[0002] Lipstick is a commonly used cosmetic product, mainly composed of a packaging tube and the paste inside. The structural design of the packaging tube determines the comfort of lipstick use. The traditional lipstick packaging tube is generally composed of a cover, a bottom and a middle bundle core, among which the middle bundle core is the most critical component, which includes beads, forks, spiral tubes and middle bundles, and the four components are coaxially inserted together. The outer wall of the bead has symmetrically arranged protrusions, the fork has an axially arranged notch, and the inner wall of the spiral tube has a spiral tube-shaped guide groove, the protrusion passes through the notch and extends into the guide groove, the middle bundle and the spiral tube are fixedly inserted together, and the bottom is fixedly connected to the fork. When the fork and the spiral tube rotate relative to each other, the bead moves along the axial notch, thereby delivering the paste.

[0003] With the development of the times, society now has increasingly stringent requirements for such products. For example, the new law implemented in Europe in 2025, the Packaging and Packaging Waste Regulation (PPWR), imposes strict requirements on packaging materials, aiming to reduce the impact of packaging on the environment and promote a circular economy. However, the existing lipstick tubes have different materials for various components, and are affected by the process during production and processing. For example, the middle beam and the rotation need to be glued together, so they need to be split into corresponding materials when recycled. Therefore, the market needs a lipstick tube that is easy to produce, environmentally friendly and easy to recycle. Utility Model Content

DETAILED DESCRIPTION

[0038] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] Embodiment 1

[0040] like Figure 1-Figure 3 As shown, the purpose of the utility model is to provide a lipstick tube, which solves the problem that the lipstick tube is inconvenient to produce and assemble and difficult to recycle.

[0041] In order to achieve the above-mentioned purpose, the utility model provides a lipstick tube, including a middle bundle 1, a spiral tube 2, a lipstick embedding seat 3 and a fork 4, the fork 4 includes a connecting column 40 and a connecting seat 41 fixedly connected to the connecting column 40, the connecting column 40 is provided with a hollow guide groove 401, the diameter of the connecting seat 41 is larger than the connecting column 40, the outer wall of the lipstick embedding seat 3 is provided with a sliding member 30, the inner wall of the spiral tube 2 is provided with a spiral guide groove 21, the spiral tube 2 is inserted into the middle bundle 1, the connecting column 40 is inserted into the spiral tube 2, and the lipstick embedding seat 3 is in the connecting column 40. The sliding member 30 passes through the hollow guide groove 401 and abuts against the spiral guide groove 21; a notch 402 is provided at the opening of the upper end of the connecting column 40 and a convex edge 403 is provided on the outer wall of the upper end; the outer wall of the convex edge 403 is an inclined surface; after the middle bundle 1 is connected to the spiral tube 2, a buckling space 10 is formed at the upper end of the middle bundle 1; the convex edge 403 is in the buckling space 10 and abuts against the upper end surface of the spiral tube 2; the connecting seat 41 abuts against the lower end surface of the middle bundle 1; when working, the fork 4 is rotated, and the connecting column 40 rotates along the spiral guide groove 21, driving the lipstick embedding seat 3 to move up and down. The utility model provides a notch 402 so that the upper end of the connecting column 40 has a contraction margin. Therefore, during assembly, the upper end of the connecting column 40 can be slightly contracted or expanded, which facilitates the placement of the lipstick insert 3 in the connecting column 40 and the insertion of the connecting column 40 in the spiral tube 2. At the same time, since the convex edge 403 on the outer wall of the upper end of the connecting column 40 is not inclined, the upper end is guided to shrink inward during insertion, which further facilitates assembly. At the same time, the design of the convex edge 403 can also provide further rigid support for the upper end of the connecting column 40, ensuring that the wall surface can be restored in time after the notch 402 shrinks, thereby ensuring product stability.

[0042] At the same time, the spiral tube 2 and the middle bundle 1 are split designs. Since the plastic parts will shrink to a certain extent when cooled after injection molding, the middle bundle 1 can be designed to form a tight fit with the spiral tube 2 after shrinking, without the need for gluing, which is more environmentally friendly. Compared with the one-piece molding design, the split design of the utility model can prevent the spiral tube 2 from shrinking and deforming due to thread shrinkage after shrinking due to cooling, and can well ensure smooth rotation and improve product quality. Furthermore, the one-piece molded middle bundle 1, affected by its mold process, will result in a relatively narrow snap-fitting space 10. After the split design, a larger snap-fitting space 10 (such as Figure 4 As shown in FIG. 4 ), it is beneficial to connect the flange 403 with the spiral tube 2, making the buckling contact surface larger, thereby obtaining a better fastening connection. Under the mutual restriction of the flange 403 and the connecting seat 41, the fork 4 can be tightly fixed to the spiral tube 2, which can effectively prevent it from falling off during use and is more stable.

[0043] In addition, since the middle bundle 1, the spiral tube 2, the lipstick embedding seat 3 and the fork 4 of the lipstick tube are all made of the same material, there is no need to separate and classify them when recycling, making recycling more convenient and simple.

[0044] Furthermore, the notch 402 of the present invention is connected to the hollow guide groove 401 (see Figure 2 ). By connecting the notch 402 with the hollow guide groove 401, a larger shrinkage space is obtained, and since the connecting member slides in the hollow guide groove 401, even if the upper end of the connecting column 40 cannot be restored in time after being squeezed, when the connecting member moves in the hollow guide groove 401 and approaches the upper end of the connecting column 40, the wall surface can be restored under the squeezing effect of the lipstick embedding seat 3.

[0045] like Figure 5 As shown, a plurality of spring plates 31 are provided at the lower end of the lipstick mounting seat 3, and a protrusion 32 is provided on the outer wall of the spring plates 31, and the protrusion 32 abuts against the inner wall of the fork 4. Since the spring plates 31 and the protrusion 32 have a mutual squeezing force with the inner wall of the fork 4, when the lipstick mounting seat 3 slides, its lower end and the fork 4 can form a force balance, thereby causing the lipstick mounting seat 3 to shake, thereby improving the user's product experience.

[0046] Furthermore, the protrusions 32 are arranged at intervals on the elastic sheet 31, that is, the elastic sheet 31 provided with the protrusions 32 has two adjacent elastic sheets 31 without the protrusions 32. The protrusions 32 arranged at intervals can prevent the lipstick embedding seat 3 from slowing down, and can also avoid the problem of inconvenience in rotation due to excessive squeezing force.

[0047] like Figure 2 , Figure 6As shown, elastic sheets 404 are provided at annular intervals on the connecting column 40, and a tube positive groove 22 is provided at the lower end of the spiral tube 2, and the elastic sheets 404 are connected to the tube positive groove 22. Since there is a gap between the connecting column 40 and the spiral tube 2, it is easy to shake when rotating. Therefore, the utility model can correct the connecting column 40 by providing a plurality of elastic sheets 404. Since the elastic sheets 404 are relatively thin, they can be deformed during the connection process, thereby filling the gap between the connecting column 40 and the threaded tube, and playing a correction role.

[0048] Furthermore, a plurality of circular holes 405 are provided on the connecting column 40, through which a small amount of lubricating oil can be stored. Therefore, the lipstick embedding seat 3 can continuously replenish lubrication when moving, preventing the lubricating oil from being consumed after being scraped multiple times, and also helping to reduce the amount of lubricating oil used, which is more in line with the concept of environmental protection.

[0049] Embodiment 2

[0050] like Figure 7-Figure 9 As shown, the other structures of the lipstick tube are the same as those of the first embodiment, but the hollow guide groove 401 includes an upper ring groove 4011, a radial groove 4012 and a lower ring groove 4013. The upper ring groove 4011 is located at the upper end of the connecting column 40. The radial groove 4012 is provided with two channels and is respectively connected to the two ends of the upper ring groove 4011. The lower ring groove 4013 is located at the lower end of the connecting column 40. The radial groove 4012 is connected to the two ends of the lower ring groove 4013. A sliding member 30 and a stabilizing member 33 are provided on the outer wall of the lipstick embedding seat 3. The stabilizing member 33 abuts against the inner wall of the connecting member. Two spiral guide grooves 21 are provided in the spiral tube 2, and the spiral guide grooves 21 are symmetrically connected. The upper ring groove 4011, the radial groove 4012 and the lower ring groove 4013 of the utility model are connected to each other to form a coherent channel. Since the spiral guide grooves 21 are symmetrically arranged and connected to each other, the connecting column 40 can move up and down in a unified rotation direction. The stabilizing member 33 is spherical and can stabilize the lipstick mounting seat 3, making it more stable when moving.

[0051] Specifically, when the connecting column 40 moves upward through the spiral guide groove 21 and the radial groove 4012 and moves to the upper annular groove 4011, the connecting column 40 reaches the intersection of the upper ends of the spiral guide groove 21, and the connecting column 40 also enters the upper annular groove 4011. Since the upper annular groove 4011 surrounds the upper end of the connecting column 40 and has no space to move downward, the connecting column 40 will temporarily stay at the intersection of the two spiral guide grooves 21 and slide in the upper annular groove 4011 under force until it slides to the intersection of the upper annular groove 4011 and another radial groove 4012. When the connecting column 40 reaches the intersection of the upper annular groove 4011 and another radial groove 4012, the connecting column 40 will switch to another spiral guide groove 21, and the connecting column 40 will also enter another radial groove 4012 to obtain space to move downward. Therefore, the utility model can realize the up and down movement of the lipstick embedding seat 3 in the same rotation direction, making the use of lipstick more convenient.

[0052] Furthermore, the upper annular groove 4011 and the lower annular groove 4013 are respectively provided with convex points 4014, and the convex points 4014 are connected to the sliding member 30. The utility model uses the convex points 4014 to make the sliding member 30 produce a slight damping feeling when sliding in the upper annular groove 4011 and the lower annular groove 4013, which can improve the user's feel, and at the same time, the user can feel the moving position of the lipstick embedding seat 3 to avoid over-movement.

[0053] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
