Benefits of technology

[0025] The metered dose apparatus provides an integrated metering chamber and dipstick that can be readily adapted to pre-existing containers. The apparatus does not require special valves and can be used with most conventional canisters. Thus, it is versatile and can be used with a wide variety of foamable compositions and containers without the need to redesign the dosage delivery system.

Problems solved by technology

Prior art foam metering devices have been described as inaccurate and imprecise.

Embodiment Construction

[0037] Turning now to the drawings, FIG. 1 shows a container 10 including a content 14 under pressure created by gas 12. The container 10 is hollow body which may be made from any material, for example, aluminum, tin-plate, plastics including polyethylene terephthalate (PET), oriented polypropylene (OPP), polyethylene (PE) or polyamide and including mixtures, laminates and the like. When the container is metal, the interior surface of the metal container preferably is laminated with a plastic material or coated with a lacquer or with a varnish to protect the interior surface of the container from corrosion. Corrosion may weaken the container and may also lead to a discoloration of the container's content. Preferred plastic materials for lamination and lacquers or varnishes for coating are epoxy phenolic, polyamide imide, organosol, PET, PP, PE or a combination thereof.

[0038] Content 14 is flowable and can be a liquid or a semi-liquid. Content 14 includes components to provide the d...

Abstract

Apparatus and method for delivering a predetermined quantity of content from a pressurized container include a container for housing a pressurized gas and a content; a valve for releasing content from the container; a metering chamber in fluid communication with the container and the valve and having an upper wall and a lower wall, the metering chamber defining a volume proportionate to a predetermined quantity of content to be delivered; and a movable partition comprising a seal positioned in the chamber and capable of moving from a first resting position to a second sealing position, the sealing position sealing fluid communication of the chamber with the valve. When the valve is opened to deliver content from the container, the movable partition moves from a first resting position to a second sealing position.
