Description:

This invention is a toothbrush that has the toothpaste integrated into the handle and that dispenses the toothpaste under the bristles when in use.

The problem still lies in applying the toothpaste or in saving on packaging and simplifying it.

The state of the art is: in the utility model G 93 04 313.9, 0 437 706 Al of the Colgate Palmolive Company and the dispenser for toothpaste (file number unknown). The novelty lies in the fact that the dispenser and toothbrush are one and thus neither a tube nor a dispenser are needed. This toothbrush can be refilled after it has been emptied. This invention could save huge mountains of rubbish.

After use, the toothbrush is rinsed as usual and closed with a preferably transparent plastic cover which has a small ventilation hole on the brush head. The brush can be placed vertically on the base of the brush, just like the conventional dispenser. After emptying the brush, the piston, which is then located in the upper part of the cylinder and has an eyelet on the bottom, is pulled out completely using a plastic rod. After this step, the refill cartridge, which is preferably made of cardboard, is attached and the piston is placed on the other end of the cartridge. The piston is now pressed into the cylinder using the plastic rod, whereby the actuation button must be open.

Description/Reference:

The toothbrush has a capacity of approximately 75ml, i.e. the same volume as a normal tube. To use it, the operating button (4) is pressed down, which acts on the pump mechanism, whereby the toothpaste is compressed and escapes through the opening in the operating button (9) to the riser tube (3) and comes out at the outlet openings (19) under the bristles. The movable piston (8) which is located in the cylinder and has an integrated membrane (14) ensures the necessary pressure for compression.
