Abstract
Cup-shaped packing containers are used for the packaging of e.g. yoghurt. The packing containers are provided with lids which can be removed from the packing container in that e.g. the seal between lid and cup portion is broken. After opening the lid cannot be used for the reclosure of the packing container. This is a disadvantage, which is overcome in accordance with the invention, in that the lid is adapted so that it fits closely against the inside of the cup portion in an area situated below the line along which on opening of the packing container the lid is intended to be separated from the cup portion. By an appropriate dimensioning of the lid and the cup portion the lid can be retained by and seal the cup portion after the opening, which is an advantage if a part of the contents is to be saved for later consumption.
