  • Patent number: 6012569
    Abstract: A toothbrush handling device for handling of toothbrushes during the manufacturing process. The device is a rigid toothbrush holder with fixed dimensions which is easily transported in a conveyor type apparatus. The holder is formed with a generally toothbrush-shaped portion and terminates in at least one cavity suitable to hold at least the head portion of the toothbrush such that the bristles do not contact any interior surface of the cavity. If only one cavity is present, it is large enough to permit a gripping mechanism to grasp a portion of the brush to permit the insertion of the brush into or the removal of the brush from the transport device. Also, if more than one cavity is present, the cavities are separated by a supporting wall. The device enables improved and easier handling of the toothbrushes during manufacturing and processing, and protects the bristles from damage during those processes.

  • Patent number: 5991958
    Abstract: A toothbrush having two head sections, the sections being normally biased to assume an angle with respect to each other, to thereby define a generally concave bristle tip configuration. The two sections of the head have facing ends joined by a thin bridge section integral with the two heads. In one embodiment, there is one bridge section near the lower surface of the head. In another embodiment, there are two longitudinally spaced bridge sections each near the lower head surface. In a third embodiment, the bridge section is a thin integral connection between facing ends of the two sections. In other embodiments, the two head sections are normally aligned and are also joined by a thin, integral bridge section, with the bristles of the head section most remote from the handle being of uniformly different lengths. The space between the two facing ends is filled with an elastomer, typically SANTOPRENE (brand). The two head sections define an articulated head.

  • Patent number: 5976508
    Abstract: A method for enhancing the antiplaque efficacy of an antibacterial dentifrice, comprising preparing a multicomponent dentifrice composition having a first dentifrice component containing an antibacterial agent and manganese coordination complex compound, and a second dentifrice component containing a peroxide compound; maintaining the first and second dentifrice components separately prior to use; combining the dentifrice components and applying the two components to the teeth and periodontium, whereby the dentifrice provides enhanced inhibition of plaque growth.

  • Patent number: 5946758
    Abstract: A toothbrush having a bristle-bearing head divided into at least two sections is disclosed. The free end section, when unstressed, is normally biased to assume an angle of about 15.degree. with respect to the other, to thereby define an articulated head. The two sections of the head have facing ends joined by a thin bridge or hinge section integral with the two head sections, the bridge or hinge forming a groove between adjacent head sections. The upper surface of the bridge section is substantially flush with the upper surface of the head (opposite to the bristle-bearing surface). The space between the two facing ends is filled with a soft elastomer of about 5 to about 30, preferably about 13 to about 30 Shore A hardness. This hinge construction defines an articulated head of limited flex motion, wherein, when utilized by the average adult brusher, who applies an average brushing force of 0.5 pounds, flexes to a substantially flattened position.

  • Patent number: 5863102
    Abstract: Methods and machines are disclosed to attach tufts of individual bristles to a toothbrush with a resiliently flexible head, wherein the flexible head may be segmented with joints connecting adjacent segments or it may be angled or curved or combinations thereof, and to then trim such tufts of individual bristles to a desired length--or lengths in the case of brushes with multi-level tufts--and to then round the free ends of the individual bristles in each such tuft. The disclosed method and apparatus require only the modification of conventional toothbrush tufting machines having tuft insertion tools that travel in a defined direction and the modification of conventional trimming machines and methods.
