Claims8
An apparatus for forming a blown bottle with a handle which comprises:
- a circularly transferring unit,
- a first holder attached to said transferring unit to hold a parison vertically,
- a second holder attached to said transferring unit to hold said handle so that said handle is at a predetermined position with respect to said parison,
- a heating unit to heat said parison,
- blow mold for simultaneously receiving said parison and said handle on said first and second holders while maintaining said predetermined position of said handle with respect to said parison, and
- an air-blowing unit to supply pressurized air to said parison when it is positioned in said blow mold.
