Provided is a medication dispenser configured to discharge a liquid state medication stored therein by a pumping operation in a predetermined amount in a drop state and prevent a noise occurrence during medication discharge, and having a bacteria infiltration prevention function, wherein a flow path member and a second check valve are mounted in a liner, the second check valve is composed of a hemispherical cylinder mounted in an elevation space of the liner, having an open upper part, and of which a diameter decreases toward a lower end and includes a variable part in which the hemispherical cylinder is vertically variable and an opening and closing protrusion configured to perform supply and blocking of a flow path.

A trigger-type ejector includes: a pressure storage chamber formed in a nozzle head and communicating with a flow path through a communication hole; a pressure storage plunger including a large-diameter pressure receiving portion opposite a small-diameter pressure receiving portion and being movable between a close position where an ejection hole is closed and an open position where the ejection hole is opened; and a biasing member disposed in the pressure storage chamber and biasing the pressure storage plunger toward the close position, the trigger-type ejector being configured such that, when a pressure of a liquid in the pressure storage chamber becomes equal to or greater than a predetermined value, the pressure storage plunger moves from the close position to the open position against a biasing force of the biasing member and thus a liquid in the pressure storage chamber is ejected from the ejection hole to the outside.

A dispensing closure for dispensing a flowable product from a squeeze-type product container includes a closure body having an upper deck, an exit orifice, and a skirt configured to attach to the product container. A measuring reservoir is received in engagement with a lower surface of the upper deck. The measuring reservoir is filled with a measured dose of flowable product through flow ports when the container is inverted. A piston valve is slidably movable within the measuring reservoir between an open position and a closed position. The piston valve is movable from the open position to the closed position to dispense the measured dose of product responsive to pressure within the container induced by squeezing.

Dispenser systems, dispensers, and repositories can add a fragrance to an unscented liquid beauty preparation. The dispenser system includes a dispenser having a cavity for retaining at least a first liquid, and a repository configured for removably attaching to the dispenser, the repository having a reservoir for retaining at least a second liquid. The dispenser is coupled with a pump assembly including at least one pump for drawing the at least a first liquid and the at least a second liquid into a mixing chamber. The mixing chamber is coupled with an actuator in such a manner that when the actuator is pressed down by an external force, the mixing chamber communicates with the pump to suction the first and second liquids into the mixing chamber to form a liquid mixture for dispensing through a nozzle.

What is proposed is a nasal dispenser (10) for the nasal application of liquids in atomized form, in particular for children.

The nasal dispenser (10) has a nasal applicator (40) which is for dispensing the liquid and is formed by an outer component and an inner component, which together define a vortex chamber and at least one inlet channel into the vortex chamber.

In the case of components that are stationary in relation to one another, especially tapered inlet channels (96) for generating a high liquid velocity in the vortex chamber (98) are proposed. The cross-sectional area of the inlet channel (96), that is aligned transversely to the flow direction (4) in the inlet channel, at its narrowest point or the sum of the cross-sectional areas of the inlet channels, that are aligned transversely to the flow direction (4) in the inlet channels (96), at their respective narrowest points is at most 0.05 mm.sup.2.

In the case of a design in which the inner component (60) is arranged movably in the outer component (50), in particular for the purpose of obtaining a valve function, it is conversely proposed to design the outlet opening (54) with a narrowest cross section of at most 0.05 mm.sup.2.

Embodiments of the invention relate to dosing dispensers and in particular to dosing dispensers that may be operated using one hand by raising and filling a dosing chamber followed by lowering and dispersing a product from the dosing chamber and wherein the dose may be selected or adjusted and a user may visually confirm that the proper dose is being loaded and delivered by the dispenser.

The present invention relates to a pump head that enables a metered dispensing of fluids. The present invention also relates to a metering apparatus that can, for example, be configured as a squeeze bottle, wherein the metering apparatus comprises a pump head in accordance with the invention.

A trigger-type liquid ejector includes: an ejector main body; and nozzle member provided with an ejection hole. The ejector main body includes: a vertical supply pipe for sucking-up liquid; an ejection barrel communicating with the inside of the vertical supply pipe; and a trigger mechanism including a trigger, the trigger being arranged to be movable rearward in state of receiving forward force, and the trigger mechanism being lead liquid from the vertical supply pipe into the ejection barrel in accordance with rearward movement of the trigger and to eject the liquid from the ejection barrel. The nozzle member is provided with: a cylinder communicating with the inside of the ejection barrel through a supply hole; a plunger accommodated in the cylinder to be movable rearward in a state of receiving forward force; and a communication hole allowing the inside of the cylinder and ejection hole to communicate with each other.

The present invention relates to a pump head with a specially configured elastic valve which enables secure closure of the pump head. It is ensured by the valve that complete emptying and, at the same time, secure closing of the pump head is ensured so that no residues of fluid to be metered remain in the storage state of the pump head. In addition, the present invention relates to a metering device which can be configured for example as squeeze bottle, as non-airless system or as airless system, the metering device comprising a pump head according to the invention.

A discharging device for the discharge of liquid media is specified, with a pump chamber that comprises an inlet opening and an outlet opening, and with a piston that is displaceable in the pump chamber. The object is to be able to dispense a medium with high accuracy using the discharging device. For this purpose, the piston comprises a projection which enters the inlet opening after a predetermined stroke of the piston.
