Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the work of applying toothpaste to a toothbrush at the beginning of the toothbrushing process used to prevent cavities, etc., and it is possible to efficiently and reliably apply toothpaste to a toothbrush. It has been made possible to implement.

In the conventional toothbrushing process, toothpaste was pressed onto the toothbrush each time it was used, and the toothpaste was deposited on the brush surface. It is a particularly difficult task, and it often happens that the toothpaste cannot properly adhere to the brush surface, resulting in neglecting the toothbrushing task.Also, even ordinary people tend to adhere toothpaste to the brush surface. I often end up dropping toothpaste from my brush while working.

Therefore, the present invention has been made to reliably eliminate the above-mentioned drawbacks, and one embodiment shown in the drawings will be explained in detail below. A plurality of 10 toothpaste removal holes are also provided between the brushes of 8 brushes, and 6 on-off valve mechanisms for removing toothpaste are provided in 1.
The opening/closing valve mechanism of 6 is housed inside the brush body of 9.
By pushing out or pulling back the on-off switch 9 with the fingertip of 11, the toothpaste removal hole 10 is opened and closed. Press into the hole 1
7 is a leaf spring to prevent the toothpaste from flowing out from the internal toothpaste retention chamber in 2. 2 is a grip of the toothbrush, and the cartridge 3 is housed inside this grip. 5 is a spring for extruding 3. The purpose of this cartridge-type toothbrush is to push out the toothpaste sealed in the cartridge 4, and it is installed in the grip of the toothbrush 2.
Remove the grip of the toothbrush (2) with the open/close switch (9) in the closed position, insert the cartridge (3) containing the toothpaste (4) into the socket (13) of the brush body (1), and attach the cartridge (5). The grip part of the toothbrush (2), which is equipped with a push-out spring, is assembled with the brush body (1) to push out toothpaste (4) from the cartridge (3). Fig. 2 shows the opening/closing switch (9). In this case, the toothpaste 4 sealed in the cartridge 3 (not shown) flows out through the toothpaste retention chamber 12 and into the toothpaste removal hole 10. Since the toothpaste that flows out gets into the spaces between the brushes 8, it does not fall off and the toothpaste can be reliably attached to the brushes.In this way, the present invention is useful for applying toothpaste to toothbrushes, which is done every day. can be applied easily and reliably with one hand, has a simple structure and device, and has the advantage of being easy to use by any person, and has great practical effects.
