Title (EN) SAND-GLASS, IN PARTICULAR FOR INDICATING THE DURATION OF BRUSHING OF THE TEETH
(FR) SABLIER, NOTAMMENT POUR INDIQUER LA DUREE DU BROSSAGE DES DENTS
Abstract:
(EN) A sand-glass is provided at least on the front with a cover depicting a face. The cover has a tooth-shaped recess arranged at a height above the base of the sand glass such that the recess is only covered by sand when all the sand has run through the sand-glass. The sand-glass is particularly suitable for indicating to children the course and end of the minimum duration for brushing of the teeth.
(FR) Un sablier est pourvu au moins sur sa face antérieure d'un couvercle représentant un visage. Le couvercle comprend un évidement ayant la forme d'une dent agencé à une telle distance du fond du sablier qu'il n'est complètement recouvert de sable que lorsque tout le sable s'est écoulé dans le sablier. Le sablier convient en particulier pour indiquer à des enfants le déroulement et la fin de la durée minimale du brossage des dents.
