Abstract

An aerosol valve structure for introducing a propellant gas under pressure from a filling head into a pressurized container of the type that is provided with a driving button, without removing this from the container; characterized in that the actuating button has a hollow stem which is provided with an opening at its inner end and in which said valve assembly has a cover element provided with a central protrusion, a valve cover, a plunger with an end of valve seat, a spring and an annular elastomer seal set in the lower face of the crown of the central protrusion, there being a central opening in the protrusion and a passage in the joint, and the stem extending through the opening and of the aisle, and said valve assembly being normally closed since the valve seat end of the plunger is pressed against the joint, but being open so as to facilitate communication between the valve casing and the opening of the actuator stem when the drive button is pressed to separate the valve seat end from the meeting; said structure being characterized in that said central opening (58) made in the protrusion (23) of the lid element (16) has a generally circular non-circular shape defining a plurality of support points (74) to substantially guide the stem ( 56) and the lateral compartment means (76) that are not sealed by the stem, the seal (32) having sufficient elasticity to allow its intussusception around said central opening (58) when the propellant gas under pressure penetrates through the compartment device (76) from the outside of the protrusion, while pressing the actuator button (22).
