A liquid dispensing device includes a multifunction membrane valve that, in addition to allowing the dispensing of drops with a drop-check mechanism, ensures and isolates the passage of the air to be filtered so that it does not contaminate the liquid in the interior of the dispensing device; it has a reduced number of parts; it facilitates proper assembly by counter pressure, without the need for threads or complex coupling elements; it avoids the need for rotational alignment when assembling the parts, among other advantages.

A massage applicator for massaging cream-type fluids into the skin, provided with an end wall with a massage region, on which massage elevations are provided. The end wall is penetrated by at least one outlet channel for the cream-type fluid. The massage applicator is provided with suitable markings in the massage region for measuring the fluid to be used, the applicator is provided with a cover which can be blocked in an open position and/or secured in a closed position, and an assembly of two valves is used in order to secure against unintentional discharge.

An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

A dispensing system, a flexible bag or pouch for use therewith, and methods for filling a dispensing bottle with a flowable product and dispensing the same are disclosed. The system includes a flexible bag and a dispensing bottle. The flowable product is located in the bag. The bag includes a first end and a second end. The bottle includes an interior chamber, a squeezable sidewall surrounding the chamber and a bottom cap including a dispensing valve. The bag is disposed in the chamber with the second end opened to form an open mouth, whereupon the flowable product is in communication with the dispensing valve. Squeezing of the bottle's sidewall applies pressure to the flowable product to cause it to be dispensed out of the bottle through dispensing valve.

A package includes a container and a closure arranged to close an opening into an interior region formed in the container. The closure includes a dispensing cap formed to include a body adapted to be coupled to a neck of the container and a product-discharge spout coupled to the body to discharge product stored in the container that passes from the interior region of the container into a discharge passageway formed in the product-discharge spout.

A two-piece dispensing closure for dispensing essential oils includes an insert received into a container opening and a closure body including a dispensing spout and a hinged cap. The cap is connected to the closure body by a living hinge to allow the user to selectively open and close the container. A tamper-evident tear strip is integrally formed with the closure body. The insert and the closure body including mating helical ramps which cooperate to insure that the insert remains installed within the container neck when the closure body is removed after purchase.

The disclosure relates to a device for making charged nanoparticles, the device includes: an atomizer configured to atomize a solution into micro-scaled droplets; a first electrode and a second electrode substantially parallel with and spaced from each other, a power supply configured to apply a voltage between the first electrode and the second electrode, at least one first through-hole is defined on the first electrode and at least one second through-hole is defined on the second electrode to allow the micro-scaled droplets to pass through.

The disclosure relates to a method for making charged nanoparticles, the method includes: providing a solution with a first solute; atomizing the solution into micro-scaled droplets; providing a charged electrode with at least one through-hole, a negative or positive electric potential is applied to the electrode; allowing the micro-scaled droplets to pass through the at least one through-hole.

The present invention is a device for dispensing a mixture of a first fluid and a second fluid, suited to be applied to a container holding said fluids. The device comprises a mixing chamber for these fluids, a suction tube suited to draw the second fluid in order to convey it into the mixing chamber and a tank-chamber arranged between the suction tube and the mixing chamber. The device also deviates a quantity of the first fluid coming from the suction tube towards the tank-chamber.

An unfilled liquid reservoir for use as part of a dispenser for dispensing pharmaceutical or cosmetic liquids, including an outer housing for placing on a dispensing head of the dispenser and a flexible bag arranged within the outer housing for receiving liquid before the dispensing process. The bag has an opening for removing the liquid, and an intermediate region between the outer housing and the bag is connected to a surrounding area by a ventilation opening which passes through a wall of the outer housing. The flexible bag is provided in a stowed storage state in which the inner volume of the bag is maximally 10% of the maximum inner volume of the bag within the outer housing.
