<P>PROBLEM TO BE SOLVED: To provide a stopper of a drink container which enables a lid member to be opened/closed easily, keeps the lid member closed firmly, and is superior in design property. <P>SOLUTION: The stopper has a hinge 5, and a lock mechanism 7 is formed in opposite to the hinge 5 of a stopper 3. The lock mechanism 7 comprises an engaging piece 8 formed on the lid member 6, a seesaw lock button 10, which is attached to a mouth stopper member 4 to be turnable inward and outward relative to the mouth stopper member 4 via a pivot member 9 formed on the mouth stopper member 4, and a slidable stopper 11 which is formed slidably on the outer peripheral wall of the mouth stopper member 4. The lock button 10 has an engaging part with which the engaging piece 8 engages and disengages, and a spring 13 which applies energy to the engaging part to keep pushing it in a direction of engagement with the engaging piece 8. The slidable stopper 11 has a stopper piece 11a which regulates the move of the lock button 10 in a lock release direction when inserted between the lower part of the lock button 10 and the outer peripheral wall of the mouth stopper member 4, and a projection 11c which holds the slidable stopper 11 at an insertion position and a noninsertion position of the stopper piece 11a. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
