The present invention relates to a feeding container.

Conventionally, for example, as shown in Patent Document 1 below, a holding cylinder for holding a rod-shaped content, a regulating cylinder which is externally mounted on the holding cylinder and has vertical holes penetrating in the radial direction, and a holding cylinder on the regulating cylinder. It is provided with an outer cylinder that is externally rotatable in the circumferential direction along the central axis of the above and has a spiral groove formed on the inner peripheral surface, and a locking cylinder member that regulates the ascending movement of the restricting cylinder with respect to the outer cylinder. A feeding container in which a guided protrusion inserted into a spiral groove through a vertical hole is formed in a holding cylinder is known.
In this feeding container, the outer cylinder and the regulation cylinder are rotated relative to each other in the circumferential direction, so that the guided protrusions are restricted from moving in the circumferential direction with respect to the regulation cylinder by the inner peripheral surface of the vertical hole. By moving relative to each other, the holding cylinder moves in the axial direction along the central axis with respect to the outer cylinder and the regulation cylinder.

Further, the locking cylinder member is provided with a synthetic resin main body cylinder whose lower portion is fitted in the upper end portion of the outer cylinder and whose upper portion protrudes upward from the upper end opening of the outer cylinder, and has a diameter on the outer peripheral surface of the main body cylinder. A flange portion that protrudes outward in the direction and is placed on the upper end opening edge of the outer cylinder is formed, and a metal cylinder that is detachably fitted in a climax cylinder-shaped cap is outside the upper part of the main body cylinder. It is known that the metal cylinder is fitted and has a metal flange portion that covers the upper surface of the flange portion of the main body cylinder.

However, in the conventional feeding container, it is difficult to finish the connection portion between the outer peripheral surface of the cylinder portion and the upper surface of the metal flange portion of the metal cylinder to a mirror surface by surface treatment such as polishing, for example. There is a problem that it is not possible to easily manufacture a feeding container having a metal cylinder finished in.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a feeding container that can be easily manufactured even if it has a mirror-finished metal cylinder.

In order to solve the above problems, the present invention proposes the following means.
The feeding container according to the present invention has a holding cylinder for holding a rod-shaped content, a regulating cylinder which is outerly mounted on the holding cylinder and has vertical holes formed in the radial direction, and a central axis of the holding cylinder on the regulating cylinder. It is provided with an outer cylinder that is externally rotatable in the circumferential direction along the circumference and has a spiral groove formed on the inner peripheral surface, and a locking cylinder member that restricts the ascending movement of the restricting cylinder with respect to the outer cylinder. A guided protrusion inserted into the spiral groove through the vertical hole is formed in the holding cylinder, and the lower portion of the locking cylinder member is fitted into the upper end portion of the outer cylinder, and the upper portion is the upper end of the outer cylinder. A main body cylinder that protrudes upward from the opening is provided, and a flange portion that protrudes outward in the radial direction and is placed on the upper end opening edge of the outer cylinder is provided on the outer peripheral surface of the main body cylinder. On the upper part, a metal cylinder detachably fitted in a climax cylinder-shaped cap is externally fitted with the upper surface of the flange portion exposed.

According to the present invention, the metal cylinder is fitted on the upper part of the main body cylinder with the upper surface of the flange portion exposed, and does not have the metal flange portion covering the upper surface of the flange portion. The outer peripheral surface of the can be easily mirror-finished by surface treatment.
Since the metal cylinder is detachably fitted in the climaxed tubular cap, the user who attaches and detaches the cap can operate a high-class product as compared with the configuration in which the resin cylinder is detachably fitted in the cap. It can give a feeling when doing.

An annular groove into which the lower end of the metal cylinder is inserted may be formed on the upper surface of the flange.

In this case, since an annular groove in which the lower end of the metal cylinder is inserted is formed on the upper surface of the flange portion, the corner portion formed by the lower end opening edge and the outer peripheral surface of the metal cylinder is located in the annular groove and is external. It can be prevented from being exposed to.

The flange portion may be formed of a synthetic resin material, and a metal-based film body may be provided on the upper surface of the flange portion.

In this case, since a film body mainly composed of metal is provided on the upper surface of the flange portion, even if the metal flange portion is not provided on the metal cylinder, the upper end portion of the outer cylinder is axially adjacent and the cap is attached. The appearance of the part that can be visually recognized from the outside in the removed state can be maintained in the same manner as the current one.

According to the present invention, even if the metal cylinder has a mirror-finished surface, it can be easily manufactured.
