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.

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.

A liquid dispenser for cosmetic liquids having a liquid reservoir and an applicator. An outlet channel connects the reservoir to the applicator, the outlet channel being formed either valveless or with an outlet valve. The liquid dispenser has a pressure generating device which pressurizes liquid in the reservoir for conveyance through the outlet channel to the applicator. The pressure generating device has an air pumping device which feeds and an actuating pressure chamber. The actuating pressure chamber adjoins, and is separated from, the reservoir by a displaceable wall so that an overpressure in the actuating pressure chamber leads to an overpressure in the reservoir. The air pumping device has manual actuator, allowing air to be pumped into the actuating pressure chamber by the actuator, so that the overpressure in the actuating pressure chamber and in the reservoir rises sufficiently to convey liquid from the reservoir to the applicator.

A squeeze container capable of preventing a clogging caused by a powdery content is provided. The squeeze container capable of discharging a powdery content to an outside of the squeeze container, the squeeze container having two tubes suspended down to the inside of a container body to serve as through holes of the powdery content, the tip of one tube of the two tubes is fixed to one hole formed on an upper surface of the cylindrical body, the tip of the other tube passes through the other hole formed on the upper surface of the cylindrical body and extends to an internal space of the cylindrical body, and a gap is formed between a bottom of the container body and the opening of the cylindrical body so that the powdery content can enter into the internal space of the cylindrical body.
