• the screw rotating cylinder 260 and the end cap 270 configured as described above have an inner diameter that is one size larger than the outer diameter of the screw 42. As a result, as shown in FIG. 23, the screw 42 can enter into the screw rotating cylinder 260 and the end cap 270.
• the inner diameter of the region 261a of the screw rotating cylinder 260 is also one size larger than the outer diameter of the region 271a of the end cap 270. As a result, the region 271a of the end cap 270 can enter into the region 261a of the screw rotating cylinder 260 to connect the screw rotating cylinder 260 and the end cap 270.
• region 271a of the end cap 270 enters into the region 261a of the screw rotating cylinder 260 to connect the screw rotating cylinder 260 and the end cap 270, so that the region 261a of the screw rotating cylinder 260 and the region 271a of the end cap 270 have the same axial length.

• the region 271a of the end cap 270 into the screw rotation tube 260 is configured to be slightly flexible in the radial direction by forming six anti-rotation slits 272. Therefore, when the region 271a of the end cap 270 fits into the region 261a of the screw rotation tube 260, the mating claws 273 come into contact with the mating claws 265 and overcome the mating claws 265 while curving inward, and as shown in FIG.
• the mating claws 265 and mating claws 273 engage with each other, and the screw rotation tube 260 and the end cap 270 are connected. This prevents the end cap 270 from easily coming off the screw rotation tube 260 when the screw rotation tube 260 and the end cap 270 are connected.
• the fitting claws 273 are provided around the entire circumference of the outer circumferential surface of the end cap 270, excluding the anti-rotation slits 272. This means that when inserting the region 271a of the end cap 270 into the region 261a of the screw rotation tube 260, it is not necessary to align the fitting claws 265 and 273.
• anti-rotation rib 264 of screw rotation tube 260 is inserted into anti-rotation slit 272 of end cap 270 to engage with it.
• two anti-rotation ribs 264 are provided in opposing regions on the inner peripheral surface of screw rotation tube 260, while six anti-rotation slits 272 are provided at equal intervals of 60° around the circumference of end cap 270.
• the number of anti-rotation slits 272 may be the same as that of anti-rotation ribs 264, but if multiple anti-rotation ribs 264 are provided at equal intervals around the circumference of screw rotation tube 260, while multiple anti-rotation ribs 264 are provided at equal intervals around the circumference of end cap 270 in a multiple of anti-rotation ribs 264, it will be easier to align screw rotation tube 260 and end cap 270 when connecting screw rotation tube 260 and end cap 270. It is sufficient that one anti-rotation rib 264 is provided on the inner circumferential surface of the screw-rotating tube 260.
• one anti-rotation slit 272 is also provided on the end cap 270, but if multiple anti-rotation slits 272 are provided around the circumference of the end cap 270, it becomes easier to align the screw-rotating tube 260 and the end cap 270.
• the mating claws 265 and 273 engage with each other, and the anti-rotation rib 264 enters and engages with the anti-rotation slit 272, connecting the screw rotation tube 260 and the end cap 270.
• the cosmetic holder 202 configured as described above is attached to the container base 20, 120 and used in the same manner as the container body 10, 110 in the above-described embodiment.
• the end cap 270 constituting the fitting tube 241 of the cosmetic holder 202 fits into the tube fitting portion 26a of the dial 26 of the container base 20, 120, and the unevenness caused by the knurling 275 formed on the outer circumferential surface of the end cap 270 fits into the unevenness of the tube fitting portion 26a.

• the anti-rotation rib 264 extends in the axial direction of the screw rotation tube 260, and the anti-rotation slit 272 engages with the lower end side of the screw rotation tube 260. Therefore, when the end cap 270 rotates in the circumferential direction, the screw rotation tube 260 also rotates in the circumferential direction accordingly. In this way, the knurling 275 assists the rotation of the fitting tube 241.
• a protrusion 263 is provided on the inner peripheral surface of the screw rotation cylinder 260, and this protrusion 263 engages with the screw groove 251 of the screw 42. Therefore, when the screw rotation cylinder 260 rotates in the circumferential direction, the screw 42 moves up and down inside the fitting cylinder 241, and the inner plate 43 moves up and down accordingly.
• the protrusion 263 on the screw rotating cylinder 260 engages with the screw groove 251 of the screw 42, while the outer circumferential surface of the end cap 270 is knurled 275 to rotate the end cap 270 with the rotation of the dial 26.
• the rotation prevention rib 264 of the screw rotating cylinder 260 engages with the rotation prevention slit 272 of the end cap 270, so that when the end cap 270 rotates using the knurling 275, the screw rotating cylinder 260 also rotates, and the inner plate 43 moves up and down.
• the configuration for rotating the screw rotating cylinder 260 with the rotation of the end cap 270 is realized by the rotation prevention rib 264 of the screw rotating cylinder 260 and the rotation prevention slit 272 of the end cap 270. Therefore, by simply inserting a part of the end cap 270 into the screw rotating cylinder 260, the screw rotating cylinder 260 can easily rotate with the rotation of the end cap 270.
