Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
220 words
A tampon, comprising: an elongated outer cylinder having an outer end and having an inner end adapted for insertion into a vagina, a mass of absorbent material disposed inside said outer cylinder close to the inner end thereof and adapted to be moved through said inner end of said outer cylinder, said outer cylinder having one or more through holes formed in the side wall thereof at a location spaced from the inner end of said outer cylinder and in the region of the outer end of said mass of absorbent material; a push-out member mounted on said outer cylinder for sliding movement in a direction lengthwise thereof, said push-out member having one or more longitudinally extending push-out pieces corresponding in number to the number of said holes, said push-out pieces being disposed outside of said outer cylinder, said push-out pieces having a size such that they can be extended through said holes into the interior of said outer cylinder for engaging said mass of absorbent material in response to movement of said push-out member relative to said outer cylinder and then longitudinal movement of said push-out member in a direction toward the inner end of said outer cylinder causes said push-out pieces to move said mass of absorbent material out of said outer cylinder through the inner end thereof.
Claim 2
Dependent Claim
220 words
A tampon, comprising: an elongated outer cylinder having an outer end and having an inner end adapted for insertion into a vagina, a mass of absorbent material disposed inside said outer cylinder close to the inner end thereof and adapted to be moved through said inner end of said outer cylinder, said outer cylinder having one or more through holes formed in the side wall thereof at a location spaced from the inner end of said outer cylinder and in the region of the outer end of said mass of absorbent material; a push-out member mounted on said outer cylinder for sliding movement in a direction lengthwise thereof, said push-out member having one or more longitudinally extending push-out pieces corresponding in number to the number of said holes, said push-out pieces being disposed outside of said outer cylinder, said push-out pieces having a size such that they can be extended through said holes into the interior of said outer cylinder for engaging said mass of absorbent material in response to movement of said push-out member relative to said outer cylinder and then longitudinal movement of said push-out member in a direction toward the inner end of said outer cylinder causes said push-out pieces to move said mass of absorbent material out of said outer cylinder through the inner end thereof.
Claim 3
Dependent Claim
72 words
A tampon as claimed in claim 1, in which said through hole or holes is or are spaced from the inner end of said outer cylinder a distance larger than the length of said mass of absorbent material, said push-out member being located adjacent the outer end of said outer cylinder with said push-out pieces extending longitudinally therefrom and slidably engaging the outer surface of the side wall of said outer cylinder.
Claim 4
Dependent Claim
62 words
A tampon as claimed in claim 2 wherein the inner end of said outer cylinder has a semi-spherical face having slits therein defining flexible flaps so that said mass of absorbent material can be moved therethrough, said push-out pieces extending substantially to said face and the end portions of said push-out pieces being inwardly curved to engage portions of said semi-spherical face.
Claim 5
Dependent Claim
46 words
A tampon as claimed in claim 1, claim 2 or claim 3, wherein the portion of said outer cylinder between said holes and the outer end thereof is of smaller diameter than the portion of said outer cylinder between said holes and the inner end thereof.
Claim 6
Dependent Claim
39 words
A tampon as claimed in claim 1, claim 2 or claim 3 in which said push-out member comprises a second cylinder coaxial with said outer cylinder, said push-out pieces extending longitudinally from one axial end of said second cylinder.
Claim 7
Dependent Claim
38 words
A tampon as claimed in claim 1, claim 2 or claim 3 in which said outer cylinder has laterally outwardly extending guide wall means for engaging the longitudinal edges of said push-out pieces for guiding longitudinal movement thereof.
Claim 8
Dependent Claim
138 words
A tampon as claimed in claim 1, claim 2 or claim 3 in which said outer cylinder has two holes located on diametrically opposite portions thereof and has a laterally outwardly extending annular flange on the outer end thereof, said flange having two slots therethrough in longitudinal alignment with said holes, said push-out member comprises a second cylinder coaxial with and of substantially the same diameter as said outer cylinder and being disposed outwardly from said outer end of said outer cylinder, said push-out pieces comprising two elongated, diametrically opposed legs extending longitudinally from said second cylinder, through said slots and lengthwise of said outer cylinder substantially to the inner end thereof, said legs being curved to conform to the circumferential curvature of the opposing portions of the external surface of said outer cylinder that they slidably engage.
