Abstract
Abstract A tampon applicator is provided with an inner and an outer sleeve. The inner sleeve extends slightly beyond the outer sleeve when the sleeves are mated and is only slightly longer than the tampon for which the applicator is designed to deliver. In one embodiment, the inner sleeve has a series of slots tapering inward and downward from the forward end which are designed to engage injection guides located on the inner surface of the outer sleeve near the base.

Claim 1
Independent Claim
178 words
A tampon applicator comprising in combination: an outer tube, having: a forward end for delivery of a tampon; a rearward end with an open base for receiving an inner tube; an inner surface; and injection guide means on said inner surface tapering inwardly longitudinally toward said forward end of said outer tube from an area substantially at said base to a situs slightly above said base; and an inner tube of substantially the same length of the outer tube and the tampon to be inserted by said applicator for slidable mating in said outer tube said inner tube having: a forward end and a rearward end corresponding to the forward and rearward ends of the outer tube when mated; and a radially compressible means at least at the forward end of said inner tube compressed by said injection guide means during withdrawal of the inner tube from the outer tube, comprising a pair of inwardly and downwardly tapering slots at either side of said flanges, said slots having stops located near the rearward edge of the inner tube.
