Patents by Inventor Gert Silber

Gert Silber has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11464317
    Abstract: An applicator device includes a top and a bottom layer of a flexible material tightly connected at their borders. An edge constitutes a grip zone to handle the applicator. Parallel weakening lines in each layer define an application section and closely surround a pad of a material capable to retain an agent or an elevation constituting a confinement structure for an agent. The superposition of weakening line and border of agent carrying material or the elevation constituting a part of the confinement structure avoids a contact of the flexible material with the surface to be treated as the carrying material layer or the confinement structure serve as a spacer. As a consequence, the applicator is suited to be used on highly sensitive surfaces like skin or mucosa.

  • Publication number: 20040042976
    Abstract: A material is proposed as an essential abrasive component for cleaning agents in cleaning products for delicate surfaces which is essentially composed of platelets. These platelets are preferably shaped without sharp points, i.e. their circumference is similar to a polygon whose corners do not show angles that are in the majority smaller than 30° and greater than 330°. Glass flakes are for example such a material. The abrasive component of the invention may for example be used for the manufacture of toothpastes and prophylaxis pastes that are efficient but nevertheless not harmful to teeth.

  • Patent number: 6576225
    Abstract: A dental care composition for the prophylactic dental hygiene (prophylactic paste) comprises as principal components the following: from 10 to 80% by weight, preferably from 35 to 55% by weight, of a polishing body containing plate shaped rock particles, preferably perlite particles; from 20 to 80% by weight, preferably from 40 to 50% by weight, of a nonionic, preferably polymeric surface active agent; and from 0 to 20% by weight, preferably from 1 to 10% by weight, of an emulsifier or emulsifier blend. Polyethylene glycols (Macrogol) having molecular weights of from 200 to 1,000, preferably of from 200 to 600, are particularly suited as pure compounds or as a blend of different variants having different molecular weights. The dental care composition shows a smooth and soft consistency and has only a weak tendency of being splashed during its application in the mouth.
