Biochemical container

Abstract

A biochemical container is provided, which can open a cover member shutting a container member and can release a tightly sealed condition, without a need for displacing the outer edge section of the cover member. In the present invention, an opening in an end of a container member 110 is openably and closably shut by a cover member 120 . When an assisting-opening member 140 is pressed from the outside in such shut condition, the stress is changed to the opening direction by the changing-direction mechanism 150 to exert over the cover member 120 . Consequently, the tightly sealed condition of the cover member 120 that shuts the container member 110 can be released.
