Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an insulating container made of foamed synthetic resin for delivering seafood, vegetables, fruits, etc. while preserving their freshness.

(Prior Art) Foamed synthetic resins typified by 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. Packaging for home delivery that sells products that are ready to be cooked, or even processed and seasoned, with the consumer simply needing to heat them in a microwave oven.
There is a shipping container.

By the way, conventionally, when seafood is used as a cooking ingredient, it is stored in a container in a frozen or cooled state, and then shipped using dry ice, which is necessary for shipping to the destination.
The method used is to fill it with cold storage agent and ice.

However, if the delivery takes longer than the scheduled time, for example, there will be a shortage of dry ice, etc., and as a result, the quality of the stored items will deteriorate, and in some cases, they will rot, resulting in a total loss of marketability. Become. On the other hand,
In order to prevent this, if excessive dry ice or the like is packed, the storage efficiency will decrease accordingly and the cost will increase.

Therefore, in order to compensate for these drawbacks, there is a method of transporting seafood, vegetables, fruits, cooking ingredients, etc. by using refrigerated trucks or refrigerated trucks to maintain a cold or frozen state depending on the destination, purpose, distance, etc. Often used.

However, even in this case, cooling is performed from the outside of the sealed cold container, and since the cold container is originally made of insulating material, the cooling effect is very poor, and depending on the transportation distance and time, the container may In many cases, only the outer periphery is cooled and the contents are not cooled either, and the original purpose of the freezer is not being utilized. When placed in an outside atmosphere, 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.

Therefore, 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. It's impossible.

On the other hand, even for vegetables, etc., they are generally delivered to the destination after being stored in a container and pre-cooled, for example by differential pressure pre-cooling. It is inevitable that problems similar to those described above will occur.

Therefore, the inventor immediately responded to the above situation,
We have conducted extensive research to alleviate this problem, and as a result, we have found that, except 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, they are not loaded at the collection store. While waiting for the container to arrive or while being transported in a transport vehicle, the window provided in the container can be easily opened in the built-in refrigerator or freezer to introduce cold air into the container to cool the contents. We discovered that by adopting a method that closes the window during sorting and seals cold air into the container, the above problems can be solved all at once, and perishables can be delivered in a fresh state with maximum storage efficiency. We have now provided a foamed synthetic resin container that is inexpensive, has a simple structure, and can be operated safely and unattended. (Japanese Patent Application No. 61-270394 “Japanese Unexamined Patent Publication No. 125171/1983”)
(Others) (Problems to be solved by the invention) However, when delivering perishable foods using the foamed synthetic resin containers provided above, the windows must be opened and closed each time the vehicle is loaded or unloaded.
That is, each time a refrigerator is put in or taken out, it must be done manually, and as a result, people often forget to open and close it.

However, in the past, automatic detection of such forgetting to open or close the door has not been carried out, and it has not yet been sufficient in terms of safe and reliable work execution.

Therefore, the present invention focuses on this point, and aims to detect the forgetting to close the window and eliminate mistakes in opening and closing the window.

(Means for Solving the Problems) That is, the present invention is characterized by providing a recess in the upper part of the opposing container side wall surface of the insulating container consisting of a lid made of foamed synthetic resin and a container main body. A window is formed by the and lid, and a door is provided on the outer surface of the window to slide vertically along the outer surface of the side wall of the container, and the door can be held against the wall surface of the main body of the container in the window closed position, and The position of at least one of the recesses in the upper part of the wall surface is such that an alarm device is installed on the side-extending wall surface so that it is exposed on the outside when the door is opened and is shielded by the door when the door is closed.

Here, the lid, the container body, and the door of the present invention are all made of foamed synthetic resin moldings, and examples of the foamed synthetic resin include polyolefin-based resins such as polystyrene, polyethylene, and polypropylene, and polyurethane-based resins.

In addition, in the present invention, the alarm installed on one side of the recess is preferably a sound sensor that detects light and emits music, words, etc. This may be installed on either one of the two opposing recesses, but it is preferable to use a sound sensor that detects light and emits music, words, etc. Depending on the orientation of the container, it is more reliable to provide it on both sides.

This alarm is exposed on the outside by holding the door in a downward position when the door is open, and is shielded by the door when the door is closed.

In addition, the door of the above container is closed when carrying the container.
It is also preferable to use a handle portion for holding the container by hand while closing the window.

(Function) According to the configuration of the present invention as described above, fresh foods, etc. are frozen → packaging → (window closed) → collection store (window opened) → cargo (window closed) → refrigerated transport vehicle (window opened) → terminal sorting (windows closed) -> refrigerated transport vehicle (windows open) -> When delivering through the process of home delivery, the refrigerated transport vehicle is placed inside a refrigerator or freezer with the window open during the collection store and refrigerated transport process, and cold air is pumped through the window. Introduced through to keep perishables etc. inside fresh.

On the other hand, at the stage of taking out the containers from the refrigerator or freezer and sorting them into terminals, the windows are closed to block outside air and the fresh foods and the like in the containers are held under heat insulation.

If you forget to close the window in each of the operating steps described above, the alarm is activated, detects the light caused by forgetting to close the window, and issues an alarm to notify you that you have forgotten to close the window, ensuring that the window remains closed. Conversely, when it is in the closed state,
Since no sound is emitted, it signals the transition to the open state of the window.

Thus, according to the present invention, it is possible to securely open and close windows without making mistakes, and to deliver fresh foods to remote locations while maintaining freshness.
