Abstract
Abstract A safety razor has a handle, a head on the handle on which a razor blade or blade holder is mountable, a reservoir for water or other suitable lubricating liquid for shaving and an outlet for supplying the liquid from the reservoir to the blade, whereby the liquid is available for the skin during shaving.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
243 words
A safety razor for shaving hairs off skin having a handle, a head on the handle and reciprocally movable along an axis relative to the handle from a first outward non-dispensing position to a second inward full dispensing position, a razor blade holder mounted on the head and at least one razor blade in the razor blade holder and a non-pressurized and non-aerosol reservoir for lubricating liquid for shaving, the head having an aperture proximate to the blade holder for dispensing lubricating liquid during shaving, the reservoir forming the handle of the safety razor and the reservoir having an outlet in increasing fluid communication with the head aperture for supplying the lubricating liquid to the head when the head is urged inwardly from the first non-dispensing position progressively toward the second inward full dispensing position, the head being spring-loaded, the spring serving to bias the head outwardly along the axis relative to the handle toward the first non-dispensing position whereby no liquid is normally supplied from the reservoir to the head, the head being reciprocally movable along the axis towards the handle upon application of pressure thereto toward the second liquid dispensing position whereby lubricating liquid is increasingly dispensed from the head of the razor to the skin during shaving by gravity feed from the reservoir to the head as greater pressure is applied to the head thereby enabling lubrication of an area of skin to which the razor blade is being applied.
Claim 2
Dependent Claim
243 words
A safety razor for shaving hairs off skin having a handle, a head on the handle and reciprocally movable along an axis relative to the handle from a first outward non-dispensing position to a second inward full dispensing position, a razor blade holder mounted on the head and at least one razor blade in the razor blade holder and a non-pressurized and non-aerosol reservoir for lubricating liquid for shaving, the head having an aperture proximate to the blade holder for dispensing lubricating liquid during shaving, the reservoir forming the handle of the safety razor and the reservoir having an outlet in increasing fluid communication with the head aperture for supplying the lubricating liquid to the head when the head is urged inwardly from the first non-dispensing position progressively toward the second inward full dispensing position, the head being spring-loaded, the spring serving to bias the head outwardly along the axis relative to the handle toward the first non-dispensing position whereby no liquid is normally supplied from the reservoir to the head, the head being reciprocally movable along the axis towards the handle upon application of pressure thereto toward the second liquid dispensing position whereby lubricating liquid is increasingly dispensed from the head of the razor to the skin during shaving by gravity feed from the reservoir to the head as greater pressure is applied to the head thereby enabling lubrication of an area of skin to which the razor blade is being applied.
Claim 3
Dependent Claim
19 words
A safety razor as claimed in claim 1, wherein orientation of the at least one razor blade is reversible.
Claim 4
Dependent Claim
26 words
A safety razor as claimed in claim 1, wherein the blade holder is a sliding fit with mutually engageable parts of the head of the razor.
Claim 5
Dependent Claim
20 words
A safety razor as claimed in claim 1, wherein the blade holder is rotatable about the head of the razor.
Claim 6
Dependent Claim
13 words
A safety razor as claimed in claim 1, wherein the reservoir is squeezable.
Claim 7
Dependent Claim
19 words
A safety razor as claimed in claim 1, wherein the reservoir includes pump means for augmenting the gravity feed.
Claim 8
Dependent Claim
18 words
A safety razor as claimed in claim 1, wherein the blade holder has two pairs of contra-orientated blades.
