Abstract

A method of manufacturing a container by liquid blow molding includes: a preform placement step of placing a preform in a mold; a liquid blow molding step of supplying a pressurized liquid to inside of the preform placed in the mold, and molding the preform into a container body containing the liquid; a grasp and conveyance step of grasping the container body by a grasping device at a mold opening position of the mold, and conveying the container body grasped by the grasping device to a cup capable of containing a bottom part of the container body to hold the container body; and a cup conveyance step of conveying the cup holding the container body to a capping position.

Claims

1. A method of manufacturing a container by liquid blow molding, the method comprising:

a preform placement step of placing a preform in a mold;

a liquid blow molding step of supplying a pressurized liquid to inside of the preform placed in the mold, and molding the preform into a container body containing the liquid;

a grasp and conveyance step of grasping the container body by a grasping device at a mold opening position of the mold, and conveying the container body grasped by the grasping device to a cup capable of containing a bottom part of the container body to hold the container body; and

a cup conveyance step of conveying the cup holding the container body to a capping position.

2. The method of manufacturing a container according to claim 1,

wherein in the grasp and conveyance step, the container body is conveyed in a direction parallel to a conveyance direction of the preform in the preform placement step.

3. The method of manufacturing a container according to claim 1,

wherein in the grasp and conveyance step, the container body is conveyed in a direction orthogonal to a conveyance direction of the preform in the preform placement step.

4. The method of manufacturing a container according to claim 3,

wherein when opening the mold, the mold is rotated about a rotating axis located below the mold, and displaced.
