Provided is a resin container for a water server, the container including an upper surface portion where a liquid inlet and outlet portion is formed, a side surface portion connected to the upper surface portion, and a bottom surface portion disposed on a side opposite to the upper surface portion and connected to the side surface portion. A round corner surface portion is formed to the side surface portion such that the container has a polygonal shape with round corners when the container is viewed from an upper surface portion side. A wall thickness of a shoulder portion of the upper surface portion which is defined between the round corner surface portion of the side surface portion and the inlet and outlet portion is larger than a wall thickness of a portion of the upper surface portion which is adjacent to the shoulder portion.

Resin container

Provided is a method for manufacturing a containermade of resin, the method including an injection molding step S, a temperature adjustment step S, and a blow molding step S. In the temperature adjustment step S, a preformis accommodated in a cavity mold, an air introduction memberis brought into airtight contact with the preform, the air is supplied from a blowing port of the air introduction memberinto the preform, and the air is discharged from a discharge port of the air introduction memberto an outside of the preform, so that the preformis in close contact with an inner wall of the cavity moldand is cooled.

Method for producing resin vessel made of resin, mould unit and moulding apparatus

A manufacturing device of the present invention includes an intermediate molded body mold having a first accommodating space capable of accommodating a plurality of preforms, each preform having a mouth portion and a trunk portion; an intermediate molded body blowing unit configured to blow gas into the plurality of preforms arranged in the first accommodating space to inflate the plurality of preforms, thereby manufacturing an intermediate molded body having a connection portion formed by the trunk portions of the plurality of preforms welded to each other; a final molded body mold having a second accommodating space larger than the first accommodating space; and a final molded body blowing unit configured to blow gas into the intermediate molded body arranged in the second accommodating space to inflate the intermediate molded body, thereby forming an exterior shape of a multiple-chamber container.

Manufacturing device for multiple-chamber container and method therefor

A blow mold unit including: a blow mold including first and second blow cavity split molds and a plurality of raised bottom molds; first and second pressure receiving members; first and second fixing plates to which the first and second blow cavity split molds and the first and second pressure receiving members are respectively fixed; a third fixing plate interposed between the first and second fixing plates and to which the raised bottom molds are fixed at a first surface thereof; a pressure receiving rod extending down from a second surface; and a placement portion fixed to at least one of the first and second fixing plates and placing the third fixing plate thereon when the first and second blow cavity split molds are closed. The pressure receiving rod includes a first engaging portion engageable with a second engaging portion in a vertical direction.

Blow mold unit, blow molding machine and method for replacing blow mold unit

Embodiments include a blow molding machine, a method for replacing a blow mold unit, and a mold unit including a blow mold including first and second blow cavity split molds and a plurality of raised bottom molds; first and second pressure receiving plates; first and second fixing plates to which the first and second blow cavity split molds and the first and second pressure receiving plates are respectively fixed; a third fixing plate interposed between the first and second fixing plates and to which the raised bottom molds are fixed at a first surface thereof; a pressure receiving rod hanging down from a second surface and including an engaged portion engageable with the engaging portion; and a placement portion fixed to at least one of the first and second fixing plates and placing the third fixing plate thereon when the first and second blow cavity split molds are closed.
