Abstract
A blow molding device and a blow molding method are disclosed that can blow-mold a container with a handle without requiring a handle inserter that inserts a handle into a blow molding section. A blow molding method for blow-molding a container with a handle includes heating a preform (2) that is held by a heating transfer jig (370), transferring the preform from the heating transfer jig to a blow transfer jig (420), and transferring the blow transfer jig in a state in which a handle (500) is held by the blow transfer jig to be adjacent to the preform in a transfer direction.

A blow molding method for blow-molding a container with a handle that includes disposing a preform and the handle between a pair of blow cavity molds, and blow-molding the preform into the container to integrate the handle with the container, the blow molding method comprising:
- heating the preform in a state in which the preform is held by a heating transfer jig;
- and
- supplying the handle to the heating transfer jig in an empty state after completion of the heating so that the handle is held by the heating transfer jig, the heating transfer jig holding the handle being situated between two heating transfer jigs that respectively hold two preforms that are adjacent to each other in a transfer direction.
A blow molding method for blow-molding a container with a handle that includes disposing a preform and the handle between a pair of blow cavity molds, and blow-molding the preform into the container to integrate the handle with the container, the blow molding method comprising:
- heating the preform in a state in which the preform is held by a heating transfer jig;
- and
- supplying the handle to the heating transfer jig in an empty state after completion of the heating so that the handle is held by the heating transfer jig, the heating transfer jig holding the handle being situated between two heating transfer jigs that respectively hold two preforms that are adjacent to each other in a transfer direction,
- wherein the pair of blow cavity molds have n (n is a natural number) cavities for blow-molding a container with a handle in an area in which 2n or 3n cavities for blow-molding 2n or 3n containers without a handle are provided, and
- wherein n containers with a handle are blow-molded using the n cavities and n blow core molds.
A blow molding device that is configured to dispose a preform and a handle between a pair of blow cavity molds, and blow-mold the preform into a container to integrate the handle with the container, the blow molding device comprising:
- a heating section that heats the preform that is transferred while being held by a heating transfer jig;
- and
- a handle supply section that supplies the handle to the heating transfer jig in an empty state after completion of the heating by the heating section so that the handle is held by the heating transfer jig, the heating transfer jig holding the handle being situated between two heating transfer jigs that respectively hold two preforms that are adjacent to each other in a transfer direction.
A blow molding method for blow-molding a container with a handle that includes disposing a preform and the handle between a pair of blow cavity molds, and blow-molding the preform into the container to integrate the handle with the container, the blow molding method comprising:
- heating the preform in a state in which the preform is held by a heating transfer jig;
- supplying the handle to the heating transfer jig in an empty state after completion of the heating so that the handle is held by the heating transfer jig, the heating transfer jig holding the handle being situated between two heating transfer jigs that respectively hold two preforms that are adjacent to each other in a transfer direction;
- and
- transferring the preform and the handle simultaneously from the heating transfer jigs to a blow transfer jig,
- wherein the pair of blow cavity molds have n (n is a natural number) cavities for blow-molding a container with a handle in an area in which 2n or 3n cavities for blow-molding 2n or 3n containers without a handle are provided, and
- wherein n containers with a handle are blow-molded using the n cavities and n blow core molds.
A blow molding method for blow-molding a container with a handle that includes disposing a preform and the handle between a pair of blow cavity molds, and blow-molding the preform into the container to integrate the handle with the container, the blow molding method comprising:
- heating the preform in a state in which the preform is held by a heating transfer jig;
- supplying the handle to the heating transfer jig in an empty state after completion of the heating so that the handle is held by the heating transfer jig, the heating transfer jig holding the handle being situated between two heating transfer jigs that respectively hold two preforms that are adjacent to each other in a transfer direction;
- transferring the preform and the handle simultaneously from the heating transfer jigs to a blow transfer jig;
- inverting the preform and the handle before transferring the preform and the handle from the heating transfer jigs to the blow transfer jig,
- wherein the heating transfer jigs transfer the preform and the handle in an inverted state, and
- wherein the blow transfer jig transfers the preform and the handle in an upright state,
- wherein the pair of blow cavity molds have n (n is a natural number) cavities for blow-molding a container with a handle in an area in which 2n or 3n cavities for blow-molding 2n or 3n containers without a handle are provided, and
- wherein n containers with a handle are blow-molded using the n cavities and n blow core molds.
