Abstract: A toothbrush having an elongated handle provided at one end with a head comprising a surface from which bristles project in the usual manner. Within and extending longitudinally of the handle is an elongated cartridge chamber terminating at the head end of the handle with an opening communicating at one end with the chamber and at its other end with the bristled surface. The cartridge chamber is adapted to receive therein an elongated, tubular, flattenable, dentifrice cartridge insertable through an opening at the end of the chamber remote from the head. A dispensing member slidable longitudinally of and within the chamber is engageable with the cartridge to flatten such cartridge progressively from the remote end of the handle toward the head end thereof, thereby dispensing the dentifrice into the bristles of the toothbrush through an elastomeric, tubular cartridge tip disposed in the opening in the toothbrush head and extending beyond the bristled surface.

Abstract: A toothbrush having an elongated handle provided at one end with a head comprising a surface from which bristles project in the usual manner. Within and extending longitudinally of the handle is an elongated cartridge chamber terminating at the head end of the handle with an opening communicating at one end with the chamber and at its other end with the bristled surface. The smaller of the two angles between the opening and the bristled surface is no more than about 45.degree.. The cartridge chamber is adapted to receive therein an elongated, tubular, flattenable, dentifrice cartridge insertable through an opening at the end of the chamber remote from the head.
