LIQUID FILLING INTERFACE FOR A BOTTLE AND SYSTEM CONTAINING SUCH AN INTERFACE

Abstract

Liquid filling interface (10), comprising: - an actuator comprising an axial piston (34) having a body (36) and a head (38) having an elastically deformable portion (38a) and comprising: a liquid circuit (46) having an inlet (O1) adjacent to the head (38) and an outlet (O2) opposite the head (38), and a separate air circuit having an inlet (O3) disposed between the inlet (O1) and the outlet (O2) and an outlet (O4) adjacent to the head (38), - a rigid barrel (20) in which the piston (34) slides axially between: a position where the head (38) cooperates with an internal surface of the barrel (20) to make a tight contact with the portion (38a), and a position where the head (38) is moved away from this surface to create a free space communicating with the inlet (O1) and the outlet (O4).
