かつ安価に大型のボトルを製造することができるという
利点がある。Saturation Po! ! Biaxially stretched blow-molded bottles made of ester resin have the advantage of excellent gas barrier properties and toughness, as well as the advantage of being lightweight and capable of producing large bottles at low cost.
しかしながら、このような大型のボトルに飲料等の内容
物を充填した際には、かなりの重量となり、食卓上で少
量ずつ内容物を取り出そうとする場合などに、ボトルを
持つのに不便を感じるという問題がある。However, when such a large bottle is filled with beverages or other contents, it becomes quite heavy, making it inconvenient to hold the bottle when trying to take out the contents little by little on the dining table. There's a problem.
この問題を解決するために、ボトル本体に把手を取り付
けたボトルが提案されている（実開昭６２−１５９３３
３〜５号公報）。In order to solve this problem, a bottle with a handle attached to the bottle body has been proposed (Utility Model Publication No. 62-15933

よい。The asymmetrical bottle of the present invention is usually formed by biaxial stretch blow molding, and in this molding process, by providing a convex portion corresponding to the concave portion 2.3 on the inner surface of the stretch blow mold, the convex portion corresponding to the concave portion 2.3 is formed. 3 can be formed very easily. At this time, as shown in FIGS. 1, 3, and 4, it is preferable to form the lower ends of the four parts 2.3 with an incline because stretchability is improved. The shape, depth, and length of the recesses 2.3 and the spacing between the recesses 2.3 may be appropriately selected depending on the size of the bottle, the type of contents, etc., so that the handle 4 can be easily held.
