Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a foamed synthetic resin container, and further relates to a foamed synthetic resin container.
< refers to a foamed synthetic resin container equipped with a window that allows easy and reliable opening and closing of cold or warm air.

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

Typical examples include delivering local specialties such as seafood, vegetables, and fruits to consumers while preserving their freshness, and stocking ingredients for dinner, etc. There are packaging and transportation containers for home delivery that sell freshness, such as those that can be cooked in a microwave oven, and those that are processed and seasoned so that consumers can simply heat them in a microwave oven.

In the case of seafood, cooking ingredients, etc., a method is adopted in which the container is stored in a frozen state and then filled with dry ice, cold storage agent, and ice necessary for delivery to the target pond. For example, if the delivery takes a longer time than the scheduled time (for example, there is a shortage of ice cream, etc., the quality of the stored items may deteriorate or even rot, resulting in complete failure to complete the delivery process). On the other hand, this can be prevented.
First, if excessive dry ice or the like is packed, the storage efficiency will decrease accordingly, causing an increase in costs.

To compensate for these shortcomings, seafood, vegetables, fruits, cooking ingredients, etc. are often transported using refrigerated trucks or refrigerated trucks to keep them cool or frozen, depending on the destination, purpose, distance, etc. It will be done. However, even in this case, cooling is performed from the outer periphery of the sealed refrigerated container, and since the refrigerated container is originally an insulated container, the cooling effect is very poor, and depending on the transportation distance and time, only the outer periphery of the container is cooled. However, in many cases, the contents are not cooled down, and the original properties of the refrigerated vehicle are not utilized. When placed inside the container, the temperature of the contents rises rapidly. 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 and, for example, collecting frozen foods from a large number of individuals and delivering them to multiple destinations while maintaining the frozen state safely and reliably require cost, equipment, and transportation systems. , it is literally incapable of 1M.

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 becomes 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 the containers are sorted at the terminal. For example, when waiting for cargo to be loaded or during transportation by transport vehicle, open the window in the container to introduce cold air into the container to cool the contents. By adopting a method that closes the window during collection and sorting and seals cold air inside the container, the problems mentioned above can be solved at once. The present inventors have discovered that a foamed synthetic resin container can be delivered that is inexpensive, has a simple structure, is free from malfunctions in window opening/closing, and can be operated unmanned.

That is, the present invention provides an insulated 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 window has a window frame and a window. It consists of a movable plate attached to a frame with an elastic material such as rubber or a spring, and the movable plate is pushed open by a pressing force perpendicular to its plane to form a ventilation hole, and the pressing force The contents include a foamed synthetic resin container with a structure in which, when removed, the movable plate returns to its original position and closes the ventilation hole.

The present invention will be explained based on drawings showing embodiments. Fig. 1 is a perspective view of a container of the present invention, and Fig. 2 is an exploded perspective view of the same. In these figures, the container of the present invention consists of a lid (1) and a container body (11), and windows (21) are provided on opposing side wall surfaces (12) (12゛) of the container body (11).

A part of the cold air introduced from 2') is transferred to the movable plate (41).
It is introduced into the container by passing over the two lower concave portions (46).

Therefore, even if the rotating plate (41) has only a through hole (45) or only a concave portion (46) without a through hole, the purpose can be sufficiently achieved.

In addition, since the movable plate (41) only needs to receive external force in the vertical direction, the bulging portion (44) <44') is not necessarily necessary, and even if the movable plate (41) receives external force directly at the door portion (42) (42'). good.

Furthermore, although FIG. 5 shows the case where both the door parts (42) and (42') receive pressing force, the movable plate (41) has a tapered part (47) (47°) near the back surface. ), even if an external force is applied to either one of the door portions (42) (42°), the movable plate (41) will recede in an inclined state and a ventilation hole will be formed. Furthermore, providing two windows on opposing side wall surfaces is suitable for differential pressure precooling.

The lid, container body, and window of the present invention are made of a foamed synthetic resin, and suitable foamed synthetic resins include polyolefin resins such as polystyrene, polyethylene, and polypropylene, and polyurethane resins.

Moreover, rubber, spring, etc. are suitable as the elastic material used in the present invention. In the present invention, the window portion is not necessarily attached removably; for example, the side surface of the container itself may be used as the window frame.
