A vaporizer for delivery of a volatile medium to a gas flow, the vaporizer comprising: a gas delivery unit () which receives a flow of gas and provides a flow of gas containing a metered amount of a vaporized medium; a reservoir unit () which contains a volatile medium and maintains a supply of the vaporized medium, wherein the reservoir unit is selectively fluidly connected to the gas delivery unit; a gas sensing unit () for sensing a flow rate and/or composition of the gas flow; a vaporized medium sensing unit () for sensing a flow rate of the vaporized medium; a manifold () which includes flow paths for the vaporized medium and fluidly connects the reservoir unit and the vaporized medium sensing unit; and a control unit () for controlling a flow rate of the gas flow and an amount of the vaporized medium which is metered into the gas flow.

Vaporizer

A can end (1) having an openable portion (14) defined by a score line (13), has a ring pull defining an aperture in which is retained a token (16) which may be removed as proof of purchase to qualify the purchaser for a prize or other premium offer. The token (16) is preferably made from a plastics material which is retained by clinching of peripheral material of the ring pull, and may be marked with indicia.

Containers

A combined pull tab and token is disclosed in which the token includes a body and the pull tab includes a clinched peripheral curl portion. The pull tab is adapted to be attached to a container wall, and a portion of the token is engaged within the clinched peripheral curl portion of the pull tab.
