Reusable high efficiency propellant driven liquid product dispenser apparatus
First Claim
1. A reusable and rechargeable propellant activated liquid dispensing apparatus comprising:
- (a) a liquid container having a product storage area;
(b) a propellant housing sealed in said container, said housing having a propellant storage area therein, within which is disposed a core, which core includes a pair of spaced pistons, an upper piston and a lower piston,(c) a discharge head, which functions as a spray actuator, and which head includes;
(I) means forming a venturi flow passageway in and opening from said discharge head, which means is adapted for fluid communication with both of,(II) a first channel for propellant deliverysaid first channel in fluid communication with said propellant housing, and(III) a second channel for product delivery;
said second channel in fluid communication with the product storage area of said liquid container.(d) a spray stem carrying a pair of flexible gaskets, (I) a product gasket and (II) a propellant gasket, said stem secured to said liquid container, and being in fluid communication with said discharge head, and with said first and second channels, whereinthe flow from said product storage area through said second channel is closed off by the product gasket, and the flow from said propellant storage area is closed off by the propellant gasket,whereby when said flexible gaskets are flexed by actuation of said discharge head, both propellant and product can be delivered to said discharge head.

Abstract
A reusable high efficiency propellant driven apparatus for the dispensing of liquid products, featuring a refillable product container, and a rechargeable propellant housing. The propellant housing may be moved from container to container, to dispense a plurality of products; and a non-completely dispensed container can have the product exhausted by the replacement of a spent propellant housing, with the same or a different housing that does contain propellant. The housing is disposed concentric to the container and preferably both are secured to a single cap. A dual piston construction is employed to provide a hermetically sealed propellant housing. Product and propellant deployment is controlled by the movement of a pair of gaskets.

19. A reusable and rechargeable propellant activated liquid dispensing apparatus comprising:
-
(a) a liquid container having a product storage area; (b) a propellant housing removably disposed in said container, said housing having a propellant storage area therein, within which housing is disposed a core, which core comprises a pair of spaced parallel tenons and a chamber, wherein the chamber extends downwardly into the core from the top thereof, and the chamber includes a centrally disposed throat of an lesser cross section that depends downwardly, spring loaded means disposed therein in fluid communication with said storage area, said spring loaded means adapted to deliver propellant from said storage area upon the urging of a spray stem; and
whereinsaid tenons include an upper piston and a lower piston at opposite ends thereof, one of said tenons having a channel therein in fluid communication with said product storage area; (c) a threaded cap threadedly engaged to said container; (d) a spray stem disposed through said cap into said housing and adapted to cooperate with said spring loaded means for delivery of propellant, and said spray stem being in fluid communication with the channel in one of said tenons for delivery of product. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 33, 34, 35, 38, 39)
