An essential oil diffusion mechanism, including: a housing having an accommodation chamber; and a separator that divides the accommodation chamber into an upper chamber and a lower chamber and includes a horizontal partition plate and vertical partition plates. The horizontal partition plate defines at least one interconnecting hole. An upper surface of each vertical partition plate is spaced apart from a chamber wall of the upper chamber to form an upper interconnecting aperture. Each vertical partition plate defines an interconnecting reflux hole. A lower surface of each baffling plate is spaced apart from the horizontal partition plate to form a lower interconnecting aperture. The interconnecting hole, the upper interconnecting aperture, the lower interconnecting aperture, and the air outlet are sequentially arranged in communication to form an air outlet channel. The upper interconnecting aperture, the reflux hole, and the interconnecting hole are sequentially arranged in communication to form a reflux channel.

The invention relates to a product dispensing device configured to cooperate with a product reservoir that has product dispensing means, having a dispensing duct which is configured to dispense a product from the product dispensing means into the mouth of a user in a manner that is sealed against outside air, trigger means that trigger the dispensing of the product when the air pressure (Ai) in the dispensing duct is a predefined value greater than the pressure of the outside air (A). The invention further relates to a product administration kit having such a product dispensing device and to a product administration unit having such a product dispensing device.

The present invention provides a system, a kit and a use thereof for oral mucosa delivery of a composition. The composition may comprise at least two sub-compositions admixed right before dispensing to the oral mucosa. In one embodiment, the system is a pressurized system. In another embodiment, the admixed sub-compositions are atomized. In one embodiment, one of the sub-compositions comprise a beneficiary gas, such as oxygen. In another embodiment, one of the sub-compositions comprise a nutritional supplement, a nutraceutical composition, a pharmaceutical composition, or any combinations thereof.

An aerosol generator for an aerosol dispenser is presented where, the aerosol generator has a housing having an inlet part comprising a liquid inlet configured to guide a liquid jet (L) into the housing and an air inlet configured to guide an air flow into the housing. The housing further having an outlet part having an aerosol outlet configured to guide an aerosol (C) of liquid mixed with air out of the housing. The air inlet is configured such that at least part of the air flow entering the housing through the air inlet is obstructed at a distance from the liquid jet (L) entering the housing through the liquid inlet, thereby creating a source of turbulence in the housing to interact with droplets of the liquid jet (L) to prevent coalescence of the droplets.

Disclosed is a portable inhaler, having a rotary actuation mechanism, and comprising a follower component (104), a rotary loading device (106) and a button (112). The rotary loading device comprises a cam component (108) engaged with a cage component (110), to allow a predetermined limited rotational relative movement therebetween. The button is translatable between a central position and an extended position, and can be engaged by the cam component upon rotary movement of the rotary actuation mechanism to its primed position to translate the button to its extended position, and the button can engage the cam component to effect rotary movement of the rotary actuation mechanism to its actuated position as the button translates to its central position thereby releasing the follower component.

A system and method for dermal spraying includes a portable, hand-held dermal application device with one or more disposable cartridges that spray a dermal formulation onto the skin, the disposable cartridge having a nozzle that can be activated by placing the cartridge into the spray device.

A sealing member for sealing an atomizer against undesired leakage of liquid includes a base body and a resisting portion. The base body includes a first surface, a second surface opposite to the first surface, and an outer wall connecting the first surface with the second surface. A vent passes through the first and second surfaces. The resisting portion is disposed on the outer wall and is configured to be compressed against an inner wall of a liquid storage pipe to provide sealing and avoid leakage. An atomizer and an inhalation device are also disclosed.
