ABSTRACT:
A pressurized container (1) for a viscous product, comprising a container body (2) with an opening (9), a piston (3), a dispensing closure (4) attached to the container body opening (9) which comprises closure walls, at least one dispensing aperture (13), at least one closing element (14) that is movable relative to the closure walls between a closed position and an open position, the container (1) further comprising a spring element (15) disposed between said closing element (14) and said closure walls, so as to naturally force the closing element (14) in a position where it closes said aperture (13), wherein the closure walls define a channel (16) with at least one lateral dispensing aperture (13) remote from the container body opening (9), said closing element (14) having the shape of a ring that seals around and is movable relative to the channel (16), by translation along, or by rotation around, an axis which is parallel to the longitudinal axis of the channel (16).
