Description

Technical Field

[0001] This utility model relates to the field of cooking container technology, and in particular to a container lid. Background Technology

[0002] Cooking containers such as soup pots typically have vent pipes on their lids to release steam from the container during cooking, preventing excessive steam pressure from causing the lid to pop open and posing a safety hazard. In related technologies, the lids can also have anti-clogging covers, located at one end of the vent pipe's air inlet. These covers prevent food from entering the vent pipe during steam release, reducing the risk of food being expelled with the steam. However, in these cases, the anti-clogging covers are usually directly installed on the vent pipe. Installing or removing the anti-clogging covers can easily damage them, causing them to fail to keep food out and resulting in food spraying out of the vent pipe during cooking. Utility Model Content

[0003] This application provides a container cover to solve the problem of food spraying out of the exhaust pipe during cooking due to damage to the anti-clogging cover during disassembly and installation.

[0004] To address the aforementioned problems, this application provides a container cap, comprising: a cap body; an exhaust pipe, wherein the exhaust pipe is installed on the cap body and includes a first pipe segment and a second pipe segment; an anti-clogging cover, the anti-clogging cover having a first cavity, the anti-clogging cover being located on one side of the cap body along the thickness direction of the container cap, and the second pipe segment extending into the first cavity; the container cap further comprising a locking member, the locking member being detachably connected to the second pipe segment, so that the anti-clogging cover is clamped between the cap body and the locking member along the thickness direction of the container cap.

[0005] In this embodiment, the locking member is detachably connected to the second pipe segment. When the second pipe segment extends into the first cavity of the anti-clogging cover, the locking member connects to the second pipe segment, allowing the anti-clogging cover to be clamped between the cover and the locking member. The locking member can also be disconnected from the second pipe segment, at which point the user can remove the anti-clogging cover from the container cover.

[0006] Therefore, when the user installs the anti-clogging cover, the second section of the exhaust pipe is positioned within the first cavity of the anti-clogging cover. The locking member is connected to the second section. After connection, the anti-clogging cover is clamped between the locking member and the lid along the thickness direction of the container lid. At this time, at least a portion of the second section is located within the first cavity of the anti-clogging cover, ensuring the exhaust pipe inlet is within the first cavity. This prevents food from being ejected from the exhaust pipe with steam during cooking, improving the user experience. When the user disassembles the anti-clogging cover, simply disconnecting the locking member from the second section of the exhaust pipe removes the cover. As can be seen from the above installation and disassembly process, in this embodiment, the locking member is detachably connected to the second section, thus clamping the anti-clogging cover between the lid and the locking member. This eliminates the need for the anti-clogging cover to be directly fixed to the exhaust pipe, preventing damage to the anti-clogging cover during installation or disassembly and extending its service life.

[0007] In one embodiment, the locking member includes a limiting portion located on the side of the anti-blocking cover opposite to the cover body, so that the cover body and the limiting portion clamp the anti-blocking cover.

[0008] In this design, when the locking element is connected to the second pipe section, the top wall of the anti-clogging cover abuts against the cover, and the bottom wall of the anti-clogging cover abuts against the limiting part of the locking element. The limiting part applies a force along the thickness direction of the container cover towards the cover, allowing the anti-clogging cover to fit tightly against one side of the cover. This enables the locking element and the cover to jointly clamp the anti-clogging cover. Therefore, in this embodiment, the limiting part of the locking element and the cover can jointly clamp the anti-clogging cover, improving the stability of the anti-clogging cover installed on the container cover.

[0009] In one specific embodiment, the locking member further includes a connecting portion connected to the limiting portion, the connecting portion extending into the first cavity and detachably connected to the second pipe segment, and the limiting portion being a step extending radially outward relative to the connecting portion.

[0010] In this design, the connecting part of the locking component is detachably connected to the second pipe section within the first cavity. This increases the mating area between the locking component and the second pipe section, thereby improving the connection reliability between the locking component and the connecting part, and consequently enhancing the installation reliability of the anti-clogging cover. Furthermore, the stepped limiting part provides a larger contact area between the limiting part and the anti-clogging cover, further improving the installation reliability of the anti-clogging cover.

[0011] In one specific embodiment, along the thickness direction of the container lid, there is a gap t between the connecting part and the lid body, where 0.5mm≤t≤1mm.

[0012] In this design, when 0.5mm≤t≤1mm, the gap t between the connecting part and the cover is moderate, which can prevent the locking part from damaging the cover during installation and also make the installation reliability of the anti-blocking cover high.

[0013] In one specific embodiment, the connecting part is threadedly connected to the second pipe section; the end of the limiting part opposite to the anti-blocking cover is provided with a mating groove, which is used to rotate the locking member.

[0014] In this embodiment, the user can use a tool to engage with the mating groove, thereby rotating the locking member with the tool to facilitate the connection or disconnection of the locking member and the second pipe section on the outside of the first cavity of the anti-blocking cover.

[0015] In one specific embodiment, the anti-blocking cover is provided with at least one first vent hole, the connecting part has a second cavity, the second pipe section extends into the second cavity and is detachably connected to the connecting part; there is a vent space between the second pipe section and the bottom wall of the second cavity, the side wall of the vent space is provided with at least one second vent hole, the vent pipe has a vent channel, and the vent channel communicates with the first cavity through the second vent hole and the vent space.

[0016] In this design, when the container lid is closed onto the container body, steam inside the container enters the first chamber through the first vent of the anti-clogging cover, and then enters the exhaust space of the second chamber through the second vent of the connecting part. From there, it enters the exhaust pipe through the inlet and exits to the outside through the outlet of the exhaust pipe, thus achieving venting. During the venting process, the steam can accumulate and be buffered in the first chamber before entering the connecting part, and it can also accumulate and be buffered in the exhaust space, thereby reducing the risk of splashing when the steam is discharged through the exhaust pipe and improving the safety of the container lid. Furthermore, when some food enters the anti-clogging cover with the steam, the first chamber of the anti-clogging cover and the exhaust space of the connecting part can collect the food, preventing it from being ejected from the exhaust pipe with the steam.

[0017] In one specific embodiment, the first vent hole includes at least one first through hole and at least one second through hole, the first through hole being disposed on the side wall of the anti-clogging cover and the second through hole being disposed on the bottom wall of the anti-clogging cover.

[0018] In this design, when the container lid is closed on the container body, the steam inside the container during cooking can enter the first cavity through at least one first through hole and at least one second through hole, thereby improving the exhaust efficiency of the exhaust pipe and further reducing the risk of excessive pressure inside the container.

[0019] In one specific embodiment, the sum of the flow cross-sectional areas of each of the second exhaust holes is S1, and the flow cross-sectional area of ​​the exhaust channel is S2, where S1 > S2.

[0020] In this scheme, the sum of the flow cross-sectional areas of each second exhaust hole in the connection part is greater than the flow cross-sectional area of ​​the exhaust channel of the exhaust pipe, thereby increasing the steam flow rate into the exhaust space of the connection part through the second exhaust hole, resulting in a larger amount of steam in the exhaust space, which in turn promotes the steam in the exhaust space to enter the exhaust channel and improves the exhaust efficiency of the exhaust pipe.

[0021] In one specific embodiment, the diameter of the second exhaust hole is D1, the diameter of the exhaust channel is D2, and 1 < D2 / D1 ≤ 2.5.

[0022] In this design, the diameter of the exhaust channel is in a suitable ratio to the diameter of the second exhaust hole, which enables the exhaust pipe to have high exhaust efficiency and reduces the risk of food splashing out with the steam.

[0023] In one specific embodiment, the exhaust pipe further includes a first pipe section, which is integrally formed with the second pipe section. The cover has a mounting hole, through which the second pipe section extends into the first cavity, and the bottom wall of the first pipe section abuts against the cover.

[0024] In this design, the bottom wall of the first pipe section abuts against the cover, and the cover can restrict the movement of the first pipe section along the thickness direction of the container cover, thereby restricting the relative movement of the exhaust pipe relative to the cover along the thickness direction of the container cover, so that the exhaust pipe is connected to the cover. When the locking member is connected to the second pipe section of the exhaust pipe, it restricts the relative movement of the locking member and the cover along the thickness direction of the container cover, thereby clamping the anti-clogging cover between the cover and the locking member along the thickness direction of the container cover, improving the installation reliability of the anti-clogging cover.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] This application provides a container lid, such as... Figure 2 As shown, the container lid includes a lid body 1, an exhaust pipe 2, and an anti-clogging cover 3.

[0052] Among them, such as Figure 1 As shown, the exhaust pipe 2 includes a first pipe section 21 and a second pipe section 22. In one embodiment, the first pipe section 21 and the second pipe section 22 of the exhaust pipe 2 are an integral structure. The second pipe section 22 passes through the cover 1, and a part of the second pipe section 22 is located inside the cover 1, while the other part of the second pipe section 22 extends to the outside of the cover 1, so that the part of the second pipe section 22 extending out of the cover 1 and the first pipe section 21 are located on both sides of the cover 1. In another embodiment, the first pipe section 21 and the second pipe section 22 of the exhaust pipe 2 are separate structures, and the first pipe section 21 and the second pipe section 22 are located on both sides of the cover 1 along the thickness direction, and are both fixedly connected to the cover 1. That is, there is a cover 1 between the first pipe section 21 and the second pipe section 22, and the cover 1 is provided with a through hole, so that the first pipe section and the second pipe section 22 are connected through the through hole.

[0053] like Figure 1 and Figure 2 As shown, along the thickness direction of the container cap, the anti-clogging cover 3 is located on the side of the cap 1 opposite to the first pipe section 21. The anti-clogging cover 3 has a first cavity 32, and at least a portion of the structure of the second pipe section 22 of the exhaust pipe 2 is located within the first cavity 32. That is, when the exhaust pipe 2 includes an integrally formed first pipe section 21 and a second pipe section 22, a portion of the structure of the second pipe section 22 is located within the first cavity 32; when the exhaust pipe 2 includes a separately formed first pipe section 21 and a second pipe section 22, the second pipe section 22 is located within the first cavity 32.

[0054] In this embodiment, the exhaust pipe 2 of the container lid has an inlet and an outlet, with the inlet located on the second pipe section 22 and the outlet located on the first pipe section 21. When the container lid is closed on the container body, steam enters the exhaust pipe 2 through the inlet of the second pipe section 22 and exits from the outlet of the first pipe section 21. This exhaust pipe 2 is used to discharge steam during the cooking process, preventing excessive steam pressure inside the container from causing the container lid to lift. Furthermore, when at least a portion of the second pipe section 22 is located within the first cavity 32 of the anti-clogging cover 3, the inlet of the exhaust pipe 2 is located within the first cavity 21, thereby preventing food from being ejected from the exhaust pipe 2 along with the steam during cooking, improving the user experience.

[0055] like Figure 1 and Figure 2 As shown, the container lid also includes a locking element 4, which can be detachably connected to the second pipe section 22, so that the anti-blocking cover 3 is clamped between the lid body 1 and the locking element 4.

[0056] In this embodiment, when installing the anti-clogging cover 3, it is only necessary to place the anti-clogging cover 3 between the locking member 4 and the cover 1, and connect the locking member 4 to the exhaust pipe 2 installed on the cover 1. After connection, the anti-clogging cover 3 is clamped between the locking member 4 and the cover 1 along the thickness direction of the container cover. When removing the anti-clogging cover 3, it is only necessary to disconnect the locking member 4 from the second pipe section 22 of the exhaust pipe 2 to remove the anti-clogging cover 3. As can be seen from the above-described installation and removal process, in this embodiment, the anti-clogging cover 3 is clamped between the cover 1 and the locking member 4 by detachably connecting the locking member 4 and the second pipe section 22, so that the anti-clogging cover 3 does not need to be directly fixed to the exhaust pipe 2, preventing damage to the anti-clogging cover 3 during installation or removal, and improving the service life of the anti-clogging cover 3.

[0057] In one specific embodiment, such as Figure 1 and 2 As shown, the locking member 4 includes a limiting part 41, which is located on the side of the anti-blocking cover 3 away from the cover body 1. When the locking member 4 is connected to the second pipe section 22 of the exhaust pipe 2, the cover body 1 and the limiting part 41 clamp the anti-blocking cover 3.

[0058] In this embodiment, when the locking member 4 is connected to the second pipe section 22, the top wall of the anti-clogging cover 3 abuts against the cover 1, and the bottom wall of the anti-clogging cover 3 abuts against the limiting part 41 of the locking member 4. The limiting part 41 can apply a force to the anti-clogging cover 3 along the thickness direction of the container cover towards the cover 1, so that the anti-clogging cover 3 can fit tightly against one side of the cover 1, and the locking member 4 and the cover 1 can jointly clamp the anti-clogging cover 3. Therefore, in this embodiment, the limiting part 41 of the locking member 4 can jointly clamp the anti-clogging cover 3 with the cover 1, improving the stability of the anti-clogging cover 3 installed on the container cover.

[0059] In one specific embodiment, such as Figure 1 and 2 As shown, the locking member 4 also includes a connecting part 42 connected to the limiting part 41. The connecting part 42 extends into the first cavity 32 and is detachably connected to the second pipe section 22. The limiting part 41 is a step that extends radially outward relative to the connecting part 42.

[0060] In this embodiment, the connecting portion 42 of the locking member 4 is detachably connected to the second pipe section 22 within the first cavity 32, which increases the mating area between the locking member 4 and the second pipe section 22, thereby improving the connection reliability between the locking member 4 and the connecting portion 42 and the second pipe section 22, and further improving the installation reliability of the anti-clogging cover 3. In addition, the stepped limiting portion 41 provides a larger contact area between the limiting portion 41 and the anti-clogging cover 3, thereby further improving the installation reliability of the anti-clogging cover 3.

[0061] In one specific embodiment, such as Figure 1As shown, along the thickness direction of the container lid, there is a gap t between the connecting part 42 and the lid body 1, where 0.5mm ≤ t ≤ 1mm. For example, the gap t can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc.

[0062] When the locking member 4 is connected to the second pipe segment 22, there is a gap t between the connecting part 42 and the cover 1. When this gap t is too small, there is a risk that the connecting part 42 may interfere with the cover 1 during the connection process, causing damage to the cover 1. When this gap t is too large, after the locking member 4 and the second pipe segment 22 are connected, the mating area between the connecting part 42 of the locking member 4 and the second pipe segment 22 decreases, resulting in a decrease in the reliability of the connection between the locking member 4 and the second pipe segment 22, affecting the installation reliability of the anti-blocking cover 3. In this embodiment, when 0.5mm≤t≤1mm, the gap t between the connecting part 42 and the cover 1 is moderate, which can prevent the locking member 4 from damaging the cover 1 during installation and also ensures a high installation reliability of the anti-blocking cover 3.

[0063] In one specific embodiment, such as Figure 1 As shown, the connecting part 42 is threadedly connected to the second pipe section 22; the end of the limiting part 41 away from the anti-blocking cover 3 is provided with a mating groove 411, which is used to rotate the locking member 4. The shape of the mating groove 411 can be cross-shaped or other shapes, and this application does not limit the shape of the mating groove 411.

[0064] In this embodiment, one of the connecting part 42 and the second pipe section 22 is provided with an internal thread, and the other is provided with an external thread, thereby enabling the connecting part 42 and the second pipe section 22 to be threadedly connected. A mating groove 411 is provided at the end of the limiting part 41 facing away from the anti-blocking cover 3. When assembling or disassembling the anti-blocking cover 3, the mating groove 411 is used to rotate the locking member 4. Specifically, the user can use a tool to engage with the mating groove 411, thereby rotating the locking member 4 by the tool, which facilitates the connection or disconnection of the locking member 4 and the second pipe section 22 on the outside of the first cavity 32 of the anti-blocking cover 3.

[0065] In other embodiments, the detachable connection between the connecting part 42 and the second pipe segment 22 can also be achieved in other ways, such as snap-fit, that is, the connecting part 42 and the second pipe segment 22 are provided with a mutually compatible snap-fit ​​structure, and the connecting part 42 can be configured as a structure that can be elastically deformed, thereby facilitating the disassembly of the connecting part 42 and the second pipe segment 22 so that the anti-blocking cover 3 can be disassembled.

[0066] In the above embodiments, as Figure 2As shown, the anti-blocking cover 3 is provided with at least one first vent 31, and the connecting part 42 is provided with at least one second vent 422. The connecting part 42 has a second cavity 421, and a second pipe section 22 extends into the second cavity 421 and is detachably connected to the connecting part 42. There is a venting space between the second pipe section 22 and the bottom wall of the second cavity 421, and the second vent 422 is provided on the side wall of the venting space. The exhaust pipe 2 is connected to the external environment through the second vent 422, the first cavity 421, the first vent 31, and the second cavity 421.

[0067] In this embodiment, when the second pipe segment 22 extends into the second cavity 421 of the connecting part 42 and is detachably connected to the connecting part 42, the connection reliability between the second pipe segment 22 and the connecting part 42 is high. When the second pipe segment 22 is threadedly connected to the connecting part 42, the outer wall of the second pipe segment 22 is provided with external threads, and the inner wall of the second cavity 421 is provided with internal threads.

[0068] When the container lid is closed on the container body, the steam inside the container enters the first cavity 421 through the first vent 31 of the anti-clogging cover 3, and then enters the exhaust space of the second cavity 421 through the second vent 422 of the connecting part 42. It then enters the exhaust pipe 2 through the inlet and exits to the outside through the outlet of the exhaust pipe 2, thus achieving venting. During the venting process, the steam can accumulate and be buffered within the first cavity 421 before entering the connecting part 42. The steam can also accumulate and be buffered within the exhaust space, thereby reducing the risk of splashing when the steam is discharged through the exhaust pipe 2 and improving the safety of the container lid. Furthermore, when some food enters the anti-clogging cover 3 with the steam, the first cavity of the anti-clogging cover 3 and the exhaust space of the connecting part 42 can collect the food, preventing it from being ejected from the exhaust pipe 2 with the steam.

[0069] In one possible embodiment, such as Figure 2 As shown, the first vent 31 includes at least one first through hole 311 and at least one second through hole 312, wherein at least one first through hole 311 is disposed on the side wall of the anti-clogging cover 3, and at least one second through hole 312 is disposed on the bottom wall of the anti-clogging cover 3.

[0070] In this embodiment, the side wall and bottom wall of the anti-blocking cover 3 are respectively provided with a first through hole 311 and a second through hole 312, and both the first through hole 311 and the second through hole 312 are connected to the first cavity 32 of the anti-blocking cover 3. When the container lid is closed on the container body, the steam in the container body during the cooking process can enter the first cavity 32 through at least one first through hole 311 and at least one second through hole 312, thereby improving the exhaust efficiency of the exhaust pipe 2 and further reducing the risk of excessive pressure in the container body.

[0071] In such Figure 2In the illustrated embodiment, the second through hole 312 can be a circular hole, and the first through hole 311 can be an elongated hole, meaning that the flow cross-sectional area of ​​the first through hole 311 is larger, thereby increasing the flow rate of steam entering the first cavity 32 and further promoting exhaust. In other embodiments, the first through hole 311 and the second through hole 312 can also be other shapes, such as triangular, square, irregular, etc.

[0072] In one possible embodiment, such as Figure 2 As shown, the exhaust pipe 2 has an exhaust channel 23, and the sum of the flow cross-sectional areas of the plurality of second exhaust holes 422 is S1, the flow cross-sectional area of ​​the exhaust channel 23 is S2, and S1 > S2.

[0073] When the container lid is closed on the container body, the sum of the flow cross-sectional areas of each of the second vent holes 422 of the connecting part 42 is greater than the flow cross-sectional area of ​​the exhaust channel 23 of the exhaust pipe 2. This results in a larger steam flow rate entering the exhaust space of the connecting part 42 through the second vent holes 422, resulting in a larger amount of steam in the exhaust space. This, in turn, promotes the steam in the exhaust space to enter the exhaust channel 23, thereby improving the exhaust efficiency of the exhaust pipe 2.

[0074] In one possible embodiment, the diameter of the second exhaust port 422 is D1, the diameter of the exhaust channel 23 is D2, and 1 < D2 / D1 ≤ 2.5. For example, D2 / D1 can be 1.1, 1.3, 1.5, 1.7, 1.9, 2, 2.1, 2.4, 2.5, etc.

[0075] When D2 / D1 is too small, the diameter of the exhaust channel 23 is close to the diameter of the second exhaust hole 422, which means the flow cross-sectional area of ​​the exhaust channel 23 may be smaller than the flow cross-sectional area of ​​the multiple second exhaust holes 422. Steam in the exhaust space of the connecting part 42 cannot quickly enter the exhaust channel 23, resulting in low exhaust efficiency of the exhaust pipe 2. Furthermore, if the flow cross-sectional area of ​​the second exhaust hole 422 is too large, there is a risk that food in the first cavity 32 will enter the exhaust space and then the exhaust pipe 2 along with the steam through the second exhaust hole 422, potentially causing food splashing. When D2 / D1 is too large, the diameter of the exhaust channel 23 differs too much from the diameter of the second exhaust hole 422. With a fixed diameter of the exhaust channel 23, the diameter of the second exhaust hole 422 becomes too small, preventing steam in the first cavity 32 from quickly entering the exhaust space and affecting exhaust efficiency. In this embodiment, when 1 < D2 / D1 ≤ 2.5, the diameter of the exhaust channel 23 is moderately equal to the diameter of the second exhaust hole 422, which can make the exhaust efficiency of the exhaust pipe 2 high and reduce the risk of food splashing when it is discharged with steam.

[0076] In one specific embodiment, such as Figure 1As shown, the cover 1 has a mounting hole 11, the second pipe section 22 extends into the first cavity 32 through the mounting hole 11, and the bottom wall of the first pipe section 21 abuts against the cover 1.

[0077] In this embodiment, the bottom wall of the first pipe section 21 abuts against the cover 1. The cover 1 can restrict the movement of the first pipe section 21 along the thickness direction of the container cover, thereby restricting the relative movement of the exhaust pipe 2 relative to the cover 1 along the thickness direction of the container cover, so that the exhaust pipe 2 is connected to the cover 1. When the locking member 4 is connected to the second pipe section 22 of the exhaust pipe 2, it restricts the relative movement of the locking member 4 and the cover 1 along the thickness direction of the container cover, thereby clamping the anti-blocking cover 3 between the cover 1 and the locking member 4 along the thickness direction of the container cover, improving the installation reliability of the anti-blocking cover 3.

Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application.
