A fluid dispensing apparatus may be used to dispense a paint fluid from a paint container that is under pressure and that has a pierceable membrane. The fluid dispensing apparatus may include a valve body having a bore, an adaptor having a bore and a piercing member, and a nozzle having a bore. The fluid dispensing apparatus may be operable to pierce the pierceable membrane to communicate the paint within the paint container with the adaptor bore and with the valve body bore. The nozzle may be operable to permit the paint to flow under the pressure out of the paint container, through the adaptor bore, through the valve body bore and through the nozzle bore to ambient.

An apparatus, method, and system that uses a lever action hand grip that can include an adjustable receiver for a variety of diameters, form factors, and other variables for different containers of liquids or aerosols that are desired to be dispensed. A linkage connects the lever action hand-grip to a working end. The working end moves in arcuate fashion in response to pivoting of the lever. The proportional working end motion path can serve to both push down an aerosol spray head to dispense, or laterally push or pump other types of dispensing heads. Optionally, the linkage can have at least one, and sometimes two or three, different adjustments for such things as size and location of a dispensing head for a variety of dispensing containers and types, range of motion, type of interface at the working end, and specifically what type of working end relative to a dispensing head of a container or bottle.

A device and method for marking indicia on terrestrial surfaces implemented in topographical surveying comprises is described; the device includes: a support element connectable to topographic surveying instrument, a container holder and paint container; an actuator; at least one nozzle configured to reversibly assume: a divergent configuration and convergent configuration; at least one driving mechanism, for driving the nozzle between the divergent configuration and convergent configurations and an outlet to dispense the paint on the terrestrial surface; the method includes: selecting a point of interest on a terrestrial surface; positioning the pointed tip; determining geographical coordinates; activating the actuator, dispensing the paint form the outlet; altering the configuration of the nozzle between the divergent and convergent configuration.

A correctional paint wand used to mark lines on pavement, turf, concrete, and other surfaces. It has a rotatable sleeve on the lower end of an elongated handle, with the sleeve having at least two aerosol paint can holders each sized for containing one inverted paint can. At least one can applies distinguishable marking paint, and at least one can applies correctional paint visually covering erroneously applied markings, with the sleeve rotated to place the needed paint can in a dispensing position. A wheel on the lower end of the wand may aid its movement over the surface targeted for marking. The error correcting paint may be green for grass or artificial turf, brown for exposed ground, light gray or off-white for cement, and black for asphalt, or other colors appropriate to the intended application. Contemplated applications include, but are not limited to, use by landscaping designers and utility companies.

A device that can hold at least two cans of spray paint or chalk, thus enabling marking with different colors using a single device. The device comprises a staff, a can holster, a grip, a trigger and a selector. The selector comprises a selector rod moveable in or alongside the staff. At one end of the selector rod is a selector knob and at the other is an engagement mechanism that engages the spray valve of each can, one can at a time. The engagement mechanism comprises a cam and a rocker arm with two opposing fingers, one to engage each spray can when selected. Optionally one or more flag holders may be attached to the staff for holding marker flags.

A tool for marking the location of a bonding plate concealed beneath a roof membrane. The tool has a magnetic attraction to the bonding plate and causes a marking assembly to vertically lower toward the roof membrane and rotate on an axle. Rotation of the marking assembly and vertical lowering causes the marking implement to come into contact with the roof membrane at a location corresponding to the location of the bonding plate beneath the roof membrane. A brake restricts the rotation of the marking assembly on the axle by coming into contact with an inner edge of a chassis. Contact between the marking implement and the roof membrane and the restriction of rotation of the marking assembly by the brake cause the marking implement to create a visible mark at a position corresponding to the location of the bonding plate beneath the roof membrane.

Location systems and methods for locating paint and other markings on a surface are described. More specifically, but not exclusively, the disclosure relates to smart paint stick devices and methods of use in locating and marking buried utility lines or other buried objects. One system for locating a buried object may include a buried object locator and a paint stick. The locator may include a tracking component configured to detect a location of a buried object. The paint stick may be configured to cause a paint container to dispense paint at a first position associated with the location of the buried object. The paint stick may include a position determination component configured to transmit one or more range vector signals that are detected by the tracking component. Sensors may be used to determine when paint is dispensed from a paint container, and to determine a color of the paint or a type of a marking.

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.

A paint container for use with a reusable dispensing apparatus, and the reusable dispensing apparatus are provided to dispense paint under pressure. The paint container includes a housing defining an interior space that is devoid of an internal valve, and a combination comprising a propellant combined with paint within the interior space. A container cap is installed on the housing to enclose the propellant combined with the paint within the interior space at an elevated pressure, and defines a channel that cooperates with a portion of the housing. A compressible gasket is disposed within the channel and compressed between the container cap and the portion of the housing to form a seal that interferes with an escape of the propellant combined with the paint between the container cap and the housing. A releasable fastener engages releasably couples the reusable dispensing apparatus to the container cap.
