ABSTRACT:
An apparatus for moistening a tampon with a spermicidal, bactericidal and/or virucidal fluid and expelling the tampon includes an open ended tampon storing member for storing the tampon in an unactivated state and a reservoir member for storing the fluid. The reservoir member has a closed inner end slidably received in the tampon storing member and a closed outer end extending out of the tampon storing member. In several embodiments, the reservoir member includes an elongated element to effect fluid flow through a dispensing opening in the inner end and through a vent opening in the outer end. In another embodiment, the inner end of the reservoir member is closed by a wall which is fragible under radially applied pressure to form a dispensing opening and the other end is closed by a wall having an element which is frangible to form a vent opening.
