| مستخلص: | A balloon device includes an inner container and an outer container that are movable with respect to each other. The device includes a pressurized gas container mounted in the inner container and a firing mechanism that is operated by slamming the device against a solid surface such as a table top or the like. The firing mechanism punctures the pressurized container and permits gas to escape into the device, and this gas is guided via orifices to the balloon that is sealingly held on the device by an O-ring type element. When the balloon is pressurized to a prescribed pressure, further pressurization of the device will move the inner container and the surface against which the O-ring seats disappears as the inner container moves with respect to the outer container. The balloon is released and sealed as the O-ring is released. |

| Claim: | We claim |
| Claim: | 1. A balloon inflating device comprising |
| Claim: | an outer container having a bottom and a side wall and having a hole defined in said bottom, said side wall having a height and a top edge; |
| Claim: | an inner container having a bottom and a side wall and having a hole defined through said inner container bottom to be aligned with the hole in said outer container bottom, said inner container side wall having a height which is less than said outer container wall height and a top edge, said inner container bottom being smaller than said outer container bottom and said inner container being mounted within said outer container to slide within said outer container from a first position with said inner container side wall extending above said outer container side wall to a second position with said inner container side wall top edge being no higher than co-level with said outer container top edge with respect to said outer container bottom; |
| Claim: | a pressurized fluid container located within said inner container and including a rupturable wall; |
| Claim: | mounting means mounting said pressurized fluid container on said inner container for movement therewith; |
| Claim: | fluid passage means on said mounting means for conducting pressurized fluid past said pressurized fluid container out of said inner container; |
| Claim: | rupturing means slidably mounted on said inner and outer container through said aligned holes and including a head located beneath said outer container bottom and a point located adjacent to said pressurized fluid container rupturable wall, said rupturing means being movable from a cocked position having said point spaced from said rupturable wall to a rupturing position having said point puncturing through said rupturable wall; |
| Claim: | sealing means on said rupturing means for sealingly covering said inner container hole; |
| Claim: | biasing means on said rupturing means and having one end thereof mounted on said rupturing means and another end thereof engaging said inner container bottom and biasing said inner container toward said first position and said rupturing means towards said cocked position; and |
| Claim: | balloon closing means located to capture a balloon against said inner container side wall closely adjacent to said inner container side wall top edge and seal said balloon against said inner container side wall and against said outer container side wall when said inner container is in said first position. |
| Claim: | 2. The balloon inflating device defined in claim 1 wherein said mounting means includes means releasably mounting said pressurized fluid container on said inner container. |
| Claim: | 3. The balloon inflating device defined in claim 2 wherein said rupturing means includes a needle. |
| Claim: | 4. A method of inflating a balloon comprising |
| Claim: | providing the device defined in claim 1; |
| Claim: | placing the pressurized container in the inner container; |
| Claim: | placing a balloon on the device; |
| Claim: | sealing the balloon against the inner container using the sealing means; |
| Claim: | impacting the head of the rupturing means against a solid surface and driving that rupturing means from the cocked position to the rupturing position; |
| Claim: | withdrawing the rupturing means from the pressurized fluid container to open a hole in that pressurized fluid container; |
| Claim: | permitting fluid from the pressurized container to flow out of the pressurized container; |
| Claim: | guiding the pressurized fluid from the pressurized container around the pressurized container into the balloon via the fluid passage means; |
| Claim: | filling the balloon to a prescribed pressure; |
| Claim: | continuing to permit gas to escape from the pressurized container and applying gas pressure-induced force against the bottom of the inner container in a direction opposite to the bias exerted by that biasing means; |
| Claim: | forcing the inner container bottom toward the outer container bottom and moving the inner container wall downwardly with respect to the outer container wall until the inner container is in the second position; and |
| Claim: | releasing the balloon and the balloon closing means. |
