[0032] like Figures 1-8 As shown, embodiments of this application provide a coating container and a coating packaging shell. The coating container is a component used to contain coatings in various forms, such as liquids, powders, pastes, or ointments. The coating container effectively isolates external contaminants to protect the hygiene of the coating, while providing stable structural support to ensure container stability, thus facilitating easy access and use of the product by the user. In the embodiments of this application, the coatings mentioned broadly cover two categories: cosmetics and skincare products. The coating container is detachably installed inside the coating packaging shell. After the coating inside is used up, the old coating container can be easily removed and replaced with a new one, allowing the packaging shell to be reused, which is beneficial for cost savings and environmental protection.

[0033] Examples of embodiments in this application, such as Figure 1-4 As shown, the coating container includes a cap 1 and a base 2. The cap 1 is used to open and close onto the base 2. The cap 1 is used to close or open the container, protecting the coating inside from external contamination. The base 2, as the main body of the container, is used to directly support the coating.

[0034] The chassis 2 includes a first side panel 21, on which a plurality of connecting grooves 24 are evenly distributed; a plurality of notched grooves 25 are evenly provided on the bottom edge of the chassis 2, and the connecting grooves 24 and notched grooves 25 are arranged alternately and staggered; the connecting grooves 24 and notched grooves 25 are used to fit and nest with the packaging shell of the container.

[0035] The chassis 2, as the main body of the container, includes a first side panel 21. Multiple connecting grooves 24 are evenly distributed on the outer wall of the first side panel 21, and multiple notched grooves 25 are evenly distributed along the bottom edge of the outer wall. Through the alternating staggered arrangement of the connecting grooves 24 and the notched grooves 25, a nested snap-fit ​​connection with the packaging shell is achieved, effectively preventing the container from loosening or falling off during use. Compared with traditional threaded or interference fit connections, the snap-fit ​​method in this embodiment is simpler and faster. When the user needs to replace or install the container, they only need to align the new container with the bottom shell of the packaging shell and press it down to complete the replacement.

[0036] In the embodiments of this application, such as Figure 1 and 2 As shown, the chassis 2 has a quadrilateral structure. The connecting groove 24 is located in the middle of each outer side wall of the chassis 2, and the notch groove 25 is located at the four apex corners of the quadrilateral structure. The notch groove 25 is used to abut against the inner bottom of the bottom shell of the packaging shell to achieve a stable fit between the chassis 2 and the inner bottom, avoiding the introduction of a third component, thereby achieving stable fixation between the chassis 2 and the bottom shell.

[0037] In another possible implementation, the chassis 2 is circular, and a plurality of connecting grooves 24 are evenly distributed circumferentially on the outer side wall of the first side wall 21, and notch grooves 25 are evenly distributed circumferentially on the bottom edge of the outer side wall, with the connecting grooves 24 and notch grooves 25 arranged alternately and staggered.

[0038] Furthermore, the connecting groove 24 is located near the bottom edge of the outer wall. This design allows the connecting groove 24 and the notch 25 to form a stepped contact surface with the bottom shell of the packaging shell, increasing the contact area between the chassis 2 and the bottom shell of the packaging shell, preventing plastic deformation caused by stress concentration during assembly, and providing more stable support.

[0039] Furthermore, a hinge seat 26 is provided on the outer side wall of the chassis 2 for hinged connection with the hinge portion 12 of the cover 1. In this embodiment, the hinge seat 26 is integrally formed with the chassis 2. The cover 1 is provided with a hinge portion 12 at the position corresponding to the hinge seat 26. The hinge portion 12 and the hinge seat 26 are adapted to each other and assembled by columnar structures such as pins to realize the rotational connection between the cover 1 and the chassis 2.

[0040] Furthermore, the inner wall of the first side panel 21 is provided with multiple snap-fit ​​slots 27, which are used to engage with the closing protrusions 13 on the cap 1. The cap 1 has an annular flange 11 on the side facing the chassis 2. On the outer wall of the annular flange 11, corresponding to the position of each snap-fit ​​slot 27, a closing protrusion 13 is provided to engage with the snap-fit ​​slot 27. This snap-fit ​​connection method greatly enhances the overall sealing and stability of the container. The snap-fit ​​structure, where each snap-fit ​​slot 27 tightly engages with the corresponding closing protrusion 13, provides sufficient locking force, ensuring that the cap 1 remains stable when opened or closed, preventing leakage or damage due to accidental loosening, and improving the user experience.

[0041] In one possible implementation, the position of one of the latching slots 27 is symmetrical about the center of the chassis 2 with respect to the position of the hinge seat 26, so that the entire chassis 2 can maintain a more uniform distribution when subjected to force, thereby effectively improving the overall stability and durability of the structure.

[0042] Furthermore, chassis 2 is made of polyethylene terephthalate (PET). PET material possesses excellent physical and chemical properties, providing chassis 2 with high strength, high toughness, and good corrosion resistance. This material not only effectively resists external impacts and abrasion, extending the container's lifespan, but also maintains stable performance under various environmental conditions, ensuring the safe storage of items inside the container. Compared to traditional metal or plastic materials, PET chassis 2 is lighter and more portable, recyclable, and reduces transportation costs and environmental burden.

[0043] Furthermore, the chassis 2 includes a second side panel 22, the outer diameter of which is smaller than the outer diameter of the first side panel 21, and the bottom of the second side panel 22 protrudes beyond the bottom of the first side panel 21.

[0044] Specifically, the second side enclosure 22 is arranged parallel to the inner side of the first side enclosure 21. The second side enclosure 22 and the bottom surface of the chassis 2 form a receiving cavity 121 for storing coating materials. The shape and height of the second side enclosure 22 are designed according to the shape and capacity requirements of the coating materials. Multiple connecting grooves 24 are evenly distributed on the outer side wall of the first side enclosure 21, and multiple notch grooves 25 are evenly provided on the bottom edge of the outer side wall. Based on the alternating staggered arrangement of the connecting grooves 24 and notch grooves 25, the bottom of the second side enclosure 22 protrudes from the first side enclosure 21, providing an additional support point for the chassis 2, and making it easier for the notch grooves 25 to abut against the inner bottom of the bottom shell, thus achieving stable fixation between the chassis 2 and the bottom shell.

[0045] Furthermore, a sealing ring 3 is provided between the first side panel 21 and the second side panel 22. The sealing ring 3 serves to enhance the sealing effect. The sealing ring 3 has a ring structure and a certain degree of elasticity, so as to provide better sealing pressure when the cap 1 is pressed tightly.

[0046] Furthermore, such as Figure 4 and 5 As shown, a sealing ring 4 is provided between the first side panel 21 and the sealing ring 3. The inner wall of the sealing ring 4 has an annular groove 45. The sealing ring 3 has a first protruding section 31 on the side facing the sealing ring 4. The annular groove 45 and the first protruding section 31 engage and lock together. The shape, size, and position of the first protruding section 31 match the annular groove 45. When the sealing ring 3 contacts the sealing ring 4 and is subjected to a certain pressure, the first protruding section 31 can smoothly embed into the annular groove 45, forming a tight sealing structure. The sealing ring 4 reduces the gap between the chassis 2 and the sealing ring 3, ensuring an effective sealing barrier is formed when the cover is closed, effectively preventing the penetration of fluids or gases. The tight engagement of the sealing ring 4 with the first protruding section 31 through the annular groove 45 further enhances the tightness of the entire sealing structure. This locking method ensures that the sealing ring 3 and the sealing ring 4 maintain stable sealing performance during long-term use, maintaining a good sealing effect even under pressure changes or vibration conditions.

[0047] In one possible implementation, two equally spaced annular grooves 45 are designed on the inner wall of the sealing ring 4. The sealing ring 3 has two first protruding sections 31 corresponding to the annular grooves 45 on the side facing the sealing ring 4. This double-annular-groove sealing structure further enhances the sealing and connection effect, making it particularly suitable for applications requiring high pressure or temperature fluctuations.

[0048] In another possible implementation, the inner wall of the sealing ring 4 is provided with a plurality of annular grooves 45, which are multi-level stepped structures, including at least two levels of grooves of different depths. The sealing ring 3, facing the sealing ring 4, has a plurality of first protrusions 31 corresponding to these annular grooves 45, each first protrusion 31 precisely matching its corresponding annular groove 45. This multi-level sealing structure not only improves the reliability and durability of the seal but also allows the sealing system to adapt to greater deformation and displacement.

[0049] Furthermore, such as Figure 6 and 7 As shown, the top of the outer wall of the sealing ring 4 is provided with an annular sealing lip 41, which is press-fitted with the cover 1. A relief groove 42 is provided below the annular sealing lip 41 to provide a space for the annular sealing lip 41 to be deformed by compression during the opening and closing of the cover 1.

[0050] In this embodiment, the inner wall of the annular protrusion 11 of the cover 1 is press-fitted with the annular sealing lip 41. Specifically, when the cover 1 is closed with the chassis, the annular sealing lip 41 deforms due to compression, thus tightly fitting against the outer wall of the annular protrusion 11. The press-fit between the annular protrusion 11 and the annular sealing lip 41 ensures that the sealing structure remains tight under dynamic conditions, guaranteeing the sealing effect between the cover 1 and the chassis 2. A relief groove 42 is provided below the annular sealing lip 41. The function of the relief groove 42 is to provide a space for the deformed annular sealing lip 41 during the opening and closing of the cover 1, avoiding permanent deformation or damage caused by excessive compression, further optimizing the sealing effect and extending the service life of the sealing ring.

[0051] The shape of the clearance groove 42 can be one of trapezoidal, V-shaped, U-shaped or arc-shaped grooves.

[0052] In this embodiment, the clearance groove 42 is an arc-shaped groove connected to the bottom of the annular sealing lip 41. In some possible implementations, the angle between the bottom of the clearance groove 42 and the groove wall connected to the annular sealing lip 41 is an obtuse angle to optimize deformation energy storage.

[0053] The sealing ring 4 is located between the sealing ring 3 and the first side panel 21 of the chassis 2, with its inner wall tightly fitting the outer wall of the sealing ring 3 to form a sealing interface. Simultaneously, the annular sealing lip 41 on the outer wall of the sealing ring 4 contacts the inner wall of the cover 1, achieving another layer of sealing. The sealing ring 3 serves as an intermediate component, connecting to the sealing ring 4 and also engaging with the first side panel 21 and the second side panel 22 of the chassis 2, together forming a complete sealing system.

[0054] In one possible implementation, the outer diameter of the annular sealing lip 41 is larger than the outer diameter of the outer wall of the sealing ring 4 body to ensure reliable sealing or positioning. The depth and width of the clearance groove can be optimized according to the deformation characteristics of the annular sealing lip 41 to ensure that deformation can be effectively accommodated without affecting the sealing effect.

[0055] Furthermore, the inner diameter of the sealing ring 4 is smaller than the outer diameter of the sealing ring 3. This design ensures that the sealing ring 4 fits tightly against the sealing ring 3, while providing a certain preload to enhance the sealing effect. This design allows the sealing ring 4 to undergo slight elastic deformation during installation, thereby tightly wrapping around the sealing ring 3 and forming an effective sealing interface.

[0056] Furthermore, such as Figure 5 As shown, the bottom inner wall of the sealing ring 4 is provided with a guide slope 43 that is inclined outward along the axial direction. The guide slope 43 is located on the bottom inner wall of the sealing ring 4 and contacts the outer wall of the sealing ring 3. During installation, the guide slope 43 guides the sealing ring 4 to smoothly fit into the sealing ring 3, improving assembly efficiency.

[0057] In one possible implementation, such as Figure 7 As shown, the outer wall of the sealing ring 4 is provided with at least one radially protruding sealing rib 44. The sealing rib 44 can be provided on the outer wall of the sealing ring 4 below the relief groove 42, for pressing contact with the first side panel 21 to achieve limiting and fixing of the sealing ring 4. The setting of the sealing rib 44 increases the contact area between the sealing ring 4 and the inner wall of the cover 1, improving the sealing effect. At the same time, the setting of the sealing rib 44 helps to disperse stress and prevent the sealing ring 4 from being locally damaged under pressure.

[0058] The sealing ring 4 can be made of thermoplastic rubber, nitrile rubber, or silicone. Thermoplastic rubber (TPE) is a material combining the elasticity of rubber and the processing properties of thermoplastics. It possesses good weather resistance, chemical resistance, and abrasion resistance, making it suitable for various temperature and pressure environments. It can be molded through thermoplastic processing methods such as injection molding and extrusion, facilitating large-scale production. Nitrile rubber (NBR) is a widely used synthetic rubber with excellent oil resistance, abrasion resistance, and chemical corrosion resistance. It is suitable for sealing applications involving contact with petroleum, greases, and various chemicals. It has moderate strength and elasticity and is easy to process and mold. Silicone is a high-performance synthetic rubber with excellent high-temperature resistance, low-temperature resistance, oxidation resistance, and ozone resistance. It also has good biocompatibility and electrical insulation. Silicone has good elasticity, is easily compressed and recovers, and is suitable for sealing applications requiring frequent compression and release.

[0059] In one possible implementation, a third sidewall 23 is provided between the first sidewall 21 and the second sidewall 22 of the chassis 2. A groove is formed between the third sidewall 23 and the second sidewall 22 to accommodate the first part of the sealing ring 3. A groove is also formed between the third sidewall 23 and the first sidewall 21 to accommodate the second part of the sealing ring 3, so that the sealing ring 3 can be supported on the third sidewall 23. When the cover 1 is closed onto the chassis 2, the cover 1 will come into contact with the sealing ring 3. Since the sealing ring 3 is firmly supported on the third sidewall 23, it can effectively prevent fluid or gas from leaking from the gap between the chassis 2 and the cover 1, thus ensuring both stability and sealing effect.

[0060] In one possible implementation, the sealing ring 3 has an inverted U-shaped cross-section. The inverted U-shaped sealing ring 3 is snapped onto the third sidewall 23, and a filler 33 is provided between the inverted U-shaped structure and the third sidewall 23 to reduce the gap between the sealing ring 3 and the third sidewall 23.

[0061] In one possible implementation, the filler 33 can be a soft rubber layer disposed within the U-shaped groove. The filler 33 is press-fitted with the third sidewall 23, specifically with an upper and lower press-fit. The inverted U-shaped sealing ring can better adapt to the shape of the third sidewall 23, and together with the press-fit of the filler, it can effectively reduce gaps, thereby improving sealing performance. The design of the filler 33 also ensures the stable position of the sealing ring 3 within the chassis 2, preventing displacement even during transportation or use. Furthermore, the soft rubber filler can absorb and disperse external forces, reducing wear between the sealing ring 3 and the third sidewall 23, and extending the service life of the container.

[0062] This application also provides a coating packaging shell, including an outer shell assembly and a coating container. The outer shell assembly includes a bottom shell and an outer cover, and the coating container is detachably connected to the bottom shell. The base 2 of the coating container is detachably connected to the bottom shell through a connecting groove 24 provided on its first side 21 and a notch 25 provided on its bottom edge.

[0063] The outer cover is designed to be opened and closed to fit over the bottom shell. In some possible implementations, the outer cover and the bottom shell are rotatably connected by a hinge structure.

[0064] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
