  • Patent number: 7310848
    Abstract: A toothbrush having a head placed at a front longitudinal end of a handle made overall as a single piece. The head has flexible brushing elements on its upper surface. The toothbrush is equipped with an arm articulated at one end, and provided at the opposite free end with a protective cover for the brushing elements. The general thickness of the arm gradually increases from its articulation end to the cover so as to form a profile projecting from a longitudinal surface of the rear portion of the handle, by virtue of which the gripping surface of the handle is increased. The articulation of the arm on the handle is designed to allow it to describe at least two different rotations about two substantially orthogonal geometric axes.

  • Publication number: 20050287085
    Abstract: The invention concerns a composition comprising at least one titanium and fluorine derivative for reinforcing materials based on natural or synthetic apatite, in particular teeth, bones, dental implants and surgical prostheses. The inventive compositions enable in particular apatite materials to be enriched with titanium and fluorine. The invention also concerns a method for reinforcing apatite-based materials using said compositions, and use of titanium and fluorine derivatives to fight against staining of apatite-based material.

  • Patent number: 6050273
    Abstract: A brush includes a mascara applicator and a stem with a grip, the stem having first and second ends substantially aligned with each other along a common axis, and an intermediate non-rectilinear portion connecting the first and second ends, the intermediate non-rectilinear portion having an offset shape protruding in a first direction from the common axis, the mascara applicator being attached to the first end and protruding from the common axis in a second direction substantially opposite the first direction, and the grip being attached to the second end of the stem.

  • Patent number: 5902063
    Abstract: A container with a brush for the application of a product such as mascara includes a scraping sleeve made fast to the neck of the container and which forms at least one constriction permitting the insertion of the brush into the container and its dry-squeezing during withdrawal from the container. The constriction extends transversely inside of the sleeve and defines on either side of the constriction a chamber through which a stem of the brush passes and another chamber opposite to the brush receiving chamber into which the free ends of the bristles are received. The bristles being squeezed while passing through the constriction. The transverse dimension of the constriction is smaller than the length of the bristles so that a certain amount of the product can be retained on the ends of the bristles while the portion of the bristles in the constriction is dry-squeezed.

  • Patent number: 5248212
    Abstract: The invention relates to a device for the delivery of any type of product held in a reservoir with flexible and deformable wall. The device is essentially comprised of means (4) for the delivery of a product, which means are housed in a reservoir (2) with flexible and deformable wall (3) and which may be actuated by an outside pressure (F) exerted on the deformable wall of the reservoir. The device applies for example to the delivery and application of a cosmetic product on the skin or the nails.

  • Patent number: 4839492
    Abstract: In a device of the plasma scalpel type (40, 41) including at least two spaced-apart electrodes (21, 22) subjected to electrical potential differences such that electric arcs take place therebetween, together with structures for producing at least one fluid flow passing through a region of space where said electric arcs occur, the potential differences being alternating potential differences at medium or high frequency, the ends of said electrodes are substantially filiform and forming an angle therebetween which is preferably acute, and a voltage step-up transformer is incorporated therein in order to deliver the alternating potential differences, with the fluid flows arriving from within the angle or along at least one of said electrodes.
