Abstract

Abstract A digital tampon of unitary construction made of absorbent material capable of being compressed to self-sustaining form. A portion of the material is compressed to a rod-like shape to provide a rigid central support for the remaining relatively uncompressed portion which originates at the top of the rigid central support and is draped downwardly to surround and extend past the lower terminus of the support to form a finger receiving pocket at the tampon base. During insertion the rigid central rod provides positive support to the softer outer portion, while the portion of the tampon surrounding the finger protects the finger from contact with menstrual fluid. After insertion the finger can easily spread the draped over portion to better deploy and position the tampon within the body.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 90 words
A tampon of unitary construction comprised of a compressible absorbent material a lower portion of said material being compressed to provide a rigid insertion means for finger contact and support of soft outer shell during insertion, the remaining upper portion of said material being relatively uncompressed and being draped downwardly from the top of said insertion means to surround said insertion means and extend past the lower terminus of said insertion means to provide a downwardly-facing finger-receiving pocket, and a withdrawal string secured to and extending from said insertion means.
Claim 2
Dependent Claim 90 words
A tampon of unitary construction comprised of a compressible absorbent material a lower portion of said material being compressed to provide a rigid insertion means for finger contact and support of soft outer shell during insertion, the remaining upper portion of said material being relatively uncompressed and being draped downwardly from the top of said insertion means to surround said insertion means and extend past the lower terminus of said insertion means to provide a downwardly-facing finger-receiving pocket, and a withdrawal string secured to and extending from said insertion means.
Claim 3
Dependent Claim 135 words
A digital tampon comprising a generally elongate absorbent body of unitary construction, said body being comprised of a compressible absorbent material; a lower portion of said absorbent body having been radially compressed to provide a rigid centrally disposed insertion means for finger contact and support of soft outer shell during insertion, having a top end and a bottom end; the remaining upper portion of said absorbent body being relatively uncompressed with said upper portion overhanging the top end of said insertion means to substantially surround said insertion means and extend below the bottom end of said insertion means to provide a small downward facing finger-receiving pocket based at the bottom end of said insertion means; and a withdrawal cord, one end of which is secured to at least the bottom end of said insertion means.
Claim 4
Dependent Claim 135 words
A digital tampon comprising a generally elongate absorbent body of unitary construction, said body being comprised of a compressible absorbent material; a lower portion of said absorbent body having been radially compressed to provide a rigid centrally disposed insertion means for finger contact and support of soft outer shell during insertion, having a top end and a bottom end; the remaining upper portion of said absorbent body being relatively uncompressed with said upper portion overhanging the top end of said insertion means to substantially surround said insertion means and extend below the bottom end of said insertion means to provide a small downward facing finger-receiving pocket based at the bottom end of said insertion means; and a withdrawal cord, one end of which is secured to at least the bottom end of said insertion means.
Claim 5
Dependent Claim 173 words
In a tampon adapted for digital insertion and which comprises a central rigidified core member surrounded by an outer absorptive and fluid-permeable member and is further provided with a withdrawal cord and a finger-receiving pocket at the bottom end to facilitate insertion; the improvement wherein the tampon comprises a unitary body of compressible absorbent material; in which the central core member is a rigid insertion means for finger contact and support of soft outer shell during insertion comprised of a lower portion of said unitary body compressed to self-sustaining condition; in which the outer member is comprised of the remaining upper portion of said unitary body in substantially uncompressed condition and integral with said insertion means; in which said outer members extends out from the top end of said insertion means, hangs downward around on all sides of said insertion means, and terminates beyond the bottom end of said insertion means to form a finger-receiving pocket based at said bottom end; and in which said withdrawal cord is secured to said insertion means.
Claim 6
Dependent Claim 173 words
In a tampon adapted for digital insertion and which comprises a central rigidified core member surrounded by an outer absorptive and fluid-permeable member and is further provided with a withdrawal cord and a finger-receiving pocket at the bottom end to facilitate insertion; the improvement wherein the tampon comprises a unitary body of compressible absorbent material; in which the central core member is a rigid insertion means for finger contact and support of soft outer shell during insertion comprised of a lower portion of said unitary body compressed to self-sustaining condition; in which the outer member is comprised of the remaining upper portion of said unitary body in substantially uncompressed condition and integral with said insertion means; in which said outer members extends out from the top end of said insertion means, hangs downward around on all sides of said insertion means, and terminates beyond the bottom end of said insertion means to form a finger-receiving pocket based at said bottom end; and in which said withdrawal cord is secured to said insertion means.
Claim 7
Dependent Claim 26 words
The tampon of claim 3 wherein said unitary body comprises an elongate strip transversely folded substantially in half with said lower portion originating at the fold
Claim 8
Dependent Claim 28 words
The tampon of claim 4 wherein said upper portion comprises the free ends of said folded strip folded downwardly over said central core and forming said finger-receiving pocket.
Claim 9
Dependent Claim 17 words
The tampon of claim 3 wherein said unitary body is in the form of a cylindrical tube.
Claim 10
Dependent Claim 19 words
The tampon of claim 6 wherein the upper portion of said tube has a multiplicity of spaced longitudinal slits.
Claim 11
Dependent Claim 39 words
The tampon of claim 3 wherein said unitary body comprises an elongate strip transversely folded in half with the free ends secured together by the withdrawal cord and with said lower portion originating at said secured together free ends.
Claim 12
Dependent Claim 43 words
The tampon of claim 8 wherein said upper portion extends to the closed end of said folded strip, and the sides of said upper portion are hinged outweardly and draped downwardly over said central core and forming the walls of said finger-receiving pocket.
Claim 13
Dependent Claim 39 words
The tampon of claim 3 wherein said unitary body comprises a multiplicity of strips crossing each other at their approximate mid-points, said crossed strips being folded transversely at said mid-point with said lower portion originating at said mid-point fold.
Claim 14
Dependent Claim 28 words
The tampon of claim 10 wherein said upper portion comprises the free ends of said crossed strips draped downwardly over said central core and forming said finger-receiving pocket.
Claim 15
