The liquid chemical fail can includes an inner container made of chemical-resistant synthetic resin and an outer container made of metal. The inner container is formed in a cylindrical shape and has an opening that can be opened to inject a liquid chemical. The outer container constitutes the outer shell of the inner container. The dispenser is connected to the opening of the fail can.

Moreover, the dispenser of the liquid chemical | medical agent which concerns on (1) is equipped with the cylindrical plug main body, the ventilation means, and the liquid transportation pipe of a dispenser. The plug body is fastened to the opening in a sealable manner. The ventilation means has an opening penetrating from the outside of the plug body toward the opening, and can pass the compressed fluid inside the inner container. One end of the liquid transport pipe reaches the bottom face of the inner container, the other end protrudes from the plug body, and is sealably mounted to the plug body. Then, the compressed fluid is pressurized to the air layer of the inner container through the venting means, so that the liquid chemical is discharged from the other end of the liquid transport pipe.

That the inner container is formed in a cylindrical shape includes a shape in which the inner container is formed in the shape of an employee column, and the inner container includes a shape in which the upper surface is formed in a trapezoidal trapezoidal shape whose area is larger than that of the bottom surface. In addition, that the inner container is formed in a cylindrical shape does not exclude that the opening is protruded from the upper surface of the inner container. The liquid chemical fail can does not necessarily exclude that the inner container is formed in a square cylinder shape. However, in order to resist deformation, such as the ease of manufacture of an inner side container, expansion by internal pressure, etc., a cylinder is preferable for an inner side container than a square cylinder.

The inner container made of chemical-resistant synthetic resin may be one made of a chemical-resistant synthetic resin, and can be mass-produced by plastic molding of the inner container. In addition, the inner container made of chemical-resistant synthetic resin means an inner container made of a synthetic resin in which a chemical contained in the inner container, that is, a chemical substance is in contact with the inner container and is difficult to chemically react with, for example, ions. .

One end of the liquid transport pipe reaches the bottom face of the inner container, the other end protrudes from the plug body, and is sealably mounted to the plug body. One end of the liquid transportation pipe may be cut obliquely, or an L-shaped joint (seam) may be connected to the other end of the liquid transportation pipe.

For example, the plug main body may comprise a coupling ring, a plug shell, and a seal ring. The coupling ring is screwed to the outer circumference of the opening. The plug shell is rotatably connected with the coupling ring. The seal ring is held inside the coupling ring and is in close contact with the end face of the opening to seal the ventilation of the boundary between the coupling ring and the plug shell. The plug shell may include a venting means and a first joint made of synthetic resin for fixing the liquid transport pipe so as to be detachably attached thereto, and since the plug shell is rotatably connected to the coupling ring, The supply port or the outlet of the liquid transport pipe can be arranged in any direction.
