Abstract: A cup-shaped reusable plastic container has an open end which has a sealing edge with a sealing surface, the sealing surface being configured such that the sealing surface is connectable with a first sealing foil. The container jacket has a wall thickness from 0.5 mm to 4.0 mm. The sealing edge has a sealing edge thickness which extends in the axial direction of the longitudinal axis, and the sealing edge thickness is from 0.8 mm and 4.0 mm. The sealing surface is configured such that the sealing surface can be connected to a further sealing foil after removal of the first sealing foil from the sealing surface of the sealing edge, and following cleaning of the reusable plastic container. Also, a method reprocesses a cup-shaped reusable plastic container.
