Abstract: A membrane pouch, for rehydrating sterile intravenous and other solutions for non-sterilized fresh water, has a double bag construction. An inner bag made of semipermeable membrane material holds the sterile solutes to be rehydrated. The membrane material is permeable by water but impermeable to contaminants and a large molecular weight solute contained in the bag. An outer waterproof bag encloses the membrane bag and serves as a container for fresh water. Each bag has a sealable valve for providing access to the interior thereof. A high molecular weight dye located in the outer bag provides a visible indication of the existence of any discontinuity in the membrane bag. A low molecular weight, water soluble, non-toxic substance having a high osmotic pressure can be placed inside the membrane bag to accelerate the osmotic transfer of sterile water from the outer bag into the inner membrane bag.

Abstract: A self-inflating toy that provides amusement before and during inflation as well as after. The toy is formed from relatively flexible materials that define a sealed inner chamber which contains mixable chemicals that are separated by a membrane which is ruptured when the deflated toy is struck a firm blow. Upon rupture of the membrane, the chemicals mix and react to produce a gas that causes the toy to inflate as the sealed chamber becomes pressurized by the gas. In its deflated form, the toy is collapsed to assume a relatively flat, essentially two-dimensional state, thereby enabling it to fit inside an envelope or other essentially flat paper container in much the same manner as a greeting card. In one preferred form, the toy has three-dimensional outer surface portions that are printed and/or textured to provide features that attract attention such as a grimacing face that has expressions which change and are enhanced as the toy expands from a deflated state to its fully inflated state.

Abstract: An inflatable three dimensional figure that simulates an animal or a human personage, e.g. a panda or a policeman. The limb sections (arms and legs) extend angularly from opposite ends of a flexible pipe (tube) that extends through a hollow sleeve formed on the torso section of the figure. The limbs can be angularly adjusted to different positions (raised, lowered, etc.). Angularl adjustment of the limbs causes the flexible pipe to twist within the hollow sleeve; frictional forces between the pipe and sleeve hold the limbs in adjusted positions.

Abstract: A versatile multiple spout balloon network is provided with thin walled resilient, single or multiple spout balloons which may be interconnected to other balloons or a pole using plugs. Plugs provide for resilient and airtight engagement of balloons at their spouts. Plugs may include an air channel for passage of air between balloons and the network. The network may include one or more poles, each pole having several branches. Balloons may make an airtight and resilient engagement with the poles at branches using a plug. A stand may be used to erect the plug pole by inserting the pole into a fitting hole in the middle of the stand. A plug unit may comprise multiple surfaces attached to, or integrated at, a central point in different patterns.

Abstract: An inflatable toy simulating the mouth of an insect which includes a tubular mouthpiece, a sound-generating mechanism, a juncture between the mouthpiece and a pair of hollow arms, the arms being defined by first, medical and second terminal ends, the arms normally being folded with the second ends in end-to-end opposing relationship, and the material of the toy being so constructed as to maintain the arms in the latter position, and return the same from an inflated position at which the second ends of the arms project generally in opposite directions to each other with the overall effect thereof being that of the mouth of an insect.

Abstract: Three-dimensional balloon sculptures (50, 56, 66, 86, 88, 89, 90, 99, 125, 136, 137, 159, 160, 169, 178, 186) and methods of forming same from one or more basic balloon building blocks (106, 106', 106", 126, 159) each including at least one rigid lineal rod-like balloon former (100, 100', 138a, 138b, 149, 162, 174, 181, 182, 184) defining one or more lineal barrier(s) precluding distension of a portion of the sidewall of a conventional balloon of the type having a constricted neck portion (111) terminating at one end in an inflation aperture (112) and at the other end in an imperforate inflatable sidewall (108).

Abstract: An inflated toy is in a general form which is suggestive of a football player with his arm and hand in a passing position. A hook and loop fastener is on the hand of the player and on the football so that the hand may hold the ball. If the toy is tackled properly, the player may fumble the ball.

Abstract: An ambulatory animal toy includes a skeleton having a substantially horizontal spine with forward and rear ends defining forward and rear directions. Mutually spaced apart legs are attached to the spine and feet are attached to the legs. The feet are in frictional engagement with a walking surface and the spine can twist and bend substantially horizontally but is prevented from bending substantially vertically when the skeleton is pulled substantially in the forward direction.

Abstract: A water spouting bop bag includes an inflatable housing having ballast in a lower portion thereof. A spray head is connected at the top of the housing and water is delivered thereto from a garden hose via a tube in the housing. With water spouting from its top, a child punches the bop bag from an initial upright position, so as to tilt the water spout onto another player. The weight of the ballast restores the bop bag (and the water spout) to the initial upright position.

Abstract: An inflatable bag comprises a small sack which is charged with sodium bicarbonate and accommodating a small externally breakable container filled with an acidic solution. The small sack is enveloped in an inflatable bag member which is made of a synthetic resin having no permeability to the gas which is generated as a reaction between the sodium bicarbonate and the acidic solution. As the small container is collapsed by external pressure, the acidic solution flows out of the container into reaction with the sodium bicarbonate, thereby generating carbon dioxide gas. The small sack is punctured by the gas pressure with a sound of a bang or a whistle and, thereafter, the inflatable gas member is gradually inflated. It is possible to use a plurality of small sacks made of a material which exhibits small extension, such that one small sack is contained in another sack.

Abstract: A free-standing, self-righting punching bag having utility as a toy. The punching bag is sculptured and three dimensional; it is provided with a water-filled flexible enclosure at its lowermost end which serves as a counterweight to right the bag when it has been toppled by a punch or kick. In a first embodiment, a hollow tube member that also serves as a fill spout maintains the enclosure in its original shape at all times. In a second embodiment, a pair of strap members maintain the enclosure in its original shape and the fill spout is provided as a separate member which is positioned on the bottom of the toy.

Abstract: An inflatable toy construction that allows an inflated yet flat or non-bulbous center section of a toy to be flanked by inflated, bulbous parts. The center section is formed by an I-beam construction that is modified to allow free flow of air between the flat center section and the bulbous parts of the toy which flank the center section. The modification includes baffle walls that do not extend across the entire center section so that air can move from a center section compartment defined by a pair of baffle walls to other compartments defined by other baffle walls that also do not extend completely across the center section. The modification further includes a substantially imperforate wall that surrounds and defines the center section, which wall is provided with a pair of apertures to provide fluid communication between the interior space of the center section and the spaces defined by the bulbous portions of the toy.

Abstract: A gas-inflatable bladder toy is disclosed, in which a plurality of films are stacked with their peripheral edges being sealed for forming a bladder to be inflated by filling a required pressure gas therein, said bladder being adapted to be fed with an external gas and provided with an air valve in a flat double cylindrical form for checking an internal gas, or alternatively in which the same construction of the bladder contains a plurality of receiving bags separately receiving certain foaming agents which are chemically reacted upon mixing to produce a gas, these filling bags being broken by an external force. In accordance with the gas-inflatable bladder toy of the invention, the shape of the receiving body containing the preexpanded bladder 1 may be quite different from the shape of the expanded bladder 1 after opening the receiving body 7 and expanding to the given shape, thereby to provide an exciting bladder toy with a surprising effect.

Abstract: A toy in the shape of an animal has an opening to a cavity that contains an inflatable air cell, and a blanket that is adapted to be rolled and out of the cavity. The blanket is releasably connected to the toy.

Abstract: A water toy includes an inflatable housing having ballast in the lower portion thereof. A spray head is connected to the top of the housing and water is conveyed to the spray head from a garden hose through a tube in the housing. With water spraying from the top of the housing, the toy can be hit from an initial upright position so as to tilt to various angles but will resume its initial upright position.

Abstract: An airborne, free floating, lift-weight, balanced balloon having a closed envelope encompassing a fixed volume of lighter-than-air gas has ballast means fixed on the bottom of the envelope to tend to balance the weight of the balloon to equal the lifting effect of the gas, and to tend to cause the balloon to float in a desired horizontal attitude. At least one ballast member or a pair of ballast members form part of the ballast means and are fixed to the bottom of the balloon in symmetrical relationship to a vertical plane passing through the central horizontal axis of the balloon, ballast member(s) being constituted as a plurality of pressure sensitive removable weight control modules also arranged symmetrically with respect to a vertical plane passing through the central horizontal axis of the balloon when the balloon is in its desired attitude. These weight control modules are removed one or two at a time in order to balance the weight of the balloon so that it will float at a desired altitude.
