A discharge pump (2) includes a stationary suction part (A) which includes a cylinder (A1) having a first check valve (V1) at a lower part thereof, and a mounting member (A3) to be mounted on a neck part of a container body, and an actuating member (B) which includes a discharge head (B4), a stem (B2), a piston guide (B1), and an annular piston (B3), a second check valve (V2) being formed between a lower end part of the annular piston and a lower part of the piston guide, and in a fitting part between the stem and the piston guide, an engaging unit (E) which is configured to restrict the stem and the piston guide from idling each other when screwing of the actuating member to the stationary suction part is released and the actuating member is raised from the stationary suction part is provided.

A two-component piston for a cartridge includes a piston cover and a piston body. The piston cover has a radially extending attachment portion, a rear side and a front side. The piston body includes a front side and a rear side. The rear side of the piston cover is arranged adjacent to at least a part of the front side of the piston body and includes a valve member configured and arranged to be received within the piston body and to extend into the piston body towards the rear side of the piston body. The piston cover moves relative to the piston body upon actuation of the valve member, and the piston cover is non-releasably connected to the piston body by a part of the piston body being overmolded to the radially extending portion of the attachment portion of the piston cover.

The present invention relates to a system and assembly for refilling a reservoir with liquid dispensed from a dispenser, in particular, but not exclusively, to a system and assembly for the substantially leak-free refilling of the reservoir of a smoking-substitute device with a liquid comprising nicotine from a refill dispenser. The assembly is configured to provide a gas communication pathway through the assembly and physically separate from the liquid communication pathway for venting gas from an end of the assembly proximal the first aperture to an exterior of the assembly responsive to the movement of the assembly to the secured and open configuration, the assembly configured to close the gas communication pathway in the unsecured and closed configuration.

A liquid dispenser, having a large ring, a connecting cover, and a hollow pump frame, the pump frame is movably clamped to the interior of the large ring, the top of the pump frame extends to the outer side of the top of the large circle, a bottom protruding portion of the connecting cover extends into a top groove of the pump frame so as to be movably clamped thereto, a first air outlet is provided on both sides of the bottom of the connecting cover, and a second air outlet in communication with the first air outlet is provided to penetrate through the pump frame. The first air outlet, the second air outlet, the first liquid outlet, and the second liquid outlet can be opened and closed by rotating the connecting cover to change a position relationship between the connecting cover and the pump frame

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 cosmetic vessel may include a vessel body including an inner case configured to accommodate cosmetics and having an inlet, and an outer case configured to accommodate the inner case therein and having an opening in a top thereof, a cap part coupled to the open top of the outer case, a discharge means coupled to the inlet and configured to discharge the cosmetics to an outside through a suction pipe extending to a bottom surface of the inner case, and a discharge part moving downwards to operate the discharge means and configured to transmit the cosmetics discharged from the discharge means to the outside.

Fluid product reservoir having a neck defining an opening, the neck having an upper annular edge defining an outer ridge and an inner ridge, the opening being defined by an inner wall connected to the upper annular edge by the inner ridge. At least one cutout is provided at the upper annular edge, this cutout extending on the inner wall, interrupting the inner ridge, but does not extend as far as the outer ridge, such that the upper annular edge is continuous over its entire periphery, including at the cutout, this cutout further forming a base defining a ridge with the inner wall of the opening.

A delivery tube and cap are configured to be connected to a container that houses fluid to be delivered to a nasal cavity. The delivery tube includes an inner cannula that is positioned within an outer cannula. Each of the cannulas includes an outlet. The delivery tube and cap are configured to provide relative axial movement between the cannulas. The cannulas are positionable between a first axial position that aligns the outlets to deliver the fluid out of the device in a lateral direction and a second axial position that misaligns the outlets to impede the fluid from being delivered out of the device in the lateral direction.

This application relates to a fluid dispenser. In one aspect, the dispenser includes a body including an opening and an accommodating space for accommodating fluid, a lid for closing the opening, a pressing unit disposed on a side of the body, and a discharge unit disposed on the side at a position diagonally higher than the pressing unit and configured to discharge a predetermined amount of the fluid from the accommodating space when a pressure is applied to the pressing unit. The dispenser may also include a pump mechanism configured to pump the predetermined amount of the fluid from the accommodating space to the discharge unit when the pressure is applied to the pressing unit, and an air intake formed on a part of the lid and configured to flow air into the accommodating space when the predetermined amount of the fluid is discharged from the accommodating space.

A piston pump for dispensing fluid from a reservoir, an improved vacuum relief arrangement in which a passageway for flow of air from the atmosphere into the reservoir is provided at least in part through a piston-forming element of the piston pump.
