20080209649 | Toothbrush, as Well as Toothbrush Head Therefor - A toothbrush and toothbrush head with a bristle carrier, on which a bristle section featuring a multitude of filaments is arranged. At least one filament is provided with a taper on its free end with a shape other than a rotationally symmetrical shape to preserve a high flexural strength of the filament in one direction. The taper is a flat-pressed scarfing such that the filament has a greater flexural strength with respect to a first lateral axis than with respect to a second lateral axis perpendicular to the first lateral axis in the region of the taper. The flat-pressed scarfing at the point of the filament improves penetration into the interdental spaces, while the higher geometrical moment of inertia of the wide side reduces the bending of the filament during use. | 09-04-2008 |
20100306944 | TOOTHBRUSH BRISTLE AND METHOD FOR MANUFACTURING SUCH A BRISTLE - A method for manufacturing filaments for personal hygiene articles is described. The filaments are provided with a surface structure with at least one surface recess such as dimples and/or pittings. The filament includes at least a portion made of a material soluble by a corrosive agent and is covered in part with a cover layer stable to the corrosive agent such that a surface portion of the filament body substantially corresponding to the at least one surface recess is uncovered. The filament body is contacted with the corrosive agent for a limited time to create the surface recess in the uncovered surface portion. | 12-09-2010 |
20110061191 | Toothbrush, Toothbrush Filament and Method for Manufacturing Same - The present invention relates to a toothbrush. The invention relates in particular to a toothbrush filament having a filament body surrounding a matrix material in which grains are embedded, wherein the matrix material and the grains have a different resistance to etching so that by etching the matrix material and/or the grains a surface structure can be created on the filament body at least in the area of the tapering end section. According to one aspect of the present invention, grains having a shell structure with a grain shell, in which is encapsulated a grain core comprising a core material different from the shell material, have been embedded in the matrix material of the filament. | 03-17-2011 |
20130025615 | HANDLING AID FOR DENTAL FLOSS - A dental floss comprising a first connecting element and a second connecting element wherein the connecting elements interact to form a connecting assembly and thereby form a loop of dental floss. This dental floss can be used for forming a dental floss loop by engaging the first connecting element and the second connecting element. | 01-31-2013 |
20130025616 | HANDLING AID FOR DENTAL FLOSS - A dental floss clamp comprising a screw connection having a threaded nut and a threaded bolt which is moveable within a longitudinal axis of the threaded nut and can be screwed therein wherein the threaded nut comprises a jacket and has an interior thread and an interior groove; the threaded bolt has an exterior thread and an exterior groove; each turn of the interior thread has a first flank , and a second flank, each having a pitch; and wherein the pitch of the second flank with respect to the longitudinal axis of the threaded nut is greater than the pitch of the first flank. | 01-31-2013 |
20130025622 | DENTAL FLOSS COMPRISING PLASTIC PARTS - A method for producing a length of dental floss having a plastic part attached comprising the steps of providing a mould having a cavity; disposing a length of dental floss within the cavity; arranging the dental floss within the cavity such that the dental floss enters the cavity at a first location x and exits the cavity at a second location y and wherein the path length of the dental floss within the cavity is greater than the linear distance between the first location x and the second location y; and injecting a plastic material into the cavity to encapsulate the floss. | 01-31-2013 |
20130025623 | HANDLING AID FOR DENTAL FLOSS - A dental floss clamp, said clamp comprising a first limb and a second limb which are mutually hinged at a first end of each limb; each limb having a plurality of projections and recesses configured such that when the limbs are brought together the projections of the first limb can engage with the recesses of the second limb and the projections of the first limb press laterally on the projections of the second limb in order to clamp a length of dental floss. | 01-31-2013 |
20140352091 | MANUAL TOOTHBRUSH CONCEPT BEING COMBINED FROM THREE PARTS - A toothbrush comprises a head, a neck portion and a handle, wherein the neck portion and the handle portion are connected to one another via a coupling element. The connection is constructed as an inseparable connection, i.e., after being combined once, the neck portion and the handle cannot be separated without the brush being destroyed by such separation. A method for producing such a toothbrush may comprise the following steps: providing a head, a neck portion, a handle, and a coupling element, and combining the neck portion to the handle by the coupling element so that an irreversible connection is formed. | 12-04-2014 |
20140352093 | METHOD FOR PRODUCING A TOOTHBRUSH AND TOOTHBRUSH PRODUCED THEREBY - A method for producing a toothbrush comprises providing a head, a neck portion, and a handle; providing a coupling element; and combining the neck portion to the handle by the coupling element so that an irreversible connection is formed. The individual parts of the toothbrush to be formed can be produced in parallel or successively, wherein some of the parts can be produced by injection molding. A toothbrush formed by the method comprises a head, a neck portion, and a handle; these elements can be produced as building blocks separately and may be connected to one another via a coupling element to form an inseparable connection. | 12-04-2014 |
