DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment of the present invention shown in FIGS. 1 to 7, the container body is the same as the conventional one, so that the description thereof will be omitted. 1 and 2 show a lower end portion of a cap 1, a cylindrical portion 2 is provided on one side of the lower end of the cap 1, and a plug 3 is attached to the cylindrical portion 2.
The base portion 4 is fitted and fixed, and a front portion 6 of the base portion 4 projects from the inner periphery of the cap 1, and a first magnet 7 is provided on the front portion 6.

FIGS. 3 and 4 show a neck 8 to which the lower end of the cap 1 is fitted. The neck 8 is provided with a locking hole 11 consisting of a downward opening 9 and a circumferential blind hole 10 connected to one side surface of the opening 9, and a side surface of the opening 9 of the neck 8 opposite to the blind hole 10. A second magnet 12 is provided at the end of the blind hole 10 and a third magnet 12
13 are provided. A non-magnetic portion is provided above and below the first magnet 7.
14, 15 and non-magnetic portions 16, 17 above and below the second magnet 12
Further, a nonmagnetic portion 18 is provided on the surface of the opening 9 opposite to the nonmagnetic portion 16, and nonmagnetic portions 19 and 20 are provided above and below the third magnet 13.

The polarities N and S of the first magnet 7 are different on the second magnet 12 side and on the opposite side, and
The polarities S and N of the magnet 12 are different on the first magnet 7 side and the opposite side, and the polarity S on the first magnet 7 side is the first polarity.
The polarity N of the third magnet 13 is different from that of the third magnet 13 on the opposite side, and the polarity N of the third magnet 13 is different from the polarity S of the third magnet 13. The polarity is opposite to the polarity S of the first magnet. In this device, the two polarities N, S of the magnets 7, 12, 13 are opposite polarities S, N, respectively.
It may be. In the first, second, and third magnets, the first, second, and third axes A, B, and C are the plugs 3 shown in FIGS.
As shown in FIG. 7, the first axis A is located at the intermediate height between the second and third axes B and C at the bottom of the locking hole 11.

A description will be given of a state where the cap 1 is mounted on the neck 8 in the above-described configuration. As shown in FIG. 5, the cap 1 is fitted on the neck 8, and the front part 6 of the plug 3 is fitted into the opening 9 of the locking hole 11 of the neck 8 and pressed down. When the plug 3 reaches the bottom surface of the locking hole 11 as shown in FIG. 6, the cap 1 is rotated in the direction of the blind hole 10 of the neck 8 to move the plug 3 through the blind hole 10. When the plug 3 reaches the end of the blind hole 10 as shown in FIG. 7, the mounting of the cap 1 on the neck 8 is completed.

As described above, when the cap 1 is moved, the first, second, and third magnets are arranged such that the first, second, and third axes are at the positions A, B, and C, respectively. Therefore, when the plug 3 descends through the opening 9 of the neck 8 as shown in FIG. 5 and reaches the bottom surface of the locking hole 11 as shown in FIG. Of the same polarity S
Therefore, the plug 3 repels each other and acts on the plug 3 in the direction of the arrow ft to facilitate rotation of the plug 3, that is, the cap 1. When the plug 3 moves near the end point of the blind hole 10, since the polarities of the first and third magnets are different polarities S and N, the rotation of the plug 3, that is, the cap 1, is facilitated by the suction action. And at the end of the blind hole,
The three magnets are attracted and the cap 1 is firmly connected to the neck 8 so that the cap 1 does not come off unintentionally.
It is securely held by the neck 8.

When removing the cap 3 from the neck 8, the cap 1 is turned in the opposite direction to move the plug 3 in the blind hole 10 in the opposite direction, and then is raised in the opening 9. However, during this ascent, the repulsive force of the same pole S of the first and second magnets 7, 12 exerts a force in the direction of arrow fu shown in FIG.

Since the non-magnetic portions 14, 15, 16, 17, 18, 19, and 20 are provided during the operation as described above, the first, second, and third magnets 7, 12, and 13 are provided. The thirteen acting forces are effectively exhibited without waste.

[0015]

The present invention is as described above. In the high-pressure gas container, the invention according to claim 1 is characterized in that the neck has a radial opening and a circumferential blind hole connected to one side of the opening. And a plug is provided at a position of the cap facing the locking hole. The plug is fitted into the opening of the neck when the cap is fitted to the neck, and the cap is connected to the blind of the neck. When turning in the direction of the hole,
The cap is connected to the neck by moving in the blind hole, a first magnet is provided on the plug, and a second magnet is provided on a side of the opening of the neck opposite to the blind hole. The third magnet is provided at the end of the blind hole, so that the cap can be easily removed and attached at the time of filling or discharging the gas, and the mounting is completely performed. .

According to a second aspect of the present invention, in the first aspect, the polarity of the first magnet is different between the second magnet side and the opposite side. The polarities of the two magnets are different between the first magnet side and the opposite side, the polarity of the first magnet side is the same as the polarity of the first magnet, and the polarity of the third magnet is The first magnet side and the opposite side have different polarities, and the polarity of the first magnet side is opposite to the polarity of the first magnet.
Non-magnetic portions are provided on the upper and lower sides of the magnet and on one side surface of the opening. The first, second and third magnets have their first, second and third axes aligned with the plug located on the bottom surface of the locking hole. Then, the first
Since the axis is arranged at an intermediate height position between the second and third axes, when the worker inserts the plug into the locking hole and turns the cap to attach the cap to the neck,
The movement is smoothly performed by a slight force due to both the repulsive force and the attractive force generated by the difference in polarity between the first magnet provided on the plug and the second and third magnets provided on the neck. Further, there is an effect that the plug is securely held on the neck when the plug is attached to the neck of the cap.
