PCT No. PCT/AU80/00087 Sec. 371 Date Jul. 20, 1981 Sec. 102(e) Date Jul. 20, 1981 PCT Filed Nov. 14, 1980 PCT Pub. No. WO81/01544 PCT Pub. Date Jun. 11, 1981.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.
