Description

Technical Field

[0001] This utility model relates to the field of food storage containers, specifically to a lid and a food preservation box. Background Technology

[0002] Currently, safes on the market are generally developing in two directions. One type aims for a good seal, using a four-sided folding latch on the lid, but this is relatively cumbersome to use. The other type aims for easy opening, pressing the lid into the box body through a sealing ring. The negative pressure inside the box forces the lid to close, but when the temperature inside the box is high, the air pressure can easily push the lid off, failing to achieve a truly airtight seal.

[0003] Therefore, there is an urgent need to develop a food storage container that is both easy to open and can achieve a good sealing effect. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a lid and a food storage box that are easy to open and have a good sealing effect.

[0005] A first aspect of this utility model provides a box lid for covering the opening of a box. The box lid includes: a lid body with a vent hole; a first buckle, which is flip-mounted on the lid body and covers the vent hole, and is used to fasten the first end of the lid body to one side of the box body; and a second buckle, which is located at the second end of the lid body opposite to the first end and is used to fasten the second end to the other side of the box body, and is capable of being released from the box body as the lid body or the first buckle is flipped.

[0006] The lid provided in this embodiment has a first latch and a second latch at opposite ends of the lid body. These latches engage with the box body, ensuring a secure connection between the lid and the box body and preventing the lid from being lifted by hot air inside the box, thus maintaining a good seal. Furthermore, when opening the lid, the first latch can be flipped with one hand to release it from the box body. The second latch then automatically releases itself as the first latch or the lid body flips, allowing for easy one-handed opening. Moreover, as the first latch flips upwards, the vent is opened, allowing for pressure exchange between the inside and outside of the food storage container without needing to open the vent cap, further simplifying the opening process and greatly enhancing user convenience.

[0007] Furthermore, in some embodiments, the second buckle is fixedly disposed at the second end of the cover body.

[0008] In these embodiments, the second latch is fixed relative to the cover body, so that the second latch can be released from the box body as the cover body is flipped, without the need to fold the second latch separately to unlock or fasten it, which is conducive to one-handed operation during the opening and closing of the cover and is convenient to operate.

[0009] Furthermore, in some embodiments, the second latch is movably disposed on the cover body and linked with the first latch. When the first latch is flipped to its latching position, it can drive the second latch to move to the latching position of the second latch, and when it is flipped to its unlocking position, it can drive the second latch to move to the unlocking position of the second latch.

[0010] In these embodiments, the second latch and the first latch are linked, which makes it convenient to operate the first latch with one hand, and allows the first latch and the second latch to simultaneously release from the latched state with the box body, or simultaneously latch the box body, making the opening and closing of the cover convenient and quick.

[0011] Furthermore, in some embodiments, the cover body is provided with a guide structure for guiding the second buckle to move laterally on the cover body in a direction close to or away from the second end when the first buckle is flipped.

[0012] In these embodiments, the second latch moves laterally, minimizing the space it occupies. Furthermore, moving the second latch away from the second end ensures it is away from the box body, thus ensuring it is released from the box. Moving the second latch closer to the second end facilitates its engagement with the box body. Additionally, using a guide structure to restrict the movement path of the second latch helps ensure accurate positioning.

[0013] Furthermore, in some embodiments, one of the adjacent ends of the first buckle and the second buckle is provided with a hook, and the other of the adjacent ends of the first buckle and the second buckle is provided with a groove. The hook extends into the groove, and the first buckle and the second buckle are linked together through the mutual cooperation of the hook and the groove.

[0014] In these embodiments, during the flipping process of the first buckle, the movement of the second buckle is achieved through the linkage of the buckle groove and the buckle hook. The structure is simple, easy to process, and the transmission is stable and reliable.

[0015] Furthermore, in some embodiments, the hook is disposed on the second buckle, and the slot is disposed on the first buckle. When the first buckle flips from the engaged position to the unlocked position, the slot moves downward and disengages from the hook. The slot sidewall near the first end of the slot presses against the hook, pushing the second buckle away from the second end, thereby unlocking the second buckle from the box. When the first buckle flips from the unlocked position to the engaged position, the slot sidewall near the second end of the slot presses against the hook, pushing the second buckle closer to the second end and engaging with the box.

[0016] In these embodiments, the transverse hook is moved by the slot moving closer to or further away from the side wall of the first end, thereby pushing the first buckle away from or closer to the second end of the cover body. The linkage structure is simple and the transmission is stable and reliable.

[0017] Furthermore, in some embodiments, the lid body is provided with an interconnected recess, a first notch, and a second notch. The first notch extends from the recess to a first end of the lid body, and the second notch extends from the recess to a second end of the lid body. A portion of the first buckle extends into the recess and is rotatably connected to the lid body, while the other portion extends into the first notch and engages with one side of the box body at the first notch. A portion of the second buckle extends into the recess, while the other portion extends into the second notch and engages with the other side of the box body at the second notch.

[0018] In these embodiments, the first and second latches are partially concealed within the recessed groove, and both extend into the first and second notches, reducing their overall height and minimizing their space occupation. Furthermore, the first latch engages with the box body at the first notch, and the second latch engages with the box body at the second notch, making engagement convenient.

[0019] Furthermore, in some embodiments, when the first and second latches are engaged, the upper surfaces of the cover body, the first latch, and the second latch are flush, the outer peripheral edge of the first latch is flush with the first end edge of the cover body, and the outer peripheral edge of the second latch is flush with the second end edge of the cover body; and / or a guide structure is provided on the inner wall of the recess. The lid has a good aesthetic appearance.

[0020] Furthermore, in some embodiments, a sealing plug is provided on the lower surface of the first buckle corresponding to the position of the vent hole, and the sealing plug is used to block the vent hole. By sealing the vent hole with the sealing plug, heat loss from the box can be prevented, and the misflow of air between the inside and outside of the box can be prevented, thereby improving the sealing effect of the food storage box.

[0021] Furthermore, in some embodiments, the lower surface of the cover body is provided with a downwardly extending connecting rib, and a sealing ring is sleeved on the outer periphery of the connecting rib. The sealing ring is used to extend into the box body and abut against the inner sidewall of the box body.

[0022] In these embodiments, when the lid is placed on the box body, the sealing ring can be pressed into the box body and abut against the inner side wall of the box body. This facilitates the discharge of some gas inside the box through the vent during the lid-closing process, thereby creating a certain negative pressure inside the box to hold the lid in place, which can improve the sealing performance of the food storage box.

[0023] A second aspect of this utility model provides a food storage box, which includes: a box body; a box lid as described in any of the above embodiments, wherein a first buckle and a second buckle are fastened to opposite sides of the box body.

[0024] The food storage container provided in this embodiment has the lid of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be repeated here.

[0025] Other aspects and / or advantages of the present invention will be set forth in part in the description which follows, and others will be clear from the description or may be learned by practice of the present invention. Attached Figure Description

[0036] The following will combine Figures 1 to 11 This invention introduces a lid and a food storage container provided by embodiments of the present invention.

[0037] like Figure 1 and Figure 8 As shown, a first aspect of this utility model provides a box lid for closing the opening of a box body. The box lid includes: a lid body 100, on which a vent hole 102 is provided; a first buckle 110, which is flip-mounted on the lid body 100 and covers the vent hole 102, and is used to fasten the first end of the lid body 100 to one side of the box body 200; and a second buckle 120, which is disposed at the second end of the lid body 100 opposite to the first end, and is used to fasten the second end of the box body 200 to the other side of the box body 200. The second buckle 120 can contact and fasten with the box body 200 as the lid body 100 or the first buckle 110 is flipped.

[0038] The lid provided in this embodiment has a first latch 110 and a second latch 120 at opposite ends of the lid body 100. The first latch 110 and the second latch 120 engage with the box body 200, ensuring a secure connection between the lid and the box body 200. This prevents the lid from being lifted by hot air inside the box body 200, thus maintaining a good seal. Furthermore, when opening the lid, the first latch 110 can be flipped with one hand to release it from the box body 200. The second latch 120 then automatically releases itself from the box body 200 as the first latch 110 or the lid body 100 is flipped, allowing for easy one-handed opening. Moreover, as the first latch 110 flips upwards, the vent 102 opens, allowing for pressure exchange between the inside and outside of the food storage container. This eliminates the need to open the vent cap, further simplifying the opening process and greatly enhancing user convenience.

[0039] Furthermore, the second latch 120 can be fixedly disposed at the second end of the lid body 100, with the second latch 120 being relatively fixed to the lid body 100. This allows the second latch 120 to release its engagement with the box body 200 as the lid body 100 is flipped, or to engage with the box body 200 as the lid body 100 is flipped. There is no need to separately fold the second latch 120 to unlock it, which facilitates one-handed operation during lid opening and closing, making operation convenient.

[0040] Alternatively, the second latch 120 can be movably mounted on the lid body 100 and linked with the first latch 110. This allows the first latch 110 to move the second latch 120 to its engaged position when flipped to its engaged position, and vice versa. The linkage between the second latch 120 and the first latch 110 facilitates one-handed operation of the first latch 110, and allows both latches 110 and 120 to simultaneously disengage from or engage with the lid body 200, making opening and closing the lid convenient.

[0041] The following describes in detail the box lid provided by several embodiments of this utility model.

[0042] Example 1: like Figures 1 to 6 As shown, the second latch 120 is fixed relative to the cover body 100, and the second latch 120 can release the latching relationship with the box body 200 as the cover body 100 moves.

[0043] Here, the second latch 120 is fixed relative to the lid body 100. During the opening process, the second latch 120 moves with the lid body 100, thereby releasing its engagement with the box body 200 without the need for separate folding of the second latch 120 for unlocking, making operation convenient. Similarly, during the closing process, the second latch 120 can also be engaged with the box body 200 as the lid body 100 moves, again without the need for separate folding of the second latch 120 for engagement, making operation convenient as well.

[0044] The specific process for opening the box lid can be as follows: Figure 2 As shown, first, flip and open the first latch 110 with one hand. Rotate the first latch 110 to a certain angle, and the vent 102 opens, allowing air pressure to flow between the inside and outside of the food storage container; then... Figure 3 As shown, continue pulling up the first latch 110 with one hand, while simultaneously pulling the lid body 100 to flip and lift it up. When the lid body 100 is flipped to a certain angle, the second latch 120 can be pushed diagonally to disengage from the flange structure 201 of the box body 200. At this point, the lid can be completely detached from the box body 200, and the lid can be easily opened.

[0045] The specific process of closing the lid is as follows: With the vent 102 open, use one hand to align the second latch 120 of the lid with the flange structure 201 on one side of the box body 200 and fasten it; then, using that side as a reference point, rotate the lid to press it onto the lid body, allowing the air pressure inside the box body 200 to escape through the vent 102; finally, flip the first latch 110 to fasten the other side of the box body 200, simultaneously covering the vent 102. At this point, as... Figure 1 As shown, both the first buckle 110 and the second buckle 120 fasten the box body 200. Even if there is heat inside the box body 200, the lid cannot be opened, resulting in a good sealing effect.

[0046] Furthermore, such as Figure 1 As shown, the latch of the second buckle 120 can extend towards the middle of the cover body 100, so that when the first buckle 110 is in the latched state, its latch also extends towards the middle of the cover body 100, making it convenient for the first buckle 110 and the second buckle 120 to firmly lock the box body 200.

[0047] In addition, such as Figure 2 and Figure 3 As shown, the flip opening of the first buckle 110 is away from the second end of the cover body 100. In other words, when the first buckle 110 is flipped open, the end of the first buckle 110 away from the second end of the cover body 100 is tilted upwards, so that the first buckle 110 can be released from the fastening relationship with the box body 200.

[0048] Furthermore, such as Figure 1 As shown, the second buckle 120 and the cover body 100 can be integrally formed, and the two are firmly connected and easy to process.

[0049] Furthermore, such as Figure 6 As shown, the lid body 100 can also be provided with a recessed groove 101 and a first notch 103 that are interconnected, with the first notch 103 extending from the recessed groove 101 to the first end of the lid body 100. A portion of the first latch 110 is embedded in the recessed groove 101 and rotatably connected to the lid body 100, while the other portion of the first latch 110 extends into the notch and engages with the box body 200 at the first notch 103. In this way, when the first latch 110 is engaged, its upper surface is flush with the upper surface of the lid body 100, resulting in a better appearance. Furthermore, the first latch 110 extending into the first notch 103 facilitates engagement with the box body 200 below. Additionally, the edge of the first latch 110 away from the second latch 120 can be flush with the edge of the first end of the lid body 100, preventing the first latch 110 from protruding laterally outward from the first notch 103, further enhancing its aesthetic appeal.

[0050] Specifically, such as Figures 1 to 4 , Figure 6 As shown, a rotating shaft 108 can be provided on the side wall of the settling tank 101, so that the first buckle 110 has shaft holes on both sides in the width direction for the rotating shaft 108 to extend into, which is beneficial for the first buckle 110 to rotate around the rotating shaft 108. In addition, the vent hole 102 can be provided on the bottom wall of the settling tank 101 and located below the first buckle 110, so that the first buckle 110 can cover the vent hole 102.

[0051] Of course, in other embodiments, the recessed groove 101 may not be provided on the cover body 100. Instead, the first buckle 110 may be directly provided on the upper surface of the cover body 100 and protrude relatively, so that the user can see the position of the first buckle 110 intuitively.

[0052] Furthermore, such as Figures 1 to 3 As shown, a sealing plug 112 can be provided on the lower surface of the first buckle 110 at a position corresponding to the vent 102. The sealing plug 112 is used to block the vent 102. By sealing the vent 102 with the sealing plug 112, heat leakage from the container 200 can be prevented, and the misflow of air inside and outside the container 200 can be prevented, thereby improving the sealing effect of the food storage container.

[0053] In practical applications, the sealing plug 112 can be a silicone plug. The top of the sealing plug 112 is fixed to the first snap fastener 110, and the bottom extends into the vent hole 102 and presses against the walls around the vent hole 102, resulting in a good sealing effect. In addition, the sealing plug 112 can be roughly inverted conical in shape to ensure a tight fit with the walls around the vent hole 102.

[0054] Furthermore, such as Figures 1 to 5As shown, a downwardly extending connecting rib 106 can also be provided on the lower surface of the lid body 100. A sealing ring 130 is fitted around the outer periphery of the connecting rib 106. The sealing ring 130 is used to extend into the box body 200 and abut against the inner wall of the box body 200. With this design, when the lid is placed on the box body 200, the sealing ring 130 can be pressed into the box body 200 and abut against the inner wall of the box body 200. This facilitates the discharge of some gas inside the box body 200 through the vent hole 102 during the lid-closing process, thereby creating a certain negative pressure inside the box body 200 to hold the lid in place, which can improve the sealing performance of the food storage box.

[0055] In practical applications, the outer wall of the connecting rib 106 can be provided with a groove 107. A portion of the sealing ring 130 is embedded in the groove 107, while the other portion extends out of the groove 107. The cross-section of the portion of the sealing ring 130 extending out of the groove 107 has an upwardly curved arc structure. Embedding a portion of the sealing ring 130 in the groove 107 of the connecting rib 106 improves the installation stability of the sealing ring 130 compared to directly fitting the sealing ring 130 onto the smooth outer wall of the connecting rib 106, preventing it from falling off during repeated opening and closing of the lid. Furthermore, the upwardly curved arc structure of the portion of the sealing ring 130 extending out of the groove 107 prevents interference between the sealing ring 130 and the box body 200 during insertion, ensuring the lid can be smoothly placed on the box body 200. Additionally, the curved portion of the sealing ring 130 better fits against the inner wall of the box body 200, resulting in a better seal.

[0056] Of course, the structure of the sealing ring 130 is not limited to this. The part of the sealing ring 130 extending out of the groove 111 can also be inclined upward, or the cross-section of the part of the sealing ring 130 extending out of the groove 111 can be triangular, etc., which will not be listed in detail here.

[0057] Example 2: like Figures 7 to 11 As shown, unlike the first embodiment described above, the second latch 120 is able to move laterally on the cover body 100 in a direction closer to or farther from the first end when the first latch 110 is flipped. Specifically, when the first latch 110 is flipped to its engaged position, it causes the second latch 120 to move towards the first end of the cover body 100 to the engaged position. Furthermore, when the first latch 110 is flipped to its unlocked position, it causes the second latch 120 to move away from the first end of the cover body 100 to the unlocked position.

[0058] Here, the second latch 120 is moved laterally on the lid body 100, and the second latch 120 occupies little space. Moreover, moving the second latch 120 away from the first end ensures that the second latch 120 is away from the box body 200, thereby ensuring that it is released from the fastening relationship with the box body 200. Moving the second latch 120 closer to the first end makes it easier for the second latch 120 to fasten onto the box body 200.

[0059] Furthermore, the linkage structure of the first latch 110 and the second latch 120 can be as follows: Figures 7 to 9 As shown, the second latch 120 has a downwardly extending hook 121 at one end near the first latch 110, and the first latch 110 has a slot 111 at one end near the second latch 120. The first latch 110 is rotatably connected to the cover body 100 via a pivot 108, which is closer to the first end than the slot 111. When the first latch 110 is flipped to its unlocked position, the slot 111 moves downward and disengages from the hook 121. At the same time, the sidewall of the slot 111 near the first end presses against the upper surface of the hook 121 and pushes the first latch 110 away from the first end. When the first latch 110 is flipped to its engaged position, the sidewall of the slot 111 near the second end presses against the lower surface of the hook 121 and pushes the first latch 110 closer to the first end.

[0060] During the flipping process of the first buckle 110, the movement of the second buckle 120 is achieved through the linkage of the buckle groove 111 and the buckle hook 121. The structure is simple, easy to process, and the transmission is stable and reliable.

[0061] The specific process of opening the box lid is as follows: With one hand, flip the first latch 110 open. When the first latch 110 is rotated to a certain angle, the vent 102 opens, allowing air pressure to flow between the inside and outside of the box 200. Simultaneously, flipping the first latch 110 causes the slot 111 at the tail end of the first latch 110 to push the second latch 120 outwards, disengaging the latch tongue at the front end of the second latch 120 from the flange structure 201 of the box 200. At this point, as... Figure 8 As shown, the first latch 110 and the second latch 120 are both disengaged from the box body 200, and the box lid can be opened easily.

[0062] The specific process of closing the lid is as follows: With the vent 102 open, pull the first latch 110 with one hand to place the lid on the box body 200; flip the first latch 110 until it engages with the flange structure 201 of the box body 200, while simultaneously closing the vent 102 to completely seal the inside of the box body 200. As the first latch 110 flips, its tail end slot 111 pulls the second latch 120 inward, until the tongue of the second latch 120 engages with the flange structure 201 of the box body 200. At this point, as... Figure 7As shown, both the first buckle 110 and the second buckle 120 fasten the box body 200. Even if there is heat inside the box body 200, the lid cannot be opened, resulting in a good sealing effect.

[0063] Of course, in other embodiments, a hook 121 can be provided on the first buckle 110 and a slot 111 can be provided on the second buckle 120 to achieve linkage between the two.

[0064] Furthermore, such as Figure 7 and Figure 9 As shown, the lid body 100 can be provided with an interconnected recess 101, a first notch 103, and a second notch 104. The first notch 103 extends from the recess 101 to a first end of the lid body 100, and the second notch 104 extends from the recess 101 to a second end of the lid body 100. A portion of the first latch 110 extends into the recess 101 and is rotatably connected to the lid body 100. At this time, the rotating shaft 108 can be provided on the side wall of the recess 101. The first latch 110 has a shaft hole for the rotating shaft 108 to be inserted, thereby realizing the flipping of the first latch 110 relative to the rotating shaft 108. The other portion of the first latch 110 extends into the first notch 103 and is fastened to one side of the box body 200 at the first notch 103. A portion of the second latch 120 extends into the recess 101, and the other portion extends into the second notch 104 and is fastened to the other side of the box body 200 at the second notch 104. When the first latch 110 is engaged, the upper surface of the lid body 100, the upper surface of the first latch 110, and the upper surface of the second latch 120 are flush, which improves the appearance of the lid.

[0065] Furthermore, when the first latch 110 and the second latch 120 are engaged, the outer peripheral edge of the first latch 110 is flush with the first end edge of the cover body 100, and the outer peripheral edge of the second latch 120 is flush with the second end edge of the cover body 100. The first latch 110 does not protrude laterally outward from the first notch 103, and the second latch 120 does not protrude laterally outward from the second notch 104, resulting in a good aesthetic appearance.

[0066] Of course, in other embodiments, the recessed groove 101 may not be provided on the cover body 100. Instead, the first buckle 110 and the second buckle 120 may be directly provided on the upper surface of the cover body 100, protruding relatively, so that the user can easily see the position of the two buckles. Alternatively, only the second buckle 120 may be provided in the recessed groove 101, while the first buckle groove 111 protrudes relatively, so that the user can quickly find the position of the first buckle 110 and flip the first buckle 110.

[0067] Furthermore, such as Figure 9As shown, a guide structure 105 can also be provided on the inner wall of the sink 101 to guide the second latch 120 to move along the guide structure 105 to move closer to or away from the second end. This design facilitates the movement of the second latch 120 along a set path, thereby ensuring that the second latch 120 is accurately engaged with the box 200, or accurately moved to the unlocking position to release the engagement with the box 200.

[0068] In specific applications, such as Figure 9 As shown, the guide structure 105 can be a guide rib provided on the side wall of the settling tank 101, and the second buckle 120 has a guide groove on its side. The guide rib is inserted into the guide groove so that the second buckle 120 moves along the guide rib during movement. Of course, the guide structure 105 can also be a guide rib provided on the bottom wall of the settling tank 101, or a guide groove provided on the side wall of the settling tank 101, etc., which will not be listed in detail here.

[0069] In addition, such as Figure 7 , Figure 10 and Figure 11 As shown, the lid of this embodiment may also have the above-mentioned sealing plug 112, sealing ring 130 and other structures, which will not be described in detail here.

[0070] Furthermore, the second latch 120 may not necessarily move laterally. For example, the second latch 120 may be able to flip relative to the cover body 100. Specifically, the first latch 110 may be able to flip the second latch 120 to its latched position when flipped to its engaged position, and the first latch 110 may also be able to flip the second latch 120 to its unlocked position when flipped to its unlocked position.

[0071] At this time, the linkage structure of the first buckle 110 and the second buckle 120 may also include a hook 121 and a groove 111, so that the hook 121 extends into the groove 111, one side wall of the groove 111 is above the hook 121, and the other side wall of the groove 111 is below the hook 121, so as to realize the linkage between the two.

[0072] Specifically, when the hook 121 is located on the second buckle 120 and the slot 111 is located on the first buckle 110, when the first buckle 110 is flipped up, the side wall of the slot 111 above the hook 121 can press down on the second buckle 120, thereby causing the end of the second buckle 120 near the second end of the cover body 100 to flip up and release the fastening relationship with the box body 200. When the first buckle 110 is flipped and fastened, the side wall of the slot 111 below the hook 121 can lift one end of the second buckle 120, thereby causing the end of the second buckle 120 near the second end of the cover body 100 to descend and fasten onto the box body 200.

[0073] Of course, in other embodiments, the hook 121 can be disposed on the first buckle 110 and the slot 111 can be disposed on the second buckle 120.

[0074] The movement of the second latch 120 can be varied and is not limited to the above embodiments. The linkage structure between the first latch 110 and the second latch 120 can also be varied and is not limited to the above embodiments.

[0075] like Figure 1 and Figure 7 As shown, a second aspect of the present invention provides a food storage box, which includes: a box body 200; a lid as described in any of the above embodiments, with a first buckle 110 and a second buckle 120 fastened to opposite sides of the box body 200.

[0076] The food storage container provided in this embodiment has the lid of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be repeated here.

[0077] Furthermore, such as Figure 1 and Figure 7 As shown, the top of the side wall of the box 200 has an outwardly extending flange structure 201, and the first buckle 110 and the second buckle 120 can be fastened to the lower surface of the flange structure 201. There is no need to make additional holes or slots in the box 200 for the two buckles to extend into, the box 200 has a simple structure and is easy to process.

[0078] Furthermore, the lid can be a plastic lid, and the box body 200 can be a plastic box body or a glass box body.

[0079] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. It should be understood that, to those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
