Abstract
A tampon applicator has a barrel and a plunger telescopically mounted within the barrel. In a preferred embodiment, one or both of the barrel and plunger is made of a water dispersible material, and is exposed to a source of infrared radiation to minimize surface stickiness on initial contact with moisture. In an alternative embodiment, the barrel or plunger can be coated with a water dispersible material prior to exposure to infrared radiation.
Claims22
A tampon applicator comprising:
- a barrel having an outer surface and a first end, said barrel being made of a water dispersible material;
- and
- a plunger adapted to be telescopically mounted in the first end of said barrel,
- wherein said outer surface of said barrel is treated by infrared radiation to minimize surface stickiness on initial contact with moisture.
A tampon applicator comprising:
- a barrel having an outer surface and a first end, the outer surface of said barrel being coated with a water dispersible material;
- and
- a plunger telescopically mounted in the first end of said barrel,
- wherein said outer surface is treated by infrared radiation to minimize surface stickiness on initial contact with moisture.
A tampon applicator comprising:
- a barrel having an outer surface and a first end, said barrel being made of a water dispersible material;
- and
- a plunger telescopically mounted in the first end of said barrel, said plunger having an outer surface, said outer surface of said plungers being coated with a coating material comprising said water dispersible material,
- wherein said barrel and said plunger are exposed to infrared radiation prior to said tampon applicator being used, to minimize surface stickiness of said tampon applicator on initial contact with moisture.
A method for treating a tampon applicator barrel comprising the step of:
- subjecting a water dispersible outer surface of said barrel to a source of infrared radiation.
A method for treating a tampon applicator having a barrel and a plunger, comprising:
- subjecting said barrel and said plunger to a source of infrared radiation.
