Abstract
An oral hygiene device is disclosed. A toothbrush attached to a case or cartridge that works as a handle and contains toothpaste in its interior. To allow inner, fast and automatic toothpaste flow on the toothbrush bristles, a button (stopcock) located on the top of the case or cartridge has to be pushed down. Upon releasing the stopcock, toothpaste flow stops. The longer the stopcock is held down, the larger amount of toothpaste will flow on the bristles.
Claims3
A toothpaste dispensing toothbrush comprising:
- a container unit, a stopcock unit, and a brush unit;
- said container unit having a cartridge containing pressurized toothpaste;
- said cartridge further having a first end and a second end;
- said first end being sealed with a cover having an opening and said second end being closed with an adjusting cap;
- said adjusting cap consisting of a bottom, a top and a conical spring in between of the bottom and the top;
- and
- said spring being in a compressed state when the container is full of toothpaste and being in rest state when the container is empty;
- the stopcock unit comprising a case, a vertical hatch, a conical spring, and two horizontal ducts,
- said case having four vertical walls and two horizontal walls;
- said vertical hatch having an upper end, a lower end and a central part;
- said upper end protruding out of a horizontal wall of the case and forming a button,
- and said lower end standing on the conic spring;
- said hatch further having an opening in the central part;
- said horizontal ducts having same diameter as the opening of the hatch, and said ducts having first ends and second ends;
- said first ends locating at the hatch below the opening, and said second ends protruding out of two opposite vertical walls of the case;
- the brush unit comprising a toothbrush with a horizontal duct;
- said duct having a first end and a second end;
- the first end leading to bristles of the brush and the second end having a diameter similar as the ducts of the stopcock unit;
- said brush unit being attachable to one vertical wall of the case of the stopcock unit where one of the horizontal ducts protrudes the wall, and said container unit being attachable from its first end to the opposite vertical wall of the case of the stopcock unit where the second duct protrudes;
- said button providing a means to lineate the horizontal ducts and the hatch opening in the cockstop unit by compression of the conic spring, whereby the pressurized toothpaste freely flows from the cartridge via the opening of the cartridge cover, through the cockstop ducts into the duct of the brush unit.
