[0002]

2. Description of the Related Art Conventionally, there has been a hollow application container for containing a liquid medicine applied to the skin to cure stiff shoulders and skin diseases. In such a coating container, a tapered nozzle-shaped inner plug is provided at an outlet of the container body, and a spout which is a small through-hole is provided at the tip of the inner plug. Such a coating container has a small take-out port so that the contents do not easily flow out when not in use.

However, since the application container has a small take-out opening, it is necessary to perform operations such as shaking the container or pressing the body of the container when pouring out the contents. It was difficult to finely adjust the appropriate amount and apply.

[0004] Therefore, there is a coating container as shown in FIG. 5 as a device for easily taking out the contents and preventing the contents from flowing out when not in use. This coating container is attached to a cylindrical take-out port 2 of a container body 1 made of a somewhat hard synthetic resin by fitting an inner plug 3 made of a somewhat hard synthetic resin. The inner plug 3 is formed with a nozzle portion 4 that protrudes in a conical shape in the direction in which the outlet 2 protrudes, and a cylindrical pouring portion 5 is integrally formed at the tip of the nozzle portion 4. On the lower end side of the inner plug 3, that is, on the peripheral edge of one end of the container body 1,
An inwardly protruding step 6 is formed around the circumference.
