发明名称 Pump ball
摘要 An inflatable throw toy having a flexible wall defining an enclosure adapted to be thrown when inflated. A manually operated pump is fixed to the flexible wall. The pump includes a flexible resilient pump wall defining a closed pump chamber. The pump wall includes an actuator surface having an inlet hole therethrough, the inlet hole communicating with the closed pump chamber. The actuator surface is exposed to an exterior of the flexible wall and is surrounded by the flexible wall. The pump includes a one-way outlet valve in the pump wall at a location spaced from the inlet hole and communicating with an interior of the enclosure whereby pressing the actuator surface while covering the inlet hole causes the pumping chamber to contract, discharging air from the pumping chamber through the one way valve into the flexible wall for inflating the toy.
