Description

Technical Field

[0001] This utility model relates to lipstick, and more particularly to a multi-color integrated lipstick. Background Technology

[0002] Lipstick, as a cosmetic widely used in lip makeup, has a broad user base. Currently, most lipstick products on the market adopt a single tube and single color design. If a specific color or multi-layered makeup effect is required, users need to use multiple lipsticks to mix colors, which increases the difficulty of carrying and operation.

[0003] Lipstick is prone to coming off during daily activities, such as eating, drinking, and friction or contact during conversation. When lips are dry, the stratum corneum easily absorbs lipstick ingredients, causing the color to fade, thus requiring more frequent reapplication.

[0004] Furthermore, lipstick shades need to match the face makeup color, but face makeup products are prone to oxidation and discoloration after use, causing the initially matched lipstick shade to no longer match after oxidation. Therefore, multi-color lipsticks have emerged. The current market application of multi-color lipsticks is to achieve a sense of layering through color stacking, meeting the personalized makeup needs of a single product. However, their structural design usually uses a single-tube shell, manufactured through a one-piece molding process for multiple colors, and is marketed as gradient lipsticks. The content of colorants, pearlescent pigments, and other ingredients varies among different colors, leading to cracking at the interface, affecting product lifespan and brand reputation. Users need to accurately align the multi-color lipstick with the application area. Due to uneven usage frequency of each color, long-term use can cause uneven wear on one side of the lipstick, leading to tilting and breakage, reducing product lifespan and impacting user experience.

[0005] Traditional lipsticks typically use a twist-and-release mechanism with a smooth surface. Since lipstick is the final step in the makeup routine, residual foundation, sunscreen, and other oily cosmetics on the user's fingers can easily contaminate the casing, causing it to slip during the twisting process. This design flaw has long negatively impacted the user experience and remains a pressing issue for the industry. Utility Model Content

[0006] To address the shortcomings of the aforementioned technologies, this invention provides a multi-color integrated lipstick.

[0007] To solve the above technical problems, the technical solution adopted by this utility model is: a multi-color integrated lipstick, including a tube shell with openings at both ends, a main lipstick cap and a secondary lipstick receiving seat respectively fitted at the openings at both ends of the tube shell, a guide window opened on the tube shell, a rotating extension unit that can rotate relative to it and processes the main lipstick inside the tube shell, a movable rack that movably abuts against the rear side of the rotating extension unit, the movable rack engaging a toggle unit that is actuated by external force, the toggle unit being implemented by extending its toggle rod out of the guide window, and the secondary lipstick receiving seat containing the secondary lipstick.

[0008] Furthermore, the tube shell is cylindrical, and the maximum diameter of the front end of the tube shell that mates with the main ointment plug is adapted to the inner diameter of the main ointment plug.

[0009] Furthermore, the guide window is located in the middle of the tube shell in the form of a long strip and extends in the same direction along the length of the tube shell. On both sides of the guide window, there are a first receiving groove column and a second receiving groove column that are integral with the tube shell and extend outward.

[0010] Furthermore, an opening is provided on the opposite side of the guide window to penetrate the housing and connect the pin.

[0011] Furthermore, the first and second receiving groove columns are coaxially arranged and both are hollow structures, with a through hole on the free end face of the second receiving groove column.

[0012] Furthermore, the rotating extension unit includes an integrally machined first drive tube, a second drive tube, and a paste fixing head. The first drive tube, the second drive tube, and the paste fixing head are coaxially arranged and their maximum diameters decrease sequentially. The maximum diameter of the first drive tube is adapted to the inner wall diameter of the tube housing.

[0013] Furthermore, a spiral groove is provided on the outer wall of the first drive tube to accommodate the movement connection of the pin shaft;

[0014] The front end of the second drive tube has a limiting step with a maximum diameter greater than the maximum diameter of the main body of the second drive tube, and a spring is fitted on the main body of the second drive tube to axially limit movement within the tube housing.

[0015] Furthermore, the movable rack is located between the rotating extension unit and the secondary paste receiving seat.

[0016] Furthermore, the central part of the actuating unit is inserted into a shaft column that is rotatably connected within the first and second receiving slots. The shaft column has a hollow structure and a through hole is provided at its free end corresponding to the second receiving slot. A lip bar can be detachably inserted into the through hole.

[0017] Furthermore, the opposite side of the lever is machined with actuating teeth that mesh with the movable rack.

[0018] A multi-color, all-in-one lipstick replaces the traditional rotating operation with a reciprocating flicking motion, effectively preventing slippage caused by oily or cosmetic-laden hands. This allows for easy and precise one-handed control of the main lipstick's extension and retraction, significantly enhancing the user experience. Furthermore, the innovative design integrates the lip stick detachably into the pivot of the flicking unit, allowing for integrated storage of the secondary lipstick and application tool. This greatly facilitates easy access to the secondary lipstick for touch-ups, avoiding the problems of loss or contamination associated with external lip sticks in traditional designs.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-4 As shown in the illustration, this embodiment of the multi-color lipstick, compared to the traditional single-tube single-color lipstick, forms a single-tube multi-color design, such as... Figure 1As shown, this embodiment includes a tube shell 1 with openings at both ends. The openings at both ends of the tube shell 1 are respectively fitted with a main lipstick cap 2 and a secondary lipstick holder 3. The main lipstick cap 2 is designed the same as a traditional lipstick cap, ensuring the safety and cleanliness of the lipstick while retaining a similar method to traditional cap removal, making it convenient for consumers to use. The secondary lipstick holder 3 contains the secondary lipstick. In other words, the processing and position of the main lipstick are consistent with traditional lipsticks. However, considering the needs of usage frequency and portability, the secondary lipstick is designed to be smaller in capacity, similar to a traditional sample-sized color tester. The secondary lipstick holder 3 actually acts as an internal packaging box. To ensure a tight seal, a sealing ring 31 is provided on the outer wall of the secondary lipstick holder 3 to improve the sealing effect between the secondary lipstick holder 3 and the tube shell 1. It should be noted that during the production process, the manufacturer can adjust the color and texture of the main lipstick and the secondary lipstick as needed.

[0026] like Figure 1 As shown, the tube shell 1 is cylindrical. The maximum diameter of the front end of the tube shell 1 that mates with the main ointment stopper 2 is adapted to the inner diameter of the main ointment stopper 2. In other words, the tight fit between the tube shell 1 and the main ointment stopper 2 is ensured by processing the tube diameter. A guide window 13 is provided on the tube shell 1. The guide window 13 is located in the middle of the tube shell 1 in the form of a long strip and extends in the same direction along the length of the tube shell 1. On both sides of the guide window 13, there are a first receiving groove post 11 and a second receiving groove post 12 that are integral with the tube shell 1 and extend outward. The first receiving groove post 11 and the second receiving groove post 12 extend outward to the same length.

[0027] In this embodiment, the housing 1 is provided with a rotating extension unit 5 that is rotatably connected to and processes the main lipstick. That is to say, in this embodiment, the main lipstick is still screwed in or out by rotating extension. However, unlike the traditional method of twisting by hand, the rear side of the rotating extension unit 5 in this embodiment is equipped with a movable rack 7 that abuts against it. The movable rack 7 is engaged with a toggle unit 6 that is actuated by external force. In other words, this embodiment transforms the hand-twisting rotation into a reciprocating toggle operation, which can be completed by the consumer with one hand, making it faster. Even if there is residual foundation, sunscreen or other oily cosmetics on the fingers, it will not cause slippage during the rotation operation, and the force of the toggle operation is not affected, greatly improving the user experience of the main lipstick. Furthermore, the toggle unit 6 is implemented by extending its toggle rod 61 out of the guide window 13. The guide window 13 provides clearance for the reciprocating toggle of the toggle rod 61 by opening the window, which is convenient for the consumer to operate.

[0028] The guide window 13 has an opening on the opposite side that penetrates the tube housing 1 to connect the pin 4. The opening is not shown in the figure. Its purpose is to connect the pin 4 and allow the pin 4 to extend into the tube housing 1. In this embodiment, the pin 4 is fastened by adhesive bonding. However, this embodiment does not limit the connection method in actual manufacturing.

[0029] In this embodiment, the first receiving groove post 11 and the second receiving groove post 12 are coaxially arranged and both are hollow structures. The purpose of this design is to enable them to be movably connected to the toggle unit 6, and the free end face of the second receiving groove post 12 is provided with a through hole.

[0030] like Figure 2 As shown, the rotating extension unit 5 includes an integrally machined first drive tube 51, second drive tube 52, and lipstick fixing head 54. The first drive tube 51, second drive tube 52, and lipstick fixing head 54 are coaxially arranged and their maximum diameters decrease sequentially. The maximum diameter of the first drive tube 51 is adapted to the inner wall diameter of the tube shell 1, that is, it is built in a clearance fit manner. It should be noted that the lipstick fixing head 54 is used to insert into the inner liner where the main lipstick is placed. That is, the head of the lipstick fixing head 54 is inserted into the bottom recess of the inner liner where the main lipstick is placed. This is also the reason why the diameter of the lipstick fixing head 54 is the smallest. After the lipstick fixing head 54 is inserted into the inner liner, a glue seal can be formed at the joint to improve the stability of the connection. This embodiment does not limit the method of directly filling the lipstick into the mold and then cooling and shaping it on the lipstick fixing head 54, but in terms of service life, the connection between the lipstick fixing head 54 and the inner liner has a longer service life and stronger durability.

[0031] Preferably, a spiral groove 511 is formed on the outer wall of the first drive tube 51 to accommodate the movable connection of the pin 4. The spiral groove 511 is a common feature in traditional lipstick casings. In this embodiment, the spiral groove 511 serves as a motion trajectory in conjunction with the pin 4 to achieve the function of guiding the motion. Figure 2 As shown, both ends of the spiral groove 511 form a straight depth trajectory, which is used to prevent the rotating extension unit 5 from moving without force. This setting is also existing.

[0032] Preferably, the front end of the second drive tube 52 has a limiting step 521 with a maximum diameter larger than the maximum diameter of the main body of the second drive tube 52. It should be noted that the maximum diameter of the limiting step 521 gradually increases from its end to its root. A spring 53 is fitted on the main body of the second drive tube 52 and is axially limited inside the tube housing 1. The rear end of the limiting step 521 limits the corresponding end of the spring 53. After the rotating extension unit 5 rotates and extends to its maximum travel position, the front end of the limiting step 521 abuts against the inner wall of the front end of the tube housing 1 to limit the movement. Step 521 continues to extend. In other words, in order to prevent the second drive tube 52 from extending excessively, the inner part of the front end of the tube housing 1 forms a diameter smaller than that of the tube housing 1 and is adapted to the outer diameter of the root of the limiting step 521 to block it. It can be understood that the inner part of the front end of the housing 1 limits the root of the limiting step 521, and the rest of the limiting step 521 extends out of the tube housing 1. Then, when the rotating extension unit 5 rotates and extends to the maximum travel position, the spring 53 is compressed to obtain the elastic potential energy when resetting, which makes it easier for the consumer to apply force to trigger the toggle unit 6.

[0033] like Figure 2 As shown, the movable rack 7 is located between the rotating extension unit 5 and the secondary lipstick receiving seat 3. It should be noted that the movable rack 7 is blocked by the wall thickness of the secondary lipstick receiving seat 3 and will not damage the secondary lipstick inside the secondary lipstick receiving seat 3. When the actuating unit 6 moves, the movable rack 7, which meshes with the actuating unit 6, will change its position. Due to the relative limiting of the two, the movement of the movable rack 7 is stable sliding. However, if it is necessary to further enhance the stable reciprocating motion of the movable rack 7, a guide rib extending axially can be provided on the inner wall of the tube housing 1 so that the movable rack 7 can only move along the axial direction of the tube housing. The appropriate rib can be selected according to actual needs during manufacturing. This is hereby explained.

[0034] Based on the above structure and combined Figure 2-3 As shown, the central part of the actuating unit 6 is inserted into the shaft column 62, which is rotatably connected within the first receiving groove 11 and the second receiving groove 12. The actuating unit 6 can be actuated through the common connection between the shaft column 62 and the first receiving groove 11 and the second receiving groove 12. Preferably, the shaft column 62 is a hollow structure and has a through hole at its free end corresponding to the second receiving groove 12. A lip rod 8 is detachably inserted into the through hole. In order to improve the user experience of the auxiliary cream, the lip rod 8 is built into this embodiment. In order to further enhance the connection stability of the lip rod 8, a magnet is provided on the inner side of the end of the lip rod 8. Similarly, a magnet corresponding to the magnet of the lip rod 8 is provided on the free end face of the second receiving groove 12. That is to say, the connection stability is improved by magnetic attraction after the lip rod 8 is inserted to the bottom.

[0035] The opposite side of the lever 61 is machined with a lever tooth 63 that meshes with the movable rack 7.

[0036] The working principle of this embodiment is as follows: When a consumer wants to use the main cream, first remove the main cream cap 2, then apply force with their finger to push the lever 61 located at the front end of the guide window 13 backward. At this time, the lever 63 engages with the movable rack 7, and the movable rack 7 moves forward under the engagement to block the rotating extension unit 5 from moving forward. The spiral groove 511 of the first drive tube 51 and the pin 4 cooperate to rotate and extend. Similarly, to retract the main cream, apply force with your finger to push the lever 61 located at the rear end of the guide window 13 forward, thereby achieving the reset.

[0037] When consumers want to use the secondary lipstick, they first apply force to pull off the secondary lipstick holder 3, and then pull off the lip stick 8 to apply makeup.

[0038] This application discloses a multi-color integrated lipstick that replaces the traditional rotating operation with a reciprocating flicking operation, effectively avoiding the slippage problem caused by oily cosmetics on the hands. It allows for easy and precise one-handed control of the extension and retraction of the main lipstick, greatly improving the user experience. Furthermore, the innovative design integrates the lip stick detachably into the central axis of the flicking unit, allowing the secondary lipstick and application tool to be stored together, greatly facilitating users to easily access the secondary lipstick for touch-ups and avoiding the problems of loss or contamination associated with external lip sticks in traditional designs.

[0039] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
