The cylindrical body 9 extends along the central axis O and has a cylindrical shape as a whole. The tubular body 9 of the present embodiment has a circular outer peripheral surface and a cross-shaped inner peripheral surface in a plan view, and the shaft 5e can be inserted inside the tubular body 9 . That is, the tubular body 9 is detachable from the shaft 5e and is held in a non-rotating manner. The outer peripheral surface of the cylindrical body 9 is provided with a second threaded portion 9a having a male thread shape. The second threaded portion 9a is screwed onto the first threaded portion 7c.

A circular shaft hole 9b is provided at the upper end of the cylindrical body 9. As shown in FIG. The inner diameter of the shaft hole 9b is slightly larger than the outer diameter of the upper end portion of the support shaft 8d, and is smaller than the outer diameter of the lower end portion of the support shaft 8d, so that the cylindrical body 9 rotates with respect to the support shaft 8d. It is possible and retained. A vertically extending slit may be provided in the cylindrical body 9 so that the cylindrical body 9 can be elastically deformed when the support shaft 8d is inserted into the shaft hole 9b. 2(a), the guide wall 7d extends longer downward than the tubular body 9 when the tubular body 9 is held by the support shaft 8d.

It has a cap outer peripheral wall 10b surrounding the . The cap outer peripheral wall 10b is configured to be detachably fitted to the lower outer peripheral wall 3a, and the cap 10 is held by the base body 3. As shown in FIG.

When using the dispensing container 1 composed of such members, the cap 10 is removed from the base body 3, and the rotating body 5 is moved so that the second threaded portion 9a rises with respect to the first threaded portion 7c. rotate. As shown in FIG. 1, the lower wall 5b of the rotor 5 is in contact with the projection 4c. That is, since the rotating body 5 is supported by the bottom lid body 4 with a small contact area by the protrusions 4c, the rotating body 5 can be rotated smoothly. Since the inner tray 8 rises with respect to the cartridge main body 7 together with the cylindrical body 9 according to the amount of rotation of the rotor 5 , the rod-shaped content (not shown) held in the inner tray 8 is drawn out from the cartridge main body 7 . Thereafter, while holding the base body 3 with fingers, the stick-shaped content can be applied to the application destination. A retainer 9c is provided at the lower end of the tubular body 9, so that the elevated tubular body 9 will not slip out of the cartridge main body 7 even if the rotating body 5 is rotated excessively. After the application is completed, the cylindrical body 9 and the inner plate 8 are drawn into the cartridge main body 7 by rotating the rotating body 5 in the reverse direction, so that the rod-shaped contents can be accommodated inside the cartridge main body 7. .

When replacing the used cartridge 6 with a new cartridge 6 (see FIG. 4) after using up the rod-shaped content, the claws 7e of the used cartridge 6 attached to the base 2 are pushed radially as shown in FIG. Press inward. As a result, the claw portion 7e is bent radially inward, so that the engagement between the claw portion 7e and the hole portion 3d is released. Further, the tubular body 9 can be vertically removed from the shaft body 5e. Therefore, the cartridge 6 can be removed from the base 2 by pulling up the used cartridge 6 with respect to the base 2 .

The claw portion 7e of the present embodiment is provided in the longitudinal direction of the plate-like wall 7b, and a sufficient space is secured radially inside the claw portion 7e. That is, if there is no room for space on the radially inner side of the claw portion 7e, for example, the claw portion 7e must be made small. Although it becomes difficult to hold it, by providing the claw portion 7e in the longitudinal direction of the plate-like wall 7b as in the present embodiment, such a problem does not occur.

The new cartridge 6 shown in FIG. 4 has a sheet material 7g attached to the upper end portion of the upper outer peripheral wall 7a in order to keep the rod-shaped contents in a sealed state. The sheet material 7g may be, for example, an aluminum sheet or a synthetic resin sheet. Then, a new cartridge 6 is inserted into the original base body 3 with the sheet material 7g still attached (which may be removed first). Here, the guide wall 7d of the cartridge main body 7 extends longer downward than the cylindrical body 9. As shown in FIG. As shown in FIG. 2(a), the guide wall 7d is shaped along the inner peripheral surface of the lower outer peripheral wall 3a in the lateral direction. That is, when the cartridge 6 is attached to the base body 3, the guide wall 7d can guide the cartridge 6 to a predetermined position, so there is no need to pay special attention to the positioning of the cylindrical body 9 and the shaft body 5e. . Therefore, the cartridge 6 can be easily attached to the base body 3 . Note that the guide walls 7d extend longer downward than the tubular body 9 and are provided on both sides of the tubular body 9. It also has the effect of protecting

As described above, the lower surface of the claw portion 7e is provided with the inclined surface 7f that is inclined downward and inward in the radial direction. That is, when the cartridge 6 is inserted into the base body 3, the inclined surface 7f comes into contact with the upper end surface of the lower outer peripheral wall 3a and the claw portion 7e is bent radially inward. The cartridge 6 can be attached to the base body 3 without doing so.

After that, it can be used as the dispensing container 1 by peeling off the attached sheet material 7g. As described above, according to the dispensing container 1 of the present embodiment, the base 2 and the cap 10 can be reused after the rod-shaped content is used. It is superior in terms of resource saving and environmental load reduction.
