423 words
In a metered product dispensing system, a hollow container including a base having a bottom wall, spaced apart side walls and spaced apart end walls, there being a slot in said bottom wall, said slot including a narrow portion and a wider portion, a bushing depending from said bottom wall, and having a tapered fitting depending therefrom, a cover hingedly connected to said base, and said cover including spaced apart side portions, and a top that includes angularly arranged surfaces, an end of said top being hingedly connected to said base, a latch releasably connecting the other end of said cover to said base, a flexible pouch arranged in said container for holding material to be dispensed, a fitment on said pouch projecting through the slot in said bottom wall; a gun including a hollow body member having a handle on an end portion thereof, a manually operable trigger pivotally connected to said handle, a link pivotally connected to said trigger, a gear piece pivotally connected to said link, a sleeve having teeth thereon meshing with teeth on said geaR piece, a rod in said gun body and said rod having said sleeve slidably mounted thereon, a spring member connected to said gun body and said rod, a coil spring circumposed on said rod and abutting said sleeve, a frusto-conical plunger on the outer end of said rod, a flexible diaphragm adjacent the outer end of said plunger, a shaft connected to said gear piece, a cam member slidably mounted on said shaft, a spring member interposed between said gear piece and said cam member, a bar pivotally mounted in said gun body and said bar having a shouldered portion engaged by the cam member, a coil spring connected to said bar, a pusher connected to said bar, a nozzle connected to the front end of said gun and said nozzle including a housing having a tapered inner recessed portion, a bayonet piercing member on said nozzle, a slidable body element engaged by said pusher, a guide pin for said body element, a rotary valve member including first, second and third ports, a detachable tip for said nozzle, a shaft member connected to said valve member and said shaft member having gear teeth thereon, a rack on said body element engaging said lastnamed gear teeth, a coil spring engaging said guide pin, a coupling detachably connecting said nozzle to said gun, and detachable holding means on the top of said gun for receiving the tapered fitting on the lower portion of the container.

Claim 3
Dependent Claim
364 words
Apparatus for dispensing a metered quantity of fluent material comprising a hollow body having a nozzle at one end, said nozzle having a dispensing opening, a selectively rotatable valve mounted in said nozzle, means for selectively rotating said valve to a first position to provide communication between said nozzle and said dispensing opening, piston means movable within said nozzle, means for advancing said piston means after said valve is moved to said first position to discharge material from said nozzle through said dispensing opening, means for rotating said valve to a second position to provide communication between said nozzle and a source of supply of material to be dispensed, means for retracting said piston after said valve is moved to said second position to create a sub-atmospheric pressure within said nozzle and to draw material thereinto from said source of supply, whereby a metered quantity of material is discharged from said nozzle when said piston means is moved in one direction, and an equal quantity of material is introduced into said nozzle when said piston means is moved in an opposite direction, an operating lever swingably mounted on said body, means operatively connected to said lever for sequentially operating said means for rotating said valve to a first position and said means for advancing said piston means and said means for rotating said piston to a second position when said lever is moved in one direction, and for operating said means for selectively retracting said piston when said lever is moved in an opposite direction, and means for advancing said piston means including gear means rotatably mounted in said hollow body and connected to said operating lever, a rod connected to said piston and said rod extending into said hollow body, a collar fixed to said rod in spaced relationship to said piston, spring means carried by said rod adjacent to said collar, a sleeve slidably mounted on the end of said rod remote from said piston, and said sleeve having a toothed rack meshing with said gear means, whereby rotation of said gear means moves said sleeve along said rod into engagement with said spring means to cause said piston to be advanced.
