A container set comprises a first container (21) adapted to be reused by being refilled with the contents of a second container (22) containing a product of a volume not exceeding the volume of the first container. The two containers (21 and 22) comprise mouth parts (33, 27) with guide faces allowing a coupling together of the containers in a position in which said containers are mutually immovable in radial direction. Furthermore, the mouth parts (33, 27) of the containers (21, 22) comprise co-operating sealing faces preventing the contents from leaking into the surroundings when the coupled containers are manipulated in order to transfer the contents from the second container (22) to the first container (21). The second container (22) preferably has a substantially superelliptic shape in any cross-sectional view parallel to the support engaging force of the container when the container is filled with the liquid product.
