「産業上の利用分野」
本発明は、合成樹脂製ボトルの成形法に関す
る。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method of molding a synthetic resin bottle.
「従来の技術」
合成樹脂製ボトルは、通常、ブロー成形される
ことは詳述するまでもなくよく知られているが、
把手付きのボトルを成形する手段として、特開昭
57−59725号公報に示されている方法がある。"Prior Art" It is well known that synthetic resin bottles are usually blow molded, but
As a means of forming a bottle with a handle,
There is a method disclosed in Japanese Patent No. 57-59725.
この方法は、左右二分割される金型の後部寄り
上部の左右に、プレスタイプの加熱カツターを出
入自在に装備させ、該金型によるブロー成形直後
の金型内のボトルに対し、左右から溶融点以上に
加熱されたその加熱カツターを進入させることに
より、そのボトルの胴上部の加熱カツター当接部
分を該加熱カツターにて押し潰すとともに、その
圧潰密接部を窓孔に打ち抜きし、かつ、その圧潰
密接窓孔縁部を熱融着によりシールし、把手を形
成するものである。 In this method, press-type heating cutters are installed on the left and right sides of the upper part of the rear of the mold, which is divided into left and right halves, so that the bottles in the mold immediately after blow molding are melted from the left and right. By advancing the heating cutter heated above the point, the heating cutter contacts the part of the upper part of the body of the bottle and crushes it with the heating cutter, punches out the crushed part into the window hole, and The edge of the collapsed window hole is sealed by heat fusion to form a handle.
「発明が解決しようとする課題」
しかし、このようにして成形されたボトルは、
把手を把持した際、その圧潰密接窓孔縁部が指に
鋭く食い込んで痛みを感じさせるため、把持し難
いだけでなく、ボトルの胴上部が全体的に押し狭
められて、その容積が著しく減少し、しかも、そ
の圧潰密接窓孔縁部の熱融着によるシールが不完
全になり易く、液洩れ等を生ずることがある。``Problem to be solved by the invention'' However, the bottle formed in this way,
When grasping the handle, the edge of the crushed aperture digs sharply into the fingers, causing pain, which not only makes it difficult to grasp, but also compresses the entire upper body of the bottle, significantly reducing its volume. Moreover, the sealing by heat fusion at the edges of the collapsed tight window hole tends to be incomplete, which may result in liquid leakage or the like.
一方、ボトルの胴部に凹凸形状を付すことも可
能であるが、その凹凸の方向が不適合なもので
は、成形品が金型から取り出せないため、凹凸の
方向が著しく制限され、把手としての機能を十分
に発揮させることができるものを得ることは困難
である。 On the other hand, it is possible to add an uneven shape to the body of the bottle, but if the direction of the unevenness is inappropriate, the molded product will not be able to be removed from the mold, and the direction of the unevenness will be severely restricted, making it difficult to function as a handle. It is difficult to obtain something that can fully demonstrate this.
本発明は、かかる従来の問題点を解決しようと
するものである。 The present invention attempts to solve such conventional problems.

特徴とする。"Means for Solving the Problems" In order to achieve the above object, the present invention provides a pair of left and right recesses having a height matching the length of the handle in the vertical direction, in appropriate positions of a mold for blow molding a bottle. Heat the groove-forming mold at appropriate intervals to match the width of the handle.
And, after the bottle is blow-molded by the above-mentioned mold, the pair of left and right concave grooves are installed in the body of the molded bottle in the mold. A heating mold for molding is advanced into the mold, the body of the molded bottle is heated and press-molded, and a pair of appropriate grooves and a handle based on the grooves are formed in the body of the molded bottle. It is characterized by

Eliminates the occurrence of liquid leakage due to seal failure. Of course, after the press molding, the pair of left and right heating molds for forming the concave grooves are moved back to eliminate the inconvenience of cutting out the molded bottle.

る。"Effects of the Invention" According to the present invention, the handle is provided by forming a pair of grooves in the body of the bottle, so unlike the conventional case, the edge of the crushed tight window sharply digs into fingers, causing pain. There is no such problem and the bottle can be gripped comfortably, and since the concave groove can be recessed as much as necessary for the handle, the volume of the bottle does not need to be reduced more than necessary, and it can be gripped comfortably. Since there is no need to punch out a window hole in the collapsed close contact area or to seal the edge of the collapsed close contact window hole by heat fusion, the occurrence of liquid leakage due to poor sealing can be completely eliminated.
更に、左右一対の凹溝成形用加熱押型は、押圧
成形後に後退するので、成形完了ボトルの型抜き
の不都合を無くすことができ、所要の把手を不都
合なく形成することができる。 Furthermore, since the pair of left and right heating molds for molding grooves are retracted after press molding, the inconvenience of cutting out the molded bottle can be eliminated, and the desired handle can be formed without any inconvenience.
