Thermoplastic bucket is moulded with its handle in position, using female and male mould tools which both have flat surfaces facing each other; these surfaces have grooves which are connected to the central cavity areas at diametrically opposite points where pins project from the male tool; these grooves mould the handle. The desin of the mould produces the bucket with its positioned handle in one shot yet leaves the handle free to pivot; its moulding cycle is short; the tools are relatively simple and limited in number of parts so that maintenance is minimal.
