Title: Closure member of packaging container
Inventor: TAKAYAMA TOSHIAKI
IPC: B65D41/12
Filed: 2003-09-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a closure member, of which the engagement force and airtightness are improved without complicating a structure of the closure member to reduce leaks of a content.  <P>SOLUTION: The closure member 40 of a packaging container is engaged with a mouthpiece of the container, and a bulged part 42 of the closure member 40 is pressed to separate a skirt 41 of the closure member 40 in deformation from the mouthpiece. The closure member 40 has nails 43, and at least part of the shoulder to the lower end of the edge of each nail in the circumference is formed to slope in a given direction. With the sloped edges, a distance between the lower end of one edge and the vicinity to the shoulder of another edge becomes relatively longer than in a case where the nails 43 are provided in the same number but are not sloped. As a result, when an inner pressure is applied to the closure member 40 to pressed it in a direction of removal, a force to widen the nails 43, which is a result of the bulging of a cylindrical part 11b of the mouth piece 11, acts differently on the nails 43 in comparison with the case of the nails with no slope. Thus the closure member 40 retains a higher engagement force and airtightness without losing openability.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
