A paint cartridge includes a housing and a piston slidably disposed within a cavity in the housing to divide the cavity into a paint chamber and a solvent chamber. A valve assembly extends through an aperture in the piston to selectively put the paint chamber in fluid communication with the solvent chamber. A solvent inlet provides solvent to the solvent chamber to move the piston. Movement of the piston discharges paint from the paint chamber through the paint outlet.

A novel canister storage system, mixing system, canister assembly, dispensing system, and tracking system. In one or more embodiments, the systems are used for storing, mixing and dispensing fluids.

An apparatus for conveying viscous material out of a barrel-like container having a container bottom and a container wall that extends upward from the container bottom has a follower plate for closing off the container, which plate is movable in the direction toward the container bottom, lying against the inner surface of the container wall, which surface faces the container interior, and which plate has a dome that extends upward from an underside intended to lie on the viscous material, which dome opens, in the center, into a material exit opening. The apparatus has a pump for conveying the viscous material through the material exit opening. At least one displacement body projects into the dome through the material exit opening and is connected with the pump for displacement of the material situated in the dome and/or air situated in the dome, and at least one closeable venting opening vents the dome.

Exemplary foam pumps, refill units and foam dispenser systems are disclosed herein. One exemplary refill unit includes a container and a foam pump secured to the container. The foam pump includes an outer housing, an inner housing and a cap. An air pump chamber is formed at least in part by the inner housing. In addition, a liquid pump chamber is formed at least in part by the inner housing. At least a portion of the liquid pump chamber is also formed by the outer housing. An air outlet is located at the bottom of the air pump chamber, which connects to an air outlet passage formed at least in part by the outer housing and the inner housing. Air and liquid dispense tubes are included as well as a mixing chamber located remotely from the foam pump.

A water amusement and hydration bicycle can include a bicycle frame and a container to contain water carried by the bicycle frame, the container having an outlet port and a multipurpose port. The bicycle can also include an amusement nozzle removably coupled to the outlet port. The bicycle can further include a drinking nozzle removably coupleable to the multipurpose port. The bicycle can still further include a water pump carried by the bicycle frame and operable to pump the water from the container through the outlet port for delivery to the amusement nozzle. In addition, the bicycle can include a gas pump operable to pressurize gas in the container to move the water from the container through the multipurpose port for delivery to the drinking nozzle when the drinking nozzle is coupled to the multipurpose port. The multipurpose port can be coupleable to a water source to provide water to the container.

A sample dispenser includes a dosing unit, a cradle assembly, and tubing connecting the dosing unit and the cradle assembly. The dosing unit is configured to dispense sampling amounts of a flowable substance and includes a nozzle and a mechanical pump communicating with the nozzle. The cradle assembly includes a priming cradle configured to hold a compressible container of the flowable substance and to force the flowable substance out of the compressible container by applying a compressive force to the compressible container. The tubing allows communication of the flowable substance between the compressible container and the pump.
