ABSTRACT:
Valve (10) for the discharge of fluids which are under pressure, especially liquids, pastes, creams or gels or the like, with a discharge tube which can be moved in a valve body out of a closed position against the action of a resilient member, especially a helical compression spring, to which tube a pot-like closing member (12), working together with a ring seal made of rubber or the like and closely surrounding the discharge tube (11), is allocated. The discharge tube (11) has, on its opposite end from the discharge aperture (13), a surrounding ring projection (14) with axial indentations (15) which can be snapped into a corresponding ring undercut (16) of the pot-like closing member (12).
