Abstract

The tooth-brush has a curved handle (1), a long, thin and rounded intermediate piece (2), and head (3) which is at right angles to the axis of the brush and has tufts of bristles (4) regularly spaced out over the flat surface of the head on a plane parallel to that of the handle (1). The head is roughly oval, and has a notch where it joins the intermediate piece (2). The handle has undulations the size of which increase towards the end.

Description

La présente invention concerne une brosee a dents.The present invention relates to a toothbrush.

Elle appartient a la catégorie des brosses a dents classiques faites en principe en matiere plastique par injection.It belongs to the category of classic toothbrushes made in principle of plastic by injection.

L'invention se distingue par rapport aux autres dans cette catégorie en ayant comme caractéristique principale la tête montee pérpendiculairement au manche de forme lewgerement arqué.The invention is distinguished from the others in this category by having as main characteristic the head mounted perpendicularly to the slightly arched handle.

Ceci est une amélioration quant au brossage des surfaces intérieures et des espaces intercalaires de dents. Les brosses a dents existantes semblent moins efficaces dans ce domaine.This is an improvement in brushing the interior surfaces and the spaces between the teeth. Existing toothbrushes seem less effective in this area.

L'invention(PIG 1),de longueur comprise entre 13 et 17 cm,com- porte une tête sensiblement ovale (3) dont la partie supérieure est semi-arrondie, selon la coupe (AA) vue de face (FIG.2), et qui comporte un décrochement (5) a la jonction avec le col (FIG3), pour eloigner le manche de la surface de brossage. Dimensions de la tête de brosse se situent entre 2 a 2,5 cm (a) et 1 a 1,5 cn (b) F1G.3. The invention (PIG 1), of length between 13 and 17 cm, comprises a substantially oval head (3) whose upper part is semi-rounded, according to the section (AA) viewed from the front (FIG. 2) , and which includes a recess (5) at the junction with the neck (FIG3), to move the handle away from the brushing surface. Brush head dimensions are between 2 to 2.5 cm (a) and 1 to 1.5 cm (b) F1G.3.

En position pérpendiculaire par rapport i l'axe du col (2) la tête assure ainsi un brossage plus efficace par sa double action s'exerçant simultanément sur les surfaces des dents supérieures et inidrieures et pernet un brossage plus radieal des surfaces intérieures et exterieures de dent. de devant tout en minimi- sant le désagreable contact avec le palais. Les touffes de poils (4) son implantées régulièrement sur la surface plate de la tete de la brosse disposée dans un plan sensiblement parallele au plan du manche. L'invention comporte un manche rond et ondulé(1) consistant en boules d'environ 1,7cm de # et dininuant progres- sivement pour atteindre un QI de 1,2cm environ vers le col (2).In the perpendicular position relative to the axis of the neck (2) the head thus ensures more effective brushing by its double action acting simultaneously on the surfaces of the upper and inner teeth and allows more radieal brushing of the interior and exterior surfaces of tooth. from the front while minimizing unpleasant contact with the palate. The tufts of bristles (4) are regularly implanted on the flat surface of the head of the brush arranged in a plane substantially parallel to the plane of the handle. The invention comprises a round and wavy handle (1) consisting of balls of approximately 1.7 cm of # and gradually decreasing to reach an IQ of approximately 1.2 cm towards the neck (2).

Le relief du manche en forme ondulée apporte une neilleure prehension. Le col (2) long , mince et orrondi apporte par sa legère courbe une souplesse de manipulation et se termine par une tête de brosse.The relief of the wavy handle provides a better grip. The long, slender, rounded neck (2) provides flexible handling with its slight curve and ends with a brush head.
