The invention relates to a combination packaging container (2, 2′) comprising a beaker-shaped inner container (3) with a container jacket (17), a base (18) and a flange (20) projecting out from the container jacket (17) in the region of its open end (19), as well as a sleeve-shaped outer part (4) surrounding the inner container (3) at its container jacket (17) with end regions (11, 12) spaced apart from one another in the direction of a longitudinal axis (9). The inner container (3) is laid against and molded onto an internal face (10) of the sleeve-shaped outer part (4). The sleeve-shaped outer part (4) is of a single-layered design between its end regions (11, 12) spaced apart from one another in the direction of the longitudinal axis (9). An end face (29) of the outer part (4) lying opposite the flange (20) constitutes a standing surface for the combination packaging container (2, 2′). |

1. Method of producing a combination packaging container, whereby a sleeve-shaped outer part is placed in a deep-drawing mold before deep drawing a beaker-shaped inner container from a sheet of a plastic material, after which the beaker-shaped inner container with a container jacket, a base and a flange projecting out from the container jacket in the region of an open end of the beaker-shaped inner container is molded by a deep drawing process, during which the inner container is applied to an internal face of the sleeve-shaped outer part to form the combination packaging container, and co-operating supporting means to enable several combination packaging containers of the same type to be stacked are formed on the combination packaging container, and an end face of the outer part facing the flange is disposed immediately adjacent to a bottom face of the flange facing the base of the inner container or is applied against the bottom face of the flange, wherein the sleeve-shaped outer part is placed in the deep-drawing mold as a component extending in a straight line between end regions of the sleeve-shaped outer part spaced apart from one another in a direction of a longitudinal axis, and the inner container is applied against the sleeve-shaped outer part as the inner container is molded, and the inner container and the sleeve-shaped outer part are forced against a mold wall of the deep-drawing mold, and a pinched region projecting in a radial direction towards the longitudinal axis is formed in the container jacket in a base region of the container jacket and of the sleeve-shaped outer part and constitutes the first supporting means, and a first and another wall portion are formed respectively between the pinched region and the two end regions of the sleeve-shaped outer part.
