Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a foamed synthetic resin container, and more particularly to a foamed synthetic resin container equipped with a window for injecting cold or hot air that can be easily and reliably opened and closed. It is.

"Prior Art and Problems" Conventionally, foamed synthetic resins such as foamed polystyrene have been widely used in various packaging containers, transportation containers, etc. because they have excellent cushioning and heat insulation properties.

Typical examples of this include delivering local specialties such as seafood, vegetables, and fruits to consumers while preserving their freshness, as well as preparing ingredients for dinner, etc., and delivering them to consumers. There are packaging and transportation containers for courier services that promote freshness, such as those that require 111-il processing, and those that are processed and seasoned, and all that the consumer has to do is add pB to them in a microwave oven. .

In the case of seafood and cooking ingredients, a method is used in which the containers are stored in a frozen or cooled state and then filled with dry ice, cold storage agents, and ice necessary for delivery to the destination. . For example, if the delivery takes longer than the scheduled time, there will be a shortage of dry ice, resulting in a decline in the quality of the stored items and, in some cases, spoilage, resulting in a total loss of marketability. . On the other hand, if excessive dry ice or the like is packed in an attempt to prevent this, the storage efficiency will decrease accordingly, causing an increase in costs.

In order to compensate for these shortcomings, seafood, vegetables, fruits, cooking materials, etc. should be transported to different destinations, uses, and distances! Depending on the 1st class, refrigerated trucks or refrigerated trucks are often used to maintain and transport the items in a cold or frozen state. However, even in this case, cooling is performed from the outer periphery of the sealed refrigerated container, and since the refrigerated container is originally made of insulating material, the cooling effect is very poor, and depending on the transportation distance and time, There are many cases where only the refrigerated container is cooled and the contents are not cooled down, and the original characteristics of the refrigerated vehicle are not utilized.
This time, when the container is placed in the outside air after cooling,
This results in disadvantages such as rapid rise in temperature of objects. For this reason, the poor cooling effect is considered to be unavoidable, and the entire cold storage container is cooled.

In this way, complicated transportation routes, such as collecting frozen foods from many individuals and delivering them to many destinations while safely and reliably maintaining the frozen state, are difficult in terms of cost, equipment, and transportation system. is impossible.

On the other hand, vegetables and the like are generally delivered to their destination after being stored in a container and precooled, for example, by differential pressure precooling. In this case as well, if the delivery time is longer than the scheduled delivery time, the same problem as above will occur.

``Means for Solving the Problems'' In view of the above circumstances, the inventors of the present invention have conducted intensive research and found that when the contents are stored, the containers containing the contents are loaded onto transport vehicles, and when they are sorted at the terminal. For example, when waiting for cargo to be loaded at a collection store or while being transported in a transport vehicle, open the window on the container in the built-in refrigerator to introduce cold air into the container to cool the contents. By adopting a method that closes the window and seals cold air inside the container during other than the above-mentioned collection and sorting, the above problems can be solved all at once, and fresh food can be kept in a fresh state with maximum storage efficiency. The inventors have discovered that it is possible to deliver goods, and have come to provide a foamed synthetic resin container that is inexpensive, has a simple structure, is free from malfunctions in opening and closing windows, and can be operated unmanned.

That is, the present invention provides a heat-insulating container comprising a lid made of foamed synthetic resin and a container body, in which a window is provided on at least one surface of the lid or the container body, and the cough window has a window frame and a window.
