Abstract (en)
[origin: EP0806373A1] The sealed cup, designed to contain a substance used to prepare a drink, e.g. ground coffee, has a flat base (2), conical sides (3) with an upper rim (4), and a lid (5) sealed to the rim. The cup is made from aluminium or an aluminium-based alloy e.g. of iron, silicium, manganese, magnesium, chrome, copper or zinc, with the aluminium content at least 90 per cent. The base of the cup has zones of reduced resistance, created by scored lines in the shape of concentric circular arcs of the same or different radii, a spiral, wavy lines or radial segments. The zones of reduced resistance have a thickness equivalent to half that of the main surfaces, which are between 50 and 150 microns thick, with the lid of thinner material.
