FIELD: medical engineering. SUBSTANCE: device has proximal and distal ends and wall. At least two opposite parts of the wall are manufactured from polymer material. Polymer wall part thickness is 0.3-3 mm large. Light transmission capacity through 400 nm polymer walls is not less than 25%. The polymer wall parts are manufactured from a material comprising at least 70% by mass of linear or, optionally, branching polyolifin material, olefin monomer being selected from ethylene, propylene, butylene or their mixture. Material crystallinity is higher than 35%. Polymer container is essentially inert with respect to medicament and transparent so that container contents is visually controllable to be sure that the medicament is not crystallized or polymerized. Container walls make good barrier for preservatives like metacresolphenol benzyl alcohol and for water, respectively. EFFECT: satisfactory barrier for metacresol, benzyl alcohol and water; long storage life of medicaments in the container. 17 cl, 3 tbl
