PURPOSE:To stably maintain rigid engaging assembling of a bottle body with a grip by sufficiently increasing a deformation preventive force of the grip of a support protrusion to be molded at the body in terms of an engaging functional part. CONSTITUTION:With an engaging assembling part of a grip 11 as an insert material an engaging assembling part of a bottle body 1 is stretching molded to mold a support protrusion 10 of part of the assembling part of the body 1 in a sufficient protrusion height, and hence a deformation preventive force of the protrusion 10 to an assembling beam piece 13 of the grip 11 is made strong and stable. Thus, the assembling fixture of the grip 11 to the body 1 is rigidly and stably performed and maintained. |
