The pivot member is attached to the handle, and includes an exterior contact surface that extends along the length of the cartridge. The cartridge and the pivot member are preferably pivotal relative to one another. The cartridge includes a frame, and one or more razor blades. Each of the one or more razor blades includes a cutting edge, and the cutting edges are positioned contiguous with a shave plane. The pivot member is positioned forward of the one or more razor blades, and positioned such that at least a portion of the exterior contact surface of the pivot member is disposed contiguous with the shave plane.Type: GrantFiled: October 21, 2002Date of Patent: October 26, 2004Assignee: Eveready Battery Company, Inc.Inventor: Thomas A. Follo

Publication number: 20040181953Abstract: In a shaving implement a handle includes a shaving head that defines an interior area. An actuator is coupled to the shaving head for movement between a neutral position, and a cartridge ejecting position. The cartridge retainer includes a portion projecting outwardly from the shaving head defining at least one cartridge engaging surface adapted to slidably engage a complimentarily shaped slot that extends longitudinally of a rear surface defined by a razor cartridge mounted to the shaving implement. The razor cartridge is releasably coupled to the cartridge retainer so that it is movable between a non-rotated and a rotated position with the cartridge being urged toward the non-rotated position in response to an externally applied force.Type: ApplicationFiled: February 24, 2004Publication date: September 23, 2004Applicant: Eveready Battery Company, Inc.Inventors: Thomas A. Follo, Paul R. Dansreau, Max Arthur Lembke, John F. Pacilio

Publication number: 20040181954Abstract: In a shaving implement a razor cartridge is pivotally coupled to a handle for rotational movement about a pivot axis. The razor cartridge includes a leading surface and a trailing surface and at least one blade positioned between the leading and trailing surfaces, the blade defining a cutting edge that is at least partially exposed. The pivot axis is located adjacent to the leading surface so that during a shaving operation, externally applied forces generated by drawing the razor cartridge and thereby the exposed portion of the cutting edge over a hirsute surface, causes the razor cartridge and the cutting edge to rotate into the hirsute surface.Type: ApplicationFiled: February 26, 2004Publication date: September 23, 2004Applicant: Eveready Battery Company, Inc.Inventors: Thomas A. Follo, Paul D. Richard

Publication number: 20040177519Abstract: A razor includes a handle, a flexible neck extending from the top of the handle and a blade-carrying razor head pivotally fitted on the distal end portion of the neck. A lower portion of the handle functions as an actuator for dispensing shaving material contained within the handle and is operable between a stop position and a dispensing position. The neck is structured to flex and/or twist in a yielding action in response to external forces as the blade-carrying razor head travels over irregular or varying contours of the skin surface. The flexible neck may be formed to include a scoop for directing a stream of water through the blade-carrying razor head in a fanned array, providing an enhanced flushing action to remove debris and residue which accumulates on the blades.Type: ApplicationFiled: March 14, 2003Publication date: September 16, 2004Inventors: Louis D. Tomassetti, Christian T. Scheindel

Publication number: 20040128835Abstract: A blade cartridge for a wet shaving device comprises a housing including a lower housing member and an upper housing member cooperating to define a cavity. First and second blade assemblies are disposed within the cavity. Each of the first and second blade assemblies includes at least one blade defining a cutting edge, wherein the cutting edge of the blade of the first blade assembly generally faces the cutting edge of the blade of the second blade assembly to permit bidirectional shaving.Type: ApplicationFiled: October 16, 2003Publication date: July 8, 2004Applicant: Eveready Battery Company, Inc.Inventors: David C. Coffin, Randy Nicolosi, Andrew J. Pennella

Patent number: 6739053Abstract: A hair clipping device includes a housing, a bladeset engageable upon the housing and including at least one stationary blade and at least one moving blade configured for reciprocal movement relative to the at least one stationary blade. The stationary blade has a first cutting edge and a second cutting edge, the at least one moving blade including a first moving edge configured for reciprocal movement relative to the first cutting edge, and a second moving edge configured for reciprocal movement relative to the second cutting edge. The housing defines a cutting location for the blades and the bladeset is rotatably engageable on the housing between a first position in which the first edges are employed, and a second position in which the second edges are employed. The housing encloses an apparatus for creating a vacuum, and defines a vacuum intake.Type: GrantFiled: December 14, 2000Date of Patent: May 25, 2004Assignee: Wahl Clipper CorporationInventors: James Edward McCambridge, Jon Thomas Freas, Jason M.

Publication number: 20040020053Abstract: A blade unit (2) of a safety razor has a flexible blade assembly (5) comprising plurality of blades (16) with parallel cutting edges (17), mounted on a resiliently compliant support structure (4) that includes several spring elements (12) disposed along the blade unit (2) to oppose local deformation of the blade unit (2) under shaving forces imposed in the regions where the spring elements (12) act. The blade unit is able to conform closely to skin undulations due to varying deformation of the support structure (4) along the blade unit being permitted. In an embodiment the support structure (4) is a one piece moulding of resiliently flexible material and includes an upper frame (6) on which the blade assembly (5) is carried, a sub-frame (7) and a base (8), the upper frame (6) and the sub-frame (7) being connected together by a living hinge (9) and the sub-frame (7) and base (8) being connected by another living hinge (10) so that the support structure is Z-shaped in cross-section.Type: ApplicationFiled: April 10, 2003Publication date: February 5, 2004Applicant: THE GILLETTE COMPANYInventor: Kevin J.
