Abstract:
1. A compressible valve for use with a pressurized container for dispensing an aerosol product, the pressurized container having a longitudinal axis defining a longitudinal direction and comprising a bottle having an open top end and a dispensing structure disposed inside the open top end of the bottle, the dispensing structure having an open end coaxial with the bottle open top end, the compressible valve comprising: a. a valve cup disposed inside the open top end of the bottle, the valve cup having an open top portion, a bottom portion with an opening therein and a longitudinal passageway between the open top portion and the bottom portion opening, wherein the valve cup comprises a cylindrical portion near the open top portion, the cylindrical portion having an internal diameter; b. a grommet disposed in the opening in the bottom portion of the valve cup, the grommet having a sealing portion and spring portion, wherein the sealing portion is integral with the spring portion, a spring portion opening, a sealing portion opening, and a grommet longitudinal passageway therebetween, the grommet longitudinal passageway has an internal diameter and is coaxial with the valve cup longitudinal passageway, the sealing portion is joined to the valve cup bottom portion and provides a seal between the dispensing structure and the valve cup, the spring portion is longitudinally opposed to the sealing portion towards the valve cup open top portion, the spring portion is deformable in the longitudinal direction; and c. a valve stem disposed in the grommet passageway, the valve stem comprising an open top portion, a closed bottom portion with at least one radial opening disposed therein, a passageway between the open top portion and the at least one radial opening, and a primary flange having a top side and a bottom side disposed between the open top portion and the closed bottom portion, wherein the valve stem primary flange has a primary flange diameter that is sized close to the valve cup cylindrical portion internal diameter such that the primary flange is in sliding contacting relationship with the cylindrical portion and wherein the bottom side of the primary flange is in compressible contacting relationship with the grommet spring portion and the closed end is in radial contact with the grommet longitudinal passageway near the grommet sealing portion opening providing a seal between the at least one radial opening in the valve stem and the grommet longitudinal passageway when the valve stem is in a closed position, wherein longitudinal translation of the valve stem primary flange results in equivalent longitudinal deflection of the spring portion exposing the at least one radial opening to the aerosol product when the valve stem is in an open position.
