Abstract

A self-contained, self-inflating balloon unit comprising a closed, inflatable balloon, a cannister containing compressed gas, at least partly inside the balloon, and a device for releasing the compressed gas from the cannister into the balloon to inflate the balloon. The balloon comprises an inflatable body portion and a neck portion, and the cannister is located in the neck portion. The cannister is preferably slidably mounted in a sleeve in the neck portion of the balloon. The sleeve includes a pin for rupturing the cannister when the cannister is urged against it. A one-way valve allows the gas to inflate the body portion but prevents its escape.

In some embodiments the unit also includes a tether which is connected at one end to the sleeve and at the other end to the cannister. After the balloon is inflated, the cannister can be removed from the sleeve, extending the tether. The empty cannister serves as a handle for the tether. The balloon and the cannister may be sized so that the empty cannister serves as an anchor for the balloon.

Claims

1. A self-contained, self-inflating novelty balloon unit comprising:

a closed, inflatable novelty balloon;

a canister containing compressed gas, entirely inside the balloon;

means for releasing the compressed gas from the canister into the balloon to inflate the balloon.

2. The balloon unit according to claim 1 wherein the cannister contains a lighter-than-air gas in sufficient quantity to make the entire balloon unit buoyant.

3. The balloon unit according to claim 1 wherein the balloon comprises an inflatable body portion and a neck portion, and wherein the cannister is located in the neck portion.

4. The balloon unit according to claim 3 wherein the cannister is contained entirely within the neck portion.

5. The balloon unit according to claim 3 further comprising a sleeve in the neck portion of the balloon in which the cannister can slide, the sleeve including means in the sleeve for rupturing the cannister to release the gas into the balloon when the cannister is urged against it.

6. The balloon unit according to claim 5 furhter comprising a one-way valve means on the sleeve that allows gas from the cannister to fill the body portion, but does not allow the gas to escape from the body portion.

7. The balloon unit according to claim 5 further comprising a plunger member, containing the cannister, telescopingly received in the sleeve for urging the cannister against the rupturing means.

13. The balloon unit according to claim 2 wherein the canister contains lighter-than-air gas in sufficient quantity to make the entire balloon unit buoyant.

8. A self-contained, self-inflating novelty balloon unit comprising:

a novelty balloon having an inflatable body portion and a neck portion;

a sleeve in the neck portion;

a canister containing compressed gas, slidably received in the sleeve, at least partly inside the balloon;

means in the sleeve for rupturing the canister to release the gas to inflate the balloon, when the canister is urged against it;

a tether connected at one end to the canister and at the other end to the sleeve, and contained between the canister and the sleeve, so that the canister can be separated from the sleeve after the balloon is inflated and used as a handle for the tether to retain the balloon.

9. The balloon unit according to claim 8 wherein the cannister is filled with a lighter-than-air gas, and wherein the balloon and the cannister are relatively sized so that the weight of the empty cannister is greater than the buoyant force of the inflated balloon, so that the empty cannister can anchor the balloon.

10. The balloon unit according to claim 8 further comprising a plunger member, containing the canister, telescopingly received in the sleeve for urging the canister against the rupturing means.

11. The balloon unit according to claim 10 wherein the canister is filled with a lighter-than-air gas, and wherein the balloon and the canister are relatively sized so that the weight of the plunger member and empty canister is greater than the buoyant force of the inflated balloon, so that the plunger member and empty canister can anchor the balloon.

12. A self-contained, self-inflating novelty balloon unit comprising:

a novelty balloon having an inflatable body portion and a neck portion;

a sleeve in the neck portion;

a canister containing compressed gas slidably received in the sleeve, entirely inside the balloon;

means in the sleeve for rupturing the canister to release the gas to inflate the balloon, when the canister is urged against it.

14. The balloon unit according to claim 12 wherein the cannister is enclosed with the balloon.

15. The balloon unit according to claim 12 further comprising a one-way valve means on the sleeve that allows gas from the cannister to fill the body portion, but does not allow the gas to escape from the body portion.

16. The balloon unit according to claim 12 further comprising a plunger member, containing the cannister, telescopingly received in the sleeve for urging the cannister against the rupturing means.

17. The balloon unit according to claim 16 further comprising a tether connected at one end to the plunger member and at the other end to the sleeve, and contained between the plunger member and the sleeve, so that the plunger member can be separated from the sleeve after the balloon is inflated and used as a handle for the tether to retain the balloon.

18. The balloon unit according to claim 17 wherein the cannister is filled with a lighter-than-air gas, and wherein the balloon and the cannister are relatively sized so that the weight of the plunger member and empty cannister is greater than the buoyant force of the inflated balloon, so that the plunger member can anchor the balloon.
