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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0016] As shown in FIGS. 1 and 2, a device of reusable balloons according to an embodiment of the present invention includes a rubber balloon and a base 13.

[0017] The rubber balloon has an elongated neck with an inlet at an end away from the rubber balloon, where the rubber balloon is inflated by pumping air into the rubber balloon through the inlet. The neck is then twisted a number of times to form multiple tight spirals 11. With the pressure exerted from the rubber flexibility of spirals 11 to prevent air leakage, an anti-leak effect is achieved. A single knot 12 is then tied at the neck that can be easily untied. In short, the single knot 12 is a loosely tied knot, allowing the rubber balloon to maintain its inflation without air leakage. After use, the single knot 12 can be easily untied to release the air, restoring the rubber balloon to its relaxed state for reuse.

[0018] As shown in FIG. 3, the base 13 has a flat circular or polygonal shape. The base 13 has pairs of a first through hole 14 and a second through hole 16. Each pair of the first through hole 14 and the second through hole 16 are arranged radially in this order away from the center of the base 13. A slit 15 is provided connecting each pair of the first through hole 14 and the second through hole 16. The slit 15 can be selectively and flexibly opened or closed. The single knot 13 may run through the first through hole 14. When the slit 15 is opened, the neck may enter the second through hole 16.

[0019] In other words, one or more rubber balloons can be fixed to the base 13 and, by stacking a number of bases 13 together, the rubber balloons can jointly form a designed form

[0020] A central through hole 18 is provided in the center of the base 13. The central through hole 18 is configured with a connection element (not shown) for coupling with another base 13. The first through holes 14 are positioned surrounding the central through hole 18 at an appropriate distance. The first through holes 14 have a diameter larger than that of the second through holes 16.

[0021] As disclosed above, the present invention relies on the spirals 11 on the rubber balloon's neck to prevent its air leakage. The neck is then tied into a loose single knot 12 that can be easily untied to reuse the rubber balloon. Then, the positioning of the rubber balloon is achieved by fixing it to the bases 13.

[0022] In an alternative embodiment of the present invention, a third through hole 17 is provided on the base 13 between each second through hole 16 and the rim of the base 13. Each of the third through holes 17 has a gap (not numbered) connecting the third through hole 17 to the rim of the base 13. As such, the neck of the rubber balloon, after being slid into a second through hole 15, can be bended and plugged into a third through hole 17 through the gap for more reliable positioning.

[0023] More specifically, as shown in FIGS. 2 and 3, the single knot 12 of a rubber balloon's neck is first run through a first through hole 14. The neck of the rubber balloon is then pulled into a second through hole 16 through the slit 15 between the first and second through holes 14 and 16. By repeating the above process to fix additional balloons, a device 10 of reusable balloons is achieved. In the alternative embodiment, these balloons' necks can be further bended into the third through holes 17.

[0024] Multiple sets of bases 13, along with the rubber balloons attached to the bases 13, can be coupled and arranged to form objects of various shapes, such as the clown-shaped object shown in FIG. 4.

[0025] While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
