Patent number: 9833061Abstract: A dental hygiene device such as an interdental brush includes a handle, a brush head having bristles extending therefrom, and a neck portion extending between the brush head and the handle. The neck portion of the dental hygiene device is configured to provide two modes of operation, a first cleaning mode of operation wherein the brush head contacts the teeth at a first pressure for a given application pressure, and a second cleaning mode of operation wherein the brush head contacts the teeth at a second pressure, greater than the first pressure, for the same given application pressure.Type: GrantFiled: September 14, 2015Date of Patent: December 5, 2017Assignee: SUNSTAR AMERICAS, INC.Inventors: Russell G. Kalbfeld, Leoncio Angel Gonzalez

Patent number: 9131768Abstract: A dental hygiene device such as an interdental brush includes a handle, a brush head having bristles extending therefrom, and a neck portion extending between the brush head and the handle. At least some of the bristles may have a substantially triangular cross section. The neck portion defines a longitudinal axis and has a first bending stiffness when subject to loading in a first direction that is substantially perpendicular to the axis, and a second bending stiffness when subjected to loading in a second direction that is substantially perpendicular to the axis. The first bending stiffness is less than the second bending stiffness such that the dental hygiene device can be reoriented during use to provide a more gentle or a more robust cleaning to interdental spaces.Type: GrantFiled: May 9, 2011Date of Patent: September 15, 2015Assignee: SUNSTAR AMERICAS, INC.Inventors: Russell G. Kalbfeld, Leoncio Angel Gonzalez

Patent number: 8662092Abstract: A dental floss dispensing unit includes a housing, a supply spool, and a metering element. The supply spool is coupled to the housing and has a length of floss wound thereabout. The length of floss has a free end extending from the housing and a plurality of alternating and distinct first and second floss segments. The metering element engages the length of floss and provides resistance to removal of the length of floss from the housing. A magnitude of the resistance changes as each floss segment moves into engagement with the metering element, thereby providing a tactilely detectable indication to the user that one of the first or second segments is emerging from the housing. The dispensing unit is configured to allow the supply spool to be manually rotated without manipulation (e.g., disassembly) of the housing for rewinding floss onto the spool.Type: GrantFiled: December 30, 2011Date of Patent: March 4, 2014Assignee: Sunstar Americas, Inc.Inventors: Russell G. Kalbfeld, David L. Barcus, Chad Misner

Patent number: 8663520Abstract: A method of making interdental cleaners includes forming a slug by extruding material in a direction of extrusion to form a first slug portion having a generally rectangular first cross-section and a second slug portion having a tapering second cross-section that extends away from the rectangular first cross-section. The method also includes stamping the slug substantially perpendicular to the direction of extrusion to form a plurality of cleaner blanks. The stamping forms the first slug portions into handle portions of the cleaner blanks, and the second slug portions into shaft portions of the cleaner blanks. The shaft portions include two pairs of converging surfaces that taper toward each other to define a point. The method also includes attaching cleaning members to the ends of the shaft portions.Type: GrantFiled: July 28, 2009Date of Patent: March 4, 2014Assignee: Sunstar Americas, Inc.Inventors: Russell G. Kalbfeld, Leoncio Angel Gonzalez

Patent number: 8578949Abstract: A multi-texture dental floss includes distinct and alternating segments having varying textures, including smooth segments and textured segments. The smooth segments are more easily inserted into the spaces between teeth, while the textured segments more effectively remove plaque and other debris therefrom. Methods of making the multi-texture floss are also disclosed, including methods that allow the floss to be made as a continuous thread having a plurality of alternating segments, such that the floss can be wound onto a spool for storage and dispensing.Type: GrantFiled: January 16, 2009Date of Patent: November 12, 2013Assignee: Sunstar Americas, Inc.Inventors: Russell G. Kalbfeld, David L. Barcus
