摘要： An injection moulded thermoplastic preform for blow moulding to form a container, the preform comprising a lower closed base portion, a hollow body portion, a hollow transition portion between the lower closed base portion and the hollow body portion, and an upper open end portion adjacent to an upper part of the hollow body portion, wherein the closed base portion comprises a central portion which extends over at least 50% of an internal radius of a lower end of the hollow body portion and is either substantially flat or has a shallow concave or convex internal curvature, and the transition portion comprises an upwardly and radially outwardly tapering portion extending away from the central portion to connect to the hollow body portion, the tapering portion being inclined at an angle of from 1 to 20 degrees to a longitudinal axis of the preform and the tapering portion increasing in thickness from the central portion to the hollow body portion. Also disclosed is a method of injection moulding the thermoplastic preform.

摘要： A method of injection moulding an article, the method comprising the steps of: (a) providing an injection mould comprising a plurality of mould parts defining a mould cavity of the injection mould, the plurality of mould parts including first and second movable mould parts, the injection mould further comprising an injection inlet for injecting molten thermoplastic resin material into the mould cavity, wherein the injection inlet is located in the vicinity of the first movable mould part and the second movable mould part is remote from the injection inlet; (b) disposing the first and second movable mould parts in a first configuration so as to define a first intermediate moulding cavity, in which first configuration the first movable mould part is in a first rearward position and the second movable mould part is in a first forward position; (c) injecting molten thermoplastic resin material into the first intermediate moulding cavity through the injection inlet to fill the first intermediate moulding cavity with the molten material; (d) closing the injection inlet; (e) after commencement of the injecting step and at least partly after the closing step, moving the second movable mould part from the first forward position to a second rearward position; (f) moving the first movable mould part from the first rearward position to a second forward position; and (g) moving the second movable mould part from the second rearward position to a third forward position thereby to dispose the first and second movable mould parts in a final configuration so as to define a final moulding cavity of the injection mould filled with the molten material, the final moulding cavity defining a cavity outer surface which defines the outer shape of the article to be moulded.
