Document Type and Number:
Japanese Patent JP6670316
Kind Code:
B2
Abstract:
The present invention concerns a stopcock for allowing or stopping the flow of a liquid under pressure through a dispensing tube (13) comprising an upstream portion (13u) separated from a downstream portion (13d) by the stopcock to which they are both connected, said stopcock comprising
(a) A housing portion (11) comprising a chamber (11c) defined by a housing peripheral wall surrounding a longitudinal z-axis, said housing peripheral wall comprising an inner surface of revolution provided with a housing inlet opening connectable to the upstream portion (13u) of the dispensing tube (1 3),
(b) An outlet connector (11d) connectable to or forming the downstream portion (13d) of the dispensing tube and comprising an outlet opening;
(c) A plug (21) defined by a plug outer peripheral wall snugly fitting the inner surface of revolution of the housing peripheral wall, such that the plug can rotate within the chamber (11c) about said longitudinal z-axis, said plug comprising
(d) a through-channel (23) extending from an upstream opening (23u) located on the plug outer peripheral wall, to a downstream opening (23d), such that the plug can be rotated about the longitudinal z-axis from a flow position to a sealed position,
Characterized in that, the plug outer peripheral wall comprises a seal protrusion (22s) topped by a ridge and forming a closed loop defining a blank area (23s) of the peripheral wall, such that, in the sealed position, the housing inlet opening of the housing peripheral wall faces the blank area (23s) and is circumscribed within the seal protrusion (22f).
