ABSTRACT:
A tissue cassette for holding biological tissue specimens. The tissue cassette includes an open topped, perforated base member adapted to receive a tissue specimen, a perforated lid member adapted to cover the base member and a snap action hinge joining the base member to the perforated lid. The snap action member can be J-shaped, sinusoidal shaped or L-shaped. Further, the cassette can include a living hinge for joining the base member to the open topped base member. The living hinge includes a first end attached to the lid member, a second end attached to the base member, a flat first surface and a curved second surface, whereby the hinge thickness varies across the length of the hinge and the thinnest portion of the hinge is positioned between the hinge ends. The curved surface can be concave shaped and the hinge can have a constant width from the first end to an intermediate section and decreasing width from the intermediate section to the second end. The intermediate section on the hinge second end is offset to permit the breaking away of the hinges flush with the base member surface.
