An applicator for a tampon, comprising:</claim-text> an outer cylinder including forward and rearward ends, a first portion for fitting the tampon therein formed on a side of the forward end, and a second portion formed on a side of the rearward end aving a smaller diameter than that of said first portion, a push-out member movably inserted into said second portion of said outer cylinder, and a plurality of valves provided with the forward end of said outer cylinder, each valve being converged to have a curved face portion to be diametrically gradually reduced and define a leading end, wherein a ratio of a radius of an outer face at an inflection point of a boundary between a maximum diameter portion of said first diameter portion and said curved face portion to an axial length of the outer face from the inflection point to the leading end of said curved face portion is at most 0.8; and wherein a ratio of a length of said valves to a width of root ends of said valves is 1.0 to 2.0. view more

An applicator for a tampon as set forth in claim 1,</claim-text> wherein the root ends of said valves are located substantially at the inflection point.

An applicator for a tampon, comprising:</claim-text> an outer cylinder including forward and rearward ends, a first portion for fitting a tampon therein formed on a side of the forward end, and a second portion formed on a side of the rearward end aving a reduced diameter relative to said first portion, a push-out member movably inserted into said second portion of said outer cylinder, and a plurality of valves provided with the forward end of said outer cylinder, each having a root end, a curved face portion to be diametrically gradually reduced, a leading end, a first inflection point at the root end of said valve and a second inflection point adjacent to the leading end of said valves, a curvature radius for said first inflection point being larger than a curvature radius for said second inflection point, wherein a ratio of a radius of an outer radius at said first inflection point to an axial length of said curved face from said first inflection point to the leading end of said curved face portion is at most 0.8; and wherein a ratio of a length of said valves to a width of said root ends of said valves is 1.0 to 2.0. view more

An applicator for a tampon comprising:</claim-text> an outer cylinder made of a thermoplastic resin and including forward and rearward ends, a first portion for accommodating the tampon therein formed on a side of the forward end, and a second on formed on a side of the rearward end and having a reduced diameter relative to said first portion; a push-out member movably inserted into said second portion of said outer cylinder; a plurality of valves provided with the forward end of said outer cylinder, each valve being converged to have a curved face portion to be diametrically gradually reduced and define a leading end; wherein a ratio of an outer radius at an inflection point of a boundary between a maximum diameter portion of said first portion and said curved face portion to an axial length of said curved face portion from the inflection point to the leading end of said curved face portion is at most 0.8; and wherein a ratio of a length of said valves to a width of root ends of said valves is 1.0 to 2.0. view more
