<p><P>PROBLEM TO BE SOLVED: To provide a container including an inner tray lifting mechanism capable of smoothly lifting an inner tray with simple structure with no risk of liquid leakage between the outer periphery of the inner tray and the inner periphery of a container body in the container provided with an operating handle C with a threaded shaft 41 operably from the outside to the container body A having a circular inner peripheral surface, and configured to push up liquid stored above the inner plate E by rotating the threaded shaft 41 by the relative turning of the operating handle C to the container body A to lift the inner tray E with its inner peripheral edge threadedly engaged with the threaded shaft 41. <P>SOLUTION: An elastic turning preventive protrusion 55 with its outer edge slidably making press-contact with the inner peripheral part of the container body A in a state of being tilted in a predetermined circumferential direction, is protrusively provided at the lower part of a portion sliding along the inner peripheral part of the container body A, of the outer periphery of the inner tray E. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
