Abstract

Abstract A tampon inserter is disclosed of the type comprising an outer cylindrical insertion tube containing a compressed tampon in its proximal end and an inner plunger or piston axially movable within the outer tube for ejecting the tampon out of the proximal end of the insertion tube into the vagina. The outer insertion tube which is rotatable about the plunger is provided with (a) an outwardly extending annular ring to control the depth of insertion of the inserter and (b) an inwardly directed key or finger which depending upon the degree of rotation of the insertion tube about the plunger will extend into one of a plurality of elongated slots of various lengths positioned in the walls of the inner plunger which (slots) control the length of travel of the plunger and thereby provide a means for varying the depth of insertion of the tampon.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 148 words
A tampon inserter having means for varying the depth of insertion of said tampon, said inserter comprising a cylindrical insertion tube having a proximal end and a distal end, said tube being adapted to receive a tampon in said proximal end, an outwardly extending annular ring fixedly attached to the outer surface of said insertion tube, an inwardly extending flexible finger fixedly attached to said insertion tube adjacent the distal end, an elongated plunger which is axially movable within said insertion tube for expelling the tampon, a plurality of elongated sots of varying length in the walls of said plunger, said slots being aligned lengthwise so as to be parallel to the axis of said plunger, and said insertion tube being circumferentially rotatable about said plunger whereby said finger may extend into any of said slots and thereby variably control the extent of axial travel of said plunger.
Claim 2
Dependent Claim 148 words
A tampon inserter having means for varying the depth of insertion of said tampon, said inserter comprising a cylindrical insertion tube having a proximal end and a distal end, said tube being adapted to receive a tampon in said proximal end, an outwardly extending annular ring fixedly attached to the outer surface of said insertion tube, an inwardly extending flexible finger fixedly attached to said insertion tube adjacent the distal end, an elongated plunger which is axially movable within said insertion tube for expelling the tampon, a plurality of elongated sots of varying length in the walls of said plunger, said slots being aligned lengthwise so as to be parallel to the axis of said plunger, and said insertion tube being circumferentially rotatable about said plunger whereby said finger may extend into any of said slots and thereby variably control the extent of axial travel of said plunger.
Claim 3
Dependent Claim 24 words
A tampon inserter as defined in claim 1 in combination with a tampon which is disposed within the proximal end of said insertion tube.
