Toothpaste dispensing toothbrush having a squeezable handle

Claim 1

A dentifrice dispensing toothbrush comprising: a brush head unit including a hollow shaft having, at one end, discharge vents and a plurality of bristle members extending radially outwardly therefrom and being of reduced diameter at its opposite end and terminating in a pointed tip; a hollow toothpaste container of corresponding diameter including a rigid tubular wall at one end defining an orifice and being threaded on its inner periphery and threadably receiving the reduced diameter portion of said hollow shaft; an integral, transverse membrane wall pierceable by the pointed tip of the hollow shaft; and a deformable wall extending axially beyond said membrane wall oppositely to said orifice chamber; and wherein said toothpaste container rigid wall comprises an annular collar projecting radially outwardly therefrom; and a removable semi-rigid outer case surrounding the toothpaste container and having an opening within one end of a diameter slightly in excess to the outer diameter of said toothpaste container, but less than the diameter of said annular collar; whereby, said removable semi-rigid outer case slidingly receives said toothpaste container with said annular collar inwardly of said opening, said outer case being equipped with an atmospheric vent and said case being constructed such that pressure on said case will cause deforming of the outer wall of the toothpaste holding chamber forcing toothpaste through said hollow shaft and outwardly of said discharge vent at the base of said bristle members.
