Title: Paint pail with depending skirt for label attachment

Abstract: A container is disclosed which has an injection molded annular mouth portion with detail of high definition, a generally cylindrical body portion blow molded from a parison integrally injection molded with the mouth portion, said body portion having an inside diameter slightly larger than the inside diameter of the mouth portion, and an annular reinforcing region joining the mouth portion to the body portion and forming a transitional surface therebetween, in which the detail of high definition in the mouth portion includes a depending skirt which serves as an outside wall over said reinforcing region providing a suitable label attachment area over the reinforcing region. Also disclosed are embodiments in which interior reinforcing ribs may be formed integrally with the depending skirt, or in which the bale ears are formed at the lower periphery of the depending skirt. Protrusions on the injection molded ribs or bale ears may be used to lock the skirt or bale ear into the body portion for added strength.
