The invention relates to an electronic smoking device (100) with an atomizer/liquid reservoir portion (114) and to an atomizer/liquid reservoir portion (114). In order to facilitate refilling a liquid reservoir (134) of the atomizer/liquid reservoir portion (114), the atomizer/liquid reservoir portion (114) comprises a docking valve (146) for docking a source of liquid (148) to be stored in the liquid reservoir (134), and a liquid duct (156) that is adapted to receive liquid (172) from the docking valve (146) and that opens into the refillable liquid reservoir (134) at a predetermined distance (A) to the docking valve (146).

Vent assemblies for reservoirs and other closed systems. The vent assemblies include one or more apertures in a wall of the reservoir. A closure member is retained on the external surface of the reservoir by a closure member retainer and includes a first component and a second component, the second component is relatively conformable compared to the first component. The second component is positioned between the first component and the wall of the reservoir. A sealing surface is located on either the first component or the second component, where the sealing surface closes the aperture when the closure member is in an unvented position, and the sealing surface does not close the aperture when the closure member is in a vented position.

A spray dispenser is provided, the spray dispenser comprising a container for holding a liquid to be dispensed and a dispensing assembly for extracting liquid from said container, the dispensing assembly comprising a pressure-relief valve for release of excessive pressure in the container and a filter arranged to permit egress of gas through the filter, inhibit egress of liquid from the container and to inhibit ingress of contaminants into the container through the pressure relief valve. A dispensing assembly for use is a spray dispenser is also provided.

A refillable fluid product dispenser having a fluid product reservoir defining a neck and a filling port; a dispensing member, such as a pump, mounted on the neck of the fluid product reservoir for extracting the fluid product; a filling valve; a chamber separating the filling port from the filling valve. The chamber has a retention mechanism for retaining the fluid product inside the chamber.

Disclosed is a liquid dispenser, including a pumping structure and a pressure-accumulation ejecting structure which cooperate for use, wherein the pumping structure includes a main frame, a liquid storage cavity and a piston rod, the liquid storage cavity is built into the main frame, and the lower end of the liquid storage cavity is provided with a liquid inlet and a liquid outlet which can be opened and closed; the piston rod can move upward and downward along the liquid storage cavity under the action of a driving member, when the piston rod moves downward, only the liquid outlet is in an open state, and when the piston rod moves upward, only the liquid inlet is in an open state. The liquid dispenser of the present disclosure is simple to assemble, and the service life of the liquid dispenser is prolonged while improving the stability of assembly of parts.

A ventilation fluid supply cup has a container arranged with a vent hole, the vent hole is closed by a valve, the valve includes a valve housing arranged at a corresponding position of the container, the valve housing is arranged with a closing element, the valve housing includes at least one hollow column protruding around a periphery of the vent hole, the hollow column is arranged with at least one vent opening, the closing element is arranged with a vent position matched with the vent opening, the closing element is capable of rotating along a circumferential direction of the valve housing; the vent opening and the vent position are connected to make pressure between an inside of the container and an external environment balanced; the vent opening and the vent position are in a disconnected state to close the vent opening by a side wall of the closing element.

A frame for a trigger head of a dispensing device for a liquid product has a frame base, a cylindrical pressure chamber, an intake duct, an outlet duct, a dispensing duct, and a shoulder consisting of a shoulder wall protruding from a rear zone of the frame base to form a backing for a hand of a user gripping the trigger head while dispensing the liquid product. The shoulder has a rear coupling for a shell of the trigger head.
