CONTAINER PLUG HAVING STRUCTURE WITH MULTIPLE LOCKING ELEMENTS Russian patent published in 2019 - IPC B65D51/18 B65D47/08 B65D39/04 

FIELD: package and storage.

SUBSTANCE: invention relates to container plug having structure with multiple locking elements, in which structure with multiple locking elements is located on inner peripheral surface of hole in lower part of plug and on outer peripheral surface of sealing projection of upper part of plug, connected to it, thereby preventing easy opening of connected plug under the action of shaking or other external forces occurring during distribution or storage of product. To this end, a container plug is provided, comprising a plug bottom part 100 connected to container inlet 11; a plug upper part 120 selectively opening and closing hole 111 formed in the plug bottom part 110; and which comprises at least two locking portions 130 spaced from each other in the insertion direction on the inner peripheral surface of opening 111 in lower portion 110 of the plug and on outer peripheral surface of sealing projection 121 of upper part 120 of plug, connected to inner peripheral surface of hole 111.

EFFECT: invention makes it possible to form the main position of locking the upper part of the plug in the hole of the lower part of the plug, thus preventing easy opening under the action of external shocks and increasing strength of seating of the upper part of the plug by using locking parts in at least two points on the outer peripheral surface of the sealing projection.
