LID ASSEMBLY FOR CONTAINER REFILLED WITH CONCENTRATED PRODUCT Russian patent published in 2024 - IPC B05B11/00 B65D81/32 

FIELD: refillable containers.

SUBSTANCE: invention relates to a lid assembly for a refillable container. The technical result is achieved by a lid assembly (200) for a refillable container, which contains an inner wall (202), a defining tube (203) passing through the lid assembly (200), an outer wall (204), a surrounding inner wall (202) along the first part thereof length, with the outer wall (204) spaced from the first part of the inner wall (202) to define a circumferential cavity (214) between the inner and outer walls (202, 204), a connecting wall (212) extending between the inner and outer walls (202, 204), wherein the cap assembly (200) includes a closure element (208) configured to seal the tube (203), wherein the closure element (208) includes an upstream side (208a), a downstream side (208b) and a support surface (220) on its downstream side. The closure element (208) is sealed to the inner wall (202) by a peripheral frangible connection (210). The peripheral frangible joint (210) extends in a plane (P) perpendicular to the longitudinal axis (A) of the tube (203). The inner surface of the inner wall (202) upstream of the closure (208) is offset radially from the inner surface of the wall (202) downstream of the closure (208). In this case, the container body (100) contains an opening surrounded by a rim (108), which abuts against the connecting wall (212) of the lid assembly (200).

EFFECT: providing a safe and convenient supply of fluid into a refillable vessel, wherein the assembly can be simply and reliably connected to the refillable vessel for releasing concentrated liquid into the refillable vessel.
