Abstract

Abstract A disposable shaver includes a primary plunger structure in the pre-rotated position and in the post-rotated position. The disposable shaver comprises: the primary plunger structure; and a handle-shaver head structure. The primary plunger structure further comprises: a plurality of longitudinally directed ribs; and a transversely directed disc structure. The disc structure includes a middle circular disc being a layer of styptic material. The handle-shaver head structure further comprises: a rotatable member; a handle member; a primary plunger holder; and a shaver head. The shaver head includes a rear conduit opening. The primary plunger structure is rotatable about a transverse axis defined by the flexible extension of the rotatable member in order to be inserted into such handle member. The primary plunger structure further comprises a primary plunger end which includes upper piercing means. The handle-shaver head structure further comprises a secondary plunger which is fully retracted within the handle member when in the pre-packaged position and which is fully inserted within the handle member after full discharge of the pre-enclosed shaving gel. The handle member includes a conduit which leads to the shaver head conduit opening.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 233 words
A disposable shaver comprising: a. a primary plunger structure and a handle-shaver head structure; b. said handle-shaver head structure further comprising: a rotatable member including a flexible extension; a hollow handle member including pre-enclosed shaving gel and including a conduit; a primary plunger holder; and a shaver head including a rear conduit opening which is continuous with said hollow handle member conduit; c. said primary plunger structure being initially in a pre-rotated position and being positionable in a post-rotated position, said primary plunger structure being rotatable about a transverse axis being defined by said rotatable member flexible extension such that said primary plunger structure is insertable within said hollow handle member; d. said handle-shaver head structure further comprising a secondary plunger; e. said secondary plunger being fully retracted within said hollow handle member when in the pre-packaged position and being fully inserted within said hollow handle member after full discharge of said pre-enclosed shaving gel; f. said secondary plunger being fully inserted within said hollow handle member when said primary plunger is fully inserted within said hollow handle member and wherein said secondary plunger being fully retracted within said hollow handle member when said primary plunger is outside said hollow handle member; and g. said primary plunger structure being pre-packaged external to said handle-shaver head structure and said secondary plunger structure being pre-packaged in the fully retracted position within said hollow handle member.
Claim 2
Dependent Claim 233 words
A disposable shaver comprising: a. a primary plunger structure and a handle-shaver head structure; b. said handle-shaver head structure further comprising: a rotatable member including a flexible extension; a hollow handle member including pre-enclosed shaving gel and including a conduit; a primary plunger holder; and a shaver head including a rear conduit opening which is continuous with said hollow handle member conduit; c. said primary plunger structure being initially in a pre-rotated position and being positionable in a post-rotated position, said primary plunger structure being rotatable about a transverse axis being defined by said rotatable member flexible extension such that said primary plunger structure is insertable within said hollow handle member; d. said handle-shaver head structure further comprising a secondary plunger; e. said secondary plunger being fully retracted within said hollow handle member when in the pre-packaged position and being fully inserted within said hollow handle member after full discharge of said pre-enclosed shaving gel; f. said secondary plunger being fully inserted within said hollow handle member when said primary plunger is fully inserted within said hollow handle member and wherein said secondary plunger being fully retracted within said hollow handle member when said primary plunger is outside said hollow handle member; and g. said primary plunger structure being pre-packaged external to said handle-shaver head structure and said secondary plunger structure being pre-packaged in the fully retracted position within said hollow handle member.
Claim 3
Dependent Claim 28 words
