Abstract
A disposable device for removing plaque and food debris from tooth surfaces, has a handle portion and a bow portion across which a length of dental floss is maintained, the floss, bow, and handle being an integral unit; and the method of manufacturing this complete device in essentially a single operation whereby the handle and bow are molded with the ends of the length of floss disposed and secured in ends of the bow during molding.
Claims6
A method of making from fluid plastic a solid flosser having a handle part and extending therefrom two arms spaced apart with a strand of floss having a central part spanning the space between said arms and having end-parts embedded within said arms, the method comprising forming a mold and cavity therein defining handle and arm parts corresponding closely to said handle and arm parts of said flosser, positioning the central part of a strand of floss to span the space between said arms of the cavity and said end parts to traverse said arms of the cavity prior to flowing fluid plastic therein, flowing fluid plastic into said cavity by an injection molding process, and thereby embedding with plastic said end parts of the strand in said arm parts of the cavity, and thus coating with said plastic substantially the entire outer peripheral surface of said end-parts, hardening said fluid plastic and thereby in substantially a single step forming said solid flosser and securing said floss end-parts in and integrally with the flosser's arm parts.
A method of making from fluid plastic a solid flosser having a handle part and at least two spaced-apart floss-engaging portions with a strand of floss having a central part spanning the space between said floss-engaging portions and end-parts of the strand embedded within said floss-engaging portions, comprising forming a mold and cavity therein defining handle and floss-engaging portions corresponding closely to said handle and floss-engaging portions of said flosser, positioning the central part of a strand of floss to span the space between and to traverse said floss-engaging portions of the cavity prior to flowing fluid plastic therein, flowing fluid plastic into said cavity by an injection molding process, and thereby embedding with plastic said end parts of the strand in said floss-engaging portions of the cavity, and thus coating said plastic on substantially the entire outer peripheral surface of said end-parts of the strand of floss, hardening said fluid plastic, and thereby forming said solid flosser and securing said floss end-parts within and integrally with the flosser's floss-engaging portions.
