Description

Technical Field

[0001] The present application relates to the technical field of daily necessities, and in particular to a container cover and a heat-insulating container. Background Art

[0002] The heat preservation container usually includes a container body and a container cover, and the container cover is usually connected to the opening of the cup body by a threaded manner to close the opening of the cup body. This connection method requires the user to hold the container body and the container cover with both hands respectively, and screw them together to install and remove the container cover, which is inconvenient to operate and affects the user experience. Utility Model Content

[0003] The present application provides a container cover and a thermal insulation container to simplify the opening operation of the container cover and improve the user experience of the thermal insulation container.

[0004] The first aspect of the present application provides a container cover, comprising:

[0005] A cover body having an inner cavity;

[0006] A support, disposed in the inner cavity;

[0007] A locking member, slidably connected to the support and capable of sliding along the radial direction of the cover body;

[0008] A portion of the locking member is exposed at the top of the cover body to form an operating portion, and another portion of the locking member can extend out of the periphery of the cover body to form a locking portion.

[0009] The container cover provided by the present application includes a cover body, a support and a locking member. The cover body has an inner cavity, and the support is accommodated in the inner cavity; the locking member is slidably connected to the support and can slide along the radial direction of the cover body to lock or release the container cover; a part of the locking member is exposed at the top of the cover body to form an operating part, and another part of the locking member can extend out of the outer periphery of the cover body to form a locking part, that is, the user only needs to apply external force to the operating part to make the locking member move along the radial direction of the cover body, so that the locking part can be retracted to open the container cover, and the opening operation is convenient, which improves the user experience. In addition, the embodiment of the present application installs the locking member on the support instead of directly installing it on the cover body, which can avoid the processing error of the cover body affecting the installation and movement of the locking member. The support provides stable support and precise guidance for the locking member, making the action of the locking member more flexible and efficient, which can not only make the operation of the locking member more labor-saving, but also reduce the risk of jamming during the action of the locking member, and ensure that the locking member can accurately lock and release the container cover.

[0010] Optionally, the container lid comprises two locking members, which are symmetrical to each other. The user can operate the two locking members by pinching them with two fingers. At the same time, after pinching the two locking members, the user can also lift the container lid upward to open the lid, which further simplifies the opening operation.

[0011] Optionally, a corresponding first elastic member is provided at one end of the locking member close to the axis of the cover body, and the two ends of the first elastic member elastically abut against the locking member and the support respectively. In a natural state, the locking portion can stably stay in a state of extending out of the cover body, ensuring that the container cover and the container body will not separate from each other during use. In addition, the two ends of the first elastic member are a fixed end and a movable end, respectively, so that the position of the first elastic member will not change, thereby making the action of the locking member more accurate and efficient.

[0012] Optionally, the support includes two oppositely arranged sliding grooves, and a first matching portion is protruding from the bottom of the locking member. The first matching portion is inserted into the sliding groove and forms a sliding fit with the sliding groove, thereby providing precise guiding effect on the locking member and reducing the shaking that may occur during the sliding process of the locking member.

[0013] Optionally, the support includes two oppositely arranged support columns, and a second matching portion is protruding from the side of the locking member facing the support. The second matching portion is clamped on both sides of the support column and forms a sliding fit with the support column to increase the matching area between the locking member and the support, thereby increasing the stability of the relative movement between the two and reducing the shaking of the locking member during movement.

[0014] Optionally, the cover body has a channel passing through both ends, the channel is separated from the inner cavity, and the container cover further comprises: a valve assembly slidably connected to the cover body to open or close the channel;

[0015] A water outlet control member, the water outlet control member is movably connected to the cover body, the water outlet control member drives the valve assembly to move, and a user applies an external force to the water outlet control member, so that the valve assembly can open or close the channel as needed, thereby improving the convenience of the pouring operation;

[0016] The water outlet control member is sandwiched between the two locking members, and the locking member further comprises a guide portion, and the guide portion and the water outlet control member abut against each other;

[0017] When the two locking members are close to each other, the guide part converts the radial movement of the locking members into movement of the water outlet control member, and the water outlet control member drives the valve assembly to open the channel. The user can open the channel while opening the cover, which can not only connect the internal space of the container body with the external atmosphere to prevent high-temperature gas from spraying out and scalding the user, but also discharge the residual liquid in the channel to prevent the liquid from dripping or spilling after opening the cover, affecting the user experience.

[0018] Optionally, the guide portion is arranged at the top edge of the locking member, and along the bottom-up direction, the guide portion gradually tilts toward the direction close to the water outlet control member. On the one hand, the guide portion can be arranged opposite to the operating member, and the external force applied by the user to the operating member is directly against the guide portion, so that no torque swinging up and down is formed on the locking member, thereby increasing the stability of the locking member's action; on the other hand, the height difference between the water outlet control member and the locking member can be reduced, making the overall structure more compact and improving space utilization.

[0019] Optionally, the locking member is provided with two guide portions, which are spaced apart along the extension direction of the water outlet control member and are parallel to each other, so that the force on the water outlet control member is more uniform and the water outlet control member is prevented from swinging left and right.

[0020] Optionally, the valve assembly comprises:

[0021] a valve disc, the valve disc being disposed at one end of the passage;

[0022] A valve stem is slidably connected to the cover body, and an exhaust groove is provided on the outer periphery of the valve stem, and the exhaust groove extends along the axial direction of the valve stem;

[0023] The valve stem is inserted into the valve disc, and the valve disc can slide along the valve stem to open or close the exhaust groove.

[0024] On the one hand, the valve stem can move independently of the valve disc. By providing the exhaust groove, the circumferential contact area between the valve stem and the valve disc is reduced, thereby reducing the resistance to the relative movement of the valve stem and the valve disc, making the operation of opening the channel more convenient and labor-saving. On the other hand, after the stopper and the valve disc are separated from each other, the upper and lower sides of the valve disc are connected to each other through the exhaust groove, so that the high-temperature gas in the container body can be quickly discharged, so that the air pressure in the container body is reduced, avoiding the pressure difference between the upper and lower sides of the valve disc, and ensuring that the valve disc can be opened normally.

[0025] Optionally, the height of the container cover is 45 mm to 80 mm, which can not only increase the heat insulation performance of the container cover to meet the use requirements of the heat preservation container, but also enable the heat preservation container to have a better use experience.

[0026] Optionally, the cover body is provided with a connecting protrusion, the connecting protrusion protrudes upward from the bottom of the inner cavity, and the support is buckled and connected to the connecting protrusion, so as to achieve the installation and fixation of the support and prevent the support from moving or shaking during use, causing the locking member to deviate from the predetermined position.

[0027] A second aspect of the present application provides a heat-insulating container, which includes a container body and any one of the container covers provided in the present application, wherein the container body is provided with a locking groove, and the locking piece cooperates with the locking groove.

[0028] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0065] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0066] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0067] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0068] like Figure 1-Figure 7 As shown, an embodiment of the present application provides a container cover, which can cover the opening of the container body, and the container cover includes a cover body 1, a support 2 and a locking member 3. The cover body 1 has an inner cavity 11, and the support 2 is accommodated in the inner cavity 11. The locking member 3 is slidably connected to the support 2 and can slide along the radial direction of the cover body 1 to lock or release the container cover. A part of the locking member 3 is exposed at the top of the cover body 1 to form an operating part 31, and another part of the locking member 3 can extend out of the periphery of the cover body 1 to form a locking part 32. In other words, the user only needs to apply an external force to the operating part 31 to move the locking member 3 along the radial direction of the cover body 1, so that the locking part 32 can be retracted to open the container cover, and the cover opening operation is convenient, which improves the user experience. In addition, the embodiment of the present application installs the locking member 3 on the support 2 instead of directly installing it on the cover body 1, which can prevent the processing error of the cover body 1 from affecting the installation and movement of the locking member 3. The support 2 provides stable support and guidance for the locking member 3, making the movement of the locking member 3 more flexible and efficient, which can not only make the operation of the locking member 3 more labor-saving, but also reduce the risk of jamming during the operation of the locking member 3, ensuring that the locking member 3 can accurately lock and release the container cover.

[0069] Among them, at least a part of the container cover is embedded in the opening of the container body, and the cover body 1 may include an inner plug and an upper cover, and the inner plug and the upper cover form the above-mentioned inner cavity 11, and the inner plug and the upper cover are detachably connected to facilitate the installation of various components in the inner cavity 11. The number of locking members 3 can be reasonably set as needed, for example, the number of locking members 3 is one, two or more than three. When there is one locking member 3, the locking member 3 can be a long inclined structure. When the number of locking members 3 is at least two, each locking member 3 is spaced around the axis of the cover body 1.

[0070] Specifically, when the locking member 3 slides in the axial direction away from the cover body 1, the locking portion 32 extends out of the cover body 1 and locks the container cover, ensuring that the container cover is stably installed on the container body; when the locking member 3 slides in the direction close to the axis of the cover body 1, the locking portion 32 retracts into the cover body 1 and releases the container cover, and the container cover can be opened normally.

[0071] Further, a corresponding first elastic member 33 is provided at one end of the locking member 3 close to the axis of the cover body 1, that is, the first elastic member 33 is arranged one-to-one with the locking member 3, and the two ends of the first elastic member 33 are elastically pressed against the locking member 3 and the support 2 respectively, so as to force the locking member 3 to move in the direction away from the axis of the cover body 1, that is, in the natural state, the locking portion 32 can stably stay in the state of extending out of the cover body 1, ensuring that the container cover and the container body will not separate from each other during use. In addition, one end of the first elastic member 33 elastically presses against the support 2 to form a fixed end, so that the position of the first elastic member 33 will not change. The other end of the first elastic member 33 elastically presses against the locking member 3 to form a movable end, so that the first elastic member 33 can push the locking member 3 to move in the direction away from the axis of the cover body 1, so that the action of the locking member 3 is more accurate and efficient. It can be understood that in other embodiments, the two ends of the first elastic member 33 can be pressed against two oppositely arranged locking members 3 respectively, so that both ends of the first elastic member 33 are movable ends.

[0072] Furthermore, there are two locking members 3, which are symmetrical to each other. The user can operate the two locking members 3 by pinching them with two fingers. At the same time, after pinching the two locking members 3, the user can also lift the container cover upward to open the cover, which further simplifies the cover opening operation.

[0073] Furthermore, when the number of locking members 3 is two, the support 2 includes two oppositely arranged slide grooves 21, and a first matching portion 34 is protruded below the locking member 3. The first matching portion 34 is inserted into the slide groove 21 and forms a sliding fit with the slide groove 21, thereby providing precise guiding effect on the locking member 3 and reducing the shaking that may be generated during the sliding process of the locking member 3.

[0074] Furthermore, the support 2 includes two relatively arranged support columns 22, and the locking member 3 is slidably connected to the support columns 22. That is to say, the two locking members 3 are respectively installed on different support columns 22, which can not only meet the supporting strength of the locking member 3, but also improve the local processing accuracy as needed, thereby providing further stable support and precise guidance for the locking member 3.

[0075] Furthermore, the support 2 also includes a connecting portion 23, the height of the connecting portion 23 is lower than the height of the support column 22, and the two support columns 22 are symmetrically distributed at both ends of the connecting portion 23. The two support columns 22 are interconnected into a whole through the locking member 3, which can not only improve the relative position accuracy of the two support columns 22, thereby improving the consistency of the actions of the two locking members 3, but also reduce the number of parts and simplify the assembly process of the container cover.

[0076] Furthermore, a second fitting portion 35 is protruded from one side of the locking member 3 facing the support 2. The second fitting portion 35 is clamped on both sides of the support column 22 and forms a sliding fit with the support column 22 to increase the fitting area between the locking member 3 and the support 2, thereby increasing the stability of the relative movement between the two and reducing the shaking of the locking member 3 during the movement.

[0077] Furthermore, the cover body 1 is provided with a positioning protrusion 12, which protrudes upward from the bottom of the inner cavity 11, and the support 2 is sleeved on the positioning protrusion 12 to form a radial positioning for the support 2, ensuring that the locking member 3 can achieve the expected locking and releasing effects. Specifically, the support 2 can be provided with a first through hole, and the positioning protrusion 12 forms a plug-in fit with the first through hole of the support 2, so as to form a precise positioning for the support 2, prevent the installation position of the support 2 from being offset, resulting in the locking member 3 being unable to achieve the expected locking and releasing effects.

[0078] Furthermore, along the direction from bottom to top, the radial dimension of the positioning protrusion 12 gradually decreases, that is, the positioning protrusion 12 is formed into a conical structure with a small top and a large bottom, which can make it easier for the positioning protrusion 12 to align with the first through hole of the support 2, making the installation of the support 2 easier, and can also adjust the position of the support 2 during the installation of the support 2 from top to bottom, so as to achieve the effect of automatic alignment and ensure that the support 2 can be installed in the predetermined position. In addition, the conical structure can also play a certain axial limiting role on the support 2 to prevent the support 2 from collapsing downward under the action of external force. It can be understood that the positioning protrusion 12 can also be set to a columnar structure with a constant radial dimension. The cross section of the positioning protrusion 12 can be set to any appropriate shape such as circular, square or polygonal as needed.

[0079] Furthermore, the cover body 1 is provided with a connecting protrusion 13, which protrudes upward from the bottom of the inner cavity 11, and the support 2 is snap-connected to the connecting protrusion 13. Specifically, one of the connecting protrusion 13 and the support 2 is provided with a snap-on protrusion 131, and the other is provided with a snap-on groove 24. When the support 2 is installed in place, the snap-on protrusion 131 is snapped into the snap-on groove 24, thereby achieving the installation and fixation of the support 2, preventing the support 2 from moving or shaking during use, causing the locking member 3 to deviate from the predetermined position. In addition, the snap-on connection method only requires pressing the support 2 from top to bottom to achieve the installation and fixation of the support 2, which is easy to operate, and can form stable and reliable axial and circumferential positioning, preventing the support 2 from offsetting in height position, and also preventing the support 2 from rotating circumferentially relative to the cover body 1, thereby stabilizing the installation of the support 2.

[0080] Furthermore, the cover body 1 has a channel 14 running through both ends, which is used to discharge the liquid in the container body, so that the pouring function can be achieved without opening the cover. Specifically, one end of the channel 14 is located at the bottom of the cover body 1, forming a water inlet connected to the container body, so that the liquid in the container body can flow into the channel 14; the other end of the channel 14 is located on the side wall of the cover body 1, forming a water outlet connected to the outside, so that the liquid in the channel 14 can flow out to the outside. The channel 14 is separated from the inner cavity 11 to prevent the parts installed in the inner cavity 11 from contacting with the liquid, resulting in contamination of the liquid or damage to the parts.

[0081] Furthermore, the container cover also includes a valve assembly 4 and a water outlet control member 5. The valve assembly 4 is slidably connected to the cover body 1 to open or close the channel 14; the water outlet control member 5 is movably connected to the cover body 1, for example, the water outlet control member 5 can be slidably connected to the cover body 1 or pivotally connected to the cover body 1, and the water outlet control member 5 drives the valve assembly 4 to move. When the user applies an external force to the water outlet control member 5, the valve assembly 4 can open or close the channel 14 as needed, thereby improving the convenience of the pouring operation.

[0082] Furthermore, the water outlet control member 5 is sandwiched between the two locking members 3, and the locking members 3 further include a guide portion 36, and the guide portion 36 and the water outlet control member 5 abut against each other. When the two locking members 3 are close to each other, the guide portion 36 converts the radial movement of the locking member 3 into the movement of the water outlet control member 5 (for example, axial movement or pivotal movement, etc.), and the water outlet control member 5 drives the valve assembly 4 to open the channel 14. When the user is opening the cover, the channel 14 can be opened, which can not only make the internal space of the container body communicate with the external atmosphere to prevent the high-temperature gas from spraying out and scalding the user, but also discharge the residual liquid in the channel 14 to prevent the liquid from dripping or spilling after opening the cover, affecting the user experience.

[0083] Specifically, along the bottom-up direction, the guide portion 36 gradually tilts toward the direction close to the water outlet control member 5. For example, the side of the guide portion 36 facing the water outlet control member 5 may be an inclined surface or an arc surface. When the two locking members 3 approach each other, the guide portion 36 pushes the water outlet control member 5 downward, thereby opening the channel 14.

[0084] Furthermore, the container cover is a poor conductor of heat, so as to reduce the heat conduction of the liquid in the container body along the container cover, and improve the thermal insulation performance of the thermal insulation container. The height of the container cover (i.e., the axial dimension of the container cover) is 45mm to 80mm. For example, the height of the container cover can be 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm or 80mm, etc., which can not only increase the thermal insulation performance of the container cover, thereby meeting the use requirements of the thermal insulation container, but also enable the thermal insulation container to have a better user experience. When the height of the container cover is less than 45mm, the matching depth between the container cover and the container body (for example, the depth of the container cover embedded in the mouth of the container body, etc.) is small, and the thermal insulation performance of the container cover is difficult to meet the requirements; when the height of the container cover is greater than 80mm, the improvement of the thermal insulation effect is not obvious, and it will also lead to an increase in the overall material cost of the thermal insulation container, and the external volume of the thermal insulation container is too large, and the actual effective volume is too small, which affects the user experience of the thermal insulation container.

[0085] It can be understood that in other embodiments, the height of the container cover can be set accordingly according to the actual application requirements of the thermal insulation container, and can be lower than 45 mm or higher than 80 mm.

[0086] Furthermore, the guide portion 36 is arranged at the top edge of the locking member 3. On the one hand, the guide portion 36 can be arranged opposite to the operating portion 31, and the external force applied by the user to the operating portion 31 is directly directed to the guide portion 36, so that no torque of up and down swinging is formed on the locking member 3, thereby increasing the stability of the action of the locking member 3; on the other hand, the height difference between the water outlet control member 5 and the locking member 3 can be reduced, making the overall structure more compact and improving the space utilization.

[0087] It can be understood that, without considering the convenience of installation, the guide portion 36 can also be set at other positions of the locking member 3. For example, the guide portion 36 is set at the bottom or middle position on the opposite side of the operating portion 31 of the locking member 3, as long as it can achieve the purpose of abutting against the water outlet control member 5.

[0088] Furthermore, the locking member 3 is provided with two guide portions 36, which are arranged at intervals along the extension direction of the water outlet control member 5, and the two guide portions 36 are parallel to each other, so that the force on the water outlet control member 5 is more uniform, and the water outlet control member 5 is prevented from swinging left and right. It can be understood that the locking member 3 can also be provided with only one guide portion 36, or more than three guide portions 36.

[0089] Further, the valve assembly 4 includes a valve stem 41 and a valve disc 42 connected to each other. The valve stem 41 is slidably connected to the cover body 1, and the valve disc 42 is disposed at one end of the channel 14 to open or close the channel 14. Specifically, the valve disc 42 can move with the valve stem 41 in a direction close to the channel 14 to close the channel 14, or the valve disc 42 can move with the valve stem 41 in a direction away from the channel 14 to open the channel 14.

[0090] The valve stem 41 and the valve disc 42 may be connected to each other in a fixed manner or in a movable manner, as long as the valve disc 42 can move with the valve stem 41. When the valve stem 41 and the valve disc 42 are connected to each other in a fixed manner, the valve stem 41 and the valve disc 42 may be connected to each other as a whole by a non-detachable manner such as injection molding, or may be connected to each other by a detachable manner such as threaded fitting or snap fitting.

[0091] Furthermore, the valve stem 41 is inserted into the valve disc 42. A stop portion 411 is provided at one end of the valve stem 41. The stop portion 411 is an annular structure protruding radially from the valve stem 41. The stop portion 411 is located on the side of the valve disc 42 away from the channel 14, so that the valve disc 42 can move toward the channel 14 together with the valve stem 41 to close the channel 14. The stop portion 411 provides an axial supporting force to the valve disc 42, thereby improving the reliability of the cooperation between the valve disc 42 and the channel 14.

[0092] Furthermore, the valve assembly 4 also includes a second elastic member 43, the upper end of the second elastic member 43 elastically presses against the valve stem 41 to force the valve stem 41 to drive the valve disc 42 to move upward, so that the valve disc 42 can stably stay in the position of closing the channel 14, ensuring that the liquid in the container body will not leak in the natural state.

[0093] Furthermore, the valve disc 42 is slidably connected to the valve stem 41, that is, the valve stem 41 and the valve disc 42 are connected to each other in a movable manner, and the valve stem 41 can move independently of the valve disc 42, which can not only achieve the effect of pre-exhaust to prevent high-temperature gas from spraying out and scalding the user, but also make the operation of opening the channel 14 more convenient and labor-saving. Specifically, the stopper 411 can elastically press against the side of the valve disc 42 away from the channel 14, thereby forming a sealing state between the stopper 411 and the valve disc 42 to prevent liquid leakage in the container body; when the channel 14 needs to be opened, the user applies an external force to the valve stem 41 to make the stopper 411 move in a direction away from the valve disc 42, and the stopper 411 and the valve disc 42 are separated from each other, thereby destroying the sealing state between the valve stem 41 and the valve disc 42, so that the high-temperature gas inside the container body can be discharged, avoiding the high-temperature gas in the container body from spraying out and scalding the user during the cover opening operation, and because the cross-section of the stopper 411 is much smaller than the cross-section of the valve disc 42, the gas pressure on the valve stem 41 is much smaller than that on the valve disc 42, making the operation of opening the channel 14 more convenient and labor-saving.

[0094] Furthermore, the stopper 411 is sleeved with a sealing member 412, which elastically presses against the side of the valve disc 42 away from the channel 14 as the stopper 411 moves, thereby ensuring that a reliable end face sealing fit can be formed between the valve stem 41 and the valve disc 42, thereby preventing the liquid in the container body from leaking along the valve stem 41 and the valve disc 42.

[0095] Furthermore, the outer circumference of the valve stem 41 is provided with an exhaust groove 413, which is recessed in the surface of the valve stem 41 and extends along the axial direction of the valve stem 41. On the one hand, by providing the exhaust groove 413, the circumferential contact area between the valve stem 41 and the valve disc 42 is reduced, thereby reducing the resistance to the relative movement of the valve stem 41 and the valve disc 42, making the operation of opening the channel 14 more convenient and labor-saving; on the other hand, after the stopper 411 and the valve disc 42 are separated from each other, the upper and lower sides of the valve disc 42 are connected to each other through the exhaust groove 413, so that the high-temperature gas in the container body can be quickly discharged, so that the air pressure in the container body is reduced, and the pressure difference between the upper and lower sides of the valve disc 42 is avoided, ensuring that the valve disc 42 can be opened normally. It can be understood that other exhaust structures can also be provided between the valve stem 41 and the valve disc 42, for example, an exhaust through hole can be provided at the position of the valve disc 42 facing the stopper 411, as long as the upper and lower sides of the valve disc 42 can be connected to each other.

[0096] The outer circumference of the valve stem 41 may be provided with only one exhaust groove 413 or at least two exhaust grooves 413. When at least two exhaust grooves 413 are provided on the outer circumference of the valve stem 41, the exhaust grooves 413 are spaced apart around the axis of the valve stem 41.

[0097] Furthermore, the valve assembly 4 further includes a third elastic member 44, the lower end of which elastically presses against the valve disc 42 to force the valve disc 42 to move downward to open the channel 14, thereby realizing the pouring function. It can be understood that the valve disc 42 can move downward to open the channel 14 by its own gravity or other forces.

[0098] In addition, an embodiment of the present application also provides an insulation container, which includes a container body and any one of the container lids provided in the embodiment of the present application, the container body is provided with a locking groove, and the locking piece 3 cooperates with the locking groove to lock the container lid and the container body to each other.

[0099] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
