Cartridges having interiorly positioned zones of reduced thickness

A cartridge container containing a substance for preparation of a beverage comprising:

• a body comprising a base, a sidewall and a rim, wherein the sidewall extends from the base to define a container interior, to define a container opening which opposes the base and to define a body shape selected from the group consisting of a frustum and a hemisphere and wherein the sidewall extends from the base to the rim and the rim extends from the sidewall in a direction away from the sidewall;
• a substance for preparation of a beverage contained within the container interior;
• and
• a cover membrane member affixed to the rim to cover the opening and to contain the substance in the container interior and wherein the cover member defines both a container cover member outer solid surface and a container cover member interior surface and wherein the container cover member contains a plurality of perforations which define openings in the container cover member which extend for a distance from the container cover member interior surface through the container cover member towards the container cover member outer solid surface to provide localized absence of a plurality of portions of the cover membrane member so that the cover membrane member has a plurality of zones which comprise a plurality of localized portions of reduced thickness and 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.

A cartridge container containing a substance for preparation of a beverage comprising:

• a body comprising a base member, a side-wall and a rim, wherein the sidewall extends from the base member to define a container interior, to define a container opening which opposes the base and to define a body shape selected from the group consisting of a frustum and a hemisphere and wherein the sidewall extends from the base to the rim and the rim extends from the sidewall in a direction away from the sidewall;
• a cover member affixed to the rim to cover the opening;
• a substance for preparation of a beverage contained within the container interior by the body and cover membrane;
• and
• wherein one of the base member or the cover member defines one container outer surface and one container interior surface and wherein the one member contains a plurality of perforations which define opposing openings in each of the outer and interior surfaces and wherein the openings extend for a distance from each surface through the one member towards a member solid portion positioned between the outer and interior surfaces to provide localized absence of a plurality of portions of the one member and an intermediately positioned member solid portion so that the one member has a plurality of zones which comprise a plurality of localized portions of reduced thickness and 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.
