Description

Technical Field

[0001] This utility model belongs to the field of sealed container technology, and relates to a sealing cap and a sealed container. Background Technology

[0002] With the improvement of people's living standards and the increasing requirements for the quality of goods preservation, sealed containers are being used more and more widely in the fields of food, medicine, electronic products, and daily necessities. As a key component of sealed containers, the performance of the sealing cap directly affects the airtightness, ease of use, and long-term reliability of the container.

[0003] Currently, most common sealing caps adopt an integral structure, which uses an elastic sealing ring to press tightly against the container opening to achieve functions such as dust prevention, moisture prevention, and oxidation prevention. However, traditional sealing caps have limited functions, mainly focusing on "fully sealed" or "fully open" operation, and cannot flexibly adjust the ventilation state according to actual needs. Because there is a pressure difference between the inside of the container and the outside when it is sealed, negative pressure can easily form when the temperature inside the container changes or a vacuum is drawn, making it difficult to open the cap and resulting in a poor user experience.

[0004] Therefore, some containers are equipped with one-way valves to balance the pressure. However, one-way valves have a complex structure, high cost, and are prone to leakage or failure due to poor sealing. Therefore, there is still considerable room for improvement. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a sealing cap and a sealing container.

[0006] The objective of this utility model can be achieved through the following technical solution: a sealing cap, comprising:

[0007] The cover has a sealing groove, and the side wall of the sealing groove has a vent hole;

[0008] A movable component is movably connected to the cover and located within the sealing groove. The movable component is provided with a sealing part. When the movable component moves, it drives the sealing part to move towards or away from the vent hole, thereby closing or releasing the vent hole.

[0009] In the aforementioned sealing cover, the cover body is further provided with a travel member, and the travel member is further provided with a travel groove. The travel groove includes a first position and a second position. The travel member can be moved to the first position or the second position. When the travel member is in the first position, the sealing part closes the vent hole. When the travel member is in the second position, the sealing part releases the vent hole.

[0010] In one of the sealing caps described above, the travel groove is provided with a first snap-fit ​​protrusion, which is located between the first position and the second position. The first snap-fit ​​protrusion restricts the travel member from leaving the first position or entering the first position from other positions in the travel groove.

[0011] In the aforementioned sealing cover, the cover body is further provided with a first limiting member, and the movable member is further provided with a first limiting groove. When the travel member is located in the first position, the first limiting member is located in the first limiting groove.

[0012] In one of the sealing caps described above, the travel groove is provided with a second snap-fit ​​protrusion, which is located between the first position and the second position. The second snap-fit ​​protrusion restricts the travel member from leaving the second position or from entering the second position from other positions in the travel groove.

[0013] In the aforementioned sealing cover, the cover body is further provided with a second limiting member, and the movable member is further provided with a second limiting groove. When the travel member is in the second position, the second limiting member is located in the second limiting groove.

[0014] In one of the sealing caps described above, the movable member has a handle portion protruding from its top surface.

[0015] In one of the sealing caps described above, the cap body has a decorative portion protruding from its top surface, and the handle portion is aligned with the decorative portion when the travel member is in the first position.

[0016] In one of the sealing caps described above, the sealing part is configured as a sealing element, which is detachably connected to the movable part.

[0017] Secondly, a sealed container, including the aforementioned sealing cover, further includes: a box body, the cover body being provided with a sealing ring, the cover body being detachably connected to the box body and contacting the box body through the sealing ring, a storage space being formed between the cover body and the box body, the storage space being connected to the outside through the vent hole.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: When the moving component moves, it drives the sealing part to move closer to or further away from the vent, thereby closing or releasing the vent, achieving dynamic control of the vent and switching between sealing and ventilation states. This balances pressure and prevents the cover from being difficult to remove due to negative pressure or difficult to close due to positive pressure during use. Through the cooperation of the travel component and the travel groove, precise guidance and position control of the moving component are achieved. When the travel component is in the first position, the sealing part closes the vent; when the travel component is in the second position, the sealing part releases air. The hole allows for intuitive operation and accurate positioning, preventing misoperation. The first locking protrusion restricts the travel member from leaving the first position or entering the first position from other positions in the travel groove, stably locking the travel member in the first position, i.e., the sealing cover is in a sealed state, preventing the sealing part from accidentally dislodging from the vent hole due to external force, thus ensuring the durability of the seal. Through the cooperation of the first limiting member and the first limiting groove, together with the first locking protrusion, a double locking mechanism is formed, further enhancing the stability of the moving part in the first position. This structure effectively prevents the moving part from shifting in the sealed state, further ensuring the durability of the seal. Attached Figure Description

[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0034] like Figures 1-7 As shown, a sealing cover includes: a cover body 100 and a movable part 200.

[0035] The cover 100 is provided with a sealing groove 110, and the side wall of the sealing groove 110 is provided with a vent hole 111.

[0036] The movable component 200 is movably connected to the cover 100 and located in the sealing groove 110. The movable component 200 is provided with a sealing part. When the movable component 200 moves, it drives the sealing part to move towards or away from the vent hole 111, thereby sealing or releasing the vent hole 111.

[0037] In this embodiment, when the moving part 200 moves, it drives the sealing part to move towards or away from the vent 111, thereby sealing or releasing the vent 111, realizing dynamic control of the vent 111, switching between the two states of sealing and ventilation, thereby balancing the pressure and preventing the cover 100 from being difficult to remove due to negative pressure or difficult to put on due to positive pressure during use.

[0038] like Figures 1-7 As shown, based on the above embodiment, the cover 100 is further provided with a travel member 120, and the moving member 200 is further provided with a travel groove 220. The travel groove 220 includes a first position and a second position. The travel member 120 can be moved to the first position or the second position. When the travel member 120 is in the first position, the sealing part closes the vent hole 111. When the travel member 120 is in the second position, the sealing part releases the vent hole 111.

[0039] In this embodiment, the precise guidance and position control of the moving part 200 are achieved through the cooperation of the stroke member 120 and the stroke groove 220. When the stroke member 120 is in the first position, the sealing part closes the vent hole 111. When the stroke member 120 is in the second position, the sealing part releases the vent hole 111. The operation is intuitive and the positioning is accurate, avoiding misoperation.

[0040] like Figures 1-7As shown, based on the above embodiment, the travel groove 220 is provided with a first snap-fit ​​protrusion 221. The first snap-fit ​​protrusion 221 is located between the first position and the second position. The first snap-fit ​​protrusion 221 restricts the travel member 120 from leaving the first position or entering the first position from other positions of the travel groove 220.

[0041] In this embodiment, the first snap-fit ​​protrusion 221 restricts the travel member 120 from leaving the first position or entering the first position from other positions of the travel groove 220, which can stably lock the travel member 120 in the first position, that is, the sealing cover is in a sealed state, preventing the sealing part from accidentally dislodging from the vent hole 111 due to external force, thereby ensuring the durability of the seal.

[0042] like Figures 1-7 As shown, based on the above embodiment, the cover 100 is further provided with a first limiting member 130, and the moving member 200 is further provided with a first limiting groove 230. When the travel member 120 is in the first position, the first limiting member 130 is located in the first limiting groove 230.

[0043] In this embodiment, the cooperation between the first limiting member 130 and the first limiting groove 230, together with the first snap-fit ​​protrusion 221, forms a double locking mechanism, which further enhances the stability of the moving member 200 in the first position. This structure effectively prevents the moving member 200 from shifting in the sealed state, and further ensures the durability of the seal.

[0044] like Figures 1-7 As shown, based on the above embodiment, the travel groove 220 is provided with a second snap-fit ​​protrusion 222, which is located between the first position and the second position. The second snap-fit ​​protrusion 222 restricts the travel member 120 from leaving the second position or entering the second position from other positions of the travel groove 220.

[0045] In this embodiment, the second snap-fit ​​protrusion 222 restricts the travel member 120 from leaving the second position or entering the second position from other positions of the travel groove 220, and can stably lock the travel member 120 in the second position, that is, the sealing cover is in a ventilated state, preventing the sealing part from accidentally blocking the vent hole 111 due to external force, thereby ensuring the persistence of ventilation.

[0046] like Figures 1-7 As shown, based on the above embodiment, the cover 100 is further provided with a second limiting member 140, and the moving member 200 is further provided with a second limiting groove 240. When the travel member 120 is in the second position, the second limiting member 140 is located in the second limiting groove 240.

[0047] In this embodiment, the second limiting member 140 and the second limiting groove 240 cooperate with the second snap-fit ​​protrusion 222 to form a double locking mechanism, which further enhances the stability of the moving member 200 in the second position. This structure effectively prevents the moving member 200 from shifting in the ventilated state, and further ensures the durability of the ventilation.

[0048] like Figures 1-7 As shown, based on the above embodiment, the movable member 200 has a handle portion 250 protruding from its top surface.

[0049] In this embodiment, the handle 250 protruding from the top surface of the movable member 200 significantly improves the ease of operation for the user. The user can easily squeeze the handle 250 to push the movable member 200 to switch between sealed and ventilated states.

[0050] like Figures 1-7 As shown, based on the above embodiment, the cover 100 has a decorative portion 150 protruding from its top surface, and when the travel member 120 is in the first position, the handle portion 250 is aligned with the decorative portion 150.

[0051] In this embodiment, when the sealing cap is in a sealed state, the handle 250 and the decorative part 150 are aligned to form a complete and beautiful appearance outline, enhancing the overall texture and visual unity of the product.

[0052] like Figures 1-7 As shown, based on the above embodiment, the sealing part is configured as a sealing member 210, and the sealing member 210 is detachably connected to the moving member 200.

[0053] In this embodiment, the sealing part is designed as a detachable independent sealing element 210, which facilitates later maintenance and replacement. When the sealing element 210 has problems due to long-term use, it is not necessary to replace the entire moving part 200 or the cover 100. The sealing performance can be restored simply by removing the old part and installing the new part, which reduces maintenance costs.

[0054] like Figures 1-8 As shown, a sealed container includes the aforementioned sealing cover and further includes a box body 300. The cover body 100 is also provided with a sealing ring 160. The cover body 100 is detachably connected to the box body 300 and contacts the box body 300 through the sealing ring 160. A storage space is formed between the cover body 100 and the box body 300, and the storage space is connected to the outside through the vent hole 111.

[0055] In this embodiment, the sealing cap is applied to the sealed container to achieve controllable sealing and ventilation of the storage space. The sealing ring 160 ensures a basic seal between the cap 100 and the box 300. The internal air pressure can be flexibly adjusted by operating the sealing cap (such as releasing negative pressure before opening the cap) to avoid the "cap suction" phenomenon. At the same time, it can maintain a sealed, moisture-proof, dust-proof, and oxidation-proof environment when needed.
