[Work]

The above-described embodiment is used by being attached to the mouth of a helium gas cylinder, for example.

In the first embodiment, when the balloon (53) is attached to the cylinder, the protrusion (36) is first engaged with the elevated step (37) by pressing and turning the knob (34). Nozzle connecting mouth
(4) is inserted and fitted, and both sides of the connecting nozzle (54) are clamped with the fingers of the right hand on the outside of the mouth of the balloon (53), and the connecting nozzle (54) is held in this clamped state by the third coil spring. It is pushed against the action force of (50), so that the helium gas is decompressed from the cylinder by the pressure reducing valve (21) and then passes between the peripheral wall of the narrow path (30) and the outer peripheral surface of the narrow rod (29). A large amount is supplied from the connecting nozzle (54) (see FIG. 1) to rapidly inflate the balloon (53), and when the inflated state reaches a desired (limit) size, the knob ( 34) is turned back in the opposite direction to engage the projection (36) with the lower stepped portion (38), so that the ball valve element (31) is located in the narrow path (30). (See Fig. 2) and supply a small amount of gas from the connecting nozzle (54), and
Inflate 3) at a slow speed to the desired size (up to or near the limit), and when it reaches this size, close the neck of the balloon (53) with the fingers of the left hand and close the balloon (53) with the connecting nozzle ( The second embodiment is to be connected to the mouth of the balloon (53) by pressing the mouth of the balloon (53) tightly against the mouth of the auxiliary nozzle (57) with fingers when attaching to the cylinder. At the same time, the auxiliary nozzle (57) and the connecting nozzle (54) are pushed by the force of the finger against the acting force of the third coil spring (50), so that the helium gas is released from the cylinder into the pressure reducing valve (2
After being decompressed by 1), a large amount is supplied through the mouth of the auxiliary nozzle (57) (the mouth of this auxiliary nozzle (57) is not crushed at this time) (see FIG. 4) and the balloon (53) is rapidly supplied. The auxiliary nozzle (57) with the fingers pressing the mouth of the balloon (53) against the mouth of the auxiliary nozzle (57) when the bulge state reaches the desired size. By narrowing the mouth by squeezing it from both sides to reduce the gas supply amount, the balloon (53) is slowly inflated to a desired (limit or near) size at a slow speed, and when this size is reached, Close the mouth of the balloon (53) by moving the fingers pressing against the mouth of the balloon (53) so as not to cause gas leakage, and then open the mouth of the balloon (53) of the auxiliary nozzle (57). It is used in a way that it can be quickly removed from the mouth. After inserting the mouth of the balloon (53) into the connecting nozzle (64) and fitting it, press the push button (59) to open the on-off valve (61), and the helium gas from the cylinder is reduced by the pressure reducing valve (21). And the low pressure regulator (63) reduces the pressure in two steps (up to about 280 mm / H ₂ O) and supplies it to the balloon (53).
3) is inflated and the internal pressure of the balloon (53) is reduced to two levels (about 28
When it reaches 0 mm / H ₂ O), the gas supply is automatically stopped,
When this stop is confirmed, the pressing operation on the push button (59) is canceled to close the open / close valve (61), and after this closing, the balloon is closed.
It is used in a manner such as removing (53) from the connecting nozzle (64).

The above-mentioned first and second embodiments are those in which the balloon is inflated rapidly at the beginning and the balloon is inflated at the end, that is, it is difficult for the balloon to be inflated, which is particularly difficult. When taking the timing to remove the balloon in the final stage, it can be inflated slowly so that even an amateur can perform the above work without failure, and in the third embodiment, the balloon (53)
Since it can only inflate to a two-step decompression value (about 280 mm / H ₂ O), even an amateur can complete the balloon inflating work without any failure as long as the balloon (53) is not damaged.

In particular, the third embodiment is most suitable for use in a balloon made of a synthetic resin film, which is generally called a UFO balloon.
