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 container having a cylindrical pouring nozzle with an external thread and with a stop; a cap with an internal thread which can be screwed onto the external thread of the pouring nozzle as far as an end position in which the cap bears in the direction of rotation on the stop of the pouring nozzle; and a seal made of a material which is softer than a material of the cap and a material of the pouring nozzle. The seal is fixedly connected to the cap and has a first sealing element which, with the cap screwed on, is arranged in a radial direction between the cap and pouring nozzle and bears on a lateral surface portion of the pouring nozzle.

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 dispensing closure for a product container includes a plastic closure body having a top wall with a dispensing opening which is arranged in line with a dispensing passage of the container. The closure includes a self-closing valve embodied as a membrane made of a plastic foil. The membrane has a valve portion, which in use can assume an open position under influence of product pressure, and an attachment portion surrounding the valve portion. The attachment portion of the valve is sealed to an annular support surface integrally formed in the closure body along the periphery of the opening or being formed on a plastic annular insert part that is connected to the closure body along the periphery of the opening. The seal between the attachment portion and the support surface includes an annular groove and an inner annular seal zone adjoining the annular groove on a radial inner side.

Abstract: A liquid dosing device for a container includes a dosing chamber having a front end and a back end. An outlet passage is located at the front end. A plunger is located in the dosing chamber, divides it in a front and a back space, and is moveable between a forward position in which the plunger closes off the outlet passage, and a backward position, in which the front space has a maximal volume. An inlet passage provides fluid communication between the front space and the container. A timer passage provides fluid communication between the container and the back space. A release passage, being greater than the timer passage, provides fluid communication between the back space and the container. A valve assembly at the release passage includes a valve seat located at the back end of the dosing chamber.

Abstract: The invention relates to a closure assembly configured to be mounted on a neck of a container, which closure assembly includes a cap with a dispensing opening and a self-closing dispensing valve attached to the cap such that it is located adjacent the dispensing opening, and wherein the dispensing valve is a disc of foil material having a central valve area in which at least one self-closing slit is located and an annular peripheral attachment area extending around the central valve area, with which attachment area the dispensing valve is attached to the attachment area of the dispensing cap such that its central valve area aligns with the dispensing opening of the dispensing cap to close off that dispensing opening, and wherein an annular rib offsets the central valve area of the dispensing valve relative to a substantially flat attachment area of the cap.
