METHOD AND DEVICE FOR FILLING-IN BY GAS AND HERMETIC SEALING OF CHANNEL INTENDED FOR THIS PURPOSE LOCATED IN COLLAPSIBLE CONTAINER AND CONTAINER BLANK WITH SUCH CHANNEL

摘要

FIELD: transport; packing. ^ SUBSTANCE: collapsible container contains channel intended for filling-in by gas. Channel is formed by two opposite walls connected along connection lines and it contains inlet element located in one of side walls. Part of container containing inlet element is clamped between detent and gas module capable of axial shift to detent. Clamping is made as follows: one of two side walls forming channel protrudes in response to supply of gas from gas module with gas entering channel via said inlet element allowing free penetration of gas filling in channel. Upon completion of filling-in by gas channel is sealed. Invention also refers to container blank with such channel. ^ EFFECT: container acquires stability and does not require sophisticated equipment for filling-in by gas. ^ 21 cl, 4 dwg
