  FIG. 1 is an overall perspective view of an external appearance showing an example of a cold insulation container according to the present invention, and FIG. 2 is a cross-sectional view of a material of a bag portion used in the cold insulation container according to the present invention. The cold insulation bag 10 according to the present invention includes a handle portion 12 and a bag portion 14 for storing a load. The cold insulation bag 10 according to the present invention only needs to have at least the bag part 14, and may include the handle part 12 or the like.

  If the material of the bag portion 14 is a composite material 16, the composite material 16 is composed of a cold insulation member 18 and an outer surface member 20 as shown in FIG. 2. A cap film 24 having a large number of cap shapes is attached to one side of the first basic sheet 22 made of polyethylene, and the first basic sheet 22 made of polyethylene and polyethylene are used as the cold insulation member 18. A bubble cushioning material (first layer) 28 in which bubbles 26 obtained in a large number of sealed spaces are formed on one surface of the first basic sheet 22 with the cap film 24 to be used. In the bubble cushioning material 28, a large number of bubbles 26 have a heat insulating effect. Desirably, the cold insulation member 18 is provided with a thin aluminum layer (second layer) 30 on the first base sheet 22 side of the bubble cushioning material (first layer) 28. The aluminum layer 30 has a good light-shielding property and heat reflectivity, and is intended to improve the cold insulation effect. The aluminum layer 30 is vapor-deposited on the first base sheet 22 of the bubble cushioning material 28 or is pressed. For example, the aluminum layer 30 can be fixed to the bubble buffer material (first layer) 28. In this case, the cold insulation member 18 has a bubble cushioning material (first layer) 28 and an aluminum layer (second layer) 30 fixed thereto. When the bubble cushioning material (first layer) 28 is manufactured, an aluminum layer (second layer) 30 is deposited on the first base sheet 22 side to thereby form an aluminum layer (first layer) on the bubble cushioning material (first layer) 28. The cold insulation member 18 to which the (two layers) 30 is fixed is manufactured.

  The outer surface member 20 includes a protection member 32 and a printing layer 34 provided on one surface of the protection member 32. The printed layer 34 is applied to the cold insulation container 10, for example, a pattern or pattern such as the design 36. The protection member 32 is for protecting the printing layer 34 and the cold insulation member 18 from external friction or impact. The protective member 32 is required to have translucency and transparency so that the design of the pattern and design of the printed layer 34 can be visually recognized through the outside of the protective member 32. It is desirable to use polyethylene. When the protective member 32 is manufactured, a member obtained by simultaneously attaching the printing layer 34 to one surface of the protective member 32 is manufactured as the outer member 20.

  In the present invention, since the material of the protective member 32 to be printed is polyethylene, compared with a printing method such as silk screen printing generally used for materials such as conventional leather and cloth, gravure printing and Various printing methods such as offset printing can be applied, and elaborate photographs and other designs can be applied with good coloring. Further, for example, a polyethylene sheet material wound in a roll shape is considered as the protective member 32, and the protective member 32 is directly subjected to a rotary press to continuously print on one side of the protective member 32 (form a printing layer 34). It becomes possible. As a result, it is possible to form a large number of print layers 34 having a design such as elaborate photographs and patterns at high speed, so that low cost can be realized. Further, even when a pattern or pattern is repeatedly printed (total pattern), the joint between the pattern and the pattern is not conspicuous and can be finished beautifully.

  Next, the composite material 16 is formed using the cold insulation member 18 and the printed outer member 20. In that case, the aluminum layer 30 (the first basic sheet 22 when the aluminum layer 30 is not provided) side of the cold insulation member 18 and the printed layer 34 side of the outer member 20 are bonded and fixed by, for example, thermocompression bonding. By doing so, the composite material 16 is formed.

  The composite material 16 formed by adhering and fixing the cold and heat retaining member 18 and the outer surface member 20 becomes the material of the bag portion 14. In the bag portion 14 using the composite material 16, a protective member 32, a printing layer 34, an aluminum layer (second layer) 30, and a bubble cushioning material (first layer) 28 are sequentially arranged from the outside toward the inside. In this case, the printed layer 34 and the aluminum layer 28 can be seen through the protective member 32, but the aluminum layer 28 becomes a plain background, and the printed layer 34 can be seen in front of the plain background. That is, the printed portion 34 representing the design such as a pattern or a pattern can be seen from the outside through the protective member 32 having translucency and transparency. Since the protective member 32 is disposed on the outermost side, even if friction or the like from the outside of the bag portion 14 occurs, the peeling of the print layer 34 and the deterioration of the coloring can be prevented by the presence of the protective member 32. .

  The cold insulation member 18 according to the present invention is not limited to the above configuration. For example, instead of the cold insulation member 18 shown in FIG. 2, a cold insulation member 18A shown in FIG. 3 may be used. The cold insulation member 18A is obtained by changing the bubble cushioning material 28 used for the cold insulation member 18 to a bubble cushioning material 28A. The bubble cushioning material 28 is formed by forming a plurality of bubbles 26 that are sealed spaces with the first basic sheet 22 and the cap film 24, and the first basic sheet 22 is exposed on one side, and the other side. Indicates that the cap film 24 is exposed. The bubble cushioning material 28A is based on the bubble cushioning material 28, and the second base sheet 22A is bonded to the cap film 24 side. One surface of the bubble cushioning material 28A is the first basic sheet 22, and the other surface is the second basic sheet 22A. The cold insulation member 18A is composed of the bubble cushioning material 28A and the aluminum layer 30. In the bubble cushioning material 28A, a large number of bubbles (sealed space) 24 are formed by the cap film 24 and the first basic sheet 22, and a large number of bubbles (sealed) are formed by the cap film 24 and the second basic sheet 22A. Space) 24A is formed. 3, the aluminum layer 30 is attached to the first base sheet 22 side as in FIG. 2, but the aluminum layer 30 is not provided on the first base sheet 22 side but on the second base sheet 22 </ b> A side. It is good also as what attaches.

Next, as shown in FIG. 4, the cold insulation member 38 may be one in which two cold insulation members 18A are used and the second basic sheets 22A are bonded to each other. In this case, the aluminum layer 30 is disposed outside. When the two cold insulation members 18A or the cold insulation members 18 are bonded, the aluminum layer 30 is always disposed outside. By increasing the number of the bubble cushioning material 28 or the bubble cushioning material 28A to two, it is possible to enhance the cold insulation effect. In this case, the aluminum layer 30 becomes both outer sides, and the outer surface member 20 can be bonded and fixed to one outer aluminum layer 30 to design the outer side of the bag portion 14. On the other hand, a flat aluminum layer 30 is formed inside the bag portion 14, and the inner wall of the bag portion 14 can be flat and strong. In the cold insulation member 38 shown in FIG. 4, even if two bubble cushioning materials 28 or two bubble cushioning materials 28A are bonded, the weight is small, so that the burden on the arm when holding the cold insulation bag according to the present invention is small. That's it.

  Another example using the cold insulation member 18A will be described with reference to FIG. In the bubble cushioning material 28A, the cloth member 42 is attached to the sheet (for example, the second base sheet 22A) opposite to the one sheet (for example, the first base sheet 22) on which the aluminum layer 30 is deposited, and the outer side of the cloth member 42 is the back surface. Cover with a covering material 44. The cloth member 42 is desirably used from a nonwoven fabric, a woven fabric, and a knitted fabric. The reason why the cloth member 42 is attached to the bubble cushioning material 28 </ b> A is to maintain the sewing due to the presence of the cloth member 42 when the composite member 16 and the cold insulation member 18, 18 </ b> A are sewn. Further, the back surface covering material 44 is for preventing the cloth member 42 from fluffing due to the cloth member 42 sliding on the article placed in the bag when the cloth member 42 becomes the inner surface of the bag.

  Further, as shown in FIG. 6, the outer surface member 40 includes a plurality of outer surface members 20 (two layers in FIG. 6) composed of the protection member 32 and the print layer 34 in the same order (protection member 32, print layer 34, protection It may be bonded in the order of the member 32 and the printing layer 34. For example, a photograph is printed on the relatively outer printed layer 34, and a pattern, characters, or the like is printed on the relatively inner protective member 32. Thereby, when the outer surface member 38 is visually recognized from the outside, a plurality of print layers 34 can be combined to express a complicated expression or a deep expression.

  In addition, if a pattern or the like to be printed on each layer of the plurality of protection members 32 is devised, a 3D expression that produces a depth by a visual gimmick and an expression by a hologram are also possible.

  As the ink used for the printing layer 34, it is desirable to use a heat-resistant ink that does not cause discoloration or color development due to heat during thermocompression bonding.
