Abstract

A system and method for simultaneously inflating a plurality of balloons with pressurized gas issuing from a pressurized gas supply, each balloon being releasably or permanently attached to an inflation conduit which serves to duct gas from the gas supply to its respective balloon, and each balloon having an associated valve to control the release of gas from inside the balloon when connected and/or disconnected from its associated balloon.

Claims

1. A balloon for use in a system for inflating balloons with pressurized gas issuing from a pressurized gas supply, said balloon comprising an inflatable body with a neck region defining an opening of the inflatable body through which pressurized gas can pass to inflate the balloon,

and wherein said balloon is connectable to an inflation conduit that is adapted to duct pressurized gas from the pressurized gas supply to said inflatable body,

and wherein said balloon comprises a valve configurable between an open condition to permit the entry of gas to the inflatable body via the inflation conduit and a closed condition to restrict the egress of gas from said inflatable body via the inflation conduit, said valve being located inside the inflatable body,

and wherein at or adjacent the opening at least a first portion of an interior surface of the neck region is bonded to itself forming at least one bonded region to the seal the opening, save for a passage leading from the opening into the neck region.

2. The balloon of claim 1 wherein either:

a) the opening is sealed with a single bonded region, save for the passage leading from the opening into the neck region;

or

b) a portion of an interior surface of the neck region is bonded to itself forming a first bonded region, and wherein a further portion of the interior surface of the neck region is bonded to itself forming a second bonded region, and wherein the first and second bonded regions together seal the opening, save for the passage leading from the opening into the neck region, the first and second bonded regions being located on either side of the passage.

3. The balloon of claim 1 wherein the width of the passage is less than ½

of the width of the opening and optionally less than ¼

of the width of the opening.

4. The balloon of claim 1 wherein the bonded region(s) has/have a flat profile.

5. The balloon of claim 1 wherein at the bonded region(s) said interior surface of the neck region is bonded directly onto itself.

6. The balloon of claim 1 wherein said valve is located at the opening of the inflatable body, inside of the neck region, and bonded to the neck region at at least one of said bonded regions.

7. The balloon of claim 1 wherein the bonded region(s) has/have been formed by pressing or pinching the neck region with the valve in situ.

8. The balloon of claim 1 wherein said valve is a one-way valve that adopts a substantially flat profile in the closed condition.

9. The balloon of claim 8 wherein the valve is duckbill valve comprising two plies of flexible sheet material joined with one another in a manner to define a sealable passage therethrough.

10. The balloon of claim 1 wherein the valve includes a connector to releasably connect with the inflation conduit.

11. The balloon of claim 10 wherein the connector is adapted to releasably engage with the first end of the inflation conduit at an engagement region,

and wherein the connector is located at least partially inside a sealable passage of the valve with the engagement region projecting out of a first end of said passage, and wherein the plies of the valve are sealed around the exterior of the connector, and wherein the sealable passage of the valve is able to collapse at a second end so as to seal the passage about an end of the connector opposing the engagement region.

12. The balloon of claim 10 wherein said connector extends through the passage at the neck region of the inflatable body, and wherein at least a second portion of the interior surface of the neck region, said second portion being a portion that defines the passage, is bonded to the connector.

13. The balloon of claim 1 wherein said balloon has a permanently attached flexible tether of elongate cord or strip form.

14. The balloon of claim 1 wherein said inflatable body is made of an elastically expandable material.

15. A balloon assembly for use in a system for inflating balloons with pressurized gas issuing from a pressurized gas supply, comprising a balloon as claimed in claim 1 and an inflation conduit connected to said balloon.

16. A system for simultaneously inflating a plurality of balloons comprising a plurality of balloon assemblies as claimed in claim 15, wherein each one of the plurality of balloon assemblies is joined with at least one other balloon assembly by a severable connection between their respective inflation conduits.

17. A method of simultaneously inflating a plurality of balloons with pressurized gas issuing from a pressurized gas supply via a plurality of inflation conduits,

each of said inflation conduits being configured to duct pressurized gas from the pressurized gas supply to a respective one of the balloons, said method employing a plurality of balloon assemblies as claimed in claim 16,

wherein said method comprises the steps of:

a) providing the plurality of balloon assemblies, each in fluid communication with the pressurized gas supply via a respective one of the inflation conduits; and

b) simultaneously inflating the balloons with pressurized gas.

18. The method of claim 17 wherein the method further comprises one or more steps selected from:

a) connecting the inflation conduits to be in fluid communication with the gas supply;

b) releasing the inflation tubes from fluid communication with the gas supply; and

c) re-connecting one or more of the inflation conduits to be in fluid communication with the gas supply.

19. The method of claim 17 wherein the method further comprises one or more steps selected from:

a) connecting the balloons with the inflation conduits;

b) disconnecting the balloons from the inflation conduits; and

c) re-connecting one or more of the balloons with respective ones of the inflation conduits.

20. The method of claim 17 wherein the method further comprises the step of tethering or anchoring one of more of the balloons using one or more selected from:

a) a tether connected to the balloon;

b) an inflation conduit; and

c) a connector of the balloon which is adapted to connect to both of the inflation conduit and an corresponding connector of a balloon support surface or frame.
