Toothbrush with removable attachment

Abstract

A toothbrush is proposed which has a removable attachment comprising a body with a longitudinal slot and, arranged in the longitudinal slot, a removable attachment having clumps of brush bristles fastened therein. The body is in the form of a flat elongated piece and includes two parts: a main part with a central longitudinal opening and a locking part, which is inserted into and is locked in the central longitudinal opening of the main part. The edges of the base of the removable attachment are slanted in the longitudinal direction at an acute angle. Moreover, on the transverse vertical wall of the slot which is outermost from the centre of the toothbrush there is a projection and on the transverse vertical wall of the removable attachment there is a recess which corresponds to the projection of the slot. Furthermore, in the removable attachment there is a longitudinal opening into which the end part of the locking part of the body is inserted.

I claim: 
     
         1 . A toothbrush with a removable nozzle, containing a body with a longitudinal groove, and placed in the longitudinal groove, a removable nozzle with bundles of bristle fibers fixed in it, characterized in that the body is made in the form of a flat elongated body and includes two parts: the main part with a central longitudinal hole and a locking part that enters and is fixed in the central longitudinal hole of the main part, the edges of the base of the removable nozzle are longitudinally beveled, in addition, a protrusion is made on the transverse vertical wall of the groove, which is extreme from the center of the toothbrush, in the central part, and on the transverse vertical wall of the removable nozzle there is made a recess corresponding to the protrusion of the groove, while the removable nozzle has a longitudinal hole into which the end part of the locking part of the body enters. 
     
     
         2 . The toothbrush according to  claim 1  characterized in that the body is made in the form of a long and narrow parallelepiped with a small height, in which the extreme vertical faces are a semicircle in cross section. 
     
     
         3 . The toothbrush according to  claim 1 , characterized in that above the beveled base of the removable nozzle closest to the center of the toothbrush there is a platform free from bundles of bristle fibers. 
     
     
         4 . The toothbrush according to  claim 1 , characterized in that the edges of the base of the removable nozzle are longitudinally beveled at an acute angle or along a radius. 
     
     
         5 . The toothbrush according to  claim 1 , characterized in that the junction of the main part and the locking part, which is fixed in the main body part, is made beveled at an acute angle. 
     
     
         6 . The toothbrush according to  claims 1 ,  4 , characterized in that the locking part includes a protrusion, and the main part includes a recess corresponding to the protrusion of the locking part, while in the lock part, closer to the protrusion, a longitudinal groove is made for elastic connection and fixation in each other of said protrusion and said recess.
