A lip gloss bottle

Abstract

This utility model relates to the field of cosmetic technology, specifically disclosing a lip gloss bottle, including a bottle body and an outer shell mounted on the bottle body, and a brush head disposed inside the outer shell via an installation unit. A stirring component is disposed inside the bottle body, and the brush head is connected to the stirring component to drive the stirring component to rotate and slide inside the bottle body. Rigid transmission between the brush head and the stirring component avoids the phenomenon of idling due to excessive resistance when rotating and stirring thick materials. Simultaneously, the stirring piston, guided by the inner plug contact surface, can achieve a combined rotational and sliding motion, ensuring that even when the material is thick, it can smoothly sink to the bottom of the bottle under its own weight and the drive of the brush head, thereby achieving thorough and uniform stirring of the material inside the bottle from top to bottom, preventing the problem of stirring dead zones caused by the floating of the stirring component.

Description

Technical Field

[0001] This utility model relates to the field of cosmetics technology, specifically to a lip gloss bottle. Background Technology

[0002] Lip gloss is a type of lip makeup product that can achieve effects that lipsticks and lip glosses cannot. Lip gloss combines the saturated color of lipstick with the glossy texture of lip gloss, easily achieved with just a light swipe. Unlike lipsticks, lip gloss has a certain degree of fluidity and viscosity.

[0003] Existing technologies, such as the Chinese patent with authorization announcement number CN216753775U entitled "A Lip Gloss Bottle," disclose a lip gloss bottle comprising a bottle body and a cap movably connected to the bottle body. A sliding groove is formed on the inner wall of the bottle body, and a scraping mechanism cooperating with the sliding groove is provided inside the bottle body. The scraping mechanism includes a turntable and scraping rods disposed opposite each other on both sides of the turntable and fixedly connected to the turntable. A connection port is formed through the turntable, and at least one fitting block is provided at the connection port. A brush rod is fixedly connected to the cap, and a locking block cooperating with the fitting block is fixedly connected to the brush rod. Existing technologies, including the aforementioned patent, can meet users' needs to a certain extent.

[0004] In existing technologies, to meet the stirring requirements of lip gloss liquid, a brush head is usually used to drive a stirring component to stir the product liquid. However, in actual use, the following problems still exist: 1. When the product is too thick, the stirring component may not be able to sink to the bottom of the bottle completely on its own (it may remain suspended inside the bottle), resulting in insufficient mixing of the material during use.

[0005] 2. Furthermore, during the rotation process, the viscous material presents greater resistance, and relying solely on the tight fit or strong interference between the brush head and the mixing components can easily lead to idling. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] Please see Figures 1-10 This utility model provides a technical solution: a lip gloss bottle, including a bottle body 6 and a shell 1 installed on the bottle body 6, and a brush head 31 installed inside the shell 1 through an installation unit. A stirring component is provided inside the bottle body 6, and the brush head 31 is connected to the stirring component to drive the stirring component to rotate and slide inside the bottle body 6.

[0028] Specifically, the lip gloss bottle includes a bottle body 6 and an outer shell 1 mounted on the bottle body 6. The outer shell 1 is typically round, square, or polygonal and can be made of materials such as plastic, metal, or glass. It also includes a brush head 31 mounted inside the outer shell 1 via an installation unit. The brush head 31 is typically made of fiber bristles, elastic silicone, or food-grade stainless steel. A stirring component is installed inside the bottle body 6, and the brush head 31 is connected to the stirring component to drive the stirring component to rotate and slide inside the bottle body 6. During the user's regular application, the product is automatically stirred inside the bottle, thus preventing pigment sedimentation and oil-liquid phase separation, ensuring that the product dispensed is uniform in consistency and color.

[0029] In the embodiments provided by this utility model, the installation unit includes an inner mounting cover 7 disposed inside the outer casing 1. The inner mounting cover 7 is connected to the outer casing 1 via a positioning part, and a brush rod 2 is disposed on the inner mounting cover 7. The inner mounting cover 7 serves as an intermediate fixing structure, which not only improves the installation stability of the brush rod 2 but also facilitates overall assembly and maintenance. Simultaneously, the design of the positioning part ensures a secure connection between the inner mounting cover 7 and the outer casing 1, preventing loosening during use from affecting the transmission efficiency of the brush head 31 and the stirring component.

[0030] In the embodiment provided by this utility model, a mounting groove 21 is provided at the bottom of the brush rod 2, and a mounting rod 32 is fixedly connected to the brush head 31, with the mounting rod 32 engaging with the mounting groove 21. The engaging design of the mounting groove 21 and the mounting rod 32 is simple in structure and easy to install and remove, improving the replaceability and maintainability of the brush head 31. Furthermore, the engaging connection ensures the transmission rigidity between the brush head 31 and the brush rod 2, preventing loosening or detachment during the stirring process.

[0031] In the embodiments provided by this utility model, the stirring component includes a stirring piston 5, and a brush head 31 is engaged with the inner wall of the stirring piston 5. The stirring piston 5, as a specific implementation of the stirring component, forms a rigid connection with the inner wall of the brush head 31, effectively transmitting rotational torque, preventing slippage or idling in high-viscosity materials, and further improving the efficiency of stirring the liquid inside the bottle 6.

[0032] In the embodiments provided by this utility model, reinforcing ribs 10 are fixedly connected to both sides of the inner wall of the stirring piston 5, and the brush head 31 is engaged with the reinforcing ribs 10 on both sides. The reinforcing ribs 10 not only enhance the structural strength of the stirring piston 5 and prevent it from deforming under force, but also increase the contact area with the brush head 31, making the engagement tighter and further preventing dry running.

[0033] In the embodiments provided by this utility model, an extension head 61 is provided on the bottle body 6, and an inner plug 4 is provided on the extension head 61. The inner plug 4 is usually made of food-grade silicone or PTE material, and the stirring piston 5 intermittently abuts against the inner plug 4. Preferably, a through groove 41 is provided at the bottom of the inner plug 4, the brush rod 2 is slidably connected to the through groove 41, and an abutment surface 42 is provided at the bottom of the inner plug 4, through which the stirring piston 5 intermittently abuts against the inner plug 4. When it is necessary to pull the brush head 31 out of the inner plug 4, the stirring piston 5 will abut against the bottom of the inner plug 4, so that the stirring piston 5 is disengaged from the brush head 31.

[0034] In the embodiments provided by this utility model, the positioning part includes a plurality of abutment strips 9 fixedly connected inside the outer shell 1. After the inner cover 7 is installed inside the outer shell 1, the plurality of abutment strips 9 abut against the inner cover 7. The abutment strips 9 have a simple structure and are easy to install. They can effectively limit the displacement of the inner cover 7 inside the outer shell 1 and prevent it from shaking or rotating during use.

[0035] In the embodiments provided by this utility model, a plurality of limiting parts are further provided between the outer shell 1 and the inner cover 7. The limiting parts include a first limiting strip 13 fixedly connected to the outer shell 1, and two second limiting strips 12 fixedly connected to the inner cover 7. When the inner cover 7 is installed inside the outer shell 1, the first limiting strip 13 is engaged with the two second limiting strips 12. Through the engaging cooperation between the first limiting strip 13 and the second limiting strips 12, the connection between the inner cover 7 and the outer shell 1 is further strengthened, preventing it from loosening during rotation or vibration, and ensuring the accurate positioning of the brush rod 2 and the brush head 31.

[0036] In the embodiment provided by this utility model, an anti-rotation part 8 is also provided between the inner cover 7 and the extension head 61. The anti-rotation part 8 includes a limiting block 83 fixedly connected to the extension head 61, and the inner cover 7 is provided with a wedge-shaped abutment block 81 and a positioning block 82. When the outer shell 1 and the bottle body 6 are closed, the limiting block 83 is engaged between the positioning block 82 and the wedge-shaped abutment block 81. The anti-rotation part 8 effectively prevents relative rotation between the inner cover 7 and the extension head 61, ensuring that the brush head 31 and the stirring piston 5 are always aligned. When it is necessary to separate the inner cover 7 from the extension head 61, the inner cover 7 is rotated so that the wedge-shaped abutment block 81 on the inner cover 7 contacts and presses against the wedge-shaped surface on the limiting block 83 until the restriction on the limiting block 83 is released, thus realizing the separation of the inner cover 7 from the bottle body 6.

[0037] In the embodiments provided by this utility model, the outer shell 1 and the bottle body 6 are connected by a threaded fastener 11. The threaded fastener 11 includes an internal thread 111 formed on the inner wall of the inner cover 7 and an external thread 112 provided on the extension head 61. The internal thread 111 and the external thread 112 are threadedly connected. The threaded connection method has good sealing performance and a firm connection, which can effectively prevent lip gloss leakage, while also making it convenient for users to open and close.

[0038] In the embodiments provided by this utility model, the stirring piston 5 is provided with a plurality of stirring through holes 51. The stirring through holes 51 increase the fluidity of the material during stirring, promote the exchange and mixing of the upper and lower layers of material, avoid local sedimentation, and also facilitate the full contact between the brush head 31 and the material in the bottle 6.

[0039] In the embodiments provided by this utility model, the brush head 31 and the reinforcing rib 10 are interference-fitted. That is, when the brush head 31 contacts the stirring piston 5, the brush head 31 and the reinforcing rib 10 are interference-fitted, which can completely eliminate the phenomenon of dry running and is suitable for stirring scenarios of high viscosity materials.
