ンク本体＝は後述するプルー成廖にて成形されている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a plastic container by forming a protruding body having an opening. However, various problems arise when integrally molding a glass Sat plastic plate with a protruding body having openings such as an injection part and a pouring part. When forming a protrusion on a part other than the parting twin of the carved metal frame,
Due to the blow ratio, the wall thickness of the protruding body is extremely thin, and due to the molding die and moldability, the shape of the protruding body is limited to avoid undercuts. On the other hand, when a protrusion is formed on a parting line, the position where the protrusion is formed is restricted, leaving parting line marks on the ejected protrusion, resulting in poor appearance and dimensional accuracy. Therefore, the present inventor considered a method of molding the container body and the protruding body separately and then joining them together, but various problems arose. In other words, the method of applying adhesive and joining does not provide a satisfactory joining strength, and the method of joining using a spin-kwelder binder does not allow accurate positioning of the protrusion, etc. A problem occurred and a satisfactory product could not be obtained.The present invention solves the above-mentioned problems.It is an object of the present invention to obtain a plastic container in which a protruding body having a desired wall thickness and shape is accurately and reliably joined. Below, the present invention will be explained based on an example of a method for manufacturing an automobile window washer liquid storage tank. In FIG. 1, 1 indicates an automobile window washer obtained by the manufacturing method of the present invention. The liquid storage tank, ToJl, and the tank body are molded using a pull molding process, which will be described later.

こともできる。Next, we will explain a method for manufacturing a wind washer fluid storage tank for a motor vehicle as shown in FIG. The mixture is melt-kneaded and extruded from the extrusion head 10 as Sybaris/U. Next, the split-type mold U having a cavity U inside is closed to hold the parison 11, and compressed air at a pressure of 3 to 7 (-) is blown into the parison 1 through the blow nozzle 14.
The parison U is blown into a shape that follows the cavity 12.After cooling, the molded product is taken out and the excess paris is removed.The bracket 3.4 is integrally formed with a nine-average wall thickness of approximately 3.
- Obtain the tank body 2. Next, a method of joining the protruding body made of the injection part 7 of polyethylene molded separately from the tank body 2 by injection molding or the like will be explained. As shown in Fig. 4 (■), the wall 2b of the tank body 2 corresponding to the opening 7a of the injection part 7 is partially cut and removed to form an opening 21 with an inner diameter of 4 m. )K Cut as shown
By providing 6 removal walls 2b with 99 recesses, the formation position and shape of the injection portion 1 can be set accurately. Then, as shown in Fig. 4 (2), the tank body 2 and the injection s7 are kept at a constant interval, and an electric heating element made of a brass plate or an electric heating element 1s with a built-in Niku PM wire etc. is inserted into the interval. Then, by heating the electric heating body with electricity, the joint l1sJL located on the outer surface of the tank body SO@ and the joint surface 8b located on the end face of the 7 flange 9 of the injection part 7 are heated for 3 to 1 seconds, and the parts are in a molten state. After reaching (zmo-zs・℃), remove the electric heating element Is and press the joint surface 8a II l) between the tank body 3 and the injection part 7 with the pressure of one vtB-K unit, and the molten part will solidify. yo] Tank body 2
and injection part 7 are joined to joint part $, - mouth part 2m, 7m
By forming the injection part 7 having the following characteristics, an automotive windshield washer liquid storage tank 1 is obtained. In addition, the tank body zK
It is also possible to join the injection part 7 and remove the tank body-shaped part 1izb corresponding to the opening part of the injection part 70 to form the opening part 2at. It is also possible to join by hot air welding, which is different from the hot plate welding described in the above example. In the case of polyolefin containers, the hot air temperature is 15C-100℃, the heating time is * ~ 30 sc, and the air volume is O, B ~ S L
It is preferable to conduct the bonding in the range of 10f@mO because the bonding condition will be good. 1 In addition, if the method uses hot air for heating, even if the joint surface 8a, l1l) between the tank body and the injection part 7 is configured in a stepped or curved shape rather than in the same shape, it will not affect the quality of the product. In addition, in the above embodiment, the beam body 2 and the injection part 7t are made of polyethylene, and 9 is made of thermoplastic plastic such as polypyrene or polyethylene. It is also possible to perform the process by changing the molding conditions and bonding conditions as appropriate.
上記実施例において、タンク本体２をプロー成形した後
、タンク本体２と注入部１０Ｈ合面ｓａ。In the above embodiment, after the tank body 2 is blow-molded, the tank body 2 and the injection part 10H are joined at the joint surface sa.

ことなく、所望の肉厚。Since Ib is melted with a hot plate or hot jLK and welded and joined, the protruding body does not become extremely thin, unlike the method of integrally molding the main body and injection part with blow molding. It is possible to freely form the undercut shape (To'), and there is no restriction on the parting line, and the desired thickness can be achieved.

ImK and can be efficiently linked. In addition, unlike the method of joining the tank body 2 and the injection part 7 with adhesive or spin welding, there is no risk of the window washer fluid leaking from the joint surface or peeling between the joints, and the shape is circular. Even if the injection part 7 is other than the above, it can be accurately positioned and firmly joined. In addition, injection part 7
By forming a 75-inch angle 9 on the surface, it is possible to increase the bonding area and improve the welding strength.

By using the method of manufacturing a plastic container joined by hot plate welding, it is possible to obtain a plastic container formed by accurately and reliably joining protrusions having a desired wall thickness, large thickness, and shape.
