Abstract:
A medicament container for storing a liquid medicament comprising one or more active medicaments, water and at least one preservative, the container comprising a distal and a proximal end portion and at least one wall defining an interior space for such liquid medicament, said at least one wall having at least two opposed sections composed of a polymer material, said polymer wall sections having a thickness of between 0.3 mm and 3 mm, a light transmission at 400 nm of 25% or more, measured through both of said opposed container wall sections when the container is filled with water, using a standard spectrophotometer and air as reference, the polymer wall sections being of a material comprising at least 70% by weight of a co-polymer material composed of aliphatic cyclic or bicylic hydrocarbons with 5 to 7 membered ring or rings, and ethylene or propylene, and wherein the ethylene or propylene is present in the polymer material in an amount of at least 20% of the at least 70%, said wall sections further having a glass transition temperature above 50Â° C., measured by differential scanning calorimetry, by cutting pieces from the container walls and heating them in an aluminium pan from 10Â° C. to 270Â° C. at a scanning rate 10Â° C./mm, the glass transition temperature being determined as the temperature at the inflection point; and a density of 0.95 g/cm3 or more.
