Multiple-component tampon applicator
View Patent ↗A method of making a tampon applicator having four separable components includes forming a barrel having a forward end and a rearward end opposite the forward end, forming a fingergrip having a barrel end and a plunger end, where the fingergrip has an axially extending channel between the barrel end and the plunger end and the plunger end has a cross-sectional area that is less than a cross-sectional area of the barrel end, forming an insertion tip having a first end and a second end, forming a plunger having a forward end, connecting the barrel end of the fingergrip with the rearward end of the barrel, where the barrel end of the fingergrip and the rearward end of the barrel create a continuous surface flush with the barrel when connected, connecting the second end of the insertion tip to the forward end of the barrel, and inserting the forward end of the plunger into the channel of the fingergrip.
1. A method of making an applicator having four separate components comprising the steps of
(a) forming separately in any order:
(1) a barrel having a tubular shape and having a forward end and a rearward end opposite said forward end, said forward end having an innermost surface and an outermost surface with an outermost diameter, said innermost surface and said outermost surface forming a forward end surface therebetween;
(2) a fingergrip having a barrel end and a plunger end, said plunger end having a cross-sectional area that is less than a cross-sectional area of said barrel end;
(3) an insertion tip having a first end and a second end, said insertion tip having a plurality of petals that taper toward said first end to form a conical shape, said plurality of petals being connected at said second end, said second end having an inner surface and an outer surface, and said inner surface and said outer surface forming an end surface therebetween;
(4) a plunger having a forward end; and
then (b) inserting a tampon pledget into said barrel;
(c) connecting said barrel end of said fingergrip to said rearward end of said barrel;
(d) connecting said end surface of said insertion tip to said forward end surface of said barrel; and
(e) inserting said forward end of said plunger into said plunger end.
2. The method of claim 1 , wherein one or more of said four separate components are formed from a material selected from the group consisting of biopolymer, cardboard, heat shrink plastic, paper slurry, plastic, plastic tubing, pulp slurry, pulp-molded paper, and any combinations thereof.
3. The method of claim 1 , wherein two or more of said four separate components are formed from a material selected from the group consisting of biopolymer, cardboard, heat shrink plastic, paper slurry, plastic, plastic tubing, pulp slurry, pulp-molded paper, and any combinations thereof.
4. The method of claim 1 , wherein three or more of said four separate components are formed from a material selected from the group consisting of biopolymer, cardboard, heat shrink plastic, paper slurry, plastic, plastic tubing, pulp slurry, pulp-molded paper, and any combinations thereof.
5. The method of claim 1 , wherein at least one of said four separate components is coated with a material selected from the group consisting of cellophane, cellulose, epoxy, lacquer, nitrocellulose, nylon, plastic, polyester, polylactide, polyolefin, polyvinyl alcohol, polyvinyl chloride, silicone, wax, and any combinations thereof.
6. The method of claim 1 , wherein said plurality of petals comprises three to eight petals.
7. The method of claim 1 , wherein said fingergrip further comprises at least one gripping structure.
8. The method of claim 7 , wherein said at least one gripping structure is circumferentially disposed around said fingergrip.
9. The method of claim 7 , wherein said at least one gripping structure is selected from the group consisting of one or more abrasive materials, embossments, grooves, high wet coefficient of friction materials, lances, pressure sensitive adhesives, protuberances, slits, treads, and any combinations thereof.
10. The method of claim 7 , wherein said at least one gripping structure is formed in a shape selected from the group consisting of arc, circle, concave, cone, convex, diamond, line, oval, polygon, rectangle, rib, square, triangle, and any combinations thereof.
11. The method of claim 7 , wherein said at least one gripping structure is raised above, depressed below, or a combination thereof, a surface of said barrel.
12. The method of claim 1 , wherein said barrel end of said fingergrip has an external cross-sectional area slightly larger than that of an internal cross-sectional area of said rearward end of said barrel, and wherein said fingergrip and said barrel are connectably secured by interference fit.
13. The method of claim 1 , wherein said barrel end has a fingergrip inner surface and a fingergrip outer surface, said fingergrip inner surface and said fingergrip outer surface forming a fingergrip end surface therebetween, wherein said fingergrip end surface has a connector ring, wherein said connector ring has an outer surface and an inner surface extending from said fingergrip end surface and said outer surface and said inner surface have an end wall therebetween, wherein said outer surface of said connector ring has a cross-sectional area slightly smaller than an external cross-sectional area of said rearward end of said barrel, and wherein said connector ring and said barrel are connectably secured by interference fit.
14. The method of claim 1 , wherein said barrel end of said fingergrip further comprises one or more external tabs, ridges, slots, and any combination thereof, for securably connecting said fingergrip to said barrel.
15. The method of claim 1 , wherein said barrel end of said fingergrip further comprises one or more internal tabs, ridges, slots, and any combination thereof, for securably connecting said fingergrip to said barrel.
16. The method of claim 1 , wherein said rearward end of said barrel further comprises one or more external tabs, ridges, slots, and a combination thereof, for securably connecting said barrel to said fingergrip.
17. The method of claim 1 , wherein said rearward end of said barrel further comprises one or more internal tabs, ridges, slots, and a combination thereof, for securably connecting said barrel to said fingergrip.
18. The method of claim 1 , wherein said forward end of said barrel further comprises one or more tabs, ridges, slots, and any combination thereof, for securably connecting said barrel to said insertion tip.
19. The method of claim 1 , wherein said second end of said insertion tip further comprises one or more tabs, ridges, slots, and any combination thereof, for securably connecting said insertion tip to said barrel.
20. The method of claim 1 , wherein said fingergrip is formed from heat-shrinkable material having a diameter larger than a diameter of said barrel, and wherein said heat-shrinkable material is shrunk to securably fit over an outside surface of said barrel.
21. The method of claim 20 , wherein said heat-shrinkable material is further shrunk at said plunger end of said fingergrip to form a reduced cross-sectional area.
22. The method of claim 20 , wherein said connecting said barrel end of said fingergrip with said rearward end of said barrel occurs prior to inserting said pledget into said barrel, and wherein said connecting said second end of said insertion tip to said forward end of said barrel occurs subsequent to said inserting said pledget into said barrel.
23. The method of claim 20 , wherein said connecting said barrel end of said fingergrip with said rearward end of said barrel occurs subsequent to inserting said pledget into said barrel, and wherein said connecting said second end of said insertion tip to said forward end of said barrel occurs prior to said inserting said pledget into said barrel.
