A valve gasket for a metering valve of a fluid dispenser, said gasket being made of an elastomer material that is self-lubricating.

The invention relates a metering device for fluids from a containment volume. The metering device is a means to dispense metered volumes of fluids such as detergents, medicaments, lotions and the like. The invention further provides a container for fluid material to be dispensed in metered doses.

An external metering valve disposed on a gas fuel tank including an outlet rod is provided. The outlet rod includes an outlet orifice at a front end thereof. The external metering valve includes a metering valve and a gas guiding member. The metering valve includes a metering chamber. The gas guiding member includes a communication pipe, a blocking portion on the communication pipe, a discharging channel and an inlet orifice. The gas guiding member has a sealing outlet position and a metering outlet position. At the sealing outlet position, the outlet orifice outputs a gas and stores the gas in the metering chamber. At the metering outlet position, the blocking portion seals the outlet orifice through an airtight ring, and outputs the gas stored in the metering chamber through the inlet orifice and the discharging channel.

A certain amount of contents is easily sprayed by one pressing operation. A metered spray unit 10 being mounted on a stem 23 of a valve 22 that is provided on the upper portion of a container body 21, configured to spray a certain amount of contents in a container body 21, includes an outer cylinder 30 which is provided with a stem insertion hole 30a into which the tip of the stem 23 is inserted and the inner wall thereof is fixed to the stem, a metering chamber 35 connected to the stem insertion hole 30a, the metering chamber being an internal space having a predetermined capacity, connected to the stem insertion hole 30a, and an spray port 33 communicating with the metering chamber 35, a plug member 40 that is inserted from the inside of the metering chamber 35 into the spray port 33 for blocking the spray port 33, a push button 51, an elastic member 60 for supporting the push button 51 on the outer cylinder 30, and a shaft member 50 connected to the push button 51. The elastic member 60 has an amount of displacement due to the pressing force applied to the push button 51, being smaller than the amount of displacement when applying the same pressing force to the spring for urging the stem 23 within the valve 22.

A device suitable for dispensing a liquid substance, such as an ophthalmological substance, including a container; a dispenser for dispensing the substance and which includes a piston element, loaded by the pressure of the pressurized substance so as to adopt a standby position by default that prevents the preloading chamber from being flooded by a dose of the substance; and a valve element capable of enabling a connection between the preloading chamber and the outside. The device has an actuation mechanism that sequentially compresses a volume of air used for moving the piston element from the standby position thereof, allowing a dose of the substance to flood the preloading chamber to subsequently mechanically actuate the valve element and simultaneously enable the connection to the outside of the preloading chamber as well as of the volume of air previously used for moving the piston element from the standby position thereof.
