Patent ID: 8534950

Claim:
A toothbrush with integral toothpaste dispenser, comprising: a) a hollow handle portion and hollow replaceable brush portion having bristles held together by a screw threaded attachment; b) said hollow handle portion having a threaded bore with an open end at the top and an open end at the bottom; c) said bottom end of said handle portion receiving a turning knob attached to a vertical support tube with two lateral slots that engage with two posts of a pedestal; d) said posts of said pedestal pass through said two lateral slots of said vertical support tube and engage with said threaded bore of said handle, whereby when the knob is turned, the pedestal moves upwardly for clockwise rotation and downwards for counterclockwise rotation; e) a toothpaste tube containing toothpaste having a toothpaste exit cap removed and screwed into a threaded aperture of an end cap member that fits tightly on a distal end of said vertical support tube; f) said end cap member having an O-ring seal provided on a lateral cylindrical portion that engages with an open top end of the hollow handle; g) said toothpaste being delivered into a channel within said hollow interior of said toothbrush portion when the knob is turned in a clockwise direction to move the pedestal upwardly and thereby squeeze and progressively collapse said toothpaste tube; h) said toothpaste passing through said channel and being delivered between the bristles of the toothbrush portion through an aperture that is in close proximity with a non-return valve, and thereby creates a small space between a exit aperture and the non-return valve; and whereby the user determines how much toothpaste is delivered at the toothbrush bristles by turning the knob either manually or by electrical motor drive, the non-return valve automatically closes upon completion of toothpaste delivery and prevents drying out or spill of the toothpaste from the integral toothpaste dispenser, and the small space between toothpaste exit aperture to the brush bristles and the non-return valve ensures removal of toothpaste during rinsing, thereby providing a hygienically clean toothbrush.
