Abstract

A balloon valve assembly for use in inflating balloons which contains a tube portion with a passageway, and a head portion adapted for insertion into the neck of an inflatable balloon which has a bottom wall forming a flange, an orifice through the bottom wall, and a side wall extending from the bottom wall and defining a substantially non-circular outer surface of the head portion. A valve flap member is mounted to the bottom wall of the head portion for sealing the orifice in the bottom wall.

Claims

1. A balloon valve assembly for use in inflating balloons, the balloon valve assembly comprising:

(a) a tube portion including a passageway therethrough, a first free end, and a second free end;

(b) a head portion adapted for insertion into the neck of an inflatable balloon, said head portion being connected to said second end of said tube portion and having a bottom wall forming a flange to said second end, an orifice through said bottom wall communicating with said passageway, and a side wall extending from said bottom wall and defining a substantially non-circular outer surface of said head portion, wherein said non-circular outer surface has a cross-sectional shape defined by a major axis and a minor axis, and wherein the ratio of the length of said major axis to the length of said minor axis is at least 1.2; and

(c) a valve flap member mounted to said bottom wall for sealing said orifice in said bottom wall.

2. The balloon valve assembly of claim 1 wherein said non-circular outer surface of said head portion has a continuously arcuate shape.

3. The balloon valve assembly of claim 1 wherein said outer surface of said head portion includes first and second side wall sections, said first side wall section having a cross-dimension greater than that of said second side wall section.

4. The balloon valve assembly of claim 1 wherein said side wall defines a recess about said orifice.

5. The balloon valve assembly of claim 1 wherein said orifice in said bottom wall is generally circular.

6. The balloon valve assembly of claim 1 including a first valve flap member mounting post formed integrally with said bottom wall and adjacent said orifice.

7. The balloon valve assembly of claim 1 wherein said first free end of said tube portion has a generally cylindrical outer surface and includes an inwardly tapered internal bore for fitting sealingly onto various types and sizes of nozzles of balloon gas filling apparatus.

8. The balloon valve assembly of claim 1 wherein said valve flap member consists essentially of a film material selected from the group consisting of polypropylene, polyethylene, vinyl acetate, and nylon.

9. The balloon valve assembly of claim 1 wherein said valve flap member consists of photographic film base material.

10. The balloon valve assembly of claim 1 wherein said valve flap member consists of a film material having a thickness of from about 0.004 to about 0.012 inches.

11. The balloon valve assembly of claim 1 wherein said non-circular outer surface of said head portion is elliptical.

12. The balloon valve assembly of claim 1 wherein the shape of said non-circular outer surface of said head portion has a a first maximum cross-dimension and a second minimum cross-dimension different from said first cross-dimension.

13. The balloon valve assembly of claim 1 wherein said non-circular outer surface of said head portion is substantially oval.

14. The balloon valve assembly of claim 3 wherein said second side wall section is narrower than said first side wall section and said first and second side wall sections are located so that upon insertion into the neck of a balloon said second narrower flange section is in sealing contact with the bead of the neck of said balloon, and said first side wall section is in sealing contact with said neck of said balloon.

15. The balloon valve assembly of claim 4 wherein said recess is non-circular.

16. The balloon valve assembly of claim 6 including a second valve flap member mounting post, said second valve flap member mounting post being located substantially opposite said first flap member mounting post.

17. The balloon valve assembly of claim 12 wherein said first cross-dimension is greater than said second cross-dimension, and the ratio of said first cross-dimension to said second cross-dimension is from about 1.2 to about 1.8.

18. The balloon valve assembly of claim 17 wherein said ratio is from about 1.4 to about 1.5.

19. The balloon valve assembly of claim 1 wherein at least one side of said valve flap member is coated with a substantially non-toxic lubricant.

20. The balloon valve assembly as recited in claim 1 including staple means for securing a tether to said assembly and wherein crimped staple legs are disposed within said tube portion.

21. The balloon valve assembly as recited in claim 1 including a series of axially extending tapered ribs on the interior wall of said tube portion disposed between said first free end and said second end.

22. The balloon valve assembly as recited in claim 6, wherein said first valve flap member mounting post has a cross-sectional shape which varies from its top to its bottom.

23. A balloon assembly comprised of a first balloon valve assembly as recited in claim 1 and a second balloon valve assembly as recited in claim 1, of said first and said second balloon valve assemblies being comprised of a head portion and a tube portion and is connected to an inelastic bag with an external surface, and wherein:

(a) said head portion of said first balloon valve assembly is connected to said inelastic bag,

(b) said tube portion of said first balloon valve assembly is situated outside of said inelastic bag,

(c) said tube portion of said second balloon valve assembly is removably connected to said inelastic bag,

(d) said balloon valve assembly is further comprised of an elastic balloon which is mounted on said head portion of said second balloon valve assembly,

whereby fluid introduced through said tube portion of said first valve assembly enters and distends said inelastic bag, and whereby when external pressure is applied to said external surface of said inelastic bag fluid within said inelastic bag is discharged through said second balloon valve assembly and into said elastic balloon.
