A combined lid/valve device including a lid, for a pressurised product dispensing container, and a valve mechanism, in which the lid is provided with a so-called upper face and a so-called lower face, in which the lower face of the lid includes a base provided with a skirt for receiving the neck of a pocket containing the product to be dispensed, the base forming a housing for the valve mechanism consisting of a dispensing tube and a sealing gasket, the sealing gasket mounted on the dispensing tube snap-fitting into a through-hole between the upper face and lower face of the lid and allowing an outlet end of the dispensing tube to project beyond the upper face of the lid.

A tire sealant dispenser matches with an air compressor and contains a body in which chemical fluid (such as tire sealant) is filled, a cap connected on an opening of the body, a drive element configured to urge a punch element to pierce a film, such that an air conduit is in communication with a sealant conduit, pressurized air flows into the body via the air conduit from the air compressor, and the chemical fluid flows out of the sealant conduit.

An aerosol product diffuser assembly comprises: a diffuser block (1) comprising an annular casing (2) inside which a cam actuator (3) is mounted axially mobile, a control lever (10) provided with a planar body (12) making it possible to control the diffusion of the aerosol liquid said cam actuator (3) comprising: (i) an axially mobile cam follower plate (4); (ii) an aerosol bottle nozzle housing (5), arranged on the cam follower plate (4); (iii) a duct (6a) connected to the nozzle housing and enabling the liquid to diffuse to a discharge point of the aerosol liquid, the control lever (10) being pivotably mounted on the annular casing (2), and the cam actuator (3) being able to be pushed axially towards the aerosol bottle by at least one pivoting cam (15).

An 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, to make use of an adjustable straw, the diverter valve is rotated to engage a straw spray passage of the diverter valve in fluid communication with an adjustable rotary spray tip and engaged straw. By rotating the adjustable rotary spray tip to an aligned position, the tip substantially blocks the straw spray passage to provide a drip mode, where drops of fluid exit the straw. A flexible tip may optionally be provided on the straw to enable bending and retention of the flexible tip to a desired position.

A syringe propellable by a propellant that boils at a predetermined temperature, the syringe comprising a barrel having an outlet at a front end, a stopper axially moveable in the barrel, and a third chamber for containing propellant. The stopper defines and separates a first chamber and a second chamber, the first chamber being axially forwards of the stopper and being configured for containing a medicament, and the second chamber being axially rearwards of the stopper and being configured to receive propellant for acting on the stopper to move the stopper axially forwardly in the barrel to expel medicament through the outlet upon actuation of the syringe. The syringe is configured such that, in use, upon actuation of the syringe, liquid propellant is released from the third chamber and boils outside of the third chamber at or above the predetermined temperature to provide an increasing vapor pressure in the second chamber that causes the stopper to move axially forwardly and begin to expel medicament from the first chamber through the outlet. During forward axial movement of the stopper in the barrel, propellant vents away from the second chamber through a vent hole.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

The present disclosure relate to an actuator assembly for an aerosol can. The assembly includes a body attachable to a can and a disc provided with two opposing levers. The disc is hinged to the body and generally overlies a valve provided on the aerosol can. When either lever is depressed, a valve socket on the bottom of the disc engages the valve of the aerosol can to discharge pressurized liquid through a port formed through the disc. One of the levers is provided with a catching member that engages and selectively locks onto a latch provided on the body so that the lever is captured in a depressed position to cause the continuous discharge of liquid from the can. The captured lever can be released to discontinue discharge of liquid by pressing the other lever.
