Abstract: An ampoule holder comprises a body part 1 and a head part 2 which are connected together by a pair of hinge strips 3 and a breakage link 4. A glass ampoule 7 is inserted, stem first, through an opening 6 in the base of the body portion 1. The body of the ampoule is forced past inwardly extending projections 8 until the lower end of the ampoule snaps past these projections and the shoulder at the top of the body of the ampoule 7 abuts against the curved hinge parts 3. The base of the ampoule will then be raised above the projections 8. The stem 10 of the ampoule is gripped within the head portion 2 of the holder by internal ribs or spines 11, so that the neck 9 of the ampoule is aligned with the breakage link 4.
