PROBLEM TO BE SOLVED: To provide a cosmetics delivery container in which assemblability is improved between a male screw threaded core-chuck member and a female screw cylinder. SOLUTION: The cosmetics delivery container 1 includes: a distal cylinder 10 in which a tip opening hole 11 is formed at the tip end; a proximal cylinder 20 which is freely rotatably assembled into the distal cylinder 10; a core chuck member 30 which has a male screw 35 on the outer periphery and which can be moved forward and backward by relative rotation of the distal cylinder 10 and the proximal cylinder 20; and a female screw cylinder 40 which has the female screw 42 formed to be screwed on the male screw 35 and which synchronously rotates by engaging with the inner periphery of the proximal cylinder 20. In the cosmetics delivery container 1, a bar like cosmetic material A held at the tip end of the core chuck member 30 is made to move forward and backward from the tip opening hole 11 by the relative rotation of the distal cylinder 10 and the proximal cylinder 20. The female screw cylinder 40 is formed in a C-shaped cross section having a slit 44 with which a part of the periphery opens, wherein the female screw 42 is formed in a part of the inner peripheral wall 48 oppositely facing the slit 44.
