ABSTRACT:
A cartridge which contains a substance for preparation of a beverage has a cover membrane member which covers an opening of a container body for containing the substance within the container interior. The body has a base and a sidewall which extends from the base to define a container interior, and the sidewall defines the opening at a position opposing the base. The membrane is affixed to a rim which extends from the sidewall in a direction away from the sidewall. An interior container surface of either the base or the cover membrane member contains a plurality of perforations which define openings which provide localized absence of a plurality of portions in the base or cover membrane member to provide a plurality of localized portions of reduced thickness so that when a fluid pressure for extraction of the substance for preparation of a beverage is applied, the localized portions of reduced thickness tear and open for beverage passage.
