Abstract
Abstract A liquid dispenser embodying a plastic canister with a fill inlet at one end and an outlet spout at the other end insertable within a cylindrical plastic valve body formed with a bracket thereon for removable wall mounting. A decorated plastic cover is removably attached to the front of and conceals the canister when wall mounted. The valve body includes a metal ball valve and a finger operable valve actuator pivoted in the valve body and provided with a magnet at its inner lower end for pivotal movement into engagement with the valve body to attract and move the ball valve relative to the outlet spout opening so that the contents may be dispensed therethrough.

Claim 1
Independent Claim
141 words
In a dispenser, a canister having a lower discharge spout, a cylindrical valve body including a valve chamber therein for vertically receiving said spout, a reduced discharge bore extending below said chamber, a valve seat at the upper end of said discharge bore, a metal ball valve and attaching means for coupling the valve body to said canister, a recess in said valve body with a magnetic disc pivotally arranged therein, a cover for enclosing said canister and valve body, a lever pivoted to said cover and having finger engaging means thereon at its upper end, an inturned lower end on said lever underlying said disc, whereby when said lever is depressed and pivoted said disc will be tilted upwardly into engagement with said valve body to magnetically attract and displace said ball from its seat and discharge canister contents therethrough.
