Abstract
A mold unit to be used for a temperature adjustment step of a preform, the mold unit including a cavity mold configured to accommodate therein a bottomed preform made of resin, and an air introduction member configured to be in airtight contact with the preform and to supply air into the preform. The air introduction member has a blowing port through which the air is to be supplied to an inside of the preform and a discharge port through which the air is to be discharged to an outside of the preform.
Claims7
A mold unit to be used for a temperature adjustment step of a preform, the mold unit comprising:
- a cavity mold configured to accommodate therein a bottomed preform made of resin, and
- an air introduction member configured to be in airtight contact with the preform and to supply air into the preform,
- wherein the air introduction member has:
- a blowing port through which the air is to be supplied to an inside of the preform;
- and
- a discharge port through which the air is to be discharged to an outside of the preform.
An apparatus for manufacturing a container made of resin, the apparatus comprising at least:
- an injection molding part configured to injection mold a bottomed preform made of resin;
- a temperature adjustment part configured to adjust a temperature of the preform manufactured by the injection molding part;
- and
- a blow molding part configured to blow mold the preform whose temperature has been adjusted to manufacture the container made of resin,
- wherein the injection molding part is configured to:
- inject a resin material into a space having a shape of the preform, the space being formed by mold-clamping an injection molding mold;
- and
- cool the resin material inside the space after the injection of the resin material has been completed, and
- wherein a time during which the resin material is cooled in the space after the injection of the resin material has been completed is half or less of a time during which the resin material is injected.
