COVER SYSTEM FOR CONTAINER FILLED WITH CONCENTRATED PRODUCT Russian patent published in 2024 - IPC B05B11/00 B65D81/32 

FIELD: transportation; packaging; storage.

SUBSTANCE: invention relates to a cover system. Technical result is achieved by cover system, which contains cover unit (200), containing inner wall (202), defining tube (203) passing through cover unit (200). Outer wall (204) surrounding inner wall (202) and spaced from inner wall (202) to define circumferential cavity (214a, 214b) between inner and outer walls (202, 204). At that, cover assembly (200) comprises sealing element (208) to seal tube (203). Closure element (208) comprises upstream side (208a), downstream side (208b) and support surface (220) on its downstream side (208b). Closure element (208) is tightly attached to inner wall (202) by brittle joint (210) located between ends of tube (203). At that, brittle joint (210) passes in the first plane perpendicular to longitudinal axis (A) of tube (203). System comprises plug (300) containing tubular body (302) with open near end and open far end. At that, the open proximal end is surrounded by first rim (304), which comprises the proximal thrust surface (305), for thrusting against support surface (220) of closure element (208). At that, plug (300) comprises flange (310) extending outward and provided with thrust surface (312) for abutment of rim (406) of replenished vessel (400). Wherein plug (300) can move from the first position, in which thrust surface (305) is located downstream of brittle joint (210), to the second position, in which thrust surface (305) is located upstream of brittle joint (210), in order to destroy brittle joint (210). Thrust surface (305) is configured to rest against the support surface of the closure element when the plug is moved from the first position to the second position so that the resultant force applied to the closure element acts along the longitudinal axis (A) and perpendicular to the first and second planes. Closure element (208) is hollow and tapers from downstream base (219) to upstream top (218).

EFFECT: providing safe and convenient storage and transportation of fluid medium.
