A self-inflating toy that provides amusement before and during inflation as well as after. The toy is formed from relatively flexible materials that define a sealed inner chamber which contains mixable chemicals that are separated by a membrane which is ruptured when the deflated toy is struck a firm blow. Upon rupture of the membrane, the chemicals mix and react to produce a gas that causes the toy to inflate as the sealed chamber becomes pressurized by the gas. In its deflated form, the toy is collapsed to assume a relatively flat, essentially two-dimensional state, thereby enabling it to fit inside an envelope or other essentially flat paper container in much the same manner as a greeting card. In one preferred form, the toy has three-dimensional outer surface portions that are printed and/or textured to provide features that attract attention such as a grimacing face that has expressions which change and are enhanced as the toy expands from a deflated state to its fully inflated state. The inflation of the toy may be rendered even more entertaining by incorporating within its structure components that have surface portions that engage and move relative to each other during inflation of the toy to generate various types of entertaining noises. Once inflated, the toy retains its inflated form to provide lasting amusement.

A hollow self-inflatable amusement device comprising, a sealed hollow structure for flexible material which when inflated defines a substantially ball-like configuration, said structure being formed from a pair of superposed sheets of said flexible material, said sheets being free of apertures or access openings over the surfaces thereof, said sheets having a peripheral bonded seam joining the sheets together, with each sheet having excess material lying in non-planar relation within the seam periphery when said structure is in a non-inflated and generally collapsed state, said excess material of said superposed bonded sheets in said non-inflates state including opposed outwardly convex generally part-spherical surfaces within the perimeter of said peripheral seam, thereby together with said peripheral seam defining a configuration which is substantially self-sustaining for ready handling and manipulation prior to impact and inflation, normally inactive gas-generating means including a rupturable container containing a gas-generating chemical received within said hollow structure between said sheets, said gas-generating means being responsive to impact pressure forces against the surfaces of said sheets to rupture said container and cause generation of a gas by said gas-generating means within said hollow structure to inflate the same, said sheets and said gas-generating means cooperating to preclude rupture of said sheets under said impact forces thereby to maintain the integrity of said sealed hollow structure, said gas-generating means controllably generating said gas following impact over a period from about 15 seconds to 2 minutes, thereby slowly inflating said hollow structure from the initial configuration thereof including said excess material inwardly of the sheet periphery to a final inflated form of generally ball-like appearance with a taut, generally smooth and unfolded surface, thereby permitting protracted observation thereof during inflation for amusement and interest, and, said flexible material being substantially impervious to rapid leakage transmission of said gas therethrough, thereby to maintain the inflated configuration for a substantial period of time for observation, handling and enjoyment.
