Claim 12

The tray of claim 9 wherein the cover lid pivots to an open position such that the respective side cover wall is substantially positioned between the bottom surface of the base wall and a respective foot member of the pedestal.

Claim 13

The tray of claim 8 wherein the guide follower pin rests in the low region of the guide slot when the cover lid is in a closed position.

Claim 14

Claim 15

The tray of claim 13 wherein the retainer comprises a block of shock absorbent material having at least one hole extending therethrough for receiving a specimen containing vial.

Claim 16

The tray of claim 1 wherein upper edges of the tray portion have a shoulder forming an inwardly offset rim, the cover lids surrounding the rim and overlying the shoulder in a closed position.

Claim 17

The tray of claim 1 wherein the cover lids are formed from a transparent material such that a medical technician or laboratory assistant can view the vials through the cover lids to determine whether any leakage or spillage had occurred before the cover lids are opened.

Claim 18

A biological vial transport tray comprising: a tray portion having a base wall, a plurality of end walls and a plurality of side walls, the base wall having a bottom surface and a top surface, the end walls and side walls forming a rim around the tray portion; a pedestal attached to the bottom surface of the base wall for supporting the tray portion on a supporting surface, the pedestal including a leg having a first end portion and a second end portion, the first end portion being attached to the bottom surface of the base wall whereby the leg projects from the base wall in the direction opposite the center handle; a pair of cover lids, each cover lid having a pair of end cover walls, a top cover wall, a side cover wall and a plurality of arms, the cover lids resting on the rim when the cover lids are in a closed position, and cam followers mounted on and extending downwardly from the end cover walls; and guide means connected to the end wall of the tray portion for receiving the cam followers guiding movement of the cover lid between an open position and the closed position, the guide means comprising a cam guide slot recessed into the end walls of the tray portion, the cam guide slot comprising an elongated slot extending in directions between the side walls and wherein the guide slot has a low region in the portion of the slot which is spaced a greater distance downwardly from the rim than of the guide.

Claim 19

A biological vial transport tray comprising: a tray portion having a base wall, a plurality of end walls and a plurality of side walls, the base wall having a bottom surface and a top surface, the end walls and side walls forming a rim around the tray portion; a pedestal attached to the bottom surface of the base wall for supporting the tray portion on a supporting surface, the pedestal including a leg having a first end portion and a second end portion, the first end portion being attached to the bottom surface of the base wall whereby the leg projects from the base wall in the direction opposite the center handle; a pair of cover lids, each cover lid having a pair of end cover walls, a top cover wall, a side cover wall and a plurality of arms, the cover lids resting on the rim when the cover lids are in a closed position, and cam followers mounted on and extending downwardly from the end cover walls; and guide means connected to the end wall of the tray portion for receiving the cam followers guiding movement of the cover lid between an open position and the closed position, the guide means comprising a cam guide slot recessed into the end walls of the tray portion, the cam guide slot comprising an elongated slot extending in directions between the side walls and wherein the guide slot has a low region in the portion of the slot which is spaced a greater distance downwardly from the rim than of the guide.
