Claims (1)

[Scope of Claim for Utility Model Registration] (1) Exhaust holes and air supply holes are provided at appropriate locations on the container body and lid made of foamed synthetic resin, and one side of each block-shaped support made of foamed elastic material, that is, the exhaust hole. A non-ventilated valve plate is provided on the inside of the container for the air supply hole, and a non-ventilated valve plate is provided on the outside of the container for the air supply hole. A cold storage container for vacuum precooling, which is supported and arranged, and each hole is opened and closed like a check valve by each valve body. (2) An exhaust hole and an air supply hole are provided on the top surface of the lid, and a recess recessed downward in the top surface of the lid communicates with the exhaust hole and the air supply hole and is visible from at least one side edge. A cold storage container for vacuum precooling according to claim 1 of the utility model registration claim, which is formed by forming a vacuum precooling container. (3) An exhaust hole and an air supply hole are provided on the top surface of the lid, and a recess recessed downward in the top surface of the lid is communicated with the exhaust hole and the air supply hole, and from one of the facing side ends to the other. A cold storage container for vacuum precooling according to claim 2 of the utility model registration claim, which is formed for use in vacuum precooling. (4) A notch that opens upward is provided in the side wall of the container body, and a concave groove is formed continuously or intermittently at approximately the center of the side wall in the width direction by communicating with this notch, and a convex groove is provided at the side edge. A cold storage container for vacuum precooling according to claim 1, wherein an auxiliary insertion plate is inserted into the notch by fitting into the recessed groove, and an exhaust hole and an air supply hole are provided in the auxiliary insertion plate. (5) The vacuum precooling cold storage container according to claim 1, which is provided with an exhaust hole and an air supply hole on either the top surface of the lid, the side wall, or the bottom surface of the container body. (6) A cold storage container for vacuum pre-cooling according to claims 1 to 5, which utilizes open-celled support parts as the block-shaped support part. (7) A cold storage container for vacuum pre-cooling according to claims 1 to 5, which utilizes a closed-cell support as the block-shaped support. (8) The vacuum according to claims 1 to 7 of the utility model registration claim, in which the diameter of the air inlet side of each hole is smaller than the inner diameter of the hole body, and the vacuum is opened and closed by a valve plate having a larger diameter than the diameter of the inlet side. Insulated container for pre-cooling. (9) Utility model registration claim No. 1 in which the exhaust hole and/or the air supply hole are sealed with a sealing material after pre-cooling.
A cold storage container for vacuum precooling according to item 8.
