Abstract
A method of forming a cup-shaped body for a beverage capsule comprising the steps of: a) in a first stage drawing a sheet of material into a cup-shaped body preform; and b) in a second stage transforming the cup-shaped body preform into the cup-shaped body; wherein after the first stage the cup-shaped body preform comprises a base and a preformed side wall which extends from the base to a rim; wherein the preformed side wall comprises: an outwardly-extending step proximate the rim; a primary side wall section extending between the base and the outwardly-extending step; and a secondary side wall section extending between the outwardly-extending step and the rim; wherein in the second stage the preformed side wall is deformed such that the cup-shaped body comprises the base and a side wall which extends from the base to the rim; wherein the side wall comprises: an annular trough; a first side wall section extending between the base and the annular trough; and a second side wall section extending between the annular trough and the rim.
