DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Further description of the present invention in detail will be made below in combination with drawings and embodiments.

[0017] Referring to FIG. 1 to FIG. 7, the embodiment of the present invention provides a gum-free environmental-friendly lipstick tube, including a lifting tube 1, a spiral tube 2, a median bundle core 3 and a base 4 mounted successively in a sleeving manner from inside to outside.

[0018] Referring to FIG. 2 to FIG. 5, an inner wall of the base 4 is provided with a first flange 401 and a plurality of strip-type grooves 402, the spiral tube 2 is provided with a first annular groove 201 corresponding to the first flange 401 and a strip-type clamping block 202 corresponding to the strip-type groove 402, the spiral tube 2 and the base 4 are fixed via the first annular groove 201 and the strip-type clamping block 202, and it is unnecessary to fix via a gum body, thereby playing an environmental protection role; the spiral tube 2 is further provided with a second flange 203, an inner wall of the median bundle core 3 is provided with a second annular groove 301 corresponding to the second flange 203, the spiral tube 2 can rotate relative to the median bundle core 3, an inner wall of the spiral tube 2 is provided with an internal thread 204, and the lifting tube 1 is provided with an external thread 101 corresponding to the internal thread 204; therefore, when the spiral tube 2 rotates, it is to drive the lifting tube 1 to ascend by means of the matched internal and external threads; and during use, the base 4 is rotated, and the base 4 drives the spiral tube 2 to rotate, so that the lifting tube 1 ascends.

[0019] Referring to FIG. 6 to FIG. 7, the base 4 is provided with an upper cover 5 in a sleeving manner, herein the top end of the base 4 is provided with a spherical protrusion 403, an inner wall of the upper cover 5 is provided with a third annular groove 501, and the spherical protrusion 403 can be clamped into the third annular groove 501 to play a positioning role.

[0020] Referring to FIG. 4 to FIG. 5, the lifting tube 1 is provided with a first special-shaped surface 102, and an inner wall of the median bundle core 3 is provided with a second special-shaped surface 302 corresponding to the first special-shaped surface 102. The lifting tube 1 is prevented from rotating horizontally in a lifting process along the median bundle core 3 by matching the two special-shaped surfaces.

[0021] Referring to FIG. 2, the spiral tube 2 is further provided an elastic sheet 205. The elastic sheet 205 can compensate changes of twisting forces due to the median bundle cores of different dimensions, so that the lipstick tube is more stable and smooth in hand feeling when being used.

[0022] According to the gum-free environmental-friendly lipstick tube in the embodiment of the present invention, a thread of a conventional median bundle tube is adjusted to the internal spiral tube and lifting tube, so that in a machining process of the median bundle tube, and the median bundle tube can be machined by using the PET material, and the lipstick tube is higher in strength and convenient to recover, thereby playing an environmental-friendly role; and the spiral tube is matched with the base, and it is unnecessary to gum and reinforce, so that environmental protection is further facilitated; the elastic sheet on the spiral tube can compensate changes of twisting forces caused by the median bundle tubes with different dimensions, so that the lipstick tube is more stable and smooth in hand feeling when being used.

[0023] The above examples are the preferred embodiments of the present invention. It should be noted that improvements and embellishments shall be made within the protection range of the disclosure to those skilled in the technical field without departing the principle of the present invention.
