Abstract

A carrier mold having prongs that produces shaped tampons is provided. When subjected to pressure by a pushrod the prongs of the carrier mold flex to substantially or partially open one end of the carrier mold. A method of forming a shaped tampon using the carrier mold is also provided.

Claims (26)

1. A secondary sleeve and carrier mold combination comprising:

(a) a secondary sleeve having

(1) an inner surface, a pushrod end, and an evacuation end;

(2) wherein the inner surface defines an inner space having a diameter; and

(b) a carrier mold disposed within the secondary sleeve and having

(1) an outer surface, an inner surface, a first end, a second end opposite the first end, a body, and two or more prongs, each prong having a proximal base and a distal end;

(2) wherein at least one prong is in partial contact with at least one other prong;

(3) wherein the inner surface defines an inner cavity for producing shaped tampons; and

wherein the inner space of the secondary sleeve is capable of receiving the carrier mold and providing pressure to the two or more prongs of the carrier mold.

2. The carrier mold and secondary sleeve combination of claim 1 , wherein the diameter of the secondary sleeve inner space is less at the pushrod end than at the evacuation end.

3. The carrier mold and secondary sleeve combination of claim 1 , wherein the secondary sleeve inner surface includes a protuberance.

4. The carrier mold and secondary sleeve combination of claim 1 , wherein the secondary sleeve is a carrying member or a part of a drum.

5. A method of producing a shaped tampon comprising the steps of:

(a) providing a carrier mold having an outer surface, an inner surface, a first end, a second end opposite the first end, a body, and two or more prongs, each prong having a proximal base and a distal end; wherein at least one prong is in partial contact with at least one other prong; and wherein the inner surface defines an inner cavity having an open proximal end and an intermittently closed distal end;

(b) providing a secondary sleeve having an inner surface, a pushrod end, and an evacuation end, wherein the inner surface defines an inner space that provides pressure to the two or more prongs;

(c) inserting the carrier mold into the inner space of the secondary sleeve;

(d) transferring a pledget into the carrier mold inner cavity;

(e) providing a pushrod;

(f) contacting the pushrod with the first end of the carrier mold; and

(g) moving the carrier mold using the pushrod.

6. The method of claim 5 wherein, the diameter of the secondary sleeve inner space is less at the pushrod end then at the evacuation end.

7. The method of claim 6 , wherein the inner surface of the secondary sleeve completely or substantially stops the travel of the carrier mold, after the carrier mold has been inserted into the inner space of the secondary sleeve.

8. The method of claim 5 , wherein the two or more prongs flex to allow the pushrod to contact the shaped tampon.

9. The method of claim 8 , wherein the pushrod evacuates the shaped tampon from the carrier mold inner cavity.

10. The method of claim 9 , wherein the shaped tampon is stabilized prior to being evacuated from the carrier mold inner cavity.

11. The method of claim 5 , wherein the pledget is a compressed pledget.
