Claim 1
Independent Claim
318 words
A disposable shaver comprising: in combination a shaving head and a unified handle and shaving lubricant container; said shaving head including at least one razor blade operatively disposed within blade holding means; said blade holding means having a shaving surface for contact with the surface to be shaved during shaving; said razor blade disposed and maintained at a selected angle with respect to said shaving surface of said blade holding means for satisfactory shaving; said unified handle and shaving lubricant container including an elongated substantially hollow shaving lubricant container having a bore for containing the shaving lubricant, said container connected at one end thereof to said shaving head to dispose said shaving head in shaving array, said container being defined by walls thereof and having a closable opening at one end thereof; one of said shaving lubricant container walls having an exterior surface including a designated contour and containing a slot therein closed by a relatively thin and rupturable membrane; said slot disposed within and extending longitudinally on said exterior surface of said wall of said shaving lubricant container; said unified handle and shaving lubricant container further including membrane rupturing means slidably disposed within said slot and initially disposed in a first position at one end of said slot; said membrane rupturing means including shaving lubricant pushing means disposed within and substantially matching in cross-sectional shape said bore of said unified handle and shaving lubricant container; and said membrane rupturing means including manual engagement means disposed exteriorly of said exterior surface containing said slot, whereby the user may push upon and move said manual engagement means longitudinally and exteriorly with respect to said unified handle and shaving lubricant container to rupture said membrane, to transport said shaving lubricant pushing means longitudinally within said bore, to force the shaving lubricant to expel from the opposite end of said unified handle and shaving lubricant container through said closable opening therein.

Dependent Claim
318 words
A disposable shaver comprising: in combination a shaving head and a unified handle and shaving lubricant container; said shaving head including at least one razor blade operatively disposed within blade holding means; said blade holding means having a shaving surface for contact with the surface to be shaved during shaving; said razor blade disposed and maintained at a selected angle with respect to said shaving surface of said blade holding means for satisfactory shaving; said unified handle and shaving lubricant container including an elongated substantially hollow shaving lubricant container having a bore for containing the shaving lubricant, said container connected at one end thereof to said shaving head to dispose said shaving head in shaving array, said container being defined by walls thereof and having a closable opening at one end thereof; one of said shaving lubricant container walls having an exterior surface including a designated contour and containing a slot therein closed by a relatively thin and rupturable membrane; said slot disposed within and extending longitudinally on said exterior surface of said wall of said shaving lubricant container; said unified handle and shaving lubricant container further including membrane rupturing means slidably disposed within said slot and initially disposed in a first position at one end of said slot; said membrane rupturing means including shaving lubricant pushing means disposed within and substantially matching in cross-sectional shape said bore of said unified handle and shaving lubricant container; and said membrane rupturing means including manual engagement means disposed exteriorly of said exterior surface containing said slot, whereby the user may push upon and move said manual engagement means longitudinally and exteriorly with respect to said unified handle and shaving lubricant container to rupture said membrane, to transport said shaving lubricant pushing means longitudinally within said bore, to force the shaving lubricant to expel from the opposite end of said unified handle and shaving lubricant container through said closable opening therein.
Claim 3
Dependent Claim
