Abstract: A toothbrush comprising a handle member affixed to a flexible extension which is grippable by the user so that the flexible end is in contact with the heel of the palm of the user to flex when force is applied by the user to the head of the toothbrush. Rubberized inserts are also provided on the handle of the toothbrush to provide improved gripping surfaces for the fingers and palm of the user.

Abstract: A merchandise display system includes a support from which merchandise can be suspended. The support includes a rod with a hook at its free end. The rod is angled down towards its free end. A member on one side of the merchandise restricts movement of the merchandise about a first axis of the support. An additional member on another side of the merchandise restricts movement of the merchandise about the first axis of the support. The system further includes a pair of stoppers, one stopper being attached to the member near a free end of the member and the other stopper being attached to the additional member near a free end of the additional member. The stoppers restrict movement of the merchandise about a second axis of the support. The stoppers each include a pair of flexible flaps which enable merchandise to be inserted onto a support and removed from a support.

Abstract: An oral brush is provided that includes an elongated body, a head portion extending from the body, and a plurality of bristles, formed of particular thermoplastic elastomers, extending from the body. In various embodiments, the thermoplastic elastomer has a Shore A hardness of at least 30; the thermoplastic elastomer is selected from the group consisting of polyetheramides, polyesters, styrene-ethylene-butylene-styrene block copolymers, polyurethanes, polyolefin elastomers, and mixtures thereof; and the thermoplastic elastomer has a flexural modulus of at least 5 MPa.

Abstract: A method and apparatus for coating a fiber used in oral hygiene. The method comprises aerosolizing a coating and projecting the aerosolized coating particles onto a target area of the fiber. The method also comprises recycling recaptured coating particles for reuse in fiber coating. An apparatus for coating oral hygiene fibers is also described.

Abstract: A dental hygiene article, including a dental floss, and a microcapsule associated with a portion of the floss. The microcapsule includes a pigment encapsulated within the microcapsule for changing the color of a portion of the floss associated with the microcapsule upon rupture of the microcapsule as an indication of use or release of an active agent.

Abstract: A toothbrush has an elongated handle with bristles disposed at one end extending outwardly from one surface of the handle. The handle is formed of a semi-rigid plastic material having a pair of flanges disposed on the surface opposite that of the bristles for controlling the flexure at various points along the handle length and a softer material is formed onto that portion of the handle containing the flanges to provide a soft grip for the user.

Abstract: The present invention relates to a toothbrush which exhibits superior interproximal and gingival margin cleaning. The toothbrush includes an elongated handle member connected to a toothbrush head member. The head is divided into two regions. A "toe" region is defined as the part of the head which is furthest from the handle and a "heel" region is the portion of the head which is closest to the handle. A multiplicity of bristles extend from the heel region of the head; the distal ends of these bristles form a longitudinally aligned concave shape when viewed on end.

Abstract: A plastic blister package for display and storage of a toothbrush has a base member and a closure member connected to one another by an integrally molded hinge. The base member and closure member have a pair of flanges, one overlying the other with package in the closed position, and a lip is provided on flange edge of the base member for receiving the edge of the closure member to seal the cavity formed by the two members. A pair of protuberances extend from the base flange and are received in interfitting engagement with a pair of openings found in the closure flange to substantially lock the package in the closed position.
