Abstract
A dispenser device for use in dispensing liquid contents in a pressurized state from a container, compressed air obtained by pushing a dispenser head being utilized as a propellant for the liquid contents. In this dispenser device, the compressed air used as a propellant is adapted to act upon the liquid contents without contacting the liquid thereby protecting the liquid contents from air contamination, quality deterioration and the like. Moreover, this dispenser device has a simple construction and since it contains no propellant it is non-explosive.
Claims4
An isolation type dispenser device comprising, in combination, a container having a cylinder therein and including a bottom member;
- an isolation member airtightly and slidably mounted within the cylinder and dividing the cylinder into a contents storage chamber and a propellant chamber;
- a piston rod slidable into the container, the piston rod having an axial passage and an orifice opening transversely therefrom, a dispenser head communicating with the passage and mounted on said piston rod;
- a spring within the container urging the piston rod upwardly;
- a pressure propellant generating means for creating compressed air by the descent of the dispenser head and the piston rod;
- a passage between the generating means and the propellant chamber within the cylinder for conducting compressed air thereto to act upon the isolation member;
- and a further passage between the contents storing chamber and the axial passage in said piston rod, whereby the contents in said contents storage chamber are forced under the pressure created by the generating means through the axial passage and the dispenser head to be dispensed.
