Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an insulated 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 and other items at the consumer's end. 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, in the case of seafood and cooking ingredients, etc., the method used was to store them in containers in a frozen or cooled state and then fill them with dry ice, cold storage agents, and ice necessary for delivery to the destination. has been done.

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, if you try to prevent this by packing excessive dry ice, etc., the storage efficiency will decrease accordingly.
Causes cost increase.

Therefore, to compensate for these shortcomings, seafood, vegetables, fruit cooking ingredients, etc. are often transported using refrigerated trucks or refrigerated trucks to maintain a cold or frozen state depending on the destination, purpose, distance, etc. 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even in this case, cooling is performed from the outside of the sealed cold container, and since the cold container is originally made of insulating material, the cooling effect is very poor, and depending on the transportation distance and time, the container may Cases often occur where only the outer periphery is cooled and the contents are not cooled either, and the original purpose of the refrigerated truck 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.

As such, complicated transportation routes and, for example, collecting frozen foods from a large number of individuals and delivering them to multiple destinations while safely and reliably maintaining the frozen state are inconvenient in terms of cost, equipment, and transportation systems. It is possible.

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 of the present invention immediately responded to the above-mentioned situation and worked diligently on research to alleviate the problem, and as a result, the inventor of the present invention was able to quickly respond to the above-mentioned situation and make efforts in research to alleviate the problem. 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 a refrigerated vehicle or freezer to let cool air into the container. By adopting a method in which the contents are cooled by cooling the contents, and the window is closed during other periods of collection and sorting, and cool air is sealed inside the container, the above problems can be solved at once, and maximum storage efficiency can be achieved. We discovered that perishables could be delivered in a fresh state, and proposed a foamed synthetic resin container that was inexpensive, simple in structure, and highly workable. (Patent Application No. 61-270394, etc.) (Problem to be solved by the invention) However, in the container according to the above proposal, the door for opening and closing the window and the handle part for holding the container when carrying the container are separate from each other. Therefore, during work, two steps were required: opening and closing the window and lifting it up. As a result, people often forget to open and close the door, and there was a concern that this would hinder the delivery of perishables.

The purpose of this invention is to eliminate such concerns and to make it possible to perform both tasks at once by using the door and handle to ensure the opening and closing of the window, thereby making it possible to perform the task reliably. be.

(Means for Solving the Problems) That is, the feature of the present invention that meets the above object is that in an insulated container consisting of a lid made of foamed synthetic resin and a container body, at least the opposing surfaces of the container body are A window is formed on the side wall or between the upper surface of the side wall and the lower surface of the lid body, and a door for opening and closing the window is provided on the outer surface of the side wall and is slidable up and down along the side wall. Moreover, the door also serves as a handle, and the window portion can be closed at the same time by lifting the lower surface of the door.

The lid, container main body, and door of the present invention are all molded shells made of foamed synthetic resin, and examples of the foamed synthetic resin include polyolefin resins such as polystyrene, polyethylene, and polypropylene, and polyurethane resins.

(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) Terminal sorting (windows open) → refrigerated transport vehicles (windows open) → When delivering through the delivery process, the windows are opened during the collection store and refrigerated transport vehicle processes. Place it in the refrigerator or freezer and let cool air in through the window to keep the perishables 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 kept under heat insulation.

In each of the operations described above, the container of this invention is loaded into a refrigerated transport vehicle and removed from a refrigerator.
In the former case, the door is carried by holding the bottom surface of the door, and the door slides upward, at the same time completing the transition to the closed state of the window, and then opening the window while storing the product inside the refrigerator.

On the other hand, when taking out the container from the refrigerator, by holding the bottom of the door, the door moves upward at the same time, closing the window and shutting off the container from outside air to maintain cool air inside the container during terminal sorting.

Thus, according to the present invention, perishable products can be delivered to remote locations while maintaining their freshness, without the need to close the window, especially in a two-step operation, thereby ensuring that the window can be opened and closed.
