CORKING MEANS WITH CAP Russian patent published in 2021 - IPC B65D47/08 B65D50/04 

FIELD: packaging.

SUBSTANCE: corking means (1) has cap (2), which is installed with the possibility of rotation on corking means (1) by means of hinge (3). Protrusions (12, 27) are formed on sides of corking means (1) and cap (2), which protrude outward when cap (2) is closed due to the protrusion of cap (2) transversely to the closing direction. Thus, protrusions (12) on corking means (1) slide along the outer edge and then engage due to the elastic inversion of a bulge. Cap (2) is then fixed to corking means (1) in a sealed and reliable manner. Cap (2) with its front area rests with its edge (11) on ledge (9) on corking means (1). This edge (9) can slide along the plane of ledge (9) when pressing on the front area in the direction of hinge (3). This creates a two-sided bulge of side edges (10) of cap (2) so that protrusions (26) on cap (2) detach from protrusions (12) on corking means (1). Then, after that, cap (10) can be rotated to the open state when rotating around hinge (3) by continuously pressing on its front area with the elastic inversion of bulges after pressure is removed.

EFFECT: obtaining the corking means with the cap.
