Abstract: A method of and means for manufacturing an article, such as a toothpaste tube having a captive cap, by injection moulding. An elongated core (2) is projected into the hollow of a die (1) to engage an aligning surface (5) on the core (2) with a mating aligning surface (6) on the die (1) at commencement of the injection moulding cycle. Then during continuation of the moulding cycle disengaging the aligning surfaces are disengaged to form a membrane (33) between the disengaged surfaces.

Abstract: A paste dispenser having a body (1) of plastics with an expanded head (8) having a cap (5) formed integrally therewith by a hinge adapted to engage the head part of the tube with a snap fit, the tube having a nozzle (3) for discharge of the contents, closed by a hollow member (14) in the cap, the cap and head a dimension in width some what similar to the crimped end (9) of the tube being moulded by using in the dies at least one channel (37) to give longitudinal flow of the plastics material during moulding but latterally spread from the channels to enable a long controlled thin wall to be formed.
