Patent number: 6041926Abstract: A cartridge dispenser for razor blade cartridges including latches that retain cartridges in predetermined positions permitting connection to a handle connecting structure on a handle as the handle is moved toward the cartridge, each latch having a latch camming structure that is shaped and positioned to interact with corresponding handle camming structure so as to cause the latch to be deflected and to unlatch a cartridge as the handle is moved toward and connected to cartridge connecting structure of a cartridge. The dispenser also has blade unit dividers that extend from the base, are substantially perpendicular to the base, and define blade unit regions in which the blade units are received, and angled dividers that extend from the ends of respective blade unit dividers at acute angles with the base and define angled regions through which the blade units pass in delivery to and removal from the blade unit regions and in which the cartridge connecting structure is received.Type: GrantFiled: February 19, 1997Date of Patent: March 28, 2000Assignee: The Gillette CompanyInventors: John D.

Patent number: 5784790Abstract: A cartridge-connecting subassembly for a shaving razor handle including a cartridge connecting structure, a handle connecting structure, and a movable component within the cartridge connecting structure that interacts with a replaceable cartridge when it is connected. The cartridge connecting structure and handle connecting structure have outer side surfaces that mate with inwardly directed surfaces of the cartridge and handle so that the subassembly is substantially covered when it is mounted in the handle and a cartridge is connected. The subassembly has an assembly opening for receiving the movable component during assembly, a cartridge interaction opening through which the component is movable for interaction with the cartridge, and blocking structure that retains the movable component in the subassembly. The movable component is an ejector structure that is separate from the cartridge connecting structure. The subassembly is connected to the handle by staking.Type: GrantFiled: February 19, 1997Date of Patent: July 28, 1998Assignee: The Gillette CompanyInventors: William C. Carson, III, Alejandro C. Lee, Stephen C. Metcalf, Paul Nowak, Robert A. Trotta, Charles B. Worrick

Patent number: 5497550Abstract: A shaving system with a blade member with a cutting edge of wedge shape that is defined by main facets with an included facet angle in the range of 10.degree.-17.degree. in the region forty micrometers from the cutting edge. The blade is mounted between leading and trailing skin-engaging surfaces so that the blade tangent angle is less than 20.degree. and the interior main facet of the blade is disposed at an angle of more than 150.degree. to a reference line that extends from the cutting edge of the blade to the skin-engaging point next forward of the blade edge.Type: GrantFiled: February 3, 1994Date of Patent: March 12, 1996Assignee: The Gillette CompanyInventors: Robert A.

Patent number: 5299354Abstract: An oscillating wet shave razor with a battery powered motor rotating an eccentric element within the head portion of the razor handle to generate an oscillating vibration signal which is transmitted to the razor blade cartridge to desensitize the facial nerves from the discomforts of shaving. The vibration which is transmitted to the cartridge is partially damped in the direction perpendicular to the surface of the cartridge that engages the user's face so that the blades mounted in the cartridge tend not to chop at the whiskers of the user's beard during shaving.Type: GrantFiled: October 11, 1990Date of Patent: April 5, 1994Assignee: The Gillette CompanyInventors: Stephen C. Metcalf, Robert A. Trotta, Donald R. Chaulk, Hiroshi Harigai

Patent number: 5232127Abstract: A dispenser device for a foam producing gel includes an actuator and a hood, the actuator being mounted at the top of a gel container and having an inlet contacting the valve stem of the gel container and a nozzle having an outlet directed radially outwardly from the top of the container. The hood is open at the bottom and engages the outer surface of the actuator to cover the actuator when not in use. An opening is provided in the hood and a notch in the rim of the opening contacts a detent on the outer surface of the actuator to ensure that the hood opening is opposite the nozzle outlet of the actuator when the hood is in place. The hood opening when so positioned serves to inhibit excess foaming of gel remaining between the actuator inlet and nozzle outlet when the hood is in place after usage, and a notch is formed in the nozzle structure below the actuator outlet to provide a path of flow downwardly from the outlet as foamed product expands outwardly from the outlet.Type: GrantFiled: October 30, 1991Date of Patent: August 3, 1993Assignee: The Gillette CompanyInventors: Robert A. Trotta, Brian A. Rogers, Stephen C. Metcalf

Patent number: 5067238Abstract: A shaving system of the wet shave type includes body structure that incorporates guide structure and fixed skin-engaging structure with skin-tensioning surface structure. Blade structure, carried by the body structure rearwardly of the fixed skin-engaging structure, has a cutting edge extending along the length of the body structure, and movable guard structure is carried by the body structure between and adjacent to the fixed skin-engaging structure and the cutting edge of the blade structure. The movable guard structure includes a series of skin-tensioning crest portions disposed for skin-engagement between and adjacent to the fixed skin-engaging structure and the cutting edge. The movable guard structure is positioned in the body structure in engagement with biasing structure for dynamic movement of the movable guard structure relative to the fixed skin-engaging structure against the biasing structure as guided by the guide structure in the course of shaving.Type: GrantFiled: September 28, 1990Date of Patent: November 26, 1991Assignee: The Gillette CompanyInventors: Gary R.
