<P>PROBLEM TO BE SOLVED: To provide a synthetic resin cap capable of positively carrying out a sealing operation by integrally assembling a sealing mechanism having a simple structure into a cap. <P>SOLUTION: This synthetic resin cap is made such that the upper surface of a peripheral wall fitted to the outer surface of the neck part of a container is closed by a lid member suspended down at a container cylinder from an outer periphery of a top plate, an upper end of rear part of the peripheral wall and a lower end of rear part of a short cylinder are connected through a hinge and a finger hook protrusion for use in opening the lid is protruded from the front part of the short cylinder. A first arcuate plate 19 having both right and left portions removably connected to the outer surface of an upper part of a front portion of the peripheral wall 2 is laterally arranged and a second arcuate plate 21 having both right and left portions removably connected outside both right and left ends of the finger hook protrusion under a state covering the front surface of the finger hook protrusion 17 is laterally arranged, and these both arcuate plates are overlapped up and down and inseparably connected. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
