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 suck-back valve selectively actuatable for dispensing liquid in its open condition from an associated liquid storage container, and for avoiding continued presence of excess dispensed liquid about the exit orifice in the closed condition of the valve, is formed at least in part of a spring member and a pin. The spring member includes a distal web that defines a valve seat and a dispensed liquid exit orifice, a proximal web, and a plurality of flexibly elastic bands helically connecting the distal and proximal webs. The pin includes an elongated shaft having a proximal end secured to the proximal web and carrying a substantially hollow frustoconical cone at its distal end. The cone has an outer valving surface for releasable abutment with the valve seat and the shaft has a bore of predetermined cross-sectional extent defined longitudinally along and within the shaft to create a continuous fluid passageway through and along the pin. Dispensed liquid remaining proximate the exit orifice is sucked back into the liquid container through the shaft bore as the valve returns from its open to its closed condition under the return urgency of the elastic bands.

An ophthalmic dispenser and method of filling and dispensing fluid stored therein. The dispenser includes a rigid housing defining a fluid-receiving chamber, a flexible bladder receivable within the fluid-receiving chamber, a pump coupled in fluid communication with the fluid-receiving chamber, and a nozzle having a valve defining an annular, axially-extending valve seat, an outlet aperture coupled in fluid communication between the valve seat and the pump, and a flexible valve cover extending about the valve seat and forming an annular, axially-extending interface therebetween. The valve interface is connectable in fluid communication with the outlet aperture, and at least part of the valve cover is movable between (i) a normally closed position with the valve cover engaging the valve seat to close the interface and form a fluid-tight seal therebetween, and (ii) an open position with at least part of the valve cover spaced away from the valve seat in response to pumped fluid flowing through the outlet aperture at a pressure greater than a valve opening pressure to allow the passage of pressurized fluid therebetween. The rigid housing is mountable within a cartridge which, in turn, is mountable within a dispenser housing including an eyelid depressor and a trigger for simultaneously actuating the eyelid depressor and pump.

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.

The invention relates to a dispensing head for a system for dispensing a product, said head comprising a body which has a well for mounting said head on a tube for the pressurized supply of the product and a recess which is in communication with said well, said recess being provided with an abutment, around which a nozzle is mounted so as to form, at the interface thereof, a path for dispensing the product between said recess and a passage for discharging said product, said head comprising a sheath which is attached around the periphery of the abutment in order to define at least one part of the dispensing path, said sheath being capable of ensuring microbiocidal action on the product contained in said dispensing path.

Provided is a cream-type cosmetic container, which can easily discharge a highly viscous content without a separate pumping member by allowing a button part to downwardly move and then return to an original location and thus changing the internal pressure of the container body when a user pressurizes the button part, and thus can save the assembling time and the manufacturing cost.

A device for dispensing liquid including an opening for dispensing liquid, a pad for absorbing residual liquid and a removable cap including a shape in the immediate vicinity and opposite the dispensing opening, referred to as a shape for expelling residual liquid, configured to discharge the residual liquid toward the pad when the cap is mounted on the device.

A liquid contents ejection container having a nozzle blocking structure, according to an embodiment of the present invention, comprises: a container body in which liquid contents are stored; an ejection means connected to the container body so as to eject the liquid contents; a push button which is connected to the ejection means so as to operate the ejection means, and which has an ejection path formed therein; and a nozzle blocking means composed of a nozzle, which is coupled to one side of the push button and has an ejection hole, an elastic body, which is formed in the nozzle and is elastically deformed, and a nozzle valve, which opens/closes the ejection hole while moving back and forth by means of the elastic body, wherein the nozzle valve is spaced from the ejection hole so as to open the ejection hole while the elastic body is stretched outward from the inside of the nozzle, and the nozzle valve covers the ejection hole on the outer side thereof so as to close the ejection hole while the elastic body is restored.
