Abstract
A container for accommodating high-viscosity materials, such as liquid concrete. The container has at least one bearing sleeve, which extends through a wall opening and is fastened in the container wall in a liquid-tight manner. A shaft extends through the bearing sleeve in such a way that an annular gap is left open. A shaft seal, which bridges the annular gap and is made of elastomeric material, is located at the container-interior end of the bearing sleeve. A lubricant is applied to the annular gap from the container exterior. The invention is characterized in that the shaft seal has, on the side thereof radially facing the shaft, a conveying thread that supports the conveying of the lubricant in the direction of the container interior, which conveying thread advantageously communicates with the container interior via a check valve open to the container interior.
