Abstract
A beverage container in the form of an aluminium can has a top plate in which a dispensing aperture is formed by pulling a tab so as to inwardly displace a tongue portion. A filtering means is resiliently mounted within the container so as to be deployed at a location traversing the dispensing aperture after the tongue portion has been inwardly displaced. The filtering means may be a perforate plate and may have perforations defining a competition visual indication whereby the token becomes visible only after the container is opened.
