Abstract

A plug and light stick allow a light bulb to be positioned within a common elastic expandable inflatable balloon having an elastic filler neck. The plug fits into the neck of a balloon and seals against the neck wall. The plug has a central bore having an interior end located within the balloon neck and an outer end. The light stick includes an elongated cylindrical tube having a light bulb on the insertion end. The bore contains therein at least one concentric constriction ring and the tube has an outside diameter such that the tube forms a sliding air-tight seal with the constriction ring when inserted in the bore. A pair of electric conductors extend from the bulb, pass along the interior of the tube external the balloon, and connect to an electrical energy source for lighting the balloon. The method involves inserting the plug into the elastic filler neck of the balloon, inflating the balloon by injecting gas through the bore, sealing off the neck interior to the plug, inserting the bulb end, including bulb 35, of the light stick into the exterior end of the plug bore, and positioning the bulb within the balloon as desired.

Claims

1. A balloon lighting device comprising, in combination:

an inflatable balloon having an elastic neck portion and an interior;

a plug adapted for a pneumatically tight-fit inside said neck and having a bore formed therethrough for access to the interior of said balloon;

a hollow tube having an interior and having spaced-apart terminal ends of an outside diameter forming a sliding air-tight seal with said bore when inserted through said bore; and

,

a light bulb attached to one terminal end of said hollow tube in pneumatic sealing relationship therewith for positioning inside said balloon and including a pair of electric conductors passing from said balloon along the interior of said tube external said balloon.

2. The balloon lighting device of claim 1 further including an electric energy source for connection to said conductors to generate light in said bulb inside said balloon.

3. The balloon light device of claim 9 wherein said hollow tube is elongated and attached to said energy source and of sufficient rigidity to support said balloon spaced above said source.

4. The device of claim 8 wherein said plug bore includes at least one concentric constriction ring interior thereof and said cylindrical member outside diameter forms a sliding seal with said ring.

5. The balloon lighting device of claim 1 wherein said plug includes a planar member having a circumference larger than said neck for transverse positioning in said balloon neck to form a pneumatic seal therebetween.

6. The balloon lighting device of claim 5 wherein said planar member is a thin disk.

7. The balloon lighting device of claim 6 wherein said disk is circular.

8. The balloon lighting device of claim 6 wherein said bore is formed by a short hollow stub extending from an aperture formed in said planar member, normal thereto.

9. The balloon lighting device of claim 6 wherein said bore is formed by a short hollow stub extending from an aperture formed central in said disk, normal thereto.

10. The balloon lighting device of claim 6 wherein said bore is formed by a pair of short hollow stubs in mutual alignment and extending from opposite sides of an aperture formed in said planar member, normal thereto.

11. The balloon lighting device of claim 6 wherein said bore is formed by a pair of short hollow stubs in mutual alignment and extending from opposite sides of an aperture formed in said disk, normal thereto.

12. A device for lighting an interior of an inflatable balloon having an elastic neck portion, comprising:

a plug adapted to form an air-tight seal between said plug and the balloon neck when placed inside the elastic neck of the balloon and having a bore formed therethrough for access to the interior of the attached balloon;

said bore including an interior end for disposition inside the balloon neck and an exterior end; and

a light stick including;

an elongated cylindrical member having an insertion end and having an outside diameter of such size as to form a sliding air-tight seal with said plug bore;

a light source attached to said insertion end of said cylindrical member;

said light source of a size for fitting through said bore; and

electrical conductor means within said cylindrical member and contacting said light source for conducting electricity for lighting said light source.

13. The device of claim 12 further including an electric energy source for connection to said conductor means to generate light in said bulb inside said balloon.

14. The device of claim 12 wherein said plug bore includes at least one concentric constriction ring interior thereof and said cylindrical member outside diameter forms a sliding seal with said ring.

15. The device of claim 12 wherein said plug includes a planar member having a circumference larger than the balloon neck for transverse positioning in the balloon neck to form an air-tight seal therebetween.

16. The device of claim 15 wherein said planar member comprises a thin, circular disk.

17. The device of claim 15 wherein said bore is formed by a short, hollow stub extending from an aperture formed in said planar member, normal thereto.

18. The device of claim 15 wherein said bore is formed by a pair of short, hollow stubs in mutual alignment and extending from opposite sides of an aperture formed in said planar member, normal thereto.

19. A method of inserting a light source into an inflatable balloon having an elastic filler neck such that the light source is positionable within the inflated balloon comprises the steps of:

inserting a plug into the elastic filler neck of an inflatable balloon;

the plug adapted to form an air-tight seal between the neck of the balloon;

the plug having a bore therethrough for access to an interior of the balloon;

the bore having an interior end for disposition within the balloon neck and an exterior end;

inflating the balloon by injecting gas through the plug bore;

then sealing the neck such that fluid communication is sealed off between the interior of the inflated and plugged balloon and the interior end of the plug bore;

then inserting a light stick into the exterior end of the plug bore so as to substantially seal the bore;

the light stick comprising an elongated cylindrical member having an insertion end and having an outside diameter of such size as to form a sliding air-tight seal with the plug bore and comprising a light source attached to the insertion end of the cylindrical member;

the light source of a size for fitting through said bore; and

then releasing the neck seal and restoring fluid communication between the balloon interior and the interior plug bore; and

then sliding the light stick within the bore so as to place the light source at a desired position within the inflated balloon.

20. The method of claim 19 wherein the inserted light stick includes electrical conductor means within the cylindrical member and contacting said light source for conducting electricity for lighting said light source.
