<P>PROBLEM TO BE SOLVED: To easily attach a wiper to an opening neck part with a simple composition, and to prevent the wiper from coming off from the opening neck part. <P>SOLUTION: In the composition, thick parts 14 axially extended and internally projected are circumferentially arranged in parallel on an inner circumferential surface of a wiper 6 so that uneven parts are lined up. When attaching the wiper 6 to the opening neck part 4, a recess part 20 is throttled, facilitating the attachment. In addition, a stepped part 13 of the wiper 6 prevents the stepped part 12 of the container body 1 from coming off. The thick parts 14 circumferentially arranged apart on the inner circumferential surface of the wiper 6 and projected toward the inner side suppresses the wiper 6 from being inwardly throttled. The thick parts 14 are positioned on the inner circumferential surface at the inner side in the diameter direction of the stepped part 13 of the wiper 6 so that the engagement release between the stepped parts 12, 13 is suppressed, thus, preventing the wiper 6 from coming off. <P>COPYRIGHT: (C)2013,JPO&INPIT |
