Patent ID: 8651012

Claim:
A beverage producing system comprising: a capsule containing beverage ingredients and having a center axis; a cup-shaped body comprising a top wall and a sidewall having an outer surface, with the top wall and sidewall configured for defining a cavity that contains beverage forming ingredients therein and with the sidewall including a rim-like flange forming a periphery of the sidewall, which flange includes transverse and axial extensions; a foil member sealed to the flange of the body to retain the beverage forming ingredients in the cavity; and a capsule-based beverage producing device provided with a member for injecting a liquid under pressure into the capsule, a member for draining a beverage from the capsule, and an enclosing member that is movable from an opened state to a defined closed state, in which the enclosing member encloses the outer surface of the capsule; and a dedicated ring-like sealing member which is not part of the foil member and is present on the rim of the flange opposite the foil member to form part of the capsule, which sealing member is compressible when engaged by the enclosing member in the closed state; wherein the dedicated ring-like sealing member is formed upon the transverse extension of the flange such that when compressed by the enclosing member in the closed state provides a sealing engagement that compensates for clearances between the enclosing member and the capsule which would otherwise exist when the enclosing member is in the closed state such that the sealing member assures that the liquid can only flow through the capsule and in contact with the beverage ingredients to form a liquid beverage.
