Reclosable valve with separate internal seal means and seal removing means therefor
First Claim
1. In a fluid preassemblable valve structure of the type suitable for dispensing the contents of a pressurized container associatable therewith, said valve structure comprising:
- a valve mounting cup peripherally sealingly securable to said pressurized container and having generally continuous wall projections extending generally internally into said container and defining an interior valve receiving chamber with a medial upper portion having a central aperture defined therein;
an elongated tubular nozzle means having a dispensing orifice in one end thereof and having a second end extending through said central aperture;
a resilient valve seat means positioned in said valve receiving chamber;
a moveable valve means positioned in said valve receiving chamber and biasable against said valve seat means to close and seat said valve structure;
said tubular nozzle means being moveable responsively to force applied to said one end so that said second end unseats said moveable valve means to open said valve structure;
the improvement which comprises in combination;
a sealing plate means positioned across said wall projections and closing said valve receiving chamber;
a releasable bonding means adhering said sealing plate means to adjacent portions of said wall projections in gas tight relationship, and adapted to release said sealing plate means from said wall projections responsively to pressure applied against said sealing plate means from a location in said valve receiving chamber;
said sealing plate means and said bonding means in combination with said wall projections being effective to isolate said contents from said tubular nozzle means, said valve seat means, and said moveable valve means,engaging means associated with said moveable valve means for abutting against said sealing plate means; and
the interrelationship between said sealing plate means, said tubular nozzle means, said moveable valve means, and said releasable bonding means being such that an initial movement of said tubular nozzle means moves said moveable valve means with said associated engaging means against said sealing plate means to permit a release of said bonding means and a separation of said sealing plate means from said wall projections, thereby to permit operable association between said contents and said valve structure for dispensing said contents.

Abstract
A reclosable moveable valve stem actuated valve structure for an aerosol-type viscous fluid dispensing container. The valve structure is provided with an initially sealed internal seal and a valve stem operated internal seal removing component. The valve structure is preassembled before association with the container. The seal includes a seal plate and releasable bond. The seal removing component is associated with a moveable valve member. The moveable valve member is operated initially by movement of the moveable valve stem and causes the internal seal removing component to effectuate a release of the releasable bond, thereby opening the initially sealed internal seal.

18. A fluid dispensing valve structure for dispensing the viscous contents of a pressurized container comprising:
-
a valve mounting cup member; peripherally sealingly securable to said pressurized container, having generally continuous first wall portions defining a centrally located aperture, having a cup-like member with a mouth and generally continuous second wall portions defining sides and base, said cup-like member including fastening means mounting mouth adjacent second wall portions thereof circumferentially about said aperture, said base having an opening centrally defined therein; a resilient seal member positioned radially adjacent said aperture interiorly of said cup-like member, an elongated tubular nozzle means having a dispensing opening in one end thereof and having a second opposed and outwardly flanged end supported relative to said valve mounting cup member by said resilient seal member in a normally generally straight upright extended position; a moveable valve cup member reciprocally longitudinally slidably moveable within said cup-like member and normally biasable against said resilient seal member to form a seal means for normally sealing the contents of said container, said moveable valve cup member being engageable with said second end, said contents of said pressurized container being dispensable when one end is tiltably displaced relative to said generally straight upright extended position by an external deflecting operating force applied thereagainst, thereby opening said seal means, said moveable valve cup member including; (A) a base portion extending across said second end of said tubular nozzle means, (B) annular rib means upstanding from said base portion for engaging said resilient seal member peripherally of said second end, (C) guidance means for guiding said moveable valve cup member relative to said cup-like member during said reciprocal sliding movements, and (D) projections means for extension through said opening during said reciprocal sliding movements; aperture means defined in said sides axially adjacent said resilient seal member for passage of said contents therethrough to said second end in a generally radial and transverse direction relative to said sides; a sealing member positioned over areas of said first and said second wall portions including said aperture means; releasable bonding means adhering portions of said sealing member to areas of said wall portions in a gas tight sealing relationship, said bonding means being adapted to release said sealing member from said wall portions responsively to pressure applied against a portion of said seal member by said projection means; said sealing member and said bonding means in combination with said wall portions being effective to isolate said contents from said tubular nozzle means, said resilient seal member, and said moveable valve cup member; the interrelationship between said sealing member, said tubular nozzle means, said moveable valve cup member, and said releasable bonding means being such that an initial movement of said tubular nozzle means moves said moveable valve cup member with said associated engaging means against said sealing member to permit a release of said bonding means and a separation of said sealing member from said wall portions, thereby to permit operable association between said contents and said valve structure for dispensing said contents; and the interrelationship between said moveable valve cup member, said tubular nozzle means, said resilient seal member, said mounting cup member and said sealing member being such that a substantially unobstructed flow of said contents through said valve structure and into said second end occurs when said one end is so tiltably displaced and said sealing member is so separated from said wall portions. - View Dependent Claims (19, 20)
