发明名称 Jacket having an access section for insertion and removal of an inflatable bladder
摘要 A jacket for an inflatable bladder such as an exercise ball. The jacket has a durable cover with an access section having an inner panel defining an access opening. Outer panels overlie the inner panel and have edges which extend across the opening and are provided with closures. In use, the outer panels may be separated at fasteners so a bladder may be removed or inserted through the access opening. The inner panel and the outer panels may be a woven material with their weave oriented to resist distortion when the bladder is inflated and to assist in securing the closure. The cover may be any suitable material such as a coated nylon providing durability.
