Abstract

Abstract A single use disposable medical razor having an elongated handle member within which is disposed a hollow portion defining a reservoir extending from a proximate end to a distal end, closure means for the reservoir at the proximate end and a dispensing orifice at the distal end of the reservoir, plunger means transversely disposed to the hollow portion of the reservoir and essentially filling generally a first half of the reservoir adjacent the proximate end thereof and adapted to move along throughout a length of the second half of the reservoir from about a midportion of the hollow portion to a distal end thereof, the reservoir adapted for storing shaving cream in the second half thereof, a race means disposed along an element of the reservoir and extending less than the entire length of the handle from about a midpoint of the hollow portion to the proximate end thereof essentially generally along the first half, protrusion means extending from the plunger means outwardly through the race means for grasping manually by a user and, after removal of an adhesive tape from the orifice, whereby displacement of the plunger means by grasping the protrusion means and moving it along the race means moves the plunger into the second half of the reservoir for causing the shaving cream to be dispensed from the dispensing orifice in the distal end.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 352 words
A single use disposable medical razor comprising an elongated handle means within which is longitudinally disposed a hollow portion defining a reservoir having inner surfaces extending from a proximate end to a distal end therof, closure means for the reservoir at the proximate end of the reservoir, a dispensing orifice at the distal end of the reservoir, plunger means transversely disposed to the hollow portion of the reservoir and essentially filling generally a first half of the reservoir generally adjacent the proximate end thereof and adapted to move along throughout a length of the second half of the reservoir from about a midportion of the hollow portion to a distal end thereof, the reservoir adapted for storing shaving cream in the second half thereof, the plunger having a projecting face for contacting the shaving cream in the second half of the reservoir, a race means disposed along an element of the reservoir and extending less than the entire length of the handle from about a midpoint of the hollow portion to the proximate end thereof essentially generally along the first half, protrusion means extending from the plunger means outwardly through the race means for grasping manually by a user and whereby displacement of the plunger means is by grasping the protrusion means and moving it along the race means and by moving the plunger means into the second half of the reservoir for causing the shaving cream to be dispensed from the dispensing orifice in the distal end, adhesive tape means closing off the dispensing orificce, an inclined land molded on one of the inner surfaces of the reservoir at the midportion of the reservoir for locking the plunger against reverse movement after the projecting face overrides the inclined land, thus preventing removal of the plunger from the reservoirs and a second inclined land molded on said one inner surface of the reservoir at the furthest point of travel of the projecting face adjacent the dispensing orifice for locking the plunger against reverse movement after the projecting face overrides the second inclined land, thus preventing refilling of the reservoir through the orifice.
Claim 2
Dependent Claim 352 words
A single use disposable medical razor comprising an elongated handle means within which is longitudinally disposed a hollow portion defining a reservoir having inner surfaces extending from a proximate end to a distal end therof, closure means for the reservoir at the proximate end of the reservoir, a dispensing orifice at the distal end of the reservoir, plunger means transversely disposed to the hollow portion of the reservoir and essentially filling generally a first half of the reservoir generally adjacent the proximate end thereof and adapted to move along throughout a length of the second half of the reservoir from about a midportion of the hollow portion to a distal end thereof, the reservoir adapted for storing shaving cream in the second half thereof, the plunger having a projecting face for contacting the shaving cream in the second half of the reservoir, a race means disposed along an element of the reservoir and extending less than the entire length of the handle from about a midpoint of the hollow portion to the proximate end thereof essentially generally along the first half, protrusion means extending from the plunger means outwardly through the race means for grasping manually by a user and whereby displacement of the plunger means is by grasping the protrusion means and moving it along the race means and by moving the plunger means into the second half of the reservoir for causing the shaving cream to be dispensed from the dispensing orifice in the distal end, adhesive tape means closing off the dispensing orificce, an inclined land molded on one of the inner surfaces of the reservoir at the midportion of the reservoir for locking the plunger against reverse movement after the projecting face overrides the inclined land, thus preventing removal of the plunger from the reservoirs and a second inclined land molded on said one inner surface of the reservoir at the furthest point of travel of the projecting face adjacent the dispensing orifice for locking the plunger against reverse movement after the projecting face overrides the second inclined land, thus preventing refilling of the reservoir through the orifice.
Claim 3
Dependent Claim 16 words
The apparatus of claim 1 wherein the dispensing orifice is disposed centrally within the distal end.
Claim 4
Dependent Claim 16 words
The apparatus of claim 1 wherein the the razor is securably affixed at the proximate end.
Claim 5
Dependent Claim 15 words
The apparatus of claim 1 wherein the razor is formed integrally with a blade means.
Claim 6
Dependent Claim 29 words
The apparatus of claim 1 wherein the shaving cream contains a biocidal material wherein the biocidal material is a material selected from the group of fungicides, viricides and bactericides.
Claim 7
Dependent Claim 31 words
The apparatus of claim 1 wherein the plunger means engages a positive stop means adjacent the distal end of the reservoir for tending to prevent the plunger means from being retractable.
