ABSTRACT:
The invention relates to a container neck (10) and closure (12), particularly useful for foil-sealed containers. The neck (10) and closure (12) include complementary threads (14, 16) or projections and complementary tapered surfaces (18, 20) which are adapted to form an interference fit and seal the closure (12) to the neck (10) at a region clear from the lip (30) of the neck (10) and the crown (120) of the closure (12). Any foil seal (28) present on the container neck (10) remains free from contact with the closure (12) during application and tightening. Preferably the neck (10) includes a recessed lip (30, 32) further to protect the seal and to inhibit drop formation. An outer edge of the container lip may be chamfered to provide a pull tab on the foil seal. Additionally, the foil may be of a larger diameter than the lip of the container, so that it provides an overhanging edge of foil to facilitate the removal of the foil, but not of such a large diameter that it touches the inner surface of the closure.
