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 dispensing closure for dispensing liquid, comprising an outer nozzle component (6) defining a nozzle opening (66) and a valve assembly (7) disposed in the closure upstream of the nozzle opening, the valve assembly comprising an outer valve element (3) and a generally rigid intermediate valve seat element (4) disposed inwardly of the outer valve element, the outer valve element comprising an outer valve flap (38) and the intermediate valve element (4) defining an outflow opening (451) bordered by an outer seat region (411,471), the outer valve flap (38) being movable between a closed position, in which it overlaps the outer seat region of the intermediate valve element to close the outflow opening (451) against inflow therethrough, and an open position, in which it is deflected away from the outer seat region (411,471) to open the outflow opening for outflow.

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.

A dispensing closure for a squeeze bottle comprises an outer element, an intermediate element and an inner element. The outer element (3) comprises an outwardly-deflectable diaphragm (35) surrounding an outlet opening (36). The intermediate element (5) comprises an annular seat (57) underlying the outlet opening (36) of the outer element and support structure (56) for the annular seat, with an inflow opening (552) through the annular seat (57) and an outflow opening (551) through the intermediate element around the annular seat (57). The inner element comprises a blocking portion (48; 148) and support structure (46; 146) mounting the blocking portion in the closure aligned with the annular seat. The diaphragm has an inward closed position in which the annular seat of the intermediate element engages around the outlet opening to block flow, and an outwardly-deflected position in which it allows outflow through the outflow opening and outlet opening. The blocking portion of the inner element has a closed position in which it blocks the inflow opening (552) through the annular seat, and an inwardly-deflected position to allow inflow such as venting or suck-back.

A liquid-dispensing device including a cap for protecting a liquid-dispensing opening, the protective cap being provided with a pad for absorbing residual liquid, made of an absorbent material, the absorbent pad being fastened to a support made of a more resistant material than the absorbent pad, the support being furthermore fastened in the protective cap.

A massage applicator for massaging cream-type fluids into the skin, provided with an end wall with a massage region, on which massage elevations are provided. The end wall is penetrated by at least one outlet channel for the cream-type fluid. The massage applicator is provided with suitable markings in the massage region for measuring the fluid to be used, the applicator is provided with a cover which can be blocked in an open position and/or secured in a closed position, and an assembly of two valves is used in order to secure against unintentional discharge.

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.

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.

A massage applicator for massaging cream-type fluids into the skin, provided with an end wall with a massage region, on which massage elevations are provided. The end wall is penetrated by at least one outlet channel for the cream-type fluid. The massage applicator is provided with suitable markings in the massage region for measuring the fluid to be used.

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.
