Abstract: The closure for blow-moulded wide-necked plastic drums (2) uses a collar-type solid plastic closure ring (9) which rests against the underside of a solid border (10) which projects radially outwards from the drum wall with spacing below the drum opening, and a counter-ring (11) which is likewise made of plastic and rests on a flange (12) moulded onto the outer edge (4) of the lid at the bottom. Moulded onto the closure rings (9, 11) are retaining sleeves (13, 14) which are distributed over the circumference and engage in corresponding bores (15, 16) in the drum border (10) and in the lid flange (12). The closure rings (9, 11) and the retaining sleeves (13, 14) moulded thereon have conical through-bores (17, 18). To close the lid (1) fitted onto the wide-necked drum (2), tensioning bolts (19) made of plastic or metal are pressed from above by means of a pressing tool into the congruently aligned conical bores (18, 17) of the two closure rings (11, 9), the closure ring (9) resting against the drum border (10) being supported by an appropriate device. By means of the tensioning force exerted by the tensioning bolts (19), the lid seal (8) is pressed against the opening edge of the drum neck (3). <IMAGE>

Abstract: An ammonia-free reducer is added to cupric ions to achieve reduction to cuprous hydroxide in a process for the deposition of metallic copper on a catalytically activated surface by rapidly reducing cupric ions in aqueous solution to cuprous hydroxide, without substantial reduction to elemental or metallic copper, and thereafter effecting controlled disproportionation of the resultant cuprous hydroxide to bring about the deposition of metallic copper. The ammonia-free reducer is preferably hydroxylamine or its salts in the presence of a water soluble alkali metal- or alkaline earth metal- hydroxide, more preferably sodium hydroxide. The process of reduction of cupric ions is further effected by adding to the solution an antiagglomerating agent for controlling the dispersion of the cuprous hydroxide, preferably a polyol such as sorbose or invert sugar. The process of disproportionation of the cuprous hydroxide is further effected by adding an activator comprising a hydroxycarboxylic acid or salt thereof, preferably citric acid or malic acid with sulfuric acid, to bring about the deposition of metallic copper principally on the catalytically activated surface, wherein the hydroxycarboxylic acid or salt activator is present in solution in an amount no greater than about one mole per mole of cuprous hydroxide.
