Description

Detailed Description of the Invention: "Industrial Application Field" The present invention relates to a foamed synthetic resin container, and more specifically, parts having independent functions such as an opening/closing window, a viewing window, a thermometer case, a refrigerant case, etc. This invention relates to a multipurpose foamed synthetic resin container that can be used for multiple purposes by replacing these parts, allows setting and management of conditions suitable for stored items, and allows these parts to be used repeatedly. .

"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 home delivery that sell products that are ready to be cooked, or are processed and seasoned, and consumers only need to heat them in a microwave oven to promote their freshness.

In the case of seafood, cooking ingredients, etc., a method is used in which the container is stored in a frozen state and then filled with dry ice or ice necessary for delivery to the destination.

However, in the case of home delivery services that sell freshness and taste as mentioned above, consumer demands are becoming increasingly strict, and it is inevitable that there will be a stronger preference for fresher and more delicious products. In other words, it goes beyond the traditional binary question of whether or not it requires cold storage, and, for example, even if the same dinner dish is served, it depends on the ingredients used and the menu of the dish, or whether the same seafood is served or not. However, depending on the type of fish, the temperature and humidity required to maintain its unique flavor may vary. In such a case, simply provide an opening for pre-cooling, or
Providing a case to store the cold storage agent is not enough to deal with this problem; for example, after pre-cooling, it is necessary to attach a thermometer and hygrometer to manage and maintain the optimal conditions to preserve the flavor. In some cases, it would be extremely convenient if these thermometers and humidity gauges could be attached to the pre-cooling opening instead of the door. In addition, in order to manage and maintain such detailed conditions, it is necessary to check the condition of the contents, and if it is possible to install a viewing window for this purpose in the pre-cooling opening. It's convenient.

On the other hand, vegetables and the like are generally delivered to the destination after being stored in a container and pre-cooled, for example, by differential pressure pre-cooling. In this case as well, there are optimal conditions unique to the vegetable, as mentioned above, and in this case too, the problem occurs due to the respiration and transpiration effects of the cold storage agent case, thermohygrometer case, vegetables, etc. It would be convenient if an adsorbent case or the like could be attached to adsorb various gases (methane gas "!r-) that inhibit this.

However, conventional containers of this kind are usually intended for one-time use and therefore need to be provided at low cost, so they cannot meet the multifunctionality requirements described in Section 2. .

The present invention breaks down the conventional fixed idea in view of this situation, and
By providing a removable opening/closing window and thermometer case, etc., the opening/closing window and thermometer case, etc. can be reused, reducing costs by 100%.■ Adding multifunctionality to a single container, allowing storage items to be easily removed. We have now provided a container that can be transported under optimal conditions.

That is, the present invention provides an insulating container consisting of a lid made of foamed synthetic resin and a container body, including an opening/closing window, a viewing window, a thermometer case, a hygrometer case, an adsorbent case, a moisture absorbent case, a cool storage agent case, and a heat storage agent. case, preservative case, antioxidant case
No. 51, a multi-purpose foamed synthetic resin container is characterized in that it is equipped with detachable parts such as a desiccant case having an independent function.

Suitable foamed synthetic resins of the present invention include polystyrene resins, polyolefin resins such as polyethylene and polypropylene, and polyurethane resins.

A "component having an independent function in itself" (hereinafter referred to as an "independent functional component") of the present invention means that a container equipped with a storage section for the component can be used as is without any modification or auxiliary equipment. Refers to items that can be attached and used repeatedly, and includes, for example, opening/closing windows, viewing windows, thermometer cases, hygrometer cases, cold storage agent cases, heat storage agent cases, preservative cases, antioxidant cases, desiccant cases, etc. . These independent functional parts are also preferably made of foamed synthetic resin.

The independent functional component is removably provided on at least one surface of the container lid and the container body. In the case of differential pressure precooling of vegetables, etc., it is desirable to install two opening/closing windows on opposite side walls to introduce cold air.

As a method for removably providing the independent functional component in a predetermined housing part, for example, four parts or convex parts are provided on the surface of the housing part, and a method in which the convex parts or four parts are provided on the surface of the part and the concave and convex parts are fitted to each other; A suitable method is to provide a frame-shaped storage section and insert the components into the frame.
