ABSTRACT:
A two piece valve accessory for common caulking tubes or cartridges insertable in caulking guns is disclosed. The valve permits resealing of the cartridge nozzle, snout or applicator tip without hardening or significant wastage of the material therein and permits increased control of the flow rate of material from the cartridge.
The valve is adjustable from fully open to closed position and includes a separate sealed or dome extended position wherein the residue from the applicator tip of the valve is expelled.
The valve barrel includes an integral piercing edge to break the cartridge seal as the valve is inserted into the applicator tip of the cartridge. The barrel is sized and ribbed for an interference non-rotatable fit within the applicator tip. The valve cap is fully rotatable on the barrel and includes a beveled tip to direct material in any radial direction relative to the caulking gun handle.
In use the valve is opened and caused to remain open by pressure applied to the cartridge by the caulking gun plunger. The valve is closed or fully closed and sealed manually after release of the pressure on the material in the cartridge.
