Abstract
A container is provided for substances that contain an antibacterial compound. The container has a tube body and a tube shoulder. The tube shoulder is made 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. The shoulder includes a barrier unit. The barrier unit is made of a polymeric material such as polytrimethylene naphthalate, polyethylene naphthalate and acrolonitrile/methacrylate. This barrier unit can be a film on the tube shoulder or a co-injection molded insert in the shoulder. The absorption is less than 10 mg/dm2.
