Abstract
Abstract A compact tube applicator is provided in which a nesting telescoping inner tube has slits on its leading edge to receive the tampon pledget and a ring positioned around the trailing end, the trailing end being narrower in diameter than the leading end when the inner tube is pulled backward, the tampon is expelled through the leading ends of the two tubes by the inwardly compressive forces provided by the ring.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
228 words
A compact tampon applicator comprising an outer tampon tube with an insertion end and a gripping end and an inner tube and an annular member having: (a) a tampon pledget-surrounding leading end of said inner tube, positioned circumferentially inward from said insertion end of said outer tube while the pledget is stored therein, said leading end having a plurality of slits extending essentially parallelly downward along the tube length and a plurality of flanges extending radially outward from said leading end (b) a trailing end of said inner tube positioned radially inward from the gripping end of said outer tube when the tampon is stored in said leading end, said trailing end having substantially reduced diameter when compared to said leading end; and said annular member circumferentially surrounding said trailing end, said annular member having an inner diameter greater than the outer diameter of said trailing end but smaller than the diameter of said leading end, said annular member having an outer diameter greater than the inner diameter of said gripping end of said outer tube wherein when said inner tube is withdrawn through said griping end said annular member compresses said leading end expelling said tampon from said leading end and narrowing said leading end so that the leading end may be pressed against said tampon to expel it from said insertion end of said tampon tube.
Claim 2
Dependent Claim
228 words
A compact tampon applicator comprising an outer tampon tube with an insertion end and a gripping end and an inner tube and an annular member having: (a) a tampon pledget-surrounding leading end of said inner tube, positioned circumferentially inward from said insertion end of said outer tube while the pledget is stored therein, said leading end having a plurality of slits extending essentially parallelly downward along the tube length and a plurality of flanges extending radially outward from said leading end (b) a trailing end of said inner tube positioned radially inward from the gripping end of said outer tube when the tampon is stored in said leading end, said trailing end having substantially reduced diameter when compared to said leading end; and said annular member circumferentially surrounding said trailing end, said annular member having an inner diameter greater than the outer diameter of said trailing end but smaller than the diameter of said leading end, said annular member having an outer diameter greater than the inner diameter of said gripping end of said outer tube wherein when said inner tube is withdrawn through said griping end said annular member compresses said leading end expelling said tampon from said leading end and narrowing said leading end so that the leading end may be pressed against said tampon to expel it from said insertion end of said tampon tube.
Claim 3
Dependent Claim
21 words
The tampon applicator of claim 1 wherein said annular member is engaged with said flanges upon withdrawal of said inner tube.
Claim 4
Dependent Claim
32 words
The tampon applicator of claim 1 wherein said annular member rests against a shoulder formed in the outer tube in the area where it narrows to the diameter of said gripping end.
Claim 5
Dependent Claim
16 words
The tampon applicator of claim 1 wherein said inner and outer tubes are formed of plastic.
Claim 6
Dependent Claim
88 words
A compact tampon applicator comprising an inner tube, a sliding member engaging said inner tube and an outer tube wherein said inner tube comprises a tubular member slit at the insertion end into a multiplicity of fingers having a flange on the ends of at least one of said fingers and wherein said outer tube is of larger diameter at the insertion end than at the griping end and wherein said inner tube passes through said gripping end but said sliding member cannot pass through said gripping end.
Claim 7
Dependent Claim
88 words
A compact tampon applicator comprising an inner tube, a sliding member engaging said inner tube and an outer tube wherein said inner tube comprises a tubular member slit at the insertion end into a multiplicity of fingers having a flange on the ends of at least one of said fingers and wherein said outer tube is of larger diameter at the insertion end than at the griping end and wherein said inner tube passes through said gripping end but said sliding member cannot pass through said gripping end.
Claim 8
Dependent Claim
19 words
The tampon applicator of claim 5 wherein said pledget is placed between the split ends of said inner tube.
Claim 9
Dependent Claim
22 words
The tampon applicator of claim 5 wherein said sliding member has an inner diameter such that it cannot slide past said flanges.
Claim 10
Dependent Claim
25 words
The tampon applicator of claim 5 wherein said outer tube is provided with petals that are opened when expelling a pledget from said outer tube.
Claim 11
Dependent Claim
18 words
The tampon of claim 5 wherein said flanges are formed by bending the ends of said fingers outward.
Claim 12
Dependent Claim
28 words
The tampon applicator of claim 5 wherein said a shoulder is formed in the area of said outer tube where the tube is narrowed to the gripping diameter.
Claim 13
Dependent Claim
31 words
The tampon applicator of claim 10 wherein said shoulder stops said sliding member and forces it into contact with said engaging contact with said flange when said inner tube is withdrawn.
