[0007] In some embodiments, the snap fastener assembly includes an unlocking member, and the operating member is provided with a linkage part. The linkage part is movably connected to the unlocking member in a first direction. When the snap fastener mechanism is in the locked position, the linkage part restricts the movement of the unlocking member in a second direction. The operating member is adapted to drive the snap fastener assembly to move in the second direction through the linkage part, so as to drive the locking part to unlock the cover body.

[0008] In some embodiments, the cover body is provided with a limiting part, which is located on the movement path of the operating member along the second direction. When the snap-lock mechanism is in the locked position, the limiting part restricts the movement of the operating member along the second direction, and the linkage part restricts the movement of the unlocking member along the second direction.

[0009] In some embodiments, the spring-loaded mounting member has a blocking part located along the movement path of the unlocking member in the second direction, and the unlocking member has a blocking engagement part located between the blocking part and the inner wall of the spring-loaded mounting member.

[0011] In some embodiments, the spring-loaded assembly further includes an elastic element, one end of which is connected to the inner wall of the spring-loaded mounting member, and the other end of which is connected to the unlocking member. The elastic force of the elastic element is adapted to drive the unlocking member to move in a second direction.

[0012] In some embodiments, the cover body has a guide opening, the locking part passes through the guide opening and is confined in the cover body, the guide opening has a guide wall surface, the guide wall surface is inclined in a direction away from the guide opening along a first direction, when the spring buckle mechanism drives the locking part to unlock in the cover body, the locking part is unlocked in the cover body and slides in the guide opening through the guide wall surface.

[0013] In some embodiments, the snap fastener assembly includes an unlocking member, which has an unlocking portion on the side facing the locking portion. The unlocking portion is inclined toward the locking portion along the direction from the cover body toward the snap cover, and the locking portion is inclined toward the unlocking portion along the direction from the cover body toward the snap cover. The unlocking portion is adapted to drive the locking portion to move in a second direction so that the locking portion is unlocked from the cover body.

The spring-loaded latch mechanism is adapted to move along a first direction and then along a second direction to drive the locking part to unlock from the lid body. The first direction and the second direction are distinct. Thus, by moving the spring-loaded latch mechanism to the locked position, the spring-loaded lid can be locked onto the lid body; alternatively, by moving the spring-loaded latch mechanism, the spring-loaded lid can be unlocked from the lid body. The method of moving the spring-loaded latch mechanism to unlock the spring-loaded lid is simple, convenient for opening the spring-loaded lid, and also convenient for user operation.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the embodiments of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] This invention provides a container, which can be a water cup for convenient storage and retrieval of water; the container can also be a storage container for convenient storage and retrieval of food, water, or other items. In other embodiments, the container can be other devices, and the specific design can be tailored to the specific circumstances.

[0033] See Figure 1 In some embodiments, the container includes a container body and a container lid opening and closing device 100. The container body has a receiving cavity, which can be used to hold substances such as food, water, articles, etc. The container lid opening and closing device 100 is connected to the container body and covers the receiving cavity.

[0034] This helps reduce the amount of material in the containment cavity exposed to the air, and helps reduce the amount of dust, particles and other debris entering the containment cavity.

[0035] See Figures 1 to 4In some embodiments, the container lid opening and closing device 100 includes a lid body 11, a spring-loaded lid 12, and a spring-loaded latch mechanism 13. The spring-loaded lid 12 is rotatably connected to the lid body 11. For example, the spring-loaded lid 12 can be rotatably connected to the lid body 11 via a pivot, so that the spring-loaded lid 12 can be rotated to open relative to the lid body 11. The spring-loaded lid 12 is provided with a locking part 121, which is spaced apart from the side wall of the spring-loaded lid 12.

[0036] This helps reduce stress concentration on the side wall of the spring cover 12 caused by contact between the locking part 121 and the side wall of the spring cover 12, which helps extend the service life of the spring cover 12, provides a more uniform pressure distribution for the spring cover 12, improves the stability of the spring cover 12 structure, and helps the locking part 121 avoid the sealing structure of the side wall of the spring cover 12, thus ensuring the sealing effect of the sealing structure of the spring cover 12.

[0037] In some embodiments, the spring-loaded mechanism 13 is movably mounted on the cover 11. When the spring-loaded mechanism 13 is in the locked position, the locking part 121 is locked to the cover 11. The spring-loaded mechanism 13 is adapted to move along the first direction Y and then along the second direction X to drive the locking part 121 to unlock from the cover 11. The first direction Y and the second direction X are distinct.

[0038] It should be noted that "the first direction Y and the second direction X are different" means that the first direction Y and the second direction X are not the same. For example, the first direction Y and the second direction X are not set parallel to each other. The first direction Y and the second direction X can intersect, or the first direction Y and the second direction X can be perpendicular to each other. The specific settings can be made according to the actual situation. The following explanation takes the first direction Y as the height direction of the container lid opening and closing device 100, the second direction X as the width direction of the container lid opening and closing device 100, and the first direction Y and the second direction X as perpendicular to each other.

[0039] Thus, the spring-loaded mechanism 13 can be moved to the locked position to ensure that the spring cover 12 can be locked to the cover body 11. Alternatively, the spring-loaded mechanism 13 can be moved to unlock the spring cover 12 from the cover body 11. The method of moving the spring-loaded mechanism 13 to unlock the spring cover 12 from the cover body 11 is simple, convenient for opening the spring cover 12, and also convenient for user operation.

[0040] For example, when it is necessary to close the spring cover 12, the locking part 121 can be locked to the cover body 11, and the spring latch mechanism 13 can be moved to the locking position along the first direction Y from the cover body 11 toward the spring cover 12. For example, the spring latch mechanism 13 can be moved along the first direction Y from the cover body 11 toward the spring cover 12. At this time, the spring latch mechanism 13 cannot drive the spring cover 12 to unlock from the cover body 11, thereby ensuring that the spring cover 12 can be in the closed state.

[0041] For example, when it is necessary to open the spring cover 12, the spring latch mechanism 13 can be moved along the first direction Y from the spring cover 12 toward the cover body 11, and then continue to move along the second direction X. For example, the spring latch mechanism 13 can be moved along the first direction Y from the spring cover 12 toward the cover body 11, and the spring latch mechanism 13 can be pressed to move along the second direction X, so that the spring latch mechanism 13 moves and drives the locking part 121 to unlock onto the cover body 11, thereby ensuring that the spring cover 12 can be in the open state.

[0042] Among them, such as Figure 3 As shown, the spring-loaded mechanism 13 can also be in the unlocked position. When in the unlocked position, the spring-loaded mechanism 13 moves along the first direction Y and disengages from the locked position. The spring-loaded mechanism 13 can be moved along the first direction Y from the spring cover 12 toward the cover body 11 to be in the unlocked position. When it is necessary to open the spring cover 12, the spring-loaded mechanism 13 in the unlocked position can be moved along the second direction X to move the spring-loaded mechanism 13 and drive the locking part 121 to unlock onto the cover body 11.

[0043] See Figures 4 to 7 In some embodiments, the snap-lock mechanism 13 includes an operating member 131 and a snap-lock assembly 132. The cover 11 includes a cover body 111 and a snap-lock mounting member 112 connected to each other. The operating member 131 is movably mounted on the cover body 111 along a first direction Y and is exposed outside the cover body 111. The snap-lock assembly 132 is mounted on the snap-lock mounting member 112. The operating member 131 is adapted to drive the snap-lock assembly 132 to move along a second direction X to drive the locking part 121 to unlock from the cover body 111.

[0044] Thus, by moving the operating element 131 toward the spring-loaded assembly 132 in the second direction X, the spring-loaded assembly 132 can be driven to move synchronously in the second direction X, thereby driving the locking part 121 to unlock onto the cover 11. The method by which the operating element 131 drives the spring-loaded assembly 132 and thus drives the locking part 121 to unlock onto the cover 11 is simple and facilitates user operation.

[0045] In some embodiments, the snap fastener assembly 132 includes an unlocking member 1321, and the operating member 131 is provided with a linkage part 1311. The linkage part 1311 is movably connected to the unlocking member 1321 along a first direction Y. When the snap fastener mechanism 13 is in the locked position, the linkage part 1311 restricts the movement of the unlocking member 1321 along a second direction X. The operating member 131 is adapted to drive the snap fastener assembly 132 to move along the second direction X through the linkage part 1311, so as to drive the locking part 121 to unlock onto the cover body 111.

[0046] Thus, the linkage between the operating member 131 and the spring buckle assembly 132 can be realized through the linkage part 1311, which makes it convenient for the user to drive the spring buckle assembly 132 to move through the operating member 131. It also allows the linkage part 1311 to restrict the movement of the unlocking member 1321 away from the operating member 131 along the second direction X when the spring buckle mechanism 13 is in the locked position. This helps to reduce the situation where the unlocking member 1321 moves away from the operating member 131 along the second direction X and drives the spring cover 12 to unlock onto the cover body 11 when the spring buckle mechanism 13 is in the locked position. This helps to ensure that the spring cover 12 can be locked onto the cover body 11.

[0047] The linkage part 1311 can be a snap-fit ​​structure. The snap-fit ​​structure is set at the end of the operating member 131 and snaps into the edge of the unlocking member 1321, thereby realizing the linkage between the operating member 131 and the spring buckle assembly 132, ensuring that the spring cover 12 can be locked into the cover body 11, and also helping to simplify the structure of the linkage part 1311 and facilitate the manufacturing of the operating member 131.

[0048] The linkage part 1311 can be two, and the two linkage parts 1311 are located at opposite ends of the operating member 131. The two linkage parts 1311 are respectively engaged with the two edges of the unlocking member 1321, thereby realizing the linkage between the operating member 131 and the two sides of the spring buckle assembly 132. It also helps the operating member 131 to restrict the movement of the spring buckle assembly 132 from both sides, thereby better ensuring that the spring cover 12 can be locked to the cover body 11.

[0049] In some embodiments, the cover body 111 is provided with a limiting part 1111, which is located on the movement path of the operating member 131 along the second direction X. When the snap-lock mechanism 13 is in the locked position, the limiting part 1111 restricts the movement of the operating member 131 along the second direction X, and the linkage part 1311 restricts the movement of the unlocking member 1321 along the second direction X.

[0050] Thus, when the spring-loaded mechanism 13 is in the locked position, the limiting part 1111 can restrict the movement of the operating member 131 along the second direction X, which helps to reduce the movement of the operating member 131 along the second direction X when the spring-loaded mechanism 13 is in the locked position, and helps to reduce the situation where the operating member 131 drives the spring cover 12 to unlock onto the cover body 11 when the spring-loaded mechanism 13 is in the locked position, thereby allowing the spring cover 12 to lock onto the cover body 11, and also helps the spring-loaded mechanism 13 to be maintained in the locked position more stably.

[0051] In some embodiments, the limiting part 1111 is also located on the movement path of the operating member 131 along the first direction Y.

[0052] Thus, the limiting part 1111 can also restrict the movement of the operating member 131 away from the first direction Y, which helps to reduce the situation where the operating member 131 continues to move along the first direction Y when the spring buckle mechanism 13 is in the locked position, helps to reduce the situation where the operating member 131 is loosened from the spring buckle mounting member 112 along the first direction Y, and helps the spring buckle mechanism 13 to be maintained in the locked position more stably.

[0053] See Figures 6 to 9 In some embodiments, the spring-loaded mounting member 112 is provided with a blocking part 1121, which is located on the moving path of the unlocking member 1321 along the second direction X. The unlocking member 1321 is provided with a blocking engagement part 1323, which is located between the blocking part 1121 and the inner wall 1123 of the spring-loaded mounting member 112.

[0054] Thus, the blocking part 1121 can restrict the movement of the unlocking member 1321 toward the operating member 131 in the second direction X, which helps to improve the stability of the unlocking member 1321 installed on the spring-loaded mounting member 112 and helps to reduce the situation where the unlocking member 1321 is loosened from the spring-loaded mounting member 112 when it moves toward the operating member 131 in the second direction X.

[0055] in, Figure 8 This describes the positions of the blocking engagement part 1323 and the blocking part 1121 when the spring-loaded mechanism 13 is in the locked position. Figure 9 The position of the blocking engagement part 1323 and the blocking part 1121 when the spring-loaded mechanism 13 is in the unlocked position.

[0056] The blocking part 1121 can be a protrusion, which is located on the side of the snap fastener 112 facing the unlocking part 1321. The blocking mating part 1323 can be a hook, which is located on the side of the unlocking part 1321 facing the snap fastener 112. The hook can hook the protrusion, thereby limiting the protrusion to the hook.

[0057] In some embodiments, the spring-loaded mounting member 112 is further provided with a guide portion 1122, which is connected to the blocking portion 1121 and the inner wall 1123 of the spring-loaded mounting member 112, and the blocking mating portion 1323 is movably connected to the guide portion 1122.

[0058] This helps guide the movement of the unlocking member 1321 in the second direction X, helps ensure that the unlocking member 1321 moves along the second direction X within the predetermined path, helps reduce the situation where the unlocking member 1321 deviates from the predetermined route, and the guide can provide a certain support force for the blocking mating part 1323, which helps reduce the shaking of the unlocking member 1321 in the second direction X and helps improve the stability of the unlocking member 1321 in the second direction X.

[0059] In some embodiments, the snap fastener assembly 132 further includes an elastic element 1322, one end of which is connected to the inner wall 1123 of the snap fastener mounting member 112, and the other end of which is connected to the unlocking member 1321. The elastic force of the elastic element 1322 is adapted to drive the unlocking member 1321 to move along the second direction X.

[0060] In this way, the force exerted by the user's operating component 131 to drive the unlocking component 1321 can overcome the elastic force of the elastic component 1322, so that the unlocking component 1321 moves along the second direction X toward the inner wall 1123 of the snap fastener 112. When the force acting on the operating component 131 disappears, for example when the user releases the operating component 131, the force acting on the unlocking component 1321 disappears simultaneously. The elastic force of the elastic component 1322 allows the unlocking component 1321 to move away from the inner wall 1123 of the snap fastener 112 along the second direction X, realizing the automatic reset of the unlocking component 1321. This eliminates the need for the user to manually drive the unlocking component 1321 to move, thus simplifying the user's operation process.

[0061] See Figure 5 , Figure 7 , Figure 10 and Figure 11 In some embodiments, the cover body 111 is provided with a guide opening 1112, and the locking part 121 passes through the guide opening 1112 and is limited to the cover body 111. The guide opening 1112 has a guide wall surface 1113, which is inclined along the first direction Y away from the guide opening 1112. When the spring buckle mechanism 13 drives the locking part 121 to unlock from the cover body 11, the locking part 121 is unlocked from the cover body 111 and slides through the guide wall surface 1113 to the guide opening 1112.

[0062] Thus, the guide wall 1113 can guide the movement of the locking part 121, which helps the locking part 121 to disengage from the cover body 111, thereby facilitating the opening of the spring cover 12. It also helps to reduce the friction between the locking part 121 and the cover body 111, and helps to reduce the possibility of damage due to excessive friction between the locking part 121 and the cover body 111.

[0063] The guide opening 1112 is spaced apart from the side wall of the cover body 111 to accommodate the position of the locking part 121. The guide wall 1113 may include a guide slope, a guide arc, or other guide surfaces. The specific configuration can be made according to the actual situation to facilitate the locking part 121 disengaging from the cover body 111.

[0064] See Figures 10 to 12In some embodiments, the spring-loaded buckle assembly 132 includes an unlocking member 1321. The unlocking member 1321 has an unlocking part 1324 on the side facing the locking part 121. The unlocking part 1324 is inclined toward the locking part 121 along the direction of the cover body 111 toward the spring cover 12. The locking part 121 is inclined toward the unlocking part 1324 along the direction of the cover body 111 toward the spring cover 12. The unlocking part 1324 is adapted to drive the locking part 121 to move along the second direction X so that the locking part 121 is unlocked from the cover body 111.

[0065] This allows the locking part 121 to adapt to the shape of the guide wall surface 1113, and the contact between the locking part 121 and the guide wall surface 1113 can be a surface-to-surface contact. This helps to increase the contact area between the locking part 121 and the guide wall surface 1113, which helps to improve the stability of the locking part 121 sliding on the guide wall surface 1113. It also helps to disperse the stress of the locking part 121 on the guide wall surface 1113, and helps to reduce the stress concentration at one location on the guide wall surface 1113, which could lead to wear on the guide wall surface 1113. In the event of wear, the unlocking part 1324 can be adapted to the shape of the locking part 121. The contact between the unlocking part 1324 and the locking part 121 can be a surface-to-surface contact, which helps to increase the contact area between the unlocking part 1324 and the locking part 121, improves the stability of the unlocking part 1324 driving the locking part 121 to move, and also helps to disperse the stress of the unlocking part 1324 on the locking part 121, which helps to reduce the situation where stress is concentrated at one position of the locking part 121, causing wear of the locking part 121.

[0066] In summary, the container lid opening and closing device 100 and container provided by this utility model have a spring-loaded cover 12 rotatably connected to a lid body 11, and a spring-loaded latch mechanism 13 movably mounted on the lid body 11. The spring-loaded cover 12 is provided with a locking part 121, which is spaced apart from the side wall of the spring-loaded cover 12. When the spring-loaded latch mechanism 13 is in the locked position, the locking part 121 is locked to the lid body 11. The spring-loaded latch mechanism 13 is adapted to move along a first direction Y and then along a second direction X to drive the locking part 121 to unlock from the lid body 11. The first direction Y and the second direction X are distinct. Thus, by moving the spring-loaded latch mechanism 13, the spring-loaded cover 12 can be locked to the lid body 11, and the spring-loaded cover 12 can also be unlocked from the lid body 11 by moving the spring-loaded latch mechanism 13. The spring-loaded mechanism 13 moves to unlock the spring cover 12 from the cover body 11, which is simple and convenient for opening the spring cover 12 and for user operation. Furthermore, the locking part 121 is spaced apart from the side wall of the spring cover 12, which helps reduce stress concentration on the side wall of the spring cover 12 caused by contact between the locking part 121 and the side wall, thus extending the service life of the spring cover 12. It also helps provide a more uniform pressure distribution on the spring cover 12, improving the structural stability of the spring cover 12. Additionally, the locking part 121 avoids the sealing structure of the side wall of the spring cover 12, ensuring the sealing effect of the sealing structure of the spring cover 12.
