Balloon retaining and inflating structures, assemblies, and methods which provide arrays of multiple balloons in any desired configuration, and wherein the balloons are simultaneously inflated and the array can be repeatedly inflated and deflated for re-use.

A randomly deflatable balloon having a nozzle, and an insertable lightweight ball that can become lodged in the nozzle, thereby forming a ball check valve. The lightweight ball is preferably made from expanded polystyrene foam. The balloon is inflated after the ball is inserted into the balloon. When the nozzle is released to allow air to escape from the balloon, the ball eventually gets trapped in the nozzle of the balloon, thereby blocking the outflow of air. The ball can be dislodged from the nozzle by tapping the balloon, which causes the balloon to rocket through the air until the ball gets trapped again in the nozzle, whereupon the balloon stops moving due to escaping air, and then drops to the ground, partially deflated. This can be repeated until the balloon is completely deflated. The random partial deflation can be the basis of both solitary and multiplayer games.

An example embodiment of an apparatus includes a housing with an opening at a first end and a plurality of holes at a second end, a plurality of hollow tubes attached to the plurality of holes, a plurality of containers removably attached to the hollow tubes, and a plurality of elastic fasteners, each elastic fastener clamping each container to a corresponding hollow tube, such that when the containers are filled with fluid and detached from the corresponding hollow tubes, each elastic fastener seals each container with the fluid inside.

An inflatable toy includes a pump bladder having two one-way valves. One is used for inflation, and the other is used for deflation. A deformable bladder is connected to the pump bladder and located at a position close to the one-way valve used for deflation. The deformable bladder has another one-way valve used for deflation. The deformable bladder can be inflated by pressing the pump bladder repeatedly. The inflatable toy is a novel toy, allowing children to change the size of the inflatable toy as desired.

A balloon bursting frame apparatus is provided so as to have a plurality of outlet nozzles, each outlet nozzle operatively associates with an inlet of a balloon by way of a preloaded adaptor. The preloaded adaptor provides a barbed conduit with raised flanges that define a lock groove to which a retainer ring of connection mechanism can snap-connect to. The connection mechanism also provides a cable tie for cinching the inlet of the balloon securely in place.

A modular inflatable structure facilitates versatile three-dimensional configurations through a frame supporting multiple inflatable components. The structure comprises a frame constructed from malleable plastic members that provides structural integrity while maintaining flexibility. The frame incorporates a plurality of multi-way-valves affixed at junction points, which receive and secure inflatable attachments while regulating airflow. Attached to these valves are numerous inflatable balls creating visual interest and dimensional variation. An inflation valve assembly receives at least one longitudinal member and regulates airflow into and out of the inflatable attachments. Internal hollow channels within the longitudinal members provide continuous airflow pathways throughout the structure. The modular inflatable structure may include detachable accessories with pre-inflated balls connected via stems that couple to the frame using clips. This design facilitates rapid assembly and reconfiguration for temporary installations across various applications, with the frame forming a backbone to support modular arch structures while maintaining pressure stability through one-way valve mechanisms.

An automatic self-sealing balloon, includes a balloon body, a sealing member and a water injection port arranged on the balloon body. A cavity is formed inside the balloon body, and the water injection port communicates the cavity with external environment. The sealing member is provided in the cavity, and the sealing member is made from materials of less dense than water. The sealing member's peripheral contour is greater than the water injection port's inner contour. When the cavity of the balloon body is filled with water or inflated with gas to a full extent state, the sealing member blocks the water injection port to realize automatic self-sealing function.

The invention provides a water polo water injection assembly and a water polo water injection device. The water polo water injection assembly omits disassembly with an external water pipe or a water injection cylinder, is convenient to use, and is uniformly filled with water polo. The injection tube bundle is short in length, low in processing cost, wide in application range and low in water pressure requirement The water polo water injection device realizes continuous water extraction and pressure injection, thus realizing water polo water injection without the aid of water pipes, convenient use, uniform water polo water filling and simple replacement.
