Patent number: 5456009Abstract: Shaving systems having a plurality of cutting edges. At least one fencing element is disposed proximate one cutting edge to prevent a plurality of discrete portions of that first cutting edge from contacting the skin surface being shaved. The other cutting edge is provided with a substantially continuously unobstructed cutting edge. The present invention provides a razor head design permitting skin flow characteristics of shaving to be altered by the fenced blade to affect safety in shaving while the substantially continuously unobstructed cutting edge is exposed to deliver a closeness not obtainable with a totally fenced shaving system.Type: GrantFiled: August 23, 1994Date of Patent: October 10, 1995Assignee: Warner-Lambert CompanyInventor: Fred C. Wexler

Patent number: 5394777Abstract: A thermally enhanced shaving device is provided including a hot air supply, a blade, a housing on which the blade is mounted, and an elongated handle to which the housing is attached. The housing has a continuous hot air passageway through it which has an exit and an entrance. The blade is mounted across the exit of the passageway, while the handle has an internal channel which is connected to the entrance of the hot air passageway. The hot air supply includes a heating filament and fan which can be positioned either within the channel or remote thereto. In any case, the hot air supply, the channel, and the air passageway are all in fluid communication with one another. The device is operated by blowing ambient air across the hot filament using the fan such that the channel directs the resulting hot air through the passageway, past the blade, and onto the surface to be shaven immediately ahead of the blade's shaving path.Type: GrantFiled: September 26, 1991Date of Patent: March 7, 1995Assignee: Warner-Lambert CompanyInventor: Stanislaw D. Kozikowski

Patent number: 5369885Abstract: A wet-shaving razor unit having at least one vertically-displaceable blade responsive to forces encountered during shaving. The razor unit also includes laterally-disposed vertical return springs extending from and continuous with both ends of the razor unit for supporting the blade. The return springs allow vertical displacement of the blade in response to forces encountered during shaving and return the blade to a resting position in the absence of such forces.Type: GrantFiled: May 2, 1994Date of Patent: December 6, 1994Assignee: Warner-Lambert CompanyInventor: Frank A. Ferraro

Patent number: 5333383Abstract: A razor handle for movably supporting a flexible, wet-shaving razor unit. The handle includes a cartridge support, operable between a normal position and an advanced position, for providing support to the center of the razor unit during shaving. In the normal position, the razor unit is oriented in a substantially linear configuration, while in the advanced position, the cartridge support is advanced outwards from the housing of the handle mechanism such that the razor unit is oriented in a substantially convex configuration to enhance the shaving of concave body surfaces.Type: GrantFiled: November 30, 1992Date of Patent: August 2, 1994Assignee: Warner-Lambert CompanyInventor: Frank A. Ferraro
-
Patent number: 5329700Abstract: A flexible, twin-blade wet-shaving razor unit employing at least one embossed blade for providing improved cutting effectiveness. The embossment increases the rigidity of the blade(s), which, in turn, decreases the amplitude of any vibration introduced into the blades.Type: GrantFiled: April 29, 1993Date of Patent: July 19, 1994Assignee: Warner-Lambert CompanyInventors: Frank A. Ferraro, Vincent C. Motta

Patent number: 5324483Abstract: An apparatus and method which provides a suitable location for multiple, simultaneous synthesis of compounds. The apparatus consists of: a reservoir block having a plurality of wells; a plurality of reaction tubes, usually gas dispersion tubes, having filters on their lower ends; a holder block, having a plurality of apertures; and a manifold, which may have ports to allow introduction/maintenance of a controlled environment. The manifold top wall has apertures and a detachable plate with identical apertures. The apparatus is constructed from materials which will accommodate heating, cooling, agitation, or corrosive reagents. Gaskets are placed between the components. Rods or clamps are provided for fastening the components together. Apparatus operation involves placing the filters on the lower ends of the reaction tubes in the reservoir block wells, and the upper ends passing through the holder block apertures and into the manifold.Type: GrantFiled: February 2, 1993Date of Patent: June 28, 1994Assignee: Warner-Lambert CompanyInventors: Donna R. Cody, Sheila H. H. DeWitt, John C. Hodges, John S. Kiely, Walter H. Moos, Michael R. Pavia, Bruce D. Roth, Mel C. Schroeder, Charles J. Stankovic

Patent number: 5318429Abstract: The present invention is a wet-shaving unit and a process for making same by injection molding. Additionally, the present invention provides an apparatus for molding the wet-shaving razor unit. The present invention is adaptable for addition to conventional razor blade manufacturing methods and existing manufacturing apparatus and facilities. Moreover, the present process results in a product which significantly reduces or eliminates entirely undesirable blade distortion and vibration.Type: GrantFiled: February 28, 1992Date of Patent: June 7, 1994Assignee: Warner-Lambert CompanyInventors: C. Edward Butlin, deceased, Edward S. Butlin, William T. Conrad, Jr.

Patent number: 5313706Abstract: The present invention is directed to a razor head having at least one blade with a sharpened edge disposed between a guard member and a cap member. The blade is supported in a manner such that the blade is pivotable about a point directly below, or below and forwardly of, the sharpened edge of the blade. The pivoting blade arrangement of the present invention is particularly adapted to decrease the blade exposure while increasing the guard-blade span and the shaving angle when the blade is subjected to forces during shaving. Biasing members are also provided for returning the blade edges to their original position when shaving forces are not acting on the razor head. While the razor head of the present invention is illustrated in a preferred embodiment as a two blade disposable cartridge, alternative embodiments including a single blade and a completely disposable razor are within the scope of the present invention.Type: GrantFiled: October 5, 1992Date of Patent: May 24, 1994Assignee: Warner-Lambert CompanyInventors: Vincent C. Motta, Frank A. Ferraro

Patent number: 5313705Abstract: A segmented guard bar and skin flow control members disposed in the spaces between the guard bar segments. Though not limited to any specific type of razor, the present invention is particularly suited for use with a flexible safety razor having a cap member at least one and preferably two blades separated by a spacer, and a blade seat having a plurality of blade support portions separated by corrugations and a segmented guard bar with each segment independently connected to the blade support portions. Skin flow control members having at least one groove join the adjacent guard bar segments.Type: GrantFiled: February 1, 1993Date of Patent: May 24, 1994Assignee: Warner-Lambert CompanyInventors: David F. Rivers, Frank A. Ferraro
-
Patent number: 5301425Abstract: A rotary powered dynamic shaving system providing multidirectional cutting during shaving. The shaving system includes a disposable head rotatably connected to a handle. This head contains a plurality of blades. Each of the blades is displaceably positioned in the head, thereby providing a degree of "float" to the blade and, in turn, substantially reducing the propensity of the device to nick the skin during shaving.Type: GrantFiled: November 4, 1992Date of Patent: April 12, 1994Assignee: Warner-Lambert CompanyInventor: Frank A. Ferraro

Patent number: 5276967Abstract: A flexible, twin-blade razor unit employing a corrugated spacer for providing improved cutting effectiveness. The corrugations increase the rigidity of the blades, which, in turn, decreases the amplitude of any vibration introduced into the blades.Type: GrantFiled: April 29, 1993Date of Patent: January 11, 1994Assignee: Warner-Lambert CompanyInventors: Frank A. Ferraro, Vincent C. Motta
