Abstract

A carton for a portable two-component polyurethane foam spray kit has front and rear panels interconnected at their vertically extending ends with carton sides to form a rectangular opening closed at its bottom by bottom flaps. A top cover flap has valve openings allowing the kit user to open and close pressurized “A” and “B” polyurethane cylinders carried in the carton without opening the carton. The carton is carried by a strap secured to the cylinders extending through the top of the carton. A closeable, punch-out front flap formed as part of the front panel allows the kit hoses to be attached to the cylinders and the dispensing gun and stored for shipment and use within the carton between the cylinders and the front panel.

Claims

1. A portable two-component polyurethane foam spray kit suitable for shipping and in situ spraying of polyurethane foam comprising:

a) a cardboard container having front and rear confronting panels inter-connected at their vertically extending edges with side panels to form a generally rectangular chamber within said forward, rearward and side panels, and a top panel for closing the top of said chamber and a bottom panel for closing the bottom of said chamber whereby said container completely encases the contents therein;

b) a first pressurized resin containing cylinder and a second pressurized isocyanate containing cylinder, each cylinder having a dip tube extending from a manually actuated valve outside of and at the top of each cylinder to a position within and adjacent the bottom of each cylinder and each cylinder situated within said chamber with its bottom in contact with said bottom panel and its top adjacent said top panel;

c) a dispensing gun and a hose for each cylinder connected at one end to said cylinder valve and at its opposite end to said dispensing gun, said hoses with said gun at one end thereof coiled and positioned between said cylinders and one of said front and rear panels for storage and shipping of said kit, and

d) one of said panels having a fold out flap for removal of said hoses and said dispensing gun from said container when applying said polyurethane foam.

2. The portable spray kit of claim 1 wherein said top panel further includes knock-out openings adjacent said valves whereby said valves can be actuated to pressurize said hoses with said cylinders in an upright position.

3. The portable spray kit of claim 2 wherein said panel having a fold out flap is said front panel.

4. The portable spray kit of claim 3 further including means associated with said container and said cylinders for carrying said kit.
