[0001] The utility model relates to the technical field of heat preservation appliances, in particular to a heat preservation container. Background Art

[0002] Due to its good heat preservation performance, the heat preservation container has become an essential item in people's daily life. When outdoors, users usually put high-temperature food or soup into the heat preservation container for carrying, so that warm food can be eaten outdoors. The heat preservation container generally includes a container body, an inner cover assembly that can be covered on the container body, and an outer cover. The outer cover is detachably connected to the container body, and the inner cover assembly is used to keep the food in the container body warm and sealed. However, the inner cover assembly and the outer cover are generally of an integral structure or a fixed connection structure, which makes it easy for dirt and grime to accumulate between the inner cover assembly and the outer cover, affecting the use safety. Summary of the Utility Model

[0003] This application provides a heat preservation container, which is used to solve the problem that dirt and grime easily accumulate between the inner cover and the outer cover of the heat preservation container, affecting the use safety.

[0004] This application provides a heat preservation container, which includes a container body and a container cover, and the container body includes a first opening.

[0005] The container cover can be covered on the first opening, and the container cover includes an inner cover and an outer cover sleeved on the outside of the inner cover.

[0006] Wherein, the container cover further includes a locking member, and the locking member can move relative to the inner cover and the outer cover to make the container cover in a locked state or an unlocked state.

[0007] In the locked state, the locking member is connected to the inner cover and the outer cover to limit the relative movement between the inner cover and the outer cover. In the unlocked state, the locking member is separated from at least one of the inner cover and the outer cover to release the locked state between the inner cover and the outer cover.

[0008] In this solution, when the container cover is used to cover the container body, the outer cover of the container cover is used to be detachably connected to the container body. At this time, the inner cover and the outer cover of the container cover are connected by the locking member, and the user can pick up the heat preservation container through the outer cover, so as to facilitate the carrying of the heat preservation container. When it is necessary to clean the container cover (the container cover is in the unlocked state), drive the locking member to move relative to the container cover, so that the locking member can be disconnected from at least one of the inner cover and the outer cover, and then the inner cover and the outer cover can be disconnected, and the two can move relative to each other, so that the inner cover and the outer cover are detachable, which is convenient for the user to clean the container cover, reduces the risk of dirt and grime accumulation on the container cover, is beneficial to improving the cleanliness of the container cover, and further is beneficial to improving the cleanliness and use safety of the heat preservation container.

[0009] When the container lid needs to be in the locked state, drive the locking member to move relative to the container lid so that the locking member can be connected to the inner lid and the outer lid, so that the inner lid can be connected to the outer lid, and the inner lid and the outer lid cannot be separated from each other, facilitating the user to pick up the thermal insulation container through the outer lid.

[0010] Therefore, the container lid can detachably connect the inner lid and the outer lid through the locking member, so that the user can clean the container lid, which is beneficial to improving the cleanliness of the container lid.

[0011] In this solution, the locking member includes a limiting portion and a sliding portion fixed to the limiting portion. The sliding portion can slide relative to the inner lid to make the container lid in the locked state or the unlocked state. The outer lid includes a limiting and mating portion.

[0012] In the locked state, the limiting portion is in limiting cooperation with the limiting and mating portion. In the unlocked state, the limiting portion is separated from the limiting and mating portion.

[0013] In this solution, the locking member provided on the inner lid can cooperate with or disengage from the limiting and mating portion of the outer lid through the limiting portion, enabling the inner lid and the outer lid to be connected or disconnected, facilitating the user to switch the state of the container lid according to actual needs.

[0014] In this solution, the limiting portion is a flanging structure extending radially outward along the container lid, and the limiting and mating portion is a groove provided on the outer lid.

[0015] The sliding portion can slide relative to the inner lid along the radial direction of the container lid to make the limiting portion overlap or disengage from the limiting and mating portion.

[0016] In this solution, the limiting portion and the limiting and mating portion are connected by overlapping to limit the relative movement of the inner lid and the outer lid along the height direction of the container lid. When removing the container lid from the container body, the risk of the inner lid and the outer lid being separated from each other along the height direction of the container lid is reduced, and the reliability and stability of the connection between the inner lid and the outer lid are improved.

[0017] In this solution, the container lid further includes a first elastic member. Along the radial direction of the container lid, one end of the first elastic member is connected to the sliding portion, and the other end is connected to the inner lid.

[0018] In this solution, during the process of switching from the locked state to the unlocked state, along the radial direction of the container lid, the locking member is driven to move towards the center of the container lid, the first elastic member is compressed, and the limiting portion is disengaged from the limiting and cooperating portion, so that the container lid is switched to the unlocked state. Subsequently, the driving force applied to the locking member is cancelled, and the locking member can automatically reset to the position where the limiting portion and the limiting and cooperating portion are engaged under the action of the resilience of the first elastic member, which is convenient for the assembly of the container lid. At the same time, in the locked state, the first elastic member has a resilience force along the radial direction of the container lid, and this resilience force can push the locking member to move radially outwards to improve the reliability and stability of the cooperation between the limiting portion and the limiting and cooperating portion.

[0019] In this solution, the locking member further includes a driving portion connected to the sliding portion and the limiting portion, the inner lid is provided with a slide rail, and the sliding portion can slide along the slide rail.

[0020] The top of the slide rail is covered with a blocking portion. The blocking portion has a second opening, and the driving portion extends out through the second opening. In the unlocked state, the locking member can abut against the blocking portion.

[0021] In this solution, during the process of the locking member sliding relative to the container lid, the second opening a of the blocking portion can limit the stroke of the user driving the driving portion, thereby limiting the stroke of the locking member, reducing the risk of the locking member disengaging from the slide rail, and further improving the reliability and stability of the state switching of the container lid.

[0022] In this solution, a fixing groove is provided inside the slide rail, a protruding column is provided on the sliding portion, one end of the first elastic member is sleeved on the protruding column, the other end is fixed in the fixing groove, and one end of the protruding column extends into the fixing groove.

[0023] In this solution, the fixing groove is used to fix the first elastic member. One end of the first elastic member is sleeved on the protruding column, and the other end is located in the fixing groove to reduce the risk of the first elastic member shaking relative to the locking member and improve the reliability of the movement of the locking member. At the same time, one end of the protruding column extends into the fixing groove so that the fixing groove can guide the sliding of the sliding portion and improve the reliability of the sliding of the sliding portion.

[0024] In this solution, the limiting and cooperating portion is an annular structure so that the inner lid and the outer lid can rotate relative to each other.

[0025] In this solution, when the heat preservation container needs to be opened, since the limiting portion of the locking member located on the inner cover is connected to the limiting matching portion of the outer cover by overlapping, in the process of driving the outer cover to rotate relative to the container body, the annular limiting matching portion will not block the rotation of the outer cover relative to the inner cover, so that the inner cover does not rotate with the outer cover, that is, in the process of disconnecting the container cover from the container body, the user only needs to provide an external force to drive the outer cover to rotate, thereby facilitating the opening of the cover. Similarly, in the process of connecting the container cover to the container body, the user only needs to provide an external force to drive the outer cover to rotate, thereby facilitating the closing of the cover. When the outer cover is rotated to disconnect from the container body, since the inner cover and the outer cover are connected by the locking member (the two cannot move relative to each other in the height direction), the user only needs to lift the outer cover to remove the container cover from the container body.

[0026] In this embodiment, the inner cover is provided with an exhaust hole, and the container cover also includes an exhaust member installed on the exhaust hole. The exhaust member can move along the height direction of the container cover, or at least part of the structure of the exhaust member can be elastically deformed to block or open the exhaust hole.

[0027] In this solution, the exhaust member provided on the container cover can move along the height direction of the container cover, or can be elastically deformed, so as to open the exhaust hole, which is conducive to balancing the pressure difference between the container body and the outside, reducing the risk of difficulty for users to open the container cover, and improving the user experience. In addition, when the exhaust member blocks the exhaust hole, the container body is in a sealed state, which is conducive to improving the heat preservation effect of the food in the container body.

[0028] In this solution, the exhaust member includes a mounting portion, a sealing portion and a pressing portion. Along the height direction of the container cover, the mounting portion is located between the sealing portion and the pressing portion. The mounting portion is installed on the exhaust hole. Along the height direction of the container cover, the sealing portion is located on the side of the inner cover facing the container body, and the pressing portion is located on the side of the inner cover facing away from the container body. At least the pressing portion can be elastically deformed.

[0029] When the pressing portion is pressed to elastically deform the pressing portion, the blocking portion can be driven to move toward the container body to open the exhaust hole.

[0030] In this solution, the pressing portion of the exhaust member can be deformed, so that the exhaust member can move relative to the container cover, so that the exhaust member can open the exhaust hole and balance the pressure difference between the container body and the outside, so that the user can open the container cover more easily.

[0031] In this solution, the exhaust member further includes a handle extending along the height direction of the container cover.

[0032] In this solution, the hand-held portion facilitates pulling down the exhaust member and assembling it on the inner cover.

[0033] In this solution, the exhaust component is made of one-piece silicone material.

[0034] In this solution, the pressing part, the mounting part and the sealing part of the exhaust part are an integrally formed structure and can be elastically deformed, so that it is convenient to install the exhaust part on the exhaust hole. When the exhaust part blocks the exhaust hole, the elastically deformable sealing part can improve the reliability of blocking the exhaust hole and improve the thermal insulation effect.

[0035] In this solution, the exhaust member includes a mounting portion, a sealing portion and a pressing portion. The mounting portion is mounted on the exhaust hole and can move along the exhaust hole. Along the height direction of the container cover, the sealing portion is located on the side of the inner cover facing the container body, and the pressing portion is located on the side of the inner cover facing away from the container body.

[0036] The exhaust member further includes a second elastic member, one end of which is connected to the pressing portion, and the other end of which is connected to the inner cover.

[0037] In this solution, when the air pressure in the container is relatively high, the pressing part is pressed to drive the blocking part to move toward the container body and the second elastic member is compressed to open the exhaust hole, thereby releasing the positive pressure in the container body. At the same time, when the air pressure in the container is relatively low, the air pressure in the container body will generate suction on the exhaust member, thereby driving the blocking part to move toward the container body and the second elastic member is compressed to open the exhaust hole, thereby releasing the negative pressure in the container body, so that the user can open the container cover more easily.

[0038] In this solution, the top wall of the outer cover has a third opening, and a portion of the structure of the inner cover and a portion of the structure of the locking member are exposed through the third opening.

[0039] In this solution, the container cover is provided with a third opening so that the user can directly drive the driving part of the locking member and the pressing part of the exhaust member, which is beneficial to improving the user experience.

[0093] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of this application are described from the angles shown in the drawings and should not be construed as a limitation on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0094] The embodiments of this application provide a heat-insulating container 1, as Figures 1-4 shown, the heat-insulating container 1 includes a container body 11 and a container lid 12. The container body 11 includes a first opening 111, and the container lid 12 can be closed on the first opening 111. The container lid 12 includes an inner lid 122 and an outer lid 121 sleeved outside the inner lid 122. Among them, as Figure 1 and Figure 2 shown, the container lid 12 further includes a locking member 123. The locking member 123 can move relative to the inner lid 122 and the outer lid 121 to make the container lid 12 in a locked state or an unlocked state.

[0095] In the locked state, as Figure 1 shown, the locking member 123 is connected to the inner lid 122 and the outer lid 121 to limit the relative movement between the inner lid 122 and the outer lid 121. In the unlocked state, the locking member 123 is separated from at least one of the inner lid 122 and the outer lid 121 to release the locked state between the inner lid 122 and the outer lid 121.

[0096] Specifically, when the container lid 12 is used to cover the container body 11, the outer lid 121 of the container lid 12 is detachably connected to the container body 11. At this time, the inner lid 122 of the container lid 12 is connected to the outer lid 121 through the locking member 123. The user can pick up the heat-insulating container 1 through the outer lid 121, thus facilitating the carrying of the heat-insulating container 1. When the container lid 12 needs to be cleaned (the container lid 12 is in the unlocked state), the locking member 123 is driven to move relative to the container lid 12 so that the locking member 123 can be disconnected from at least one of the inner lid 122 and the outer lid 121, and then the inner lid 122 and the outer lid 121 can be disconnected, and the two can move relative to each other, so that the inner lid 122 and the outer lid 121 are detachable, which is convenient for the user to clean the container lid 12, reduces the risk of the container lid 12 being contaminated, is beneficial to improving the cleanliness of the container lid 12, and further is beneficial to improving the cleanliness and use safety of the heat-insulating container 1.

[0097] When the container lid 12 is in the locked state, the locking member 123 is driven to move relative to the container lid 12 so that the locking member 123 can be connected to the inner lid 122 and the outer lid 121, so that the inner lid 122 can be connected to the outer lid 121, and the inner lid 122 and the outer lid 121 cannot be separated from each other, which is convenient for the user to pick up the heat-insulating container 1 through the outer lid 121.

[0098] Therefore, the container lid 12 can detachably connect the inner lid 122 and the outer lid 121 through the locking member 123, so that the user can clean the container lid 12, which is beneficial to improving the cleanliness of the container lid 12.

[0099] Among them, the container body 11 includes a housing 112, and the outer lid 121 can be threadedly connected to the housing 112.

[0100] In addition, in a possible implementation manner, as Figure 3 shown, the container body 11 further includes a first container body 113, the first container body 113 is located inside the housing 112, and the first container body 113 is used for holding food ingredients.

[0101] In a possible implementation manner, as Figure 4 shown, the container body 11 may further include a second container body 114 located inside the first container body 113 and a third container body 115 located inside the second container body 114. The first container body 113, the second container body 114, and the third container body 115 are all used for holding food ingredients, so that the user can store different types of food ingredients in different areas, and it is beneficial to increase the space for the container body 11 to hold food ingredients, and further improve the user experience.

[0102] In a possible implementation manner, as Figures 5-8As shown in the figure, the locking member 123 includes a limiting portion 1231 and a sliding portion 1232 fixed to the limiting portion 1231. The sliding portion 1232 can slide relative to the inner cover 122 to bring the container lid 12 into a locked state or an unlocked state, that is, the locking member 123 is slidably connected to the inner cover 122. The outer cover 121 includes a limiting and mating portion 1211. In the locked state, the limiting portion 1231 is in limiting and mating with the limiting and mating portion 1211. In the unlocked state, the limiting portion 1231 is separated from the limiting and mating portion 1211.

[0103] When the container lid 12 needs to be in the unlocked state, the sliding portion 1232 of the locking member 123 is driven to slide relative to the inner cover 122 to drive the limiting portion 1231 to move relative to the inner cover 122. Further, the limiting portion 1231 can be disengaged from the limiting and mating portion 1211, and the limiting portion 1231 and the limiting and mating portion 1211 no longer restrict the relative movement of the inner cover 122 and the outer cover 121 in the height direction, so that the inner cover 122 can be disengaged from the outer cover 121, and then the inner cover 122 can be removed from the outer cover 121 for cleaning.

[0104] When the container lid 12 needs to be in the locked state, the sliding portion 1232 of the locking member 123 is driven to slide relative to the inner cover 122 to drive the limiting portion 1231 to move relative to the inner cover 122. Further, the limiting portion 1231 can be mated with the limiting and mating portion 1211. At this time, the limiting portion 1231 and the limiting and mating portion 1211 in the mated state can restrict the relative movement of the inner cover 122 and the outer cover 121 in the height direction, so that the inner cover 122 can be connected to the outer cover 121. When the outer cover 121 of the container lid 12 is connected to the container body 11, the thermal insulation container 1 can be picked up through the outer cover 121.

[0105] Therefore, the locking member 123 provided on the inner cover 122 can connect or disconnect the inner cover 122 and the outer cover 121 by mating or disengaging the limiting portion 1231 with the limiting and mating portion 1211 of the outer cover 121, which is convenient for the user to switch the state of the container lid 12 according to actual needs.

[0106] In a possible implementation manner, as Figure 7 shown, the limiting portion 1231 is a flanging structure extending radially outward along the container lid 12, and the limiting and mating portion 1211 is a groove provided on the outer cover 121. The sliding portion 1232 can slide relative to the inner cover 122 along the radial direction of the container lid 12 to lap or disengage the limiting portion 1231 and the limiting and mating portion 1211.

[0107] In this embodiment, the limiting portion 1231 and the limiting and cooperating portion 1211 are connected by lapping to limit the relative movement of the inner lid 122 and the outer lid 121 in the height direction of the container lid 12. When the container lid 12 is removed from the container body 11, the risk of the inner lid 122 and the outer lid 121 being disengaged from each other in the height direction of the container lid 12 is reduced, and the reliability and stability of the connection between the inner lid 122 and the outer lid 121 are improved.

[0108] Specifically, the inner lid 122 is provided with a first limiting portion and a second limiting portion that are opposite to each other in the radial direction of the container lid 12. The first limiting portion is provided on the locking member 123. When the container lid 12 is removed from the container body 11 and needs to be cleaned, the locking member 123 is driven to move so that the first limiting portion is disengaged from the limiting and cooperating portion 1211. Then, the inner lid 122 on one side of the first limiting portion is inclined relative to the outer lid 121, so that the second limiting portion can be disengaged from the limiting and cooperating portion 1211, and then the inner lid 122 can be removed from the outer lid 121.

[0109] In a possible implementation manner, as Figure 6 and Figure 7 shown, the container lid 12 further includes a first elastic member 124. Along the radial direction of the container lid 12, one end of the first elastic member 124 is connected to the sliding portion 1232, and the other end is connected to the inner lid 122.

[0110] In this embodiment, during the process of switching from the locked state to the unlocked state, along the radial direction of the container lid 12, the locking member 123 is driven to move towards the center of the container lid 12, the first elastic member 124 is compressed, and the limiting portion 1231 is disengaged from the limiting and cooperating portion 1211, so that the container lid 12 is switched to the unlocked state. Then, the driving force applied to the locking member 123 is cancelled, and the locking member 123 can automatically reset to the position where the limiting portion 1231 is engaged with the limiting and cooperating portion 1211 under the action of the resilience of the first elastic member 124, which is convenient for the assembly of the container lid 12. At the same time, in the locked state, the first elastic member 124 has a resilience force along the radial direction of the container lid 12, and this resilience force can push the locking member 123 to move radially outwards to improve the reliability and stability of the cooperation between the limiting portion 1231 and the limiting and cooperating portion 1211.

[0111] In addition, in a possible implementation manner, one end of the first elastic member 124 can be sleeved on the sliding portion 1232 of the locking member 123, and the other end can be clamped, adhered or welded to the inner lid 122. This application does not limit the connection manner of the first elastic member 124 with the locking member 123 and the inner lid 122.

[0112] In a possible implementation manner, as Figure 6 and Figure 7As shown, the locking member 123 further includes a driving portion 1233 connected to the sliding portion 1232 and the limiting portion 1231. The inner cover 122 is provided with a slide rail 1223. The sliding portion 1232 can slide along the slide rail 1223. The limiting portion 1231 and the driving portion 1233 are located outside the slide rail 1223. The top of the slide rail 1223 is covered with a blocking portion 1224. The blocking portion 1224 has a second opening 1224a. The driving portion 1233 extends out through the second opening 1224a. In the unlocked state, the locking member 123 can abut against the blocking portion 1224.

[0113] In this embodiment, during the process of the locking member 123 sliding relative to the container cover 12, the second opening 1224a of the blocking portion 1224 can limit the stroke of the user driving the driving portion 1233 to move, thereby limiting the stroke of the locking member 123 to move, reducing the risk of the locking member 123 disengaging from the slide rail 1223, and thus improving the reliability and stability of the container cover 12 switching states.

[0114] In addition, the blocking portion 1224 can be a cover plate covering the slide rail 1223 for facilitating the installation of the locking member 123.

[0115] Among them, as Figure 7 shown, an avoidance groove 1234 is provided between the sliding portion 1232 and the driving portion 1233. The avoidance groove 1234 is used to avoid the blocking portion 1224 so that the sliding portion 1232 can drive the limiting portion 1231 to move to the unlocked position, improving the feasibility of the container cover 12 switching to the unlocked state.

[0116] In a possible implementation manner, as Figure 6 and Figure 8 shown, a fixing groove 1223a is provided inside the slide rail 1223. The sliding portion 1232 is provided with a protruding column 1232a. One end of the first elastic member 124 is sleeved on the protruding column 1232a, and the other end is fixed in the fixing groove 1223a, and one end of the protruding column 1232a extends into the fixing groove 1223a.

[0117] In this embodiment, the fixing groove 1223a is used to fix the first elastic member 124. One end of the first elastic member 124 is sleeved on the protruding column 1232a, and the other end is located in the fixing groove 1223a to reduce the risk of the first elastic member 124 shaking relative to the locking member 123 and improve the reliability of the movement of the locking member 123. At the same time, one end of the protruding column 1232a extends into the fixing groove 1223a so that the fixing groove 1223a can guide the sliding of the sliding portion 1232 and improve the reliability of the sliding of the sliding portion 1232.

[0118] In a possible implementation manner, as Figure 1 shown, the limiting and mating portion 1211 is a ring structure so that the inner cover 122 and the outer cover 121 can rotate relative to each other.

[0119] In this embodiment, when the heat preservation container 1 needs to be opened, since the limiting portion 1231 of the locking member 123 located on the inner lid 122 is connected to the limiting mating portion 1211 of the outer lid 121 in a lapping manner, during the process of driving the outer lid 121 to rotate relative to the container body 11, the annular limiting mating portion 1211 will not block the rotation of the outer lid 121 relative to the inner lid 122, so that the inner lid 122 does not rotate together with the outer lid 121. That is, during the process of disconnecting the container lid 12 from the container body 11, the user only needs to provide an external force to drive the outer lid 121 to rotate, which is convenient for opening the lid. Similarly, during the process of connecting the container lid 12 to the container body 11, the user only needs to provide an external force to drive the outer lid 121 to rotate, which is convenient for closing the lid. When the outer lid 121 rotates to be disconnected from the container body 11, since the inner lid 122 is connected to the outer lid 121 through the locking member 123 (the two cannot move relative to each other in the height direction), the user only needs to lift the outer lid 121 to remove the container lid 12 from the container body 11.

[0120] As Figure 1 and Figure 9 shown, a first seal 127 is provided on the side of the inner lid 122 facing the container body 11. When the container lid 12 is closed on the first opening 111, the first seal 127 is used to seal the gap between the inner lid 122 and the first container body 113. During the process of opening and closing the lid, since the inner lid 122 does not rotate with the outer lid 121 when the outer lid 121 rotates, the first seal 127 connected to the inner lid 122 is stationary relative to the container body 11, and thus there is no risk of generating noise due to the friction between the rotating first seal 127 and the inner wall of the container body 11, thereby achieving the effect of quiet opening and closing and improving the user experience.

[0121] In a possible implementation manner, as Figure 7 、 Figure 9 and Figure 10 shown, the inner lid 122 is provided with an exhaust hole 1225, and the container lid 12 further includes an exhaust member 125 installed in the exhaust hole 1225. The exhaust member 125 can move along the height direction of the container lid 12, or at least part of the structure of the exhaust member 125 can elastically deform to block or open the exhaust hole 1225.

[0122] Therefore, the container lid 12 is provided with an exhaust member 125 that can move along the height direction of the container lid 12 or can elastically deform, and thus can open the exhaust hole 1225, which is beneficial to balancing the pressure difference between the container body 11 and the outside world, reducing the risk of difficulty for the user to open the container lid 12, and is beneficial to improving the user experience. In addition, when the exhaust member 125 blocks the exhaust hole 1225, the container body 11 is in a sealed state, which is beneficial to improving the heat preservation effect of the food materials in the container body 11.

[0123] In a possible implementation, as Figure 9 shown, the exhaust member 125 includes a mounting portion 1251, a blocking portion 1252, and a pressing portion 1253. Along the height direction of the container lid 12, the mounting portion 1251 is located between the blocking portion 1252 and the pressing portion 1253. The mounting portion 1251 is mounted on the exhaust hole 1225. Along the height direction of the container lid 12, the blocking portion 1252 is located on the side of the inner lid 122 facing the container body 11, and the pressing portion 1253 is located on the side of the inner lid 122 facing away from the container body 11. At least the pressing portion 1253 can elastically deform.

[0124] In this embodiment, as Figure 9 shown, the mounting portion 1251 is used to mount the exhaust member 125 on the inner lid 122. When the air pressure in the container body 11 is relatively large, when the pressing portion 1253 is pressed to elastically deform, it can drive the blocking portion 1252 to move in the direction of the container body 11 to open the exhaust hole 1225, and then the positive pressure in the container body 11 can be discharged. When the air pressure in the container body 11 is relatively small, the air pressure in the container body 11 will generate a suction force on the exhaust member 125, and then drive the blocking portion 1252 to move in the direction of the container body 11 to open the exhaust hole 1225, and then the negative pressure in the container body 11 can be discharged.

[0125] Therefore, the pressing portion 1253 of the exhaust member 125 can deform, enabling the exhaust member 125 to move relative to the container lid 12, so that the exhaust member 125 can open the exhaust hole 1225, balance the pressure difference between the container body 11 and the outside, so that the user can more easily open the container lid 12.

[0126] As Figure 7 shown in the embodiment, the blocking portion 1252 can elastically deform. When the air pressure in the container body 11 is relatively small, the air pressure in the container body 11 will generate a suction force on the exhaust member 125, and then drive the blocking portion 1252 to move in the direction of the container body 11 to open the exhaust hole 1225, and then the negative pressure in the container body 11 can be discharged.

[0127] In addition, on the basis of the embodiment shown in Figure 7 , along the height direction of the container lid 12, the size of the mounting portion 1251 can be larger than the size of the exhaust hole 1225, so that when the pressing portion 1253 is pressed, the exhaust member 125 can move downward, driving the blocking portion 1252 away from the exhaust hole 1225 to open the exhaust hole 1225, so that the positive pressure in the container body 11 can be discharged.

[0128] In some embodiments, the pressing portion 1253, the mounting portion 1251 and the sealing portion 1252 of the exhaust member 125 are an integrally formed structure and are all capable of elastic deformation, thereby facilitating the installation of the exhaust member 125 on the exhaust hole 1225, and when the exhaust member 125 blocks the exhaust hole 1225, the elastically deformable sealing portion 1252 can improve the reliability of blocking the exhaust hole 1225 and improve the thermal insulation effect.

[0129] The exhaust member 125 may be made of a deformable material such as silicone.

[0130] In a possible implementation, Figure 9 As shown, along the radial direction of the container cover 12 away from the mounting portion 1251, the cross-sectional area of ​​the pressing portion 1253 gradually increases.

[0131] In this embodiment, the cross-sectional area of ​​the pressing portion 1253 gradually increases, that is, the cross-sectional area at the center of the pressing portion 1253 is smaller than the cross-sectional areas on both sides. The user can more easily press the pressing portion 1253 to deform it, thereby driving the blocking portion 1252 to move so as to open the exhaust hole 1225.

[0132] In a possible implementation, Figure 9 As shown, the exhaust member 125 may further include a handle portion 1255 extending along the height direction of the container cover 12 , and along the height direction of the container cover 12 , the handle portion 1255 and the pressing portion 1253 are located on opposite sides of the blocking portion 1252 .

[0133] In this embodiment, the handle 1255 facilitates pulling down the exhaust member 125 and assembling it on the inner cover 122 .

[0134] Among them, the outer peripheral wall of the hand-held part 1255 can be provided with a protrusion to increase the friction force and further facilitate the installation of the exhaust component 125 on the inner cover 122.

[0135] In another possible implementation, Figure 10 As shown, the exhaust member 125 includes a mounting portion 1251, a sealing portion 1252 and a pressing portion 1253. The mounting portion 1251 is mounted on the exhaust hole 1225 and can move along the exhaust hole 1225. Along the height direction of the container cover 12, the sealing portion 1252 is located on the side of the inner cover 122 facing the container body 11, and the pressing portion 1253 is located on the side of the inner cover 122 facing away from the container body 11.

[0136] The exhaust member 125 further includes a second elastic member 1254 . One end of the second elastic member 1254 is connected to the pressing portion 1253 , and the other end of the second elastic member 1254 is connected to the inner cover 122 .

[0137] In this embodiment, when the air pressure in the container body 11 is relatively high, press the pressing portion 1253 to drive the blocking portion 1252 to move towards the container body 11 and the second elastic member 1254 is compressed to open the exhaust hole 1225, thereby being able to release the positive pressure in the container body 11. At the same time, when the air pressure in the container body 11 is relatively low, the air pressure in the container body 11 will generate a suction force on the exhaust member 125, thereby driving the blocking portion 1252 to move towards the container body 11 and the second elastic member 1254 is compressed to open the exhaust hole 1225, thereby being able to release the negative pressure in the container body 11, enabling the user to more easily open the container lid 12.

[0138] In a possible implementation manner, as Figure 3 shown, the top wall of the outer lid 121 has a third opening 1212, and a part of the structure of the inner lid 122 and a part of the structure of the locking member 123 are exposed through the third opening 1212.

[0139] In this embodiment, the container lid 12 is provided with the third opening 1212 so that the user can directly drive the driving portion 1233 of the locking member 123 and the pressing portion 1253 of the pressing exhaust member 125, which is beneficial to improving the user experience.

[0140] In a possible implementation manner, as Figure 7 and Figure 9 shown, the inner lid 122 further includes a connected first inner lid 1221 and a second inner lid 1222, and a heat insulation layer 126 is provided between the first inner lid 1221 and the second inner lid 1222.

[0141] In this embodiment, the heat insulation layer 126 can be styrofoam to improve the heat insulation performance of the heat insulation container 1 for the food materials in the container body 11. In addition, a second sealing member 128 is provided at the exhaust hole 1225 between the first lid body and the second lid body, which is beneficial to improving the sealing performance of the container lid 12.

[0142] Among them, the first inner lid 1221 and the second inner lid 1222 can be connected by welding.

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