Pump for applying an increased or reduced pressure to a container. The pump is provided with a plate-like part which reacts to the pressure difference between the container and the environment. This part can preferably adopt two stable positions, and a change is signalled. This change can be brought about, for example, by the sound generated as a result of the plate-like part turning over. The pitch and the like of the sound can be influenced by arranging the plate-like part in a hollow piston and providing the latter with openings leading to the environment.

Pump with pressure-indication means

Pourer consisting of an elongated, tubular part of plastic material. This part of plastic material is made resilient and has an external diameter greater than that of the associated bottles. The tubular part is provided with a split, as a result of which the diameter can be reduced to some extent and the pourer can be accommodated with a clamping action in a bottle. This clamping can be even further promoted by providing ribs. The pourer is provided with a search point to facilitate introduction into a bottle and the pouring end is flared.
