A fluid dispensing valve structure for dispensing the viscous contents of a pressurized container. The structure incorporates a tiltable elongated tubular nozzle which, when tilted, longitudinally moves a moveable cup member in a valve chamber, away from a seal, thereby opening the valve. Fluid from the container passes transversely through a side opening in the valve chamber over a top region of the moveable cup member and into the nozzle during dispensing.

A fluid dispensing valve structure for dispensing the viscous contents of a pressurized container comprising: a valve mounting cup peripherally sealingly securable to said pressurized container and having wall portions defining an interior valve receiving chamber with a central upper aperture defined therein; a resilient seal member positioned around and radially adjacent said aperture in said valve receiving chamber; an elongated tubular nozzle means having a dispensing orifice in one end thereof and having a second opposed and radially outwardly flanged end extending through said central aperture and yieldingly sealingly supported by said resilient seal member in a normally generally straight upright extended position relative to said valve mounting cup; a moveable valve cup means reciprocally longitudinally slidably carried within said valve receiving chamber 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 said 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 valve plate portion position to extend across said second end having perimeter regions, (B) annular rib means upstanding from valve plate portion for engaging said resilient seal member peripherally of said second end, and (C) sidewall means for slidably guiding said moveable valve cup member relative to said wall portions in said valve receiving chamber during said reciprocal sliding movements; aperture means defined in said side wall portions generally axially adjacent said resilient seal member and generally radially adjacent said second end for passage of said viscous contents therethrough to said second end in a generally radial direction relative to said wall portions; the interrelationship between said moveable valve cup means, said tubular nozzle means, said resilient seal member, and said mounting cup member being such that a substantially unobstructed flow of said contents through said valve structure and across said base portion occurs when said one end is so tiltably displaced.
