Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention makes it possible to carry and carry light meals such as lunch boxes and sandwiches and cosmetics without being affected by the temperature of the season or the temperature of the outside air, keeping warm things warm and cold things cold, and carrying them around. It's about the back.

[0002]

[Prior art]

 Conventionally, this type of bag includes a bag for lunch boxes simply made of woven or non-woven fabric, and a silver bag bag made of aluminum with an aluminum film deposited on foamed polyethylene. In addition, there is a box-shaped cool bag using styrene foam or the like.

[0003]

[Problems to be solved by the device]

 However, since the above-mentioned conventional bag for lunch has no effect of keeping cold and warm, the contents in the bag become cold and hard in the cold season, and the contents in the bag become rotten in the hot season. It was very inconvenient because it was lost.

In addition, since the aluminum-colored polyethylene bag with aluminum vapor-deposited has the silver-colored surface of the aluminum exposed to the outside as it is, it does not hinder the outdoors or everyday grocery shopping, where practicality is important. , I don't like to carry around in the city, on the train or office. In particular, it is not used at all because it does not match the tastes of modern people who value the environment, atmosphere, and aesthetic balance with people's clothes. Even if the surface aluminum is coated with a polyester film, the metallic feel of the surface, which is cold, is disliked. Also, in cold and hot seasons, aluminum vapor-deposited polyethylene alone is not enough to keep cold and warm.

Further, the cold insulation bag using styrofoam has a great drawback that it is inconvenient to carry and it becomes an obstacle especially when nothing is put inside.

[0006]

[Means for Solving the Problems]

 The present invention is intended to solve the above-mentioned problems, and while the outer bag (Fig. 4) of the bag is adapted to various tastes and personalities of an individual, the contents of the bag can be adjusted according to seasonal temperature and temperature. Made of multiple materials that are not easily affected by changes. In addition, in order to obtain a higher heat insulation effect, a pocket (10) for putting a heat insulation agent or a disposable warmer etc. is provided in the bag so that it can be used together with the heat insulation agent or heat insulation agent (9). In addition, the material and design are foldable so that it can be easily carried when the bag is not used.

First, the bag has at least a double structure of an outer bag (FIG. 4) and an inner bag (FIG. 3). Woven or non-woven fabric (1) is used as the material for the outer bag, and materials such as ordinary handbags and bags with designs, patterns and colors (2) that suit various tastes are used. The inner bag uses foamed polyethylene (6) with evaporated aluminum to keep the bag cool and warm. If necessary, the structure of the bag should be triple or quadruple with additional heat insulating material to obtain a higher heat insulation effect.

[0008] A heat insulating agent (9) such as a cold insulating agent or a disposable warmer is used by one to several pieces depending on the effect of keeping the cold and the heat and the time of use.

The outer bag (FIG. 4) and the inner bag (FIG. 3) do not necessarily need to be sewn together or bonded with an adhesive, and may have a structure that allows them to be separated. Rather, it is more convenient to have a structure that can be separated when washing and drying the bag. In that case, a velcro tape (11), a fastener, a flock or a double-sided tape may be used to bond the outer bag and the inner bag.

The woven / nonwoven fabric (1) may be quilted and used.

Further, in order to protect the surfaces of the aluminum film (4) and the foamed polyethylene (6) and prevent scratches, the surfaces of the aluminum film and the foamed polyethylene (polyethylene film (7) and polyester film ( You may use the thing coated by 8).

When vapor-depositing the aluminum film (4) and the foamed polyethylene (6), a reinforcing fiber (5) is used, and an aluminum vapor-deposited polyethylene (3) having increased strength may be used.

[0013]

[Action]

 Since the bag of the present invention is configured as described above, it is possible to keep the contents in the bag at a constant temperature, with little influence of seasonal heat and cold or changes in the temperature of the outside air.

The outer bag of the bag (FIG. 4) is made of woven or non-woven fabric (1), and its design, pattern and color (2) have the appearance of a normal handbag or bag, You can carry the bag as it is in your new seat or anywhere. Since the inner bag of the bag (Fig. 3) is made of aluminum-deposited polyethylene (3), it is possible to keep the heat and cold inside the bag for a long time.

In addition, a heat insulating agent (9) such as a pocket warmer (10) provided in the inner bag (FIG. 3) of the bag or a disposable body warmer has an effect of keeping the inside of the bag cold and warm. It is effective in raising the temperature and maintaining a constant temperature for a long time.

【Example】

 Hereinafter, embodiments will be described with reference to the drawings.

FIG. 1 is a schematic perspective view of a bag, in which a woven / nonwoven fabric (1) having a design, a pattern and a color (2) is used as an outer bag, and an aluminum-deposited polyethylene (3) is used as an inner bag. The bag is equipped with a pocket (10) and the pocket is filled with a cooling agent or a warming agent (9) so that the temperature inside the bag is kept constant for as long as possible.

The bag is composed of an outer bag (FIG. 4) and an inner bag (FIG. 3) having a minimum double structure. If necessary, a heat insulating material may be added to form a triple or quadruple structure.

At 7:00 in the morning, put the lunch box in the inner bag of the bag, put one heat insulating agent in the pocket, close the mouth of the bag, let the workers carry it when commuting, and open it at noon after about 5 hours. However, the bento was kept warm.

Similarly, the sandwich and one ice pack were put in and opened about 5 hours later at noon, but the lettuce and ingredients of the sandwich were not damaged and were kept in a moderately cold state.

FIG. 2 is a cross-sectional view of the outer bag and the inner bag of the bag. The outer bag is made of a woven / nonwoven fabric (1) having a design, a pattern and a color (2). The inner bag is made of aluminum vapor-deposited polyethylene (3) obtained by vapor-depositing an aluminum film (4) on foamed polyethylene (6), using reinforcing fibers (5) between the aluminum film and the foamed polyethylene, and For protection, the outer surface of aluminum is coated with a polyester film (8) and the outer surface of expanded polyethylene is coated with a polyethylene film (7). The suitable thickness of the foamed polyethylene (3) is usually about 0.5 mm to 3 mm.

Furthermore, when the thickness of the foamed polyethylene (6) of the aluminum vapor-deposited polyethylene was doubled and tripled, it was a little bulkier than the thin foamed polyethylene, but higher cooling and heat retaining effects were obtained.

Further, when the expanded polyethylene (6) having a double thickness and two or more cold insulation agents or heat insulation agents (9) were used, a longer cold insulation / heat insulation effect was obtained.

It should be noted that the ice pack (9) is economical because it can be put in the refrigerator again after returning home and used again the next morning.

FIG. 3 shows an inner bag of a bag, which is made of aluminum vapor-deposited polyethylene (3) and has a pocket (10) for storing a cold insulating agent and a heat insulating agent (9).

FIG. 4 shows an outer bag of the bag, which is made of a woven / nonwoven fabric (1) having a design, a pattern and a color (2), and a velcro ( Since it uses 11), the outer bag can be freely removed.

[Effect of device]

 As mentioned in the example, the lunch box was placed in the inner bag of the bag at 7:00 in the morning, one heat insulating agent was put in the pocket, the mouth of the bag was closed, and the bag was carried at work. It was opened at noon a few hours later, but the bento was kept warm.

Similarly, the sandwich and one ice pack were put therein and opened about 5 hours later at noon, but the lettuce and the ingredients of the sandwich were not damaged and were kept in a moderately cold state.

Therefore, it was not necessary to reheat the bento using a microwave oven at the time of a meal or to keep the bento in the refrigerator until the meal time so as not to be damaged.

Furthermore, I used a bag with a different pattern on the outer bag and carried it in my hand when commuting, but there was almost no discomfort, and it looked like a normal bag on the train or in the city and was comfortable. It was

Also, using a bag with an outer bag having a different pattern and shape, each of three male and female students of elementary school, junior high school, and high school carried it to the school, but from the appearance it was a lunch box bag. Since it was indistinguishable, it was not disliked not only by the girls but also by the boys who brought them.

I asked a young woman working in an urban company to carry a bag with sandwiches and rice balls along with my handbag when I commute to work, but I was happy to carry it because the design of the outer bag was good. When I left the company, I could fold the bag and put it in my handbag, so there was no problem with dating or shopping after leaving the company.
