Description

Technical Field

[0001] This utility model relates to a cosmetic structure, and more particularly to a cosmetic bottle with a stirring structure. Background Technology

[0002] Currently, makeup has become an indispensable beauty practice for women. Makeup is not only about paying attention to one's appearance but also a form of respect for others. Makeup products are also rapidly evolving. Traditional single-component cosmetic products are being improved based on customer needs. A new type of cosmetic ingredient has emerged on the market, characterized by being composed of two or more colors in varying proportions. Because these ingredients cannot fully blend, consumers may find it difficult to simultaneously enjoy the optimal effects of all the ingredients during use.

[0003] Currently, some packaging container designs on the market attempt to address the aforementioned problems by introducing mechanical structures such as steel balls, springs, or large spiral blades to enhance mixing. While these solutions can improve the issues of material settling and uneven mixing to some extent, they also increase production costs and operational complexity. Moreover, due to the non-smooth flow characteristics of the material, some of the material adheres to the surface of the mechanism. The complex internal structure not only occupies storage space but also causes a significant amount of residual material waste, greatly reducing the actual usable capacity for consumers, damaging the user experience, and potentially affecting brand image and repeat purchase intentions. Summary of the Invention

[0004] This utility model provides a cosmetic bottle with a stirring structure that is simple in structure, easy to operate, has a good stirring effect, can fully mix the product, and has a large material space inside the bottle; it solves the technical problems of existing cosmetic bottles where mixing of multiple materials is inconvenient or the stirring structure is too complicated.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: A cosmetic bottle with a stirring structure includes a bottle body and a bottle cap that cooperate with each other. A brush head structure is installed on the bottle cap. The brush head structure includes a brush head rod and a brush head fixing seat. The brush head fixing seat is fixed to the bottle cap. The brush head rod extends into the bottle body. A material filling cavity is provided in the bottle body. A stirring element is installed in the material filling cavity. The stirring element is detachably connected to the brush head rod. The stirring element moves axially with the brush head rod. When the user operates the brush head rod to remove the brush head rod from the bottle body, it drives the stirring element to move up and down. The up and down movement of the stirring element drives the various materials in the material filling cavity to mix thoroughly. When the brush head rod extends out of the bottle body, the stirring element is left in the bottle body because it is detachably connected to the brush head rod, which does not affect the use of the brush head. The stirring element is very small in size and does not affect the filling degree of the material in the material filling cavity. It does not occupy too much space, but ensures the stirring effect. Moreover, the stirring can be achieved by moving with the brush head rod, which is efficient and easy to operate.

[0006] Preferably, a guide structure is provided between the stirring element and the inner wall of the bottle. The guide structure allows the stirring element to move more smoothly up and down within the bottle.

[0007] Preferably, the guide structure consists of mutually cooperating protrusions and grooves, which are respectively disposed on the surfaces of the stirring component and the bottle body that come into contact with each other. The cooperation structure of the protrusions and grooves is simple: the protrusions are designed on the stirring component, and the grooves are designed on the inner wall surface of the bottle body, and vice versa.

[0008] Preferably, at least two protrusions are evenly distributed on the inner wall of the bottle, and the protrusions are arranged axially along the inner wall of the bottle. The protrusions are arranged vertically, and the stirring element moves axially, moving axially along with the brush head rod.

[0009] Preferably, the guiding structure includes protrusions evenly distributed on the outer circumferential surface of the stirring element, and the inner wall of the bottle body is provided with axially arranged spiral grooves. The spiral grooves are spiraled upwards, allowing the stirring element to rotate spirally while moving axially, thereby improving the stirring effect.

[0010] Preferably, the stirring component includes a stirring body and a stirring base. The stirring body is detachably connected to the brush head rod, and the outer circumferential surface of the stirring base is provided with a guide structure that cooperates with the bottle body.

[0011] Preferably, the mixing body is a flat plate, and the mixing seat is a ring formed on the outer circumference of the mixing body. Holes are formed in the flat plate, and a connecting hole is located at the center of the plate. The inner wall of the connecting hole is an outwardly protruding arc surface, and the brush head rod has a groove surface that mates with the arc surface. The hole design promotes thorough mixing of the materials, and the flat mixing body is small in size and low in cost. The arc surface of the connecting hole facilitates rotation between the mixing body and the brush head rod after they are engaged. The arc surface reduces friction, allowing for freer relative rotation. When the brush head rod rotates with the bottle cap, the mixing component remains stationary; only when the brush head rod is pulled outward will it cause the mixing component to move up and down, thus achieving mixing.

[0012] Preferably, the mixing body is an impeller with a central seat at its center. One end of the blades is fixed to the central seat, and the other end is fixed to an annular mixing base. A connecting hole is provided on the central seat, and the inner wall of the connecting hole is an outwardly convex arc surface. The brush head rod has a groove surface that mates with the arc surface. The impeller structure improves the mixing effect.

[0013] Preferably, the lower side of the inner wall of the bottle is provided with a lower stop step surface, and the bottle is fitted with a shoulder sleeve. The inner diameter of the stop step surface is smaller than the outer diameter of the agitator, and the inner diameter of the shoulder sleeve is smaller than the outer diameter of the agitator. The height of the agitator is 1 / 5 to 1 / 15 of the height of the bottle. The axial displacement stroke of the agitator is determined by the shoulder sleeve and the stop step surface, resulting in a simple structure. The agitator has a small volume, reducing the space occupied by the material.

[0014] Preferably, the bottle body and shoulder sleeve are connected using at least one method: a full-circle snap-fit ​​connection, a sealing ring connection, or ultrasonic welding. This ensures the sealing effect of the material, enhances the airtightness of the entire system, and guarantees product quality.

[0015] Therefore, the cosmetic bottle with a stirring structure of this invention has the following advantages: By designing a stirring element that moves up and down inside the bottle, and allowing the stirring element to move along with the brush head rod, stirring is achieved during the brush head rod's withdrawal process, eliminating the need for separate stirring, making operation simple and convenient. At the same time, the stirring unit is small in size, does not occupy excessive storage space, increases the actual usable capacity for consumers, and enhances the user experience and repeat purchase intention.

[0024] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] Example 1:

[0026] like Figure 1 and 2 As shown, a cosmetic bottle with a stirring structure includes a bottle body 1 and a cap 2 that fit together. A brush head structure is installed inside the cap 2. The brush head structure includes a brush head fixing seat 3 and a brush head rod 4, with a brush head 5 installed at the end of the brush head rod 4. The brush head fixing seat 3 has evenly distributed support ribs formed on its exterior. The support ribs are interference-fitted with the cap 2, thereby fixing the brush head structure to the cap 2. A shoulder sleeve 6 is installed at the junction of the bottle body 1 and the cap 2. The upper part of the shoulder sleeve 6 is connected to the cap 2, and the lower part of the shoulder sleeve 6 is connected to the bottle body 1. A sealing ring 7 is installed between the shoulder sleeve 6 and the bottle body 1. The shoulder sleeve 6 has threads, and the cap 2 is threadedly connected to the shoulder sleeve 6.

[0027] A grooved surface 8 is formed on the lower side of the brush head rod 4 near the brush head. The brush head rod 4 is made of plastic. Two symmetrical protrusions 9 are evenly distributed on the inner wall of the bottle body 1, but it is not limited to two; there can be multiple protrusions 9. A stop step surface 10 is formed on the lower part of the inner wall of the bottle body 1. A material filling cavity is formed inside the bottle body 1, and an agitator 11 is installed in the material filling cavity. The lower end face of the agitator 11 abuts against the stop step surface 10. The protrusions 9 extend from the stop step surface 10 to below the shoulder sleeve 6. The movement stroke of the agitator 11 is the distance between the stop step surface 10 and the lower end face of the shoulder sleeve 6 (e.g., ...). Figure 5 (As shown).

[0028] like Figure 3 and 4As shown, the stirring component 11 includes a stirring body 12 and a stirring seat 13. The stirring body 12 is a circular flat plate with holes 14 and a connecting hole 15 at its center. The inner wall of the connecting hole 15 is an outwardly protruding arc surface 16. The brush head rod 4 is inserted through the connecting hole and elastically engaged within the connecting hole 15 of the stirring component. The groove surface 17 on the brush head rod 4 engages with the protruding arc surface 16 of the connecting hole, allowing the stirring component 11 and the brush head rod 4 to rotate relative to each other. A ring-shaped body perpendicular to the stirring body is formed on the outer circumferential surface of the stirring body, serving as the stirring seat 13. Two grooves 18 are correspondingly provided on the outer circumferential surface of the stirring seat 13. The number and position of the grooves 18 on the stirring seat correspond to the number and position of the protrusions 9 on the inner wall of the bottle. The up-and-down movement of the stirring seat 13 is guided by the engagement of the grooves 18 and the protrusions 9. Of course, it is also possible for the protrusions to be designed on the stirring seat and the grooves to be designed on the inner wall of the bottle.

[0029] In use, the brush head rod is spring-loaded into the connecting hole. The protruding arc surface of the connecting hole engages with the recessed groove on the brush head rod, allowing the brush head rod and the mixing component to rotate relative to each other. Twisting the bottle cap rotates the brush head rod. When the cap is unscrewed and the brush head rod is removed from the bottle, it causes the mixing component to move upwards. The groove on the outer circumference of the mixing component and the protrusion on the inner wall of the bottle smoothly propel the mixing component upwards. Simultaneously, the perforated design of the mixing body ensures thorough mixing of the material within the filling cavity. When the brush head rod leaves the bottle, the shoulder sleeve retains the mixing component inside. Reinserting the brush head rod will re-engage it with the mixing component. The height of the mixing component is 1 / 6 of the bottle height. Its small size does not affect material filling.

[0030] Example 2:

[0031] like Figure 6 As shown, unlike Embodiment 1, the stirring component includes a stirring body 12 and a stirring seat 13. The stirring body is a petal-shaped flat plate with holes. The material channel between the recess of the petal-shaped stirring body and the inner wall can more evenly and effortlessly stir the material.

[0032] Example 3:

[0033] like Figure 7 As shown, unlike Embodiment 1, the stirring component is impeller-shaped, with a central seat 20 at the center of the impeller. One end of the blade 21 is fixed to the central seat 20, and the other end of the blade 21 is fixed to the annular stirring base 13. A connecting hole 15 is provided on the central seat 20, and the inner wall of the connecting hole 15 is an outwardly protruding arc surface 16. The brush head rod 4 is provided with a groove surface 17 that mates with the arc surface. The outer circumferential surface of the stirring base 13 is formed with protrusions 9. And the inner wall of the bottle is formed with grooves 18.

[0034] Example 4:

[0035] like Figure 8 As shown, unlike Example 3, a spiral groove 30 is formed on the inner wall of the bottle, and the stirring element 11 is in the shape of an impeller. The stirring element rises spirally along the spiral groove, which improves the stirring effect of the blade.
