Definitions
- Oldrovd et al.. U.S. Patent No. 4,063,354, discloses a shaving unit wherein a blade unit comprises two blades separated by a spacer 5 (Figs. 13-16) .
- a resiliently flexible metallic or plastic guard 3 is secured to the blade unit by spot welding or other means (col. 3, lines 26-28).
- the blade unit which is illustrated in its normal forward position of maximum blade exposure in Fig. 13, can bow rearwardly under pressure applied during shaving to carry the blade unit along a plane to the rear, relative to the platform 1 and cap 4. This reduces blade exposure but increases the shaving angle, as indicated by dotted lines 3' in Figs. 13 and 15 (col. 3, lines 26-37) .
- Althauset et al.. U.S. Patent No.
- the present invention provides a novel means of applying a friction reduction agent to a substantial portion of the blade cartridge so as to improve shaving comfort, while minimizing manufacturing costs associated with incorporating the friction reducing agent in the blade cartridge.
- Figure 6 illustrates a front view of a first embodiment of the cap member of the present invention.
- Figure 7 illustrates an end view of the cap member shown in Fig. 6.
- Figure 10 illustrates one embodiment of the platform member adapted to receive a razor handle so as to pivotally connect the blade cartridge to the razor handle.
- Figure 13 illustrates a side view of an end clip.
- Figs. 1-14 illustrate a movable blade shaving cartridge ("MBSC" or blade cartridge) or razor head 10 which comprises a platform member 2, flexible blade means 32, 34, a spacer 6 and a cap member 8.
- MBSC movable blade shaving cartridge
- the blade seat 24 further comprises an upper surface 28, as well as a plurality of securing apertures 30.
- the securing apertures operate in conjunction with fastening means 80 located on the cap member 8, such as rivets, to permanently secure the platform member 2, the flexible blade means, the spacer 6 and the cap member 8 together.
- the primary blade 32 and the secondary blade 34 are separated from each other by a distance of about 0.020 inches to about 0.050 inches by the spacer 6.
- the height of the rear portion 64 of spacer 6 defines the separation between the two blades 32,34.
- the secondary blade 34 is disposed on the upper surface 58 of the spacer 6 with the cutting edge extending over the opening 47 created between the forward portion 62 of the spacer 6 and the lower surface 52 of the secondary blade 34. Similar to the primary blade 32, the width of the rear portion 64 of the spacer 6 is such that a substantial portion of the secondary blade 34 extends over the opening 47.
- the cap member 8 is disposed on the upper surface 54 of the secondary blade 34 such that one edge of the cavity 76 formed on the lower surface 72 of the cap member 8 generally aligns with beginning of the forward portion 62 of the spacer 6 so as to form a vertical plane.
- the skin engaging portion 88 of the spacer 6 functions to maintain the geometry of the primary blade 32 relative to the shaving surface by establishing a safe contact and control surface behind the primary blade 32.
- the skin engaging portion 88 of the spacer 6 also maintains the geometry of the secondary blade 34 relative to the shaving surface.
- the height of the lips 60 formed of the support members 22 may be varied so as to effect different bending patterns.
- each blade 32,34 may be tapered such that the thickness of the blade decreases in the direction of the forward portion of the blade.
- each blade 32,34 can comprise a U-shaped channel in the forward portion of the blades, which functions to define the flexing zone for the blade 32,34.
- the blade cartridge 10 to detachably connect the blade cartridge 10 to a handle, such as in U.S. Patent No. 4,026,016 entitled RAZOR BLADE ASSEMBLY, issued to Warren I. Nissen, which is incorporated herein by reference.
- the upper and lower surfaces 58,56 of the rear portion 64 of the spacer 6 comprises a plurality of channels so as to allow shaving debris to be led out the back of the blade cartridge 10.
- water can be directed into the back of the blade cartridge 10 to be channeled out through the front of the blade cartridge 10 and the edges 36,38 of the blades 32,34.
- end clips coated with a friction reduction agent provide for a significant reduction in the drag forces associated with the shaving process so as to provide a more comfortable shave.

Abstract
Tête (10) à lames mobiles comprenant un élément plate-forme (2) pourvu d'un siège (24) de lame et d'un élément (20) de protection, lequel est placé en avant de la parallèle du siège (24) de lame de manière à former une fente (26) longitudinale entre lui-même et le siège. Une première lame (32) est disposée sur ledit siège (24) de façon à ce que son bord coupant soit situé en arrière de l'élément de protection. Une portion importante de cette première lame (32) s'étend dans la fente formée entre l'élément de protection et le siège de la lame afin que celle-ci soit flexible dans la fente. Un dispositif d'écartement (6) est placé sur la surface supérieure de la première lame et il comprend une portion arrière de même qu'une portion avant s'étendant à partir de la portion arrière, sa fonction étant d'empêcher un déplacement vers le haut de la première lame (32).
