Abstract
A foam generator includes a body and a removable insert positioned within the body. The insert is held to the body by a cap releasably engaging a mating surface of the body. The body includes a plurality of inlets for foam constituents adjacent the mating surfaces of the body and an outlet for the foam opposite end. To change the insert, the can is disengaged from the mating surface without the need for tools and without disturbing the inlets. A new insert can be placed within the body and a cap of the new insert engaged with the mating surface without the need for tools.
Claims8
A device for producing a foam composition from a fluid, containing chemicals, and compressed air, having
- A. A housing comprising a tubular member of a defined length and uniform cross-section, wherein said tubular member has an open top end and an open bottom end,
- a. said housing including at least one fitting on said housing for attachment of a feed line for a fluid containing chemicals, and at least one fitting on said housing for attachment of a feed line for compressed air;
- and
- b. means for sealing engagement of a cap on each open top and open bottom end of said housing;
- B. A foam generator insert adapted for insertion and removal through said open top end of said housing, wherein said insert comprises an elongated rigid support and a linear array of discrete elements of porous media arranged in fixed positions, and in spaced apart relation to each other, along said rigid support;
- C. A top cap adapted for sealing attachment to the open top end of the housing, so as to permit insertion and/or removal of the foam generator insert from within said housing upon removal of said cap from said housing;
- and
- D. A bottom cap adapted for sealing attachment to the open bottom end of the housing, wherein said bottom cap is further provided with a discharge port and engagement means for attachment to a fitting of an applicator for distribution/dispensing of foam formed within said foam generator.
