[0054] The limiting component 5 comprises a first limiting member 51 disposed in the inner cavity of the lipstick tube body 3 and a second limiting member 52 disposed at the head of the bead 4. The first limiting member 51 cooperates with the second limiting member 52 to control the linear motion of the bead 4.

[0055] In a specific implementation, the outer cover 12 and the bottom cover 11 can be designed to be snap-fitted. When the bottom cover and the outer cover are made of PP material, a circle of annular bosses are arranged outside the top of the bottom cover to fit and snap into the groove at the bottom of the inner wall of the outer cover; when the bottom cover and the outer cover are made of PET material, in order to achieve smooth removal of the cover, at least three circular bosses are arranged along the circumference of the top of the bottom cover to fit and snap into the groove at the bottom of the inner wall of the outer cover.

[0056] In a specific implementation, the bottom screw 2 is arranged in the inner cavity of the bottom cover 11, the bottom end of the bottom screw 2 is fixedly connected to the bottom cover 11, and an interval for accommodating the bottom of the lipstick tube body 3 is reserved between the upper half of the bottom screw 2 and the bottom cover 11. The tail of the lipstick tube body 3 is placed in the gap between the bottom screw 2 and the bottom cover 11 and is rotatably connected to the bottom screw 2. The tail end of the bead 4 is rotated in the inner cavity of the bottom screw 2, and the top of the bead 4 is placed in the inner cavity of the lipstick tube body 3.

[0057] Preferably, the connection design between the bottom screw 2 and the bottom cover 11 is as follows: a plurality of vertical third limiting grooves 111 are provided at the bottom of the inner wall of the bottom cover 11, and a circle of fourth limiting grooves 112 are provided above the third limiting grooves 111 on the inner wall of the bottom cover 11; a vertical first limiting boss 22 is provided at the tail of the bottom screw 2 at a position corresponding to the third limiting groove 111, and a fourth annular boss 23 is provided on the bottom screw 2 at a position corresponding to the fourth limiting groove 112;

[0058] The first limiting boss 22 of the bottom screw 2 is engaged in the third limiting groove 111 to limit the rotation of the bottom screw 2 relative to the bottom cover 11; the fourth annular boss 23 of the bottom screw 2 is placed in the fourth limiting groove 112 of the bottom cover 11 to fix the bottom screw 2 to prevent the bottom screw 2 from being separated from the bottom cover 11 when in use. In this structure, when the bottom cover 11 is rotated, the bottom cover 11 will drive the bottom screw 2 to rotate.

[0059] Preferably, the connection mode of the lipstick tube body 3 and the bottom screw 2 is as follows: a fifth annular boss 24 and a third annular boss 25 are sequentially arranged above the fourth annular boss 23 of the bottom screw 2 from bottom to top, and the gap between the fifth annular boss 24 and the third annular boss 25 is a second limiting groove 26; a first limiting groove 31 is arranged at a position corresponding to the third annular boss 25 at the bottom of the inner wall of the lipstick tube body 3, and a second annular boss 32 matching the second limiting groove 26 is formed in the area between the first limiting groove 31 and the bottom surface of the lipstick tube body 3;

[0060] The third annular boss 25 of the bottom screw 2 is located in the first limiting groove 31 of the lipstick tube body 3 , and the second annular boss 32 of the lipstick tube body 3 is located in the second limiting groove 26 of the bottom screw 2 .

[0061] Preferably, the connection method between the bead 4 and the bottom screw 2 is: a first annular boss is obliquely provided on the top of the inner wall of the bottom screw 2, and the first annular boss is the first rotating part 21; the tail of the bead 4 is a threaded column, and the threaded column is the second rotating part 41. The thread rotation angle of the threaded column matches the inclination angle of the first annular boss, and the thread depth of the threaded column matches the thickness of the first annular boss. In actual use, the number and arrangement position of the first annular boss can be set as needed according to the spiral of the threaded column. During installation, the first annular boss is located in the groove between the thread teeth of the threaded column (second rotating part 41), and the first annular boss and the external thread of the threaded column are spirally matched, and the actual transmission effect is similar to the screw nut transmission fixed with a nut.

[0062] Preferably, the area in the inner cavity of the lipstick tube body 3 for accommodating the up-and-down displacement of the bead 4 is the first area 33, the first area 33 is in the form of a regular polygonal column, the inner wall of the lipstick tube body 3 connected to the first area 33 is the first stopper 51, the head shape of the bead 4 is in the form of a regular polygonal column matching the first area 33, and the outer wall of the head of the bead 4 is the second stopper 52. Because the first area 33 and the head of the bead 4 are in the form of a regular polygonal column, the inner wall of the lipstick tube body 3 and the head of the bead 4 will fit and restrict, preventing the bead 4 from rotating relative to the lipstick tube body 3, so that under the rotation of the bottom screw 2, the bead 4 will only move stably up and down along the lipstick tube body 3. In addition, the regular polygonal column pattern inside the lipstick tube body 3 of the present design is drilled and cut, so that the gap between the bead 4 and the inner wall of the lipstick tube is reduced, and it is more stable. The lipstick tube body 3 and the head of the bead 4 are actually similar to a regular polygonal slot and a regular polygonal block.

[0063] Preferably, the present design increases the thickness at the top bevel of the lipstick tube body 3, and the wall thickness of the lipstick tube body ranges from 1mm to 1.2mm; a circular arc R angle is set at the top of the lipstick tube body to transitionally connect with the side wall, which reduces sharp edges and increases the safety of the product.

[0064] Preferably, the first area 33 of the lipstick tube body 3 does not directly pass through the top of the lipstick tube body 3, and there is a distance between it and the top of the lipstick tube body 3. The second area 34 is between the top of the lipstick tube body 3 and the first area 33. The inner diameter of the second area 34 is smaller than the inner diameter of the first area 33. Because the outer diameter of the first area 33 matches the outer diameter of the head of the bead 4, the inner diameter of the second area 34 is smaller than the outer diameter of the head of the bead 4, which is equivalent to the cross-section of the lipstick head partially overlapping with the bead, which is equivalent to adding a limiting surface below the second area 34 to avoid idling of the sliding teeth when the bead 4 is rotated to the top, thereby increasing the upward force.

[0065] The working principle or working process of a lipstick tube provided by the utility model is as follows:

[0066] Method 1: Remove the outer cover 12, hold the lipstick tube body 3, and rotate the bottom cover 11 in the forward direction. The first limiting boss 22 on the bottom screw 2 is driven by the positive driving force of the third limiting groove 111 of the bottom cover 11, and the bottom screw 2 rotates in the forward direction. Since the bottom screw 2 and the transmission section of the bead 4 are threadedly matched, the bead 4 wants to spirally rise in the reverse direction. However, at this time, the first limiting member 51 in the lipstick tube body 3 applies a positive limiting force to the second limiting member 52 on the outer wall of the limiting section of the bead 4, and the bead 4 moves upward in a straight line along the axis of the lipstick tube body 3.

[0067] Similarly, the bottom cover 11 is rotated in the reverse direction, and the first limiting boss 22 on the bottom screw 2 is driven in the reverse direction by the third limiting groove 111 of the bottom cover 11, and the bottom screw 2 is rotated in the reverse direction. Since the bottom screw 2 is threadedly matched with the transmission section of the bead 4, the bead 4 is about to spirally descend in the positive direction, but at this time, the first limiting member 51 in the lipstick tube body 3 applies a reverse limiting force to the second limiting member 52 on the outer wall of the limiting section of the bead 4, and the bead 4 moves linearly downward along the axis of the lipstick tube body 3;

[0068] Method 2: Remove the outer cover 12, hold the bottom cover 11, and rotate the lipstick tube body 3 in the reverse direction. The first stopper 51 of the lipstick tube body 3 applies a reverse driving force to the second stopper 52 of the bead 4, and the bead 4 matched with the thread of the bottom screw 2 rises in the reverse spiral under the action of the reverse driving force.

[0069] Similarly, the lipstick tube body 3 is rotated forward, and the first limit piece 51 of the lipstick tube body 3 applies a positive driving force to the second limit piece 52 of the bead 4, and the bead 4 matched with the thread of the bottom screw 2 spirals downward in the forward direction under the action of the positive driving force.

[0070] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
