Description

Technical Field

[0001] This utility model belongs to the field of cup lid technology, and in particular relates to a cup lid. Background Technology

[0002] There is a type of flip-top cup lid, which typically includes a lid body and a flip cover. The flip cover is rotatably connected to the lid body. By driving the flip cover to rotate, the drinking opening on the lid body, which was originally closed by the flip cover, is exposed, allowing the user to drink water, beverages, etc. from the drinking opening.

[0003] Existing flip lids typically use magnetic attraction to keep them open or closed. Specifically, magnets are placed on both the flip lid and the lid body. When the lid is flipped to the open position, a magnet on the flip lid attracts a magnet on the lid body to keep it stationary; when the lid is rotated to the closed position, a magnet on the flip lid attracts a magnet on the lid body to keep it stationary. However, using magnets results in excessively high costs for the lids. Utility Model Content

Detailed Implementation

[0041] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0042] To keep the drawings concise, only the parts relevant to this invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0043] The cup lid includes a lid body 1 and a flip lid 2. The lid body 1 has a drinking spout 4. The flip lid 2 is rotatably connected to the lid body 1. The flip lid 2 is in the open state and the closed state at the two ends of its rotation stroke, respectively. When the lid is in the open state, the drinking spout 4 is exposed, allowing fluid to pass through the drinking spout 4; when the lid is in the closed state, the flip lid 2 closes the drinking spout 4, preventing fluid from passing through the drinking spout 4.

[0044] The flip cover 2 includes a flip cover body 10 and at least one elastic arm 11. One end of the elastic arm 11 is connected to the flip cover body 10, and the other end is pivotally connected to the cover body 1. That is, the flip cover 2 achieves rotation relative to the cover body 1 through the pivotal connection between the elastic arm 11 and the cover body 1.

[0045] The elastic arm 11 is elastically flipped to connect the cup lid in the open state and the cup lid in the closed state. That is, the flip lid 2 can switch between the cup lid in the open state and the cup lid in the closed state by flipping the elastic arm 11.

[0046] The flip cover 2 can be held in a certain state when flipped without external force. Specifically, the space traversed by the elastic arm 11 during the flipping process is defined as the swing trajectory space; the cover body 1 is provided with at least one blocking part 8, which is configured to at least partially extend into the swing trajectory space; when flipped without external force, the flip cover 2 can be held in the open state of the cup lid or in the state of abutting against the blocking part 8 under its own weight. When the cup lid is closed, in order to ensure sealing, other methods are generally used to further ensure that the position of the flip cover 2 is fixed, and this utility model does not limit such other methods.

[0047] When the user applies force to rotate the flip cover 2, the elastic arm 11 deforms elastically upon encountering the blocking part 8 due to the force applied by the user, allowing it to continue rotating past the blocking part 8. Therefore, at the user's will (i.e., when the user applies force to rotate the flip cover 2), the flip cover 2 can rotate from the closed position to the open position, or vice versa. If the user does not apply external force to the flip cover 2 (in the non-closed position), when the flip cover 2 rotates freely, it will collide with the blocking part 8 upon reaching it, preventing it from passing through. Furthermore, under its own weight, the flip cover 2 will flip and come into contact with other components, such as against the blocking part 8.

[0048] Thus, when the user turns the flip cover 2 to open the drinking spout 4, they only need to rotate the flip cover 2 past the blocking part 8 and then release the flip cover 2 before drinking from the drinking spout 4 (generally, the lid is used in conjunction with the cup body 16 to form a container). At this time, the flip cover 2 will abut against the blocking part 8 under its own weight but cannot pass through the blocking part 8. The blocking part 8 helps to prevent the flip cover 2 from rebounding and hitting the user due to gravity when drinking from the drinking spout 4. Moreover, the lid does not require magnets, resulting in lower overall production costs.

[0049] The cup lid will be further described below with some examples.

[0050] Example 1

[0051] See Figures 1 to 10This embodiment provides a cup lid, including a lid body 1 and a flip lid 2. The lid body 1 has a receiving groove 3, and the receiving groove 3 has a drinking spout 4 and an air hole 5; the flip lid 2 is rotatably connected to the lid body 1. The flip lid 2 includes a flip lid body 10 and at least one elastic arm 11. One end of the elastic arm 11 is connected to the flip lid body 10, and the other end is pivotally connected to the receiving groove 3. The elastic arm 11 is elastically flipped to connect the cup lid in an open state and a closed state. The flip lid 2 can be held in a certain state when there is no external force to flip it. Specifically, when the cup lid is closed, the flip lid 2 closes the drinking spout 4 and the air hole 5, and when the cup lid is open, the drinking spout 4 and the air hole 5 are exposed.

[0052] The space traversed by the elastic arm 11 during the flipping process is defined as the swing trajectory space. The lid body 1 is provided with at least one blocking part 8, which is configured to at least partially extend into the swing trajectory space; specifically, the blocking part 8 at least partially protrudes into the receiving groove 3. When the flip lid 2 is not flipped by external force, it can be held in the cup lid opening state or held in the state of abutting against the blocking part 8 under its own weight.

[0053] The lid body 1 is provided with a first rotating part, and the elastic arm 11 is provided with a corresponding second rotating part. One of the first rotating part and the second rotating part is a rotating shaft 7, and the other is a rotating shaft hole 6. The rotating shaft 7 is inserted into and rotatably connected to the rotating shaft hole 6. Specifically, in this embodiment, the first rotating part is the rotating shaft hole 6, and the second rotating part is the rotating shaft 7. When the elastic arm 11 encounters the blocking part 8 during the flipping process, it can undergo elastic deformation under the action of external force to pass through the blocking part 8. When the elastic arm 11 undergoes elastic deformation to pass through the blocking part 8, there may be no axial displacement between the rotating shaft 7 and the rotating shaft hole 6, or there may be axial displacement; however, when there is axial displacement between the rotating shaft 7 and the rotating shaft hole 6, the rotating shaft 7 will never disengage from the rotating shaft hole 6 during the rotation process of the flip lid 2 switching between the open and closed states of the lid.

[0054] Preferably, the bottom surfaces of the blocking part 8 and the receiving groove 3 are located on both sides of the portion of the inner wall of the receiving groove 3 that is pivotally connected to the elastic arm 11, that is, the blocking part 8 is located on the side of the rotating shaft hole 6 that is relatively far away from the bottom surface of the receiving groove 3.

[0055] Preferably, in this embodiment, the flip cover 2 includes two elastic arms 11, which are pivotally connected to two opposing inner sidewalls of the receiving groove 3; the cover body 1 is provided with blocking parts 8 corresponding to the two elastic arms 11 respectively.

[0056] Preferably, the surface of the elastic arm 11 that contacts the blocking part 8 is a smooth curved surface, and the surface of the blocking part 8 that contacts the elastic arm 11 is a smooth curved surface. For example... Figure 7As shown, the part of the elastic arm 11 that interferes with the blocking part 8 during the flipping process is the mating section 13 of the elastic arm 11. The side of the mating section 13 of the elastic arm 11 facing the blocking part 88 is an arc surface (i.e., the arc surface is an arc within a cross-section perpendicular to the length direction of the elastic arm 11). For ease of distinction, this arc surface is referred to as the first arc surface 12. For example... Figure 6 As shown, the end face of the portion of the blocking part 8 that protrudes from the inner wall of the receiving groove 3 towards the inner wall of the receiving groove 3 is an arc surface. For easy distinction, this arc surface is called the second arc surface 9. Furthermore, along the length of the receiving groove 3, the middle of the second arc surface 9 protrudes further from the inner wall of the receiving groove 3, and the length protruding from the inner wall of the receiving groove 3 gradually decreases as it moves to both sides. The arrangement of the first arc surface 12 and the second arc surface 9 makes the elastic arm 11 move more smoothly and with less effort when passing through the blocking part 8. Moreover, if a flat surface is used, the elastic arm 11 may stop at the blocking part 8 without moving, but the arc surface prevents the elastic arm 11 from stopping at the blocking part 8.

[0057] Furthermore, the inner wall of the receiving groove 3 is provided with a positioning hole 14, and the outer wall of the flip cover 2 is provided with a corresponding positioning protrusion 15. When the flip cover 2 is in the closed position of the cup lid, the positioning protrusion 15 is engaged in the positioning hole 14, thereby realizing the positioning of the flip cover 2 when the cup lid is closed. The cooperation between the positioning protrusion 15 and the positioning hole 14 also has the function of fixing the flip cover 2 in the position when the cup lid is closed.

[0058] The cup lid provided in this embodiment can be fitted with the cup body 16 to form a container. Specifically, the cup body 16 has a cup opening, and the cup lid is connected to the cup opening so that the cup lid and the cup body 16 fit together to form a sealed chamber, which can be used to store liquids such as water and beverages.

[0059] Example 2

[0060] See Figures 11 to 20 This embodiment provides a cup lid, including a lid body 1 and a flip lid 2. The lid body 1 has a receiving groove 3, and the receiving groove 3 has a drinking spout 4 and an air hole 5; the flip lid 2 is rotatably connected to the lid body 1. The flip lid 2 includes a flip lid body 10 and at least one elastic arm 11. One end of the elastic arm 11 is connected to the flip lid body 10, and the other end is pivotally connected to the receiving groove 3. The elastic arm 11 is elastically flipped to connect the cup lid in an open state and a closed state. The flip lid 2 can be held in a certain state when there is no external force to flip it. Specifically, when the cup lid is closed, the flip lid 2 closes the drinking spout 4 and the air hole 5, and when the cup lid is open, the drinking spout 4 and the air hole 5 are exposed.

[0061] The space traversed by the elastic arm 11 during the flipping process is defined as the swing trajectory space. The lid body 1 is provided with at least one blocking part 8, which is configured to extend at least partially into the swing trajectory space. When the lid 2 is not flipped by external force, it can be held in the open state of the lid or in the state of abutting against the blocking part 8 under its own weight.

[0062] Specifically, in this embodiment, the elastic arm 11 includes an arm body 17 and a protrusion 18 protruding from the arm body 17. One end of the arm body 17 is connected to the flip cover body 10, and the other end is pivotally connected to the receiving groove 3. Preferably, the protrusion 18 is located near the end of the arm body 17 that is pivotally connected to the receiving groove 3.

[0063] A recessed movable groove 19 for accommodating the protrusion 18 is formed on the inner wall of the receiving groove 3. A portion of the inner wall of the movable groove 19 protrudes 18 to form a blocking portion 8. The blocking portion 8 divides the movable groove 19 into a closed area 20 and an open area 21. When the cup lid is closed, the protrusion 18 falls into the closed area 20; when the cup lid is open, the protrusion 18 falls into the open area 21. Furthermore, the movable groove 19 is connected to the end face of the lid body 1 (here, the end face of the lid body 1 refers to the end face on the lid body 1 where the receiving groove 3 is provided).

[0064] The lid body 1 is provided with a first rotating part, and the elastic arm 11 is provided with a corresponding second rotating part. One of the first rotating part and the second rotating part is a rotating shaft 7, and the other is a rotating shaft hole 6. The rotating shaft 7 is inserted into and rotatably connected to the rotating shaft hole 6. Specifically, in this embodiment, the first rotating part is the rotating shaft hole 6, and the second rotating part is the rotating shaft 7. When the elastic arm 11 encounters the blocking part 8 during the flipping process, it can undergo elastic deformation under the action of external force to pass through the blocking part 8. When the elastic arm 11 undergoes elastic deformation to pass through the blocking part 8, there may be no axial displacement between the rotating shaft 7 and the rotating shaft hole 6, or there may be axial displacement; however, when there is axial displacement between the rotating shaft 7 and the rotating shaft hole 6, the rotating shaft 7 will never disengage from the rotating shaft hole 6 during the rotation process of the flip lid 2 switching between the open and closed states of the lid.

[0065] Preferably, the bottom surfaces of the blocking part 8 and the receiving groove 3 are located on both sides of the portion of the inner wall of the receiving groove 3 that is pivotally connected to the elastic arm 11, that is, the blocking part 8 is located on the side of the rotating shaft hole 6 that is relatively far away from the bottom surface of the receiving groove 3.

[0066] Preferably, in this embodiment, the flip cover 2 includes two elastic arms 11, which are pivotally connected to two opposing inner sidewalls of the receiving groove 3; the cover body 1 is provided with blocking parts 8 corresponding to the two elastic arms 11 respectively.

[0067] Preferably, the end of the protrusion 18 is designed as a rounded head; the inner wall of the movable groove 19 forming the blocking part 8 protrudes in the form of a smooth curved surface, with a large protrusion in the middle and gradually decreasing towards both sides, forming an arc surface. Both of these designs make the process of the protrusion 18 passing through the blocking part 8 smoother and less strenuous. If the contact point between the protrusion 18 and the blocking part 8 has a plane or the surface of the blocking part 8 has a plane, the flip cover 2 may stop in the state where the protrusion 18 is in contact with the blocking part 8. However, the rounded head and arc surface designs prevent the protrusion 18 from stopping at the blocking part 8.

[0068] Furthermore, the inner wall of the receiving groove 3 is provided with a positioning hole 14, and the outer wall of the flip cover 2 is provided with a corresponding positioning protrusion 15. When the flip cover 2 is in the closed position of the cup lid, the positioning protrusion 15 is engaged in the positioning hole 14, thereby realizing the positioning of the flip cover 2 when the cup lid is closed. The cooperation between the positioning protrusion 15 and the positioning hole 14 also has the function of fixing the flip cover 2 in the position when the cup lid is closed.

[0069] The cup lid provided in this embodiment can be fitted with the cup body 16 to form a container. Specifically, the cup body 16 has a cup opening, and the cup lid is connected to the cup opening so that the cup lid and the cup body 16 fit together to form a sealed chamber, which can be used to store liquids such as water and beverages.

[0070] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
