Description

[Detailed description of the invention] [Industrial application field] This invention relates to an insulating bag for carrying small items that can be stored and carried without being affected by temperature.

[Conventional technology]

Conventionally, cooler bags and portable insulating bags that closely cover the outer periphery of the container have been generally known as insulating containers that preserve the temperature of the contents without being affected by the outside temperature for a relatively long period of time. There is.

[The problem that the idea aims to solve]

Cooler bags, also known as portable insulated containers, form rigid containers and are inconvenient for storing small items or small amounts of temperature-maintaining items, and small insulated containers are In addition to prohibiting the mixing of small items in addition to containers,
Since the method of tying the opening with string is adopted, there is a drawback that the insulation effect is low.

This idea was developed to compensate for the above drawbacks; it is smaller than a cooler bag, larger than a small insulated bag dedicated to a specific container, and can hold multiple contents of an unspecified shape according to their collective form. The purpose of this invention is to provide a flexible, medium-sized insulating bag that accommodates the needs of the user.

[Means for solving the problem] In order to achieve the above object, a heat insulating sheet made of a thin urethane foam sheet with an aluminum sheet attached to one side is used as the material, and the aluminum sheet side is placed inside to form the inner bag. In addition, the aluminum sheet surface is turned outward to form the outer bag, and the inner bag and the urethane foam sheet of the outer bag are polymerized to form the main part of the double inner and outer bag body. The inner bag and the outer bag are branched from the upper part of the main part of the bag so as to release the superimposed relationship between them, and a fold line is formed on the exposed surface of the urethane foam sheet between the outer surface of the independent inner bag and the inner surface of the outer bag. An independent inner bag is formed by covering a double-folded aluminum sheet with a valley part with the fold line in contact with the branch part, a urethane foam sheet as the middle layer, and covering both the front and back sides with aluminum sheets, and having the same structure as the inner bag. The bag body is formed by sewing the independent inner bag, the periphery of the outer bag, and the periphery of the main part of the bag so that the height is higher than that of the independent outer bag. Hook-and-loop fasteners are installed on the inside of the lid part extending from one side of the opening of the bag and on the outside of the other side, and the opening end of the outer bag is located at a lower position than the opening end of the inner bag. It consists of male and female hooks installed on the inside.

[Effect]

At the top of the main part of the bag, which has a double structure, there is an inner bag that is formed independently by covering the front and back sides with aluminum sheets so that the middle layer is urethane foam, and an outer bag that has the same structure as the inner bag and is branched and independent. ,
After inserting the desired object into the main part of the bag through the inner bag of the former, fold back the lid part of the independent inner bag, and join the hook-and-loop fastener provided there to the hook-and-loop fastener attached to the outer surface of the other side; The independent inner bag thus closed is folded and folded into an independent outer bag, and the male and female hooks provided at the opening of the outer bag are fastened to close the bag.

〔Example〕

Next, an embodiment of this invention will be described with reference to the drawings. A heat insulating sheet 3 made of a thin urethane foam 1 with an aluminum sheet 2 pasted on one side is used as the material, and the inner bag 4 is made with the aluminum sheet 2 side inside. In addition, these inner bags 4 are made with the aluminum sheet 2 side facing outside to form an outer bag 5.
The urethane foam sheets 1 and 1 of the heat insulating sheet 3, which will become the outer bag 5, are polymerized to form the main part of the bag with double inner and outer sides. Each is branched so as to release the polymerization relationship with the bag 5, and the crease line 7 is formed at the valley part on the exposed surface of the urethane foam 1, 1 between the outer surface of the inner bag 4 and the inner surface of the outer bag 5, which are independent parts. An independent inner bag 4 is formed by covering a double-folded aluminum sheet 6 with the fold line 7 in contact with the branching part, using the urethane foam sheet 1 as a middle layer, and covering both the front and back sides with aluminum sheets 2 and 6.
The periphery of the independent inner bag 4 and outer bag 5 as well as the periphery of the main part of the bag are sutured so that the height is higher than that of the independent outer bag 5 which has the same structure as the inner bag 4. to form a bag body, and further, an inner bag 4 is formed.
A lid body portion 8 provided by extending one side of the opening of the
A hook-and-loop fastener 10 is installed on the inside of the bag and the outside of the other side, and a male and female hook 9 is installed on the open end of the outer bag 5, which is located at a lower position than the open end of the inner bag 4. .

In this way, the branch point where the inner bag 4 and the outer bag 5 are completely separated is located above the main part of the bag formed by polymerizing the urethane foam sheets 1 of the two heat insulating sheets 3. The exposed surface and the joint surface thereof are opened, and the surface of the urethane foam sheet 1 of the inner bag 4 and outer bag 5 to be separated is covered with an aluminum sheet 6 made of the same material as the aluminum sheet 2 on the other side. In order to reverse the process, the aluminum sheet 6 is folded in half so that the fold line 7 becomes the bottom of the valley, and the joint end formed by the branching of the urethane foam sheets 1 is closed at the seven fold lines, and , the two-winged portions are joined so as to cover the exposed surfaces of the urethane foam sheets 1, 1 in the inner bag 4 and outer bag 5. In this way,
Each independently uses a urethane foam sheet 1 as the middle layer and an aluminum sheet 2 on both sides of the middle layer.
The height of the inner bag 4 and the outer bag 5 covered with the outer bag 6 is such that the height of the inner bag 4 is, for example, about 3 cm higher than the upper end of the outer bag 5 excluding the lid part 8. 5
The length of the independent part is, for example, 7 cm, which can be inserted by closing the opening of the independent inner bag 4 and folding it in half.
It is considered to be the highest rank. In this way, the hook-and-loop fastener 10 described above is attached to the predetermined position of the opening of the inner bag 4.
In addition, the above-mentioned male and female hooks 9 are attached to predetermined positions of the opening of the outer bag 5.

Note that the reference numeral 11 in the figure indicates a hand.

[Effect of idea]

As described above, this invention is a heat-insulating bag that is intended to be a flexible and medium-sized carrying bag that requires heat retention. The two sheets of sheet 3 have a double structure in which one side of the urethane foam sheet is polymerized to strengthen its insulation effect and flexibility.
Each of the two superposed heat insulating sheets 3 at the top of the main part of the bag is branched and independently formed into an inner bag 4 and an outer bag 5, and in each of these, one aluminum sheet 6 is placed on the exposed surface of the urethane foam sheets 1, 1. The two urethane foam sheets 1, 1 are folded in half to form a crease line 7.
and closes the joint opening by contacting the branch part of the
As a result, the inner bag 4 and the outer bag 5 are constructed with the urethane foam sheet 1 as the middle layer and the front and back surfaces are covered with the aluminum sheets 2 and 6, so that the opening and closing operations of the bags can be performed separately. Since it can be sealed individually, it has a double insulation structure that separates the parts that are most susceptible to the influence of outside temperature, and the main part of the bag has a double structure of the insulation sheet 3 of the above structure, and the middle layer is an aluminum sheet with high thermal conductivity. Heat insulation sheet 3 that was polymerized without bringing in
Separate at the top of the main part of the bag and form urethane foam 1.
