Abstract

A threaded container has non-overlapping thread portions 4a and 4b of a multi-start thread such that at the parting line 7 of the external mould parts for the moulded container l there is a zone in which the generatrices of the container rim do not intersect any of the thread portions of the multi-start container external thread. This facilitates parting of the external mould parts of the container.
Preferably the container rim is closed by a closure having an internal multi-start thread comprising thread portions which are overlapping such that in every position of the generatrix of the closure skirt the generatrix intersects a thread portion of the skirt.
