ツプを成形することができるようにしてなる。(Means for Solving the Problems) This invention according to the above object involves injection molding a preform having a foot integrally at the bottom of the main body, and molding the preform into a blowing mold having a cup molding cavity and a foot accommodating portion. After moving the body into the cup molding cavity and positioning the foot part movably from the cup molding cavity to the foot housing part, the mold is clamped, and the body is stretch-blow molded into the cup. The cup with feet can also be formed by blow molding.
（実施例） 図中１は射出金型、２は吹込金型である。(Example) In the figure, 1 is an injection mold, and 2 is a blow mold.

are connected to each other. The cup molding cavity 21 also has a blowing core 24 equipped with a rod 23 that extends the main body 31 of the preform 3 in the axial direction.
is inserted.
上記射出金型１及び吹込金型２は、公知の射出
延伸吹込成形機に取付けて使用される。成形は先
ず本体３１と本体底部に一体成形された足部３２
とを有するプリフオーム３を上記射出金型１をも
つて射出成形する。 The injection mold 1 and the blow mold 2 are used by being attached to a known injection stretch blow molding machine. First, the main body 31 and the foot part 32 integrally formed on the bottom of the main body are molded.
A preform 3 having the above is injection molded using the injection mold 1 described above.
次にプリフオーム３を公知手段により上記吹込
金型２のところまで移送する。そして本体３１を

口部に上記吹込コア２４を挿入して、本体口縁を
金型と吹込コアとにより挾持固定する。 Next, the preform 3 is transferred to the blow mold 2 by known means. After positioning the main body 31 in the cup molding cavity 21 and the foot portion 32 from the cup molding cavity 21 into the foot portion accommodating portion 22, the mold is clamped, and the blowing core 24 is inserted into the opening of the main body 31. Then, the rim of the main body is clamped and fixed between the mold and the blowing core.

有する足付カツプ４が成形される。 Thereafter, the stretching rod 23 is stretched to stretch the main body 31 in the axial direction, and the blowing core 2
4. Blow air into the main body to expand it to the full extent of the cavity and form it into a cup shape. During the above-mentioned stretching, since the foot portions 32 are movably housed in the mold, they do not pose any obstacle to the stretching of the main body 31 in the axial direction, allowing the stretching of the main body 31, and allowing the stretching of the main body 31. Then, the footed cup 4 having the foot portion 32 integrally formed at the bottom of the main body 41 is molded.
この発明においてプリフオーム３の本体３１及

とする。また足部の冷却固化を目的として足部断
面を星形などに形成しもよい。 In the present invention, the shapes of the main body 31 and the foot portions 32 of the preform 3 are arbitrary within the range that allows for release from the mold. Further, the cross section of the foot portion may be formed into a star shape or the like for the purpose of cooling and solidifying the foot portion.
上記足付カツプ４の模様付は、吹込金型２のカ
