A reservoir-based storage and delivery system has a reservoir body equipped with a top assembly, a bottom assembly and a piston assembly. The contents of the reservoir are allowed to expand and contract during the thermal cycle due to the ability of the piston assembly to float within the reservoir, which eliminates the need for dead head space.

An adapter for a canister filling system includes a body having an opening that is shaped to enable insertion of a valve of a gas canister for holding a pressurized or liquefied gas, into an interior space of the body, leaving a sealed gap between at least a portion of a lateral aspect of the valve and an internal surface of the body facing the interior space; and at least one channel that is configured to conduct pressurized or liquified gas from a canister filling system into the sealed gap in the interior space, so as to reach one or more lateral exterior ports of the valve of the gas canister that open laterally to a longitudinal axis of a body of the gas canister, when the valve is inserted in the interior space, to facilitate filling of the gas canister with the pressurized or liquified gas through said one or more lateral exterior ports of the gas canister.

The invention comprises a method and apparatus for packaging a dispensable substance, including the steps of: placing a first product component into a container; adding a second product component into the container at an initial pressure of less than 1.31 atm, the container comprising a valve dispensing port; sealing the container; and increasing pressure in the container through a phase change of the second product component to a final pressure in the container, the final pressure at least 0.26 atm greater than the initial pressure. Optionally, the second product component warms in the container at least ten degrees Celsius and undergoes a phase change from a solid or liquid to a gas, which increases pressure in the container and functions as a propellant and/or as an expansion agent.

A spray system for dispensing a homogenous mixture of a liquid formulation and propellant as an atomized aerosol where a fill cup containing a liquid base is connected to a charge can to pressurize the inside of the fill cup and to act as a propellant. The charge can is attached to the fill cup through a fitting in fluid communication with the interior of the fill cup, where the fitting may be configured to allow the pressurized charge can to be detached after adding a propellant compatible with the liquid base to the fill cup. Preferably the liquid formulation is a paint base that can be tinted at the point of sale before charging with the charge can.

The present device dispenses product from a pressurized container. The device has a metered valve that dispenses a predetermined fixed quantity of product upon actuation. The metered valve can be configured by the customer with a spacer to affect the amount of product continually metered.

A device for dispensing a fluid substance includes a pressurised container associated with a dispensing valve featuring a supply conduit and a stem endowed with a cavity through which the fluid substance is dispensed, a chamber housed inside the container, and arranged so as to surround at least part of the body of the valve, the chamber delimited by a deformable wall and at least part of the body, the valve being of the three-way type, configured so that when the stem is in a first position, the cavity is isolated from the supply conduit and from the chamber, while the supply conduit is in communication with the chamber, wherein when the stem is in a second position, the cavity is in communication with the chamber, and wherein when the stem is in a third position, the cavity of the stem is in communication with at least the supply conduit.

A pouch reservoir for a pressurized dispenser casing, having a pouch and a dome provided, in its lower part, with a tubular base provided with an external profile for receiving and welding a neck of the pouch and, in its upper part, with a housing for receiving a valve for dispensing a product contained in the pouch. The tubular base and the neck of the pouch welded to the external profile are each provided with a degassing hole at the external profile.
