Patent number: 6852262Abstract: Methods of manufacturing razor cartridges are provided. One method includes loading a support portion of a supported blade into an elongated blade slot defined by a core member, the core member being configured to define a portion of a molding cavity defining the shape of the cartridge housing; and delivering a resin to the molding cavity to form the housing and capture a portion of the blade in the resin. In another method, a plurality of razor cartridges are manufactured substantially simultaneously by (a) removably mounting each blade on a core member; (b) placing each core member in a molding cavity; and (c) delivering a resin to the molding cavities to form at least a portion of the cartridge housing and capture a portion of the blade in the resin.Type: GrantFiled: May 9, 2002Date of Patent: February 8, 2005Assignee: The Gillette CompanyInventors: William R. Brown, Jr., William C. Carson, Alexander T. Chenvainu, Thomas A. Christman, Kenneth E. Johnson, Charles P. Kiricoples, Alejandro Lee, Cardy J. Louis, Helge Zimmet

Patent number: 5881706Abstract: A toy rocket launcher for launching a common bottle such as a plastic two liter beverage bottle in the air with pneumatic pressure. The toy rocket launcher includes a support stand having a top member and a plurality of support legs downwardly depending from the top member. The top member has a hole through which the upper end of a conduit is upwardly extended. An end of a hose is coupled to a lower end of the conduit to fluidly connect the hose to the conduit. A pneumatic pump is attached to a second end of the hose for pumping air into the hose. The upper end of the conduit is inserted into an opening in the neck of an inverted beverage bottle.Type: GrantFiled: September 3, 1998Date of Patent: March 16, 1999Inventor: William C. Carson

Patent number: 5794343Abstract: A razor blade assembly includes an elongate platform supporting a pair of blades and an elongate guard member disposed adjacent a forward edge of the platform. The guard member has a plurality of fins each spaced one from the other. In preferred embodiments each fin has its uppermost surface below a rearwardly disposed fin and the uppermost surfaces collectively lie on an outwardly convex arcuate surface, and each successively rearward fin is inclined more towards the leading blade edge than the preceding adjacent fin. The elongate platform is provided with a plurality of apertures extending through the platform between a plurality of webs and the guard member is molded in place onto the platform. Portions of the guard member material flow through the apertures and surround webs during the molding process to maintain the guard member in place.Type: GrantFiled: May 12, 1997Date of Patent: August 18, 1998Assignee: The Gillette CompanyInventors: Alejandro Lee, William C. Carson, III, Douglas R. Kohring

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: 5526567Abstract: A shaving system includes a platform member with a support surface that has a plurality of apertures therein and guard structure integral therewith and disposed forwardly of the support surface, a cap member with a plurality of post elements for disposition in the apertures in the support structure, a primary blade member having a planar body and a cutting edge, a secondary blade member having a planar body and a cutting edge, each blade member having a plurality of apertures and at least two of the apertures having spaced locating surfaces for positioning engagement with the post elements, and a plurality of discrete spacer members disposed on the post elements and between the primary and secondary blade members. The post elements extend through the apertures in the blade members, the spacers and the platform member and preferably are mechanically deformed to secure the primary and secondary blade members with their cutting edges in spaced parallel relation in a fixed shaving geometry.Type: GrantFiled: April 14, 1995Date of Patent: June 18, 1996Assignee: The Gillette CompanyInventors: William C. Carson, III, Frederick R. Borden
