Description

Technical Field

[0001] This application relates to the field of consumer goods technology, and in particular to a flip-top sealed container. Background Technology

[0002] As people's living standards improve, the demand for storing various foods and medicines is increasing, making airtight containers, as a common storage container, increasingly important. While existing airtight container technology meets daily storage needs to a certain extent, some problems still exist.

[0003] On the one hand, some sealed containers have relatively simple sealing structures, relying mainly on a single sealing ring or gasket to achieve a sealing effect. This single sealing method often fails to provide sufficient sealing protection for some volatile or moisture-sensitive items, leading to easy spoilage or contamination from the external environment. For example, some medicines or essential oils containing volatile components will have reduced efficacy or lower quality if not properly sealed.

[0004] On the other hand, the connection between the lid and the container of the sealed container is not robust enough. During frequent opening and closing, the lid is prone to loosening, falling off, or even being damaged. This not only inconveniences the user but may also lead to leakage of the contents, causing unnecessary losses and environmental pollution.

[0005] In addition, some airtight containers are not designed with user experience in mind. The opening and closing operation is cumbersome and requires a lot of strength, which is extremely inconvenient for users with weak hand strength, such as the elderly or children, thus limiting the scope of application of airtight containers.

[0006] Related prior art, such as Chinese patent application "A Sealed Can Structure", publication number: CN214453396U, discloses a can body and a sealing cap assembly. The sealing cap assembly is installed on the can body. The sealing cap assembly includes a sealing component adapted to the can body, an outer cover sleeved on the upper end of the sealing component, and a flip cover installed on the outer cover. One end of the flip cover is connected to a switch latch, which is movably connected to the outer cover. Both end faces of the switch latch are provided with a first protrusion, a notch, and a second protrusion in sequence.

[0007] The sealing can structure of the aforementioned patent application has a complex design in the connection structure of the sealing cap assembly. The connection structure between the flip cover, the switch latch, and the outer cover is not reliable enough. During frequent opening and closing, the cap is prone to loosening or falling off. Utility Model Content

[0008] The technical problem to be solved by this application is to provide a flip-type sealing can that improves the reliability of the sealing structure and the connection structure, while taking into account the ease of operation, so as to meet the needs of different users.

[0009] The technical solution adopted in this application is: a flip-type sealing can, including a can body and a sealing cap assembly. The sealing cap assembly includes a handle, an upper cover, a middle cover and a lower cover. The surface of the upper cover is provided with a groove, and the handle is accommodated in the groove. The middle cover is installed below the upper cover and is covered with a sealing ring. The top of the lower cover protrudes through the groove and is connected to the handle through a pivot. Flipping the handle changes the height of the pivot, thereby changing the height of the lower cover. The outer edge of the lower cover is embedded in the inner wall of the sealing ring. The change in the height of the lower cover changes the outer diameter of the sealing ring.

[0010] Compared with existing technologies, the advantages of this application are that the outer diameter of the sealing ring can be changed by varying the height of the lower cover, thus forming a seal between the sealing cover assembly and the can body. When the outer diameter of the sealing ring increases, it fits tightly against the inner wall of the can, effectively preventing the intrusion of external factors such as air and moisture, ensuring a stable storage environment for the items. This is particularly suitable for storing volatile and moisture-sensitive items, and can better maintain the efficacy of medicines and the quality of essential oils. When the outer diameter of the sealing ring decreases, the seal between the sealing cover assembly and the can body is released. In this application, the sealing ring is designed as a non-moving structure, effectively improving the reliability and stability of the sealing structure.

[0011] Flipping the handle directly changes the height of the lower cover, controlling the sealing state. Operation is simple and effortless, requiring no complicated steps or excessive force, making it suitable for users with varying hand strength and improving the versatility and ease of use of the sealing container. In the horizontal position, the handle is concealed within a recess in the upper cover, saving space and maintaining a clean appearance; in the vertical position, the handle provides a better grip, optimizing the user experience.

[0012] In some embodiments of this application, the top surface of the tank is open, the sealing cap assembly covers the opening on the top surface of the tank, and the sealing ring and the lower part of the lower cover extend into the tank body. When the sealing ring is in its large outer diameter state, it fits snugly against the inner wall of the tank to achieve a sealed connection; when the sealing ring is in its small outer diameter state, a gap exists between the outer ring of the sealing ring and the inner wall of the tank, releasing the seal. By extending the sealing ring and the lower part of the lower cover into the tank body, sealing or releasing is achieved by utilizing the change in the outer diameter of the sealing ring. The structure is compact and has a large sealing contact area, improving sealing reliability. At the same time, it ensures that the sealing surface is evenly stressed during operation, extending the life of the sealing ring.

[0013] In some embodiments of this application, an embedded ring is provided on the outer edge of the lower cover. The embedded ring is located above the bottom surface of the lower cover, and its outer surface is a frustum-shaped structure with a top diameter smaller than its bottom diameter. When the lower cover is in a high position, the lower part of the embedded ring extends into the sealing ring, expanding the outer diameter of the sealing ring. When the lower cover is in a low position, the embedded ring exits the sealing ring, reducing the outer diameter of the sealing ring. The frustum-shaped embedded ring gradually expands or releases the sealing ring during the raising and lowering of the lower cover, making the change in outer diameter smooth and uniform, avoiding excessive local stretching and deformation of the sealing ring, enhancing sealing stability, and reducing component wear.

[0014] In some embodiments of this application, the longitudinal section of the sealing ring is an inverted L-shaped structure. The sealing ring includes a mounting portion at the top and a sealing portion surrounding the outer periphery below the top. The inverted L-shaped structure is fixed to the middle cover by the top mounting portion, and the sealing portion hangs down naturally to fit against the inner wall of the tank, forming a double sealing interface (lateral and longitudinal), which improves the sealing effect, and the L-shaped structure has stronger resistance to deformation.

[0015] In some embodiments of this application, the sealing ring is connected to the middle cover via a mounting part, which is embedded inside the middle cover. The sealing part is at least partially attached to the outer surface of the embedded ring. The mounting part is embedded inside the middle cover to achieve physical locking, preventing the sealing ring from shifting or falling off during use, ensuring that the sealing part is always aligned with the inner wall of the tank, maintaining sealing consistency, and reducing the risk of leakage due to assembly errors.

[0016] In some embodiments of this application, the bottom surface of the upper cover is provided with a plurality of buckles, and the surface of the middle cover is provided with corresponding slots for the buckles. The upper cover and the middle cover are engaged by the buckles passing through the slots. The engagement of the buckles and slots enables quick assembly and disassembly without the need for additional tools, reducing production costs; multiple engagement structures distribute the force, enhancing the connection strength between the upper cover and the middle cover and preventing loosening caused by frequent opening and closing.

[0017] In some embodiments of this application, the pivot is located at the corner above the handle. When the handle is horizontal, the pivot is in a high position; when the handle is vertical, the pivot is in a low position. The switching between the high and low positions of the pivot utilizes the lever principle, achieving a significant lifting and lowering of the lower cover with a small operating force, which is labor-saving and efficient. The corner layout optimizes the lever arm length, further improving the ease of operation.

[0018] In some embodiments of this application, the handle in a horizontal state is located within a groove, which has a D-shaped structure. The handle is designed to fit the groove, with a predetermined distance between one side of the handle and the sidewall of the groove, and the other three sides of the handle are positioned close to the sidewall of the groove. The D-shaped groove and the three sides of the handle fit together to save space and make the handle appear flat when stored; the reserved distance on one side makes it easier for fingers to grip the handle, taking into account both aesthetics and human-computer interaction.

[0019] In some embodiments of this application, four springs are regularly arranged between the middle cover and the lower cover. The upper end of the spring is connected to the middle cover, and the lower end of the spring is connected to the lower cover. The springs provide a force to the lower cover to move away from the middle cover.

[0020] Specifically, this application uses irregularly shaped springs. Four springs are evenly distributed to provide balanced elastic force, ensuring smooth lifting and lowering of the lower cover and avoiding tilting and jamming; the spring force assists in the lower cover's reset, reducing the user's operational effort and enhancing the reliability of the sealing state switching.

[0021] In some embodiments of this application, a rectangular frame-shaped connector protrudes upward from the center of the middle cover. The top of the connector extends through a groove and connects to the handle via a pivot. The rectangular frame structure enhances the rigidity of the middle cover and prevents the pivot from deforming under stress. The connector extends through the groove and directly links to the handle, reducing the number of transmission components, lowering the failure rate, and improving the overall reliability of the structure.

[0029] The present application will now be described in detail with reference to the accompanying drawings.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] Tumbler-type sealing container, Example 1 as follows Figures 1 to 2 As shown: The container includes a can body 1 and a sealing cap assembly 2. The sealing cap assembly 2 includes a handle 3, an upper cover 4, a middle cover 5, and a lower cover 6. The upper cover 4 has a groove 7 on its surface, which accommodates the handle 3. The middle cover 5 is installed below the upper cover 4 and is fitted with a sealing ring 8. The top of the lower cover 6 protrudes from the groove 7 and is connected to the handle 3 via a pivot 9. Flipping the handle 3 directly changes the height of the lower cover 6, controlling the sealing state. Operation is simple and effortless, requiring no complicated steps or excessive force, making it convenient for users with varying hand strength, thus improving the applicability and ease of use of the sealing container. In the horizontal position, the handle 3 is concealed within the groove 7 of the upper cover 4, saving space and maintaining a clean appearance; in the vertical position, the handle 3 is easy to grip, optimizing the user experience.

[0032] Flipping the handle 3 changes the height of the pivot 9, thus altering the height of the lower cover 6. The outer edge of the lower cover 6 is embedded in the inner wall of the sealing ring 8. The change in the height of the lower cover 6 changes the outer diameter of the sealing ring 8, forming a seal between the sealing cover assembly 2 and the container 1. When the outer diameter of the sealing ring 8 increases, it fits tightly against the inner wall of the container 1, effectively preventing the intrusion of external factors such as air and moisture, ensuring a stable storage environment for the items. This is particularly suitable for storing volatile and moisture-sensitive items, and can better maintain the efficacy of medicines and the quality of essential oils. When the outer diameter of the sealing ring 8 decreases, the seal between the sealing cover assembly 2 and the container 1 is released. In this application, the sealing ring 8 is designed as a non-moving structure, effectively improving the reliability and stability of the sealing structure in this application.

[0033] Example 2, as Figures 1 to 4 As shown, the top surface of the tank 1 is open, and the sealing cap assembly 2 covers the opening on the top surface of the tank 1. The sealing ring 8 and the lower part of the lower cover 6 extend into the tank 1. When the sealing ring 8 is in its large outer diameter state, it fits against the inner wall of the tank 1 to achieve a sealed connection. When the sealing ring 8 is in its small outer diameter state, there is a gap between the outer ring of the sealing ring 8 and the inner wall of the tank 1, thus releasing the seal. By extending the sealing ring 8 and the lower part of the lower cover 6 into the tank 1, the sealing or release is achieved by utilizing the change in the outer diameter of the sealing ring 8. The structure is compact and has a large sealing contact area, improving sealing reliability. At the same time, it ensures that the sealing surface is evenly stressed during operation, extending the life of the sealing ring 8.

[0034] An embedded ring 10 is provided on the outer edge of the lower cover 6. The embedded ring 10 is located above the bottom surface of the lower cover 6, and its outer surface is a frustum structure with a top diameter smaller than its bottom diameter. When the lower cover 6 is in the high position, the lower part of the embedded ring 10 extends into the sealing ring 8, expanding the outer diameter of the sealing ring 8. When the lower cover 6 is in the low position, the embedded ring retracts from the sealing ring 8, reducing the outer diameter of the sealing ring 8. The frustum-shaped embedded ring 10 gradually expands or releases the sealing ring 8 when the lower cover 6 is raised or lowered, making the change in outer diameter smooth and uniform, avoiding excessive local stretching and deformation of the sealing ring 8, enhancing sealing stability, and reducing component wear.

[0035] The longitudinal section of the sealing ring 8 is an inverted L-shaped structure. The sealing ring 8 includes a mounting part 8a at the top and a sealing part 8b that wraps around the outer periphery below the top. The inverted L-shaped structure is fixed to the middle cover 5 by the top mounting part 8a, and the sealing part 8b hangs down naturally to fit against the inner wall of the tank 1, forming a double sealing interface (lateral and longitudinal), which improves the sealing effect, and the L-shaped structure has stronger resistance to deformation.

[0036] The sealing ring 8 is connected to the middle cover 5 via the mounting part 8a, which is embedded inside the middle cover 5. The sealing part 8b is at least partially attached to the outer surface of the embedded ring 10. The mounting part 8a is embedded inside the middle cover 5 to achieve physical locking, preventing the sealing ring 8 from shifting or falling off during use, ensuring that the sealing part 8b is always aligned with the inner wall of the tank 1, maintaining sealing consistency, and reducing the risk of leakage due to assembly errors.

[0037] The bottom surface of the upper cover 4 is provided with several buckles, and the surface of the middle cover 5 is provided with corresponding slots for the buckles. The upper cover 4 and the middle cover 5 are connected by the buckles passing through the slots. The cooperation of the buckles and slots enables quick assembly and disassembly without additional tools, reducing production costs; multiple connection structures distribute the force, enhance the connection strength between the upper cover 4 and the middle cover 5, and avoid loosening caused by frequent opening and closing.

[0038] The pivot 9 is located at the corner above the handle 3. When the handle 3 is horizontal, the pivot 9 is in the high position; when the handle 3 is vertical, the pivot 9 is in the low position. The switching between the high and low positions of the pivot 9 utilizes the lever principle to achieve a large lifting and lowering of the lower cover 6 with a small operating force, which is labor-saving and efficient. The corner layout optimizes the lever arm length, further improving the ease of operation.

[0039] In its horizontal position, the handle 3 is located within the groove 7, which has a D-shaped structure. To accommodate the structure of the groove 7, one side of the handle 3 has a predetermined distance from the sidewall of the groove 7, while the other three sides of the handle 3 are positioned close to the sidewall of the groove 7. This D-shaped groove 7 and the three sides of the handle 3 fit together to save space and ensure a flat appearance when the handle 3 is stored. The reserved distance on one side makes it easier to pick up the handle 3 with your fingers, balancing aesthetics and user-friendliness.

[0040] Four springs 11 are regularly arranged between the middle cover 5 and the lower cover 6. The upper end of each spring 11 is connected to the middle cover 5, and the lower end of each spring 11 is connected to the lower cover 6. The springs 11 provide a force to the lower cover 6 to move away from the middle cover 5. Specifically, this application uses irregularly shaped springs 11. The four springs 11 are evenly distributed to provide balanced elastic force, ensuring smooth lifting and lowering of the lower cover 6 and avoiding tilting and jamming. The force of the springs 11 assists the lower cover 6 in resetting, reducing the user's operating effort and enhancing the reliability of the sealing state switching.

[0041] The middle cover 5 has a rectangular frame-shaped connector 12 protruding upward from its center. The top of the connector 12 extends through a groove 7 and connects to the handle 3 via a pivot 9. The rectangular frame structure enhances the rigidity of the middle cover 5 and prevents the pivot 9 from deforming under stress. The connector 12 extends through the groove 7 and directly links to the handle 3, reducing the number of transmission components, lowering the failure rate, and improving the overall reliability of the structure.

[0042] The rest of the contents of Example 2 are the same as those of Example 1.

[0043] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
