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.
