Abstract
Abstract An improved vaginal cup having axially aligned inwardly extending ribs disposed on an inner surface adjacent the closed end thereof. A manually engageable loop is provided on the outer surface of said closed end, application of an axially aligned force on said loop for the purpose of withdrawing the cup serving to elongate the same along its axis, and simultaneously decrease the effective diameter to facilitate such withdrawal.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
135 words
In a vaginal cup, including a cup-shaped container having a principal longitudinal axis, and having an outer surface and an upwardly facing mouth, the improvement comprising: said cupshaped container including a generally frustoconical portion, and a quasi-spherical portion communicating therewith at the smaller end of said frustoconical portion, said frustoconical portion and said quasi-spherical portion defining a continuous inner surface; loop forming means extending from an outer surface of said quasispherical portion, for the purpose of manually removing said cup from operative position; and a plurality of generally planar ribs extending inwardly from said inner surface in the area of said quasi-spherical portion, said ribs tending to resiliently resist bending of said container about an axis substantially perpendicular to said principal axis, while permitting limited bending of said container about an axis substantially parallel thereto.
Claim 2
Dependent Claim
135 words
In a vaginal cup, including a cup-shaped container having a principal longitudinal axis, and having an outer surface and an upwardly facing mouth, the improvement comprising: said cupshaped container including a generally frustoconical portion, and a quasi-spherical portion communicating therewith at the smaller end of said frustoconical portion, said frustoconical portion and said quasi-spherical portion defining a continuous inner surface; loop forming means extending from an outer surface of said quasispherical portion, for the purpose of manually removing said cup from operative position; and a plurality of generally planar ribs extending inwardly from said inner surface in the area of said quasi-spherical portion, said ribs tending to resiliently resist bending of said container about an axis substantially perpendicular to said principal axis, while permitting limited bending of said container about an axis substantially parallel thereto.
Claim 3
Dependent Claim
64 words
Structure in accordance with claim 1, said ribs being free of interconnection with the area of said quasi-spherical portion at which said loop forming means is attached, whereby an axially aligned force may be readily transmitted to said container to result in resiliently deforming the same in such manner that the effective diameter of the closed end thereof is materially reduced to facilitate removal.
Claim 4
Dependent Claim
29 words
Structure in accordance with claim 2, said container having an external annular rib at least partially overlying each of said planar ribs to effect, in concert, a sealing function.
