Abstract: A plug for use in a cap assembly of a refill capsule is disclosed. The plug (300) generally comprises a hollow tubular body (302) with an open proximal end that is surrounded by a first rim (304) that provides a proximal abutment surface for bearing against a frangible sealing component of a cap assembly. A tubular skirt wall (306) is arranged coaxially with respect to the tubular body, and extends around the skirt wall (306) to form a plug recess (308) between the skirt wall (306) and the tubular body (302). The skirt wall (306) extends from a skirt distal end at which the skirt wall (306) is connected to the tubular body (302), to a free proximal end. The free proximal end of the skirt comprises an outwardly extending flange (310) comprising a distal facing abutment surface (312) for abutting a rim (406) of a refillable vessel (400).

Abstract: A cap assembly for a refill capsule and associated refill system is disclosed. The cap assembly (200) comprises an inner wall (202) defining a conduit (203) through the cap assembly (200) and an outer wall (204) surrounding the inner wall to form a circumferential void between the inner and outer walls (202, 204). A connecting wall joins the inner and outer walls (202, 204). The cap assembly (200) further comprises a closure member (208) which is sealed to the inner wall (202) with a peripheral frangible connection (210). The frangible connection (210) is disposed between a first peripheral recess (222) formed between the inner wall (202) and the downstream side (208b) of the closure member (208), and a second peripheral recess (224) between the inner wall (202) and the upstream side (208b) of the closure member (208).

Abstract: A cap system for a refill capsule for a container for concentrated cleaning fluid is described. The cap system comprises a cap assembly (200) comprising a conduit (203) sealed by a closure member (208), frangibly connected to an inner surface of the conduit (203). The frangible connection extends in a first plane, which is orthogonal to the longitudinal axis (A) of the conduit (203). The cap system further comprises a plug (300), disposed at least partially within the conduit (203), the plug comprising an abutment surface (305) for bearing against the closure member (208), to break the frangible connection (210). The abutment surface (305) extends in a second plane, which is parallel to the first plane in which the frangible connection (210) extends.
