A dispenser includes: a plunger; a dispensing portion configured to dispense and suction liquid in response to an advance and a retraction of a distal end surface of the plunger along an axial line. The dispensing portion includes: a surrounding portion surrounding the distal end surface of the plunger about the axial line to define an accommodation chamber for accommodate the liquid to be dispensed; and an end portion facing the distal end surface of the plunger. The surrounding portion includes an inlet opening into the accommodation chamber to receive the liquid into the accommodation chamber. A distance from the inlet to the end portion is less than or equal to half of a maximum stroke of the distal end surface of the plunger.

A fluid dispensing device includes a housing and a reciprocating piston fluid pump coupled to the housing. The reciprocating piston fluid pump includes a piston disposed within a cylinder. The piston is configured to pressurize at least one pumping chamber. A motor is coupled to the housing and connected to the reciprocating piston fluid pump to actuate the piston. A wobble assembly connects the motor to the piston of the reciprocating piston fluid pump. A spray tip connected to an outlet of the at least one pumping chamber.

A discharge apparatus for an aerial vehicle is provided which is capable of mounting an aerosol container by effectively utilizing a space outside an airframe.

The discharge apparatus for an aerial vehicle, in which a content is discharged through a nozzle from an aerosol container mounted on an airframe, is characterized in that the aerosol container is mounted outside the airframe, and is arranged so that a central axis of the aerosol container is along a pitch axis of the airframe, or arranged on an extension portion such as a small wing extending from a fuselage of the airframe, an arm portion provided with a rotor blade, a leg portion for taking off and landing, or the like, with the aerosol container and the nozzle being connected to each other through a tube.

A pumping assembly comprises: a motor (24) including a stator and a rotor, the rotor configured to rotate relative the stator on a pump axis (PA); a drive mechanism (24) connected to the rotor, the drive mechanism (24) configured to receive a rotational output from the rotor and convert the rotational output into a linear input along the pump axis to cause pumping of the fluid; and a piston (34) connected to the drive mechanism (26) to receive the linear input and disposed coaxially with the drive mechanism (26) and the rotor, wherein the piston (34) is configured to reciprocate axially along the pump axis to pump fluid.

A play apparatus has a gas filled balloon and an opening through which fluid is squirted or otherwise released. Fluid is delivered to the opening from an adjacent or nearby reservoir which is connected to at least one hollow tube whereby liquid is transferred from the reservoir to the release point on or adjacent to the balloon, such that the buoyancy of the balloon is unimpeded, for the purposes of play and amusement.

A paint baking oven comprises an oven body and a hot air supplier that supplies hot air into the oven body. The paint baking oven bakes a wet coating applied to a vehicle body while conveying the vehicle body. The vehicle body includes a body exterior part and a narrow portion. The oven body is configured to include a spot baking region in which the hot air is blown primarily toward the narrow portion to locally bake a coating film applied to the narrow portion.

An electrically powered, compact, ready to use sprayer that includes a main housing. When the sprayer is used in conjunction with an electric motor, self-feeding undulating tentacles, a spinning element, a spherical boot, spherical boot outlet, feed hose, and an extended wand outlet it is able to pump low and high viscosity fluid, create a liquid spray, and dispense fluid in the forward direction with very few moving parts and minimum energy.

Provided is a discharge apparatus for an air vehicle, capable of reducing a loss of discharge pressure from an aerosol container. The discharge apparatus for an air vehicle discharges contents from an aerosol container 10 mounted on an airframe 101 through a nozzle 15. The aerosol container 10 is mounted on an exterior of the airframe 101, and one end of the nozzle 15 is supported by a discharge end part of the aerosol container 10 via a pipe joint 17 that allows the nozzle 15 to rotate so as to be rotatable around at least one rotation axis M.

The misting system has, in one embodiment, two seats with misting heads above each seat. A platform supports the seats, a tank, a pump and a power source. A supply line couples the tank-supplied pump and the misters. Removable canopy is mounted above seats by vertical and curvaceous struts and the misters are mounted on the struts. A user actuated UA control on the seat(s) activates pump ON to release mist. Wheels make the module mobile. Battery, solar power, and chiller are options. A countdown timer turns OFF the pump or controllable, inline valves after initial activation of the UA control. A level sensor in the tank alerts the user via a user display. A pressurized system can be used. Multiple modules coupled together are controlled by a master module with master controls.

A toilet tissue mister includes a cabinet with an open lower front section for receiving a user's hand bearing toilet tissue. A liquid-containing bottle is maintained within the cabinet above the open lower section. A spray head is positioned at a top portion of said open lower front section and a pump is interconnected between the bottle and the spray head. A control circuit is interconnected with an optical transducer switch maintained within said open lower front section and, upon sensing the presence of a user's hand, actuates the pump for a duration of time sufficient to coat the toilet tissue in the user's hand with a spray mist from the spray head.
