International ClassesA63B 041/00A63H 003/26 AbstractA squeezable toy ball which simulates a human organ such as the intestine, the ball when squeezed and released then generating a gurgling sound similar to that produced by a functioning intestine. The ball comprises a generally spherical outer shell formed of flexible plastic film encasing a hollow inner core. The core is molded of resilient plastic material to simulate the appearance of an intestine and is provided with an orifice which renders the hollow core collapsible. Injected into the core through the orifice is a charge of oil or other viscous liquid. When the ball is squeezed and deformed, oil and air are discharged from the orifice into the confined spaces between the core and shell, and when the ball is then released to recover its normal shape, oil and air are then sucked back into the shell, these actions producing a gurgling sound. | |
