Claim 8:
9. A cap system for a refill capsule, the cap system comprising:
the plug of claim 1; and
a cap assembly comprising:
an inner wall defining a conduit through the cap assembly, the conduit extending from an upstream end to a downstream end; an outer wall surrounding the inner wall along at least a first portion of its length, wherein the outer wall is spaced from the first portion of the inner wall to define a circumferential void between the inner and outer walls extending from an open downstream end to a closed upstream end;
a connecting wall extending between the inner and outer walls to prevent fluid flow through the void, the connecting wall forming the closed upstream end of the void;
wherein the cap assembly further comprises a closure member configured to seal the conduit, the closure member comprising an upstream side and a downstream side,
wherein the closure member is sealed to the inner wall with a peripheral frangible connection located between proximal and distal ends of the conduit,, wherein the frangible connection extends in a plane P, which is orthogonal to a longitudinal axis (A) of the conduit; and
wherein the plug is disposed within the cap assembly such that the outer wall of the cap assembly surrounds the plug, and the inner wall of the cap assembly extends into the plug recess, and
wherein the proximal abutment surface of the plug is aligned with and opposes the bearing surface of the closure member (208).
