<p><P>PROBLEM TO BE SOLVED: To provide a resin container which has an upper member that can be easily separated from an incision, and is applicable to a variety of use, such as an ampul, and to provide a manufacturing method of the container. <P>SOLUTION: The resin container comprises a container body 11 which has a mouth 14 formed in continuity with the shoulder 13 of a trunk 12 containing a liquid at the upside of the shoulder 13, a bulged part 21 which is formed to be integral to the mouth 14 at its upside, where the inside of the bulged part 21 communicates with the mouth 14, and a tab 31 which is formed at the upside of the bulged part 21 and is severed and removed, together with the bulged part 21, upon using the container. The incision 41 of an almost V shape is formed circumferentially along the outer circumferential surface of the boundary between the mouth 14 and the bulged part 21. On the inner circumferential surface of the incision 41, a conical inner tapered surface 43 is formed to be continuous from upper to lower parts across the front end of the incision 41 and widen in diameter upwardly. The inner tapered surface 43 has a widening angle Y smaller than the widening angle X of a conical outer tapered surface 42 which is formed on the upside of the front end of the incision 41 and widens upwardly in diameter. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
