ABSTRACT:
A flow-controlling tampon, comprising, in combination a generally upright insertion tube having upper and lower ends, and a plunger within said tube and manipulable proximate the tube lower end; flow receiving structure positioned within the tube to be bodily displaced and to protrude from the upper end of the tube in response to the manipulation of the plunger, the flow receiving structure having an upper end portion configured to expand to extend about the cervix in response to upward bodily displacement of the flow receiving structure effected by the plunger; and removal structure associated with the upper end portion of the receiving structure to effect contraction thereof when the receiving structure is withdrawn away from the cervix. The flow receiving structure typically includes flow absorbent material contained within a thin moisture resistant sheath having an expansible upper end that is contracted by pulling on strand structure.
