The two-sided plastic stopper has a lower portion (1) that can be secured to the neck of a container (14, 15) and a measuring cup (2) which can be reversed and set on the lower portion so as to form a seal, this serving as a cap. A tubular spout (11) is surrounded by a concentric annular wall (12).

The two-sided plastic stopper has a lower portion (1) that can be secured to the neck of a container (14, 15) and a measuring cup (2) which can be reversed and set on the lower portion so as to form a seal, this serving as a cap. A tubular spout (11) is surrounded by a concentric annular wall (12). In this way a trough (18) is formed together with the connecting wall (13) between the spout (11) and the annular wall (12), this trough having a drain (19) that leads back to the container. Within the base of the measuring cup (21) there is a centrally arranged annular wall (23) in the form of a sealing plug. This sealing plug (23) and the tubular spout (11) fit together in a form fit so as to seal each other and have connecting means that act together, preferably threads (17, 24, respectively).
