Patent number: 7723629Abstract: An actuator assembly and packaging feature for an electric toothbrush is disclosed. The actuator assembly includes a positionable member accessible along the outer surface of the toothbrush body. The actuator assembly further includes a spring member retained within the interior of the toothbrush body which urges a cam member against the underside of the positionable member. The positionable member defines an aperture extending through its midsection within which is disposed a depressible member. The depressible member has an outer end which is also accessible along the outer surface of the toothbrush body. Upon pressing the depressible member, the cam member and spring are urged against an electrical circuit provided within the body of the toothbrush which is used to selectively operate a motor and drive mechanism to move one or more sets of bristles.Type: GrantFiled: July 9, 2007Date of Patent: May 25, 2010Assignee: Church & Dwight Co., Inc.Inventor: John G. Chan

Patent number: 5996845Abstract: The present invention relates to a self-closing liquid dispensing package comprising a liquid container and a self-closing flat channel valve in liquid communication with liquid container, wherein the liquid container comprises a reservoir portion for containing liquid. The reservoir portion is made of a thermoformed thermoplastic material. In one preferred embodiment of the present invention, the self-closing flat channel valve is in liquid communication with the container via a connection portion wherein the connection portion comprises a stiffening crease. The package of the present invention is useful for multiple use of various liquid products having a wide range of viscosity.Type: GrantFiled: November 2, 1995Date of Patent: December 7, 1999Assignee: The Procter & Gamble CompanyInventor: John G.

Patent number: 5529224Abstract: A self-closing liquid dispensing package comprises a liquid container and a self-closing flat channel valve. The channel valve has an inlet adjacent to and in liquid communication with the liquid container. It also has a mouth, a first sheet member, and a second sheet member wherein the first and second sheet members have an original planar position and longitudinal edges, are indexed face-to-face, and are sealed together along longitudinal edges and wherein the first and second sheet members are sufficiently flexible to arch away from each other to form a flow channel therebetween to permit a flow of contained liquid in response to external pressure applied to the liquid container. At least one of the sheet members is sufficiently resilient to return the first and second sheet members to the original planar position when the external pressure is released.Type: GrantFiled: May 27, 1994Date of Patent: June 25, 1996Assignee: The Procter & Gamble CompanyInventors: John G. Chan, Tatsuya Taniguchi
