Description of the Related Art Conventionally, as a method of manufacturing a heat-insulating double-walled container made of synthetic resin of this kind, one is to use a resin having a high gas barrier property and to form a double-walled container by blow molding with a gas having low thermal conductivity There is a method of sealing low thermal conductivity gas in a double wall container. In this method, only the resin has the gas barrier property, and it is difficult to form the radiation preventing material in the heat insulating space. As another manufacturing method, the inner and outer containers are separately molded by injection molding, and then each opening is joined with an adhesive or the like to form a double-walled container, and the air between the inner and outer containers is made into a low thermal conductivity gas. There is a way to replace it. In the inner container and the outer container formed by this method, it is possible to form a radiation preventing material consisting of plating or a metal foil on the outer surface of the inner container or the inner surface of the outer container, and after forming these radiation preventing materials, the inner container is It is housed in an outer container and connected at each opening to form a space, and from an opening formed in either the inner or outer container,
After the space was evacuated, a low thermal conductivity gas was sealed in and sealed with a sealing plate.

合がある。Generally, a high gas barrier resin used for blow molding has a low gas barrier property under high humidity. Also, at high temperatures, the strength tends to be insufficient. Further, in the double-walled container formed by the blow molding method, it is extremely difficult to form a metal foil or plating on the wall surface facing the heat insulating layer in order to reduce the radiation heat transfer. When forming the inner container and the outer container by injection molding, after forming the double-walled container by joining the inner and outer containers, after exhausting the space portion from the opening formed in any of the inner and outer containers, It is necessary to supply low thermal conductivity gas and seal the openings to manufacture an adiabatic double-walled container, which has the disadvantage of increasing the number of manufacturing steps and increasing the manufacturing cost. Further, joining with an adhesive has the disadvantages that the airtightness after encapsulating a gas with low thermal conductivity is unreliable and weak in strength.

The upper wall member 31 and the lower wall member 32 are injection-molded with a mixed resin in which a polycarbonate resin and a polyester resin are mixed at a mixing weight ratio of about 7: 3, and the inner surface of the upper wall member 31 and the outer surface of the lower wall member 32 are chemically plated. After forming a Ni underlayer by electroplating, Cu plating having a thickness of about 10 μm was formed by electroplating. The upper wall member 31 had an end outer diameter of 130 mm and a height of 23 mm, and the lower wall member 32 had an end outer diameter of 130 mm and a height of 20 mm. Three protrusions having a protrusion height of 0.5 mm were formed on the end portion of the upper wall member 31 at equal intervals. The upper wall member 31 and the lower wall member 32 are designed so that the distance between the upper and lower wall members after welding their ends is 3 to 5 mm.

得ることができる。As described above, according to the method for manufacturing a heat insulating double-walled container made of synthetic resin of the present invention, the outer container is placed in an airtight space with the inner container housed therein, and then the space is closed. After exhausting, the space is filled with the low thermal conductivity gas,
After that, since the ends of the inner and outer containers are heat-welded to manufacture the heat-insulating double-walled container made of synthetic resin, it is not necessary to form an exhaust hole in any of the inner and outer containers. Further, the method for manufacturing a synthetic resin heat insulating double-walled lid of the present invention is arranged in an airtight space with the upper wall material end portion and the lower wall material end portion in contact with each other, and then after exhausting the space. , The space is filled with the low thermal conductivity gas, and then the ends of the upper and lower wall members are heat-welded to manufacture a heat insulating double wall lid made of synthetic resin, so that an exhaust hole is formed in either of the upper and lower wall members. You don't have to. Therefore, a heat-insulating double-walled container made of synthetic resin or an upper and lower wall material in which an inner container and an outer container that do not form an exhaust hole are used, or an upper wall material and a lower wall material are used, and low thermal conductivity gas is sealed between the inner and outer containers. It is possible to manufacture a synthetic resin insulated double-walled lid with a low thermal conductivity gas enclosed in a small number of steps, reducing the manufacturing cost of synthetic resin insulated double-walled containers and synthetic resin insulated double-walled lids. It can be reduced. Further, since the exhaust hole is not formed, the container and the lid having a high degree of freedom in design can be obtained accordingly. Also, the inner and outer containers, or the upper and lower wall materials are housed in the airtight space between the lower jig and the upper jig,
Since the low thermal conductivity gas is sealed in the space after exhausting the space, it is possible to reliably fill the low thermal conductivity gas without the inclusion of air or the like. Moreover, it is easy to collect and utilize the excess gas, and it is possible to eliminate waste of the low thermal conductivity gas. In addition, the inner and outer containers and the upper and lower wall materials are housed between the lower jig and the upper jig, and the end portions of the inner and outer containers and the upper and lower wall materials are heated and welded by friction, thereby the end surface of the inner and outer containers and the upper and lower wall materials Synthetic resin double-walled container and synthetic resin double-walled container that can be joined by welding and have high airtightness at the inner and outer container ends and upper and lower wall material ends and high adhesion strength between the inner and outer containers The lid can be obtained.
