Benefits of technology

The solution provides high-quality foam mixing with accurate chemical control, reduced waste, and lower replacement costs, ensuring efficient operation and ease of maintenance with a compact, lightweight design suitable for handheld or table-mounted use.

Problems solved by technology

The above hand-held apparatus are generally inaccurate in the proportions of chemicals they mix and provide a low quality foam mix.
As foam materials harden within a short time, remnants of the foam may harden within the dispensing apparatus and clog flow passageways.
In addition, a delivery conduit is required in medical applications but not in packaging applications.

Embodiment Construction

[0052]FIG. 1 is a schematic illustration of a foam generating and dispensing system 100, in accordance with an exemplary embodiment of the invention. System 100 comprises a base 110 which includes a recess 112 sized and shaped to receive a hand-held foam dispensing gun 120. Optionally, a battery (not shown) of gun 120 is charged when the gun is properly placed in recess 112. Base 110 optionally further includes a plurality of recesses 130 adapted to receive chemical containers, and heat the containers while they are in the recesses. In an exemplary embodiment of the invention, recesses 130 host containers 132 of a chemical A, e.g., and containers 134 of a chemical B. In an exemplary embodiment of the invention, chemical A comprises a polymeric isocyanate or a fluorocarbon, while chemical B comprises polyols, catalysts or flame retardants. It is noted, however, that system 100 is not limited to use with any specific chemicals and has advantages which are useful for mixing many chemic...

Abstract

A self-contained foam dispensing device includes a casing, a mixing chamber, a port adapted to receive one or more containers including a plurality of chemicals in a plurality of compartments and a flow generator adapted to induce flow of chemicals from the compartments toward a mixing chamber, the flow generator being located between the mixing chamber and the port. When the one or more containers are in the port the one or more containers move with movement of the casing.

Description

RELATED APPLICATIONS[0001]The present application claims the benefit under 35 U.S.C. 119(e) of U.S. provisional application 60 / 556,883, titled “Hand-Held Dispenser”, filed Mar. 29, 2004, the disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to foam dispensers and particularly to hand held foam dispensers.BACKGROUND OF THE INVENTION[0003]Foam materials are commonly used for packaging. The foam is generally generated by mixing two chemical components, which harden within about 10-30 seconds. In many cases, a foam dispensing gun is used to generate the foam at the packaging site. U.S. Pat. No. 4,262,848 to Chabria and U.S. Pat. No. 5,462,204 to Fiin, the disclosures of which are incorporated herein by reference, describe such guns which are connected through tubes to large containers including the chemicals used in forming the foam. The dispensing gun generally includes a pair of pumps which pump the chemicals out of the c...
