Field of the Invention The present invention relates to a container for storing a stick-like article such as a stick-like lipstick so as to be able to be fed out. 2. Description of the Related Art Heretofore, a well-known dispensing container comprising a body having a lipstick attached thereto and a cap which covers the body is well known. An example of the body includes an inner cylinder in which a lipstick is vertically movably accommodated, an outer cylinder having a spiral groove on the inner peripheral surface, and an operation cylinder located outside the outer cylinder. The inner cylinder and the operating cylinder rotate clockwise or counterclockwise around the outer cylinder by integrating their bottoms located below the outer cylinder via a connecting member. With the rotation, the lipstick rises or falls inside the inner cylinder. In the conventional feeding container, when the inner cylinder and the operation cylinder are connected to each other at their bottoms, both bottoms are thickened so that the connection is easy. It has to be made, and it is inevitable that the height of the feeding container is increased. Also, instead of connecting the bottoms to each other, the inner cylinder and the operation cylinder can be connected to each other by the peripheral surfaces. In this case, however, the cross section of the operation cylinder in the radial direction may be circular or may be multiple. If you make it square,
The inner cylinder must have a shape corresponding to the operation cylinder. Since the connecting part between the inner cylinder and the operation cylinder requires high dimensional accuracy, it is necessary to prepare the inner cylinder and the operation cylinder having such parts each time the appearance of the operation cylinder is changed This causes an increase in costs in various points such as expenses. [0004] It is an object of the present invention to improve the conventional feeding container such that the inner cylinder and the operating cylinder can be connected without increasing the height of the container. [0005] In order to solve the above problems,

The body comprises a body having a vertical direction and a radial direction perpendicular to the vertical direction, the rod-shaped article being able to be fed out from an opening formed upward, and a removable cap which covers the body from above. The body has a movable member, an inner cylinder, an outer cylinder, and an operation cylinder arranged in order from inside to outside so as to share the axis extending in the vertical direction, and the movable member has a rod-like shape. An article is attachable and movable in the vertical direction, and the inner cylinder is formed with an opening in the upward direction and is located outside the movable member to move the movable member in the vertical direction. The outer cylinder is provided so as to be movable and rotatable about the axis together with the inner cylinder, and the outer cylinder has an opening formed in the upward direction, is located outside the inner cylinder, and moves the inner cylinder in the direction around the axis. The operation cylinder is rotatably housed, and is connected to the inner cylinder so that the operation cylinder is located outside the outer cylinder and can rotate together with the inner cylinder in a direction around the axis. Between the outer cylinder and the operation cylinder, an intermediate cylinder that is fixed to the peripheral surface of the operation cylinder and that is rotatable around the outer cylinder while surrounding the outer cylinder is interposed, And the inner peripheral surface of the cap are in close contact with each other in an airtight state. The features of the present invention in such a feeding container are as follows. Below the intermediate cylinder, a second intermediate cylinder separate from the intermediate cylinder is interposed between the outer peripheral surface of the inner cylinder and the inner peripheral surface of the operation cylinder. The second intermediate cylinder is fixed to an outer peripheral surface of the inner cylinder and an inner peripheral surface of the operation cylinder in a direction around these peripheral surfaces so that the second intermediate cylinder can rotate together with the inner cylinder and the operation cylinder. A tube is connected to the inner tube. The inner cylinder is the second cylinder.
