ABSTRACT:
A glass bottle (1) fitted with a narrowed neck (2) which can be filled under pressure with chiefly a medically active substance sprayable by aerosol and with a propellant and which exhibits an opening which may be closed using a dosage valve (5). This glass bottle (1) has a sprayed-on synthetic coating (4) to protect it against shattering and splintering, preventing the user from being injured by the broken bottle. To substantially enhance this safety, the neck (2) of the bottle (1) has been fitted with a bulge like edge (3) at the opening which is also coated with the synthetic material (4) and onto which the dosage valve (5) is mechanically attached by turning. Furthermore, the coating (4) consists of an elastic synthetic material with pronounced increased shrinkage properties used for the summoning of pre-stressing force on the glass body (1) and it exhibits several hole-like pressure relieving openings (7) permitting rapid pressure release in case of shattering.
