An outlet valve for a dispensing nozzle comprising a first valve component constructed and arranged to be received by the dispensing nozzle and a second valve component constructed and arranged to cooperate with the first valve component. The first valve component and the second valve component define a normally-closed flow interface.

A dispensing closure for dispensing fluid product from a squeeze container consists of an outer cap element (3) and an inner element or valve disc (4) fitting inside the cap element. Each is moulded from thermoplastics; no elastomer is used. The cap element includes an outwardly-deflectable diaphragm wall (35) around a central outlet opening (361). The inner element (4) has a peripheral mounting ring (41), a central blocking portion (48) and a set of support spokes (46) providing flow clearance between them. In a closed position the blocking portion closes the outlet opening. In an outflow condition the diaphragm wall (35) deflects outwardly to allow flow. In a recovery mode the blocking portion (48) deflects inwardly for compensation air or residual liquid product to enter the container.

A cap includes a main unit fit onto the mouth of a double-walled container, a spout cylinder provided on the main unit, an inner stopper that is provided in the main unit, and a first inner valve. The inner stopper includes a communicating part that communicates with the inside of the inner container and the inside of the spout cylinder. The first inner valve includes a first valve body that covers the communicating part. The first valve body has passage holes. The first valve body being deformed from a closing position S toward an opening position O keeps acting as a partition between the communicating part and the spout cylinder.

The device makes it possible to dispense predetermined metered quantities of liquid. It includes a sealing member that can take up a liquid release position, allowing liquid to flow out of the device, and a non-return position preventing liquid from flowing back into the device. The sealing member is provided with metering means for metering out the liquid to be dispensed.

A device includes a first part having a co-molded first support, valve cover and elastic actuator, and a second part having an injection molded second support, valve seat, and variable-volume storage chamber pre-form. The pre-form is blow molded into a flexible pouch defining the variable-volume storage chamber. The one-way valve includes a semi-annular, curvilinear, relatively rigid valve seat defining axially-extending, opposing first marginal portions, and an axially-extending first mid-portion angularly extending between the opposing first marginal portions. A flexible valve member is superimposed on the valve seat and defines axially-extending, opposing second marginal portions fixedly secured on or adjacent to respective first marginal portions of the valve seat, and an axially-extending second mid-portion angularly extending between the opposing first marginal portions and superimposed onto the first mid-portion of the valve seat. The flexible valve cover and valve seat form a normally closed axially and angularly extending valve seam therebetween.

Provided is a container including a container portion configured to form a storage space in which contents are stored, a head portion disposed at an upper side of the container portion and configured to promote discharge of the contents, which enter the head portion from the container portion, through an internal pressure change caused by a pressing portion which is formed at one side of the head portion and made of an elastic material, and a nozzle configured to discharge the contents, which enter the nozzle from the head portion, in fixed amounts.

A liquid dispensing nozzle including a liquid dispensing opening and a removable cap designed to cover the recess. The cap has an exterior envelope and an interior envelope that are coaxial, mounted mobile relative to one another in an axial direction and each have a sealing surface and able to assume a before first use storage configuration, in which the sealing surfaces of the exterior envelope and the interior envelope are in hermetically sealed contact with one another. The cap further includes a safety envelope mounted mobile relative to the exterior envelope between a configuration for unscrewing the cap when a bearing force exerted on the safety envelope has an intensity greater than a predetermined threshold, and a safety configuration when the bearing force has an intensity less than a predetermined threshold or when no bearing force is exerted on the safety envelope.
