<p>The toothpick comprises one or more flat working ends (1) and a body (2), formed from a single section cut out from a sheet of strong flexible material such as cellulose or plastic and of constant thickness. The body is of at least double the thickness of the working ends, and is formed by rolling or pref. folding part of the section cut out over against itself. The layers forming the body can be secured together by strong non-toxic glue, and the material used can have a constant thickness of roughly 0.3mm. It can be cut out from the plastic material used to form supports for radiography films.</p> |
