Definitions
- FIG. 1 is a diagrammatic representation of FIG.
- SAFETY RAZORS In the usual types of safety razor the blade only is discarded after use, the remainder of the razor being kept for use with other blades.
- Safety razors are, however, known in which the blade is permanently secured in molded plastics material shaped to leave the cutting edge of the blade exposed and to form a guard in front of the cutting edge and a cap behind the cutting edge. The head thus formed is permanently or detachably secured to a handle and the complete head is discarded when the blade reaches the end of its useful life.
- the present invention provides an improved form of such a disposable safety razor head and is characterized by the facts thatthe blade is of a kind having two opposite edges sharpened; the plastics material applied to each face of the blade is shaped to form a guard for one of the cutting edges and a cap for the other cutting edge, so that the cutting edges are exposed on opposite faces of the head; and that the head is provided with means for detachably and reversibly securing it to a handle, one cutting edge only of the blade being accessible for use in each position of attachment.
- FIG. 1 is an exploded view of one form of razor embodying the invention, the separated parts being shown in perspective;
- FIG. 2 is a side view of the assembled razor
- FIG. 3 is a plan view of the razor
- FIG. 4 is an exploded view of a second form of razor embodying the invention.
- FIG. 5 is a side view of the razor of FIG. 4 in assembled condition
- FIGS. 6 and 7 are detail, somewhat diagrammatic, views of parts of the razor of FIGS. 4 and 5;
- FIG. 8 is an exploded view of a third form of disposable safety razor head in accordance with the invention.
- FIG. 9 is a perspective view showing the head of FIG. 8 in assembled condition and a cooperating handle in condition for receiving the head;
- FIG. 10 is a part sectional side view showing the head and handle of FIGS. 8 and 9 in fully assembled condition.
- FIG. 11 is a perspective view of a fourth form of razor embodying the invention.
- the head comprises two identical moldings l of plastics material, disposed respectively above and below a double-edged safety razor blade 2 of well-known type.
- Each of the moldings l is shaped adjacent one longitudinal edge 11 to provide a guard adapted to engage the face ahead of one of the cutting edges 21 of the blade and is shaped adjacent the opposite longitudinal edge 12 to provide a cap adapted to follow the cutting edge over the face.
- One face of each member 1 is formed with projections 13 and recesses 14, while the opposite face is formed with a transversely extending groove 15, having undercut, convergent sidewalls, adapted to make locking engagement with a dovetail projection 31 on the upper end of a handle 3, which may be made of any suitable material.
- the two members 1 are assembled to the blade reversed in position relative to one another, so that the projections 13 of each member are opposite the recesses 14 of the other member and the guard edge 11 of each member is adjacent the cap edge 12 of the other member.
- the blade 2 is clamped between the two members 1 and is accurately located relative to them by the projections 13, each cutting edge 21 of the blade projecting between the guard 1 1 of one member and the cap 12 of the other member.
- the two members 1, with the blade clamped between them, are secured together, so that the blade is secured permanently in position.
- the razor head thus formed is mounted on the handle 3 by sliding the projection 31 into one of the recesses 15, to form the assembly shown in FIGS. 2 and 3.
- the members 1 may be made of thermoplastic material and they can then be secured together by heat sealing, by ultrasonic welding or by solvent welding, or they may be formed with interengaging projections and-recesses which will snap into interlocking connection when pressed together.
- the members 1 may be made of a thermosetting plastic and they may then be secured together by adhesive, or by solvent welding, or by a mechanical snap connection.
- the disposable head again comprises two identical moldings 16 of plastics material, which are secured together with a double-edged blade 2 between them.
- the members 16 have their longitudinal edge portions 11, 12 shaped to form guards and caps and are provided with interengaging projections and recesses 13, 14, all as described with reference to FIGS. 1 to 3.
- the groove 15 is omitted and each member 16 is formed with an aperture 17, approximately T-shaped in plan, the longer portions of the two apertures being in register with one another and with the central slot in blade 2.
- the handle 3 in this comprises two plastics moldings 32, 33 which are secured together around a locking device.
- This device comprises a sheet metal body 34, two levers 35 pivotally connected at 36 (see FIGS.
- a tongue 38 projecting from the body 34, enters the shorter portion or stem of the aperture 16 in the lower member 16, this arrangement preventing incorrect assembly with the head turned round in its own plane.
- Slide 37 is then moved to the FIG. 6 position, thus locking the head in position.
- the projection 37a may be constituted by a leaf spring of inverted U-form so that it will maintain a locking pressure on the levers 35.
- the portions of the blade 22 adjacent the cutting edges 21 are bent in opposite directions along lines parallel to the cutting edges, so that the blade is of Z-shape. If the blade is made of a suitable grade of stainless steel, such bending can be effected as a final manufacturing operation, after the blade has been otherwise finished. As before, the blade is secured between two identical plastic moldings 18, having interfitting projections and recesses l3, l4 and edge portions l1, l2 shaped to form a guard and a cap for the blade edge, as previously described.
- the handle 3 for use with this form of disposable head has at one end of its stem a hoodlike portion 39, which presents internally a surface against which one face of the disposable head can be engaged and clamped.
- a jaw 41 Slidably mounted in the handle under the control of a spring 40 is a jaw 41, adapted to engage the opposite face of the head and secure it against the clamping surface provided by hood 39. It will be observed that the bending of the blade allows a considerable reduction in the overall width of the head when in position for shaving, which has the advantage of allowing more clearance when shaving the more inaccessible parts of the face, such as under the nose. It will also be observed that the hood 39 serves to enclose and v protect that cutting edge of the blade which is not accessible f r ussii s -g ln" the construction 'sho wn in FIG. 11, the disposable head is withdraw thepins from the holes'and allow the head to be 7 changed. when the jaws are inthe position shown, the head can'be rotated'about the axis formed-by the pinsand extend-,
