A container is provided for substances that contain an antibacterial compound. The container is comprised of a tube body and a tube shoulder that includes a tube nozzle. The tube body may have a laminate structure. The rube shoulder may be comprised of an alkene based polymer such as a polyethylene or a polypropylene. Such alkene based polymers have a high absorptivity for antibacterial compounds such as triclosan. It has been found that the absorptivity for triclosan can be reduced through the use of at least one of polytrimethylene naphthalate, polyethylene naphthalate and acrolonitrile/methacrylate as the surface contacting the composition containing the antibacterial. This surface can be a film on the tube shoulder/ nozzle, the full structure of the tube nozzle, an insert in the rube nozzle or a co-injection molded surface on a shoulder/ nozzle. The absorption is less than 10 mg/dm2.

L'invention concerne un récipient destiné à des substances qui contiennent un composé antibactérien. Le récipient est composé d'un corps de tube et d'un épaulement de tube qui comprend une buse de tube. Le corps de tube peut posséder une structure stratifiée. L'épaulement de tube peut être constitué d'un polymère à base d'alcène tel qu'un polyéthylène ou un polypropylène. Ces polymères à base d'alcène présentent une capacité d'absorption élevée pour des composés antibactériens tels que le triclosan. On a découvert que la capacité d'absorption de triclosan peut être réduite en utilisant au moins un composé parmi le naphtalate de polytriméthylène, le naphtalate de polyéthylène et l'acrylonitrile-méthacrylate comme surface en contact avec la composition contenant l'agent antibactérien. Cette surface peut être un film sur l'épaulement/la buse de tube, la structure complète de la buse de tube, un insert dans la buse de tube ou une surface moulée par co-injection sur l'épaulement/la buse. L'absorption est inférieure à 10 mg/dm2.
