BACKGROUND OF THE INVENTION
The present invention relates to a foldable heat insulating container suitable for delivering food or the like that needs to be kept cold.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a foldable heat insulating cold container used for delivering food or the like while being kept cold or warm has been known. Such a heat-retaining container is a box that can store food when the food is delivered, and can be folded back compactly after the delivery is completed. An example of this type of heat insulation container is disclosed in Japanese Patent Application Laid-Open No. 10-287372.
[0003]
As shown in FIG. 4, a heat insulation and cooling container 50 disclosed in Japanese Patent Laid-Open No. 10-287372 is folded inward when the container body 51 is folded in an inverted V shape, and when the bottom 52 is folded inward. It has a pair of opposite side wall parts 53 and 54 provided with possible bending parts 58 and a pair of side wall parts 55 and 56 parallel to the bent parts of the bottom part 53.
[0004]
Further, in the heat insulating and keeping container 50, the heat insulating panels 61 and 62 are always placed on the pair of side wall portions 55 and 56, respectively, and when the container body is folded, the heat insulating panel 63 is superposed on the heat insulating panel 61. The heat insulation panels 64a, 64b, 65a, 65b are connected to the respective vertical end edges of the heat insulation panel 62 in a folding state when folding the container body. .
[0005]
Furthermore, in the heat insulating cold container 50, the heat insulating panel 63 arranged to overlap the heat insulating panel 61 is tilted to the bottom 52 in a state where the container is expanded to be a box shape, and becomes a heat insulating panel at the bottom. The heat insulation panels 64a, 64b, 65a, 65b connected to each of the vertical end edges of the heat insulation panel 62 are folded like a folding screen when the container is folded. In the state which became, it becomes a heat insulation panel of the side wall parts 53 and 54.
In FIG. 4, reference numeral 71 denotes a lid portion, 72 denotes a bent portion provided on the lid portion, and 73 and 74 denote heat insulating panels.
[0006]
[Problems to be solved by the invention]
Although the above-described heat and cold container 50 is box-shaped when delivering food or the like, it can be folded after the delivery of food or the like, so that it is a suitable container for delivering food or the like.
However, since the heat insulation cold container 50 is integrally formed with the heat insulation panel and the flexible container body, there are problems that the structure is complicated and the manufacturing process is complicated and expensive. In addition, since the heat insulation panels are joined together and the heat insulation panel and the container are integrated, there is a problem that it is not easy to replace the heat insulation panel when the heat insulation panel is damaged or contaminated. . Moreover, since the size of the heat insulation panel used is constant, the heat insulation characteristic is also constant, and there is a problem that the heat insulation characteristic corresponding to the requirement of the article to be stored cannot be selected. That is, it is inconvenient because it is impossible to change the number of heat insulating panels or use heat insulating panels having different thicknesses as appropriate.
[0007]
The present invention solves the problems of the conventional insulated container as described above, so that the heat insulating plate can be replaced, and the number and thickness of the heat insulating plates are appropriately selected according to the characteristics of the food to be stored. It is another object of the present invention to provide a heat-retaining and cold-retaining container that can be manufactured and that is simple and inexpensive to manufacture.
[0008]
