This is to attach an object with a large inertial mass to the lid support 142 of the closure means that is moved by a sudden impact to absorb the force generated when the closure means 14 open.

That is, according to Newton's second law of motion, the force can be expressed as the product of the inertia mass and the acceleration, and the large inertia mass absorbs the force generated when the sealing means 14 is opened, thereby reducing the small acceleration. Since the velocity due to the pressure at the time of opening becomes smaller, the velocity change becomes smaller from the stationary state, and the impact amount expressed by the product of the mass and the velocity change becomes smaller.

In addition, when the sealing means 14 is opened from the pressure vessel 13, the sealing means 14 is a rotational movement around the lower shaft pin (146). Thus, the force received by the closure means 14 being opened is represented by the moment by rotation. Therefore, it is preferable to attach the shock absorbing member 16 to a position capable of absorbing the most generated moment.

At this time, since the position where the moment can be most absorbed is the position farthest from the lower shaft pin 146 which is the rotation center, the buffer member 16 is located near the upper eye 144 on the lid support 142. It will be desirable to form a weight attached to the.

In addition, since the shock absorbing member 16 may be absorbed while hitting the floor or another predetermined structure, the shock absorbing member may be curved so that the outer circumferential surface thereof may be curved to increase the contact area as much as possible to absorb the shock. It would be desirable to make the shape of 16).

The splash apparatus according to the present invention, as described above, the buffer member 16 is formed of a weight attached to the position farthest from the lower shaft pin, and applied to the pressure vessel and the lid without the need for additional external device when opening the lid. It can alleviate the impact of losing.

In addition, the buffer member 16 has an outer circumferential surface of the curved surface to absorb the shock well even when the shock absorbed by the contact.

According to the splash apparatus of the present invention, the pressure vessel can be automatically opened with respect to the set pressure.

In addition, the impact on the pressure vessel and the lid can be alleviated without the need for additional external devices upon opening the lid.
