Patent application numberDescriptionPublished
20090025162Electric toothbrushes - A toothbrush has a body, a brush head, and a neck extending between the body and the brush head. The toothbrush also has a massaging element, a plurality of bristles, and a plurality of massaging tips. The brush head has a front face and a rear face. The massaging element is disposed on the rear face of the brush head, while the plurality of bristles and the plurality of massaging tips extend from the front face.01-29-2009
20100133294MULTI-CHAMBER MATERIAL DISPENSING SYSTEM AND METHOD FOR MAKING SAME - Material dispensing systems and methods for make such systems are described. The material dispensing systems employ a collapsible container having at least two distinct chambers, and is at least partially surrounded by an elastically deformable band. The band stretches as the container is filled with a flowable composition, thereby creating potential energy which can then be used to dispense the composition in lieu of a propellant and/or pressurized container.06-03-2010

20100133301VALVE AND DISPENSER COMPRISING SAME - A valve having a sleeve comprising a sleeve wall including an inner surface; and a plug positioned within the sleeve, the plug comprising at least one portion that is elastically deformable. The plug forms a blind hole extending into the plug from one end thereof to define a plug side wall, and a flow passage that extends through the plug side wall that is either open or openable. The plug defines a valve closed position in an unstressed state, yet is capable of elastically deforming to define a flow channel between the plug and the sleeve in a valve open position. A dispenser containing such a valve is also provided.06-03-2010
20110083287Electric Toothbrushes - An electric toothbrush is provided. The electric toothbrush has a handle, a head with a carriers and a longitudinal axis, and a neck disposed between the handle and the head. A motor is disposed within the handle. A shaft is operatively connected to the motor. The shaft is operatively connected to the carrier to move the carrier in a first motion. The carrier is capable of moving in a second motion when subjected to user forces.04-14-2011
20110185520Electric toothbrushes - A toothbrush has a body, a brush head, and a neck extending between the body and the brush head. The toothbrush also has a massaging element, a plurality of bristles, and a plurality of massaging tips. The brush head has a front face and a rear face. The massaging element is disposed on the rear face of the brush head, while the plurality of bristles and the plurality of massaging tips extend from the front face.08-04-2011
20110259359Device For Dispensing A Personal Care Product - A device for dispensing a personal care product onto skin comprising: a brush head comprising a base and a plurality of bristles, and a device body operatively connected to said brush head about said base, said device body comprising: an outer container; an at least partially expanded collapsible bag disposed in the outer container, an elastic member surrounding at least a portion of the collapsible bag such that the elastic member is stretched axially and radially, the elastic member being constructed of an elastically extensible material that permits the transfer of infrared radiation through at least a portion of the elastic member; at least one fluid dispensing conduit in fluid communication with said collapsible bag, extending through said base.10-27-2011
20110259923Plug And Valve System - A plug for use in a valve system comprising a generally elongate elastically deformable plug body having a longitudinal axis and a first end and an opposing second end, said body forming a blind hole disposed extending in a longitudinal direction downwards from said first end, a flange juxtaposed with said first end and extending radially outboard, wherein said plug forms at least one orifice at least partially formed in said flange, whereby said plug is longitudinally elastically elongatable.10-27-2011
20110260082Plug And Valve System - A plug for use in a valve system comprising a generally elongate elastically deformable plug body having a longitudinal axis and a first end and an opposing second end, said body forming a blind hole disposed extending in a longitudinal direction downwards from said first end, a flange juxtaposed with said first end and extending radially outboard, wherein said plug forms at least one orifice at least partially formed in said plug body, whereby said plug is longitudinally elastically elongatable.10-27-2011
