Publication number: 20240023701Abstract: The present invention concerns a process for producing toothbrushes covered with bristles in an anchor-free manner, in which a tuft of bristles with cylindrical bristles and/or pointed bristles is introduced into a receiving recess of a mold of a bristle-providing machine and, by means of a profiled pin guided in the receiving recess, force is applied to the end facing the pin of the bristles of the tuft of bristles for the alignment thereof, so that the bristles of the tuft of bristles are aligned by means of an end face of the profiled pin and, as a result, form the topography that complements the topography of the end face of the profiled pin, wherein the profiled pin has on the end face that acts on the bristles a discontinuous surface, which forms multiple levels. This achieves a bristle area configuration that has multiple areas of use. A correspondingly produced toothbrush is also described.Type: ApplicationFiled: August 28, 2023Publication date: January 25, 2024Applicant: TRISA HOLDING AGInventors: Walter HESS, Oskar TREVISAN

Publication number: 20220079328Abstract: A brush product, in particular a toothbrush, having a base body with a head part with a front and a rear side, which includes a bristle carrier with a longitudinal axis and a transverse axis and a bristle field protruding therefrom, wherein the bristle field is formed by at least one group of cleaning elements; a handle part; and a neck part connecting the head part and the handle part; wherein the bristle carrier is provided with bristles which are mounted without being anchored and wherein the bristle carrier includes substantially a central support area, an upper support area, a lower support area, a right support area and a left support area, in which the groups of cleaning elements are arranged. Also, a corresponding method and tool.Type: ApplicationFiled: November 23, 2021Publication date: March 17, 2022Applicant: TRISA HOLDING AGInventors: Reto STRÄHLER, Jost LÖTSCHER, Oskar TREVISAN, Martin ZWIMPFER

Patent number: 9173480Abstract: The tips of pointed bristles are mechanically processed in order to remove any corroded threads or residual threads from the tip. Mechanically processed pointed bristles are fed to a receptacle recess of a tool in bundles, and aligned by means of a pin guided in the receptacle recess. The pointed bristles are pushed through the passage of the bristle carrier plate, and the end section are subsequently melted by means of a heating die in order to attach the pointed bristles to the bristle carrier plate. The mechanical processing of the tips of the bristles enables an error-free further processing of the pointed bristles utilizing the bristling method, particularly the AFT method.Type: GrantFiled: July 26, 2013Date of Patent: November 3, 2015Assignee: TRISA HOLDING AGInventors: Jost Loetscher, Oskar Trevisan

Patent number: 8840192Abstract: In the production of toothbrushes, the neck part and the head part are bent relative to each other from the original shape thereof by a predetermined angle (?) in the hot state of the toothbrush body. Thereafter, the force applied to the toothbrush body by the stretching device in order to bend the toothbrush body is removed so that the toothbrush body can bend back into the original shape thereof. The risk of fractures, in particular brittle fractures, can be greatly reduced by said action. The method is advantageous, in particular, if the toothbrush body was heated during processing by ultrasonic welding.Type: GrantFiled: December 20, 2010Date of Patent: September 23, 2014Assignee: Trisa Holding AGInventors: Jost Lotscher, Oskar Trevisan
