DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1-2 and 4-5, the hot water bottle storage bag 1 according to the present invention is capable of storing the hot water bottle 3 through the entrance / exit 2 and, as shown in FIGS. 2 and 6, the tip 5 is opened and In the outer bag 7 made of, for example, cloth (made of woven fabric or knitted fabric), the base side edge (bottom side edge) 6 is formed as an arcuate edge in accordance with the arcuate shape of the hot water bottle 3 to be accommodated. 2, the inner bag 11 with the distal end 9 open and the proximal edge 10 formed as an arcuate edge in the same manner as described above is accommodated in a stacked state, and the outer bag 7 and the inner bag 11 are shown in FIG. As shown, they are formed integrally by sewing only on the tip side of both.
[0006]
The inner bag 11 is formed by using a heat insulating sheet 15 in which an aluminum film 13 is formed on one surface of a soft foamed resin sheet 12 and positioning the aluminum film 13 on the inner surface of the bag.
[0007]
The heat insulation sheet 15 is a polyethylene foam sheet (thickness of about 0.5 to 5 mm) that exhibits good heat insulation even with a thin wall and has flexibility as shown in FIG. 2 (B), for example. It is preferable to use one in which an aluminum film 13 as an aluminum vapor deposition film is formed on one surface of a soft foamed resin sheet 12. For example, when a hot water bottle 3 containing hot water of 80 ° C. to 90 ° C. is stored in the hot water bottle storage bag 1 as shown in FIG. 4, a temperature of about 37 ° C. to 40 ° C. is obtained on the bag outer surface 16. Is good. In addition, when the thickness of the said foam sheet is too thick, the heat insulation is too strong and the favorable heating effect is not acquired.
[0008]
The inner bag 11 is a base material obtained by cutting the outer U-shaped pieces 17 and 19 that substantially match the shape of the inner bag to be formed as shown in FIG. Using the sheet 22, the base sheet 22 is folded in half with the aluminum film 13 inside, and as shown in FIG. 8, the side edges 25 and 26 forming both sides of the crease 23 are respectively edge portions on the front and back sides. 25a, 25b, 26a, 26b are formed into a bag shape by sewing together. The inner bag 11 formed in this way has seam allowances 27 and 29 formed on both sides thereof bent to one side as shown in FIG. 6, and as shown in FIG. Are stored in a state of being almost in close contact with each other.
[0009]
As shown in FIGS. 2 to 3, the outer bag 7 has an end cloth portion 30 that forms the front end side thereof folded inside the bag with a width of, for example, about 35 mm. This folding is performed such that the bent edge portion 31 of the end cloth portion 30 is located farther outward than the tip 32 of the inner bag 11. The folded edge portion 33 of the end cloth portion 30 and the distal end side 35 of the inner bag 11 are sewn together with the proximal end side 36 of the end cloth portion 30. As a result, a tunnel-like string thread 37 is formed between the bent edge 31 and the tip 32 of the inner bag 11, and two endless strings 39, 40 are passed through the string thread 37, and the string 39 , 40 are pulled in the opposite direction as shown by a one-dot chain line in FIG.
[0010]
Thus, the said entrance / exit 2 is formed by sewing the front end side of the outer bag 7 and the inner bag 11. The integration of the outer bag 7 and the inner bag 11 is performed only at the front end side of both, and the outer bag 7 and the inner bag 11 are separated at the other parts, and as shown by arrows in FIG. Is relatively movable, the outer bag 7 has the flexibility of movement with respect to the inner bag 11 in which the hot water bottle 3 is accommodated.
[0011]
After the hot water bottle 3 is accommodated in the hot water bottle containing bag 1 having such a configuration, the hot water bottle type heater 41 shown in FIGS. it can.
[0012]
When the hot water bottle heater 41 is used, the soft foamed resin sheet 12 can ensure appropriate heat insulation, and the problem that the heater is too hot as in the prior art can be solved. Moreover, in order for the aluminum film 13 to exhibit a good heat reflection effect and heat conduction effect, the aluminum film 13 appropriately transfers the heat of the hot water bottle to the foamed resin sheet 12. As a result, the stored heat of the hot water bottle 3 is released little by little to the outside, and the hot water bottle heater 41 can be comfortably used.
[0013]
Moreover, the outer bag 7 and the inner bag 11 are integrated only at the front end side, and the outer bag 7 and the inner bag 11 are separated at other portions so that both can slide relative to each other. Therefore, when the foot is brought into contact with the hot water bottle containing bag 1, the outer bag 7 is relatively slid, and a soft contact feeling is thereby obtained. If the entire outer bag 7 and inner bag 11 are integrated, it is difficult to obtain a soft feeling when the feet are brought into contact with each other.
[0014]
In the present embodiment, as shown in FIGS. 1 and 5, the base end side (bottom side) of the hot water bottle storage bag 1 is formed as an arc edge in accordance with the arc shape of the hot water bottle. 3 can be accommodated stably without difficulty.
[0015]
In the present embodiment, since the aluminum film 13 is formed as an aluminum vapor deposition film, the aluminum vapor deposition film 13 (FIG. 2B) can be obtained even when the hot water bottle 3 is repeatedly put in and out of the hot water bottle containing bag 1. 4 (B)) has excellent wear resistance, the foamed resin sheet 12 can be more effectively prevented from being damaged.
