Applying sealing cpd. to can body and lid before making double seam joint

摘要

The technical field of the invention is the application of sealant onto or into a folded-seam closure (D) of a metal can. Such sealants have previously been introduced into the U-shaped lid flange and dried. By contrast, the invention proposes that the compound - the sealant (10) - be applied (10a) to the base flange (1a), the base (1) of the metal can being dipped into a current of fluid sealant (10) or at least brought into contact with it at the surface. This substantially improves the precision of the dosing and the exact amount of applied sealant.
