CORK-TYPE CLOSURE Russian patent published in 2023 - IPC B65D47/08 

FIELD: e-commerce.

SUBSTANCE: closure device, especially applicable to e-commerce. Closure comprises a lid and a cap base that can be detachably attached to the container, the cap base including an opening. The lid has a plug extending from it, placed in a hole in the base of the cap when the lid is in the closed position. The hole is formed in the wall of the cylindrical hole. When the lid is in the open position, one or more hook-like tabs extend outwardly from the outlet plug at its end farthest from the lid. When the lid is moved to the closed position with the outgoing plug inside the wall of the cylindrical hole, the hooks are pressed against the walls of the plug and placed in a recess in the wall of the cylindrical hole. Inside the recess, the hook-like tabs are pressed to the upper wall of the recess so that additional force is required to open the lid, for example during transport.

EFFECT: when a consumer desires to open the lid, they apply an additional force required to open the lid, causing the hook tabs to return to their original positions in which they extend outward from the cylindrical plug.
