Abstract

(57) [Summary] [PROBLEMS] To provide a cloth bag for lunch having a high heat retaining function. SOLUTION: A two-layered bag body is formed of a thick cloth, a lunch box is stored in an upper part, a heat insulator such as a heating material can be stored and removed in a lower part, and the lunch box can be stored and taken out by using a heat insulator nearby. You can keep warm and eat a warm lunch.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a packing bag for a lunch box, and more particularly, to a cloth bag for a lunch box having heat insulation.

[0002]

[Prior art]

 There is an electronic jar in the storage case for keeping the lunch box warm. There is also a lunch bag made of a material having heat insulation properties, but there is no cloth lunch bag made of a material having excellent heat insulation properties.

[0003]

[Problems to be solved by the invention]

 Warm food is better for daily lunches and lunches to bring with you. They want to eat warm lunches, especially in cold weather. However, conventional electronic jars, which are lunch boxes for heat insulation, are excellent in heat insulation, but are bulky, heavy, and require simplicity. It is extremely inconvenient to bring it to work or school as a daily lunch.

On the other hand, there is a bag made of a thick cloth such as a quilted fabric or a bag made of a material having heat insulating properties, but lacks heat insulation properties.

Accordingly, an object of the present invention is to provide a cloth lunch bag having a high heat retaining function.

[0006]

[Means for Solving the Problems]

 The fabric lunch bag is formed in a two-layer structure, and the lower layer is a heat insulator storage unit that stores a portable heat insulator such as a heating material.

[0007]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a quilted thick cloth bag which has a wide opening at an upper portion and has a so-called drawstring type in which an entrance is fastened with a string 3 or the like. The reason why the bag 1 is of the drawstring type is that it can be easily stored and taken out regardless of the size of the lunch box. If it is a double-layered cloth bag, it is not particularly limited to the drawstring type.

Further, the material is not limited to the quilted fabric, but may be another thick fabric having heat insulation.

[0010] At the bottom of the cloth bag 1, a heat insulator storage unit 2 for housing the heat insulator 7 is integrally formed. A fastener 4 is attached to the storage section 2, and the fastener 4 is opened and closed by an opening / closing tool 5. The opening / closing means of the storage unit 2 may be a fastener other than a fastener, a planar fastener, a snap, or the like.

[0011] With regard to a lunch bag using the planar fastener 8, opening and closing with the fastener can more reliably store the heat retaining body, but in some cases, it is more suitable in terms of manufacturing cost.

The heat insulator 7 is a portable heat insulator such as a heating material, and is preferably a disposable portable warmer represented by Hokalon (trademark) or the like. A disposable body warmer is inexpensive at about 20 to 30 yen per piece, but if it is uneconomical and inconvenient to generate garbage, a heat insulator using a heating agent that can be heated in a microwave oven and used semi-permanently is also commercially available. You can use this because it is.

The heat insulator 7 is placed in the heat insulator storage section 2 provided at the bottom of the lunch bag 1, the fastener 4 is closed and stored, and the lunch box 6 is stored from the opening 1 a. The lunch box 6 is heated from the bottom by the heat insulator 7 for a long time and can eat warm rice and side dishes.

After finishing the lunch, the heat insulator 7 can be taken out of the heat insulator storage unit 2 and discarded, or if the heat insulator is still warm, it can be used to keep the body warm. .

Next, another embodiment of the present invention will be described with reference to FIG. In FIG. 2, reference numeral 9 denotes a thick quilted cloth bag. It is a so-called drawstring-type bag that can be opened wide at the top and the entrance is tied up with a string 13 or the like. At the bottom of the cloth bag 9, a heat insulator storage unit 10 for housing the heat insulator 12 is integrally formed. The male and female of the planar fastener 8 are sewn or adhered to the inner bottom surface and the upper surface of the heat retaining body storage part 10, respectively. The heat insulator 12 is a portable heat insulator such as a heating material. The heat insulator 12 is placed in the heat insulator storage section 10 provided at the bottom of the lunch bag 9, the planar fastener 8 is closed and stored, and the lunch box 11 is stored from the opening.

[0016]

[Effect of the invention]

 In a simple way, lunch can be eaten while it is warm, and it is light and convenient to carry.

Since the conventional lunch bag is formed in a two-layer structure, the production is simple and the cost is low.

[0018] It is convenient to be able to use a heat insulator that is nearby.

[Correction contents]

The heat insulator 7 is put into the heat insulator storage section 2 provided at the bottom of the lunch bag 1, the fastener 4 is closed and stored, and the lunch box 6 is stored through the opening 1 a. The lunch box 6 is warmed from the bottom by the heat insulator 7 for a long time and can eat warm rice and side dishes. In the figure, reference numeral 14 denotes a ventilation hole provided in the heat retaining body storage section 2. The ventilation hole 14 is also provided in the heat retaining body storage section 10 of FIG.
