2. Description of the Related Art In Japan, the recent development of road traffic networks,
Along with the expansion, home delivery services and parcels that can significantly change the distribution mechanism, from railroad-based transport in the past to quick and thorough transport by truck, enabling flexible transport and delivery according to transport items and destinations Transportation has become popular, and now, in addition to delivery of fresh foods such as vegetables, fruits and marine products, alcoholic beverages such as sake, whiskey, wine, etc., processed foods such as lunch boxes and prepared dishes, as well as injections Transportation and delivery of various products and goods that are not allowed to deteriorate, such as transportation of chemicals such as liquids and reagents, door-to-door sales of soft drinks, and delivery of pizza, etc., while maintaining the best condition. It is being sought and is being implemented by various means.

Up to now, transportation and delivery responding to such needs can be satisfactorily handled by introducing special vehicles equipped with various equipments suitable for the purpose, such as refrigeration equipment, heating, humidifiers, and water tanks. However, in consideration of maintaining quality before and after transportation by these special vehicles, it is a common cargo handling form that target products and goods are handled by enclosing them in special containers for each predetermined amount. . The most typical container is a lightweight, stackable Styrofoam shipping box that excels in heat insulation, has a cushioning function against external forces, and is often used in various fields because it is inexpensive and easy to handle. Although it has achieved its primary purpose, in addition to the inconvenience of collapse during transportation and storage in a stacked state, the empty Styrofoam shipping box before and after transportation must be folded. Not only require storage space, but also require a very large storage space.
When transporting empty boxes as returnable boxes, the large space in the truck bed must be used for this, which has the major problem of increasing transport costs, and is also damaged by dropping or contact during handling. It is easy and durable.

[0004] In view of the above, a case having a structure in which a heat insulating material made of styrene foam is incorporated in a relatively hard synthetic resin housing wall, such as a cooler box for leisure, which is generally widely used, has also been adopted. However, even in this case, similarly, the problem of securing the space when not in use is not solved at all, and instead there is a new problem of increasing the weight, and surprisingly, impact such as dropping, collision, etc. As a result, the outer wall surface made of synthetic resin may be easily deformed or damaged.

[0005] From the viewpoint of such a problem of space and handleability, a cold or heat insulating material in which a urethane foam or a synthetic resin film having an aluminum vapor-deposited layer or the like is stuck in a laminated manner inside a bag made of soft synthetic fibers. Bags are sometimes used, but this type of storage case certainly has a soft and foldable body that allows storage and management in a compact state, but can basically withstand stacking It is not structured, therefore, unless the target product or article is stored in a pressure-resistant container in advance and then put back in a cold or heat-insulated bag with a capacity appropriate for the outer shape of the pressure-resistant container, stacking,
It is almost impossible to achieve the purpose of use, and even if two or three provisional orders are stacked, not only will the stack become extremely unstable, but the lower one will be deformed and collapse easily. Or it may be smashed as it is and crush the stored items, making it unsuitable for a business storage case that is required in large quantities. At present, it is used for individuals for leisure and leisure use.

According to the present invention, as described above, a conventional storage case for carrying out transportation and storage while being able to maintain a state where the influence of temperature from the outside is cut off,
In view of the fact that it has not been improved yet and it has been kept as it was before the old state, it is possible to secure high heat insulation, it can be used in a stack, and in the empty state it is easily folded and miniaturized Judging whether it is possible to realize a useful storage case that leads to more efficient transportation and cost reduction, we quickly started development and research, and conducted trial and error over a long period of time. As a result of repeating prototypes and experiments, this time it is finally foldable, and when assembled in a box shape, it can secure enough strength for stacking and has a new structure with excellent heat insulation The storage case has been successfully realized, and the configuration will be described in detail below, together with some embodiments representing the present invention shown in the drawings.
