<P>PROBLEM TO BE SOLVED: To easily attach/detach a lid body to/from a container body while providing sufficient clicking feeling when the lid is fitted to the container body. <P>SOLUTION: As shown in the Fig.(a), a body side screw thread 12 is formed on an outer peripheral face of a mouth part 11 of the container body 10 to which the lid body can be fitted by screwing. A notch 13 separating a tip portion (stopper 14) on the upper end side from a remaining part is formed in the body side screw thread 12, and a rib fitted to the notch 13 at the end of screwing operation for fitting the lid body to the container body 10 is provided in the lid body. Since the stopper 14 is formed to have a narrower width compared to a structure shown in Fig.(b) in which only the notch 13 is formed, a contact area between the stopper 14 and the rib can be reduced, so as to lower torque. A trajectory itself of the rib when the rib rides over the stopper 14 is not changed, so as to prevent deterioration of clicking feeling. <P>COPYRIGHT: (C)2012,JPO&INPIT |
