Abstract

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.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 136 words
An apparatus for intravaginally expelling an activated tampon comprising: a tampon storing member defining a chamber for receiving and storing therein said tampon in a quiescent unactivated state, said tampon being activated by a fluid; a reservoir member storing said fluid therein separate from and out of contact with said tampon; manually-activatable means for releasing said fluid from the reservoir member to activate the tampon with said fluid while the tampon is retained in said tampon storing member prior to intravaginal insertion; and means, including the structural cooperation of said tampon storing member and said reservoir member, for intravaginally expelling said tampon in its activated state from said apparatus into a vagina, wherein said fluid releasing means includes means for effecting fluid flow through a dispensing opening and a separate venting opening in said reservoir member.
Claim 2
Independent Claim 136 words
An apparatus for intravaginally expelling an activated tampon comprising: a tampon storing member defining a chamber for receiving and storing therein said tampon in a quiescent unactivated state, said tampon being activated by a fluid; a reservoir member storing said fluid therein separate from and out of contact with said tampon; manually-activatable means for releasing said fluid from the reservoir member to activate the tampon with said fluid while the tampon is retained in said tampon storing member prior to intravaginal insertion; and means, including the structural cooperation of said tampon storing member and said reservoir member, for intravaginally expelling said tampon in its activated state from said apparatus into a vagina, wherein said fluid releasing means includes means for effecting fluid flow through a dispensing opening and a separate venting opening in said reservoir member.
Claim 3
Dependent Claim 16 words
The apparatus of claim 1 wherein the means for effecting fluid flow includes an elongated element.
Claim 4
Dependent Claim 34 words
The apparatus of claim 2 wherein the reservoir member has an outer end wall and an inner end wall, and the elongated element extends from the outer end wall to the inner end wall.
Claim 5
Dependent Claim 52 words
The apparatus of claim 3 wherein the elongated element is movable with respect to the outer end wall and the inner end wall of the reservoir member to effect fluid flow through a dispensing opening in one of said end walls and a vent opening in the other of said end walls.
Claim 6
Dependent Claim 11 words
The apparatus of claim 1 wherein the fluid is a spermicide.
Claim 7
Dependent Claim 11 words
The apparatus of claim 1 wherein the fluid is a bactericide.
Claim 8
Dependent Claim 14 words
The apparatus of claim 1 wherein the fluid is a spermicide and a bactericide.
Claim 9
Dependent Claim 28 words
The apparatus of claim 4 wherein the elongated element includes a portion extending beyond one end wall of the reservoir member, said portion being grippable by a user.
Claim 10
Dependent Claim 24 words
The apparatus of claim 4 wherein the elongated element includes a sealing element forming a seal with one end wall of the reservoir member.
Claim 11
Dependent Claim 44 words
The apparatus of claim 4 wherein the elongated element includes two sealing elements, one sealing element forming a seal with one end wall of the reservoir member and the other sealing element forming a seal with the other end wall of the reservoir member.
Claim 12
Dependent Claim 20 words
The apparatus of claim 4 wherein the elongated element includes means for rupturing one end wall of the reservoir member.
Claim 13
Dependent Claim 13 words
The apparatus of claim 11 wherein the rupturing means includes a sharp edge.
Claim 14
Dependent Claim 34 words
The apparatus of claim 1 wherein the reservoir member is slidingly received in the tampon storing member so that the sliding movement of the reservoir member in the tampon storing member expels the tampon.
Claim 15
Dependent Claim 43 words
The apparatus of claim 12 wherein the inner wall of the reservoir member includes a flexible flange extending radially from the reservoir member into an annular groove in the tampon storing member, whereby the reservoir member is releasably held in the retracted position.
Claim 16
Independent Claim 145 words
An apparatus for intravaginally expelling an activated tampon from said apparatus comprising: a tampon storing member defining a chamber receiving and storing therein said tampon in a quiescent unactivated state, said tampon being activated by a fluid; a reservoir member defining a reservoir storing said fluid therein separate from and out of contact with said tampon; manually-activatable means for releasing said fluid from the reservoir member to activate the tampon with said fluid while the tampon is retained in said tampon storing member prior to intravaginal insertion; and means, including the structural cooperation of said tampon storing member and said reservoir member for intravaginally expelling said tampon in its activated state from said apparatus into a vagina, wherein said fluid releasing means includes a frangible wall in said reservoir member for defining a dispensing opening and a separate frangible element for defining a vent opening.
Claim 17
Independent Claim 145 words
An apparatus for intravaginally expelling an activated tampon from said apparatus comprising: a tampon storing member defining a chamber receiving and storing therein said tampon in a quiescent unactivated state, said tampon being activated by a fluid; a reservoir member defining a reservoir storing said fluid therein separate from and out of contact with said tampon; manually-activatable means for releasing said fluid from the reservoir member to activate the tampon with said fluid while the tampon is retained in said tampon storing member prior to intravaginal insertion; and means, including the structural cooperation of said tampon storing member and said reservoir member for intravaginally expelling said tampon in its activated state from said apparatus into a vagina, wherein said fluid releasing means includes a frangible wall in said reservoir member for defining a dispensing opening and a separate frangible element for defining a vent opening.
Claim 18
Dependent Claim 16 words
The apparatus of claim 15 wherein a grasping tab is provided on the separate frangible element.
Claim 19
Dependent Claim 11 words
The apparatus of claim 15 wherein the fluid is a spermicide.
Claim 20
Dependent Claim 11 words
The apparatus of claim 15 wherein the fluid is a bactericide.
Claim 21
Dependent Claim 14 words
The apparatus of claim 15 wherein the fluid is a spermicide and a bactericide.
