toothpaste

1. Toothbrush (replaceable)

2. Housing (reusable cylinder)

3. Rotating piece (rotary handle)

4. Housing (disposable cylinder for toothpaste) or cartridge

5. Sliding piece (reusable piston in toothpaste cylinder 2).

Firstly, according to dentists' recommendations, the toothbrush should be replaced every 3 months at the latest, but this is only partially followed. There are toothbrush owners who cannot part with their old toothbrush. Some toothpaste tubes are only partially usable under the strain until they are emptied. Some screw caps can only be put on with care. The flap cap on toothpaste tubes (Colgate) breaks off easily before the tube is empty.

Some tubes break and partially dissolve before they are emptied. (Blend a med medic white)

Secondly, it is also inconvenient to have a toothbrush and toothpaste separate.

Thirdly, the common disposable toothpaste tubes, which are an oil product, consume a lot of unnecessary energy and also pollute the environment through their disposal.

If you buy a new toothbrush when you buy toothpaste, it will no longer be difficult to dispose of the used toothbrush. The toothpaste tube made of (pe - 07 etc.) can be replaced with an environmentally friendly cardboard cartridge.

Since the toothbrush should be replaced every three months, the toothpaste in the cartridge (4) is 50 ml - or two cartridges of 50 ml each, i.e. 100 ml for three months! The housing (2) of the toothbrush is made of white or transparent plastic, which is usually used for this purpose (as with electric toothbrushes).

An upwardly running spiral is incorporated into the housing (2) (inner cylinder wall).

In the white housing (2), this spiral is clearly visible from the outside due to its transparency, whereas in the transparent version, the advertising for the toothpaste used is also clearly visible. At the bottom of the housing (2) there is a removable rotating piece (3).

The spiral incorporated in the housing (2) moves the sliding piece (5) in the disposable cartridge (4) upwards towards the toothbrush (1) when the rotating piece (3) is turned clockwise.

This forces the toothpaste in the housing (4) through the tube in the toothbrush (1) to the brush head.

Advantage

The sliding piece (5) has a red guide knob on the lower and upper half, which moves the sliding piece (5) up or down in the housing (2) or (4) when it is turned. The guide knobs on the sliding piece (5) are clearly visible from the outside due to their red color, which means that the level or consumption of toothpaste can be easily read at any time.

The toothbrush (1), which needs to be replaced every 3 months, is replaced together with the toothpaste dispensing housing (4), which can be made of environmentally friendly cardboard.

The disposable housing (4) is inserted into the reusable housing (2) from below. The sliding piece (5) is then inserted into the housing (2) or (4). The cylinder (2) is now closed from below using the rotating piece (3), forming a toothed connection with cylinder (4) and a rotating connection with cylinder (2), which is released using pressure from the outside.
The toothbrush (1) is screwed into the upper end of the housing (2).

If the housing (2) is now held with the left hand and the rotating piece (3) is turned clockwise with the right hand, the sliding piece (5) in the housing (4) moves in the upward spiral in the housing (2) upwards towards the toothbrush (1), whereby the toothpaste in the disposable housing (4) is pressed through a tube in the toothbrush (1) to the brush head.

The advantage is that the used toothbrush is regularly replaced with a new one.

Because when you buy new toothpaste you also get a new toothbrush.

The environment is protected by using environmentally friendly cardboard.
