Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and more specifically to a cup lid valve structure and a container having the same. Background Technology

[0002] The production and storage of fermented foods such as kimchi and enzymes, as well as the preservation of dried goods, typically require a vacuum environment within sealed containers to inhibit bacterial growth and extend shelf life. This has led to the development of vacuum containers. The core component of these containers is the valve structure located on the lid, whose performance directly determines the container's sealing reliability, ease of operation, and lifespan.

[0003] Currently, common cup lid valve structures have the following main shortcomings:

[0004] Complex operation and limited function: Many traditional gas valves use a simple push-button plug structure. This structure usually only has basic sealing function and cannot release gas quickly and controllably when the internal pressure of the container is too high. There is a risk that the cap may be difficult to open due to excessive internal pressure or even that the gas and contents may splash out.

[0005] Insufficient sealing reliability, especially in the inverted state: Some valves have a good sealing effect when the container is upright, but when the container is inverted, the liquid contents may seep into the valve body, or the valve core may shift due to internal pressure or external squeezing, damaging the sealing surface and causing leakage, thus causing the vacuum environment to fail.

[0006] Complex structure: Some improved air valves attempt to switch between sealing and venting functions through multiple independent locking components, resulting in an increased number of parts and a more complex assembly process.

[0007] Therefore, how to provide a cup lid valve structure that is simple in structure, integrates vacuuming, reliable sealing, and convenient venting functions, and can effectively prevent leakage when inverted is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the present invention provides a cup lid valve structure and a container having the same, in order to solve the above-mentioned technical problems.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A cup lid valve structure includes:

[0011] The cup lid body has a through hole on its top surface and an annular seat that extends axially and coaxially with the through hole on its inner bottom surface.

[0012] The elastic valve core has its upper part in contact with the upper surface of the annular seat, and its lower part penetrates the annular seat and extends to the outside of the annular seat.

[0013] A washer, wherein the washer is engaged on the upper surface of the elastic valve core, and one end of the upper surface of the washer has a protrusion;

[0014] The movable column has its bottom passing through a washer and extending into the elastic valve core, with a closing ring hinged to its top. The closing ring can rotate around the hinge point to abut or disengage from the protrusion. When the closing ring abuts against the protrusion, the movable column is pulled upward, thereby pressing the bottom of the elastic valve core against the bottom end face of the annular seat for a tight seal. When the closing ring disengages from the protrusion, the movable column is pressed downward, thereby creating a gap between the bottom of the elastic valve core and the bottom end face of the annular seat.

[0015] Through the above technical solution, the cup lid valve structure provided by this utility model can quickly switch between "sealing" and "gap formation" states through the flipping action of a single component—the closing ring. Folding upwards and abutting against the protrusion achieves a seal, while folding it off opens the gap. It integrates three major functions: vacuuming, sealing and pressure holding, and rapid gas release, making operation extremely simple and intuitive. The arc-shaped surface at the hinge of the closing ring and the transition slope of the gasket cooperate with each other, making the flipping process smooth and effortless, and efficiently converting the flipping motion into the vertical lifting of the movable column. When the internal pressure of the container increases, the air pressure acts on the sealing part at the bottom of the elastic valve core, generating an additional force in the same direction as the lifting force. This makes the sealing part and the bottom edge of the annular seat press tighter, forming a self-reinforcing effect of "the higher the internal pressure, the tighter the seal." This significantly improves the sealing reliability under high-pressure conditions such as fermentation and inversion. This invention achieves multiple functions through the mechanical linkage of a few core components such as the elastic valve core, the moving column, and the closing ring, eliminating multiple independent locking parts. This not only simplifies the structure and reduces manufacturing costs but also reduces failure points and improves overall durability and reliability.

[0016] Preferably, in the above-described cup lid valve structure, the elastic valve core includes an integrally formed sealing seat and a connecting post. The sealing seat fits against the upper surface of the annular seat, and the bottom of the connecting post penetrates through the through hole and the annular seat, with a radially protruding limiting portion at its bottom. The outer diameter of the limiting portion is larger than the inner diameter of the central through hole of the annular seat. The integrally formed sealing seat and connecting post structure enhances the overall structural integrity and strength, and simplifies production and assembly. The limiting portion prevents the movable post from excessively pulling the elastic valve core when pulled upwards, thus avoiding the elastic valve core from dislodging.

[0017] Preferably, the above-described cup lid valve structure further includes an elastic buckle clamped to the outside of the limiting portion. The elastic buckle works in conjunction with the limiting portion at the bottom of the movable column to effectively prevent the movable column from falling out of the elastic valve core during frequent pressing or vibration.

[0018] Preferably, in the above-described cup lid valve structure, the sealing part includes an annular rib protruding radially from the outer side wall of the connecting post, the annular rib being located between the limiting part and the bottom end face of the annular seat. As a line contact seal, the annular rib can generate greater pressure under the same pulling force, making the sealing faster and more effective, significantly reducing the risk of leakage and ensuring airtightness.

[0019] Preferably, in the above-described cup lid valve structure, the top surface of the sealing seat has a toggle part. After vacuuming, the inside of the tank is in a low-pressure state. The toggle part provides a manual pressure relief function. When the user wants to quickly relieve pressure, they can directly pull the toggle part upward to lift the valve core and achieve pressure relief.

[0020] Preferably, in the above-mentioned cup lid valve structure, the side wall of the sealing seat has a first protrusion corresponding to the actuating part, the top surface of the cup lid body has an installation groove, the through hole is opened in the center of the installation groove, and the side wall of the through hole has a second protrusion corresponding to the first protrusion. The second protrusion has curved slopes on both sides, and the first protrusion has a corresponding chamfer. When the elastic valve core rotates to the corresponding position of the second protrusion, the chamfer of the first protrusion can climb along the curved slope of the second protrusion, forcibly lifting the sealing seat and creating a gap between the sealing seat and the upper surface of the annular seat. Through the cooperation of the slopes of the first and second protrusions, rotating the elastic valve core can forcibly lift the sealing seat, forming a stable gap channel between the sealing seat and the upper surface of the annular seat. This function can be adapted to external vacuum / intake equipment to achieve repeated vacuuming and intake circulation, which is particularly suitable for scenarios that need to promote fermentation or pickling, making the processing more thorough. Reverse rotation will reset the sealing seat by going downhill, making the sealing seat fit against the upper surface of the annular seat. It has the function of rotating to a specific position, and reverse rotation will reset it smoothly. The state switching is clear and reliable.

[0021] Preferably, in the above-described cup lid valve structure, the upper surface of the cup lid body has a marking point corresponding to the position of the second protrusion. The marking point design provides users with clear and intuitive visual guidance, enabling users to accurately rotate the elastic valve core to the working position (i.e., the position that forms the circulation ventilation gap), greatly improving the ease of use of the product and the user experience.

[0022] This utility model also provides a container, including a container body and the aforementioned cup lid valve structure detachably connected to the container body. By integrating any of the above-mentioned cup lid valve structures, the container possesses advanced functions such as easy operation, reliable sealing, easy venting, and even gas circulation, significantly enhancing its practical value in food fermentation, preservation, and storage.

[0023] Preferably, in the above-mentioned container, the container body has silicone partitions. These silicone partitions can divide the interior of the container, facilitating the categorized storage of different items, or act as a pressure tray to prevent contents from floating, thus optimizing storage space.

[0024] Preferably, in the above-mentioned container, the bottom of the container body has a silicone pad. The silicone pad at the bottom of the container body can play a role in preventing slipping, absorbing shock, and preventing scratches on the countertop, thereby improving the stability and safety of the container during use and placement.

[0025] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a cup lid valve structure and a container having the same, which has the following beneficial effects:

[0026] 1. This utility model provides a highly integrated and easy-to-operate gas valve switching mechanism. By simply flipping the closed ring, the internal movable column can be driven to move up and down, thereby controlling the sealing or separation between the elastic valve core and the annular seat. This achieves one-button switching of three major functions: vacuuming, pressure sealing, and rapid gas release. This not only greatly simplifies the user's operation steps, but also, through ingenious structural design, enables the sealing effect to be self-reinforced when the internal pressure of the container increases, effectively solving the technical problem of easy leakage of traditional gas valves under high-pressure environments such as fermentation and inversion.

[0027] 2. The integrated design of the elastic valve core in this utility model enhances structural strength, while the cooperation between the limiting part and the elastic buckle prevents moving parts from falling off during frequent use. In particular, the introduction of the annular rib generates greater pressure under the same force through line contact sealing, ensuring rapid and reliable sealing. These designs collectively improve the overall durability of the product, enabling it to withstand long-term, frequent state switching without easily being damaged.

[0028] 3. By incorporating rotatable, aligned protrusions and clear markings, this invention allows users to not only achieve basic airtight control but also actively open a stable gap channel to accommodate external equipment for circulating air extraction and intake. This function is particularly suitable for scenarios requiring controlled fermentation processes, resulting in more thorough and uniform pickling or fermentation, thus meeting users' demands for more refined and advanced food processing.

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] See appendix Figure 1 To be continued Figure 7 This utility model discloses a cup lid valve structure, comprising:

[0043] The cup lid body 1 has a through hole 11 on its top surface and an annular seat 2 that extends axially and is coaxially connected to the through hole 11 on its inner bottom surface.

[0044] The upper part of the elastic valve core 3 is in contact with the upper surface of the annular seat 2; and its lower part penetrates the annular seat 2 and extends to the outside of the annular seat 2.

[0045] Washer 4 is fitted onto the upper surface of the elastic valve core 3, and one end of the upper surface of washer 4 has a protrusion 41.

[0046] The movable column 5 has its bottom passing through the washer 4 and extending into the elastic valve core 3. Its top is hinged with a closing ring 6, which can rotate around the hinge point to abut or disengage from the protrusion 41. When the closing ring 6 abuts with the protrusion 41, the movable column 5 is pulled upward, thereby causing the bottom of the elastic valve core 3 to press tightly against the bottom end face of the annular seat 2 for sealing. When the closing ring 6 disengages from the protrusion 41, the movable column 5 is pressed downward, thereby creating a gap between the bottom of the elastic valve core 3 and the bottom end face of the annular seat 2.

[0047] Specifically, the elastic valve core 3 is made of silicone.

[0048] In some specific examples, the resilient valve core 3 includes an integrally formed sealing seat 31 and a connecting post 32. The sealing seat 31 fits against the upper surface of the annular seat 2. The bottom of the connecting post 32 passes through the through hole 11 and the annular seat 2, and its bottom has a radially protruding limiting part 33. The outer diameter of the limiting part 33 is larger than the inner diameter of the central through hole of the annular seat 2.

[0049] In some other embodiments, an elastic buckle 34 is also included that is held on the outside of the limiting portion 33.

[0050] In a specific embodiment, the sealing part includes an annular rib 35 that protrudes radially from the outer side wall of the connecting column 32, and the annular rib 35 is located between the limiting part 33 and the bottom end face of the annular seat 2.

[0051] Specifically, the annular seat 2 has an axially extending boss 21, and the annular rib 35 abuts against the bottom end face of the boss 21 when it is pressed.

[0052] In a specific example, the top surface of the sealing seat 31 has a toggle part 36.

[0053] In some examples, the side wall of the sealing seat 31 has a first protrusion 311 corresponding to the actuating part 36, the top surface of the cup lid body 1 is provided with a mounting groove 12, the through hole 11 is opened in the center of the mounting groove 12, and the side wall of the through hole 11 has a second protrusion 111 corresponding to the first protrusion 311.

[0054] More specifically, the upper surface of the cup lid body 1 has a marker point 13 at the position corresponding to the second protrusion 111.

[0055] See Figure 8-9 As shown, this utility model also provides a container, including a container body 7 and a cup lid valve structure detachably connected to the container body 7.

[0056] In some specific examples, the tank 7 has a silicone partition 71 inside.

[0057] In other embodiments, the bottom of the can 7 has a silicone pad 72.

[0058] More specifically, the cup lid 1 is threadedly connected to the can body 7, and the inner side of the cup lid 1 has a sealing ring 8.

[0059] The embodiments of this utility model are as follows:

[0060] 1. Sealed and pressure-holding state

[0061] See Figure 1 and Figure 2 When it is necessary to keep the container in a vacuum or sealed state, fold the sealing ring 6 upward from the flat position.

[0062] During the folding process, the arc-shaped surface at the hinge of the closed ring 6 will slide and compress along the transition slope on the washer 4, and this process begins to apply an upward force to the movable column 5.

[0063] When the closed ring 6 is folded to approximately 90°, its lower end abuts against the protrusion 41. At this time, the movable column 5 is pulled upward.

[0064] Since the bottom of the movable column 5 is inserted and fixed to the elastic valve core 3, this lifting force will cause the entire elastic valve core 3 to move upward.

[0065] Ultimately, the sealing portion at the bottom of the resilient valve core 3 (specifically, the annular rib 35) fits tightly against the bottom edge opening of the annular seat 2, achieving a reliable seal (see...). Figure 4 , Figure 5 ).

[0066] Self-reinforcing effect: If the pressure inside the container increases, the high-pressure gas acts on the sealing part, generating an additional upward thrust that is in the same direction as the previous tensile force, thus further enhancing the sealing effect.

[0067] When there is high pressure inside the tank 7 and gas needs to be released, rotate the sealing ring 6 90° to disengage it from the protrusion 41 (at this time, the sealing ring 6 is in the open state). Press the movable column 5 so that the movable column 5 drives the annular rib 35 to move downward, so that the annular rib 35 is no longer in contact with the bottom end face of the annular seat 2 (forming a venting gap), and gas can be released. This solves the problem that in the prior art, the cup lid needs to be opened to release gas, which leads to the splashing of gas and liquid inside the tank.

[0068] 2. Venting / Vacuuming State

[0069] See Figure 1 and Figure 2 When it is necessary to release the internal pressure of the container or to perform a vacuum operation, the sealing ring 6 is folded off from the state of abutting against the protrusion 41.

[0070] At this point, the movable column 5 loses its upward lifting force and moves downward under its own weight or slight external pressure.

[0071] The movable column 5 is pressed down, which drives the elastic valve core 3 to move downward, causing the sealing part (annular rib 35) at its bottom end to separate from the bottom edge opening of the annular seat 2, forming a breathable gap.

[0072] The gas inside the container can be quickly discharged through this gap via through-hole 11, or the internal air can be extracted by an external vacuum device through this gap (see...). Figure 2 ).

[0073] 3. Circulating ventilation state

[0074] The user rotates the resilient valve core 3 by using the toggle part 36, causing the first protrusion 311 on its side wall to align with and climb up the arc-shaped slope of the second protrusion 111 on the side wall of the through hole 11. This climbing action forcibly lifts the entire sealing seat 31 and the resilient valve core 3 connected to it upwards.

[0075] At this point, not only is a venting gap formed at the bottom, but more importantly, a stable and larger gap channel is also formed between the upper surface of the sealing seat 31 and the annular seat 2.

[0076] The marking point 13 set at the corresponding position on the upper surface of the cup lid body 1 provides a clear visual guide for the user to accurately rotate to the working position.

[0077] In this state, it can be adapted to external devices (such as air pumps) to achieve a "vacuum-intake" cycle operation, which is particularly suitable for delicate scenarios that require the injection of inert gas for preservation or to promote fermentation. Reverse rotation of the valve core will reset the first protrusion 311 and reseal it.

[0078] 4. Overall application of containers and tanks

[0079] See Figure 8 and Figure 9 By combining the aforementioned cup lid valve structure with the can body 7, a container can is formed.

[0080] Silicone dividers 71 can be used for partitioned storage or as pressure trays to prevent contents from floating.

[0081] The silicone pad 72 serves to prevent slipping, absorb shock, and protect the desktop.

[0082] The cup lid is connected to the container body by threads, and the main seal is ensured by the sealing ring 8. Together with the gas valve structure, they provide a storage technology solution that is easy to operate, reliable in sealing, and feature-rich.
