LID FOR A CONTAINER, DESIGNED FOR SEVERAL COMPONENTS Russian patent published in 2012 - IPC B65D47/06 

FIELD: mechanics.

SUBSTANCE: group of inventions is referred to lids for a container, designed for several components. The lid for a container, designed for several components, contains an insert, a piston and an end cup. The insert and the piston limit the chamber. The insert has an immovable cylindrical-type wall and a movable wall attached to it, which is able to move against the immovable wall under the effect of gas pressure in the chamber. There is an exhaust outlet in the movable wall. Thereby, the end cup has a closing plate, the outer edge of which is integrated with a hanging skirt which provides fastening of the end cup to the container. The closing plate interacts with the piston so that a displacement of the plate in the direction to the insert leads to the subsequent displacement of the pistol in the same direction. Thereby, the pistol forms a sliding seal with internal surface of the immovable cylinder-type wall and a valve element, which is integrated with the pistol, and placed in a position, which ensures sliding in the stated exhaust outlet and hermetically closes it.

EFFECT: construction simplicity.
