A surgical case cart having a closed container supported on a chassis. The closed container includes a pair of front door panels hinged to side door panels which in turn are hinged to side wall sections, so that the container can be completely opened with the front and portions of the sides being exposed by the door panels wrapping around the side and back. The door panels are formed of single pan construction so as to avoid cracks and crevices, and yet exhibit rigidity of a double pan door construction. The lower edges of the door panels provide a baffle effect to reduce the movement of contaminated air into the cart. The top of the cart contains an overhang lip to prevent liquids from spilling into the container. Stem mounted casters are utilized to avoid flat horizontal surfaces on which dirt can collect. The intersection between the back, sides and chassis is constructed to avoid the possibility of collecting contamination and bacteria. A door latch is provided which indicates whether the contents of the cart are sterile or contaminated. Opening of the cart door panels nevertheless can be accomplished without the use of the operator's hands. The cart construction therefore provides improved sterility, greater accessibility, and brings about easier maintenance.
