Abstract
Abstract A segmented, domed-tipped, tubular applicator for the insertion of catamenial tampons intravaginally is provided with sinusoidal curvilinear ribs positioned centrally and extending axially and radially on the inner surface of each of the dome segments to spread the segments apart and permit the tampon to be expelled from the applicator.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
A domed tipped applicator for catamenial tampons comprising: a. a first tubular member containing a tampon; b. a second tubular member telescoped for slideable engagement within said first tubular member and adapted to expel said tampon from the forward end of said first tubular member; c. a plurality of substantially triangularly shaped segments integral at their respective bases with the forward end of said first tubular member and having their respective apices converging forwardly and being radially spaced from one another to define an opening having a diameter smaller than the internal diameter of said first tubular member; and d. guIde means disposed on the inner surface of each of said triangularly shaped segments for pivoting said segments radially outwardly to a position where the diameter of said opening defined by said apices is at least equal to the internal diameter of said first tubular member prior to the forward end of said tampon reaching said apices upon expulsion of said tampon from said applicator.
Claim 2
Dependent Claim
165 words
A domed tipped applicator for catamenial tampons comprising: a. a first tubular member containing a tampon; b. a second tubular member telescoped for slideable engagement within said first tubular member and adapted to expel said tampon from the forward end of said first tubular member; c. a plurality of substantially triangularly shaped segments integral at their respective bases with the forward end of said first tubular member and having their respective apices converging forwardly and being radially spaced from one another to define an opening having a diameter smaller than the internal diameter of said first tubular member; and d. guIde means disposed on the inner surface of each of said triangularly shaped segments for pivoting said segments radially outwardly to a position where the diameter of said opening defined by said apices is at least equal to the internal diameter of said first tubular member prior to the forward end of said tampon reaching said apices upon expulsion of said tampon from said applicator.
Claim 3
Dependent Claim
29 words
The applicator of claim 1 wherein said guide means comprises a rib centrally disposed and extending axially and radially on the inner surface of each of said triangular segments.
Claim 4
Dependent Claim
29 words
The applicator of claim 2 wherein said rib presents an inner edge that defines a sinusoidal curvilinear surface for bearing against said tampon upon expulsion thereof from said applicator.
Claim 5
Dependent Claim
31 words
The applicator of claim 3 wherein the surface area of the inner edge of said rib is less than the surface area of the inner surface of its triangularly shaped segment.
