ABSTRACT:
The specification discloses a disposable toothbrush with a self-contained toothpaste supply comprising a transparent handle section and an adjustable brush head having upstanding bristles secured thereto.
The transparent cylindrical handle section is hollow and contains the dentifrice material, which is discharged into the adjustable head section when the handle section is compressed. The quantity of discharge of the dentifrice material can be easily measured and judged by the graduation marks placed on the handle. The adjustable brush head has a discharge opening for ejecting the dentifrice material between the bristles when the cylindrical transparent handle section is compressed. The adjustable brush head is capable of being closed so that premature or accidental discharge of the dentifrice material while either in storage or in use does not occur.
