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 self-closing dispensing valve is made of an elastic material and includes a valve head with a dispensing orifice, a circular peripheral retaining flange spaced apart from the valve head in an axial direction, and a connector sleeve integrally connected with the valve head on one end and the retaining flange on another end. The elastic material is a plastomer or a thermoplastic elastomer. The connector sleeve is substantially form stable. The valve head is connected to an upper end of the connector sleeve by a hinge portion that is U-shaped in cross section. The wall thickness of the hinge portion is smaller than the wall thickness of the connector sleeve and is staggered at the transition between the connector sleeve and the hinge portion. Alternatively, if the connector sleeve is omitted, then the valve head is directly connected to the retaining flange.

Abstract: A self-closing dispensing valve is made of an elastic material and includes a valve head with a dispensing orifice, a circular peripheral retaining flange spaced apart from the valve head in an axial direction, and a connecting sleeve integrally connected with the valve head on one end and the retaining flange on another end. The dispensing orifice is formed by at least three slits in the valve head, where the slits converge at a centre of the valve head and are angularly evenly distributed around the centre of the valve head. The valve head includes a number of lobes, where in each of the lobes at least one of the slits is formed. Each of the lobes has a tip region on a radial outer end of the lobe, where the tip regions of the respective lobes lie approximately on an imaginary circle.

Abstract: A valve carrier ring for carrying a self-closing dispensing valve is adapted to be assembled with a closure body of a container. The valve carrier ring includes an annular seat portion including a support surface for supporting a retaining portion of the valve and a circumferential wall located radially outwards of the support surface and extending coaxially with the support surface. The circumferential wall has a preformed radial protrusion adapted to extend over the retaining portion of the valve for providing a preliminary retention of the retaining portion in the seat portion. A snap bead is formed at a radial outer side of the valve carrier ring adapted to cooperate with a means of the closure body to provide a snap connection between the valve carrier ring and the closure body. The radial protrusion is constituted by a flexible inwardly inclined extremity of the circumferential wall.

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: 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.

Abstract: A tamper-evident closure includes a tamper-evident strip connected with frangible connection points to a shoulder portion of a closure body before first time opening of the closure. In the closed position of a lid, a skirt portion of the lid is located behind the tamper-evident strip. The skirt portion includes locking lugs that protrude from the outer skirt surface towards the front and in the closed position of the lid engage an underside of the tamper-evident strip, such that upon a first-time opening the lid is only movable to the open position when the tamper-evident strip is permanently removed by breaking the frangible connecting points. The tamper-evident strip has bent end portions with frangible connection points that are bent towards the skirt portion, whereby a virtual straight line through these frangible connection points, seen from the front, lies behind a virtual straight line through the other frangible connection points.
