ABSTRACT:
A combined anti-refilling and pouring device for use in association with a bottle incorporates a tubular casing having at one end a tubular extension formed with inwardly directed radial fins and an annular flange presenting a center hole projecting inwardly beyond the fins at the outer end of the extension. A ring member having radially disposed fins extending axially from one end face of the ring is located within the tubular casing with the fins on the ring member terminating close to the fins in the tubular extension. A movable valve member is trapped within the axial passage defined by the tips of the radial fins in the tubular extension between the fins on the ring member and the annular flange, the valve member being free to engage the center hole and close it, and a ring of deformable material having a maximum diameter greater than the internal diameter of the neck of a bottle into which the device is to be fitted encircles the tubular casing.
