Description

本発明は、胴部の形状が同じで、口部ないし首部形状が異なる一連のガラスびんを製造する方法に関する。   The present invention relates to a method for manufacturing a series of glass bottles having the same body shape but different mouth or neck shapes.

図８は、胴部形状が同じで、口部の径が異なる２種類のびんを製造する場合の説明図である。同図の上段は口部径が大きい場合、下段は口部径が小さい場合である。上段、下段共に仕上型２は同じもので、上段の口型１Ａと下段の口型１Ｂとは、成形面１１及びガイドリング１３の形状が異なっている。   FIG. 8 is an explanatory diagram when two types of bottles having the same body shape and different mouth diameters are manufactured. The upper part of the figure shows the case where the mouth diameter is large, and the lower part shows the case where the mouth diameter is small. The finishing mold 2 is the same for both the upper and lower stages, and the upper mouth mold 1A and the lower mouth mold 1B are different in the shapes of the molding surface 11 and the guide ring 13.

図９は、図８の仕上型成形で成形したガラスびんの側面図で、左側のガラスびん６Ａは口部径が大きく、右側のガラスびん６Ｃは口部径が小さくなっている。一点鎖線より上が口型で成形された部分、下が仕上型で成形された部分であり、仕上型で成形された部分は双方全く同じ形状である。口部径の小さなガラスびん６Ｃでは、口部の小さい径から仕上型の上端の大きい径に移行するため、口型１で成形される首部の部分にビード６３を設けていた。   FIG. 9 is a side view of a glass bottle formed by the finish molding shown in FIG. 8. The left glass bottle 6A has a large opening diameter, and the right glass bottle 6C has a small opening diameter. The portion above the alternate long and short dash line is a portion formed by a mouth mold, and the portion below is a portion formed by a finish die, and the portions formed by the finish die have the same shape. In the glass bottle 6C having a small mouth portion diameter, the bead 63 is provided in the neck portion formed by the mouth die 1 in order to shift from the small diameter of the mouth portion to the large diameter of the upper end of the finishing die.

また、下記特許文献１では、粗型又は仕上型の本体の成形面の首部を成形する部分に半ドーナツ板状の切欠部を形成すると共に、この切欠部に、内周面が首部成形面となっている半ドーナツ状の首部成形体を微動可能に取り付ける技術が開示されている。首部成形体を本体と別体とし、かつ、首部成形板が本体に対して微動可能であるので、型開きの際にガラスに加わる衝撃が緩和され、ガラスびんの首部にクラックやしわなどの欠点が発生しにくくなるという作用効果を有する。   Further, in Patent Document 1 below, a half donut plate-like notch is formed in a portion for molding the neck of the molding surface of the main body of the rough mold or the finish mold, and the inner peripheral surface of the notch is the neck molding surface. A technique for attaching a half-doughnut-shaped neck molded body that can be finely moved is disclosed. Since the neck molded body is separate from the main body and the neck molded plate can be moved finely with respect to the main body, the impact applied to the glass during mold opening is mitigated, and there are defects such as cracks and wrinkles in the neck of the glass bottle Has the effect of becoming less likely to occur.

特開２００１−３２８８２５JP 2001-328825 A

従来、胴部形状が同じで、口部の径が異なる２種類のびんを製造する場合、径の小さなびんの首部にはビードを付けなければならず、これによりびんの商品イメージが著しく異なってしまっていた。ビードを付けずに径の小さなびんを成形しなければならない場合、新たな粗型及び仕上型を容易しなければならず、コスト高となっていた。   Conventionally, when manufacturing two types of bottles with the same body shape and different mouth diameters, the neck of the small diameter bottle has to be beaded, which significantly changes the product image of the bottle. I was sorry. When a small-diameter bottle has to be formed without a bead, a new rough mold and finish mold must be facilitated, resulting in high costs.

本発明は、胴部形状が同じで、口部の径が異なる複数種類のびんを製造する場合、ビードを付けることなく、径の小さなびんを容易かつ安価に製造できるようにすることを課題とするものである。   An object of the present invention is to make it possible to easily and inexpensively manufacture a small-diameter bottle without attaching a bead when manufacturing a plurality of types of bottles having the same body shape and different mouth diameters. To do.

成形するガラスびんの首部形状に応じた首部成形面を有する複数種類の前記首部成形体を用意し、
成形するガラスびんの口部ないし首部の形状に応じて選択した口型及び前記首部成形体を取り付けた粗型及び仕上型により成形することを特徴とするガラスびんの製造方法である。 The present invention provides a plurality of types of mouth molds according to the mouth shape of the glass bottle to be molded,
A half donut plate-like neck part having a half donut shape formed at the upper end of each half, and having an inner peripheral surface serving as a neck part forming surface in the notch part. In rough and finish molds that are detachably attached,
Prepare a plurality of types of the neck molded body having a neck molding surface according to the neck shape of the glass bottle to be molded,
A glass bottle manufacturing method characterized by forming by a mouth mold selected according to a shape of a mouth part or a neck part of a glass bottle to be molded, a rough mold and a finishing mold to which the neck molded body is attached.

口部成形体で、小さな径の口部から大きな径の首部までの形状を滑らかに変化させることができるので、口部径の小さなびんにビードを設ける必要がなく、口部径の大きなびんとの商品イメージの違いを小さくすることができる。
口型と首部成形体を選択し、粗型及び仕上型の本体は共通でよいので、口部ないし首部の形状が異なる多種類のびんを安価かつ容易に製造することができる。 Since the shape from the small-diameter mouth part to the large-diameter neck part can be changed smoothly with the molded mouth part, it is not necessary to provide a bead on the small-bore bottle, and the large-bore bottle The difference in product image can be reduced.
Since the mouth mold and the neck molded body are selected and the main body of the rough mold and the finish mold may be common, various types of bottles having different shapes of the mouth or neck can be manufactured inexpensively and easily.
