and a mold cavity m 2 corresponding to the body 21 of the container.
次にパリソン及び容器の成形手順を説明する。 Next, the procedure for forming the parison and container will be explained.
パリソンの成形
先ず第３図、第４図、第５図に示す如く、割型
５，５ａを開いた状態で可動型４を固定型３に接
近する方向に移動させる。Forming a parison First, as shown in FIGS. 3, 4, and 5, the movable mold 4 is moved in a direction approaching the fixed mold 3 with the split molds 5, 5a open.
このとき、転写フイルム６は、割型５，５ａの
内側を通つて垂下し、吸引孔５２の吸い付けによ
つて割型の型穴に密着して可動型４と一体に固定
型３の方向に接近移動する。 At this time, the transfer film 6 hangs down through the insides of the split molds 5 and 5a, and is brought into close contact with the mold holes of the split molds by the suction of the suction holes 52, and is integrated with the movable mold 4 in the direction of the fixed mold 3. move closer to.
次に第７図に示す如く割型５，５ａを閉じ、割
型５，５ａの上下縁で転写フイルム６を挟む。 Next, as shown in FIG. 7, the split molds 5, 5a are closed, and the transfer film 6 is sandwiched between the upper and lower edges of the split molds 5, 5a.
次いで固定型３の突型３１の先端から溶融した
樹脂を型内に注入する。 Next, molten resin is injected into the mold from the tip of the protruding mold 31 of the fixed mold 3.
溶融樹脂は型内に樹脂を充満する際に転写フイ
ルム６を型穴m1の内面に押圧し、このときフイ
ルム６は樹脂の熱によつて伸び、型穴m1にしわ
を生じることなく密接する。同時にパリソン１の
表面には転写フイルム６の模様が転写される。 When the molten resin fills the mold, the transfer film 6 is pressed against the inner surface of the mold cavity m 1 , and at this time, the film 6 is stretched by the heat of the resin and tightly fits into the mold cavity m 1 without causing wrinkles. do. At the same time, the pattern of the transfer film 6 is transferred onto the surface of the parison 1.
金型Ｍ１を開くと、フイルム６がパリソン１か
ら剥がれ、該フイルム６の絵模様はパリソン１に
残り、即ち、パリソン１の形成と同時に該パリソ
ン１に絵付けによる加飾が出来る。 When the mold M1 is opened, the film 6 is peeled off from the parison 1, and the picture pattern of the film 6 remains on the parison 1, that is, the parison 1 can be decorated by painting at the same time as the parison 1 is formed.
割型の吸引孔の吸い付けを止め、転写フイルム
６を一ピツチ移動させて次の絵模様６１を割型
５，５ａに対応させ、再び上記手順を繰り返すこ
とによつて絵模様を施したパリソン１を能率的に
製造出来る。 Stop the suction of the suction holes of the split molds, move the transfer film 6 one pitch so that the next pattern 61 corresponds to the split molds 5, 5a, and repeat the above steps again to create a parison with a pattern applied to it. 1 can be manufactured efficiently.
射出成型機の一次成形金型Ｍ１の型穴m1は容

型穴内の転写フイルム６は注入樹脂に押圧されて
フイルム６の伸びにより型穴内面に無理なく密着
し、従つてパリソン１の樽形胴部の周面全体に原
模様１４をむらなく転写することが出来る。 Since the mold cavity m1 of the primary mold M1 of the injection molding machine is barrel-shaped with a smaller curvature than the spherical surface of the container 2, the transfer film 6 in the mold cavity is pressed by the injected resin and the film 6 stretches, causing the mold cavity to collapse. It adheres easily to the inner surface, and therefore the original pattern 14 can be evenly transferred to the entire circumferential surface of the barrel-shaped body of the parison 1.
容器の製造
上記のパリソン１を第９図に示すブロー成型機
の二次成形金型Ｍ２の保持部９１に、パリソン１
の口部１２を保持せしめてセツトする。Manufacture of Container The above parison 1 is placed in the holding part 91 of the secondary mold M2 of the blow molding machine shown in FIG.
Hold the mouth part 12 of the button to set it.
パリソン１を加熱すると共に口部１２から圧力
空気を吹き込んでパリソン１を膨らませる。 The parison 1 is heated and compressed air is blown from the mouth part 12 to inflate the parison 1.
樽状のパリソン１は球面状の型穴m2に沿つて
膨らんで球面状の胴部２１が形成される。 The barrel-shaped parison 1 is inflated along the spherical mold cavity m2 to form a spherical body 21.
パリソン１は樽状であるからこれを球状に膨ら
ませるのに無理が掛からないで、均一な肉厚を形
成しやすく、転写模様はくずれにくい。 Since the parison 1 is barrel-shaped, it does not take much effort to inflate it into a spherical shape, it is easy to form a uniform thickness, and the transferred pattern is difficult to collapse.
パリソン１の樽状胴部１１が球状に膨れる際、
該胴部１１に施された原模様１４もパリソン１の
