Abstract (en)
[origin: EP0771734A1] A container, especially a bottle (1) with a dispensing head (3) and a cap (5), an airless pump (4) and a valve in the dispensing head. All or part of the container's wall is made from a plastic material with a high level of air permeability, such as an injectable thermoplastic polymer e.g. polyolefins, PVC or technical polymers. The base of the container can be made from a material which is highly permeable to air, e.g. a silicone elastomer, or the container wall can be loaded with a material which enhances air diffusion, such as chalk. The portions of the container in contact with the dispensing head or cap are treated with an anti-oxidant or antiseptic contact agent which does not migrate into the solution.
