ABSTRACT:
A valve assembly for a container for pressurized fluid in which a cup (10) mounts the assembly to a container body, and a valve (14) including a valve housing (12) fitted in the cup, the valve housing is located within the cup by the engagement of internal projections (16) in the cup behind a head (18) of the housing. The cup, the valve housing (12) and the valve (14) are arranged in one condition of the valve assembly to allow fluid to be passed into the cup and between an exterior wall of the housing and the side wall of the cup for filling the container. The exterior wall of the housing is provided with a multiplicity of narrow grooves (26) which define flow paths (62) for the passage of such fluid and these grooves are narrow in relation to the width of the internal projections, so that they do not impair the locating function of the projections. The grooves extend into a collar (20) on the housing adjacent to the head, and because of their narrowness they provide extra flow paths past the projections which contact this collar, which paths cannot be blocked by the projections irrespective of the orientation of the housing relative to the cup.
