Description

Technical Field

[0001] This utility model relates to the field of sealed packaging technology, and more specifically, to a sealed packaging can. Background Technology

[0002] In the food and health product packaging industry, different forms of contents, such as powder, solid, and liquid, have clear requirements for the sealing, hygiene, and ease of use of packaging containers. Most existing sealed packaging containers adopt a single lid and sealing ring structure design, which can achieve basic sealing, but generally suffers from problems such as easy contamination of the contents and easy moisture absorption and clumping of powdery items. Since most packaging containers do not have independent dispensing parts, users need to use a spoon to scoop out the contents. The external spoon can easily introduce impurities and cause secondary contamination. Furthermore, if the water vapor remaining after the spoon comes into direct contact with the powder inside the container, it will cause the powder to absorb moisture and clump, affecting the quality of the contents and the consumption experience.

[0003] Meanwhile, in some packaging cans with built-in spoons, the spoon is often placed directly inside the contents, failing to completely isolate the spoon from the contents and still posing a risk of contamination and moisture absorption. Furthermore, the existing lid connection structure of packaging cans often suffers from inconvenient opening and closing and unstable sealing performance. After long-term use, external air and moisture can easily enter the can due to displacement of the seals and loosening of the connections, further reducing the shelf life of the contents. In addition, the assembly of components in existing packaging cans often relies on complex connectors, making the production process cumbersome and unsuitable for mass production. Moreover, users are prone to problems such as component damage and abnormal noises during operation. Overall, the reliability and practicality of use need to be improved.

[0004] Therefore, there is an urgent need for a sealed packaging container that can completely separate the spoon from the contents, has stable sealing performance, is easy to open and close, and is easy to mass-produce, in order to solve the problems of insufficient pollution control, poor sealing reliability, and low ease of use in the existing technology, and meet the demand of food and health products for high-quality packaging. Utility Model Content

[0005] The present invention aims to provide a sealed packaging can to solve the problems of insufficient pollution control, poor sealing reliability and low ease of use in the prior art.

[0006] The embodiments of this utility model are implemented as follows: This utility model provides a sealed packaging can, which includes a can body; The top of the aforementioned tank is sealed with an upper cover, which has a through hole communicating with the aforementioned tank. An inner cover for sealing is hinged in the through hole. A spoon mounting hole is opened in the groove on the top surface of the inner cover, and a measuring spoon is embedded in the spoon mounting hole. A cover plate for sealing is hinged in the groove.

[0007] In use, first operate the aforementioned cover, apply force to open the cover, causing it to detach from the groove of the inner cover. At this time, the spoon mounting hole of the inner cover is open, allowing the measuring spoon to be taken out directly from the spoon mounting hole. After removing the measuring spoon, reattach the cover to the groove. Next, open the inner cover, apply force to separate the inner cover from the upper cover, opening the through hole of the upper cover, allowing the inside of the can to communicate with the outside. Then, holding the measuring spoon, scoop the contents of the can through the through hole of the upper cover. After use, first reset the inner cover and fasten it to the upper cover, then place the measuring spoon back into the spoon mounting hole of the inner cover, and finally close the cover, ensuring it is tightly fastened to the groove, thus completing the sealed storage of the packaging can.

[0008] The sealed packaging can disclosed in this embodiment features a groove and a spoon mounting hole on the inner lid, allowing the measuring spoon to be placed independently within the mounting hole. The engagement of the lid and the groove completely isolates the measuring spoon from the contents of the can. Simultaneously, the upper lid has a through hole for assembling the inner lid and for retrieving the contents. The inner lid and upper lid, as well as the lid and groove, are securely connected and sealed via a matching structure. All components work together to prevent external impurities from entering and to prevent contamination of the contents during retrieval. Furthermore, the independent placement of the measuring spoon, combined with the overall sealing structure, effectively prevents moisture from contacting the powdery contents and causing clumping. Therefore, this sealed packaging can offers the advantages of isolating the measuring spoon from the contents to prevent contamination, providing stable sealing performance, preventing moisture absorption, and offering high ease of use.

[0009] Optionally: the bottom end of the inner cover has a first mounting groove, the first mounting groove is embedded with a first flexible sealing ring, the first flexible sealing ring has a sealing ring around its circumference, the inner wall of the through hole of the upper cover has a sealing surface, and the sealing ring is tightly attached to the sealing surface.

[0010] This design allows the first mounting groove to stably limit the position of the first flexible sealing ring, preventing it from shifting during use. Simultaneously, the tight fit between the sealing ring and the sealing surface effectively enhances the sealing performance between the inner and upper covers, reducing the entry of external air and moisture into the can. This lowers the risk of food and health products becoming damp and clumping, ensuring the quality of the contents. Furthermore, this structure is simple and reliable, requiring no additional complex assembly processes, which facilitates mass production and practical application of the can.

[0011] Optionally: an annular groove is provided in the circumferential direction at the bottom end of the upper cover, and a second flexible sealing ring is embedded in the annular groove, and the opening end of the tank body tightly abuts against the second flexible sealing ring.

[0012] This design serves two purposes: firstly, the annular groove provides stable positioning for the second flexible sealing ring, preventing it from shifting or falling off during assembly and use of the packaging can, thus ensuring the stability of the sealing structure; secondly, the tight contact between the opening of the can and the second flexible sealing ring effectively blocks the gap between the top cover and the can, reducing the entry of external air, moisture, and impurities into the can, preventing powdery, solid, or liquid foods and health products inside from becoming damp, spoiled, or contaminated, thus ensuring the quality of the contents. Moreover, this structure is simple in design, requires no complex parts, and is easy to mass-produce and assemble, adapting to the actual application needs of packaging cans.

[0013] Optionally: the cover plate is provided with a first rotating shaft and a first fastening tooth, the groove is provided with the same number of first mounting holes and first fastening holes, the first rotating shaft of the cover plate is rotatably hinged to the first mounting hole of the groove, and the first fastening tooth of the cover plate is fastened to the first fastening hole of the groove.

[0014] With this configuration, the hinge structure between the first rotating shaft and the first mounting hole enables the cover to open and close stably and flexibly, making it convenient for users to open the cover to take out the measuring spoon or close the cover. In addition, the snapping engagement between the first snap tooth and the first snap hole ensures the connection stability of the cover when it is closed with the groove, preventing the measuring spoon from shifting or external impurities from entering due to accidental loosening of the cover.

[0015] Optionally, the cover plate has a support ring on the side near the groove, one end of the support ring is fixed to the side of the cover plate near the groove, and the other end of the support ring abuts against the opening of the spoon mounting hole.

[0016] This design effectively limits the position of the measuring spoon placed in the mounting hole, preventing it from shaking or shifting during handling and use of the packaging can. This prevents noise caused by spoon shaking or wear from friction with the hole wall. Simultaneously, it indirectly reduces the possibility of external impurities entering the can through the mounting hole, ensuring the stability of the measuring spoon during use and placement. Furthermore, the simple design of the support ring eliminates the need for additional complex parts, allowing for easy integration with the lid or assembly. This adapts to the overall structure of the packaging can and meets the needs of mass production, further enhancing the reliability and user experience of the packaging can.

[0017] Optionally: the inner cover is provided with a second pivot and a second snap tooth, the through hole is provided with the same number of second mounting holes and second snap holes, the second pivot of the inner cover is rotatably hinged to the second mounting hole of the through hole, and the second snap tooth of the inner cover is engaged with the second snap hole of the through hole.

[0018] This design, through the hinge structure of the second pivot and the second mounting hole, enables the inner cover to be stably and flexibly flipped open and closed relative to the upper cover, making it convenient for users to scoop the contents of the can with the measuring spoon after opening the inner cover. In addition, the engagement between the second snap tooth and the second snap hole ensures the tightness of the connection between the inner cover and the through hole when closed, preventing the inner cover from accidentally loosening and causing the can to lose its seal and allow outside air and moisture to enter, thereby ensuring the quality of the food and health products inside the can.

[0019] Optionally: the outer circumference of the upper cover is provided with a plurality of foldable connecting blocks, the inner side of the connecting blocks is provided with mounting teeth, the outer circumference of the mouth of the can is provided with a limiting ring, the second flexible sealing ring is located between the upper cover and the mouth of the can, and the mounting teeth on the connecting blocks can be tightly snapped onto the limiting ring of the can.

[0020] This design, through the cooperation of the foldable connecting block and the limiting ring, enables quick assembly and secure connection between the top cover and the can, while also facilitating easy disassembly and meeting the daily needs of users. The second flexible sealing ring fills the gap between the top cover and the can opening, and, in conjunction with the tight snap-fit ​​between the mounting teeth and the limiting ring, effectively enhances the sealing performance after the connection, reducing the intrusion of external air and moisture into the can and preventing the food and health products inside from becoming damp, spoiled, or contaminated. At the same time, this structure does not require complex locking parts, resulting in low production and assembly costs and facilitating mass production of packaging cans.

[0021] Optionally, a first opening is provided on the groove wall corresponding to the first snap tooth, and the first opening penetrates the top surface of the inner cover along the axial direction of the inner cover.

[0022] With this design, the first opening provides operating space for the engagement or disengagement of the first snap tooth and the first snap hole, allowing users to easily open the cover by applying force through the first opening, thus improving ease of use. The first opening structure prevents the groove wall from excessively wrapping around the first snap tooth, reducing frictional wear between the groove wall and the first snap tooth during engagement. It also facilitates manufacturing, eliminating the need for complex avoidance designs on the groove wall, and adapts to the overall structure of the inner cover. While ensuring the stability of the engagement between the cover and the inner cover, it further optimizes the user experience and production assembly efficiency.

[0023] Optionally, a second opening is provided on the wall of the through hole corresponding to the second buckle tooth, and the second opening penetrates the top surface of the upper cover along the axial direction of the upper cover.

[0024] With this design, the second opening provides operating space for the second snap tooth to engage or disengage with the wall of the through hole, thereby improving ease of use. It also prevents the hole wall from excessively enveloping the second snap tooth, reducing frictional wear and simplifying the manufacturing process of the upper cover. This design ensures the stability of the engagement between the inner cover and the upper cover while optimizing production efficiency and user experience.

[0025] Optionally, the number of the connecting blocks is three to six, and they are evenly distributed along the outer circumference of the upper cover.

[0026] This configuration, with three to six blocks, ensures connection strength while avoiding material waste and operational complexity caused by excessive quantity. It ensures the stability of the snap-fit ​​connection between the top cover and the can, and facilitates user operation by folding the connecting blocks. The evenly distributed structure allows the locking force of the connecting blocks on the can to be evenly transmitted along the circumference, preventing excessive local stress that could cause deformation of the can or top cover. In addition, the second flexible sealing ring further ensures the uniformity of the seal, reduces gaps caused by uneven stress, and effectively improves the overall sealing reliability and structural stability of the packaging can.

[0027] Optionally, both the first flexible sealing ring and the second flexible sealing ring are made of food-grade elastic material.

[0028] This design meets the safety requirements for contact materials in food and health product packaging, prevents the release of harmful substances from the sealing ring material that could contaminate the contents, ensures food safety for users, and aligns with the application scenarios of packaging cans. On the other hand, the elastic material ensures that the sealing ring can fully deform during the compression sealing process, tightly fitting the sealing surface or the top surface, improving the sealing effect between the inner cover and the upper cover, and between the upper cover and the can body, reducing the intrusion of air and moisture. At the same time, the elastic material has good durability, can withstand repeated opening and closing compressions without easily being damaged, and extends the service life of the packaging can.

[0029] Optionally, the meshing surfaces of the first and second teeth with the first and second holes are both arc-shaped surfaces.

[0030] This design reduces frictional resistance when the teeth and holes engage or disengage, making the opening and closing of the cover and inner cover, and the inner cover and upper cover smoother and easier. It also avoids wear on components caused by rigid friction and extends the service life of the engagement structure. The arc-shaped surface increases the contact area between the teeth and holes, improving the stability of the connection after engagement and preventing loosening due to vibration, handling, or other external forces. At the same time, the arc-shaped structure disperses stress concentration during engagement, preventing the teeth or holes from breaking due to excessive local stress and ensuring the reliability of the overall structure of the sealed packaging can.

[0031] In summary, the sealed packaging container disclosed in this utility model has the beneficial effects of isolating the measuring spoon from the contents to prevent contamination, ensuring stable sealing performance and preventing moisture, and providing high ease of use.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example See Figures 1-10 This embodiment proposes a sealed packaging can, including a can body 1; The top of the tank body 1 is sealed with an upper cover 2. The upper cover 2 has a through hole 3 that communicates with the tank body 1. An inner cover 4 for sealing is hinged in the through hole 3. A spoon mounting hole 6 is opened in the groove 5 on the top surface of the inner cover 4. A measuring spoon 7 is embedded in the spoon mounting hole 6. A cover plate 8 for sealing is hinged in the groove 5.

[0038] In use, first operate the cover 8, apply force to open the cover 8, so that the cover 8 is disengaged from the groove 5 of the inner cover 4. At this time, the spoon mounting hole 6 of the inner cover 4 is open, and the measuring spoon 7 can be taken out directly from the spoon mounting hole 6. After taking out the measuring spoon 7, put the cover 8 back onto the groove 5. Then open the inner cover 4, apply force to separate the inner cover 4 from the upper cover 2, and the through hole 3 of the upper cover 2 will open, and the inside of the can 1 will be connected to the outside through the through hole 3. Then hold the measuring spoon 7 and scoop the contents of the can 1 through the through hole 3 of the upper cover 2. After taking out the contents, first put the inner cover 4 back and fasten it to the upper cover 2, then put the measuring spoon 7 back into the spoon mounting hole 6 of the inner cover 4, and finally close the cover 8 so that the cover 8 is tightly fastened to the groove 5, thus completing the sealed storage of the packaging can.

[0039] The sealed packaging can disclosed in this embodiment features a groove 5 and a spoon mounting hole 6 on the inner lid 4, allowing a measuring spoon 7 to be independently placed within the spoon mounting hole 6. The engagement of the lid 8 with the groove 5 completely isolates the measuring spoon 7 from the contents of the can 1. Simultaneously, the upper lid 2 has a through hole 3 for assembling the inner lid 4 and for accessing the contents. The inner lid 4 and upper lid 2, as well as the lid 8 and groove 5, are securely connected and sealed through an adapter structure. All components work together to prevent external impurities from entering and to prevent contamination of the contents during use. Furthermore, the independent placement of the measuring spoon 7, combined with the overall sealing structure, effectively prevents moisture from contacting the powdery contents and causing clumping. Therefore, this sealed packaging can offers the advantages of isolating the measuring spoon 7 from the contents to prevent contamination, providing stable sealing performance, preventing moisture absorption, and offering high ease of use.

[0040] See Figures 1-10 The bottom end of the inner cover 4 has a first mounting groove 9, in which a first flexible sealing ring 10 is embedded. The first flexible sealing ring 10 has a sealing ring 11 around its circumference. The inner wall of the through hole 3 of the upper cover 2 has a sealing surface 12. The sealing ring 11 is tightly attached to the sealing surface 12. In this way, the first mounting groove 9 can stably limit the first flexible sealing ring 10, preventing it from shifting during the use of the packaging can. At the same time, the tight fit between the sealing ring 11 and the sealing surface 12 effectively enhances the sealing performance between the inner cover 4 and the upper cover 2, reducing the entry of external air and moisture into the packaging can, thereby reducing the risk of food and health products inside the can becoming damp and clumping, ensuring the quality of the contents. Moreover, this structure is simple and reliable, without adding complicated assembly processes, which is conducive to the mass production and practical application of the packaging can.

[0041] An annular groove 13 is formed on the bottom circumference of the upper cover 2. A second flexible sealing ring 14 is embedded in the groove 13. The open end of the can body 1 tightly abuts against the second flexible sealing ring 14. On the one hand, the annular groove 13 can stably limit the second flexible sealing ring 14, preventing it from shifting or falling off during the assembly and use of the packaging can, thus ensuring the stability of the sealing structure. On the other hand, the tight abutment between the open end of the can body 1 and the second flexible sealing ring 14 can effectively block the gap between the upper cover 2 and the can body 1, reducing the entry of external air, moisture and impurities into the can, preventing powdery, solid or liquid food and health products inside the can from becoming damp, deteriorating or contaminated, and ensuring the quality of the contents. Moreover, this structure is simple in design, requires no complex parts, is easy to mass-produce and assemble, and is suitable for the actual application needs of packaging cans.

[0042] See Figures 1-10The cover plate 8 is provided with a first rotating shaft 15 and a first fastening tooth 16. The groove 5 is provided with the same number of first mounting holes 17 and first fastening holes 18. The first rotating shaft 15 of the cover plate 8 is rotatably hinged to the first mounting hole 17 of the groove 5. The first fastening tooth 16 of the cover plate 8 is fastened to the first fastening hole 18 of the groove 5. By means of the hinge structure between the first rotating shaft 15 and the first mounting hole 17, the cover plate 8 can be opened and closed stably and flexibly, making it convenient for users to open the cover plate 8 to take out the measuring spoon 7 or close the cover plate 8. In addition, the fastening cooperation between the first fastening tooth 16 and the first fastening hole 18 ensures the connection stability of the cover plate 8 and the groove 5 when closed, and avoids the cover plate 8 from accidentally loosening, causing the measuring spoon 7 to shift or external impurities to enter.

[0043] The cover plate 8 has a support ring 19 on the side near the groove 5. One end of the support ring 19 is fixed to the side of the cover plate 8 near the groove 5, and the other end of the support ring 19 abuts against the opening of the spoon mounting hole 6. This effectively limits the position of the measuring spoon 7 placed in the spoon mounting hole 6, preventing the measuring spoon 7 from shaking or shifting in the spoon mounting hole 6 during the handling and use of the packaging can. This also prevents abnormal noise caused by the shaking of the spoon body or wear caused by friction with the hole wall. At the same time, it can indirectly reduce the possibility of external impurities entering the can through the opening of the spoon mounting hole 6, while ensuring the stability of the measuring spoon 7 when it is taken out and placed. Moreover, the support ring 19 has a simple structural design, requires no additional complex accessories, and is easy to integrally mold or assemble with the cover plate 8. It is suitable for the overall structure of the packaging can and the needs of mass production, further improving the reliability of the packaging can and the user experience.

[0044] See Figures 1-10 The inner cover 4 is provided with a second rotating shaft 20 and a second fastening tooth 21. The through hole 3 is provided with the same number of second mounting holes 22 and second fastening holes 23. The second rotating shaft 20 of the inner cover 4 is rotatably hinged to the second mounting hole 22 of the through hole 3. The second fastening tooth 21 of the inner cover 4 is fastened to the second fastening hole 23 of the through hole 3. By means of the hinge structure between the second rotating shaft 20 and the second mounting hole 22, the inner cover 4 can be stably and flexibly flipped open and closed relative to the upper cover 2, making it convenient for users to open the inner cover 4 and use the measuring spoon 7 to scoop out the contents of the can. In addition, the fastening cooperation between the second fastening tooth 21 and the second fastening hole 23 can ensure the tightness of the connection between the inner cover 4 and the through hole 3 when closed, avoiding the inner cover 4 from accidentally loosening and causing the can to fail to seal and allow outside air and moisture to enter, thereby ensuring the quality of the food and health products in the can.

[0045] The outer circumference of the upper cover 2 is provided with multiple foldable connecting blocks 24, and the inner side of the connecting blocks 24 is provided with mounting teeth 25. The outer circumference of the opening of the can body 1 is provided with a limiting ring 26. The second flexible sealing ring 14 is located between the upper cover 2 and the opening of the can body. The mounting teeth 25 on the connecting blocks 24 can be tightly snapped onto the limiting ring 26 of the can body 1. With the snapping cooperation between the foldable connecting blocks 24 and the limiting ring 26, the upper cover 2 and the can body 1 can be quickly assembled and securely connected. The disassembly operation is convenient and meets the daily use needs of users. The second flexible sealing ring 14 can fill the gap between the upper cover 2 and the opening of the can body 1. With the tight snapping of the mounting teeth 25 and the limiting ring 26, the sealing performance after the two are connected is effectively enhanced, reducing the intrusion of external air and moisture into the can and preventing the food and health products in the can from becoming damp, deteriorating or contaminated. At the same time, this structure does not require complex locking parts, resulting in low production and assembly costs and facilitating the mass production of packaging cans.

[0046] See Figures 1-10 A first opening 27 is provided on the groove wall of the groove 5 corresponding to the first snap tooth 16. The first opening 27 penetrates the top surface of the inner cover 4 along the axial direction of the inner cover 4. The first opening 27 provides operating space for the first snap tooth 16 and the first snap hole 18 to engage or disengage, making it convenient for users to apply force with the first opening 27 to easily open the cover 8, thus improving ease of use. The structure of the first opening 27 can prevent the groove wall of the groove 5 from over-wrapping the first snap tooth 16, reducing frictional wear between the groove wall of the groove 5 and the first snap tooth 16 during the engagement process. At the same time, it is easy to process and manufacture, without the need for complex avoidance design of the groove wall of the groove 5. It is compatible with the overall structure of the inner cover 4, and further optimizes the user operation experience and production assembly efficiency while ensuring the engagement stability of the cover 8 and the inner cover 4.

[0047] The second opening 28 is provided on the wall of the through hole 3 corresponding to the second buckle 21. The second opening 28 penetrates the top surface of the upper cover 2 along the axial direction of the upper cover 2. The second opening 28 provides operating space for the second buckle 21 to engage or disengage with the wall of the through hole 3, thereby improving ease of use. It also avoids the hole wall from excessively wrapping the second buckle 21, reducing frictional wear and simplifying the manufacturing process of the upper cover 2. While ensuring the stability of the engagement between the inner cover 4 and the upper cover 2, it optimizes production efficiency and user experience.

[0048] See Figures 1-10The number of connecting blocks 24 is three to six, and they are evenly distributed along the outer circle of the upper cover 2. The number of three to six can ensure the connection strength while avoiding material waste and complicated operation caused by too many blocks. It can ensure the stability of the snap-fit ​​connection between the upper cover 2 and the can 1, and make it easy for users to fold the connecting blocks 24 to complete the opening and closing operation. The evenly distributed structure can make the locking force of the connecting blocks 24 on the can 1 be evenly transmitted along the circumference, avoiding excessive local force that could cause deformation of the can 1 or the upper cover 2. At the same time, the second flexible sealing ring 14 can further ensure the uniformity of the seal, reduce the sealing gaps caused by uneven force, and effectively improve the overall sealing reliability and structural stability of the packaging can.

[0049] The first flexible sealing ring 10 and the second flexible sealing ring 14 are both made of food-grade elastic material. This meets the safety requirements of food and health product packaging for contact materials, prevents the sealing ring material from releasing harmful substances that contaminate the contents, ensures the safety of users, and meets the application requirements of packaging cans. On the other hand, the elastic material can ensure that the sealing ring can fully deform during the compression sealing process, tightly fit the sealing surface 12 or the top surface, improve the sealing effect between the inner cover 4 and the upper cover 2, and between the upper cover 2 and the can body 1, reduce the intrusion of air and moisture. At the same time, the elastic material has good durability and can withstand multiple opening and closing compressions without being easily damaged, extending the service life of the packaging can.

[0050] The engagement surfaces of the first snap tooth 16 and the second snap tooth 21 with the first snap hole 18 and the second snap hole 23 are both arc-shaped. The arc-shaped engagement surfaces can reduce the frictional resistance when the snap tooth and the snap hole are engaged or disengaged, making the opening and closing operations of the cover 8 and the inner cover 4, and the inner cover 4 and the upper cover 2 smoother and less strenuous, avoiding wear of parts caused by rigid friction and extending the service life of the engagement structure. The arc-shaped surface can increase the contact area between the snap tooth and the snap hole, improve the connection stability after engagement, and prevent loosening due to external forces such as vibration and handling after engagement. At the same time, the arc-shaped structure can disperse the stress concentration during engagement, preventing the snap tooth or snap hole from breaking due to excessive local stress, and ensuring the reliability of the overall structure of the sealed packaging can.

[0051] See Figures 1-10 In this embodiment, the inner diameter of the support ring 19 is matched with the outer diameter of the measuring spoon 7. This allows the support ring 19 to tightly wrap around the outside of the measuring spoon 7, maximizing the limiting effect on the measuring spoon 7. This effectively prevents the measuring spoon 7 from shifting or colliding with the hole wall of the spoon mounting hole 6 during the handling, shaking, or opening and closing of the packaging can, and completely eliminates abnormal noise and wear caused by the shaking of the spoon body.

[0052] See Figures 1-10In this embodiment, the sealed packaging can is used for packaging powdered, solid, or liquid food and health products. This clarifies the applicable scenarios of the packaging can, and allows the structural design to accurately match the core requirements of food and health products for packaging sealing and hygiene, avoiding powder clumping, solid items getting damp, and liquid items leaking. At the same time, it prevents the measuring spoon 7 from causing secondary pollution, ensuring the quality of the contents and food safety.

[0053] See Figures 1-10 In this embodiment, the measuring spoon 7 has a capacity scale on its body (not shown in the figure), which allows users to intuitively read the amount scooped, accurately control the dosage of food and health products, meet the quantitative consumption needs, and avoid affecting the consumption effect or causing waste due to the deviation in dosage estimation.

[0054] See Figures 1-10 In this embodiment, the sealing surface 12 of the upper cover 2 is a smooth plane, and the sealing ring 11 of the first flexible sealing ring 10 fits tightly with the smooth plane. The smooth plane can reduce the contact resistance and gap when the sealing ring 11 fits, so that the sealing ring 11 can cover the sealing surface 12 more evenly, avoid local sealing failure due to the roughness of the sealing surface 12, significantly improve the sealing reliability between the inner cover 4 and the upper cover 2, and effectively block the intrusion of external air and water vapor into the tank.

[0055] See Figures 1-10 In this embodiment, it mainly consists of a cover plate 8, a measuring spoon 7, an inner cover 4, a first flexible sealing ring 10, a second flexible sealing ring 14, an upper cover body 2, and a can body 1. This packaging can can be used for packaging food and health products in powder, solid, and liquid forms. Through structural innovation, the packaging can has a built-in measuring spoon 7, which is independently installed on the inner cover 4, to achieve complete separation between the spoon and the contents of the packaging. This avoids secondary contamination of the food inside the packaging by the spoon during user use, as well as the clumping and dampness of the powdered food inside the spoon caused by residual water vapor on the spoon body.

[0056] See Figures 1-10 In this embodiment, when the inner cover 4 and the upper cover 2 are locked, the sealing ring 11 provided by the first flexible sealing ring 10 squeezes the sealing surface 12 provided by the upper cover 2 to achieve relative sealing; the upper cover 2 and the tank 1 are locked by the mounting teeth 25 on the connecting block 24 and the limiting ring 26, and the first flexible sealing ring 10 is squeezed to achieve relative sealing.

[0057] See Figures 1-10 The specific operating principle of the sealed packaging can in this embodiment is as follows: When using this sealed packaging container, first open the cover 8, and apply force with the first opening 27 on the groove wall of the groove 5 on the top surface of the inner cover 4 to make the first snap tooth 16 of the cover 8 disengage from the first snap hole 18 of the groove 5. Then, flip the cover 8 around the hinge structure formed by the first pivot 15 and the first mounting hole 17 around the cover 8 and the groove 5. At this time, the spoon mounting hole 6 of the inner cover 4 is open, and the measuring spoon 7 can be taken out directly from the spoon mounting hole 6. The cover 8 is provided with a support ring 19 on the side near the groove 5. When flipping the cover 8, the support ring 19 moves synchronously with the cover 8 and no longer presses against the opening of the spoon mounting hole 6. After removing the measuring spoon 7, first reset the cover plate 8 so that the first snap tooth 16 re-engages into the first snap hole 18, and the support ring 19 again presses against the opening of the spoon mounting hole 6 to reduce the entry of impurities; then open the inner cover 4, and use the second opening 28 on the wall of the through hole 3 of the upper cover 2 to apply force so that the second snap tooth 21 of the inner cover 4 disengages from the second snap hole 23 of the through hole 3. Then, flip the inner cover 4 around the hinge structure formed by the second rotating shaft 20 and the second mounting hole 22 of the inner cover 4 and the through hole 3. The first flexible sealing ring 10 in the first mounting groove 9 at the bottom of the inner cover 4 moves with the inner cover 4, and its sealing ring 11 no longer adheres to the sealing surface 12 of the inner wall of the through hole 3 of the upper cover 2. The tank 1 communicates with the outside through the through hole 3. Then, holding the measuring spoon 7, scoop the contents of the can 1 through the through hole 3 of the upper cover 2. After scooping, first reset the inner cover 4 so that the second snap tooth 21 snaps into the second snap hole 23. At the same time, the sealing ring 11 of the first flexible sealing ring 10 fits tightly with the sealing surface 12 of the inner wall of the through hole 3, thus sealing the inner cover 4 with the upper cover 2. Then, put the measuring spoon 7 back into the spoon mounting hole 6 of the inner cover 4, close the cover 8, and ensure that the first snap tooth 16 snaps tightly with the first snap hole 18. Finally, check whether the second flexible sealing ring 14 in the annular groove 13 at the bottom of the upper cover 2 is intact, and confirm that the connecting block 24 in the outer circle direction of the upper cover 2 is securely connected to the limiting ring 26 at the outer circle of the can 1 through the mounting tooth 25, thus completing the overall sealed storage of the packaging can.
