An actuating system is provided for a dispenser cartridge that can be mounted on a frame and that has a reciprocatable product-dispensing hollow stem that (A) is biased to an extended position in which the cartridge is unactuated, and (B) is moveable from the extended position to a depressed position in which the cartridge is actuated for discharging the fluent substance through the stem. The actuating system includes a plunger on the frame, and a discharge conduit located adjacent the frame to accommodate relative movement between the discharge conduit and the frame. The discharge conduit includes (A) ml inlet opening communicating with the dispenser cartridge hollow stem, (B) ml outlet opening from which the fluent substance can be dispensed, (C) a passageway between the inlet opening and outlet opening, and (D) an intermediate opening that is in communication with the passageway between the inlet opening and the outlet opening.

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, a flow conduit providing a flow path to the exit orifice, and a skirt configured to attach to a 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 normally biases the piston valve to the open position.

A system for accurately dispensing small droplets from a positive displacement pumps is actuated by a linear actuator. Preferably the linear actuator is a piezo-actuator. In a method to use the device the system pressure is stabilized before dispensing a plurality of droplets.

A spray nozzle chip comprising: a first layer provided with a first layer orifice, and a mechanically flexible nozzle layer provided with a nozzle orifice, wherein the first layer has a valve seat arranged aligned with the nozzle orifice, wherein the spray nozzle chip has a valve functionality obtained by movement of the nozzle layer relative to the valve seat due to pressure changes, and wherein the nozzle layer is arranged at a distance from the valve seat when the nozzle layer is in a default non-pressurised state, whereby a gap with a gap length (L) is formed between the nozzle layer and the valve seat, wherein the gap length (L) is smaller than a dimension of a specific bacterial type, to thereby seal against bacterial ingrowth through the nozzle orifice of the specific bacterial type.

A measurable dispenser, comprising a first vessel for containing a substance to be dispensed, a second, measurable, vessel, mounted on the first vessel, a one-way valve whereby fluid from the first vessel can be caused to move into the second vessel and retained therein virtue of the one-way valve, and wherein the second vessel is provided with one or more indicia indicating measured amounts. A child-proof locking mechanism is also disclosed.

A dispensing tip assembly includes a foodstuff additive dispenser for a pressurized foodstuff container. A tip body of the dispensing tip assembly may have low pressure zone in which fluid pressure is lower than fluid pressure upstream of the low pressure zone as flowable foodstuff from the foodstuff container flows through the internal flow passage toward an open downstream end of the tip body. The dispenser tip assembly may include one or more of duckbill valves tethered to one another, and/or a plurality of injection ports and/or structure for one-direction dispensing, and/or internal fins to couple to an actuator of the foodstuff container, and/or an anti-rotation device, and/or a collar for attaching a bulb or pod of the tip body, and/or an ergonomic and functional bulb.

A container for discharging liquid contents according to an embodiment of the present invention comprises: an inner container in which liquid contents are accommodated; an outer container surrounding the outside of the inner container; a sealing frame which blocks an open side of the outer container, is coupled with the inner container, and has an air inlet hole; an air inlet valve which is installed in the sealing frame and opens and closes the air inlet hole in response to changes in the pressure inside the outer container; a shoulder which is coupled to one side of the outer container and surrounds the sealing frame, and has a discharge passage formed therein; a nozzle which is coupled to the shoulder and has a discharge port formed therein; and a discharge valve which is installed on the shoulder and opens and closes the discharge passage by means of the discharge pressure of the liquid contents.
