意が必要であり、さらには、容器内に重いものを入れる
には不適当であった。[Problems to be Solved by the Invention] However, in the bottle with a handle manufactured by the above-described conventional technique, the fitting between the molded bottle and the handle may be insufficient, and the handle may be pulled hard. If a liquid or the like is filled to fill the bottle, the handle may be detached from the bottle. For this reason, care must be taken in handling the bottle with a handle, and furthermore, it is unsuitable for putting a heavy thing in a container.
そこで、本発明の目的は、ボトルと把手とを強く嵌合
することができる把手付きボトルの製造方法を提供する
ことにある。Therefore, an object of the present invention is to provide a method for manufacturing a bottle with a handle, which can strongly fit the bottle and the handle.

力流体の流入により、把手体へ向かって膨脹する。[Operation] In the present invention, when the bottle and the handle are integrally formed, the handle moves in the direction opposite to the expansion direction of the personal computer, that is, toward the personal computer. On the other hand, the parison expands toward the handle by the inflow of the pressure fluid.
このように、パリソンは把手体方向に向い、把手体は
パリソン方向に向かうことによって、ボトルを形成する
合成樹脂が把手体の接合部に周り込むことができ、把手
体とボトルとをしっかりと嵌合することができる。As described above, the parison faces in the direction of the handle body, and the handle body faces in the direction of the parison, so that the synthetic resin forming the bottle can wrap around the joint portion of the handle body, and the handle body and the bottle are firmly fitted. Can be combined.
［実施例］ 以下、本発明の実施例を説明するが、本発明はこれに

る。The cylinder 7 moves the handle 4 in the direction opposite to the expansion direction of the personal computer 3 as indicated by the arrow 8 from immediately before to immediately after the parison 3 becomes the desired bottle shape, so that the handle 5 is joined to the bottle. The resin that constitutes the bottle goes around the portion, and the handle 4 and the bottle are fitted.
この時、把手体４の移動速度は、パリソン３の膨脹速
度と、ほぼ同速度であることが好ましい。At this time, it is preferable that the moving speed of the handle 4 is substantially the same as the expansion speed of the parison 3.
また、シリンダー７によって把手体４がボトルに押し
込まれる距離Ｘ、および、把手体の幅Ａの間には、 の関係にあることが好ましい。In addition, between the distance X at which the handle 4 is pushed into the bottle by the cylinder 7 and the width A of the handle, It is preferable that the following relationship is satisfied.
