摘要：
The invention provides a mould core and injection moulding apparatus for the production of a preform using a mould core which in the zone for defining the neck part of the preform comprises a combination of a raised portion and a shallow groove with a depth of 0.01 to 1 mm provided in the raised portion, for defining an internal attachment means in the neck of the preform. The invention also provides a preform and a container made from the preform, with internal attachment means in the neck. The internal attachment means is carried out rotation symmetrically with respect to the longitudinal axis of the preform. The combinations with an insert piece, preferably a pouring spout, flexible hose or dosing cap, have also been described. Furthermore, the invention provides an injection moulding method for the preform production and a stretch blow moulding method for the container production.
