Description

  The present invention relates to a cold storage container for storing food products and the like at a low temperature for a long period of time.

  Generally, this type of cold storage container is a cardboard box with an insulating material such as a foamed polystyrene attached to the inside of the cardboard box. What is stored in a sealed manner is known.

A technique related to such a cold container is disclosed in Patent Document 1.
Japanese Patent Laid-Open No. 10-17032

The problem that the problem is trying to solve

  The above-described conventional cold storage container has a structure in which a cold-retained object and a cold-storage object are directly placed in the same space. If you try to replace the cold storage with a new one to preserve fruits, etc. for a long period of time, if you open the lid, the outside air will flow from the opening at once, the inside of the cold storage container will become the same as the outside air temperature, and the cooling efficiency will be reduced Become.

  Accordingly, the present invention has been made to solve such problems, and a cold storage container is provided in a lid that is opened when a cold storage object is taken in and out to prevent inflow of cold air when the cold storage object is replaced. The purpose of this is to increase the cold insulation efficiency and preserve fruits for a long period of time.

Means to solve the problem

  In order to achieve this object, a cold storage container according to the present invention includes a cold box main body for storing a cold object such as a fruit, and a cold storage object for holding the cold object in a lid that seals an opening of the box main body. A structure is provided in which a regenerator storage unit for storing and a vent hole for sending cool air from the regenerator storage unit to the cool box body.

  In addition, a concave hand-held portion for carrying on the side surface of the cold box main body is provided, and a fixed band-hanging portion having a cut shape is provided on both sides of the upper side of the hand-held portion.

  Further, one end is hooked on the fixed band hanging portion and the other end is hooked on the opposite fixed band hanging portion, and the upper surface of the lid and the regenerator storage lid is simultaneously fixed.

  Further, the recording plate is attached to the fixed band.

The invention's effect

  As described above, the cold storage container according to the present invention has a structure in which a regenerator storage lid capable of exchanging only the regenerator is provided in the lid for taking in and out the object to be cooled, so that when the regenerator is replaced, the regenerator Only the storage lid can be opened to change the regenerator. In the meantime, since the object to be cooled does not come into direct contact with the outside air, the temperature rise inside the cold box body can be suppressed, and the long-term storage can be performed without increasing the cooling efficiency and reducing the freshness of the object. In addition, since the lid and the regenerator storage lid can be fixed at the same time by the fixing band, it can be easily and securely sealed. Further, by integrating the fixed band and the recording plate, the operation of attaching the recording plate is simplified. Because it has a convex band on the outer appearance of the cold box body by providing a fixed band hanging part on the concave hand-held part, it has an excellent effect that many cold boxes can be placed even in a limited space It is.

1, 2, and 3 are diagrams showing the present embodiment, which will be described with reference to FIG.
1 is a cold box main body. The cold box main body is molded with polystyrene foam, and the inner wall surface 15 is urethane coated. An opening is provided in the upper part, and a fitting part 11 is provided around the upper surface of the opening. On the side surface, a hand-held portion 9 for carrying is provided in a concave shape. On the upper side of the hand-held portion 9, a fixed band hanging portion 8 is provided on both sides.

  Reference numeral 2 denotes a lid for sealing the opening of the cool box body 1 from above. There is a groove around the bottom surface of the lid 2, and the object to be cooled 14 is sealed by fitting with the fitting part 11 of the cold box main body 1. The lid 2 may be provided with a rubber seal member (not shown) on the outer periphery of the bottom surface in order to improve the sealing performance. A regenerator storage part 5 is provided in a concave shape in the center of the lid 2. The regenerator storage unit 5 stores a regenerator 10 such as a cold storage pack or dry ice that can supply cold air to food to be cooled for a certain period of time and can be periodically replaced. A plurality of vent holes 4 are provided on the bottom surface of the regenerator storage unit 5 so that the cool air can be circulated in the cool box main body 1. Reference numeral 3 denotes a regenerator storage lid. The regenerator material storage lid 3 is provided with a groove portion 7, and the regenerator material 10 can be sealed by fitting the second fitting portion 6 provided inside the regenerator material storage unit 5.

  FIG. 3 shows a fixing band 3 for fixing the lid 2 after the object to be cooled 14 is stored in the cold box main body 1. One end of the fixed band 3 is hooked on the fixed band hook 8 positioned on the upper side of the hand-held portion 9, and the other end is hooked on the opposite fixed band hook 8 via the upper surface of the regenerator storage lid 3. A recording plate 13 is provided on the fixed band 12 so that the product name, harvest date, etc. of the object to be cooled 14 can be described or a label or the like can be attached.

  A method of using the present invention will be described. First, the lid 2 is opened, and the cold object 14 is stored in the cold box main body 1. Next, the lid 2 is closed and sealed. Next, the regenerator material 10 such as a cold storage pack or dry ice is placed in the regenerator material storage unit 5, and the regenerator material storage lid 3 is covered from above and sealed. In this state, the cool air of the regenerator 10 reaches the inside of the cool box main body 1 through the vent holes 4 and the cool object 14 is kept cold. Then, the fixing band 12 is hooked on the fixing band hanging portion 8 to fix the lid 2 and the regenerator storage lid 3.

  When a certain period of time passes and the regenerator 10 is replaced, the regenerator 10 can be replaced by opening only the regenerator storage lid 3. Since the regenerator 10 can be exchanged without opening the lid 2, the temperature rise inside the cold insulation box main body 1 can be suppressed.

  When taking out the object to be cooled 14, the reverse procedure is taken. That is, the fixed band 12 is removed from the fixed band hanging portion 8. Next, the lid 2 is lifted upward to take out the object to be cooled 14.

  The cold box main body 1, the lid 2, and the regenerator storage lid 3 are not limited to the above-mentioned foamed polystyrene, but may be formed of heat insulating plastic or cardboard. Further, the lid 2 and the entire regenerator storage lid 3 may be made of rubber.

  Therefore, according to the cold storage container of the present invention, when the cold storage object 10 is replaced, the cold storage object 10 can be replaced without opening the lid 2, so that the temperature rise inside the cold storage box body 1 can be suppressed. Can be stored for a long period of time without degrading the freshness of the stored object.

It is a perspective view which shows the cold storage container which concerns on this invention. It is AA sectional drawing of FIG. It is a perspective view which shows the use condition of the cold storage container which concerns on this invention.
