Description

本発明の他の目的は、リのない取手を有するプリフォーム及びその成形方法並びに取手付き容器及びその成形方法を提供することにある。 Another object of the present invention is to provide a preform and the molding method and the handled container and its molding method that has a handle with no burrs.

(取手付きプリフォームの説明)
先ず、図1(A)(B)(C)を参照して取手付きプリフォームについて説明する。取手付きプリフォーム100は大別して、プリフォーム本体110と取手部120とを有する。プリフォーム本体110は、図1()に示すように、ネック部112と、その下方に続く胴部114と、胴部114の下端を閉鎖する底部116とを有する。図1()では、底部116にはゲート痕116Aが残存しているが、これは取手付きプリフォーム100の射出成形後にカットされても良い。
(Explanation of preform with handle)
First, the preform with a handle will be described with reference to FIGS. 1 (A), (B), and (C). The preform 100 with a handle is roughly classified into a preform main body 110 and a handle portion 120. As shown in FIG. 1 (B ), the preform main body 110 has a neck portion 112, a body portion 114 that follows the neck portion 112, and a bottom portion 116 that closes the lower end of the body portion 114. In FIG. 1 ( B ), the gate mark 116A remains on the bottom 116, but this may be cut after the injection molding of the preform 100 with a handle.

取手部120は、図1(A)、(B)に示すように、ネック部112より側方に向けて水平に延びる基部122と、基部122よりさらに側方に向けて水平に延びかつ中央に中空領域123を有する中空リング部124と、基部122より中空リング部114の中空領域125を横切って形成されて、中空リング部124の自由端部124A側と基部122とを連結する連結部126とを有する。 Handle 120, Figs. 1 (A), (B), the base portion 122 extending horizontally toward the side from the neck portion 112, horizontally toward the further side from the base portion 122 extends and the center A hollow ring portion 124 having a hollow region 123, and a connecting portion 126 formed from the base portion 122 across the hollow region 125 of the hollow ring portion 114 and connecting the free end portion 124A side of the hollow ring portion 124 and the base portion 122. Has.

このような取手付きボトル130にあっては、取手部120が連結部126にて強度的補強されていることに加えて、ショートショットも防止されているため機械的強度はさらに高まっている。このため、ボトル本体132内に内容物が充填された状態で取手部120を把持して取手付きボトル130を持ち上げても、取手部120の破損を防止できる。 In such a handle bottle 130, in addition to the handle portion 120 is intensity reinforced by connecting portion 126, the mechanical strength for short shots are also prevented is increasing further. Therefore, even if the handle portion 120 is gripped and the bottle 130 with the handle is lifted with the contents filled in the bottle body 132, the handle portion 120 can be prevented from being damaged.

ブロー成形部44は、図3に示すように、割型からなるブローキャビティ型48と図示しない底型とを有する。ブローキャビティ型48には取手付きプリフォーム100のネック部112を保持するネックホルダー(図示せず)が設けられている。そして、ネックホルダーにて取手付きプリフォーム100のネック部112を保持した状態で、取手付きプリフォーム100内に高圧エアーを吹込み、延伸ロッド(図示せず)を延伸駆動することで、ブローキャビティ型48及び底型の形状に沿った取手付きボトル130を例えば一つずつ延伸ブロー成形するようになっている。 As shown in FIG. 3, the blow molding unit 44 has a blow cavity mold 48 made of a split mold and a bottom mold (not shown). The blow cavity type 48 is provided with a neck holder (not shown) for holding the neck portion 112 of the preform 100 with a handle. Then, while the neck portion 112 of the preform 100 with a handle is held by the neck holder, high-pressure air is blown into the preform 100 with a handle to stretch and drive the drawing rod (not shown) to blow a cavity. Bottles 130 with handles that follow the shapes of the mold 48 and the bottom mold are stretch-blow molded one by one, for example.

図5に示すように、射出コア押え板54とネックキャビティ型56との間には、4本の射出コア型58を取り付けた射出コア固定板60と、取手付きプリフォーム100を取り出すためのエジェクトプレート62とが取り付けられている。なお、射出コア型5は中空とされ、その内部に冷却パイプ5Aが配置されている。この冷却パイプ5Aの内外の各通路5B,5Cに冷却水が循環される。また、射出キャビティ型68の周囲にも冷却水の通路68Bが形成され、冷却水が循環されるようになっている。これら通路5B,5C,68Bに、図4の回転軸52を通して冷却水を循環させることで、取手付きプリフォーム100を冷却するようになっている。 As shown in FIG. 5, between the injection core holding plate 54 and the neck cavity type 56, an injection core fixing plate 60 to which four injection core types 58 are attached and an eject for taking out the preform 100 with a handle are taken out. A plate 62 is attached. Incidentally, the injection core mold 5 8 is hollow and the cooling pipe 5 8 A is disposed therein. The cooling pipe 5 8 each passage 5 8 inside and outside the A B, 5 cooling water to 8 C is circulated. Further, a cooling water passage 68B is also formed around the injection cavity type 68 so that the cooling water can be circulated. These passages 5 8 B, 5 8 C, the 68B, by circulating cooling water through the rotary shaft 52 in FIG. 4, so as to cool the handle with preform 100.

また、図5に示すように、射出成形部22の機台10には、1組の射出コア型5及びネックキャビティ型56に対応して射出キャビティ型68が固定配置されている。 Further, as shown in FIG. 5, the machine base 10 of the injection molding unit 22, injection cavity mold 68 is fixedly disposed so as to correspond to a set of injection core mold 5 8 and the neck cavity mold 56.

射出コア型5、ネックキャビティ型56及び射出キャビティ型68を型締めすることで、取手付きプリフォーム100の本体110を規定するプリフォーム本体成形用キャビティ70が形成される。 Injection core mold 5 8, by clamping the neck cavity mold 56 and injection cavity mold 68, preform body molding cavity 70 which defines the main body 110 of the handle with preform 100 is formed.

そして、回転盤18に設けた射出コア型58及びネックキャビティ型56と射出キャビティ型68とを、型締めし、成形樹脂材料を射出することでネック部112に取手部120を有する有底筒状の取手付きプリフォーム100が成形されることとなる。 Then, the turntable 18 the injection core mold 58 is provided in and the neck cavity mold 56, and injection cavity mold 68, and mold clamping, a bottomed cylinder having a handle portion 120 to neck portion 112 by injection molding a resin material The preform 100 with a shaped handle will be molded.

なお、ネックキャビティ型56及び射出キャビティ型の取手成形用キャビティ72と対応する位置には、それぞれ対向方向にばね82によって構成された押出しピン84が設けられ、型開時に取手部120、ネックキャビティ型56及び射出キャビティ型68から離すようになっている。 Incidentally, at a position corresponding to the neck cavity mold 56 and injection cavity mold of the handle molding cavity 72, the extrusion pin 84, which is configured in opposite directions by the spring 82 are respectively provided, the handle portion 120 at the time of mold opening, the neck cavity It is designed to be separated from the mold 56 and the injection cavity mold 68.
