Abstract: The invention provides a synthetic resin container with a plurality of handgrips on its top face and a manufacturing method for such a container. The plurality of handgrips, as well as an opening, are molded in advance as insertion components. After heating the fusion portions of the insertion components, the insertion components are disposed parallel to the direction in which a parison is to be placed. Thereafter, a parison is placed into dies, and the dies are clamped. Air is blown into the parison through the opening to fuse the parison and the insertion components.

Abstract: A molding machine for molding a hollow article which has at least two laminated layers. The molding machine comprises: a pair of molds 1, 2 capable of opening and closing; a core pin 3 which is disposed between the molds 1, 2 and which allows a bottom layer material 51 to fit on a peripheral surface of the core pin 3; a parison transfer device 4 which supplies a parison 42, as a top layer material, between the bottom layer material 51 and the molds 1, 2; and a pair of slide members 13 disposed in at least one of the molds 1, 2 and movable to and away from the core pin 3. The molds 1, 2, the slide members 13 and the core pin 3 are arranged to define a space which corresponds to the hollow article, when the molds are closed.

Abstract: A blow molded article comprises a hollow body having a substantially enclosed hollow space therein, the hollow space accommodating a reinforcement for structurally reinforcing a strength of the blow molded article, with the reinforcement being tightly attached and fixed to at least a part of an internal wall defining the hollow space. A molding machine for this blow molded article comprises a pair of mold halves which can freely move to and away from each other in horizontal directions, and a parison feeder for supplying a parison downwardly between the mold halves. The parison feeder is arranged to supply a bottomless parison. Below the mold halves, the molding machine is provided with a support device which holds a reinforcement such that the reinforcement is positioned inside a hollow space in the blow molded article, and also provided with elevating means for freely raising and lowering the support device.
