LID WITH ANGLED BEVELED SURFACES ON INNER AND OUTER PARTS Russian patent published in 2013 - IPC B65D41/62 B65D45/00 B65D45/32 B65D55/02 

FIELD: packaging industry.

SUBSTANCE: lid (22) comprises an inner part (28) and an outer part (24). The inner part (28) is made with the ability to receive the bottle stopper ring (20) and comprises several extending outwards first beveled surfaces (32) which are located at an acute angle to the longitudinal axis of the lid (24). The outer part (24) of the lid is made with the ability to put substantially at its inner part (28), at that the outer part (24) comprises several inwardly extending second beveled surfaces (34) which are located at an angle to the longitudinal axis of the lid (22). The outer part (24) is made with the ability to move relative to the inner part (28) between the open position, in which at least some section of the outer part (24) makes at least some section of the inner part (28), resting against the bottle neck, resist to removal of the inner part (28) out of engagement with the stopper ring, and the open position in which the inner part (28) enables to remove the inner part (28) out of engagement with the stopper ring. In the case when the outer part (24) is in the open position, the application of longitudinally directed force to the outer part (24) respectively aside from the inner part (28) causes longitudinal movement of the outer part (24) relative to the inner part (28) towards the open position as the first beveled surfaces (32) perform a longitudinal movement respectively aside from the second beveled surfaces (24), and the rotation of the outer part in the first direction about the longitudinal axis relative to the inner part (28) causes longitudinal movement of the inner and outer parts towards the open position as the second beveled surfaces (34) move respectively along the first beveled surfaces (32).

EFFECT: lid is easy and convenient to use.
