Document Type and Number:
WIPO Patent Application WO/2010/052249
Kind Code:
A3
Abstract:
A metal closure is described, in the form of a foil lid (1) bonded to a metal annular component (such as a container body or separate intermediate ring). The foil lid (1) and annular component are made of dissimilar metals, with the closure adapted to prevent bimetallic corrosion at the interface between the dissimilar metals of the foil lid and the annular component. The closure is adapted such that the lid comprises a peripheral wall which is upstanding from the annular component such that a gap is maintained between the annular component and an exposed metal peripheral edge of the lid. Further aspects of the invention include: i. a method for making such a metal closure; and ii. an apparatus for making such a metal closure.
