ABSTRACT:
This invention relates to a tampon applicator. More particularly, this invention relates to an application system for hygienic introduction of a tampon which comprises a substantially cylindrical outer sleeve, a substantially cylindrical inner sleeve displaceable therein having an outer diameter substantially the same as the inner diameter of the outer sleeve and a flanged end, and a substantially cylindrical tampon, wherein (a) the front end of the outer sleeve is a conically rounded lamellar shutter means consisting of a ring of tulip-shaped lamellae abutting a circumferential groove acting as a hinge means, the shutter means being normally closed and opening during ejection of the tampon; (b) the outer sleeve consists of a high-gloss, plastic-coated paper, said paper being coated on the outer surface and said coated paper being readily water degradable or water dispersible; (c) the inner sleeve is comprised of water degradable or water dispersible paper; (d) the inner surface of the outer sleeve and the outer surface of the inner sleeve have co-efficients of friction such that they do not readily slide without applied pressure but on application of slight manual pressure readily slide, thus facilitating the opening of the lamellar shutter means and ejection of the tampon; (e) the outer sleeve has a grip in the form of a scoring; (f) said inner sleeve has substantially the same length as the outer sleeve; and (g) the outer sleeve, inner sleeve, and tampon form with the closed lamellar shutter means at the front end of the tampon a substantially closed system.
