Definitions
- the present invention is directed to razor heads comprising flexible blades, and more particularly, to razor heads with at least two blades adapted to independently flex in response to shaving forces.
- Safety razors typically include one or two blades disposed between a guard and a cap. In many instances, each of these elements is typically rigidly fixed relative to one another and disposed in skin-engaging contact during shaving. In recent years, dynamic shaving systems have been introduced which permit one or more of the skin-engaging elements of the shaving system to move in response to forces encountered during shaving.
- a razor head in which at least two blades thereof are flexible, and more particularly, are adapted to independently flex in response to shaving forces to allow the blades to better conform to the contours of the skin surface in order to achieve greater comfort and closeness.
- a razor head in which a blade thereof is flexible and, more particularly, the center portion of the blade has a greater stiffness compared to the end portions thereof so as to provide a flatter curve along the length of the blade in response to shaving forces.
- Various embodiments of the present invention provide razor heads which comprise a plurality of flexible blades which are adapted to independently flex in response to shaving forces.
- FIG. 1 A perspective view of an embodiment of the present invention
- FIG. 1 A perspective view of an embodiment of the present invention

- FIG. 1 A perspective view of an embodiment of the present invention
- FIG. 1 A perspective view of an embodiment of the present invention
- FIG. 1 A perspective view of an embodiment of the present invention
- Still other embodiments of the present invention provide razor heads having independent flexible blades in which the blade support is provided with a skin-engaging shaving aid material.
- FIG. 1 is an exploded perspective view of one embodiment of a razor head of the present invention.
- FIG. 2 is an enlarged front elevational view of a blade element shown in FIG. 1.
- FIG. 3 is an enlarged side elevational view of a blade element taken along line 3-3 of FIG. 2.
- FIG. 4 is an enlarged cross-sectional view taken along line 4-4 of FIG. 1 in which the razor head is assembled.
- the present invention provides razor heads with blades adapted to flex during shaving in order to adapt to the contours of a curved surface being shaved so as to provide close and comfortable shaves.
- One preferred embodiment of the present invention provides razor heads with blades which are independently flexible within a generally rigid blade support.
- An embodiment also provides blades which have varying stiffs along their length.
- One embodiment of the present invention, illustrated in FIG. 1, comprises a razor head 10 generally comprising a blade support 20 and at least two, and preferably, three flexible blade elements 30 such as a leading blade element, a middle blade element, and a trailing blade element.
- the term “razor head” is meant to include cartridges adapted to be connected to a separate razor as well as the operative cutting portion of a disposable razor wherein the handle and cutting portion are formed as a single unit.
- the term “flexible” is used to indicate a bending capability of a blade along the blades longitudinal axis in response to shaving forces. As such, the flexible blade elements of the present invention differs from generally rigid blades which may deflect vertically or angularly in response to shaving forces.
- blade elements 30 comprise a generally elongate blade 40 attached to a generally corrugated flexible member 50.
- the illustrated blade 40 comprises a cutting edge 42, a central opening (not shown) and cutouts (not shown) at each end portion 44 and 46 through which interlocking projections 52 of flexible member 50 can extend for securing blade 40 to flexible member 50.
- Such a configuration is ideally suited for assembly by plastic insert molding.
- cutting edge 42 of blade 40 extends outwardly from flexible member 50, i.e., the portion of blade 40 containing cutting edge 42 is cantilevered from flexible member 50.
- flexible member 50 preferably comprises a generally sinusoidal configuration, and particularly, a generally rectangular sine wave configuration, in which portions thereof provide a generally flat top surface for supporting blade 40.
- Flexible member 50 also comprises tabs 54 and 56 which extend outwardly beyond the end portions 44 and 46 of blade 40. As explained in greater detail below, tabs 54 and 56 are movably supported in blade support 20 so that blade elements 30 can be repetitively flexed therebetween in response to shaving forces. When such shaving forces are removed, the inherent resiliency of blade element 30 is preferably sufficient to return the blade element to an original position.
- the blade elements are designed to have a varying stiffness along their length.
- a blade element having a greater stiffness in the center portion compared to the end portions to provide a flexible blade having a flatter curve in the central portion.
- the guard bar since the guard bar is generally rigid it will flatten the skin in front of the blade and a stiffer center portion will correspond more closely to the configuration of the skin, limiting the variation in blade protrusion (i.e., amount the blade edge extends from a tangent line connecting a cap and a guard) and limiting the variation in the effective shaving angle between the blade and the skin.
- blade support 20 comprises a frame 60 and a base 70.
- the illustrated frame 60 comprises a cap 62, a guard 64, and sides 66.
- cap 62, guard 64 and sides 66 are formed as a single unit, e.g., formed from an injected molded polymeric material such as polyethylene, polyvinyl chloride or combinations thereof.
- the guard can be attached or integrally formed with the base.
- the frame and the base are suitably attached to each other, e.g., by adhesives, thermal bonding or a snap-fit.
- blade elements 30 are disposed, when assembled, in a vertically spaced relation, as well as disposed in a horizontally spaced relation across the width of the blade support.
- frame 60 and base 70 cooperate to provide a generally rigid support which generally does not flex or bend as a result of shaving forces.
- the present invention translates forces on the blades into deflection while the cap and guard remain stationary.
- base 70 is provided at its ends with steps 72, and sides 66 of frame 60 are provided with corresponding slots 68 (best shown in FIG. 1) to movably hold each blade element 30 therebetween.
- This illustrated blade support arrangement permits inward movement of tabs 54 and 56 in response to shaving forces along the length of blade element 30 without disengaging the tabs from the slots.
- the blade elements are illustrated as separate, from the present description it will be appreciated by those skilled in the art that the blade elements can be attached at their end portions, e.g., the flexible elements can be molded as a unit with their end portions attached so that the blades are disposed in spaced vertical relation and spaced horizontal relationship across the width, and the molded unit can be provided with a single tab on each end which is retained in a blade support.
- the present invention eliminates the need for a separate spacer element installed between adjacent blades of unitary dynamic razor systems, e.g., shaving systems where the cap and guard, as well as the blades flex as one.
- the independently flexible blade elements of the present invention allow the blades to have a greater flexibility without compromising structural integrity.
- blade support 20 preferably comprises wash through slots for rinsing shaving debris from the spaces between the blades.
- frame 60 desirably has a rear wall 61 having openings 63
- base 70 desirably has openings 73 which, in conjunction with the openings in flexible member 50, provide passageways for rinsing shaving debris from the spaces between the blades.
- Razor head 10 of the present invention is assembled by inserting blade elements 30 sequentially in frame 60. Specifically, the rear trailing blade element is inserted first, the middle blade element is inserted next, and the leading blade element inserted last.
- the base is then attached to the frame to secure the blade elements therein.
- the base is suitably attached to a separate razor for wet shaving.
- the blade elements being similarly configured reduce the cost of the shaving system by reducing the number of different elements of the razor head, and thus, the tooling required and the cost and time required for assembly.
- the similarly configured blade elements of the present invention reduce the complexity for forming the razor head in that individual blade elements can be readily inserted in the desired slots of the blade support. Also, by increasing the number of blade edges in contact with a skin surface, shaving forces are distributed over a greater area in order to provide a more comfortable shave.
- Another preferred embodiment of the present invention comprises a razor head, as described above, in which shaving system 10 further comprises a skin-engaging shaving aid material.
- shaving aid material 80 is attached to cap 62 of blade support 20.
- shaving aid refers equally either to the active ingredient combined within a delivery system, such as a water-insoluble micro-porous matrix structure or to the active ingredient alone.
- Previously suggested active ingredients include those disclosed in U.S. Patent No. 4,170,821 to Booth, which is hereby incorporated by reference.
- a shaving aid may comprise one or various combinations of the following:
- active ingredients may include various pigments, i.e., titanium dioxide, fragrances, aloe vera, flavoring agents, mineral oils, essential oils and other oils derived from plants.
- the shaving aids of the present invention may also comprise other compounds or blends of compounds such as water-insoluble polymers such as polystyrene and polypropylene.
