The apparatus and method can be used to inflate, seal and deflate an inflatable body when the neck or opening portion of the inflatable body is inaccessible or unexposed as well as when the neck or opening portion of the inflatable body is accessible and exposed.

Abstract: A balloon device includes a plurality of aesthetically discrete balloon members, wherein at least a first one of the aesthetically discrete inflatable members defines a first aesthetic moiety, at least a second balloon member defines a second aesthetic moiety; and a connecting member connecting member that connects the balloon members has an appearance that maintains an aesthetic separation between the first and second aesthetic moieties. The connecting member may be transparent, translucent, or have a color that matches the color of a background where the balloon device is intended to be displayed.

Abstract: A sound-producing device for producin a loud noise in support of one's team during sporting events.

Abstract: The present invention is a toy water gun with turreted multiple water bomb launchers. By the attachment of the turreted multiple water bomb launchers with water bomb devices to a toy gun the present invention provides new functionality of the toy gun by being able to simulate multiple water "explosions". A turret with a plurality of water bomb devices attached is incrementally rotated so as to align each one of the individual water bomb devices with the release trigger. The water bomb device has a main housing with a frontward and rearward portion rotatably connected to one another and a passageway through both portions for receiving a shut off valve. The shut off valve is located within the housing and connected to both portions.

Abstract: A water toy has the shape of an aerial bomb or rocket with generally bulbous, resiliently flexible body and a removable tail member with fins, The water toy includes a resilient shell having a mouth and an internal pointed member facing the mouth. A balloon has a mouth with a lip that fits around and engages the mouth of the shell with the balloon body in the shell. The two mouths are sufficiently large to receive ice cubes. A cover member is fitted over and releasably engages the mouth of the shell sufficiently snugly to seal the mouth of the balloon on the mouth of the shell. The cover member has a recess with a one-way check valve to permit the balloon, which is sealed between the cover member and shell, to be filled with water. The tail member is received in the recess and releasably engages the cover member. Dispersion passageways extend from the inner through the outer surfaces of the shell.

Abstract: The present invention is a toy water bomb device with a main housing which includes an upper portion and a lower portion rotatably connected to one another and a passageway through both the upper and lower portions for receiving a shut off valve. The shut off valve is located within the housing and connected to both the upper and the lower portions and adapted so that when the upper and lower portions are rotated relative to one another, the shut off valve is moved from an open position to a closed position. There is a locking mechanism connected to one of the upper and lower portions, and releasably connected to the other portion such that rotation of the upper portion relative to the lower portion will move the shut off valve to a closed position and the locking mechanism may then be used to hold the shut off valve in its closed position until subsequently released. There is also an expandable bladder which is filled with liquid and expends liquid when the device is activated and the valve is opened.

Abstract: The cartridge-type water bomb water gun conversion device utilizes a cartridge-type water bomb which can be used by itself to release a burst of water or be inserted into a water gun which can convert the cartridge-type water bomb into a reservoir of pressurized water for discharge through an orifice producing a "squirt" type release. The cartridge-type water bomb has an expandable bladder fixedly attached to frontward and rearward portions of a main housing which effect a shut off valve in a passageway when the frontward and rearward portions are rotated relative to one another. The water gun has a gun housing and a cocking and engaging lever which accepts the cartridge-type water bomb against a nesting section connected by way of an exit tube to a discharge orifice at a gun barrel end. The pressurized water in the expandable bladder may be released by pulling a pinch trigger.

Abstract: The present invention is a toy water bomb--mounted water gun. By the attachment of the water bomb device to a toy gun the present invention provides new functionality of the toy gun by being able to simulate a water "explosion".

Abstract: A composition, method and apparatus for preserving the glossy, smooth exterior finish of a latex balloon wherein the exterior surface of the balloon is coated with an anionic aliphatic dispersion of polyester urethane material and dried. Coating can be accomplished by several methods including dipping in a bath. The coating can be applied either when the balloon is not inflated or inflated. The coating significantly increases the lifetime of the balloon without significantly decreasing buoyancy.

Abstract: A steam locomotive-whistle model and toy providing realism in appearance in sound and operation of a real locomotive, by responding to blowing effort by the mouth or of a balloon which operates parts to run the locomotive and to emit sounds exactly simulating those of a real locomotive. It includes a smokestack and detachable cover, simulating smoke, to prevent air from escaping through its inlet hole. Also it includes a rear air intake pipe which is blown by the mouth to force air into an air chamber, thence into air ports and a cylinder to cause a piston to move away from the air inlet end of the cylinder.

Abstract: The present invention comprises a base coupled to a water source, the base outputting a stream of water for supporting a toy ball in mid air. The base includes filtering device for substantially eliminating turbulence from the water stream so that it is substantially laminar. The flowing stream contacts a toy ball and lifts it into a position of equilibrium where the upward force of the stream balances the downward force of gravity acting on the ball so that the ball is suspended in mid air. The flowing water clings to the surface of the ball and generates a force tending to center the ball in this supporting stream. If the ball becomes off center, an unequal force on the side of the ball furthest from the center of the stream will force the ball back to the stream center.

Abstract: A toy spa (10) is provided with water (56) and an aerating manifold (18) in the base (16) of the spa. Pressurized air is provided to the manifold via a bellows pump and passes through the water from openings (20) in the manifold. To reduce the surge effect of the bellows pump an expandable reservoir means (40) is provided between the bellows pump and the aerating manifold (18). Air is pumped from the bellows pump directly into the expandable reservoir through a one way valve (32) moved by the pressurized air. Air exits from the expanded reservoir via a restricted opening (44) which enables the pressurized air to be first stored within the expandable reservoir and to then be delivered to the manifold in a continuous, even manner.

Abstract: A noise making valve for a toy balloon includes a casing enclosing a moveable valve body and a resonant reed disposed upstream of the valve body. A perforated membrane substantially closing the end of the casing opposite the balloon is depressable to lift the valve body from its seat, causing emission of a tone. The valve body is positively enclosed in the casing, and the reed is protected by folded-over tabs, such that no part of the valve is removable by the user. Safety features also include an enlarged trumpet shape and a restriction preventing a complete sudden ejection of the valve from the balloon.
