Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 149 words
A tampon comprising: a hollow accommodation barrel; an absorbent material disposed within said accommodation barrel, said accommodation barrel including a flexible cylindrical sheet portion and a rigid cylindrical portion connected to said flexible cylindrical sheet portion such that said absorbent material is primarily contained within said flexible cylindrical sheet portion; and a take-out device having a length longer than said accommodation barrel and connected to a front end portion of said flexible cylindrical sheet portion for removing said flexible cylindrical sheet portion from said absorbent material whereby after the accommodation barrel is inserted into the vagnia the front end of the flexible cylindrical sheet portion housing the absorbent material is pulled up within said rigid cylindrical portion so that the flexible sheet portion is peeled off the absorbent material and such that setting the absorbent material in place can be finished without moving the absorbent material in the vagina.
Claim 2
Dependent Claim 149 words
A tampon comprising: a hollow accommodation barrel; an absorbent material disposed within said accommodation barrel, said accommodation barrel including a flexible cylindrical sheet portion and a rigid cylindrical portion connected to said flexible cylindrical sheet portion such that said absorbent material is primarily contained within said flexible cylindrical sheet portion; and a take-out device having a length longer than said accommodation barrel and connected to a front end portion of said flexible cylindrical sheet portion for removing said flexible cylindrical sheet portion from said absorbent material whereby after the accommodation barrel is inserted into the vagnia the front end of the flexible cylindrical sheet portion housing the absorbent material is pulled up within said rigid cylindrical portion so that the flexible sheet portion is peeled off the absorbent material and such that setting the absorbent material in place can be finished without moving the absorbent material in the vagina.
Claim 3
Dependent Claim 99 words
