A container with a lid comprises a container portion ( 10 ) having an opening portion ( 11 ) for the loading or unloading of a sample or the like, a lid portion ( 20 ) that can be detachably fitted in said opening portion ( 11 ) so as to close the same, and a lever mechanism portion ( 30 ) for opening said lid portion ( 20 ) in a closed state using leverage. The lever mechanism portion ( 30 ) is composed of a lever portion ( 33 ) having a force-applied point (P) portion that is pressed by a finger and an action point (Q) portion that is pressed against an external periphery portion of said lid portion ( 20 ) when pressed with the finger so as to open the same, and a support portion ( 31, 32 ) for supporting said lever portion ( 33 ) via a thin-walled portion ( 35 ) that constitutes a fulcrum (O)portion, in a freely swinging manner. The lever mechanism portion ( 30 ) allows the lid portion ( 20 ) to be easily opened with one hand without putting much burden on the fingers even if it is very tightly closed. In addition, a lock mechanism portion ( 70 ) is provided that locks the lid portion ( 20 ) when it is closed. Optionally, in response to a closing operation of the lid portion ( 20 ), the lid portion ( 20 ) is automatically locked by the lock mechanism portion ( 70 ), and in response to an opening operation of the lid portion ( 20 ) by the lever mechanism portion ( 60 ), the locking of the lid portion ( 20 ) by the lock mechanism portion ( 70 ) is automatically released.
