Claims (9)

A method of forming a blown bottle with a handle, which is a molded article of a unitary body, by injecting pressurized fluid into a thermoplastic parison which is placed in a blow mold with a handle and heated to a temperature suitable for shaping, wherein the parison and the handle are previously precisely positioned. And are simultaneously supported into said blow mold to be blow molded. 2. A method according to claim 1, wherein the parison and the handle are located on each holder and are moved in a circle through the heating zone into the forming zone. 2. The method of claim 1, further comprising: a first step of positioning the parison on one holder, a second step of heating the parison, and the other holder on the other holder to maintain the correct position relative to the parison. And a fourth step of blow molding to join the parison and the handle, wherein the first and fourth steps are performed in a circle. 2. The method according to claim 1, wherein the parison and the handle are simultaneously molded by injection molding while maintaining a precise positional relationship in the injection molding zone, and are moved in a circle through the heating zone to the blowing zone. 2. A method according to claim 1, wherein the handle is located on a non-rotating holder while the parison is placed on a rotating material. A unit for conveying in a circle, a first holder for vertically supporting a parison attached to the conveying unit, a second holder attached to the conveying unit for supporting a handle to a predetermined position with respect to the parison, the paddle A heating unit for heating the listen, a blow mold for receiving a parison and a handle on the first and second holders, and an air blowing unit for supplying pressurized air into the parison when the parison is located in the blow mold Apparatus for forming a blown bottle with a handle, characterized in that consisting of. 7. A molding apparatus according to claim 6, wherein a plurality of sets of said first and second holders are attached to a unit for conveying by forming said circle. A transfer unit, a first injection mold disposed on the transfer unit to mold a handle, a second injection mold disposed on the transfer unit to mold a parison on both sides of the first injection mold, and heating the parison A heating unit, a blow mold for accommodating the parison and the handle, an air blowing unit for supplying pressurized air into the parison when the parison and the handle are located in the blow mold, and a removal unit for removing the blown article. And wherein they form a circle and are disposed around the transfer unit. 9. A molding apparatus according to claim 8, wherein the first and second injection molds have holder plates for supporting the parison and the handle as separable portions thereof. ※ Note: The disclosure is based on the initial application.
