Abstract
A dispenser () has a source () of medicament with a transparent reservoir () of glass sheathed in a transparent plastics material shrink wrapping (), which provides an enclosure against explosion of the glass in the event of accidental breakage of the glass. The reservoir contains not only a liquid medicament (), but also a gaseous propellant liable to cause the glass to explode if broken. A valve () of the source is within a body () of the dispenser. The valve is attached to the reservoir by a crimped on aluminum sleeve (). With the dispenser inverted the level () of the medicament () is within the tapered tip when the medicament is close to being used up. As use of the dispenser continues, the level falls progressively faster, giving the user an indication that a fresh dispenser will soon be required.
