Description

Poil destine ä garnir une brosse Les poils de brosses, notamment les poils en matiere synthetique destines ä garnir des brosses hy- gi6niques telles que des brosses ä dents, presentent des extremites coupantes qui endommagent 1'email des dents et irritent les geneives au point de les faire saigner. De plus, la sterilisation de ce@s poils, pose des problemes de manutention Tors .de leer fabrication. Bristles intended to garnish a brush The bristles of brushes, in particular bristles made of synthetic material intended to garnish hygienic brushes such as toothbrushes, have sharp ends which damage the enamel of the teeth and irritate the gums to the point of make them bleed. In addition, the sterilization of ce @ s hair, poses Tors handling problems .de leer manufacturing.

Ort a cherche ä ameliorer ces poils en polissant leurs extremites, mais 1e resultat obtenu est loin d'etre satisfaisant. En effet, les extremites polies des poils offrent une surface ä peu pres plane et linse mais les bords de cette surface restent aigus et cou- pants. Etant donne que les poils ne frottent pas uniquement nur la surface de leurs extremites, 1e re- sultat escompte West pas atteint et 1e polissage des extremites des poils ne peut etre considere comme une solution valable, .d'autant plus qu'au cours du polissage, les poils accumulent une certaine quantite de poussieren et autres impuretes. Ort has sought to improve these bristles by polishing their ends, but the result obtained is far from satisfactory. Indeed, the polished ends of the bristles provide an approximately flat and smooth surface but the edges of this surface remain sharp and sharp. Since the bristles do not rub only on the surface of their ends, the expected result is not achieved and the polishing of the ends of the bristles cannot be considered as a valid solution, especially since during the polishing, the bristles accumulate a certain amount of dust and other impurities.

Dann 1e but de remedier ä ces inconvenients, la presente Invention. a ,pour objet un :poil destine ä garnir une brosse, caracterise par 1e fait qu'au moins une de ses extremites presente un renflement ar- rondi. In order to remedy these drawbacks, the present invention. the object is a bristle intended to garnish a brush, characterized by the fact that at least one of its ends has a rounded bulge.

L'invention a egalement pour objet un procede pour la fabrication du poil susmentionne, caracterise par 1e fait que 1e renflement est obtenu par chauffage et .fusion de 1'extremite du poil. The invention also relates to a process for the manufacture of the aforementioned hair, characterized in that the first bulge is obtained by heating and .fusion of the end of the hair.

Le dessin annexe represente, ä eitre d'exemple, une forme d'execution de 1'objet de 1'invention. L'unique figure est une vue en elevation du poil selon 1'invention. The appended drawing represents, by way of example, one form of execution of the object of the invention. The single figure is an elevational view of the hair according to the invention.

Le poil represente sur la fig. 1 est :en matiere synthetique, par exemple en polyamide, et est forme par une tige 1 dont 1'extremite 2 prAente .un renfle- ment 3 dont la surface est arrondie, ce renflement etant obtenu par chauffage et fusion de 1'extremite du poil. The hair represented in fig. 1 is: made of synthetic material, for example polyamide, and is formed by a rod 1 whose end 2 presents a bulge 3 whose surface is rounded, this bulge being obtained by heating and melting the end of the hair.

Le poil represente, plus particulierement destine ä garnir une brosse ä dents, ,peut etre utiIise pour tous les types de brosses hygieniques etant donne qu'il peut etre monte de la meme fagon que les poils usuels. The bristle represents, more particularly intended to garnish a toothbrush, can be used for all types of hygienic brushes since it can be mounted in the same way as the usual bristles.

Du point de vue de 1'hygiene, ce poil est absolu- ment aseptique etant donne que sa sterilisation est effectuee par 1e chauffage necessaire ä la formation du renflement 3. De plus, la manuten.tion et par consequent 1e risque de pollution sont reduits par 1e fait que laRTI ID="0001.0272" WI="15" HE="4" LX="1326" LY="1776"> formation du renflement et sa st6rili- sation sont simultanees. En outre, ce poil peut etre maintenu en etat de parfaite proprete, car la surface arrondie du renflement 3 n'offre pas de retention aux dechets et autres particules entraines par la brosse en cours d'utilisation. From the point of view of hygiene, this hair is absolutely aseptic since its sterilization is effected by the heating necessary for the formation of the bulge 3. In addition, the handling and consequently the risk of pollution are reduced. in that the RTI ID="0001.0272" WI="15" HE="4" LX="1326" LY="1776"> formation of the bulge and its sterilization are simultaneous. In addition, this hair can be kept in a state of perfect cleanliness, because the rounded surface of the bulge 3 does not offer retention to waste and other particles entrained by the brush in use.

Ce poil permet d'effectuer un massage des gen cives saus risque d'irritation ou de coupure et un polissage des dents sann attaquer l'esnail. This hair allows you to perform a massage of the gums without risk of irritation or cuts and a polishing of the teeth without attacking the esnail.
