<P>PROBLEM TO BE SOLVED: To provide a cooling tray which can properly ensure close contact between a cold storage agent container and a metal plate by suppressing the deformation of the cold storage agent container formed of a synthetic resin. <P>SOLUTION: The cooling tray is configured by sealing a cold storage agent in a hollow box-shaped cold storage agent container 1 formed of a synthetic resin. The cold storage agent container 1 is molded by insert blow-molding with a metal plate M buried in the upper wall 10 thereof. The metal plate M has a plurality of recessed parts M1 on its peripheral edges, and is buried in the upper wall 10 with its top face partially exposed to the outside. The upper wall 10 includes an upper face support 12 covering the upper face peripheral edge of the metal plate M, a lower face support covering the lower face of the metal plate M, and a side face support covering the side faces of the metal plate M and connecting the upper face support 12 to the lower face support. The side face support comprises a first side face support covering outside faces of the metal plate M and a second side face support covering inner faces of the recessed parts M1 of the metal plate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
