Abstract
Container assembly comprising a container and a closure, wherein the container is made of a crystallisable polymer material and comprises a neck portion with an outer cap surface and defines an outlet opening, the neck portion being configured for receiving the closure, wherein the closure includes a closure cap made of a crystallisable polymer material and has an inner cap surface, the closure cap being matched to the neck portion of the container to cover the outlet opening in a closed state, wherein the inner cap surface of the closure cap contacts the outer cap surface of the neck portion when the container assembly is closed, and wherein the material of the inner cap surface of the closure cap and/or of the outer cap surface of the neck portion is crystallised, to allow the container assembly to be opened after being closed for an elongated period of time.
