Abstract
A fountain toothbrush including an elongated tubular housing with a tubular insert held captive therein for receiving toothpaste with a brush head attached to the discharge end thereof and a mechanism associated with the opposite end for causing the toothpaste to be discharged upon rotation of an operating knob with the structure of the insert including a barrier to passage of moisture from the toothpaste to the atmosphere and a barrier to passage of air or oxygen from the atmosphere to the toothpaste thereby maintaining the toothpaste in a hygienic condition with the viscosity thereof also being maintained at a desired level for optimum discharge characteristics of the toothpaste to the bristles on the brush head.
Claims13
A fountain toothbrush comprising a housing of elongated cylindrical configuration, a cylindrical insert means in said housing for receiving toothpaste and forming a barrier to migration of moisture and air in relation to the toothpaste therein, a brush head connected to one end of said housing and insert means, said brush head including a plurality of bristles thereon, a passageway extending from the bristles to the insert means for guiding toothpaste onto the bristles, and insert means in said way forming a barrier to migration of moisture an air in relation to the toothpaste in the passageway, and closure means for the passageway where it communicates with the bristles to form a sealed container for the toothpaste, said insert means being captively retained in the housing and passageway, said housing including a generally cylindrical neck having an internal flange therein, said insert means in said housing including a threaded neck formed by plastic material encapsulating a portion of the insert means and a shoulder at the inner end of the threaded neck engaged with the flange on the housing, said brush head including an internally threaded end portion engaged with the threaded neck of the insert means in the housing and in captive engagement with the opposite side of the flange from the shoulder thereby securing the brush head, housing and housing insert means together in assembled relation.
A fountain toothbrush comprising a housing of elongated cylindrical configuration, insert means captively retained in said housing for receiving toothpaste and forming a barrier to migration of moisture and air in relation to the toothpaste therein, and a brush head connected to one end of said housing and insert means, said brush head including a plurality of bristles thereon, a passageway extending from the bristles to the insert means for guiding toothpaste onto the bristles, and closure means for the passageway where it communicates with the bristles to form a sealed container for the toothpaste, said housing including a generally cylindrical neck having an internal flange therein, said insert means including a threaded neck extending through the flange and including a shoulder at the inner end thereof engaged with the flange, said brush head including an internally threaded end portion engaged with the threaded neck of the insert means and engaged with the opposite side of the flange from the shoulder thereby captively securing the insert means in the housing.
A fountain toothbrush comprising an elongated housing, a brush head with bristles thereon extending from one end of said housing, said brush head including a passageway therein communicating the interior of the housing with the bristles, tubular insert means in said housing for receiving toothpaste, said insert means in the housing including an open end communicating with the passageway in the brush head, tubular insert means in said passageway communicating with the open end of the insert means in the housing, closure means on said brush head for closing the passageway where it communicates with the bristles, each of said insert means being constructed of material forming a barrier to migration between the toothpaste and said housing and brush head with the adjacent ends of the insert means being engagingly associated to form a continuous barrier.
