Abstract
A closure assembly for a mouth and neck portion of a container for liquid has a sleeve adapted to lie substantially concentrically with respect to the mouth and provided with a mechanism for fixing the sleeve on the container. A first outer sleeve is coaxially mounted over the sleeve and a second outer sleeve separate from the first outer sleeve and substantially tight fit with a container closure member. The first and second outer sleeves are axially aligned and have respective initially adjacent portions. A mechanism is provided for spacing apart the initially adjacent portions of the first and second outer sleeves upon reclosure of the assembly after an initial opening of the container.
