Abstract

PURPOSE:To contrive to reduce the number of man-hour for manufacturing and to lighten the vessel body by a method wherein a hollow synthetic resin vessel is formed by directly blow-molding to the inner space of a hollow heat insulating outer shell, the outer periphery of which is restrained. CONSTITUTION:In order to manufacture the heat insulating tank 1 having the heat insulating outer shell 3 made integrally with the hollow vessel 2 on the outside of the hollow vessel 2, firstly only the outer shell 3 is dividedly formed by the conventional forming method so as to bring the profile of inner space S to the predetermined vessel form. Secondly, the formed outer shell 3 is housed in a metal mold (not shown) for blow molding and plastic resin is blown directly into the inner space S of the outer shell 3 in order to form the hollow vessel 2. Owing to the method as described above, the vessel 2 and the outer shell 3 can be closely attached with each other, resulting in enabling to make the thickness of the vessel 2 itself thinner and as well as simplifying the manufacture of the vessel body.

体的に説明する。 本発明の適用ｔこよって形成される保温タンクThe present invention relates to a method of manufacturing a heat insulating container body, such as a collector tank for a solar water heater, which is provided with a heat insulating layer as an outer shell. For example, the collector tank described above has conventionally
It is manufactured by wrapping the outer circumference of the tank body, which is molded from resin, in a styrofoam jacket formed in segments, and tightening the outer circumference of the jacket with a fastening band. However, in this method, since the tank body and jacket are handled individually, it is necessary for the tank body to have sufficient strength independently, and there remains a problem in terms of weight. Also,
The production itself requires steps such as attaching a jacket and a fastening band, and the disadvantage is that the conut is expensive due to the large number of steps. SUMMARY OF THE INVENTION An object of the present invention is to provide a method of manufacturing a heat-retaining container body that can easily solve the above-mentioned conventional problems. Next, the structure of the present invention will be specifically explained based on an embodiment shown in FIG. Application of the present invention Thermal tank formed thereby

The features of the hollow container C21 and the heat-insulating outer shell (3) are that they are in close contact with each other, and their tissue surfaces are in close contact with each other in a nearly bonding relationship. , the necessary strength as a whole is provided by both the hollow container (2) and the heat-insulating outer shell (3). That is,
The thermal tank [1] itself is sufficiently lightweight and has the necessary strength. The thermal tank (1) having such features is manufactured in the following manner. That is, first, only the heat-insulating outer shell (3) is formed using a conventional molding method. The heat retaining outer shell (3) is divided into parts depending on the form of the heat retaining tank [1]. In the illustrated example, a hollow heat-insulating outer shell (3 ) is obtained. The heat retaining outer shell (3) having this twisted configuration is placed in a blow molding mold (not shown) as it is, and the outer periphery of the heat retaining outer shell (3) is placed in a restrained state. Then, a hollow container (2) made of plastic resin is directly formed by blow molding the inner space (St) inside the heat-insulating outer shell (3).In other words, the hollow container (2) is (3
) The inner space (formed as a container defined by the profile of the inner space (81) using Sl as a mold, and the heat-insulating outer shell (3)
The outer surface of the material is in close contact with the inner surface of the material. In addition, if the surface of the inner space (81) of the heat-insulating outer shell (3) is made with small irregularities, the bonding relationship between the hollow container (21) and the heat-insulating outer shell (3) will be improved, which will improve the overall strength. As is clear from the above description of the embodiments, the present invention involves forming a synthetic resin hollow container directly in the inner space of a heat-insulating outer shell, which serves as a structure for heat-insulating, by blow molding. Since this is a method for manufacturing a heat insulating container body, a heat insulating container body with a heat insulating shell and a foot made of heat insulating material can be easily and integrally formed with a small number of man-hours. Since it is possible to form an extremely close relationship and the wall thickness of the hollow container itself can be made thin, a lightweight heat-insulating container body can be easily manufactured.
