[0053]A typical aerosol can or container (as at 11) contains two substances. One substance is an inert gas used as a propellant 12. The second substance is a liquid product 13, such as a lubricant, to be delivered by way of the propellant 12. The inert gas or propellant 12 is at high pressure and essentially pushes on the product 13 such that the product 13 travels through the container conduit 14 and exits the container 11 via a container outlet 15 as generally depicted in FIG. 18 via a product flow path generally depicted by arrows 100.

[0054]The aerosol can or container 11 is valved such that the product 13 cannot escape the aerosol can or container 11 until the valve is opened, usually by pushing down on its nozzle. A container conduit 14 extends from the valve, which is at the top of the aerosol container 11, to the bottom of the aerosol container 11. If the valve is opened and the aerosol container 11 is upright, the product 13 is pushed by the pressurized inert gas 12 through...

Abstract

A valve and / or repair kit assembly restores functionality to an aerosol container by being selectively and removably attachable the annular container rim adjacent the container outlet, which has been damaged or otherwise compromised. The valve assembly comprises a container-to-assembly interface fitting and a plunger assembly. The fitting interfaces the plunger assembly to the container, which plunger assembly comprises a sleeve, a nut, and a plunger structure. The sleeve comprises communicating cavities in which the nut and plunger structure are received. The plunger structure is coupled to the nut, each of which provide certain conduit. The fitting axially aligns the plunger assembly with the container outlet and matter-conducting conduit thus extends from the container outlet to the assembly outlet via the valve assembly. Certain methodology for discharging container contents is further supported by the valve assembly.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention generally relates to a valve assembly for selective and removable attachment to an aerosol container. More particularly, the present invention relates to a valve assembly for selective and removable attachment to a standard aerosol container for salvaging container contents from said container, which container has been damaged or compromised at its container outlet.[0003]2. Description of Prior Art[0004]The prior art is fairly silent on replacement valve constructions for aerosol can dispensers and the like. Several of the more pertinent art disclosures, however distant or distinctive, are briefly described hereinafter. For example, U.S. Pat. No. 3,638,840 ('840 Patent), which issued to Ishida, discloses a Safety Valve for Aerosol Containers. The '840 Patent describes a safety valve for an aerosol container which permits the discharge of the residual propellant gases in a used container when the va...
