Description

Technical Field

[0001] This application relates to the field of kitchen utensil technology, and more particularly to a lid and container lid. Background Technology

[0002] Cooking containers have lids with caps. A base within the cap is attached to the lid by riveting or screwing. A handle within the cap is attached to the base, allowing users to move the lid by gripping it, reducing the risk of burns or contamination. Currently, most caps have handles fixedly connected to the base, which takes up considerable space during packaging and transportation, resulting in higher packaging and shipping costs. Utility Model Content

[0003] In view of this, this application provides a cap and container cap to solve the problem that the handle in the cap occupies a large amount of space during packaging and transportation.

[0004] In a first aspect, embodiments of this application provide a cover, the cover comprising:

[0005] The base includes a receiving cavity;

[0006] A handle, which is detachably mounted to the base;

[0007] A locking element, which is detachably fitted onto the base to adjust the diameter of the receiving cavity;

[0008] The handle includes a connecting portion, at least a portion of which is located within the receiving cavity. When the locking member is locked, the inner wall of the receiving cavity abuts against the connecting portion. When the locking member is unlocked, there is a gap between the inner wall of the receiving cavity and the connecting portion, allowing the handle to move relative to the base.

[0009] At least part of the connecting part is located within the receiving cavity. When the locking element is tightened, the diameter of the receiving cavity decreases, and the inner wall of the receiving cavity clamps the connecting part located within the receiving cavity. There is significant friction between the connecting part and the inner wall of the receiving cavity, which restricts the relative position of the handle and the base. When the container lid is placed upright on a table, the handle can support the lid, improving its stability. When the locking element is unlocked, the diameter of the receiving cavity increases, the friction between the connecting part and the inner wall of the receiving cavity decreases, and there may even be a gap between the inner wall of the receiving cavity and the connecting part. The connecting part can move within the receiving cavity, thereby adjusting the angle between the handle and the base, allowing the lid to be used with container lids of different sizes or shapes, thus increasing the lid's versatility. When the locking element disengages from the base, the connecting part can be pulled out of the receiving cavity, separating the handle from the base. This reduces the space occupied by the lid during packaging and transportation, lowering packaging and transportation costs. Furthermore, by adjusting the angle between the handle and the base during packaging and transportation, the height of the container lid can be reduced, further reducing the space occupied by the lid and lowering packaging and transportation costs.

[0010] In one possible embodiment, the connection includes a mounting head that is spherical and located within the receiving cavity.

[0011] When the locking mechanism is unlocked, the spherical mounting head can rotate in multiple directions within the receiving cavity. This allows the handle to rotate about the base's axis, adjusting the contact position between the container lid and the table surface when the lid is placed upright, thus enabling the cap head to be used with lids of different shapes. It also allows adjustment of the angle between the handle and the base's axis, making the cap head suitable for lids of different sizes. Regardless of the handle's position, after the locking mechanism is engaged, the contact area between the inner wall of the receiving cavity and the mounting head remains unchanged, effectively limiting the relative position of the handle and the base.

[0012] In one possible embodiment, the connecting portion includes a connecting rod with a diameter smaller than that of the mounting head and connected to the mounting head; the handle includes a grip portion, with one end of the connecting rod away from the mounting head protruding from the receiving cavity and connected to the grip portion.

[0013] The user can grip the handle using the grip part, which abuts against the tabletop when the container lid is placed upright, supporting the lid. The connecting rod protrudes from the receiving cavity on the side furthest from the mounting head. The mounting head and grip part are connected via the connecting rod, increasing the distance between the grip part and the locking element or base. This reduces the possibility of interference between the grip part and the locking element or base as the grip part rotates with the mounting head, and improves the handle's adjustability. The diameter of the connecting rod is smaller than the diameter of the mounting head. This reduces the possibility of interference between the connecting rod and the opening of the receiving cavity as the mounting head rotates, and increases the range of rotation the mounting head can make within the receiving cavity.

[0014] In one possible embodiment, the base includes at least two grippers, which are spaced apart and enclose the receiving cavity.

[0015] At least two grippers are spaced apart, allowing them to deform towards or away from each other. During the locking process, the locking member pushes the at least two grippers to deform towards each other, reducing the diameter of the receiving cavity and allowing the inner wall of the receiving cavity to clamp the mounting head. During the unlocking process, the locking member releases the force on the grippers, and under the action of the grippers' own elasticity, the at least two grippers can deform towards each other, increasing the gap between adjacent grippers and thus increasing the diameter of the receiving cavity. This reduces the friction between the inner wall of the receiving cavity and the mounting head, and may even create a gap between the inner wall of the receiving cavity and the mounting head, allowing the mounting head to rotate within the receiving cavity.

[0016] In one possible embodiment, at least two of the grippers are arranged symmetrically.

[0017] At least two grippers form a receiving cavity, and the inner wall of the receiving cavity is formed by the side walls of at least two grippers. When the locking element is locked, at least two grippers clamp the mounting head. The friction between the side walls of the grippers and the mounting head limits the relative position of the handle and the base. The at least two grippers are arranged axially symmetrically, so that the force applied by the at least two grippers to the mounting head is more uniform, which can improve the stability of the handle after the locking element is locked.

[0018] In one possible embodiment, the gripper includes a bent portion located at the end of the gripper facing the handle, and the bent portions of at least two of the grippers are bent toward each other; when the locking member is locked, the distance between the bent portions of at least two of the grippers is less than the diameter of the mounting head and greater than the diameter of the connecting rod.

[0019] When the locking element is engaged, the distance between the bent portions of at least two grippers is less than the diameter of the mounting head, reducing the possibility of the mounting head disengaging from the receiving cavity after the locking element is engaged. When the locking element is engaged, the distance between the bent portions of at least two grippers is greater than the diameter of the connecting rod, allowing the connecting rod room to move between at least two bent portions, reducing the possibility of interference between the connecting rod and the bent portions when adjusting the angle between the handle and the base.

[0020] In one possible embodiment, the gripper is provided with an external thread on the side away from the receiving cavity, the locking member is provided with an internal thread, and the gripper and the locking member are threadedly engaged.

[0021] The jaws and the locking element are threaded together. By rotating the locking element, the locking element can be moved along the axial direction of the base, thereby adjusting the position of the locking element on the jaws and changing the distance between at least two jaws.

[0022] In one possible embodiment, the outer diameter of at least two of the grippers gradually increases along the direction from the handle to the base.

[0023] When the locking element is rotated, moving it along the direction from the handle towards the base, it moves from a position with a smaller outer diameter of at least two jaws to a position with a larger outer diameter. This causes the locking element to push the jaws closer together, reducing the diameter of the receiving cavity and clamping the mounting head, thus fixing the handle to the base. When the locking element is rotated in the opposite direction, moving it along the direction from the base towards the handle, it moves from a position with a larger outer diameter of at least two jaws to a position with a smaller outer diameter. This gradually releases the force exerted by the locking element on the jaws, causing them to deform away from each other under their own elastic force. This increases the diameter of the receiving cavity, allowing the handle to rotate relative to the base.

[0024] In one possible embodiment, the inner diameter of the locking member gradually increases along the direction from the handle to the base.

[0025] When the locking element is rotated so that it moves in the direction from the handle to the base, the inner diameter of the locking element, which is fitted onto at least two grippers, gradually decreases. This causes the grippers to deform in a direction closer to each other, gradually reducing the diameter of the receiving cavity and clamping the mounting head to fix the handle to the base. When the locking element is rotated in the opposite direction so that it moves in the direction from the base to the handle, the inner diameter of the locking element, which is fitted onto at least two grippers, gradually increases. Under the action of the grippers' own elasticity, the grippers deform in a direction further away from each other, gradually reducing the diameter of the receiving cavity. This allows the mounting head to rotate within the receiving cavity to adjust the angle between the handle and the base.

[0026] Secondly, this application provides a container lid, which includes a lid body and a lid head. The lid head is fixedly installed on the lid body. The lid head is any of the lid heads described above, and therefore has the technical effects described above, which will not be repeated here.

[0027] This application relates to a cap and container cap. The cap includes a base, a handle, and a locking element, both of which are detachably mounted on the base. The base includes a receiving cavity, and the locking element is sleeved on the base, allowing adjustment of the diameter of the receiving cavity. The handle includes a connecting portion, at least a portion of which is located within the receiving cavity. When the locking element is locked, the diameter of the receiving cavity decreases, and the inner wall of the receiving cavity abuts against the connecting portion, creating significant friction between the connecting portion and the inner wall of the receiving cavity to limit the relative position of the handle and the base. When the locking element is unlocked, the diameter of the receiving cavity increases, creating a gap between the inner wall of the receiving cavity and the connecting portion, allowing the connecting portion to rotate within the receiving cavity. This, in turn, allows the handle to move relative to the base, facilitating adjustment of the angle between the handle and the base. Attached Figure Description

[0048] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0049] like Figure 1 As shown, this application embodiment provides a container lid, including a lid head 100 and a lid body 200. The lid head 100 is installed on the lid body 200. The lid head 100 includes a base 1 and a handle 2. The handle 2 is detachably installed on the base 1.

[0050] Users can pick up the container lid using the handle 2. When the container lid is placed on the countertop, the end of the handle 2 away from the base 1 and the edge of the lid 200 abut against the countertop, allowing the container lid to stand upright on the countertop and reducing the possibility of the container lid contaminating the countertop.

[0051] like Figure 2 , Figure 3 and Figure 4 As shown, this application embodiment provides a cap 100 applied to the aforementioned container cap. The cap 100 includes a base 1, a handle 2, and a locking member 3. Both the handle 2 and the locking member 3 are detachably mounted on the base 1. The base 1 includes a receiving cavity 11, and the locking member 3 is sleeved on the base 1, allowing adjustment of the diameter of the receiving cavity 11. The handle 2 includes a connecting portion 21, at least a portion of which is located within the receiving cavity 11. When the locking member 3 is locked, the inner wall of the receiving cavity 11 abuts against the connecting portion 21 to limit the relative position of the handle 2 and the base 1. When the locking member 3 is unlocked, a gap exists between the inner wall of the receiving cavity 11 and the connecting portion 21, allowing the handle 2 to move relative to the base 1 to adjust the angle between the handle 2 and the base 1.

[0052] At least a portion of the connecting part 21 is located within the receiving cavity 11. When the locking member 3 is locked, the diameter of the receiving cavity 11 decreases, and the inner wall of the receiving cavity 11 clamps the connecting part 21 located within the receiving cavity 11. There is a large frictional force between the connecting part 21 and the inner wall of the receiving cavity 11, which can limit the relative position of the handle 2 and the base 1. When the container lid is placed upright on the table, the handle 2 can support the lid 200, improving the stability of the container lid when it is placed upright. When the locking member 3 is unlocked, the diameter of the receiving cavity 11 increases, the frictional force between the connecting part 21 and the inner wall of the receiving cavity 11 decreases, and there may even be a gap between the inner wall of the receiving cavity 11 and the connecting part 21. The connecting part 21 can move within the receiving cavity 11, thereby adjusting the angle between the handle 2 and the base 1, so that the cap 100 can be used for caps 200 of different sizes or shapes, thereby increasing the application range of the cap 100. When the locking element 3 disengages from the base 1, the connecting part 21 can be pulled out from the receiving cavity 11, separating the handle 2 from the base 1. This reduces the space occupied by the cap 100 during packaging and transportation, thus lowering packaging and transportation costs. Furthermore, during packaging and transportation, the angle between the handle 2 and the base 1 can be adjusted to reduce the distance between the handle 2 and the cap 200, thereby reducing the space occupied by the container cap and lowering packaging and transportation costs.

[0053] like Figure 4 As shown, in one possible embodiment, the connecting part 21 includes a mounting head 211, which is spherical and located within the receiving cavity 11.

[0054] When the locking element 3 is unlocked, the spherical mounting head 211 can rotate in multiple directions within the receiving cavity 11. This allows the handle 2 to rotate about the axis of the base 1, thereby adjusting the relative position between the handle 2 and the lid 200, and adjusting the contact position between the lid 200 and the table surface when the container lid is placed upright, so that the lid head 100 can be used with lids 200 of different shapes. It also allows adjustment of the angle between the axes of the handle 2 and the base 1, so that the lid head 100 can be used with lids 200 of different sizes. When the handle 2 is in different states, after the locking element 3 is locked, the contact area between the inner wall of the receiving cavity 11 and the mounting head 211 will not change, thus restricting the relative position between the handle 2 and the base 1.

[0055] like Figure 4 As shown, in one possible embodiment, the handle 2 includes a grip portion 22 extending in a direction perpendicular to the connecting portion 21. The user can grip the handle 2 using the grip portion 22. When the container lid is placed upright on a table, the grip portion 22 abuts against the table to support the lid. The connecting portion 21 includes a connecting rod 212, one end of which is connected to the mounting head 211, and the other end is connected to the grip portion 22. The diameter of the connecting rod 212 is smaller than the diameter of the mounting head 211, and the end of the connecting rod 212 away from the mounting head 211 protrudes from the receiving cavity 11.

[0056] The angle between the grip 22 and the base 1 is adjusted by rotating the mounting head 211 within the receiving cavity 11, allowing the cap 100 to be adapted to caps 200 of different shapes and sizes. The connecting rod 212 protrudes from the receiving cavity 11 on the side away from the mounting head 211. The mounting head 211 and the grip 22 are connected by the connecting rod 212, increasing the distance between the grip 22 and the locking member 3 or the base 1. As the grip 22 rotates with the mounting head 211, the possibility of interference between the grip 22 and the locking member 3 or the base 1 is reduced, and the adjustable range of the handle 2 is improved.

[0057] The receiving cavity 11 has an opening on the side facing the gripping part 22. The connecting rod 212 can protrude from the receiving cavity 11 through the opening. The diameter of the connecting rod 212 is smaller than the diameter of the mounting head 211. When the connecting rod 212 rotates with the mounting head 211, the possibility of interference between the connecting rod 212 and the opening can be reduced, and the range of rotation of the mounting head 211 within the receiving cavity 11 can be increased.

[0058] like Figure 5 As shown, in one possible embodiment, the base 1 includes at least two grippers 12, which together form a receiving cavity 11. The at least two grippers 12 are spaced apart, creating a gap between adjacent grippers 12.

[0059] At least two grippers 12 can deform in a direction that approaches or moves away from each other. During the locking process of the locking member 3, the locking member 3 pushes at least two grippers 12 to deform in a direction that approaches each other, so that the gap between adjacent grippers 12 is reduced, thereby reducing the diameter of the receiving cavity 11, so that the inner wall of the receiving cavity 11 can clamp the mounting head 211. During the unlocking process of the locking member 3, the locking member 3 releases the force on the grippers. Under the action of the elastic force of the grippers 12 themselves, at least two grippers 12 can deform in a direction that moves away from each other, so that the gap between adjacent grippers 12 is increased, thereby increasing the diameter of the receiving cavity 11, reducing the friction between the inner wall of the receiving cavity 11 and the mounting head 211, or even creating a gap between the inner wall of the receiving cavity 11 and the mounting head 211, so that the mounting head 211 can rotate in the receiving cavity 11.

[0060] like Figure 5 As shown, in one possible embodiment, at least two grippers 12 are arranged around the axis of the base 1, and at least two grippers 12 are arranged axially symmetrically.

[0061] At least two grippers 12 form a receiving cavity 11. Therefore, the inner wall of the receiving cavity 11 is formed by the side walls of at least two grippers 12. When the locking member 3 is locked, at least two grippers 12 clamp the mounting head 211. The friction between the side walls of the grippers 12 and the mounting head 211 limits the relative position of the handle 2 and the base 1. The at least two grippers 12 are arranged axially symmetrically, so that the force applied by the at least two grippers 12 to the mounting head 211 is more uniform, which can improve the stability of the handle 2 after the locking member 3 is locked.

[0062] In the radial section of the base 1, the section facing the receiving cavity 11 of the gripper 12 is arc-shaped, which can increase the contact area between the gripper 12 and the surface of the spherical mounting head 211, thereby improving the stability when the gripper 12 clamps the mounting head 211. When the diameter of the receiving cavity 11 is constant, the difficulty of elastic deformation of the gripper 12 increases with the increase of the arc length of the gripper 12. Therefore, the base 1 may include four or more spaced grippers 12 to reduce the arc length of a single gripper 12, reduce the difficulty of deformation of the gripper 12, and facilitate the switching of the locking member 3 between the locked and unlocked states.

[0063] like Figure 5 As shown, in one possible embodiment, the gripper 12 includes a bent portion 121 located at the end of the gripper 12 facing the handle 2. At least two bent portions 121 form an opening. The bent portions 121 in the at least two grippers 12 are bent toward each other, so that the cross-sectional area of ​​the opening is smaller than the cross-sectional area of ​​the receiving cavity 11.

[0064] When the locking member 3 is locked, the distance between the bent portions 121 of at least two grippers 12 is less than the diameter of the mounting head 211, making the diameter of the opening smaller than the diameter of the mounting head 211. This reduces the possibility of the mounting head 211 disengaging from the receiving cavity 11 during use of the cover 100. When the locking member 3 is locked, the distance between the bent portions 121 of at least two grippers 12 is greater than the diameter of the connecting rod 212, making the diameter of the opening larger than the diameter of the connecting rod 212. The connecting rod 212 has room to move at the opening, reducing the possibility of interference between the connecting rod 212 and the bent portion 121 when adjusting the angle between the handle 2 and the base 1.

[0065] In one possible embodiment, when the locking member 3 is unlocked, the distance between the bent portions 121 of at least two grippers 12 is less than the diameter of the mounting head 211, so that the diameter of the opening is less than the diameter of the mounting head 211. When adjusting the angle between the handle 2 and the base 1, the possibility of the mounting head 211 disengaging from the receiving cavity 11 can be reduced, thus improving the reliability of the adjustment process.

[0066] When the locking member 3 is not fitted onto the gripper 12, at least two grippers 12 can deform in directions away from each other. For example... Figure 5As shown, the bent part 121 has a guide surface 122 on the side facing the opening, which gradually increases the cross-sectional area of ​​the opening along the direction pointing to the receiving cavity 11. When the handle 2 is installed on the base 1, the mounting head 211 can extend into the receiving cavity 11 along the guide surface 122, reducing the difficulty of installing the handle 2 on the base 1.

[0067] like Figure 4 and Figure 5 As shown, in one possible embodiment, the locking member 3 is sleeved on the outside of at least two grippers 12. The grippers 12 are provided with external threads on the side away from the receiving cavity 11, and the locking member 3 is provided with internal threads, so that the grippers 12 and the locking member 3 are threadedly engaged.

[0068] The jaw 12 and the locking member 3 are threaded together. By rotating the locking member 3, the locking member 3 can move along the axial direction of the base 1, thereby adjusting the position of the locking member 3 on the jaw 12 and changing the distance between at least two jaws 12.

[0069] like Figure 4 As shown, in one possible embodiment, the cross-section of the locking member 3 along its radial direction can be a polygon, preferably a regular hexagon, etc., so that the user can manually or by means of a tool rotate the locking member 3, thereby facilitating the adjustment of the relative position of the handle 2 and the base 1.

[0070] In one possible embodiment, along the direction from the handle 2 to the base 1, the outer diameter of at least two grippers 12 gradually increases, and the inner diameter of the locking member 3 is the same.

[0071] When the locking member 3 is rotated so that it moves in the direction from the handle 2 toward the base 1, the locking member 3 moves from the position with the smaller outer diameter of the at least two grippers 12 to the position with the larger outer diameter. The locking member 3 will push the at least two grippers 12 to deform in a direction closer to each other, reducing the diameter of the receiving cavity 11, thereby clamping the mounting head 211 and fixing the handle 2 to the base 1. When the locking member 3 is rotated in the opposite direction so that it moves in the direction from the base 1 toward the handle 2, the locking member 3 moves from the position with the larger outer diameter of the at least two grippers 12 to the position with the smaller outer diameter. This will gradually release the force of the locking member 3 on the grippers 12, causing the grippers 12 to deform in a direction away from each other under the action of their own elasticity. The diameter of the receiving cavity 11 will increase, allowing the handle 2 to rotate relative to the base 1.

[0072] In one possible embodiment, the inner diameter of the locking member 3 gradually increases along the direction from the handle 2 to the base 1, and the outer diameters of at least the two grippers 12 are the same.

[0073] When the locking member 3 is rotated so that it moves in the direction from the handle 2 to the base 1, the inner diameter of the locking member 3, which is fitted onto at least two grippers 12, gradually decreases. This causes the grippers 12 to deform in a direction closer to each other, gradually reducing the diameter of the receiving cavity 11 and clamping the mounting head 211, thus fixing the handle 2 to the base 1. When the locking member 3 is rotated in the opposite direction so that it moves in the direction from the base 1 to the handle 2, the inner diameter of the locking member 3, which is fitted onto at least two grippers 12, gradually increases. Under the action of the grippers 12's own elasticity, the grippers 12 deform in a direction further away from each other, gradually reducing the diameter of the receiving cavity 11. This allows the mounting head 211 to rotate within the receiving cavity 11, thereby adjusting the angle between the handle 2 and the base 1.

[0074] In one possible embodiment, as the inner diameter of the locking member 3 gradually increases along the direction from the handle 2 to the base 1, the outer diameter of at least two grippers 12 also gradually increases. When the locking member 3 moves relative to the grippers 12 along the direction from the handle 2 to the base 1 or the direction from the base 1 to the handle 2, the range of change in the gap between at least two grippers 12 can be increased, thereby reducing the number of rotations of the locking member 3 and making it easier for the locking member 3 to switch between the locked and unlocked states.
