  • Patent number: 4784652
    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.
