Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, specifically to a high-airtightness lip gloss bottle. Background Technology

[0002] With the development of cosmetic packaging technology, lip gloss products have seen significant improvements in both appearance design and functionality. However, in actual use, existing lip gloss bottles still have some issues that need to be addressed, especially regarding airtightness, a property that directly affects the product's shelf life and user experience.

[0003] A search revealed a patent document with publication number CN111728899B, which discloses a three-layer lip gloss and its preparation method, published on January 17, 2023. This invention achieves a multi-color makeup effect by layering three different colored lip glosses into the same bottle. While this solution is innovative in terms of product appearance and functionality, it does not optimize the airtight structure of the lip gloss bottle itself. Therefore, during long-term storage or frequent use, air may enter the bottle, causing the lip gloss to oxidize, deteriorate, or evaporate, thus affecting product quality and lifespan.

[0004] Furthermore, patent document CN112758864B discloses a rapid surface sealing device for lip gloss after filling, published on April 14, 2023. This utility model provides an automated sealing device for sealing the bottle mouth of lip gloss, achieving bottle mouth sealing through the cooperation of a rubber stopper and a connector. While this device has certain advantages in improving sealing efficiency, in practical applications, relying solely on the rubber stopper pressing method to ensure the overall airtightness of the bottle has certain limitations. Especially during transportation or in environments with large temperature variations, issues such as incomplete sealing and air leakage may occur, thus affecting the stability of the lip gloss.

[0005] In summary, current lip gloss bottles on the market have certain shortcomings in terms of airtightness, allowing air to easily enter and affecting product quality and shelf life. Therefore, proposing a highly airtight lip gloss bottle structure to improve sealing performance, extend product lifespan, and meet consumer demand for high-quality makeup products is particularly important. This invention aims to achieve a more efficient and stable airtight effect by optimizing the sealing structure between the bottle body and cap, overcoming the shortcomings of existing technologies.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides a high airtight lip gloss bottle, the structure of which is as follows: Figure 1 As shown, the device includes a bottle body 1 and a bottle cap 2. A sealing assembly is provided on the inner side of the bottle cap 2, consisting of an annular sealing ring 3 and an elastic clamping member 4. The annular sealing ring 3 is fixedly installed on the top of the inner wall of the bottle cap 2, and its outer diameter matches the inner wall diameter of the bottle body 1, allowing the annular sealing ring 3 to tightly fit the opening edge of the bottle body 1 when the bottle cap 2 is tightened. The elastic clamping member 4 is located below the annular sealing ring 3 and is fixed to the middle of the inner wall of the bottle cap 2 by a threaded connection. A set of arc-shaped pressure plates 5 are provided at the bottom end of the elastic clamping member 4. The inner surface of the arc-shaped pressure plates 5 fits against the opening edge of the bottle body 1, thereby forming a secondary seal at the opening of the bottle body 1 when the bottle cap 2 is tightened. This design improves the overall airtightness through a double-sealing structure.

[0027] An annular groove 6 is formed at the bottom of the inner wall of the bottle cap 2, and an airbag sealing ring 7 is embedded inside the annular groove 6. The outer surface of the airbag sealing ring 7 has multiple raised structures 8, designed to fit tightly against the inner wall of the bottle body 1 opening. When the bottle cap 2 is tightened, the airbag sealing ring 7 expands under pressure, further enhancing the sealing effect between the bottle body 1 and the bottle cap 2. This structure reduces the possibility of air entering through physical compression, while ensuring that the bottle cap 2 maintains good sealing performance even after repeated opening and closing.

[0028] The inner wall of the bottle opening 1 is provided with a spiral guide groove 9, which extends from the bottle opening into the interior of the bottle 1, and its end connects to the liquid storage chamber 10 inside the bottle 1. When the bottle cap 2 is screwed on, the air inside the bottle 1 is discharged along the spiral guide groove 9, thereby reducing the amount of residual air inside the bottle. This design effectively reduces the possibility of the lip gloss coming into contact with air through the guiding effect of the guide groove, avoiding product deterioration caused by oxidation. In addition, the design of the spiral guide groove 9 also prevents the lip gloss from overflowing from the bottle opening when inverted or tilted, further improving the convenience of use.

[0029] The bottle cap 2 has an exhaust valve 11 on its top, and a one-way valve core 12 is installed inside the exhaust valve 11. One end of the one-way valve core 12 is connected to the air inlet of the exhaust valve 11, and the other end is connected to the air outlet of the exhaust valve 11 via a spring 13. When the bottle cap 2 is tightened, excess gas inside the bottle is discharged through the one-way valve core 12, while outside air cannot enter the bottle through the one-way valve core 12. This one-way exhaust design ensures the pressure balance inside the bottle while preventing the intrusion of outside air, thereby further improving the product's preservation performance.

[0030] The outer side of the bottle cap 2 is provided with anti-slip texture 14, which is evenly distributed along the circumference of the bottle cap 2 and has a semi-circular cross-section. The design of the anti-slip texture 14 makes it easier for users to apply greater torque when tightening or loosening the bottle cap 2, thereby ensuring a tight fit between the bottle cap 2 and the bottle body 1. This structure not only improves the user experience but also effectively prevents the bottle cap 2 from loosening due to slipping.

[0031] The outer wall of the bottle 1 is provided with a transparent viewing window 15, which is made of polycarbonate and has a scratch-resistant surface. The transparent viewing window 15 allows users to easily see the remaining amount of lip gloss inside the bottle, while also preventing the bottle 1 from breaking due to external impact. This design ensures both practicality and safety, meeting users' dual needs for product appearance and function.

[0032] The bottom of the bottle body 1 is equipped with a detachable base 22 made of silicone. The base 22 has a snap-fit ​​structure 23 on its inner side, which matches the groove 24 on the bottom of the bottle body 1. The design of the base 22 not only enhances the stability of the bottle body 1 but also provides cushioning protection during transportation. Users can easily disassemble or install the base 22 for convenient cleaning or replacement.

[0033] The liquid storage chamber 10 of the bottle body 1 is equipped with a partition 16, which divides the liquid storage chamber 10 into two independent chambers. A through hole 17 is located at the center of the partition 16, and a filter screen 18 is installed inside the through hole 17. The design of the filter screen 18 effectively prevents particles in the lip gloss from entering the bottle opening, thus avoiding clogging. This structure not only improves the ease of use of the product but also extends its service life.

[0034] The inner side of the bottle cap 2 is provided with a temperature-sensing layer 19, which is made of a heat-sensitive material. The color of the temperature-sensing layer 19 changes with the ambient temperature. When the bottle 1 is in a high-temperature environment, the color of the temperature-sensing layer 19 turns red, reminding the user to pay attention to the storage conditions. This design intuitively reflects changes in ambient temperature through color change, thereby helping users better manage the storage status of the product.

[0035] A QR code 20 is located on the top of the bottle cap 2, and this QR code 20 is connected to a chip 21 inside the bottle body 1. The chip 21 records the lip gloss's production date, shelf life, and usage instructions. Users can obtain this information by scanning the QR code, thus improving the product's ease of use. This design combines modern information technology to provide users with a more intelligent user experience.

[0036] The above-described specific embodiments detail the structure and working principle of this utility model. Through the design of multiple sealing structures, including the annular sealing ring 3, the elastic clamping element 4, and the airbag sealing ring 7, the problem of oxidation and deterioration of lip gloss due to air ingress during long-term storage or frequent opening of existing lip gloss bottles is effectively solved. Simultaneously, the introduction of functional components such as the spiral guide groove 9, the exhaust valve 11, and the filter screen 18 further enhances the product's practicality and preservation performance.

[0037] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0038] First, after using the lip gloss, the user screws the cap 2 onto the opening of the bottle body 1. During this process, the annular sealing ring 3 fits tightly against the edge of the opening of the bottle body 1, forming the first layer of seal. Simultaneously, the arc-shaped pressure plate 5 at the bottom of the elastic clamping element 4 is subjected to the reaction force from the edge of the opening of the bottle body 1, resulting in inward elastic deformation, further pressing the edge of the opening of the bottle body 1 to form the second layer of seal. This double-seal design achieves a tight fit between the bottle body 1 and the cap 2 through mechanical pressure, effectively reducing the possibility of air entering.

[0039] Next, as the bottle cap 2 continues to tighten, the airbag sealing ring 7 is compressed by the inner wall of the bottle body 1 opening, causing its internal volume to decrease and expand. The raised structure 8 on the outer surface of the airbag sealing ring 7 forms multi-point contact with the inner wall of the bottle body 1 opening, further enhancing the sealing effect. This physical compression method not only improves the sealing performance between the bottle cap 2 and the bottle body 1, but also maintains a stable sealing state after repeated opening and closing, avoiding sealing failure due to long-term use.

[0040] Subsequently, as the cap 2 is tightened, the air inside the bottle 1 is gradually discharged along the spiral guide channel 9. The design of the spiral guide channel 9 guides the air during the discharge process, reducing the possibility of air retention. Simultaneously, the end of the spiral guide channel 9 connects to the liquid storage chamber 10, ensuring complete air discharge and thus reducing the amount of residual air inside the bottle. This design effectively slows down the oxidation process of the lip gloss by reducing the contact area between the lip gloss and air, ensuring product stability.

[0041] Meanwhile, the vent valve 11 on top of the bottle cap 2 begins to function. When the bottle cap 2 is tightened to a certain extent, excess gas inside the bottle is released through the one-way valve core 12. The one-way valve core 12 remains closed under the action of the spring 13, preventing outside air from entering the bottle through the vent valve 11. This one-way venting design not only balances the pressure inside the bottle but also prevents the intrusion of outside air, thereby further improving the product's preservation performance.

[0042] During user use, the anti-slip texture 14 on the outer side of the cap 2 provides additional friction. When the user applies torque, the anti-slip texture 14 effectively prevents slippage, ensuring a tight fit between the cap 2 and the bottle body 1. In addition, the transparent viewing window 15 on the outer wall of the bottle body 1 allows the user to easily see the remaining amount of lip gloss inside the bottle, preventing air from entering the bottle due to frequent opening of the cap 2.

[0043] The detachable base 22 at the bottom of the bottle 1 serves as a cushioning and protective element during transportation. Users can easily remove the base 22 to clean the groove 24 at the bottom of the bottle 1. Meanwhile, the partition 16 inside the liquid storage chamber 10 of the bottle 1 divides the lip gloss into two independent chambers, and the filter 18 effectively prevents particles in the lip gloss from entering the bottle opening, avoiding clogging.

[0044] Finally, the temperature-sensing layer 19 on the inside of the bottle cap 2 changes color according to the ambient temperature. When the bottle 1 is in a high-temperature environment, the temperature-sensing layer 19 turns red to remind the user to pay attention to storage conditions. In addition, users can scan the QR code 20 on the top of the bottle cap 2 to obtain the production date, shelf life, and usage instructions recorded in the chip 21, thereby better managing the product's lifecycle.

[0045] The above steps, combined with the specific structure shown in the accompanying drawings, elaborate in detail the operating principle and technical effect of this utility model in practical applications. Through multiple sealing structures, the synergistic effect of functional components, and intelligent design, this utility model effectively solves the problem of lip gloss oxidation and deterioration caused by air entering during long-term storage or frequent opening of existing lip gloss bottles, while improving the product's practicality and user experience.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
