ABSTRACT:
An end wall 9, for attachment to a container, has a central panel 10 and surrounded by a channel portion 11 which includes a deposit of solder 19 in the form of a paste of solder and flux. The can end 9 is joined by a double seam 23 to a sidewall 12 of a container body. Heating of the double seam melts the solder to create a soldered joint between the end wall and sidewall. The invention is to be used in the manufacture of containers requiring strong double seams and may be used to make containers for carriage of dangerous goods. Apparatus for applying solder pastes to can ends is described in which paste is urged from a pot against convex surface 37 before passing through oulet nozzles 38 onto a can end.
