Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
195 words
A liquid dispenser, comprising: a. a liquid reservoir; b. a reciprocal hand operated pump mounted on said reservoir for the discharge of liquid from the reservoir; c. an inlet tube for supplying liquid to said hand operator, said inlet tube extending to the bottom of said reservoir; d. a squeeze tube of larger diameter than said inlet tube continuing therefrom; e. an inlet valve at the extremity of said squeeze tube; f. a tubular housing for said squeeze tube within said reservoir, said housing having an integral constricted end to receive and compress one end of said squeeze tube and a plug in its other end to compress the other end of said squeeze tube, the ends of said squeeze tube being compressed into sealing engagement with said inlet tube and said inlet valve; g. said housing having a side fitting projecting from said housing through a wall of the reservoir and having a bore confronting said squeeze tube; h. a reciprocal means for squeezing said squeeze tube mounted in said bore; and i. foot operator means for activating said reciprocal means to provide a foot-operated pump for the discharge of liquid from the reservoir.
Claim 2
Dependent Claim
195 words
A liquid dispenser, comprising: a. a liquid reservoir; b. a reciprocal hand operated pump mounted on said reservoir for the discharge of liquid from the reservoir; c. an inlet tube for supplying liquid to said hand operator, said inlet tube extending to the bottom of said reservoir; d. a squeeze tube of larger diameter than said inlet tube continuing therefrom; e. an inlet valve at the extremity of said squeeze tube; f. a tubular housing for said squeeze tube within said reservoir, said housing having an integral constricted end to receive and compress one end of said squeeze tube and a plug in its other end to compress the other end of said squeeze tube, the ends of said squeeze tube being compressed into sealing engagement with said inlet tube and said inlet valve; g. said housing having a side fitting projecting from said housing through a wall of the reservoir and having a bore confronting said squeeze tube; h. a reciprocal means for squeezing said squeeze tube mounted in said bore; and i. foot operator means for activating said reciprocal means to provide a foot-operated pump for the discharge of liquid from the reservoir.
Claim 3
Dependent Claim
54 words
A liquid dispenser, as defined in claim 1, wherein said foot operator comprises: a. a baseplate; b. an arched leaf spring mounted on said baseplate and including a free end reciprocal when the arched leaf spring is foot depressed; and c. a thrust rod operatively connecting said spring and said reciprocal tube squeezing means.
Claim 4
Dependent Claim
100 words
A liquid dispenser, as defined in claim 1, wherein said foot operator comprises: a. a baseplate; b. an arched leaf spring hinged at one end to said baseplate and having a free end reciprocal on said baseplate; c. a flexible cover for said leaf spring arched in conformity thereto, said cover and spring being foot depressible to reciprocate the free end of said spring; d. a guide sleeve extending from said baseplate to the side fitting of said squeeze tube housing; and e. a thrust rod slidable in said sleeve and secured to said spring and to said reciprocal means.
