A valve mechanism for a high-pressure spray can has a switching base, a first ball, and a second ball. The switching base has a first passage, a first suction port, a second passage, and a second suction port. The first passage has a first inclined inner wall surface. The first inclined inner wall surface extends obliquely toward a specific side from the top end to the bottom end of the first passage. The second passage has a second inclined inner wall surface. The second inclined inner wall surface extends obliquely toward the specific side from the bottom end to the top end of the second passage. The first ball and the second ball are respectively mounted in the first passage and the second passage and move along the first inclined inner wall surface and the second inclined inner wall surface to block the first suction port and the second suction port.

The present invention relates to a dispensing system for spraying a liquid/gas mixture, the system comprising a dispenser and a holder in which the dispenser is held, the dispenser comprising a container that is adapted for holding therein a liquid phase and a gas phase that is at a pressure of 2 bar or greater and is in direct contact with the liquid phase. The dispensing system may be used in a first orientation and a second orientation, wherein the ratio of liquid to gas in the sprayed mixture is different depending on the orientation of the system during spraying.

A discharge apparatus for an aerial vehicle is provided which is capable of mounting an aerosol container by effectively utilizing a space outside an airframe.

The discharge apparatus for an aerial vehicle, in which a content is discharged through a nozzle from an aerosol container mounted on an airframe, is characterized in that the aerosol container is mounted outside the airframe, and is arranged so that a central axis of the aerosol container is along a pitch axis of the airframe, or arranged on an extension portion such as a small wing extending from a fuselage of the airframe, an arm portion provided with a rotor blade, a leg portion for taking off and landing, or the like, with the aerosol container and the nozzle being connected to each other through a tube.

A method of assembling a tubular simulated cigarette, the method comprising providing an elongate hollow housing having an inhaling end and a refill end; inserting an outlet valve tube, a dip tube and a support from the refill end so that the support supports the proximal end of the dip tube in the housing; inserting a refill valve into the refill end and fixing it in place to form a composition reservoir with the dip tube placing the reservoir in fluid communication with an outlet orifice when the outlet valve tube is open; inserting a valve element into a recess in the side of the housing so that the valve element is positioned to selectively close the outlet valve tube; inserting a breath operated valve actuation mechanism laterally into the recess; and applying a cover to the recess.

An aerosol spray can has a can body, a valve assembly, a dip-tube assembly and a rigid tube. The valve assembly is mounted on the can body. The dip-tube assembly is connected to the valve assembly and has a head end channel-linked to the valve assembly. The dip-tube assembly has a flexible tube and a weight piece. The two ends of the flexible tube are connected to the valve assembly and the weight piece respectively. The rigid tube is sleeved around the flexible tube to constrain excessive bending of the flexible tube. The flexible tube protrudes from the rigid tube. The weight of the weight piece drives the tail end freely toward the ground. Therefore, the tail end stays submerged under a liquid product when less than a half of the liquid product is left inside the can body even when the can body is tilted or horizontal.

A molding head includes: an outer casing unit that has a top wall portion which is installed above a discharge hole and in which a plurality of shaping holes are formed, and that causes a molding surface of the top wall portion to discharge the content which has passed through the shaping holes; and an inner plate that is disposed inside the outer casing unit and defines a dispersion chamber between the inner plate and a supply surface of the top wall portion, in which a guide protrusion portion with which the content collides to be introduced to openings of the shaping holes on the molding surface side is formed on at least one of inner surfaces of the plurality of shaping holes, or in at least one of circumferential opening edge portions of the plurality of shaping holes on the supply surface side.

The present disclosure generally pertains to a medical device and more particularly, a metered-dose inhaler (“MDI”) actuator capable of a targeted delivery of fine API particles having particle diameters of about 1.1 μm or less to a portion of a patient's lungs where alveoli are located.
