The present invention relates to a bag for storing and keeping a container such as a thermos bottle, a water bottle, or a food container, and keeping it at a constant temperature for a long time regardless of the outside temperature or humidity. It is composed of waterproof fabric, inserting new insulation material between inner and outer shells to maximize waterproof, moisture proof and insulation efficiency, and at the upper part, it forms double sealing means consisting of fasteners and zippers to make heat in and out more. It is to provide a thermos and a cooling bag for a thermos bottle by maximizing the thermal insulation and cold storage efficiency by tightly cracking down.

In general, the storage containers such as various thermos, water bottles, lunch boxes, food containers, etc. in a pocket with a handle and the like to carry around, and at the same time the storage was kept warm and cool by the pocket.

In the case of a conventional bag, it is common to simply form a handle made of a string or a band so as to easily carry it, and thus, the inner-shell of the bag in consideration of heat retention and cold storage to minimize deterioration and temperature change of food in the storage container. Insulating material is also used to the inside, and the use of a fastening strap on the upper part or the waist of the pocket or the cover formed of a zipper or the like integrally prevents the storage container from being separated from the outside.

However, in the case of the conventional thermal insulation and cold storage bag, the insulation material interposed between the inner and outer shell phases is generally composed of a single layer of sponge, so that the thermal insulation, that is, the efficiency of thermal insulation and cooling is inferior, and the inner and outer skins are waterproof and Moisture-proof, especially when using a fastening strap as a sealing means in the upper part of the pocket, even if the string is tightened, heat can enter or enter the center, and you can not expect proper heat insulation efficiency. Since there is a problem that can not be expected high insulation efficiency has been urgently required to develop a device that can eliminate the above problems.

Therefore, the present invention has been made to improve the overall problems of the conventional thermal insulation and cold bag as described above, the present design consists of a multi-layer laminated insulation of high-density polyurethane foam between the inner and outer shell phase of the waterproof fabric, The present invention has been completed with the technical problem of devising to provide a thermos and a cooling bag for a thermos bottle with a waterproof and moisture-proof function at the same time to maximize the insulation and cold storage efficiency by forming a sealing means of a double structure of the drawstring and zipper.

1 is a perspective view showing a preferred example of the present invention, Figure 2 is a perspective view of the cover upside down to show the top sealing structure of the bag provided in the present invention, Figure 3 is a cross-sectional configuration of the present invention, Figure 4 is A When the present invention is described in detail as a secondary enlarged cross-sectional view as follows.

The present invention is to store a storage container (K), such as a variety of thermos, water bottles, lunch boxes and containers containing food to configure a bag (1) for warming and cooling at a constant temperature for a long time regardless of the external temperature or humidity In this case, the body 2 of the bag 1 is composed of a double endothelial (3) and the outer shell (4) made of a waterproof fabric, the inner-sheath (3) (4) between the thin layer made of high-density polyurethane foam Insulating material (5) 4 ~ 6 ply is built-in, the upper end of the body (2) formed a tightening strap (6) into the inner-shell (3) (4) inside the clamping strap (6) by tightening holes (7) Let it be.

The cover 4 of the lower portion of the tension strap 6, the upper body 2 is coupled by a coupling means 8, such as a zipper, and constitutes a cover 9 that can cover the upper end of the body 2, and the cover (9) consists of four to six layers of thin heat insulating material (12) made of polyurethane foam between the inner shell (10) (11) phase made of the waterproof fabric as in the body (2).

One end of the bag 1 is fixed to the lower end of the body (2), the other end constitutes a handle strap or strap (13) fixed to the opposite side of the upper end of the cover (9), the handle strap or strap (13) is the body ( 2) The upper part and the cover (9) are sewn on one side to be fixed.

The bag 1 is preferably formed in a circular shape (= cylinder) as shown in the drawing, but it is obvious that the bag 1 may be variously implemented in a square or polygonal shape, etc. according to the shape of the storage container K. ) And the fastener 7 is a general technique and a detailed description thereof will be omitted.

In the figure, reference numeral 7a shows a button for releasing the lanyard 6 from the claw 7.

The present invention constituted as described above is to open the cover (9) by dissociating the coupling means (8), by pressing the button (7a) of the fastener (7) to release the fastening straps (6) inside the storage container (2) After storing the (K), pull the tightening strap 6 again to close the injection port, fix the tightening strap 6 by the tightening opening 7, cover the upper part with a cover 9, and cover the coupling means 8. The food or drink in the storage container (K) filled and kept to a certain temperature for a long time regardless of the external temperature or humidity to minimize the deterioration and temperature change of food or drink.

That is, the cover 9 by the fastening strap 6 and the coupling means 8 to tightly control the entry and exit of heat to the outside of the bag (1) by the sealing means of the dual structure to be kept warm and cold for a long time In addition, as shown in Figures 3 to 4 through the thin insulation (5) (12) 4 to 6 layers made of high-density polyurethane foam between the upper end of the waterproof fabric (3) 10 and the outer shell (4) (11). It is to maximize the waterproof, moisture proof and insulation efficiency.

Therefore, if the warm or hot food or drink is contained in the storage container (K), as well as the summer, even in winter or low temperature outside the content does not easily cool or cold, cold or frozen food in the storage container (K) If a drink is contained, the contents will not warm or melt even in winter or in the summer or high temperature outside. This is due to a double sealing means consisting of a string (6) and a cover (9). It is due to the waterproof, moisture-proof and high thermal insulation effect by the 5-ply insulating material (5) (12) made of high density polyurethane foam interposed between the outer skin (3) (10) (4) (11), It is easy to carry by the handle strap or strip 13 fixed to 1).

As described in detail above, the thermal insulation and thermal insulation bag 1 provided in the present invention is a thin heat insulating material made of high-density polyurethane foam between the inner and outer shells of the waterproof fabric (3) (10) (4) (11) ( 5) (12) Interposed between 4 and 6 layers, the sealing means is formed into a double structure of the cover 9 which is opened and closed by the fastening strap 6 and the coupling means 8 on the upper part of the body 2 to be waterproof, moistureproof and high efficiency. It is possible to obtain the heat insulation effect of the bag (1) by encouraging more tightly out of the heat in and out of the bag (1) to maximize the thermal insulation and cooling efficiency of the bag 1 is expected to have a lot of anticipated effects.
