PURPOSE: To continuously and easily bond and fix a label by setting the stiffness of the label being an insert material to a degree easily bent by the heat and pressure of the molten molding resin material of a cylindrical main body and bonding and fixing one end edge part of the peripheral surface label bonded and fixed to a peripheral wall part in a wound state to the other end edge part in the peripheral, direction of the label. CONSTITUTION: A label being an insert material is divided into a peripheral surface label and an end surface label and the peripheral label is arranged to the inner peripheral surface part of the molding surface on the cavity side of a cylindrical injection mold and the end surface label is arranged to an end plate part. At this time, one side edge part 11 of the peripheral surface label 10 is superposed on the other side edge part 12 thereof from the outside. When the molten molding resin material of a cylindrical main body is injected into a molding space in this state, the adjacent part of the other side end edge part 12 superposed on one side end edge part is easily bent by the action of the pressure from the molten molding resin material so as to cover the end surface of one side end edge part 11 and strongly bonded to the other side end edge part 12 by a preliminarily coated adhesive. |
