Abstract: A transport and storage container for liquids has an inner plastic container having an upper bottom with a fill socket, two sidewalls, a front wall with an outlet socket at the lower edge, a back wall, and a lower drainage bottom slanted toward the outlet socket. A pallet-shaped underframe has a support bottom for receiving the lower bottom of the inner container. The front wall of the inner container has a dome-shaped bulge where the outlet socket is arranged. Two bottom portions are arranged on opposed sides of the bulge and ascend from the lower bottom toward the front wall and the corner areas adjoining the front wall or toward the front wall and the sidewalls and the corner areas adjoining the front wall and the sidewalls. They form drainage surfaces for residual liquid to be drained from the forward bottom area into the outlet socket when removing residual liquid.

A parallelepipedal or cubic inner container of plastic material with a closeable fill and outlet opening or a closeable fill and removal opening is provided. A metal cage rests against the inner container and is formed of crossing horizontal and vertical cage rods of metal. The flexible inner container has an inner envelope of a plastic foil and an outer envelope of a woven material. The inner container is fastened to at least one of an upper frame of the metal cage and a protective cover of the metal cage. The inner envelope is positioned in the outer envelope of the inner container.

Abstract: In a method for reconditioning a returnable barrel of sheet metal, that is used initially as a bung barrel having a barrel wall and a top cover with a fill and discharge bung and fixedly connected to the barrel wall, and is to be reused as a lid barrel with a bung lid or bung-free lid connected to an outwardly rolled opening rim of the barrel wall via a clamping ring closure after removal of the top cover, wherein the barrel wall has an upper portion forming a barrel neck recessed or tapered relative to the outwardly rolled opening rim of the barrel wall, wherein the top cover of the initial bung barrel has a rolled outer rim placed on the outwardly rolled opening rim of the barrel wall and connected to the outwardly rolled opening rim by lock-seaming and welding, the top cover of the bung barrel is circularly cut concentrically to a longitudinal center axis of the barrel at a transition between a plate of the top cover and an upwardly extending inner rim of the top cover to separate the plate of the top cove

Abstract: A press-fitting connector for plastic composite pipes, comprised of an inner plastic layer, an outer plastic layer, and a middle metal layer, has a support member receiving the end of a plastic composite pipe. The support member has an outer collar having a first end face facing the plastic composite pipe and a second end face facing away from the plastic composite pipe. An insulating plastic ring is positioned at the first end face. A press-fit sleeve secures the pipe end on the support member. The outer collar has two diametrically opposed cutouts. The insulating plastic ring is a curved spring washer with two convexly curved and two concavely curved portions, wherein the convexly curved portions have monolithic, axis-parallel tongues engaging the cutouts of the circumferential rib. The axis-parallel tongues in the end position of the plastic composite pipe project partially from the cutouts past the second end face of the outer collar.
