A discharge device is provided with a pressurized product filling and sealing the concentrate and the pressurizing agent P inside the container, and a discharge member discharging the concentrate by breaking through the pressurized product. The discharge member is provided with a valve which becomes a discharge passage of the concentrate, and a cap which covers the valve and is detachably mounted to the pressurized product. The discharge device is provided with a suppressing means (a maintaining mechanism, a movable lid, pressing to the bottom of the recessed part of the projecting part, a part releasing mechanism, a ratchet mechanism, a thin part and a plurality of coupling parts) for suppressing the leakage of the concentrate caused by removing the valve.

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 dispenser for aerosol containers includes: a nozzle; and a cover including an operating portion. One of the operating portion and the nozzle includes a sliding portion capable of depressing the nozzle to a predetermined depression position together with a plurality of stems while sliding on a slid portion provided at an other one of the operating portion and the nozzle to a termination, with a depression operation on the operating portion. A vibration generation portion that generates vibration as a result of entry of the sliding portion is provided at the termination of the slid portion.

An adjustable actuator for a spray can. The actuator includes a housing for attachment to an aerosol can covering a stem valve. A finger operating button structure is engaged with the housing for engaging the stem valve. A rotary two-way diverter valve is supported within the housing and rotatably engaged with the finger operating button structure. In a spray position/straw down, the two-way diverter valve directs spray through a first direct spray nozzle. In a second straw position/straw up, the diverter valve is rotated to engage a straw spray passage of the diverter valve in fluid communication with a spray tip and engaged straw. A sliding tab member engaged between and on the housing and button structure is used to adjust the desired amount of fluid flow.

An overcap assembly configured to attach to a container. The overcap assembly includes a body, an actuator, a first nozzle, and a second nozzle. The actuator is integrally attached with the body and defines a longitudinal axis. The actuator further comprises a fluid passageway that extends therein. The first nozzle and the second nozzle extend laterally from the actuator, and the first nozzle and the second nozzle define a portion of the fluid passageway. The first nozzle comprises a first angled exit aperture and the second nozzle comprises a second angled exit aperture. The first nozzle and the second nozzle each comprises an inner cylindrical wall and an outer cylindrical wall surrounding and spaced apart from the inner cylindrical wall. The first angled exit aperture and the second angled exit aperture are non-parallel to the longitudinal axis.

Heads for an aerosol container are disclosed. The head comprises a handle body having a base configured to be coupled to the aerosol container, an outlet, a flexible tube housed within the handle body. The flexible tube is configured to provide fluid communication between the container exit of the aerosol container and the outlet. And the head further comprises an elastically deformable actuator having a lever arm, and a coupling portion integrally formed with the lever arm and configured to be mounted around the flexible tube, wherein the coupling portion is further configured such that when the lever arm is deformed by a user, the coupling portion actuates on the valve body of the aerosol container. Aerosol containers having such heads and kits for treatments skin lesions are also disclosed.

An actuator for a valve is lockable with a tubular member to maintain the valve in either an actuated position or in an unactuated position. Locked in the actuated position, degassing can occur. Locked in the unactuated position, inadvertently dispensing of product is prevented.

An aerosol sprayer may be connected to an aerosol container to form an aerosol delivery system. The aerosol sprayer includes a base secured to the container, a cap secured to the base, a pivoting trigger and a sliding nozzle body with an integrated nozzle/manifold which is slidably movable relative to the trigger between an extended operable position and a retracted, locked position. The nozzle includes flexible articulating wall structures adjacent to the manifold to accommodate movement of the nozzle body. The nozzle and trigger have interfitting locking structures to prevent actuation of the trigger when the nozzle is in the retracted locked position.

A pressurizable fluid container apparatus, system and method of use.

An actuator cap (1; 50) for a fluid spray dispenser comprises a second body part (2) and a first body part (3). The first body part (3) is adapted for connection to a container for the fluid to be dispensed and incorporates a spray channel arrangement (4). The second body part (2) incorporates an actuator button (5) and is rotatable with respect to the first body part (3) from a first position in which the actuator button (5) is non-elevated into a second position in which the actuator button (5) is elevated and capable of depression to cause depression of a part (16) of the spray channel arrangement (4). The actuator button (4) defines a first cam profile (20) along which a first cam follower (22) defined by the first body part (3) travels to cause elevation or retraction of the actuator button (5) when the second body part (3) is rotated. The actuator button (5) also defines a second cam profile (23) that bears against said part (21) of the spray channel arrangement (4) such that when the actuator button (5) is in its elevated position and depressed the actuator button (5) depresses the second cam profile (23) and in turn depresses the part (21) of the spray channel arrangement (4) relative to the first body part (3) to dispense fluid from the container when in use. Preferably, the first and second body parts (3, 2) are individual, integrally moulded components that are snap-fitted together to assemble the actuator cap (1; 50).
