<P>PROBLEM TO BE SOLVED: To provide a lid body for easily opening/closing an openable/closable lid part, preventing any careless detachment from a vessel, and reliably maintaining a capped condition on the vessel. <P>SOLUTION: A top plate part 5 comprises a fixed lid part 8 to close a part of an opening part 3 of a vessel 2, and an openable/closable lid part 10 continuous to the fixed lid part 8 via a hinge part 9. An annular skirt part 6 is integrated with a peripheral edge of the top plate part 5. A screw part 7 to be screwed to a threaded part 4 of the vessel is provided on the skirt part 6. A fracture part 12 is provided between the screw part 7 of the skirt part 6 and a circumferential edge of the openable/closable lid part 10. When the fracture part 12 is broken to open/close the openable/closable lid part 10, a connected condition to the vessel is maintained via the fixed lid part 8 and the skirt part 6. <P>COPYRIGHT: (C)2004,JPO |
