CONTAINER FOR DRINKS Russian patent published in 2010 - IPC B65D41/08 

FIELD: packing industry.

SUBSTANCE: container for drinks comprises container body, including hole, cover for closure of hole and collar installed on container body. Body comprises one or more retaining parts, by means of which the collar may be retained on it, until cover is removed. Collar comprises multiple valves or other parts distanced from each other along its circumference length. Cover and collar include interacting fastening facilities, by means of which the cover may be fixed to collar, at the same time interacting fastening facilities include multiple thread elements distanced along circumference, both on cover and collar, so that the collar may be installed inside cover by means of axial displacement of collar relative to cover with further rotary motion between them for engagement of according thread elements. Specified thread elements on inner side of cover are arranged with such a shape so that specified valves or other parts of collar are pressed radially inside due to cam action, when cover is rotated relative to collar, so that specified valves or other parts of collar tightly fix one or more retaining parts of container body, while cover is attached to container body, and cover rotation relative to collar by means of specified thread elements also results in cover pulling into tight engagement with hole of container body. Cover and collar are provided to close container body.

EFFECT: new design of container for drinks is convenient to use, eliminates possibility of spontaneous cover untwisting under effect of higher pressure inside container, when container content is pressurised.
