Claims11
An inflatable play ball comprising:
- an outer casing formed of a flexible material that is substantially non-porous which assumes a desired play ball configuration when expanded, the outer casing having a first closeable opening and a second closeable opening;
- and
- a removable balloon formed of an elastomeric material, the balloon having a closeable opening and being inside the outer casing;
- wherein the second closeable opening includes a check-valve that permits evacuation of air from the outer casing when the balloon is inflated through the closeable opening in the balloon and through the first closeable opening in the outer casing and prevents inflow of air into the outer casing during use of the ball.

A method of inflating a play ball comprising:
- supplying an outer casing formed of a flexible material that is substantially non-porous, the outer casing comprising an opening with a check-valve therein;
- supplying a balloon formed of an elastomeric material and comprising a closeable opening;
- inserting the balloon in an uninflated state through the opening and into the outer casing while leaving the closeable opening outside of the outer casing;
- inflating the balloon by supplying air or a gas through the closeable opening;
- evacuating air from the outer casing through the check-valve as the balloon inflates;
- closing the closeable opening upon inflation of the balloon;

A kit comprising:
- an outer casing formed of a flexible material that is substantially non-porous which assumes a desired play ball configuration when expanded, the outer casing having a first closeable opening and a second closeable opening;
- and
- a balloon in its uninflated state formed of an elastomeric material adapted to be placed inside the outer casing through the first opening, wherein the second closeable opening of the outer casing includes a check-valve that permits evacuation of air from the outer casing as the balloon becomes inflated and prevents inflow of air into the outer casing during use of the ball.
