摘要： PROBLEM TO BE SOLVED: To provide a plastic cap configured so that an engagement projection of a cap body can slide over an engagement part of a container mouth part smoothly, a decrease or the like in fitting force of an upper lid which results from capping is effectively prevented, and categorized disposability is excellent. SOLUTION: A thin-wall breakable line 13 is formed in a cap body skirt part below the engagement projection 11 of skirt parts 3a and 3b so as to extend in a peripheral direction and so as to be torn. The plastic cap can be easily detached from the container mouth part 50 after exhaustion of the content, by tearing off the breakable line 13. On the internal face of the skirt parts are: a plurality of upper ribs 12, each of which is formed below the engagement projection and has a tapering internal face whose inside diameter increases toward a lower side; and a plurality of lower ribs 14, each of which is formed below the breakable line and has a tapered internal face whose inside diameter increases toward a lower side. The plurality of upper ribs and the plurality of lower ribs are formed so as to be displaced from each other in the peripheral direction. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a hinge cap which facilitates opening/closing of the upper lid regardless of the form of fitting of a cap body on a container mouth, prevents suction of cooling water into a spout cylinder resulting from filling hot contents liquid, and facilitates smooth discharge or drying out of the cooling water in the case of suction of the cooling water out of the spout cylinder. SOLUTION: The cap body includes an outer wall and the spout cylinder, the outer wall having a locking projection on its exterior and an arcuate surface on its interior. The upper lid includes a side wall, a seal cylinder, and an inner ring. A locked projecting line is formed on the inner peripheral surface of the side wall, and an annular tongue piece having a sloped surface is formed at the lower end of the seal cylinder. Two notches made by cutting out the locking projecting line are formed to be symmetrical in position with respect to a line L1 connecting the center of a hinge to an upper lid flange opposite to the center. When the upper lid is closed, the arcuate surface comes in pressure contact with the sloped surface to cause the seal cylinder to shift inward to ease the engagement between the locking projecting stripe and the locked projecting line and release the notches the engagement. This facilitates opening/closing of the upper lid. COPYRIGHT: (C)2009,JPO&INPIT
