Abstract
The invention relates to a container made from a material, which is shaped in the fluid state and hardened to a given shape and which is provided for receiving a product or article and has a closure part (4). To simplify the manufacture of the container, the closure part is placed over at least one container wall (1) and is shaped from one piece therewith, so that the closure part is inseparably arranged on the container and is movable in order to remove the content. The container and the closure part are made from the same material.
