Abstract
Abstract A wrapper having a central absorbent area is wrapped around a frangible ampoule containing an inhalant. The absorbent area substantially surrounds the ampoule, and the wrapper projects from the opposite ends of the ampoule. A pressure sensitive adhesive on the inner surface of the wrapper around its central area sticks the inner end of the wrapper to the ampoule and also sticks the outer end of the wrapper to its own outer surface. The projecting portion of the wrapper at each end of the ampoule is flattened on itself to form flat layers of wrapper stuck together by the adhesive. The portion of the wrapper surrounding the ampoule is porous so that when the ampoule is broken fumes or vapor therefrom can escape through the wrapper.
