[Industrial applications]

 The present invention relates to a heat-insulating foldable container that stores articles to be transported while being kept warm or cooled, and particularly to a heat-insulating foldable container that has a small number of parts, is efficient in assembling work, and is low cost and lightweight.

[0002]

[Prior art]

 As a conventional heat-insulating foldable container, for example, as disclosed in Japanese Utility Model Laid-Open No. 4-97030, there is a heat-insulating plate formed in a casing shape. This adiabatic collapsible container does not create wasted space when the container itself is stored and moved by making it foldable.

[0003]

[Problems to be solved by the device]

 However, in such an adiabatic collapsible container, the connecting member of each adiabatic plate has a special shape, and there is a problem that it takes time and effort to make a connection. In addition, the cost of the container is high and the container is heavy due to the connecting member itself and its weight.

The object of the present invention was devised to eliminate the above-mentioned drawbacks of the conventional products, and the number of parts is small, the assembling work is efficient, the weight is light and the cost is low, and it is used as a container. It provides a heat-insulating foldable container that saves space because it is plate-shaped except when it is used.

[0005]

[Means for Solving the Problems]

 The present invention has been devised in view of the above, and is a heat-insulating foldable container in which a plurality of heat insulating plates having a resin foam as a base material and end portions of the heat insulating plates are connected to form a casing. In this case, the connecting ends of the heat insulating plates to be connected are cut out at an angle of about 90 degrees in total, and the outer surfaces of the connecting ends which are not cut are made of a synthetic resin sheet. Connection, and at least two notches are provided in the entire container in the inner surface on the notched side of the connecting end and in the vicinity of the connecting end. A heat-insulating foldable container characterized in that the outer surfaces thereof are connected by the synthetic resin sheet.

The heat insulating plate according to the present invention is notched at a total angle of about 90 degrees so that the connecting ends of the heat insulating plates, which are the ends of the inner wall when assembled as a container, are connected to each other at a substantially right angle. It can be appropriately selected as long as it has a heat insulating effect, and a foamed synthetic resin is preferably used as the base material, and polyurethane, polyethylene, polypropylene, There are single or composite materials such as polyvinyl chloride, polystyrene, engineering plastics such as nylon. In addition, the length of the heat insulating plate is formed along the entire circumference of the side surface of the container, the synthetic resin sheets are attached to both surfaces of the heat insulating plate, and the heat insulating plate together with the synthetic resin sheet is 90 degrees in total. Of course, it may be formed by cutting out.

[0007] The synthetic resin sheet has flexibility, which functions not only to connect the heat insulating plates to each other but also to function as a hinge between the heat insulating plates. Examples of the material include polyethylene, polypropylene, polyvinyl chloride, engineering plastics such as nylon, etc., or a composite thereof. Further, the synthetic resin sheet may be adhered not only to the ends of the heat insulating plate in order to connect the ends but also to the entire circumference of the side wall of the container to be formed. Needless to say, the heat insulating effect is enhanced by adhering the synthetic resin sheet to the entire circumference of the side wall of the container.

The synthetic resin sheet can be attached to the heat insulating plate by heat fusion or adhesive bonding. When an adhesive is used, it can be appropriately selected as long as it adheres the heat insulating plate and the synthetic resin sheet, but, for example, a cyanoacrylate adhesive is preferable. The adhesive may be provided on one side of the sheet in advance, or may be applied when the synthetic resin sheet is attached.

Note that the shape of the heat insulating plate and the shape and size of the container itself accompanying it can be appropriately selected according to the items to be stored, such as an integrated lid and a separated lid. You can choose.

[0010]

[Action]

 The present invention cuts the connecting end portions at a total angle of about 90 degrees so that the connecting end portions of the heat insulating plates, which are the end portions of the inner wall when assembled as a container, are connected to each other at a substantially right angle. On the other hand, a synthetic resin sheet is adhered as a member for connecting the continuous connection ends to each other, and a container is provided near the continuous connection end on the inner surface of the continuous connection end with a notch. At least two notches are provided in the entire structure, and the outer surfaces of the notched heat insulating plates are connected to each other by the synthetic resin sheet, so that the heat insulating foldable container can be assembled with a small number of parts. It can be efficient, low cost and lightweight.

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing an embodiment of a heat insulating foldable container according to the present invention.

The heat-insulating collapsible container according to the present embodiment has heat-insulating plates 1, 1, ... Based on expanded polypropylene as a base material and end portions 11 for connecting the heat-insulating plates 1, 1 ,. It is an adiabatic folding container that is formed into a box-like shape. The ends 11, 11, ... Of the heat insulating plates 1, 1, ... Are notched at an angle of 45 degrees with respect to each other, so that when the heat insulating plates 1, 1 are formed into a housing shape, the heat insulating plates 1, 1, ... Are connected at a right angle.

The synthetic resin sheets 2 and 2 for connecting the heat insulating plates 1 and 1 are used for connection and hinge. In addition, the connecting end of the heat insulating plate on the floor portion (not shown) and the connecting end of the heat insulating plate on the side wall portion are also cut out from each other and connected at a substantially right angle. Omitted.

Further, as shown in FIG. 2, this heat-insulating foldable container can be made into a substantially plate shape by folding at the notch 14 except when used as a container. Although illustration is omitted, the floor board is housed inside the side wall portion.

In the heat-insulating collapsible container according to this embodiment, since the heat insulating plates are connected to each other by using a lightweight synthetic resin sheet, the number of parts is small, the assembling work is efficient, and the weight and weight are low. It has the effect of saving space because it has a plate shape except when it is used as a container. In addition, since the synthetic resin sheets are placed on most of the outer and inner surfaces of the heat insulating plate, it has a higher heat insulating effect than the conventional heat foldable container.
