초록 ▼

An aerosol type dispenser, wherein a dispensable fluid product is in storage, under pressure, intermediate wall surfaces of the dispenser and exterior surfaces of a pliable, impervious, expandable sac. Propellant gas, contained in isolation within the confinements of the sac, influence expansible surfaces of the sac to exert an expulsion force to the product. A dispensing valve mechanism, of choice, is utilized for the appropriate dispensing application. Propellant vapors may be co-dispensed with the product to provide an atomized spray or the vapors can be used to remove product residue from the valve mechanism.

대표청구항 ▼

A portable self-contained pressurized aerosol type dispenser comprising a rigid walled closed buttom container including a top closure having an outwardly curled annular opening; a dispensing valve mechanism having at least a retaining cup secured in closing relation with the curled annular opening; a valve body having shut-off components housed therein and product inlet passage; an outwardly protruding movable discharge nozzle in communication with the shut-off components; a dip tube having an open end depending from the valve body in communication with the inlet passage for delivery of a fluid product therethrough from the container; a pliable impervious sac within the container adapted to expand to the internal extremities of the container, and having an annular open end secured in sealing engagement with the valve mechanism; said container adapted to store a dispensible product, under pressure, intermediate the container and exterior surfaces of the sac; said sac adapted to receive and confine therein a propellant gas that acts upon internal surfaces of the sac expanding the sac thereby exerting an expulsion force upon the product; the open end of the dip tube extending through and sealed relative to the sac, providing an enclosed passageway within the sac for the conveyance of the product therethrough; the valve mechanism being in communication with the interior of said container through said dip tube for dispensing said product from said container and into said dip tube and valve mechanism; the valve mechanism having limited communication with the interior of the sac for releasing propellant vapors as well as said product through said nozzle.
