In order to accomplish the objects of the present invention, there is provided a method for filling containers with fluids. A method provides a container made of an elastic material, the container having an internal chamber and a neck with an opening. A plug is provided inside the chamber, the plug having a buoyancy that allows it to float when fluid is introduced into the chamber. A fluid is introduced into the chamber, causing the plug to float until the plug enters the neck and seals the neck.

A vent balloon for use over an air vent including an inflatable body operatively attached to a base on a proximal side, and a removable adhesive attached to a distal side of the base for attaching to an air vent. A method of using a vent balloon by removably adhering an inflatable body of the vent balloon through a base to an air vent, flowing air through the inflatable body, and inflating the inflatable body. A vent balloon for dispersing scent in a room, including an inflatable body operatively attached to a base on a proximal side, a removable adhesive attached to a distal side of the base for attaching to an air vent, and at least one scent mechanism operatively attached to the vent balloon for dispersing scent in the room. A method of dispersing scent in a room using the vent balloon.

A tethered balloon assembly the balloon, to be inflated via the tether which is to be subsequently closed by a one way valve to keep the balloon inflated and allow additional inflation as desired, controllable by its tether.

A balloon apparatus utilizing a lighter-than-air portion and an appurtenance attached to the lighter-than-air portion. A connector is selectively linked to the appurtenance and the lighter-than-air portion and manipulates the rotational position of the appurtenance relative to the lighter-than-air portion.

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

A gift box with a self-inflating balloon is designed to be shipped to a recipient through the mail. A lid of the box is configured to be opened and may display a personalized message relating to a special occasion of the recipient. The box includes the balloon, which may be hidden from view in a compartment of the box. The box includes a switch that is configured to be actuated by the recipient. Upon actuating the switch, an inflation device is activated and begins to inflate the balloon, which emerges from the compartment of the box. A vibrating motor inside the box may synchronously cause the box to vibrate. After a pre-determined amount of time, the inflation device and motor deactivate, and a valve seals the air inside the balloon. Once the balloon is inflated, the gift box and balloon may be displayed for the recipient.

A balloon includes two joined plastic films. The balloon includes: a gas supply valve sandwiched between and joined to the first film and the second film; a first chamber receiving air supplied from the gas supply valve for expansion; and a second chamber communicating to the first chamber. The gas supply valve includes a gas passage that extends from a gas inlet positioned on an outer side of the second chamber to an inside of the first chamber through the second chamber. Part of the first film and the second film between the first chamber and the second chamber and between the gas passage and a peripheral edge of the balloon are joined together to form a first weld portion and a second weld portion. The first weld portion is formed on an opposite side of the second weld portion with the gas passage sandwiched therebetween.

A balloon including an inflatable body operatively attached to a base on a proximal side, the base including a cavity for filling with items, wherein the inflatable body is inflated by an air vent or a fan operatively attached to the base. A method of using the balloon, by placing the balloon at a display location, flowing air through the inflatable body, inflating the inflatable body, and providing access to items within the cavity. Reversible packaging including a packaging body having a first design on a first side and a second design on a second side. A method of using reversible packaging, by a user purchasing a product contained within reversible packaging showing a first design, the user removing the reversible packaging and reversing the reversible packaging to show a second design, and the user securing the reversible packaging around the product showing the second design.

An inflatable display assembly includes a base member to which the inflatable body is permanently attached. The base member has a channel therethrough, one end of the channel being affixed to an opening in the fabric of inflatable body. An external air blower unit may be removably attached to base member at one end of said channel to provide a flow of air through the base member and then into the inflatable body.

A tethered balloon assembly the balloon, to be inflated via the tether which is to be subsequently closed by a one way valve to keep the balloon inflated and allow additional inflation as desired, controllable by its tether.
