2. Description of the Related Art Heretofore, a container for accommodating a stick-shaped cosmetic such as lipstick has been provided with a spiral feed-out mechanism, and the stick-shaped cosmetic has been advanced and retracted by performing a rotary feeding operation. The spiral feeding mechanism includes a holding cylinder in which a rod-shaped cosmetic material is fitted and held, and a threaded piece is protruded from a side wall, and a guide in which the holding cylinder is slidably mounted vertically and the threaded piece of the holding cylinder penetrates the side wall. The guide cylinder includes a guide cylinder having a groove formed in the axial direction, and a spiral cylinder which is rotatably held on the outer periphery of the guide cylinder, and has a spiral groove on an inner wall into which a threaded piece of the holding cylinder is screwed. I was In this feed-out mechanism, at least one of the upper and lower ends of the guide groove and the spiral groove needs to be closed for the upper limit of the rising and the lower limit of the lowering of the holding cylinder.

However, since the threaded piece projecting from the holding cylinder needs to penetrate through the guide groove and be screwed into the spiral groove, when the holding cylinder is mounted in the guide cylinder, it is necessary to mount the holding cylinder inside the guide cylinder.
No. 18, Japanese Utility Model Application Laid-Open No. 4-112310, etc., the upper end of the guide cylinder is made openable by cutting off the upper end of the guide cylinder, or the lower end of the guide cylinder is used, as in Japanese Utility Model Publication No. 56-88411. The lower end of the guide groove is closed after the holding groove is attached to the holding groove, or a slit is provided on the side wall of the holding tube to form an elastic part as shown in Japanese Utility Model Laid-Open Publication No. 3-49711. The screwing piece is provided so as to protrude inward, and the screwing piece is bent inward.
A number of means have been proposed, such as a configuration in which the holding cylinder and the screwing piece are separated parts, and the holding cylinder is mounted on the guide cylinder, and then the screwing piece is mounted on the holding cylinder through the guide groove. I have.

[0004]

Among these, a notch is provided at the upper end of the guide cylinder so that the upper end of the guide cylinder can be expanded. The upper end of the guide cylinder is deformed to force the threaded piece of the holding cylinder to guide. There is a risk that an excessive force is applied to the threaded piece and the upper end of the guide cylinder because of the protrusion into the groove, and the threaded piece or the guide cylinder may be damaged. Also, when an impact is applied from the side of the container, such as when the stick-shaped cosmetic container is dropped, the tip of the stick-shaped cosmetic whose lower end is held in the holding tube swings and touches the inner wall of the guide tube. Was. in this case,
If there is a notch at the tip of the guide cylinder, the mark will remain on the stick-shaped cosmetic, losing its commercial value. Also,
When mounting the holding cylinder on the guide cylinder, it is necessary to push the holding cylinder into the guide groove by prying the holding cylinder while expanding the upper end of the guide cylinder, so it is absolutely necessary to perform this manually Had become a bottleneck for automation.

[0005] Further, in the configuration in which the lower end of the guide groove is opened to the lower end of the guide cylinder, a mechanism for closing the lower end of the guide groove is separately required. Similarly, the configuration in which the threaded piece of the holding tube is bent inward requires a mechanism for preventing the screwed piece from bending inward after the holding tube is mounted. The configuration in which the holding cylinder and the screwing piece are separate parts requires a mechanism for positioning the holding cylinder in the guide cylinder when the screwing piece is mounted on the holding cylinder. In each case, productivity was hindered, and the number of parts increased, resulting in increased costs.

The configuration will be described. The holding cylinder 1 holding the lower end of the stick-shaped cosmetic 4 such as lipstick has a rotation preventing piece 5 protruding from a side wall. The rotation preventing piece 5 protrudes in a range equal to or less than half of the outer circumference of the holding cylinder 1.

The holding cylinder 1 is mounted inside a guide cylinder 6 so as to be slidable up and down. A guide groove 7 having a width corresponding to the width of the rotation preventing piece 5 of the holding cylinder 1 is formed in the side wall of the guide cylinder 6 so as to be long in the axial direction. As a result, the rotation preventing piece 5 of the holding cylinder 1 is engaged with the guide groove 7 of the guide cylinder 6,
The holding cylinder 1 is guided in the guide cylinder 6 so as to be non-rotatably slidable up and down. The upper end and the lower end of the guide groove 7 are closed, and the rotation preventing piece 5 is brought into contact with the guide groove 7 to form the top dead center and the bottom dead center of the holding cylinder 1. At the upper end and lower end of the guide groove 7, a horizontal portion 8 corresponding to the height of the rotation preventing piece 5 of the holding cylinder 1 is provided.
Is locked at the top dead center and bottom dead center. The tip of the rotation preventing piece 5 projects outside the side wall of the guide cylinder 6.

When the holding cylinder 1 is mounted on the guide cylinder 6, if the holding cylinder 1 is brought into contact with the guide groove 7 and pressed from the lateral direction, the edge of the guide groove 7 will be curved on the outer peripheral surface of the holding cylinder 1. Because of the contact, the guide groove 7 is pushed and expanded by the holding cylinder 1, and the holding cylinder 1 can protrude into the guide cylinder 6. After the holding tube 1 is mounted, the guide tube 6 is restored by its own elasticity so that the holding tube 1 does not fall off.

As described above, according to the present invention, since the guide groove 7 of the guide cylinder 6 is formed to be slightly wider than the diameter of the holding cylinder 1, the holding cylinder 1 can be inserted from the lateral direction. I can do it. In addition, since the curved surface of the holding cylinder 1 is inserted in a state of contact with the edge of the guide groove 7 at the time of insertion, the edge of the guide cylinder 6 is widened so that the holding cylinder 1 enters the inside. It has become. Moreover, the guide cylinder 6
By holding the cylindrical body in which the spiral groove 3 is screwed around the outer periphery of the rod so as to be rotatable, the holding cylinder 1 is prevented from dropping and the guide cylinder 6 is completely prevented from being deformed. Functionally it has not changed at all.

Moreover, since the upper end of the guide groove 7 is closed, the upper end of the guide cylinder 6 is completely pipe-shaped.
Even if a shock is applied to the container from the lateral direction and the tip of the rod-shaped cosmetic 4 comes into contact with the inner wall of the guide tube 6, traces of contact with the side surfaces of the rod-shaped cosmetic 4 hardly remain, and the possibility of losing commercial value is high. Is running low. In addition, the holding cylinder 1 is deformed and mounted by pressing the holding cylinder 1 against the guide cylinder 6 from the lateral direction, and a special operation such as twisting is not required, so that the mounting process can be automated. In addition, in the configuration using the knurled spiral groove 14 described in the second embodiment, since there is no need to align the screwing pieces 2 and the spiral groove 3, the process of mounting the sleeve 10 can be simplified.

As described above, the present invention has the same functions as the conventional stick-shaped cosmetic dispensing container, while simplifying assembly and adapting to automation. Cost can be reduced.
