 I1 consists in fact of the manufacture of a toothbrush comprising two parts: the "head", carrying the bristles useful for brushing, implanted on a base provided with a hollow conduit perforated with three holes, against the external tip protruding the "head" of the brush is provided with a casing, preferably "Clips" (registered trademark), and the "handle" also can be of a conduit with at the outset a casing corresponding to that of the end of the conduit the "head", and ending in a cavity forming a flexible blister on the top of the handle. This blistered cavity, as well as the conduit, are sealed and filled with a dose of toothpaste used for brushing.

 When the user brings the two parts together, by penetrating, with less pressure, the duct protruding from the "head" into the inner duct of the "handle", and presses on the flexible blister, the toothpaste spreads on the hairs. the "head" of the toothbrush by their base thus allowing complete brushing of the teeth.

 The device can be made of plastic, in two injection molding operations, the bristles of the brush being made of synthetic material.

The accompanying drawings illustrate the invention
Figure I shows in section the device
according to the invention,
Figure 2 shows in section part of the
device according to the invention called: "head",
Figure 3 shows in section part of the
device according to the invention called: "handle".

 The part of the device called "head", represented in FIG. 2 comprises the base (I), carrying the bristles (2) 9 mm high, having dimensions of the order of one centimeter for 1 width, of 2, 5 centimeters for the length and 5 millimeters for the thickness. In one of the small lateral faces of the base, a conduit (3) provided at the end of a socket, preferably "Clips" (4) has a length of 2.5 centimeters and a diameter of one millimeter. This conduit (3) is positioned so as to extend beyond the base (I) by one centimeter and has three holes (5), one millimeter each in diameter, allowing passage of the toothpaste.

 The part of the device called "handle", represented in @a FIG. 3 comprises the "handle" proper (6) with a length of 9 centimeters, a width of one centimeter and a thickness of 5 millimeters. In one of the small side faces of the "sleeve @, a hollow and sealed inner conduit (7), also provided with a socket (s) matching that of the conquest of the" head "(4) ends by a cavity (9) forming a blister (IO) on the top of the "@anche" (6). The inner duct (7) as well as the cavity (o) forming the blister (ICss are filled with toothpaste.

 The device according to the invention shown in Figure I assembles the "head" to the "handle" and forms the ready-to-use toothbrush. A pressure on the blister (9) makes it possible to propel the dose of toothpaste through the holes (5, of the conduit (3) of the "head", the toothpaste then spreading through the base of the bristles (2) of the toothbrush .

 he device according to the invention is intended for the use of any human being.
