A method and apparatus of making an aerosol container. A polymeric container may be provided. The container may have a closed end bottom and a neck longitudinally opposed to the closed end bottom. The container has an internal container volume. A valve and a bag may be provided and a portion of the valve and the bag may be disposed within the container. The bag has a first bag volume. A portion of the at least one of the neck and the bag may contact a portion of the valve to form a temporary seal. Propellant may be introduced into the container. The bag may be collapsed from the first bag volume to a second bag volume. The pressure of the propellant and the pressure within the bag equilibrate. The valve may be joined to the container and the propellant may be sealed within the container.

A method for manufacturing a discharge product includes the steps of: preparing the double pressurized container including an outer container; an inner container stored inside the outer container and having flexibility; and a plug for sealing both of the outer container and the inner container; charging a concentrate inside the inner container; contracting the inner container before or after charging the concentrate; tightly mounting the plug to a mouth of the inner container; charging the pressurizing agent between the outer container and the inner container through a space between a mouth of the outer container and the mouth of the inner container; and tightly closing the space between the mouth of the outer container and the mouth of the inner container by the plug.

A spray delivery system with minimal pressure loss can is used with an aerosol container having a valve. The system includes a vertically extending conduit having an opening at a lowermost end conduit and two openings through a surface at an opposite end. The surface is disposed at an angle relative to a vertical. The system also has a first horizontally extending conduit communicating with the vertically extending conduit though one of the two openings and a second horizontally extending conduit fluidly communicating with the vertically extending conduit though the other one of the two openings. A manifold defines an inner annular volume and fluidly communicates with the first and second horizontally extending conduits. A spray nozzle insert is in fluid communication with the manifold. The spray nozzle insert has a plurality of blades that radiate inward and connect with a center round well having a sharp end.

An aerosol device having a bowl with a bottom defining a drain, and a side wall extending from the bottom to a rim. A nozzle is disposed within the bowl. The nozzle defines a chamber and an outlet orifice directed toward the side wall of the bowl. The aerosol device includes a liquid container fluidly coupled to the nozzle via a first conduit having an outlet tip disposed within the chamber of the nozzle and a second conduit connecting a source of pressurized gas to the chamber of the nozzle. The outlet tip is in the form of a tube defining elongated slots communicating from inside the tube to outside the tube, the slots each having a width defined between two parallel tube surfaces. The aerosol device generates submicron liquid droplets, and is suitable for disinfecting porous articles in an enclosed volume.
