    Abstract: A kick-strengthening practice soccer ball is given a little extra weight but preferably softened also for enhance shock absorption when kicked. The practice ball has an inflatable bladder, a carcass of tough durable material, and an intermediary sheath of substantially non-stretchable, flexible material for restraining expansion of the bladder when inflated to pressure. Thus the sheath thereby reduces the outward pressure on the carcass while also increasing the dimensional stability of the ball. A shock-absorbing weighting material interposed between either the bladder and sheath or sheath and carcass. The weighting material accounts for between about 4% and 40% of the total weight of the practice ball when inflated to pressure. If a nominal average weight for a standard matchball is taken to be between 14 to 16 ounces, the weighting material adds an additional increment from anywhere between about 1 and 10 ounces.

    Abstract: A squeezable plaything which resembles an animal-like or humanoid figure having appendages projecting therefrom. The plaything includes a hollow core molded of resilient plastic material shaped to resemble the figure and provided with an orifice which renders the core collapsible. Enveloping the core and generally conforming to the figure and its appendages is an outer shell formed of flexible transparent plastic film material. Injected into the core through the orifice is a charge of oil which when the plaything is squeezed and deformed, oil and air are then discharged through the orifice into confined spaces between the shell and the core. And when the plaything is released to recover its shape, the oil and air are then sucked back through the orifice into the core. These actions generate squishing sounds, as if the figure were walking on soft mud.
