Abstract

Blow moulding and injection methods are disclosed for making a hollow, shaped article such as a dispenser for a flowable material, from plastics or glass. For blow moulding, a parison 87 (figure 11) or 43 (figure 7) is positioned in a mould cavity 91 or 42 which has a closed end 90 or 49. A blow pin 89 or 47 is extended into the parison, which is preferably clamped between a mould collar 46 (figure 7) and the blow pin 47. The opposite end of the parison is compressed by the blow pin to conform to the shape of the blow pin and mould cavity, and is inflated so that is assumes the shape of the mould cavity and, after cooling, is ejected from the mould. The shaped article can also be injection moulded between a complex-shaped mould and core. The preferred article is a dispenser 80 (figure 10) having a conical nozzle 83 and cap 84 which are broken off the dispenser body for screwing into threads 81. The nozzle 83 can be externally stepped.
