Description of the Related Art One of the heat-insulating double-walled containers made of synthetic resin that has been proposed in the past is that the thermal conductivity of air in a space layer of a double-walled container composed of an inner container made of synthetic resin and an outer container is higher than that of air. There is a gas filled with a small gas. In this heat-insulating double-walled container made of synthetic resin, a metal coating of a plating film is formed on the surface of the double wall on the space layer side in order to enhance gas barrier properties.
Polycarbonate resin is generally used for the inner and outer containers as a hot water resistant resin, but plating is not possible because the plating film cannot be directly attached to the outer surface of the inner container or the inner surface of the outer container molded with polycarbonate resin. A coating containing a suitable resin was applied to form a plating film.

ある。However, polycarbonate resin is inferior in chemical resistance to organic solvents, bleaching agents, detergents, and the like. Cracks (solvent cracks) may occur, and when the cracks occur, there arises a disadvantage that the gas barrier properties of the insulated double wall container made of synthetic resin are impaired. Also, in the subsequent step of sealing the low thermal conductivity gas into the space of the double-walled container, when sealing with a sealing plate using an adhesive, a solvent contained in the adhesive may be used in the vicinity of the sealing portion, Cracks may occur in the sealing plate. Further, even in actual use, it is sufficiently conceivable that cracks are generated by the contents of food, drinking water, bleach, various detergents and the like. In addition, since polycarbonate resin has poor gas barrier properties of the resin itself,
In order to impart gas barrier properties, it is necessary to apply a highly accurate plating film, and there is a disadvantage that the production cost increases accordingly.

A mixed resin of polycarbonate and polyester is used as the chemical resistant resin. This mixed resin preferably has a mixing weight ratio of polycarbonate and polyester of 7:
It is a blend of about three. Since this mixed resin has chemical resistance that does not change even when it comes into contact with chemicals such as an organic solvent, a bleaching agent, and a detergent, the outer surface of the inner container 3 or the outer container 2 for forming a plating film is formed. Even when an ABS resin paint for plating is applied to the inner surface of the substrate, cracks (solvent cracks) due to the solvent of the paint do not occur. Even after the container 1 is formed, even if the contents are put into the container 1 or the container 1 is washed with a detergent or the like, there is no fear that the inner surface of the inner container 3 or the outer surface of the outer container 3 is cracked. In addition, this mixed resin is hot water resistant and has several levels of gas barrier properties better than polycarbonate.
Therefore, the rate at which the low thermal conductivity gas filled in the space portion 4 passes through the vessel wall and escapes outside the container is extremely small.
Therefore, when the product life is short, it is not necessary to form a plating film on the surface facing the space 4 between the inner and outer containers 2 and 3 in order to enhance gas barrier properties. The polyester includes polyethylene terephthalate and polybutylene terephthalate.

Silver plating or the like is used, and a plating film is formed on the chemical plating by electroplating. Thereby, the radiation heat transfer of the container 1 can be suppressed, and the gas barrier properties of the inner and outer containers can be enhanced. As described above, since the mixed resin of polycarbonate and polyester has excellent gas barrier properties, partial non-adhesion of the plating film, which has been conventionally regarded as poor plating, can be tolerated to some extent, and the defective rate of plating can be reduced. . Therefore, the manufacturing cost can be reduced.

A plating film is formed only on the application surface. Since the adhesion of the plating film on the application surface of the ABS resin paint becomes good,
A paint can be applied only to the surface excluding the joint 7 of the inner container end 7 and the outer container end 6 and the opening 8 to form a dense plating film.
