Therefore, the canister can according to Patent Document 1 is a container excellent in so-called residual liquid property, in which the liquid medicine is hardly left in the container. On the other hand, the pail can has a problem that the bottom surface is flat and the liquid transportation tube is assembled so as to be positioned at the peripheral edge of the bottom surface, so that the liquid medicine easily remains in the container. There is a need for an apparatus for dispensing liquid medicines having excellent balance characteristics, in which liquid medicines do not remain in the pail cans for liquid medicines. The above is a problem of the present invention.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a pail for liquid medicine which can be manufactured at a low cost, a dispensing apparatus and a dispensing apparatus And a method thereof.

The present inventor has found out that the dispenser can be easily and easily configured by forming the container for liquid medicine into a double-structure pail can surrounded by the inner container made of molded synthetic resin and the outer container made of metal, and based on this, A new liquid medicine dispensing apparatus and dispensing method has been invented.

(1) A pail for liquid medicine comprising: an inner container made of a natural soft synthetic resin having an opening that is formed in a tubular shape and openable for injecting a liquid medicine, and a metal outer container constituting an outer periphery of the inner container; And a dispenser connected to the opening portion of the fail can, wherein the dispenser includes: a cylindrical plug body sealingly fastened to the opening portion; and a through-hole extending from the outside of the plug body toward the opening portion, And the other end is protruded from the plug body, and the plug body is sealably mounted on the plug body. The plug body has an opening for allowing the pressurized fluid to pass through the inside of the inner vessel. And a liquid transport pipe which is connected to the inner container through the air supply means, Body is being pressed, the liquid drug when a dispensing device for liquid medication that is discharged from the other end of the fluid transport pipe.

The liquid medicine dispensing apparatus according to the invention of (1) comprises a pail for liquid medicine and a dispenser.

The inner container is formed in a cylindrical shape and has an opening that allows the liquid medicine to be injected. The outer container constitutes the outer periphery of the inner container. The dispenser is connected to the opening portion of the fail can.

In the liquid medicine dispensing apparatus according to the invention of (1), the dispenser has a cylindrical plug body, a ventilation means, and a liquid transport pipe. The plug main body is tightly sealed to the opening portion. The ventilation means has an opening penetrating from the outside of the plug main body toward the opening, and is capable of venting the pressurized fluid to the inside of the inner vessel. The liquid transport pipe has one end reaching the bottom surface of the inner container and the other end protruding from the plug main body, and is sealably mounted to the plug main body. Then, the compressed fluid is pressurized to the air layer of the inner container through the ventilation means, whereby the liquid medicine is discharged from the other end of the liquid transportation pipe.

The fact that the inner container is formed in the shape of a cylinder includes a shape in which the inner container includes a shape formed in the column of the employee and the inner container has a shape in which the upper surface area is formed in a trapezoid shape larger than the bottom surface area. The fact that the inner container is formed in the shape of a cylinder does not exclude that the opening protrudes on the upper surface of the inner container. The pail can for a liquid medicine does not necessarily exclude that the inner container is formed in a square shape. However, in order to resist the deformation such as the ease of manufacture of the inner container or the expansion due to the internal pressure, the inner container is preferably cylindrical rather than square.

The inner container made of synthetic resin inner resin may be an inner container made of a synthetic resin or an inner container made of plastic and can be mass-produced. In addition, the inner container made of synthetic resin has an inner container which is made of a synthetic resin in which chemicals contained in the inner container, that is, a chemical substance, come into contact with the inner container and are difficult to be contaminated by a chemical reaction, for example, ions .
