Device of reusable balloons

Abstract

The device of reusable balloons includes a rubber balloon and a base. The rubber balloon has a neck. After the balloon is inflated, the neck is twisted to form multiple tight spirals whose flexibility and pressure prevents air leakage, and the neck is tied into a loose single knot. The base has a first through hole and a second through hole arranged radially away from the base's center. A slit is provided connecting the first and second through holes that is selectively and flexibly opened. After the single knot is run through the first through hole, the neck is plugged into the second through hole through the slit. Four or more rubber balloons can be attached to the base and multiple bases can be coupled and arranged to decorate events. After the event, the single knot can be undone, allowing the balloon to deflate and be stored for repeated use.

I claim: 
     
         1 . A device of reusable balloons, comprising:
 a rubber balloon having a neck with an inlet through which air is pumped to inflate the rubber balloon, where, after the rubber balloon is inflated, the neck is twisted to form a plurality of tight spirals whose rubber flexibility exerts pressure to prevent air leakage, and the neck, along with the spirals, is tied into a loose single knot; and   a base having a flat circular or polygonal shape with a first through hole and a second through hole arranged radially in this order away from the base's center, a slit is provided connecting the first through hole and the second through hole that is selectively and flexibly opened to connect the first and second through holes, and, after the single knot is run through the first through hole, the neck of the rubber balloon is plugged into the second through hole through the slit.   
     
     
         2 . The device of reusable balloons according to  claim 1 , wherein a central through hole is provided at the center of the base for coupling the base with other bases. 
     
     
         3 . The device of reusable balloons according to  claim 2 , wherein the first through hole is positioned at an appropriate distance from the central through hole; and the first through hole has a diameter larger than that of the second through hole. 
     
     
         4 . The device of reusable balloons according to  claim 2 , wherein a third through hole is provided on the base between the second through hole and the base' rim; a gap connects the third through hole and the base's rim; and, the neck of the rubber balloon, after being slid into the second through hole, is bended and plugged into the third through hole through the gap.
