Abstract: A self-closing dispensing valve includes a valve head with a dispensing orifice, and a peripheral retaining flange adapted to fix the valve in a dispensing closure. The valve is manufactured by injection moulding or compression injection moulding the valve from a plastomer material. Next, the injection moulded valve is transported to an oven, in which it is brought to a temperature in a range 50-60° C., preferably a temperature of 55° C. The valve is allowed to cool, preferably to room temperature after which the dispensing orifice is cut in the valve head.

Abstract: A self-closing dispensing valve is made of plastomer or thermoplastic elastomer 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 valve head has a dome shape with a concave exterior side and a convex interior side. The connecting 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 the connector sleeve is omitted and the valve head is directly connected to the retaining flange.

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 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 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.
