A handle for a mouth was device includes a switch for selectively connecting the liquid intake with a canal having bristleless a single-jet spray or with a canal having a bristleless multi-jet spray.

Handle for a mouth wash device

The present invention relates to a method for rounding the bristle tips of toothbrushes by the action of laser radiation, characterized in that the rounding process is effected in an electrostatic field, thus avoiding the fusion of the individual bristles as well as the formation of a mushroom-like bristle tip.

Process for rounding the bristle tips of toothbrushes and toothbrushes

A toothbrush having a brush handle and brush head is provided with a plurality of openings in the brush head for receiving therein bundles of bristles. Each of the plurality of openings is in the shape of a hexagon having parallel elongated sides and rounded opposing ends. The plurality of hexagonal openings are also of a substantially uniform depth to evenly receive the bristle bundles.

Toothbrush

The invention relates to an electrically operated toothbrush with oscillating motion, whose angle of oscillation can be adjusted. This is a easily achieved by the fact that the rotation of the electric motor producing the motion can be reversed by pole changing, and thereby the radius of the circular orbit of the bolt of a rotating shaft connected to the holder taking up the slip-on brush in a curve-like opening of a free disc is changed in its dimension, thus producing a variation of the angular deflection of the rotating shaft.
