Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
136 words
A liquid dispensing device which comprises: a. a hollow handle having a sealed proximal end and a distal end and containing a liquid; b. a nozzle mounted on the distal end of said handle and in fluid communication with the interior of said handle, the distal end of said nozzle being sealed, said nozzle including a stress raiser adjacent the sealed end thereof, said stress raiser being defined by a stress concentrating discontinuity in the cross section of said nozzle; c. a web secured to said device and extending distally from the point of securement, said web having a substantial planar area for bearing against the interior surface of a sponge mounted thereon; d. a sponge disposed upon and substantially surrounding said nozzle and said web; and e. means for maintaining said sponge on said web.
