Eyewash dispenser
First Claim
1. A portable, hand-held eyewash dispenser for discharging an eyewash liquid, the eyewash dispenser comprising:
- a housing having a wall inner surface and being configured to permit the user to comfortably grasp and hold the same in one hand;
an expandable bladder having an outer surface and disposed in the interior of said housing;
said inner and outer surfaces conjointly defining a reservoir chamber therebetween for holding the eyewash liquid;
a propellant cartridge containing a propellant fluid under pressure;
a holder mounted within said bladder for holding said propellant cartridge therein;
nozzle means communicating with said reservoir chamber for guiding the eyewash liquid to the outside;
manually-actuated release means mounted on said housing for penetrating said cartridge to release said propellant fluid;
passage means interconnecting said cartridge and said bladder for conducting the released fluid into the interior of said bladder for filling and expanding the latter thereby placing the eyewash liquid under a predetermined pressure; and
,pressure valve means, mounted in said nozzle means, responsive to said predetermined pressure of said eyewash liquid for releasing the same to the outside.

Abstract
The invention relates to a portable, handheld eyewash dispenser for discharging an eyewash liquid. The eyewash dispenser includes a housing and an expandable rubber bladder mounted in the housing. The housing and the rubber bladder conjointly define a chamber for accommodating the eyewash liquid therein. A propellant cartridge containing a propellant under pressure is mounted in the rubber bladder. A pressure valve responsive to a predetermined pressure of the eyewash liquid is mounted in the housing. A release mechanism is provided for acting on the propellant cartridge for discharging the propellant therefrom to inflate and expand the bladder thereby imparting pressure to the eyewash liquid causing the latter to be expressed through a nozzle. The housing is configured to permit the user to comfortably grasp the dispenser in one hand. The user can swing the eyewash dispenser with the hand so as to strike the release mechansim against a hard surface thereby actuating the latter and causing the eyewash liquid to be expressed through the nozzle.

3. A portable, hand-held eyewash dispenser for discharging an eyewash liquid under the pressure of a fluid propellant contained in a propellant cartridge, the eyewash dispenser comprising:
-
a housing having a wall inner surface and being configured to permit the user to comfortably grasp and hold the same in one hand; an expandable bladder having an outer surface and disposed in the interior of said housing; said inner and outer surfaces conjointly defining a reservoir chamber therebetween for holding the eyewash liquid; a holder mounted within said bladder and having an interior adapted to accommodate the propellant cartridge therein; nozzle means communicating with said reservoir chamber for guiding the eyewash liquid to the outside; manually-actuated release means mounted on said housing for penetrating the cartridge to release said propellant fluid; passage means extending between said interior of said holder and said bladder for conducting the released fluid into the interior of said bladder for filling and expanding the latter thereby placing the eyewash liquid under a predetermined pressure; and
,pressure valve means, mounted in said nozzle means, responsive to said predetermined pressure of said eyewash liquid for releasing the same to the outside.
