For example, there is a container for dispensing cosmetics as shown in Fig. 3 (Utility Application No. 158887/1987 (No. 6898 No. 5-689) filed by the present applicant).
etc.).

This consists of a non-replaceable member A and a replaceable member B housed in the non-replaceable member A, and the non-replaceable member A has at least a decorative tube 1 with an open top end and an upper outer surface of the decorative tube 1. The replacement member B is formed with a cap 3 that fits into the lower part of the peripheral wall 2, and the replacement member B fits the lower half of the first cylinder wall 4 into the decorative cylinder 1, and the upper part of the first cylinder wall 4. A bar-shaped cosmetic 7 is placed in a guide tube 5 whose half part projects upward from the cosmetic tube 1, and an upper part of a second tube wall 6 which is fitted into the lower half of the first tube wall 4 so as to be vertically movable. An engaging cylindrical portion 10 having an open lower end surface is provided vertically from the lower end of the lifting tube 8 into which the lower portion is fitted, and the shaft portion 9 screwed onto the inner surface of the lower half of the second cylindrical wall 6. A mating tube portion 10 is formed with a central shaft 11 which is rotatably connected to the lower end of the guide tube 5 and unrotatably connected to the lower end of the decorative tube 1.

To explain in more detail, the decorative tube 1 includes a decorated metal tube 12 with a bottom, and a decorated metal tube 12 with a bottom.
A bottomed synthetic resin auxiliary cylinder 13 fitted inside;
The metal tube 12 is divided into a metal middle member 14 connected to the upper end thereof. The above auxiliary tube 13
has an engaging protrusion 15 circumferentially provided on its lower inner surface, and a spline groove 17 formed on the outer surface of a shaft portion 16 that stands up from the center of the bottom wall.

The cap 3 has a bar-shaped cosmetic 7 inside its upper part.
A cylindrical sealing member 18 made of synthetic resin is fitted to prevent drying.

The upper guide tube 5 has a first tube wall 4 divided into a lower tube wall 19 made of synthetic resin and an upper tube wall 20 made of metal connected to the upper end of the lower tube wall 19. The inner surface of the lower cylinder wall 19 is spline engaged 21 with the outer surface of the second cylinder wall 6 of the elevating cylinder 8, which is also made of synthetic resin.

Therefore, when the decorative tube 1 is rotated in a predetermined direction with respect to the guide tube 5 after the cap 3 is removed, the inner shaft 11, which rotates together with the decorative tube 1, is rotated to be screwed into the inner shaft 11 and the above-mentioned The lifting tube 8 whose rotation is prevented by the guide tube 5 is screwed up and the bar-shaped cosmetic 7 is lifted up.
is rolled out.

On the other hand, when the bar-shaped cosmetic product 7 is worn out and the replacement member B is to be replaced, by pulling the guide tube 5 upward with respect to the cosmetic tube 1, the center shaft 11 that engages with the guide tube 5 in the vertical direction is also pulled up. , thereby causing the engaging protrusion 1
5 is disengaged from the engagement groove 24, and the replacement member B consisting of the guide tube 5 and the like is pulled out from the non-replaceable member A consisting of the decorative tube 1 and the like.

"Problems to be Solved by the Invention" In the above-mentioned conventional cartridge-type cosmetic bar dispensing container, the engagement groove 24 on the replaceable member B side is forced upward into the engagement protrusion 15 on the non-replaceable member A side. Since they are engaged so that they can be crossed over, the sealing performance (degree of press-fitting) of the sealing member 18 in the cap 3 to the upper cylinder wall 20 in the guide cylinder 5 is enhanced to further strengthen prevention of drying of the bar-shaped cosmetic product 7. , each time the cap is removed for makeup, the replacement member B is pulled by the cap 3 and the non-replaceable member A is pulled.
(Cosmetic tube 1) There was a problem that it could be pulled out from inside.

Therefore, the present invention improves the sealing performance of the cap to the guide tube by effectively screwing the guide tube into a decorative tube consisting of two upper and lower members that are rotatably connected to each other. An object of the present invention is to provide a cartridge type rod-shaped cosmetic dispensing container.

"Means for Solving the Problems" In order to achieve the above object, the cartridge-type bar-shaped cosmetic dispensing container according to the present invention has a non-replaceable member A.
and a replaceable member B housed in the non-replaceable member, and the non-replaceable member A includes at least a decorative tube 1 having an open upper end surface, and a cap in which a lower part of the peripheral wall 2 is fitted onto the upper outer surface of the decorative tube. 3, and the replacement member B includes a guide tube 5 in which the lower half of the first tube wall 4 is fitted into the cosmetic tube so that the upper half protrudes upward from the cosmetic tube; A lifting cylinder 8 in which a lower part of a bar-shaped cosmetic 7 is fitted into the upper part of a second cylinder wall 6 that is vertically movably fitted into the lower half of the first cylinder wall, and a lower half of the second cylinder wall. An engaging cylinder part 10 is vertically disposed from the lower end of the shaft part 9 screwed into the inner surface of the part, and the engaging cylinder part is rotatably rotated to the lower end of the guide cylinder and to the lower end of the cosmetic cylinder. Central axis 11 linked to immobility
