Glass ampoule surrounded by electrostatically charged plastic film casing with intentional break points near constriction, reduces probability of injury, prevents leakage of contents and immobilizes glass splinters at source

摘要

A casing (10) extends over the constriction (3) of the ampoule neck (4). An Independent claim is included for the method of ampoule manufacture. Preferred features: The casing reaches to the tip (5) of the neck and comprises paper, optionally lined, or transparent thermoplastic film. It is adhered-on or applied as shrink film. It simultaneously forms a label, or covers an applied label. The casing is a winding of 3-10 turns. It has a weakened, especially perforated section for intentional breaking, located between body and neck. Where the casing covers the ampoule body it is internally coated with adhesive.
