A spray control apparatus for aerosol cans has a can coupling cap with a segmented and discontinuous aerosol can engaging ring. The cap top lip has a locking ledge having a bearing surface facing away from the can engaging ring, a cam track having a bearing surface facing toward the can engaging ring, and a guide slot therebetween. A plurality of generally planar reinforcing ribs radiate inwardly from the cap side wall. An actuator is concentrically within the cap, and has at least one cam protruding radially into the cap top lip. The cam engages the locking ledge bearing surface in a first rotary position and is thereby blocked from axial movement, and engages the cam track bearing surface in a second rotary position and is thereby driven axially toward the can engaging ring, and passes though the guide slot when rotated between the first and second rotary positions.

A safety lid for an aerosol container, including a dome surrounding at least part of a diffuser device and provided with a movable component, which can move between a first position for preventing the operation of the diffuser device, a second position for intermittently activating the diffuser device and a third position for emptying the container. The movable component including means for permanently activating the diffuser device in the third position.

A device for charging a primary fluid system, such as an air-conditioning or cooling system, closed and at a first pressure (P1), with a secondary fluid, comprises a dispensing cylinder of the secondary fluid, said cylinder containing the secondary fluid and a propellant fluid having a second pressure (P2) greater than said first pressure. Said cylinder further comprising a filler valve operable to allow/block the exit at least of the secondary fluid from the cylinder. A connection hood is partially superposed over the dispensing cylinder, fitted with connections means suitable for fluidically connecting said filler valve directly to said primary fluid system or to a connection pipe to said system.

A device for dispensing pressurized air and/or tire sealant from a pressurized can. The device comprising a cap body, a depressor button with a lock clip, and a hose positioned within the cap body attached to the pressurized can. The lock clip locks the depressor button in the compressed position for ease during use, while a shield element keeps the depressor button in the non-compressed position for safety during non-use. The hose provides an extension to attach to a tire stem valve, while being stored and attached to the cap body of the device.

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.

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.
