Abstract
A blow molded barrel having its peripheral top and bottom walls formed unitarily from thermoplastic synthetic resin has at least a lifting and transport ring formed at its upper edge at the junction of the top wall and the peripheral wall and welded to the barrel body. The ring has a trapezoidal head which is at least limitedly elastic and is connected to the weld flange by an intermediate region which is also at least limitedly elastic to reduce the transmission of shock and thereby improve the life of the well junction between the ring and the barrel body.
