The present invention relates to fluid dispensing devices for use in dispensing different liquids (e.g., bleach and bleach activator) from a bottle having first and second compartments. To minimize the presence of mixed composition residually present within the fluid dispensing device, it may be helpful to delay mixing. Separate dip tubes may be provided to pull liquid from the separate compartments, each with its own separate pump. Each pump may deliver the separate compositions to a spray nozzle of the device through separate delivery tubes (e.g., from the pumps to the nozzle). In other embodiments, a single delivery tube, and/or a single pump may be provided, e.g., where the volume of mixed composition that may be present in such pump and/or delivery tube may be sufficiently small so as to still provide overall desired efficacy characteristics. Dual delivery tube configurations may eliminate any need to prime the device by spraying out old, residual mixed composition.

A fluid container spray device having a trigger lock mechanism with trigger tabs extending outwardly from the trigger and cleats extending inwardly from a moveable shroud. The cleats obstruct the tabs when the shroud is in a trigger lock position. A lever extending from beneath the shroud can be depressed, thereby moving the shroud from the trigger lock position to a trigger release position. The movement of the shroud to the trigger release position moves the connected cleats from their obstructive position to a position out of the trigger tabs' path of movement, thereby permitting use of the trigger to pump fluid from the container. The shroud is biased toward the trigger lock position. Thus, release of the container by the user restores the locked configuration, thereby preventing use by children. 1.

A pump mechanism for a spray dispenser, comprising a piston assembly movable with respect to a housing between charged and initial positions. The piston assembly comprises liquid and gas seals, being movable boundaries of respective chambers whose volume is determined by the position of the seal relative to the housing. When the piston assembly moves toward the charged position, the volume of the liquid chamber increases to draw liquid into the liquid chamber and the changing volume of the gas chamber changes the pressure of gas in that chamber from its pressure when the piston assembly was in the initial position. This biases the piston assembly to return from the charged position toward the initial position, that return movement of the piston assembly pressurising the liquid in the liquid chamber for dispensing. 2. The pump mechanism of claim 1 , wherein:when the piston assembly moves from the initial position to the charged position, the volume of the sealed gas chamber is decreased and the internal pressure of the gas is increased; orwhen the piston assembly moves from the charged position to the initial position, the volume of the sealed gas chamber is increased and the internal pressure of the gas is decreased.3.

SPRAYER DEVICE WITH AEROSOL FUNCTIONALITY ("FLAIROSOL")

Автор: Haleva Aaron S., Hurkmans Petrus Lambertus Wilhelmus, Maas Wilhelmus Johannes Joseph
Принадлежит:

In exemplary embodiments of the present invention, Flair® based aerosol-type devices can be provided. Such devices utilize a combination of Flair® technology, pre-compression valves and aerosol like pressurization of the dispensed liquid. Such a dispensing device has a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring. The device further has a piston and a piston chamber which draws liquid from a reservoir and fills the pressure chamber with that liquid as a user operates the trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve. In a dispensing head a valve is provided to regulate the strength of the flow and preclude leakage. Once the liquid is sufficiently pressurized, it can be dispensed by a user opening an activation valve, such as by pressing on an activation button, and spray can be abruptly stopped by a user ceasing to push on such button. Or, for example, in alternate embodiments without an activation button, once the liquid is sufficiently pressurized, continuous spray occurs until the pressure chamber is emptied. By repeatedly pumping the trigger before the pressure chamber is fully emptied, continuous spray can be achieved. By designing the input volume to be amply greater than the volume of the pressure chamber, continuous spray with fewer pumping strokes can be implemented. 126-. (canceled)27. A method of spraying a liquid , comprising:pressurizing the liquid in a pressure chamber above a certain minimum pressure with an outlet valve locked in a closed position;releasing a valve locking mechanism,wherein said pressure chamber is provided within an inner container that is surrounded by an outer container, andwherein a pressurizing medium can flow between the inner bottle and the outer bottle.28.
