Patent

CA 2275903

The present invention relates to a medicament container for storing a liquid medicament, such as insulin, the container comprising a distal and a proximal end portion and a wall, at least two opposite portions of the wall being of a polymer material. The thickness of the polymer wall portions is between 0.3 mm and 3 mm, and the light transmission through the polymer wall portions at 400 nm are at least 25 %. The polymer wall portions are of a material comprising at least 70 % by weight of a linear optionally branched polyolefin material, the olefin monomer being selected from ethylene, propylene, butylene or a mixture thereof. The material has a crystallinity above 35 %. The container of the polymer material is substantially inert to the medicament, and furthermore, the container is transparent, whereby it is possible visually to inspect the content of the container to make sure that the medicament is not crystallised or polymerised. Furthermore, the walls of the container provide a good barrier against m-cresol-phenol-benzyl alcohol preservatives and water, respectively. The invention also relates to the use of such medicament container, and a medicament container at least partly filled with medicament.

Contenant à médicament pour stockage de médicament liquide comme l'insuline, avec extrémités distale et proximale et enceinte, au moins deux parties opposées de l'enceinte étant en polymère. L'épaisseur de ces parties oscille entre 0,3 et 3 mm, et la transmission de la lumière dans lesdites parties à 400 nm est d'au moins 25 %. Ces parties sont en matériau comprenant au moins, en poids, 70 % de matériau à base de polyoléfine linéaire éventuellement ramifiée, le monomère d'oléfine étant choisi parmi: éthylène, propylène, butylène ou un mélange de ces constituants. Le matériau a une cristallinité supérieure à 35 %. Le contenant en polymère est sensiblement inerte par rapport au médicament, et il est transparent, ce qui permet de contrôler visuellement le contenu pour vérifier qu'il n'y a ni cristallisation ni polymérisation du médicament. Les parois sont une barrière efficace contre les préservateurs à l'alcool de type m-crésol/phénol/benzylique et l'eau, respectivement. On décrit aussi l'utilisation du contenant et, enfin, le contenant considéré au moins rempli en partie avec un médicament.
