An O-ring is attached to a container such as a bottle or can which contains a soft drink intended for consumption by a single individual. The O-ring has an inner diameter less than the outer diameter of the container and is composed of material which resiliently deforms so that the O-ring may be stretched to encircle the container after which, when loosened, it squeezes into contact with the container and remains attached to it. The O-ring is provided with indicia such as a name-tag or a distinctive colour or combination or colours in order to distinguish the container to which the O-ring is attached from other like containers.
