The invention is in the field of three-dimensional hollow novelty items and their manufacture, particularly items such as artificial pumpkins that the consumer desires to carve or alter after purchase. Disclosed is a carvable novelty article, such as an artificial Halloween pumpkin, comprising a polyurethane shell substantially surrounding an interior volume and having a thin, elastomeric coating, such as an acrylic, on the exterior surface of the shell. The carvable article can be formed by an inventive process in which polyurethane foam material, such ...


A process of applying polyurethane foam material comprising: (a) placing a generally spherical, hollow mold and a spray nozzle so as to position the nozzle along a central axis of the mold; (b) spraying polyurethane composites through the nozzle and directing said composites radially at the inside surface of the mold, causing the composites to form a foam material against portions of the inside surface at which the composites are sprayed; (c) moving the mold and the nozzle relative to each other so as to cause the mold to revolve axially with respect to ...
