Problems solved by technology

[0005] In the storage bag as described above, it is not necessary to use a storage bag with a heat-insulating part for the container having heat-insulating properties. In this case, it is not economical to use a material with a heat insulating part for the entire storage bag for a container that does not have heat insulation

Embodiment 1）

[0032] exist Figure 1~Figure 8 Among them, the lunch box storage bag 1 is equipped with a cylindrical tube portion 2, a bottom portion 3 that closes the bottom surface of the tube portion 2, an open upper port portion 4, and an upper cover portion 5 that opens and closes the upper port portion 4, and the upper port portion The part 4 is provided with an upper upper opening 4A on the upper surface of the cylindrical part 2, and a side opening 4B which is continuous with the front side of the upper opening 4A and is formed by opening a part of the upper side of the cylindrical part 2. The side opening 4B is formed in an oblique manner. Moreover, the storage bag 1 is comprised from flexible sheet materials, such as a base material, and the bottom part 3 and the upper surface cover part 5 are sewn to the cylindrical part 2. In addition, the upper surface cover portion 5 is sewn on the rear side of the upper surface opening portion 4A, and the upper port portion 4 is completely o...

Embodiment 2）

[0054] Other examples will be described below. In addition, the same code|symbol is attached|subjected to the same part as said Example 1, and the detailed description is abbreviate|omitted.

[0055] in such as Figure 9 In the illustrated embodiment 2, the upper extension part 6 is provided on the upper port part 4 side of the cylindrical part 2 , and the lower extension part 6 is provided on the bottom surface part 3 side of the cylindrical part 2 .

[0056] And it can be used in the following manner, that is, when the extension part is stored, the non-heat-insulating containers 13, 13 are stacked and stored, and when the extension part 6 of the lower layer is extended, the container 16 with excellent heat insulation When stacking non-insulated containers 13, when extending the extensions 6, 6 of the upper and lower layers in two layers, the non-insulated containers 13 can be placed in the central non-extended portion 6H in the height direction. Containers 16 and 16 with e...

Abstract

The invention provides a lunch box storage box which can effectively insulate heat for a container with low thermal insulation when used for combining and storing a container with high thermal insulation and the container with low thermal insulation, and also can allow costs to be lowered. In the cylindrical lunch box storage bag (1) having an upper port that can be opened and closed, any of the upper part and the lower part of the cylindrical portion (2) is euqipped with an extension portion (6) that can telescope along the height direction. The extension portion is only formed by a backing material (7), and a non-extension portion (6H) has a thermal insulation portion (8), so if the extension portion of the storage bag is made to telescope, the height of the lunch box storage bag changes, and thus a user can freely combine the stored containers based on dishes of the day. In addition, a container with themal insulation is configured on the backing material of the extension portion and a container without thermal insulation is configured on the non-extension portion with the thermal insulation portion, so that the lunch box storage box with thermal insulation serves the purpose. Moreover, a sliding joint member (9) is adopted to close the extension portion.

Description

technical field [0001] This invention relates to the lunch box storage bag called a lunch box cover, a lunch box cover, etc. Background technique [0002] Conventionally, there is known a lunch box storage bag (for example, Patent Document 1), which has a bag body that holds a plurality of containers arranged in a row on the bottom of the bag, and arranges the bag body in a state where the number of containers arranged is reduced. A surplus space is generated at the end of one side of the alignment direction, and a part of the circumferential direction of the bag body is recessed from the outside to the surplus space throughout the entire height, thereby making the side circumference of the bag shrink in the circumferential direction, and it is possible to use the hand-held belt and the guide The rope freely maintains and releases the depressed state of the bag body. [0003] In addition, among such storage bags, there are also storage bags with a structure in which resin-m...
