<p>The envelope (1) is opaque and gas-tight and contains an oxygen-free atmosphere. The vessel (2) is closed such that it is fluid-tight and has deformable walls (10), consisting of plastic material, and a dropper nozzle (11) provided with the closure (13). The envelope is preferably formed from a three-layered sheet, in which a metal foil (7) is arranged between a wear-resistant plastic layer (6) and a layer (8) which permits the package to be sealed at the edges by welding. The package ensures a high degree of protection of the contents against light, oxygen and breakage, inter alia. <IMAGE></p> |
