Abstract
Abstract A tampon assembly including an outer tube and an inner tube telescoped into the outer tube, with a tampon body of elastomeric sponge material in the outer tube and expelled therefrom by means of the inner tube. A sheath of thin flexible low-friction material is disposed between the tampon body and the outer tube to facilitate the expulsion of the tampon body from the outer tube. The tampon body may be formed within a mold having inwardly extending spike-like projections on its inner surface to provide fluid passing openings on the exterior surface on the tampon body.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
114 words
A tampon assembly comprising an outer tube, a fluid absorbing tampon body within said tube and adapted to be expelled out of said outer tube, and a sheath of thin sheet material disposed between at least a part of the outer surface of said tampon body and the inner surface of said outer tube, said sheath being separate of said outer tube and tampon @on body and having a greater frictional engagement with said tampon body than with aid outer tube so that, as the tampon body is expelled out of said outer tube, the sheath travels with said tampon body and facilitates the movement of the tampon body out of the outer tube.
Claim 2
Dependent Claim
114 words
A tampon assembly comprising an outer tube, a fluid absorbing tampon body within said tube and adapted to be expelled out of said outer tube, and a sheath of thin sheet material disposed between at least a part of the outer surface of said tampon body and the inner surface of said outer tube, said sheath being separate of said outer tube and tampon @on body and having a greater frictional engagement with said tampon body than with aid outer tube so that, as the tampon body is expelled out of said outer tube, the sheath travels with said tampon body and facilitates the movement of the tampon body out of the outer tube.
Claim 3
Dependent Claim
43 words
A tampon assembly as set forth in claim 1, said tampon assembly also comprising an inner tube telescoped within said outer tube and arranged to expel said body from said outer tube when the inner tube is moved farther into said outer tube.
Claim 4
Dependent Claim
43 words
A tampon assembly as set forth in claim 1, said tampon assembly also comprising an inner tube telescoped within said outer tube and arranged to expel said body from said outer tube when the inner tube is moved farther into said outer tube.
Claim 5
Dependent Claim
40 words
A tampon assembly as set forth in claim 2, said tampon body being made from an elastomeric sponge material and being of greater diameter than the inner diameter of said outer tube when the tampon body is in free condition.
Claim 6
Dependent Claim
20 words
A tampon assembly as set forth in claim 3, said sheath overlying the complete outer surface of said tampon body.
Claim 7
Dependent Claim
26 words
A tampon assembly as set forth in claim 3, said sheath extending around said tampon body and overlapping the tampon body with a pair of flaps.
Claim 8
Dependent Claim
54 words
A tampon assembly as set forth in claim 3, said sheath extending around said tampon body and overlapping the tampon body with a pair of flaps, said flaps gripping each other slightly so as to hold said tampon body at a diameter that is slightly less than the inner diameter of said outer tube.
Claim 9
Dependent Claim
14 words
A tampon assembly as set forth in claim 3, said sheath being of polyethylene.
Claim 10
Dependent Claim
35 words
A tampon assembly as set forth in claim 3, said sheath also extending for the length of said inner tube and being tucked into the end of said inner tube remote from said tampon body.
Claim 11
Dependent Claim
31 words
A tampon assembly as set forth in claim 3, said tampon body having a rounded end protruding from the end of said outer tube and said sheath covering said rounded end.
Claim 12
Dependent Claim
29 words
A tampon assembly as set forth in claim 9, said sheath having a flap extending from said rounded end of said tampon body and extending into said outer tube.
