る。However, in this invention, the bottom of the tip body having a thin-walled mouth portion that has been blow-molded in advance is replaced with a smooth spherical wall provided at the lower end of the side wall of the platform forming cavity that joins the composite molding cavity and the bottom of the tip. The handle is fitted into a mold provided with a handle-forming cavity that communicates with the reservoir, and the base, the rigging, and the handle extending from the joint of the bottom of the tip are press-molded together and simultaneously connected to the tip main body. It is something to do.
以下第2図乃至第5図に示す実施例によってこの発明を
更に詳細に説明する。The present invention will be explained in more detail below with reference to embodiments shown in FIGS. 2 to 5.
先ず通常の回転ブロー成形(まわし吹き成形)法によっ
てコツプ本体1を成形する。First, the tip body 1 is molded by a normal rotary blow molding method.
このコツプ本体1は肉薄の側壁2と比較的厚肉の底部3
とから成る。This tip body 1 has a thin side wall 2 and a relatively thick bottom part 3.
It consists of
このコツプ本体1を、第2図に示すように底部3を上向
きになるよう倒立させて台4にのせる。This tip body 1 is placed on a stand 4 with the bottom 3 facing upward as shown in FIG.
この時コツプ本体1は変形しない範囲でなるべく高温で
あることが好ましい。At this time, it is preferable that the temperature of the tip body 1 is as high as possible without deforming it.
一方、台4の上方に把手および合成形用の金型5を設け
る。On the other hand, a handle and a mold 5 for composite molding are provided above the stand 4.
この金型には上記コツプ本体1の側壁2の一部がすきま
をもって嵌入される側壁受入部6と、この上方に設けら
れた合成形用空洞7と、この合成形用空洞の側壁下端部
の一部を滑らかな球面状に膨出させて設けた肉溜り部7
aに連通する袋状の把手成形用空洞8とが形成されてい
る。This mold includes a side wall receiving part 6 into which a part of the side wall 2 of the tip main body 1 is fitted with a gap, a composite mold cavity 7 provided above this, and a lower end of the side wall of the composite mold cavity. Flesh pocket 7 that is partially bulged into a smooth spherical shape
A bag-shaped handle molding cavity 8 communicating with a is formed.
この金型5は分割型であり、把手成形用空洞8の中心線
を含む縦平面で分割できるようになっている。This mold 5 is a split mold and can be divided along a vertical plane including the center line of the handle molding cavity 8.
また第2図において合成形用空洞7はゆるやかな凹凸面
を有する略円柱状となっているが、この他に適宜の形状
としたり台11の外周に模様が形成されるようにしても
よい。Further, in FIG. 2, the composite molding cavity 7 has a substantially cylindrical shape with a gently uneven surface, but it may have an appropriate shape or a pattern may be formed on the outer periphery of the table 11.
上記構成の金型5を閉じた後、コツプ本体1をのせた台
4を上昇させて第2図に鎖線で示すようにコツプ本体の
底部3を合成形用空洞7内に嵌入させる。After the mold 5 having the above structure is closed, the table 4 on which the tip body 1 is placed is raised, and the bottom portion 3 of the tip body 1 is fitted into the composite molding cavity 7 as shown by the chain line in FIG.
このときコツプ本体1は缶成形用空洞7の下端の接触部
9に接触して位置ぎめされる。At this time, the tip body 1 is positioned in contact with the contact portion 9 at the lower end of the can molding cavity 7.
次に缶成形用空洞7の上端から溶融ガラスを投入し、第
3図に示すようにプランジャ10によってプレスして溶
融ガラスを缶成形用空洞7と把手成形用空洞8内に圧入
する。Next, molten glass is introduced from the upper end of the can-forming cavity 7 and pressed by a plunger 10, as shown in FIG. 3, to press the molten glass into the can-forming cavity 7 and the handle-forming cavity 8.
このとき溶融ガラスは、缶成形用空洞7から滑らかな球
面状に形成され流過抵抗の小さい肉溜り部7aを経て把
手成形用空洞8内に流入するので、低いプレス圧によっ
て把手成形用空洞8内に充満する。At this time, the molten glass flows from the can-forming cavity 7 into the handle-forming cavity 8 through the thickened part 7a, which is formed into a smooth spherical shape and has low flow resistance, so that the molten glass flows into the handle-forming cavity 8 by a low press pressure. Fill inside.
また、肉溜り部7aは前記コツプの底部に接合する缶成
形用空洞7の側壁下端部に設けられており、溶融ガラス

空洞8内へガラスが流入する。In addition, the meat pocket 7a is provided at the lower end of the side wall of the can-forming cavity 7 that joins the bottom of the tip, and since a drop in the temperature of the molten glass is prevented, the glass can be moved into the handle-forming cavity 8 more smoothly. will flow in.
この結果コツプ本体1の上方には台11と把手12が一
体に成形されると同時にこれらはコツプ本体1に一体に
接続される。As a result, the base 11 and the handle 12 are integrally formed above the tip body 1, and at the same time, these are integrally connected to the tip body 1.
次にプランジャ10を上げ、金型5を開いて第5図に示
される手付きコツプ13を取出すのである。Next, the plunger 10 is raised, the mold 5 is opened, and the hand tip 13 shown in FIG. 5 is taken out.
この手付きコツプ13は薄肉の口部14を有する。This handle tip 13 has a thin mouth portion 14.
上記実施例においては、把手成形用空洞8を袋状とし第
5図における把手12の上端部15を側壁2に接続させ

ロー成形後の冷却の遅い厚肉の底部3であるため接触部
9と確実に接触するとともに高温の溶融ガラスが流入し
ても割れ等を発生することが少なく、不良発生率が低い
という長所を有する。In the above embodiment, the handle molding cavity 8 is shaped like a bag, and the upper end 15 of the handle 12 in FIG. Since it only needs to be brought into contact with the mold 5, molding will not be hindered even if the side wall 2 is slightly deformed.Furthermore, the thick wall that cools slowly after blow molding is inserted into the platform molding cavity γ. Since the bottom part 3 is the bottom part 3, it is in reliable contact with the contact part 9, and even if high-temperature molten glass flows in, cracks are less likely to occur, and the defect rate is low.
なお把手成形用空洞8をコツプの側壁2と同形状の側壁
受入部6に連通させることにより、把手の上端部15を
側壁2に接続させることも可能である。It is also possible to connect the upper end portion 15 of the handle to the side wall 2 by communicating the handle molding cavity 8 to the side wall receiving portion 6 having the same shape as the side wall 2 of the tip.
以上説明したようにこの発明はあらかじめブロー成形し
たコツプ本体の底部に、台と把手を一体にプレス成形す
ると同時に接続するようにしたので、口部が薄肉の手付
きコツプを自動成形により大量生産することができ、業
務用等にも使用できる使用範囲の広い高品質の手付きコ
ツプを安価に製造することができる。As explained above, in this invention, the base and the handle are integrally press-molded on the bottom of the tip body which has been blow-molded in advance, and are connected at the same time. Therefore, it is possible to mass-produce a tip with a hand with a thin mouth part by automatic molding. This makes it possible to inexpensively manufacture high-quality hand-held tips that can be used for a wide range of purposes, including commercial use.
また溶融ガラスを缶成形用空洞のコツプの底部に接合す
る側壁下端部に設けた滑らかな球面状の肉溜り部を経て
把手成形用空洞内に流入させるので、プレス圧は低くて
よく、プレス成形時の割れのないとともに、コツプ本体
と把手との接合部にビリ等の欠点が発生しない。In addition, since the molten glass flows into the handle-forming cavity through a smooth spherical bulge provided at the lower end of the side wall that joins the bottom of the tip of the can-forming cavity, the press pressure can be low, and press forming There is no cracking over time, and no defects such as cracks occur at the joint between the tip body and the handle.
さらに広い面積でコツプ本体の底部と接続される台と一
体に把手を成形するので、把手は充分な強度をもってコ
ツプ本体に固着され、コツプ生産工程において把手の欠
落や破損が生じることがない。Furthermore, since the handle is molded integrally with the base which is connected to the bottom of the pot tip body over a wide area, the handle is fixed to the pot tip body with sufficient strength, and no breakage or breakage of the handle occurs in the pot tip production process.
