made in the form of flat steel flanges 11 fixed on gas pipelines 5 and flat circular permanent magnets 12 made in the shape of flanges 11 fixed on connecting elastic pipes 13, with the help of which gas pipelines 5 tare are connected to the ventilation unit and the gas source environments (not shown). Inside the container can be placed boxes 14.

Depending on the type of product, the membrane 3 and the partition 4 can be located on different sides of the housing 1 and the liner 2 (top, bottom, side).

The operation of the container is as follows.

Products, depending on their type in bulk or in boxes 14, are placed in liners 2 cases of 1 container.

The pipes 13 are connected to the gas pipeline 5 by contacting the flanges 11 with the magnets 12. They turn on the ventilation unit and the source of the gas medium and perform the initial forced injection of gas, for example carbon dioxide, into the cavity of the liner 2. This opens the valves 9 of the waste valves 7 along the way gas movement.

Due to the fact that the gas pipelines 5 are located at different levels on opposite sides of the case and have slots (openings) of variable cross-section, a uniform gas flow is ensured along the entire length of the gas pipelines 5. As a result, these products in the container are treated with gas evenly.

After processing products in the insert

2 containers set a certain concentration of the gas medium and the pipelines 13 are disconnected. In this case, check valves 7 close the gas pipelines 5. Membrane

3 provides for the establishment of a high content of protective gas, and a low oxygen content, which leads to inhibition of biological processes in products and lengthening the shelf life of the latter.
