はキヤビテイ形成面へ接触させておく。 The above bottle may be manufactured as follows. First, a parison 21 made of saturated polyester resin is formed in advance by injection molding, for example, and has a cylindrical shape with a bottom and an open top, and has an outward flange 5 on the outer periphery of the base of the mouth and neck. The outward flange of the parison and its upper neck part serve as the neck part of the bottle, and when forming a bottle for screwing the cap, a thread 4 is provided on the outer periphery of the neck part. A state in which the cylindrical portion lower than the outward flange of the parison is inserted into the ring portion 7 of the handle 6 previously formed, so that the lower surface of the outward flange and the upper surface of the ring portion are overlapped, and the lower end of the handle is suspended. Attach the parison and handle to the holder. Either before or after said mounting, the parison is heated to a temperature suitable for expansion. If the handle is a hindrance when heating the parison after installation, the handle can be heated while being rotated relative to the parison. It is sufficient to heat only the portion below the outward flange. However, if the handle is attached immediately after forming the parison and the parison is maintained at a temperature suitable for expansion, there is no need to heat it again.
The parison and handle are placed in the blow molding molds 22, 22 in the attached state. The parison is placed in the cavity 23 for molding the bottle body, and the handle 6 is placed in the handle fitting groove 24.
The outer surface of the second ring portion 7a at the lower end of the handle is brought into contact with the cavity forming surface.

取出す。 From the above state, blow compressed air into the parison,
During the blowing, a stretching rod (not shown) is inserted into the parison and the bottom of the barison is pushed down to stretch and expand the parison in the axial direction. As a result of the expansion, an overhanging wall portion 11 that sandwiches the ring portion 7 with the outward flange is formed, and a bite portion of the above-mentioned uneven stripes is formed.
The second ring portion 7a attached to the lower end of the handle is bitten into the outer surface of the bottle body and fixed thereto. After the bottle body is blow-molded in this way, the mold is opened and the bottle with handle is taken out.

る。 The handle 6 is preferably provided on the bottle body so that the outermost portion of the handle is located inward of, or at least on the same line as, the outer circumferential line of the body of the bottle in the plane of the bottle. This makes it easy to wrap and package the bottle, and since the handle portion does not protrude from the outer surface of the bottle body in the vertical direction, it is possible to prevent the handle from touching other objects and becoming a hindrance.

を容易かつ確実に固着させることができる。"Effects of the Invention" The present invention has the above structure, and since the bottle body is made of saturated polyester resin, harmful substances such as solvents do not ooze out during use, and no harmful gases are released when incinerated after disposal. Never occurs. In addition, since it is a large bottle with a capacity of at least 1 liter that has been biaxially stretched, the bottle has high mechanical strength due to the biaxial stretching and is lightweight, and because it has a handle, it is a large bottle. Since the handle is not integrally molded with the bottle body, but is attached with a separately molded synthetic resin handle, biaxial stretching of the bottle body does not become difficult. Since the handle is a separate member from the bottle body, there are many handles A, B,
If the handles of soybean oil bottles are colored A, the sauce is B, and the cooking oil is C, etc., it will be extremely easy to distinguish between the items stored in the bottles. There are other effects. Furthermore, the handle 6
A ring part 7 is attached to the base end of the parison, and a projecting wall part 11 is formed at the base of the neck part of the bottle body by blow molding with the ring part inserted into the parison from below. The ring part 7 is irremovably held between the outward facing flange 5 formed on the mouth and neck, and the second ring part 7a attached to the lower end of the handle 6 is attached to the outer surface of the body of the bottle body during blow molding. Since it is fitted in a biting state, the handle can be easily and reliably fixed.
