KEG POLYMER CONNECTING ELEMENT Russian patent published in 2020 - IPC B67D1/08 

FIELD: chemistry.

SUBSTANCE: keg polymer connecting element for fluid connection of inner part of container containing hole with fluid medium tube; at that, connecting element of keg comprises: (a) connection element main part (1a); (b) interfacing means (5) for reliable and detachable connection of the main part of the connecting member to the opening of the container; (c) support member (13) configured to move in the longitudinal direction Z relative to the main portion by sliding one of the support element sliding surface (13s1) relative to one of the primary main part (1a) sliding surface (1s1), wherein said support member 13) rigidly supports: (d) tube (4b, 6b, 400b) comprising a portion with a penetrating end parallel to the longitudinal axis Z and suitable for penetration into the opening; (e) actuator (15) for penetration for reversible movement over a predetermined distance along the longitudinal axis Z of support member (13) and the tube when support member (13) moves when main part (1a) is connected to the above opening, from the first retracted position (Z0) to second connected position (Z2), wherein said distance is sufficient for penetration of said penetrating tube end into said hole provided in sealing device of said container, characterized in that surfaces (1s1, 13s1) of sliding both said main part of connecting element and said support element are made of dispersed-hardened polymer material, and wherein polymer material of main part of connecting element is strengthened by disperse material, different from disperse material, which strengthens support element.

EFFECT: disclosed is a keg polymer connecting element.
