[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is used as a shopping bag, a carrying bag, and a general bag, and foods such as sashimi, mentaiko, and cake that require refrigeration, frozen foods, and foods that need to be kept cold, such as bento and pizza, are kept warm. The present invention relates to a box bag with a handle suitable for storing foods and the like that need to be maintained.

[0002]

[Prior art]

 A conventional box bag with a handle has a structure in which a pair of handles are arranged side by side along the opening periphery of the front and back of the bag. Further, the structure of this handle is such that an annular grip portion is integrally formed on the upper edges of the horizontally long mounting plates which are mounted along the inner surfaces of the front opening peripheral edge and the back opening peripheral edge of the bag, respectively. In a conventional box bag with a handle, the side surface of the bag that folds inward when the bag opening is closed is located between the pair of handle mounting plates. Therefore, there is a problem that the opening of the bag cannot be closed without a gap. For this reason, when the refrigerated / warm items are stored because the air inside the bag cannot be shut off, cold air / warm air easily escapes from the inside of the bag, making it difficult to store them in a cold / heat-retaining state. .

[0003]

[Problems to be solved by the device]

 The first problem to be solved by the present invention is to solve these problems in the past and to close the opening of the bag without any gaps, and even when storing frozen / refrigerated or warm items. It is an object of the present invention to provide a box bag with a handle that makes it possible to prevent cold air and warm air inside from escaping to the outside of the bag and to maintain the cold insulation and heat retention. The second issue is to improve the heat insulation by the heat insulation layer, and to improve the cold insulation and heat retention. The third problem is that the fabric of the bag is waterproof, and it is possible to store the product or soup that causes dew condensation. The fourth problem is to provide cushioning properties for the bag to protect the contained items from impact. A fifth problem is to provide a pocket for accommodating the cold-preserving agent / heat-retaining agent so as to prevent the cold-retaining agent / heat-retaining agent from getting in the way when the product is taken in and out.

[0004]

[0005]

[Action]

 According to the present invention, when a pair of handles are detachably attached and the opening of the bag is closed, the side of the bag is folded inward to accommodate the folded portion of the bag when the opening of the bag is closed. Since the space is formed at both ends between the mounting plates in which the pair of mounting plates are in close contact with each other by the groove provided in the mounting plates, the folded portion on the side surface of the bag is accommodated in the space between the mounting plates. , The pair of mounting plates are in contact with each other without any gaps, and the opening of the bag can be closed without any gaps. Therefore, the air in the bag can be shut off, and the bag can be kept cool and warm, so that food that needs refrigeration or frozen food can be stored in a cold state, and hot food can be stored in a warm state. When using a heat-insulating bag material, the cold insulation and heat retention are enhanced. In addition, by putting a cooling agent / heat retaining agent in the bag, it is possible to maintain high cooling ability / heat retaining ability. If the material of the bag is waterproof, it is possible to store dew condensation-caused items and soups, and protect the contained items from rain. Furthermore, the bag does not get wet and the strength of the bag does not decrease. If the material of the bag is cushioning, the bag can absorb the shock and protect the stored items from the shock. If you have a pocket with multiple vents inside the bag, you can store a cooler or heat-retaining agent in this pocket so that the cooler-keeping agent or heat-retaining agent does not get in the way when you take items in and out. Can be taken in and out smoothly.

DETAILED DESCRIPTION OF THE INVENTION In the present invention, a plastic handle is generally used. To make the mounting plate of the handle detachably lock, each mounting plate is provided with a locking rod, and the locking rod is inserted into the other mounting plate at the position facing the locking rod. The one with a locking hole that is locked is a simple structure and is commonly used. It is desirable to use a composite sheet having a rectangular planar shape and a flexible exterior sheet attached to one surface of a heat-insulating sheet that is heat-sealed by heating and has flexibility and waterproofness. As the heat insulating sheet, it is desirable to use a foamed sheet or an air mat provided with a large number of independent air bubbles inside. As the former foamed sheet, Literon (trademark), Miramat (trademark), and Minafoam (trademark), which are non-crosslinked highly foamed polyethylene sheets, are generally used. As the exterior sheet, a non-woven fabric that is easy to print is generally used. Nonwoven fabrics include natural fibers and synthetic fibers such as polyethylene, nylon, polyester and polypropylene. There are two types of exterior sheets: waterproof type and non-waterproof type. Furthermore, the exterior sheet may or may not have cushioning properties.

[Effect of the invention]

 According to the present invention, it is possible to easily and securely close the opening of the box bag without any gaps, so that even when storing food that requires refrigeration, frozen food, warm items, etc., cold air does not escape and warm air does not escape. It was possible to keep it inside and to improve the cold insulation and heat retention. In addition, the use of a cooling agent / heat insulating agent can improve the cold insulating power / heat insulating power. Therefore, it has become a box bag suitable for storing foods that require refrigeration, frozen foods, warm items, and the like. The use of a heat-insulating bag material made it possible to maintain the cold insulation and heat retention for a long time. In addition, when a cooling agent or a heat retaining agent is used, these losses can be reduced and the economical efficiency can be improved. When a waterproof bag cloth is used, it becomes possible to store items and soups that tend to cause dew condensation, and the items to be stored become wider. Moreover, even if the box bag gets wet due to rain or the like, it is possible to reliably prevent the contained items from getting wet, which improves usability. When a cushioning bag material is used, the box bag absorbs external shocks and protects the stored items from shocks.
