Embodiments of the present invention will be described below with reference to the drawings.

First, FIGS. 1 and 2 show a first embodiment of a portable small cylinder, in which 1 is a size that can be stored in a palm, for example, a spherical shape having a diameter of about 20 to 80 mm. And a small cylinder body, the cylinder body 1
An opening 11 is formed in the. This cylinder body 1 has two bowl-shaped members 12 and 13 formed in a hemispherical shape and made of stainless steel or aluminum having a plate thickness of about 1 to 3 mm, but is welded to each other in a so-called hollow shape, or has a plastic material inside. This is a closed pressure-resistant container formed into a hollow spherical shape.

A seat 2 having a screw hole 21 is attached and welded to the opening 11 of the cylinder body 1, and a part of the plug 3 is screwed into the screw hole 21 of the seat 2. A communication hole 32 having an ejection port 31 at one end is formed in the plug body 3, and the other end of the communication hole 32 faces the inside of the cylinder body 1. Therefore, the ejection port 31 is substantially connected to the cylinder body 1. It is a jet outlet provided. Further, a communication pipe 33 and a thin pipe 34 are provided on the side of the communication hole 32 facing the inside of the cylinder body 1.
Is provided to prevent the high pressure nitrogen gas from directly ejecting from the ejection port 31 due to a pressure drop when ejecting the high pressure nitrogen gas contained in the cylinder body 1 from the ejection port 31. .

The valve seat 4 is provided in the middle of the communication hole 32 of the plug body 3.
1, a valve mechanism 4 including a ball valve 42, a spring 43, a valve rod 44 having an operating portion 45, and a spring 46 is provided.
