Abstract
A fillable toothbrush provided with a handle containing a dispenser for toothpaste is disclosed. One end of the handle is provided with a stem through which a duct is provided from a storage chamber to an outlet adjacent to a brush arranged at the free end of the stem. An actuating element is provided at the end of the handle remote from the stem. When actuated, the actuating element moves a valve that closes off the storage chamber from the duct and pushes toothpaste through the duct to the brush. When the actuating element is released, the valve retracts and permits toothpaste in the storage chamber to flow into the duct. The dispenser toothbrush is of simple design and allows defined quantities of toothpaste to be dispensed in a reliable way.
Claims45
A dispenser toothbrush comprising a handle containing a storage chamber for toothpaste, one end of the handle being provided with a stem through which a duct leads from the storage chamber to a dispenser adjacent to a brush arranged at the free end of the stem remote from the storage chamber, a valve capable of closing off the storage chamber from the duct, and an actuating device provided at the other end of the handle which serves to actuate a means for altering the volume between the valve and the dispenser, the means being located between the storage chamber and the duct, the means and the valve being cooperatively arranged at said other end of the handle such that the valve closes only when the means is actuated, the duct running substantially the entire length of the dispenser toothbrush and being of sufficient narrowness such that the resistance to the flow of toothpast in the duct substantially prevents the flow of toothpaste from the dispenser to the storage chamber.
