Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a container lid and a cooking utensil. Background Technology
[0002] Cooking utensils typically consist of a container body and a lid. The lid fits snugly against the container body, sealing its interior and allowing food to cook quickly. However, in existing technologies, the seal between the lid and the container body is often poor, allowing heat to leak between them during use, thus affecting cooking efficiency. Utility Model Content
[0003] This application provides a container lid and a cooking utensil, the sealing element of which can improve the sealing effect of the cooking container and increase cooking efficiency.
[0004] In a first aspect, this application provides a container lid, the container lid comprising: a lid body and a sealing element, the sealing element being installed on the lid body;
[0005] The sealing element has a deformation cavity and includes a clamping part that clamps and presses against the cover to prevent the sealing element from detaching from the cover.
[0006] In this design, when the container lid is closed onto the container body, the seal contacts the container body. Under pressure from both the lid and the container body, the deformation cavity provides sufficient deformation space for the seal. The seal has a large deformable range, allowing it to withstand higher pressure and impact forces. Furthermore, due to its large deformable range, the seal can fill small gaps between the lid and the container body during deformation, further improving the sealing effect. Simultaneously, the clamping part of the seal holds and presses against the lid, preventing the lid from detaching from the seal and causing sealing failure under external impact, thus ensuring the stability and reliability of the container lid during use.
[0007] In one possible design, the seal includes a first main body portion and a second main body portion connected to each other along the height direction of the container lid, the clamping portion being disposed on the first main body portion, and the second main body portion and the first main body portion forming the deformable cavity.
[0008] In this design, by arranging a first main body and a second main body interconnected along the height direction of the container lid, the clamping part and the deformation cavity are distributed along the height direction of the container lid. Therefore, when the container lid is closed onto the container body, the clamping part, after gripping the lid, can transmit the pressure of the lid downwards along the height direction, promoting the deformation of the deformation cavity and thus improving the sealing reliability between the container lid and the container body. When the deformation cavity is enclosed by the first main body and the second main body, the deformation cavity is more easily deformed, further improving the sealing reliability between the container lid and the container body.
[0009] In one possible design, the clamping portion includes at least two clamping segments with a gap between the ends of the at least two clamping segments, and a portion of the cover can extend into the gap;
[0010] The clamping section is inclined toward the second main body.
[0011] In this design, at least two clamping sections are arranged opposite each other, with a gap between them, and the clamping sections extend towards the second main body. The clamping sections extending towards the second main body act as guides. When the seal is installed on the cover, because the clamping sections extend towards the second main body, the cover's movement direction is the same as the clamping sections, allowing the cover to easily extend through the gap between the clamping sections, thus facilitating the installation of the seal. Simultaneously, when the cover retracts from between the clamping sections, because its movement direction is opposite to the extension direction of the clamping sections, the clamping sections restrict the cover's movement, preventing it from detaching from the gap between the clamping sections, thereby preventing the seal from separating from the cover and improving the reliability of the connection between the cover and the seal.
[0012] In one possible design, the angle between the clamping section and the height direction of the container lid is α, satisfying 30°≤α≤45°.
[0013] In this design, when α is too small, a sharp angle is formed at the connection between the clamping section and the first main body. When the seal is under stress, stress concentration is likely to occur, leading to breakage at the connection between the clamping section and the first main body, thus affecting the service life of the seal. When α is too large, the clamping section is too gentle, resulting in a lack of guiding effect when the cover is inserted. Furthermore, after the cover is inserted, the clamping section has little restraining effect on both sides of the cover, allowing the cover to wobble significantly between the clamping sections, which is detrimental to operational stability. When the cover is withdrawn from between the clamping sections, the friction between the cover and the clamping section is poor because the clamping section and the withdrawal direction of the cover are nearly parallel, making it prone to loosening. When 30°≤α≤45°, while ensuring the service life of the seal, the inclined clamping section provides reliable guidance for the cover during the extension of the cover along the direction of the second main body, reducing assembly resistance. After the cover is extended, it effectively abuts against both sides of the cover, maintaining the stability of the cover. When the cover is withdrawn from between the clamping sections, the downwardly inclined clamping section can prevent the cover from separating from the seal, ensuring the stability of the connection between the cover and the seal.
[0014] In one possible design, the first main body has a cavity into which a portion of the cover can extend through the gap.
[0015] In this solution, when the container body is closed with the container lid and the seal is under pressure, the clamping section can deform under the pressure. In addition to the deformation cavity of the second main body being deformable, the cavity of the first main body is also deformable under pressure, thereby further increasing the deformation of the seal under stress and improving the maximum deformation degree of the seal, that is, improving the seal's ability to withstand external impacts, and further improving the stability and service life of the seal during use.
[0016] In one possible design, the first main body is elastically deformable and has a slit that extends through one end of the first main body away from the second main body, so that a portion of the cover can extend into the first main body through the slit and be enclosed by the first main body.
[0017] In this solution, since the first main body can deform elastically, when the cover is inserted into the slit, the sidewall of the slit undergoes elastic deformation under the squeezing action of the cover, so that the first main body forms a state of wrapping the cover inserted into the slit with a certain pre-tightening force, thereby reducing the separation of the seal and the cover and improving the stability and reliability of the connection between the cover and the seal.
[0018] In one possible design, the seal further includes at least two protrusions disposed on the side of the second body portion away from the first body portion, and the at least two protrusions extend in mutually distancing directions.
[0019] In this design, the protrusion is located on the side of the second main body away from the first main body, meaning the end of the protrusion forms the sealing contact surface of the seal. With at least two protrusions extending in mutually distancing directions, when the seal is subjected to pressure, the pressure drives the deformation cavity to deform. During deformation, the protrusions consistently press against the sealing interface, providing support. Furthermore, because at least two protrusions extend in mutually distancing directions, they provide a more uniform supporting force to the seal, reducing the possibility of slippage. Moreover, since the protrusions consistently press against the sealing interface in different directions, a multi-layered sealing effect is achieved, further improving the sealing performance of the seal.
[0020] In one possible design, the cross-sectional area of the deformation cavity first increases and then decreases along the height direction of the container lid.
[0021] In this design, the deformation cavity exhibits a cross-sectional profile that first expands and then contracts along the height of the container lid. When the seal is under pressure, the deformation cavity undergoes significant elastic deformation in the expanded section, allowing the cavity wall to extend outward and effectively buffer the pressure. In the contracted section, the seal primarily undergoes compressive deformation, forming an effective support structure that transforms the pressure into sealing pressure at the sealing interface, thereby improving the sealing performance of the interface.
[0022] In one possible design, the seal is made of silicone.
[0023] In this design, silicone is used as the sealing material. Silicone's excellent elasticity allows the seal to recover its shape even after prolonged deformation. During repeated sealing of the container, the seal quickly rebounds after each pressure application, ensuring a good seal over long-term use. Furthermore, silicone's elasticity compensates for gaps, further enhancing the seal. Simultaneously, silicone can withstand high-temperature environments and will not soften during cooking. The elasticity of silicone also allows for a large contact area between the seal and the lid after deformation, effectively increasing friction and preventing slippage, thus ensuring stability and reliability during use.
[0024] Secondly, this application provides a cooking utensil, which includes a container lid and a container body, wherein the container lid is capable of covering the container body, and the container lid is the container lid described above.
[0025] In this solution, the container lid fits snugly onto the container body to form a seal, ensuring the normal use of the cooking appliance.

[0054] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0055] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0056] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0057] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0058] like Figure 1 As shown in the illustration, this application provides a cooking utensil, which includes a container lid and a container body 5, the container lid being able to close onto the container body 5. This cooking utensil can be any of a steamer or a saucepan; the following description uses a steamer as an example.
[0059] For details, please refer to Figure 1 When the cooking appliance is a steamer, the cooking appliance includes a container lid, a steaming rack 3, a steaming grate 4, and a container body 5. The steaming rack 3 and the container body 5 are detachably connected, and the container lid can be placed on the steaming rack 3 or the container body 5.
[0060] This application provides a container lid, such as... Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the container lid includes a lid body 1 and a sealing element 2. The sealing element 2 is installed on the lid body 1. The sealing element 2 includes a deformation cavity 23 and a clamping part 211. The clamping part 211 can clamp and press the lid body 1 to prevent the sealing element 2 from separating from the lid body 1.
[0061] In this embodiment, when the container lid is closed onto the container body 5, the sealing element 2 contacts the container body 5. Under pressure from the lid 1 and the container body 5, the deformation cavity 23 provides sufficient deformation space for the sealing element 2. The sealing element 2 has a large deformable range, enabling it to withstand higher pressure and impact. Furthermore, due to its large deformable range, the sealing element 2 can fill the small gap between the lid 1 and the container body 5 during deformation, further improving its sealing effect. Simultaneously, the clamping part 211 of the sealing element 2 clamps and presses against the lid 1, preventing the lid 1 from detaching from the sealing element 2 and causing sealing failure under external impact, thus ensuring the stability and reliability of the container lid during use.
[0062] In some embodiments, such as Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, the sealing member 2 includes a first main body 21 and a second main body 22 connected to each other along the height direction of the container lid. The first main body 21 includes the aforementioned clamping part 211, and the second main body 22 and the first main body 21 form a deformable cavity 23.
[0063] In this embodiment, by providing a first main body portion 21 and a second main body portion 22 that are interconnected along the height direction of the container lid, the clamping portion 211 and the deformation cavity 23 are distributed along the height direction of the container lid. Therefore, when the container lid is closed onto the container body 5, the clamping portion 211 clamps the lid 1 and transmits the pressure of the lid 1 downwards along the height direction, promoting the deformation of the deformation cavity 23 and thus improving the sealing reliability between the container lid and the container body 5. When the deformation cavity 23 is surrounded by the first main body portion 21 and the second main body portion 22, the deformation cavity 23 is more easily deformed, further improving the sealing reliability between the container lid and the container body 5.
[0064] In some embodiments, such as Figure 2 , Figure 3 As shown, the clamping part 211 includes at least two clamping segments 2111, and there is a gap between the at least two clamping segments 2111. A part of the cover 1 can extend into the gap between the clamping segments 2111, and the clamping segments 2111 extend obliquely toward the direction of the second main body 22.
[0065] In this embodiment, at least two clamping segments 2111 are arranged opposite each other, with a gap between them, and the clamping segments 2111 extend in the direction toward the second main body 22. The clamping segments 2111 extending toward the second main body 22 serve a guiding function. When the seal 2 is installed on the cover 1, since the clamping segments 2111 extend toward the second main body 22, and the direction of movement of the cover 1 is consistent with the direction of the clamping segments 2111, the cover 1 can easily extend through the gap between the clamping segments 2111, thus facilitating the installation of the seal 2 onto the cover 1. Simultaneously, when the cover 1 is withdrawn from between the clamping segments 2111, since the direction of movement is opposite to the extension direction of the clamping segments 2111, the clamping segments 2111 restrict the movement of the cover 1, thereby preventing the cover 1 from detaching from the gap between the clamping segments 2111, and further preventing the seal 2 from detaching from the cover 1, thus improving the reliability of the connection between the cover 1 and the seal 2.
[0066] In some embodiments, the clamping portion 211 may include two or more clamping segments 2111, and the two or more clamping segments 2111 are spaced apart, with the ends of each clamping segment 2111 forming the aforementioned gap.
[0067] Furthermore, the clamping part 211 can be a plurality of opposing clamping sections 2111 arranged along the extension direction of the cover 1. By using a plurality of opposing clamping sections 2111, the contact area between the cover 1 and the clamping sections 2111 is further increased, the resistance that the cover 1 needs to overcome when it exits the clamping sections 2111 is increased, and the reliability of the connection between the seal 2 and the cover 1 is ensured.
[0068] In some embodiments, such as Figure 2 , Figure 3 As shown, the angle between the clamping section 2111 and the height of the container lid is α, which satisfies: 30°≤α≤45°. For example, α can be: 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°.
[0069] When α is too small, a sharp angle is formed at the connection between the clamping section 2111 and the first main body 21. When the seal 2 is under force, stress concentration is likely to occur, leading to breakage at the connection between the clamping section 2111 and the first main body 21, affecting the service life of the seal 2. When α is too large, the clamping section 2111 is too gentle, and the guiding effect when the cover 1 is inserted is lacking. Moreover, after the cover 1 is inserted, the clamping section 2111 has little restraining effect on both sides of the cover 1, and the cover 1 can generate a large amount of shaking between the clamping sections 2111, which is not conducive to the stability of operation. When the cover 1 is withdrawn from between the clamping sections 2111, since the clamping section 2111 and the withdrawal direction of the cover 1 are almost parallel, the friction effect between the cover 1 and the clamping section 2111 is poor, and loosening is likely to occur. In this embodiment, 30°≤α≤45° ensures the service life of the seal 2. During the process of the cover 1 extending along the direction of the second main body 22, the inclined clamping section 2111 provides a reliable guiding effect for the cover 1, reduces assembly resistance, and effectively abuts against both sides of the cover 1 after the cover 1 is inserted, maintaining the stability of the cover 1. When the cover 1 is withdrawn from between the clamping sections 2111, the downwardly inclined clamping section 2111 can restrict the cover 1 from separating from the seal 2, ensuring the stability of the connection between the cover 1 and the seal 2.
[0070] In some embodiments, such as Figure 2 , Figure 3 As shown, the first main body 21 has a cavity 212, and a part of the cover 1 can extend into the cavity 212 through the gap between the clamping sections 2111.
[0071] In this embodiment, when the container body 5 is closed to the container lid and the seal 2 is subjected to pressure, the clamping section 2111 can deform under the pressure. In addition to the deformation cavity 23 of the second main body 22 being deformable under pressure, the cavity 212 of the first main body 21 can also be deformed, thereby further increasing the deformation of the seal 2 under force and improving the maximum deformation degree of the seal 2, that is, improving the seal 2's ability to withstand external impacts and further improving the stability and service life of the seal 2 during use.
[0072] In other embodiments, such as Figure 5 , Figure 6 As shown, the first main body 21 is elastically deformable. The first main body 21 is provided with a slit 2112. The slit 2112 passes through the end of the first main body 21 away from the second main body 22. A part of the cover 1 extends into the first main body 21 through the slit 2112 and is wrapped by the first main body 21.
[0073] In this embodiment, since the first main body 21 can elastically deform, when the cover 1 extends into the slit 2112, the sidewall of the slit 2112 undergoes elastic deformation under the squeezing action of the cover 1, so that the first main body 21 forms a state of wrapping the cover 1 extending into the slit 2112 with a certain pre-tightening force, thereby reducing the separation of the seal 2 from the cover 1 and improving the stability and reliability of the connection between the cover 1 and the seal 2.
[0074] In some embodiments, the sidewall of the slit 2112 may be provided with a protrusion, thereby further increasing the friction between the first main body 21 and the cover 1, and further reducing the risk of the cover 1 detaching from the seal 2.
[0075] In the above embodiments, as Figure 3 , Figure 6 As shown, the cross-sectional area of the deformation cavity 23 first increases and then decreases along the height direction of the container lid.
[0076] In this embodiment, the deformation cavity 23 exhibits a cross-sectional profile that first expands and then contracts along the height direction of the container lid. When the seal 2 is under pressure, the deformation cavity 23 undergoes significant elastic deformation in the expanded cross-sectional area, allowing the cavity wall to extend outward and providing a good buffering effect against pressure. In the reduced cross-sectional area, the seal 2 primarily undergoes compressive deformation, forming an effective support structure that transforms the pressure into sealing pressure at the sealing interface, thereby improving the sealing performance of the sealing interface.
[0077] In the above embodiments, as Figure 3 , Figure 6 As shown, the second main body 22 includes at least two protrusions 221, which are disposed on the side of the second main body 22 away from the first main body 21, and the at least two protrusions 221 extend in a direction away from each other.
[0078] In this embodiment, the protrusion 221 is located on the side of the second main body 22 away from the first main body 21, that is, the end of the protrusion 221 forms the sealing contact surface of the seal 2. With at least two protrusions 221 extending in mutually distancing directions, when the seal 2 is subjected to pressure, the pressure drives the deformation cavity 23 to deform. During the deformation process, the protrusions 221 consistently press against the sealing interface, forming a support. Furthermore, since at least two protrusions 221 extend in mutually distancing directions, they can provide a more uniform supporting force to the seal 2, reducing the possibility of slippage. Moreover, because the protrusions 221 consistently press against the sealing interface in different directions, a multi-layered sealing effect is formed, further improving the sealing effect of the seal 2.
[0079] In all the above embodiments, the material of the sealing element 2 is silicone. Using silicone as the material for the sealing element 2 allows it to recover its shape even after prolonged deformation due to its excellent elasticity. During the repeated sealing of the container lid onto the container body 5, the sealing element 2 quickly rebounds after each pressure application, ensuring a good sealing effect during long-term use. Furthermore, the elasticity of silicone compensates for sealing gaps, further improving the sealing effect. Simultaneously, because silicone can withstand high-temperature working environments, it will not soften during cooking. The elasticity of silicone also allows the sealing element 2 to form a large contact area with the lid 1 after deformation, effectively increasing the friction between the sealing element 2 and the lid 1, preventing slippage between the lid 1 and the sealing element 2, and ensuring stability and reliability during use.
[0080] In some embodiments, such as Figure 1 , Figure 5 As shown, the cover 1 is provided with an exhaust port 11 and a pressure limiting valve 12. The pressure limiting valve 12 is used to control the opening and closing of the exhaust port 11.
[0081] In this embodiment, since the cooking appliance will generate a small amount of steam in the early stage of heating and will be discharged through the vent 11, by setting a pressure limiting valve 12 at the vent 11, it can be ensured that the small amount of steam generated in the early stage of heating will not escape, thereby improving the heating efficiency in the early stage of heating. When the pressure of the cooking appliance is too high, the internal steam can be discharged through the vent 11 and the pressure limiting valve 12, so that there is still sufficient pressure inside the cooking appliance while ensuring safety, thereby improving the working efficiency of the cooking appliance.
[0082] In some embodiments, such as Figure 1 , Figure 5 As shown, the container lid has a stepped portion 13, which protrudes outward along the radial direction of the container lid. The cooking utensil includes a handle 31, which has a movable portion 311 that is capable of moving radially along the cooking utensil.
[0083] refer to Figure 1 When the movable part 311 is in the first state, it abuts against the step part 13 along the height direction of the cooking appliance; (Reference) Figure 5 When the moving part 311 is in the second state, the moving part 311 and the step part 13 are released from contact along the height direction of the cooking appliance.
[0084] In this embodiment, the movable part 311 on the handle 31 abuts against the step part 13, restricting the displacement of the cover 1 along the height direction of the cooking appliance, preventing the cover 1 from being accidentally opened during cooking, and the movable part 311 can provide a pressing force to the step part 13, so that the cover 1 is tightly connected to the steamer rack 3, further improving the sealing of the cooking appliance.
