Abstract
A method of making a bottle with a handle, wherein a synthetic-resin parison is disposed in half-cylindrical molds with a handle body, which is blow-molded and at the same time integrated with the handle body, characterized in that the parison is disposed between the opened molds; the handle body is tacked to a face of matching faces of the half-cylindrical molds; the molds are closed; and the blow-molding is performed.
Claims2
A method of making a bottle with a handle comprising the steps of:
- disposing a synthetic resin parison between opened half-cylindrical molds;
- moving an attaching head having at least one handle body detachably attached thereto in a first direction from an original position to a position between said parison and one of said half-cylindrical molds;
- moving said attaching head in a second direction toward said one half-cylindrical mold so as to position said at least one handle body in at least one handle fitting groove having a shape which approximates an outline shape of the handle body and is provided on the one half-cylindrical mold, said at least one handle fitting groove comprising suction means through which air is blown;
- tacking said at least one handle body to said at least one handle fitting groove on said one half-cylindrical mold;
- retracting said attaching head from said one half-cylindrical mold by removing said attaching head from between said parison and said one half-cylindrical mold so that attaching head is retracted to said original position;
- sucking air through said suction hole so as to secure said at least one handle body to the at least one handle fitting groove on said one half-cylindrical mold;
- closing said opened half-cylindrical molds after said retracting step;
- and
- blow molding by blowing pressurized air into said parison so as to integrate said parison with at least one handle body.
