[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides a lip gloss bottle that, through an internal transmission structure, automatically stirs the lip gloss inside the bottle during the user's regular application, thereby preventing pigment precipitation and oil-liquid phase separation, and ensuring that the amount of product dispensed each time is uniform and the color is consistent.

[0035] Specifically, such as Figures 1 to 9 As shown, the lip gloss bottle mainly includes a cap 100, a rod 200, a bottle body 500, an inner plug 300, a guide 400, and a piston 41.

[0036] like Figure 3 As shown, the cover 100 is typically circular, square, or polygonal, and can be made of materials such as plastic, metal, or glass. The cover 100 has an internal connecting structure for fixed connection with the rod 200. In this embodiment, the cover 100 is a square structure. A first limiting plate 11 is provided at the included angle between two adjacent end faces of the cover 100, and the inner wall of the cover 100 is provided with protruding ribs 12 for engaging with the rod 200.

[0037] like Figure 4As shown, the rod 200 is integrally formed or fixedly connected to the rod portion 21 and the brush head 22. A base 23 is also provided at one end of the rod portion 21. The base 23 is pushed in along the inner wall of the cap 100 and presses against the protruding rib 12, causing the base 23 to engage with the cap 100. Multiple second limiting plates 24 are provided on the outer surface of the base 23. When the base 23 is assembled with the cap 100, the slots 25 formed by the two second limiting plates 24 are matched with the first limiting plate 11 to prevent the rod 200 from rotating during use, which would make application difficult and result in a poor user experience. An internal thread 26 is provided on the inner wall of the base 23 for screwing into the bottle 500.

[0038] The aforementioned rod 21 is a stepped shaft structure that is thicker at the top and thinner at the bottom. Its lower part extends into the interior of the bottle body 500. The brush head 22 is usually made of fiber bristles, elastic silicone, or food-grade stainless steel. Its outer diameter is smaller than the outer diameter of the rod 21 and smaller than the outer diameter of the lower end of the rod 21, so as to be able to reach into the bottle body 500 to pick up the material. On the outer peripheral wall of the lower end of the rod 21, there are multiple outwardly protruding protrusions 211 distributed in a ring. These protrusions 211 can be hemispherical, wedge-shaped, or trapezoidal blocks. The protrusions 211 are used to engage with the piston 41 to form a transmission connection.

[0039] like Figure 2 As shown, the bottle body 500 is used to contain the lip gloss material, and an inner stopper 300 is press-fitted or bonded to its mouth. The inner stopper 300 is usually made of an elastic material, such as food-grade silicone or PTE material. Of course, other materials can also be selected for the inner stopper 300 as needed. It has a through hole 31 in the center for the rod 200 to pass through. The through hole 31 is interference-fitted with the rod 21 of the rod 200, which serves to seal and scrape off the material. When the rod 200 is lifted or pressed down, the inner stopper 300 can effectively scrape off excess material on the rod 21, ensuring that the brush head 22 is coated with an appropriate amount of material and the bottle mouth is clean, preventing leakage. The outer side of the bottle mouth of the bottle body 500 is provided with an external thread 51 that mates with the internal thread 26 of the cap 100.

[0040] A rotatable guide 400 is provided inside the bottle body 500, and a small gap may exist between its outer wall and the inner wall of the bottle body 500 to achieve rotational support. The guide 400 includes a plurality of stirring parts 42 arranged along the axial direction. In this embodiment, two first stirring parts 421 and second stirring parts 422 with different structures are used as examples for description.

[0041] Among them, such as Figure 2 , 7As shown in Figure 8, the first stirring part 421 includes a first limiting part 4211 and a second limiting part 4212 located at its upper and lower ends, respectively. Two arc-shaped frames 4213 are connected between the first limiting part 4211 and the second limiting part 4212. The two frames 4213 are arranged opposite to each other, forming a guide space between them. Each frame 4213 has a guide groove 4214 on its body, which extends through the thickness direction of the frame 4213. In this embodiment, the guide groove 4214 is a curved arc-shaped groove. A reinforcing rib 4215 connects the two frames 4213. The reinforcing rib 4215 includes an oblique rib 4215a connecting the connection between the first limiting part 4211 and the upper end of one frame 4213, and the connection between the second limiting part 4212 and the lower end of the other frame 4213, as well as a transverse rib 4215b connecting the middle position of the two frames 4213. The oblique ribs 4215a and transverse ribs 4215b divide the space between the two frames 4213 into multiple guide ports 4216 of varying sizes. The material can flow through these guide ports 4216 and the through channels during mixing, enhancing the mixing effect. The angle between the oblique ribs 4215a and the axial direction is preferably 30°-70° to generate optimal axial flow diversion and radial shear force on the material during rotation.

[0042] The second stirring section 422 is located below the first stirring section 421. One end of it is a support section 4221 for support, and the support section 4221 is connected to the upper second limiting section 4212 through a guide frame 4222. The guide frame 4222 includes multiple vertical ribs 4222a, and adjacent vertical ribs 4222a are connected by horizontal ribs 4222b, thereby forming a grid-like structure and creating multiple large number of guide ports 4223, which disperse any vortices that may be formed during rotation, providing a finer mixing effect.

[0043] In addition, the structural differences between the first stirring section 421 and the second stirring section 422 cause them to agitate the material in different ways, thereby achieving more thorough mixing.

[0044] like Figure 2 , 6 As shown, piston 41 is disposed on the first stirring part 421 of guide member 400. Piston 41 includes a main body 411 with a mounting hole 4111 for inserting rod 200. The main body 411 is an annular ring with a plurality of engaging parts 412 circumferentially distributed on the outer peripheral wall of the annular ring. The engaging parts 412 slide with guide grooves 4214, and a notch 413 is formed between every two engaging parts 412. Guide blocks 414 are further correspondingly provided on at least two opposing engaging parts 412, and the shape of the guide blocks 414 is adapted to the shape of the guide grooves 4214. The upper and lower ends of the inner ring of the main body 411 are chamfered or rounded, thereby forming an annular flange 4112 in the middle of its inner wall.

[0045] The piston 41 is engaged in the guide groove 4214 of the first stirring part 421 via the guide block 414 thereon, and can slide along the path of the guide groove 4214. The axial movement of the piston 41 is restricted between the first limiting part 4211 and the second limiting part 4212, that is, when the piston 41 moves to the top dead center, its top contacts the first limiting part 4211; when it moves to the bottom dead center, its bottom contacts the second limiting part 4212.

[0046] After the rod portion 21 of the rod 200 passes through the inner plug 300, the protrusion 211 at its lower end is forced through the flange 4112 on the inner wall of the piston 41 ring, and finally engages with the flange 4112. That is, the flange 4112 is locked above the protrusion 211 under the action of elastic restoring force, thus forming a reliable transmission connection. The cap 100 is connected to the bottle body 500 by threads.

[0047] When the user unscrews the cap 100 and lifts the lever 200, the lever 200 engages with the flange 4112 of the piston 41 via its protrusion 211, causing the piston 41 to move upwards. Since the guide block 414 of the piston 41 is engaged within the fixed guide groove 4214, the upward linear motion of the piston 41 is constrained by the trajectory of the guide groove 4214 and converted into a rotational force on the guide 400, thereby driving the entire guide 400 (including the first stirring part 421 and the second stirring part 422) to rotate within the bottle 500. During this process, the brush head 22 is pulled out of the bottle opening, while the rotating stirring part 42 simultaneously stirs the contents of the bottle. Conversely, when the user presses down the lever 200 and closes the cap 100, the process is reversed; the guide 400 rotates in the opposite direction, stirring again.

[0048] In this embodiment, the user's linear lifting action is automatically converted into the rotational motion of the internal stirring component, achieving the effect of "one lift and one pull, instant mixing," effectively solving the problem of lip gloss sedimentation and improving the user experience. At the same time, the guide block 414 of the piston 41 engages with the guide groove 4214, improving the stability of the overall structure and preventing loosening or misalignment.

[0049] like Figure 9 As shown, in another embodiment, the usage is the same as in the above embodiment, except that the chute can also be a straight chute, and the straight chute is formed by two straight frames 4213. When the lifting rod 200 is lifted, the upward linear movement of the piston 41 is not constrained by the trajectory of the guide groove 4214. A rotational force must be applied at the same time as lifting the rod 200 to make the guide 400 rotate, which can also make the material in the bottle 500 evenly stirred.

[0050] In another embodiment not shown, the guide member 400 includes only a single stirring section 42. This stirring section 42 may also have the frame 4213 structure of the first stirring section 421 or the mesh structure of the second stirring section 422, or it may be designed to contain only paddle-shaped, spiral-shaped, or other shaped stirring elements depending on the material characteristics (such as viscosity and particle content). As long as it can cooperate with the piston 41 to achieve motion conversion and perform a stirring function, it falls within the protection scope of this utility model.

[0051] like Figure 10 As shown, in another embodiment, only a single stirring section 42 is included. This stirring section 42 can also incorporate the reinforcing ribs 4215 structure of the first stirring section 421, or it can be formed into different forms of mesh structures through the combination of arc-shaped ribs and transverse ribs, making the structure simple and easy to manufacture. The stirring section 42 is interference-fitted with the rod 200, allowing the stirring section 42 to move with the rod 200, pulling the rod 200 up and down and rotating, thus driving the stirring section 42 to move up and down and rotate. This process ensures thorough mixing of the material, and the fit between the rod 200 and the stirring section 42 is relatively stable and secure.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
