Description

Technical Field

[0001] This invention belongs to the field of cosmetic packaging bottle technology, specifically a magnetic elastic lipstick tube. Background Technology

[0002] Lipstick is a commonly used cosmetic for women. Existing lipstick tubes generally include a shell, a core, and a cap. The cap is usually just an interference fit at the opening of the shell. When using it, the cap is removed and the core is rotated to push the lipstick out.

[0003] With the diversification of lipstick tubes, pop-up lipstick tubes have emerged. Unlike traditional lipstick tubes, the cap covers the original casing, while the casing and the core remain a single unit. To use, press the casing and core into the cap to pop them out; after use, press again to lock them back in. However, this existing lipstick tube structure is very complex, resulting in high manufacturing and assembly costs. Furthermore, shaking the casing and core causes internal components to wobble, producing a "clattering" noise that negatively impacts the user experience. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a magnetic elastic lipstick tube. This magnetic elastic lipstick tube can meet the usage requirements of pressing to pop out and pressing again to fasten, while having a simple structure, low manufacturing and assembly costs, and no abnormal noise when shaking the outer cover, providing a good feel and improving the user experience.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a magnetic elastic lipstick tube, comprising a lipstick tube body and a cap, wherein the cap has an opening, and the open end of the lipstick tube body is fitted into the opening. The cap includes an outer cap, a guide cylinder, a movable seat, a spring, a rotating component, and a limiting component. The guide cylinder is fixed within the cap, and the movable seat is axially slidably disposed within the guide cylinder. The spring is disposed between the movable seat and the bottom of the outer cap, and the bottom of the movable seat is fitted onto the outside of the top of the rotating component and limited by a limiting component. The positioning rings mutually limit each other. The rotating component has a first guide protrusion on its opposite sides. The side wall of the movable seat is provided with a spiral guide channel. The first guide protrusion is located in the spiral guide channel. The bottom of the rotating component and the bottom of the outer cover are respectively provided with an iron sheet and a magnet that can attract each other. When the first guide protrusion is located at the bottom of the spiral guide channel, the iron sheet and the magnet are aligned. The inner wall of the movable seat is provided with a protrusion for interference clamping the rotating component to drive it upward. The limiting component includes a hook for hooking the upward rotating component and disengaging it from the protrusion. In its unused state, this magnetic elastic lipstick tube is positioned within the movable base, with the outer end of the tube flush with the opening. The bottom of the rotating component aligns and engages with the metal plate and magnet on the bottom of the outer cover, and the spring is compressed. To remove the lipstick tube for use, press down on it. The movable base descends, and the first guide protrusion engages with the spiral guide channel, causing the rotating component to rotate. This causes the metal plate and magnet to shift, reducing their attractive force, and the rotating component is then held in place by the protrusion. Upon releasing the pressure, the spring force pushes the movable base upward, allowing the lipstick tube to extend from the opening and be pulled out. When the lipstick tube body is in use, as the movable base travels a certain distance, the rotating part is hooked by the pull hook, disengaging from the protrusion. The rotating part then rotates and moves down along the spiral guide channel from the first guide protrusion to the lowest point of the spiral guide channel. At this point, the iron plate and magnet are aligned again and have a certain attraction, preventing wobbling when the cap is shaken. After use, the lipstick tube body is re-inserted into the movable base and gently pressed until it is flush with the opening, causing the iron plate and magnet to re-engage. Due to the attraction between the iron plate and magnet, the user's feel is improved, returning it to its unused state. This magnetic elastic lipstick tube, while meeting the needs of pressing to pop out and pressing to lock, has a simple structure, low manufacturing and assembly costs, and does not produce abnormal noise when the outer cap is shaken, providing a good feel and enhancing the user experience.

[0006] In the above technical solution, preferably, the inner end of the guide cylinder is sealed, and the magnet and the limiting member are fixedly disposed on the inner end of the guide cylinder. This structure facilitates the installation and fixation of the magnet and the limiting member.

[0007] In the above technical solution, preferably, guide waist holes are provided on both sides of the guide cylinder, and second guide protrusions are provided on both sides of the movable seat, with the second guide protrusions passing through the guide waist holes. This structure facilitates the guidance of the movable seat and limits its travel.

[0008] In the above technical solution, preferably, at least one of the guide waist holes on the guide cylinder extends to the end through a gap with a width smaller than that of the guide waist hole. This structure facilitates the insertion of the movable seat into the guide cylinder.

[0009] In the above technical solution, preferably, the movable base has elastic protrusions on both sides, which elastically limit the lipstick tube body. This structure ensures that the lipstick tube body will not easily fall off after being inserted into the movable base.

[0010] Compared with the prior art, this invention has the following advantages: In its unused state, the lipstick tube body is located within the movable base, with the outer end of the lipstick tube body flush with the opening. The bottom of the rotating component aligns with and attracts the iron plate and magnet at the bottom of the outer cover, and the spring is compressed. When the lipstick tube body needs to be removed for use, pressing the lipstick tube body with your hand causes the movable base to descend. The first guide protrusion cooperates with the spiral guide channel, causing the rotating component to rotate. The iron plate and magnet are misaligned, reducing the attractive force, and the rotating component is held in place by the protrusion. After releasing the hand, the spring force pushes the movable base upward, allowing the lipstick tube body to... The lipstick tube extends from the opening, allowing the main body to be pulled out for use. When the movable base travels a certain distance, the rotating component is hooked by the pull hook, disengaging from the protrusion. The rotating component then rotates downwards along the spiral guide channel from the first guide protrusion to its lowest point. At this point, the metal plate and magnet align again and exert a certain attraction, preventing wobbling when the cap is shaken. After use, the lipstick tube is re-inserted into the movable base and gently pressed until it is flush with the opening, causing the metal plate and magnet to re-engage. The attraction between the metal plate and magnet improves the user's feel, returning the lipstick to its unused state. This magnetic elastic lipstick tube, while meeting the needs of pressing to pop out and pressing to re-lock, has a simple structure, low manufacturing and assembly costs, and produces no abnormal noise when the cap is shaken, providing a good feel and enhancing the user experience.

The guide cylinder 23 is fixed inside the cap 2, and the movable seat 24 is axially slidable inside the guide cylinder 23. A spring 25 is provided between the movable seat 24 and the bottom of the outer cap 22. The bottom of the movable seat 24 is fitted onto the outside of the top of the rotating component 26 and mutually limited by a limiting ring 28. That is, the bottom of the movable seat 24 is provided with a limiting ring 28 facing inward, and the top of the rotating component 26 is provided with a limiting ring 28 facing outward. A limiting ring 28 is provided. First guide protrusions 261 are provided on opposite sides of the rotating component 26. A spiral guide channel 241 is provided on the side wall of the movable seat 24. The first guide protrusions 261 are located within the spiral guide channel 241. Iron plates 3 and magnets 4 that can attract each other are respectively provided at the bottom of the rotating component 26 and the bottom of the outer cover 22. When the first guide protrusion 261 is located at the bottom of the spiral guide channel 241, the iron plates 3 and magnets 4 are aligned. In this embodiment, the bottom of the rotating component 26 is provided with a fixed iron plate 3, and the bottom of the outer cover 22 is provided with a magnet 4. Of course, in other embodiments, the installation positions of the iron plates 3 and magnets 4 can be interchanged, or both can use magnets 4. The inner wall of the movable seat 24 is provided with a protrusion 243 for interference-locking the rotating component 26 to drive it upward. The limiting member 27 includes a hook 271 for hooking the upward-moving rotating component 26 and disengaging it from the protrusion 243.

[0017] In its unused state, the lipstick tube body 1 is located inside the movable base 24, with the outer end of the lipstick tube body 1 flush with the opening 21. The bottom of the rotating part 26 aligns and attracts the iron plate 3 and magnet 4 at the bottom of the outer cover 22, and the spring 25 is compressed. When the lipstick tube body 1 needs to be removed for use, the lipstick tube body 1 is pressed by hand, the movable base 24 moves downward, and the first guide protrusion 261 cooperates with the spiral guide channel 241 to make the rotating part 26 rotate. The iron plate 3 and magnet 4 are misaligned, reducing the attraction force, and the rotating part 26 is stuck by the protrusion 243. After releasing the hand, the elastic force of the spring 25 pushes the movable base 24 upward, allowing the lipstick tube body 1 to extend out of the opening 21 and be pulled out. When the lipstick tube body 1 is in use, as the movable seat 24 moves upward to a certain distance, the rotating part 26 is hooked by the hook 271, disengaging from the protrusion 243. The rotating part 26 then rotates downward along the spiral guide channel 241 from the first guide protrusion 261 to the lowest point of the spiral guide channel 241. At this point, the iron plate 3 and the magnet 4 are aligned again and have a certain attraction, preventing shaking when the cap 2 is shaken. After use, the lipstick tube body 1 is re-inserted into the movable seat 24 and gently pressed until it is flush with the opening 21, causing the iron plate 3 and the magnet 4 to re-attract. The attraction between the iron plate 3 and the magnet 4 improves the user's feel, returning the lipstick tube to its unused state. This magnetic elastic lipstick tube, while meeting the requirements of pressing to pop out and pressing to re-lock, has a simple structure, low manufacturing and assembly costs, and produces no abnormal noise when the cap is shaken, providing a good feel and enhancing the user experience.

[0018] In this embodiment, the inner end of the guide cylinder 23 is sealed, and a magnet 4 and a limiting member 27 are fixedly installed inside the guide cylinder 23. This structure facilitates the installation and fixation of the magnet 4 and the limiting member 27.

[0019] In this embodiment, guide holes 231 are provided on both sides of the guide cylinder 23, and second guide protrusions 242 are provided on both sides of the movable seat 24, with the second guide protrusions 242 passing through the guide holes 231. This structure facilitates the guidance of the movable seat 24 and limits the movement stroke of the movable seat 24.

[0020] In this embodiment, at least one of the guide waist holes 231 on the guide cylinder 23 extends to the end through a gap 232 with a width smaller than that of the guide waist hole 231. This structure facilitates the insertion of the movable seat 24 into the guide cylinder 23.

[0021] In this embodiment, elastic protrusions 244 are provided on both sides of the movable base 24, and the elastic protrusions 244 elastically limit the lipstick tube body 1. This structure ensures that the lipstick tube body 1 will not easily fall off after being inserted into the movable base 24.

[0022] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
