Flushable Tampon Applicator

摘要

A tampon applicator that is water-sensitive (e.g., water-soluble, water-dispersible, etc.) in that it loses its integrity over time in the presence of water is provided. The tampon applicator can be discreetly disposed of in a toilet without the risk of clogging sewer pipes. The tampon applicator includes a molded thermoplastic composition containing a cellulose derivative, a synthetic water-soluble polymer, and a plasticizer. The desired water-sensitive characteristics of the tampon applicator may be achieved in the present invention by selectively controlling a variety of aspects of the thermoplastic composition from which the applicator is formed, such as the nature of the components employed, the relative amount of each component, the manner in which the composition is formed, and so forth.

主权项

1. A flushable tampon applicator, the tampon applicator comprising an outer tube for housing a tampon and comprising an inner tube, at least a portion of which extends into the outer tube, wherein the outer tube includes an outer, body-contacting surface, wherein the inner tube is moveable relative to the outer tube and configured to expel a tampon from the outer tube, further wherein at least one of the outer tube and the inner tube comprises a thermoplastic composition, the thermoplastic composition comprising:
a cellulose derivative; a synthetic water-soluble polymer; and a plasticizer; wherein at least one of the outer tube and the inner tube is a molded part.
