  • Publication number: 20010053375
    Abstract: Delivery systems for whitening teeth are provided. The delivery system includes a strip of material sized to cover a front surface of a plurality of teeth and a layer of a tooth whitening substance in contact with the strip of material. The tooth whitening substance includes a gelling agent and a whitening active selected from the group consisting of peroxides, metal chlorites, perborates, percarbonates, peroxyacids, hypochlorites, and combinations thereof. The delivery system further includes a release liner having a coating thereon, wherein the release liner exhibits less affinity for the tooth whitening substance than the tooth whitening substance exhibits for itself and for the strip of material.

  • Patent number: 6277458
    Abstract: The present invention relates to a laminated structure comprising an adhesive coated strip which is mounted upon a release strip wherein the release strip includes a partible break and wherein the release strip farther includes a tab. Deflection of the release strip tab in a direction away from the adhesive coated strip generates a partial separation of the release strip tab from the general plane of the release strip at the partible break causing an edge of the adhesive coated strip to be exposed for grasping by the user. The present invention also relates to methods for removal of an adhesive coated strip from the release strip.

  • Patent number: 6136297
    Abstract: A system for delivering an oral care substance to the oral surface, the delivery system comprising a strip of flexible material having a sufficient flexibility to form to the contours of the oral surface. The strip of material is readily conformable to oral surfaces without permanent deformation when the delivery system is placed there against. The oral care substance is applied to the strip of material such that when the delivery system is placed on the oral surface the active contacts the surface. The oral care substance also provides adhesive attachment between the strip of material and the oral surface so as to hold the delivery system in place for a sufficient amount of time to allow the active to act upon the oral surface.

  • Patent number: 5891453
    Abstract: A system for delivering a tooth whitening substance to a plurality of adjacent teeth, the delivery system comprising a strip of flexible material having a sufficient flexibility to form a curved shape on a plurality of adjacent teeth and a tooth whitening substance. The strip of material is readily conformable to the teeth surfaces and to interstitial tooth spaces without permanent deformation when the delivery system is placed thereagainst. The tooth whitening substance is applied to the strip of material such that when the delivery system is placed on the surface of the teeth, the substance contacts the surface providing an active onto the surface. The substance also provides adhesive attachment between the strip of material and the surface to hold the delivery system in place for a sufficient amount of time to allow the active to act upon the surface.
