Abstract

An inflatable nursery toy typically consisting of a large generally barrel-shaped inflatable outer bag composed of soft, limp, flexible and non-resilient sheet material such as plastic, with donut-shaped cuffs at either end thereof. A smaller, separately inflatable cylindrical tube, usually composed of the same plastic material as the outer tube, is located within the barrel and is inclined lengthwise of the barrel relative to the axis of symmetry thereof. A plurality of balls are located within the cylindrical tube, and these balls travel lengthwise due to gravity, as a child rolls the barrel along the floor.
