Since the body member is shaped into the same shape as when the contents are filled, the lower end opening of the body member has substantially the same shape as the bottom member, and the lower end opening of the body member is somewhat larger than the bottom member. The bottom member can be smoothly fitted into the lower end opening of the trunk member without being set large. Therefore, unlike the conventional manufacturing method in which the lower end opening of the body member must be set to be somewhat larger than the bottom member, wrinkles and the like do not occur at the lower end of the body member. The lower end of the member and the peripheral wall of the bottom member can be cleanly heat-sealed.

A hollow member having an inner peripheral surface 31b curved along the outer peripheral surface of the inner peripheral surface 31b.
1c are formed at regular intervals in the vertical and horizontal directions, and a tapping 31d for connecting to a suction device (not shown) via a tube is formed on the outer peripheral surface 31a.

As a result, the bottom member 20 approaches the lower end opening of the trunk member 10 and, at the same time, air is supplied from the spout 13 of the trunk member 10 by an air supply device (not shown), whereby the trunk member 10 is pushed outward from the inside to the outside. , Shaping member 31
Is completely adsorbed on the inner peripheral surface 31b. At this time, since the lower end opening of the body member 10 is substantially closed by the bottom member 20, the air supplied to the body member 10 is hardly discharged to the outside from the lower end opening, and the body member 10 is The supplied air ensures the inner peripheral surface 31 of the shaping member 31.
It will be pushed to the b side.

As described above, when the bottom member 20 is fitted into the lower end opening of the trunk member 10, the shaping member 31 shapes the trunk member 10 into substantially the same shape as when the contents are filled, thereby forming the trunk. Since the lower end opening of the member 10 is expanded in a substantially circular shape similar to the outer diameter shape of the bottom member 20, the inner diameter of the lower end opening of the body member 10 is set to be slightly larger than the outer diameter of the bottom member 20. Even with this degree, the bottom member 20 can be smoothly and securely fitted into the lower end opening of the body member 10.
【0023】従って、この製造方法を採用すると、胴部

シールすることができるという効果がある。Therefore, when this manufacturing method is adopted, the inner diameter of the lower end opening of the body member 10 does not need to be set to be somewhat larger than the outer diameter of the bottom member 20.
The lower end of the body member 10 and the peripheral wall 22 of the bottom member 20 can be heat-sealed neatly without wrinkles or the like at the lower end of the zero. In particular, when the body member 10 is formed of a thin synthetic resin sheet having no stiffness, there is an effect that heat sealing can be performed neatly.

うなボトム付き袋状容器を製造することができる。Also, since the body member 10 and the bottom member 20 are heat-sealed in advance in the same state as when the contents are filled, the body member 10 and the bottom member 20 are not sealed when the contents are filled. Thus, it is possible to produce a bag-like container with a bottom that has the most beautiful shape when the contents are filled without distortion occurring in the heat-sealed portion.

ある。Further, in this manufacturing method, when the body member 10 is shaped by the shaping member 31, air is supplied from the spout 13 to the inside of the body member 10, so that the body member 10 is also expanded from the inside thereof. As a result, the outer peripheral surface of the body member 10 is fixed to the inner peripheral surface 31b of the shaping member 31.
There is an effect that it is possible to uniformly and surely adsorb.
