Abstract: A packaging tube is disclosed, which includes a cartridge core and a base; the cartridge core and the base are both made of metal materials, the cartridge core has an axial direction in space, the cartridge core comprises a bead, a fork and a spiral in sequence from inside to outside; the inner wall of the spiral is provided with a thread structure, when the spiral rotates relative to the fork, the thread structure drives the bead to slide in the axial direction relative to the fork, an adaptation structure capable of being inserted and pulled in the axial direction is provided between the fork and the base, and the adaptation structure limits the relative movement of the fork and the base in the axial direction and in a circumferential direction.

Abstract: A lipstick tube cartridge core comprising a ball (1), a fork (2), a spiral (3), and a cartridge (4). The spiral (3) and the cartridge (4) are provided therebetween with a keyway structure (33 and 43) arranged in the axial direction and an engaging ring (31 and 42) and engaging groove (32 and 41) structure arranged in the circumferential direction. As the spiral (3) and the cartridge (4) are provided therebetween with the keyway structure (33) arranged in the axial direction and the engaging ring (31 and 42) and engaging groove (32 and 41) structure arranged in the circumferential direction, retention of the spiral (3) and of the cartridge (4) is implemented without using a glue, thus preventing a scenario in which a cosmetic paste is contaminated by the glue.
