Abstract

Abstract A shield overlies a razor head having a lubrication strip disposed behind the cutting edges of the blades disposed on the head. The shield is spaced from the head to facilitate drying the strip and hence reduce swelling or enlargement of the lubrication strip due to moisture absorption following shaving. The shield also has a plurality of openings through its base to facilitate circulation of air in the space between the shield and the head whereby drying of the lubrication strip and, hence, reduction of its enlargement are further accomplished.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 229 words
A razor comprising: a handle; an elongated razor head carried by said handle; a razor blade carried by said head and having a longitudinally extending cutting edge; an elongated lubrication strip on said razor head adjacent said cutting edge for lubricating the skin during shaving; an elongated shield removably carried by said head for overlying said cutting edge and said lubrication strip when said razor is not in use; means for releasably securing said shield and said head one to the other; said shield being generally channel-shaped in cross-section transverse to the longitudinal extent of said shield and having an elongated base, a pair of depending flanges along opposite sides of said base and open opposite ends, said base lying in direct overlying opposition to and being spaced from said lubrication strip to define an air space between said strip and said base when said shield is secured to said razor head, said base having a recess formed along its underside defining at least in part said air space between said lubrication strip and said shield; and means for communicating air into said space into contact with said lubrication strip to facilitate drying of the lubrication strip after shaving and return of said shield to its secured position on said head, said communicating means including at least one aperture opening through said base and communicating with said air space.
Claim 2
Dependent Claim 229 words
A razor comprising: a handle; an elongated razor head carried by said handle; a razor blade carried by said head and having a longitudinally extending cutting edge; an elongated lubrication strip on said razor head adjacent said cutting edge for lubricating the skin during shaving; an elongated shield removably carried by said head for overlying said cutting edge and said lubrication strip when said razor is not in use; means for releasably securing said shield and said head one to the other; said shield being generally channel-shaped in cross-section transverse to the longitudinal extent of said shield and having an elongated base, a pair of depending flanges along opposite sides of said base and open opposite ends, said base lying in direct overlying opposition to and being spaced from said lubrication strip to define an air space between said strip and said base when said shield is secured to said razor head, said base having a recess formed along its underside defining at least in part said air space between said lubrication strip and said shield; and means for communicating air into said space into contact with said lubrication strip to facilitate drying of the lubrication strip after shaving and return of said shield to its secured position on said head, said communicating means including at least one aperture opening through said base and communicating with said air space.
Claim 3
Dependent Claim 23 words
A razor according to claim 1 including a plurality of apertures in said shield spaced one from the other longitudinally along said shield.
Claim 4
Dependent Claim 15 words
A razor according to claim 2 wherein said plurality of apertures open into said recess.
Claim 5
Dependent Claim 27 words
A razor according to claim 1 wherein said base includes a plurality of apertures therethrough spaced longitudinally one from the other for communicating air into said space.
Claim 6
Dependent Claim 27 words
A razor according to claim 4 wherein said flanges and opposite side edges of said head have means cooperable for releasably securing said shield on said head.
Claim 7
Dependent Claim 72 words
A razor according to claim 1 wherein said base includes a plurality of apertures opening into said recess and spaced longitudinally one from the other for communicating air into said space, said flanges and opposite side edges of said head having means cooperable for releasably securing said shield on said head, said base having a pair of end ribs for engaging said razor head to space said base from said lubrication strip.
