Claims22
A biodegradable tampon applicator comprising a molded, hollow cylindrical body of polymeric material enclosing a tampon therein and having a first flexible open end through which said tampon is expelled and a second open end for receiving means for expelling said tampon, said body comprising a moldable poly 3-hydroxybutyric acid composition.
A method for making a tampon applicator comprising employing a composition comprising a copolymer of 3-hydroxybutyric acid and 3-hydroxyvaleric acid residues and a plasticizer;
- the mol % of said 3-hydroxyvaleric acid residues and the quantity of plasticizer selected to result in said composition having a melt flow time of not more than 20 minutes and when molded to result in a material having a modulus of elasticity of 0.2 to 1.0 GPa molding said composition into a hollow cylindrical body, and inserting a tampon therein.
