A production device for a fuel tank, having two or more built-in components attached to an inside of a fuel tank body when the fuel tank body is formed, includes: jigs configured to have the built-in components placed thereon; and a feed robot, as a feed device, configured to feed the built-in components, along with the jigs having the built-in components placed thereon, to a position below molding dies. The feed device may feed the jig, having the built-in components placed thereon, to the position via a subsurface feed path leading to the position.

A method for producing a plastic container provided with at least one insert part by blow molding, which includes introducing a tubular preform, which is open at least at one end, into a blow molding tool; inserting the insert part into the open end of the preform together with a protective device, which prevents the insert part from adhering to the inner surface of the preform during the inserting operation; pulling out the protective device from the preform; closing the blow molding tool; and carrying out a blow molding operation. Also disclosed is an apparatus suitable for performing this method.

A transparent plastic integrally molded goblet has a cup-shaped part, a columnar first leg and a disc-shaped first base integrally molded from transparent plastics. The bottom edge of the cup-shaped part extends downwards to form the first leg. The bottom end of the first leg integrally forms the first base. The cup-shaped part has a circumferential wall which encloses the circumference of a first space. The top edge of the circumferential wall forms an annular first ring frame, and the central part of bottom edge of the first base downwards forms a first convex pin. The integral molding of transparent plastics can enhance the appearance integrity of the goblet, the manufacture of the goblet is easy and the product yield is increased.

A method of forming a tank with a stiffening assembly includes forming a fuel tank such that the tank wall carries at least a first and second insert, locating a connecting assembly within the tank interior aligned with the first and second inserts, the connecting assembly including a tubular body, a first coupler, and a second coupler, and coupling at least a portion of the first insert with the first coupler and at least a portion of the second insert with the second coupler to limit movement of the two wall portions relative to each other.
