<p><P>PROBLEM TO BE SOLVED: To provide a laboratory dish which has simple structure and with which a dish and a lid are simultaneously and readily grasped by one hand and even only the lid is readily removed. <P>SOLUTION: The laboratory dish comprises a circular flat-bottomed dish 10 and a circular lid 20 to cover the dish 10. The dish 10 has an outer peripheral wall 11 and an inner peripheral wall 12 and the lid 20 has an outer peripheral wall 21. The inner peripheral wall 12 of the dish 10 is positioned inside the outer peripheral wall 21 of the lid 20 when the dish 10 is covered with the lid 20 and has a length to abut on the inside of the lid 20. The tip ends of both the outer peripheral walls 11 and 21 face and the outer peripheral faces of both the outer peripheral walls 11 and 12 are approximately flush in the state of the dish 10 covered with the lid 20. Consequently, the dish 10 and the lid 20 are simultaneously and readily grasped even by one hand and the bad condition of dropping especially the dish 10 in movement hardly occurs. When only the lid 20 is removed, only the lid 20 is readily removed with slight fear of grasping the dish 10 simultaneously by one hand. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
