Description

Technical Field

[0001] This application relates to the field of everyday consumer goods technology, and in particular to a cup lid and a water cup. Background Technology

[0002] A water cup typically consists of a cup body and a lid, with the lid attached to the mouth of the cup body to close it. The lid may have a spout, allowing the user to drink from the liquid inside the cup. The spout can be stored in the lid when not in use. To prevent accidental opening and leakage, the spout needs to be locked in the stored position. Current technologies have complex locking mechanisms for spouts, which negatively impact the user experience. Utility Model Content

[0003] This application provides a cup lid and a water cup to simplify the locking structure of the spout and improve the user experience of the water cup.

[0004] The first aspect of this application provides a cup lid, which includes:

[0005] The lid has a receiving groove at the top and a drinking spout at the bottom of the receiving groove;

[0006] A mouthpiece assembly is disposed within the receiving groove and pivotally connected to the cover. The mouthpiece assembly has an open state that communicates with the drinking opening, or a closed state that is housed in the receiving groove and blocks the drinking opening.

[0007] The receiving groove is provided with a locking structure along its own central surface to lock the suction nozzle assembly in the receiving groove when the suction nozzle assembly is in the locked state.

[0008] The cup lid provided in this application includes a lid body and a spout assembly. The top of the lid body has a receiving groove, and the bottom of the receiving groove has a drinking spout. The spout assembly is disposed within the receiving groove and is pivotally connected to the lid body. The spout assembly has an open state that connects to the drinking spout, or a locked state that is stored in the receiving groove and blocks the drinking spout. The receiving groove has a locking structure along its central surface to lock the spout assembly within the receiving groove when it is in the locked state, thereby preventing the spout assembly from being accidentally opened and causing leakage. Because the locking structure is located on the central surface of the receiving groove, it is closer to the position of the resultant force of the user operating the spout assembly, thereby increasing the effective force exerted by the user on the locking structure and making the locking and unlocking operations of the spout assembly easier. In addition, when the spout assembly is stored in the receiving groove, it shields the locking structure, preventing the locking structure from being exposed and improving the appearance and integrity of the cup lid.

[0009] Optionally, the end of the mouthpiece assembly closest to the drinking opening is the inlet end, and the end of the mouthpiece assembly furthest from the drinking opening is the outlet end. When the mouthpiece assembly is in the locked state, the wall surface of the receiving groove facing the outlet end is the first wall surface, and the locking structure is disposed on the first wall surface. The locking structure locks into the mouthpiece assembly at the outlet end. The locking structure is located away from the pivot axis of the mouthpiece assembly, allowing it to generate a large torque on the mouthpiece assembly with a small force, thereby stably and reliably locking the mouthpiece assembly within the receiving groove and preventing accidental loosening of the locking structure during use.

[0010] Optionally, the spout assembly includes a spout body pivotally connected to the lid, the spout body engaging with the drinking spout at the inlet end; the locking structure includes a resilient locking pin, a portion of which extends out of the first wall surface and can engage or disengage with the inner hole of the spout body at the outlet end. By utilizing the inner hole of the spout body itself to engage with the locking structure, there is no need for a dedicated mating structure for the locking structure, thereby simplifying the overall structure of the lid and reducing its production cost.

[0011] Optionally, the first wall surface is provided with a mounting hole, and a sleeve is fitted inside the mounting hole, with the opening of the sleeve facing the bottom of the mounting hole, and a pin hole provided at the bottom of the sleeve; the elastic locking pin is installed inside the sleeve, and a portion of the elastic locking pin passes through the pin hole and protrudes from the first wall surface. On the one hand, the mounting hole and the sleeve form an installation space and a telescopic space for the elastic locking pin, allowing the elastic locking pin to be stably and reliably installed in the cover body, preventing the elastic locking pin from accidentally falling off during use; on the other hand, the sleeve guides the elastic locking pin, ensuring that the elastic locking pin can only extend and retract axially, thereby ensuring the sensitivity of the elastic locking pin's action.

[0012] Optionally, the resilient locking pin includes a pin body and an elastic element. A portion of the pin body extends through the pin hole and out of the first wall surface, and both ends of the elastic element elastically abut against the bottom of the pin body and the mounting hole, respectively. Locking the nozzle body using a rigid pin body increases the stability and reliability of the nozzle body's locked state. The elastic element forces the pin body to protrude from the first wall surface, allowing the resilient locking pin to automatically move in the direction of locking the nozzle body and stably maintain the locked state.

[0013] Optionally, the spout assembly further includes a slider slidably connected to the spout body to either cover the spout body at the outlet end or expose the spout body. The slider only covers a portion of the spout body, without completely covering or concealing the entire spout body, thereby reducing the overall volume of the lid and improving the user experience. Furthermore, since the slider is connected to the spout body, rather than the lid, the user can hold the slider to rotate the spout body, improving ease of operation and effectively preventing user fingers from contaminating the spout body, thus enhancing the hygiene of the water cup.

[0014] Optionally, the spout assembly includes a spout body and a slider. The spout body is pivotally connected to the cover. The spout body engages with the drinking spout at the inlet end. The slider is slidably connected to the spout body to either cover the spout body at the outlet end or expose the spout body. The locking structure includes a protrusion protruding from the first wall surface, with a gap between the protrusion and the bottom of the receiving groove. When the spout assembly is housed in the receiving groove, the slider slides along the spout body and engages or disengages from the gap. On one hand, the slider slides along the spout body, achieving both covering the spout body and locking it to the cover, and simultaneously exposing the spout body and releasing the lock, thus simplifying the use of the cup lid and improving the user experience. On the other hand, neither the slider nor the protrusion deforms under external force. Simply locking the slider in the state of covering the spout body ensures reliable locking between the spout assembly and the cover, thus preventing accidental unlocking of the spout assembly during use.

[0015] Optionally, the locking structure is disposed at the bottom of the receiving groove, and the locking structure cooperates with the lower surface of the mouthpiece assembly. The locking structure is positioned away from the outlet end of the mouthpiece, so that the mouthpiece assembly can maintain a continuous and smooth surface near the outlet end, allowing the user to drink liquids more comfortably through the mouthpiece assembly.

[0016] Optionally, the locking structure includes two locking arms, each protruding from the bottom of the receiving groove, and the two locking arms are positioned opposite each other on either side of the center surface of the receiving groove. The nozzle assembly includes a nozzle body, which is pivotally connected to the cover. A locking post protrudes from the lower surface of the nozzle body, and the locking post can engage or disengage between the two locking arms. On one hand, the locking arms protruding from the bottom of the receiving groove form a cantilever structure, allowing the two locking arms to bend and deform, moving closer or further apart. This makes it easier for the locking post to engage or disengage between the two locking arms, making the locking and unlocking operations of the nozzle assembly less strenuous. On the other hand, the locking post, located on the pivotally connected nozzle body, prevents the locking post from deviating from the position of the locking arms, ensuring that the locking post accurately engages between the two locking grooves.

[0017] Optionally, the spout assembly further includes a slider slidably connected to the spout body to either cover the spout body at the end furthest from the drinking opening or expose the spout body. The slider only covers a portion of the spout body, without completely covering or concealing the entire spout body, thereby reducing the overall volume of the lid and improving the user experience. Furthermore, since the slider is connected to the spout body, rather than the lid, the user can hold the slider to rotate the spout body, improving ease of operation and effectively preventing finger contamination of the spout body, thus enhancing the hygiene of the water cup.

[0018] Optionally, the top of the lid is provided with a direct drinking spout, and the lid also includes a flip-top that is pivotally connected to the lid to open or close the direct drinking spout. The top of the lid is provided with both a sippy spout and a direct drinking spout, thus enabling both direct drinking and sippy drinking to be achieved simultaneously, meeting the drinking needs of different groups of people.

[0019] A second aspect of this application provides a water cup, which includes a cup body and any of the cup lids provided in this application, wherein the cup lid is detachably connected to the cup body.

[0020] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0055] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0057] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0058] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0059] like Figures 1-8As shown, this application embodiment provides a cup lid that can be connected to the mouth of a cup body and together with the cup body constitutes a water cup. The cup lid includes a lid body 1 and a spout assembly 2. The lid body 1 is used to connect to the cup body, realizing the connection and fixation between the cup lid and the cup body. The top of the lid body 1 is provided with a receiving groove 11, and the bottom 112 of the receiving groove 11 is provided with a drinking port 12. A straw can be connected below the drinking port 12 and extends into the cup body through the straw. The spout assembly 2 is disposed in the receiving groove 11 and is pivotally connected to the lid body 1. The spout assembly 2 has an open state that communicates with the drinking port 12, or a locked state that is stored in the receiving groove 11 and blocks the drinking port 12.

[0060] Specifically, the spout assembly 2 is capable of rotating relative to the lid 1. When the spout assembly 2 rotates away from the receiving groove 11, it is in an open state, connecting to the drinking spout 12, allowing the user to drink the liquid from the cup. When the spout assembly 2 rotates towards the receiving groove 11, it is in a locked state, retracting into the receiving groove 11 and blocking the drinking spout 12, preventing liquid from leaking from the drinking spout 12.

[0061] Furthermore, the receiving groove 11 is provided with a locking structure along its central surface (i.e., the plane that divides the receiving groove 11 into two symmetrical parts), so as to lock the nozzle assembly 2 within the receiving groove 11 when it is in the locked state, thereby preventing the nozzle assembly 2 from being accidentally opened and causing leakage. Since the locking structure is located on the central surface of the receiving groove 11, it is closer to the point where the user's force exerts on the nozzle assembly 2 is applied, thus increasing the effective force exerted by the user on the locking structure and making the locking and unlocking operations of the nozzle assembly 2 easier. In addition, when the nozzle assembly 2 is in the locked state, it shields the locking structure, preventing the locking structure from being exposed and improving the appearance and overall integrity of the cup lid.

[0062] Specifically, the shape of the receiving groove 11 matches the shape of the suction nozzle assembly 2, and the center surface of the receiving groove 11 is approximately the same as the center surface of the suction nozzle assembly 2. Normally, the user flips the suction nozzle assembly 2 by pinching its sides, or by pressing or lifting the center of the suction nozzle assembly 2. Therefore, the resultant force of the user operating the suction nozzle assembly 2 is always located at the center surface of the suction nozzle assembly 2, which is also the center surface of the receiving groove 11. This allows the resultant force to act directly on the locking structure, increasing the effective force exerted by the user on the locking structure.

[0063] Furthermore, the top of the lid 1 is provided with a direct drinking spout 13. That is to say, the top of the lid 1 is provided with both a sippy spout 12 and a direct drinking spout 13, thus enabling both direct drinking and sippy drinking to be achieved simultaneously, meeting the drinking needs of different groups of people. The lid also includes a flip lid 6, which is pivotally connected to the lid 1 to open or close the direct drinking spout 13. In other words, the direct drinking spout is opened and closed by flipping it. Since the flip lid 6 and the lid 1 only exert mutual pressure and do not generate mutual friction, the resistance to opening and closing the direct drinking spout 13 is reduced, making the operation of opening and closing the direct drinking spout 13 convenient and effortless.

[0064] Furthermore, the direct drinking spout 13 and the sippy spout 12 are positioned opposite each other on the two edges of the lid 1, allowing both direct drinking and sippy drinking to be achieved at the edges of the lid 1, thus providing a more comfortable drinking angle and improving the user experience of the cup. The flip-top 6 and the sippy spout assembly 2 are arranged in a straight line on the surface of the lid 1 to improve the appearance of the lid. The flip-top 6 has two connecting arms 61 at the end near the sippy spout 12, which are pivotally connected to the lid 1. At least a portion of the sippy spout assembly 2 can be stored between the two connecting arms 61, which not only meets the length requirements of the flip-top 6 and the sippy spout assembly 2 within the small space of the lid 1, but also makes the overall structure of the lid more compact.

[0065] The nozzle assembly 2 has an inlet end 2a and an outlet end 2b at opposite ends. The nozzle assembly 2 has an internal liquid channel connecting the inlet end 2a and the outlet end 2b. The end of the nozzle assembly 2 closest to the drinking opening 12 is the inlet end 2a, where it engages with the drinking opening 12. The pivot of the nozzle assembly 2 is located near the inlet end 2a. The end of the nozzle assembly 2 furthest from the drinking opening 12 is the outlet end 2b, through which the user drinks the liquid.

[0066] Furthermore, the spout assembly 2 includes a spout body 21 and a slider 22. The spout body 21 is pivotally connected to the cover 1, either away from the receiving groove 11 and communicating with the drinking spout 12, or housed in the receiving groove 11 and blocking the drinking spout 12. That is, the inner hole 211 of the spout body 21 forms a liquid channel. At the inlet end 2a, the spout body 21 cooperates with the drinking spout 12, and at the outlet end 2b, the user drinks liquid through the spout body 21. The slider 22 is slidably connected to the spout body 21 to either cover the spout body 21 at the end away from the drinking spout 12 (i.e., the outlet end 2b) or expose the spout body 21. In other words, the slider assembly forms a dust cover for the spout body 21. Since the slider 22 only covers a part of the spout body 21, without completely covering or housing the entire spout body 21, the overall volume of the cup lid can be reduced, improving the user experience of the cup. In addition, the slider 22 is connected to the mouthpiece body 21, rather than to the cover 1. The user can hold the slider 22 to achieve the flipping movement of the mouthpiece body 21, which can not only improve the convenience of operation, but also effectively prevent the user's fingers from contaminating the mouthpiece body 21, thus improving the cleanliness and hygiene of the water cup.

[0067] Specifically, when the slider 22 blocks the mouthpiece body 21 at the outlet end 2b, the slider 22 is in the closed state, serving as a dustproof element to prevent the mouthpiece body 21 from being contaminated by dust at the outlet end 2b, thus affecting the cleanliness and hygiene of the mouthpiece body 21. When the mouthpiece body 21 is exposed at the outlet end 2b, the slider 22 is in the open state, allowing the user to drink the liquid from the cup through the mouthpiece body 21 at the outlet end 2b. The slider 22 and the mouthpiece body 21 can be connected by an interference fit or a snap-fit ​​mechanism, allowing the slider 22 to stably remain in any suitable position, such as the open position or the retracted position. When the mouthpiece assembly 2 is retracted into the receiving groove 11, the wall surface of the receiving groove 11 facing the outlet end 2b is the first wall surface 111.

[0068] The slider 22 may have a protruding handle 221 on its surface. The user applies external force to the slider 22 through the handle 221, causing the slider 22 to slide along the nozzle body 21. On the one hand, this reduces the space required to operate the slider 22 and improves the ease of operation; on the other hand, the direction of the external force applied by the user to the slider 22 is parallel to the direction of movement of the slider 22, making the operation of the slider 22 more effortless.

[0069] like Figures 2-5 As shown, in some embodiments, a locking structure is disposed on the first wall surface 111, and the locking structure cooperates with the nozzle assembly 2 at the outlet end 2b. The locking structure is located away from the pivot axis of the nozzle assembly 2, so that the locking structure generates a large torque on the nozzle assembly 2 with a small force, thereby enabling the nozzle assembly 2 to be stably and reliably locked in the receiving groove 11, preventing the locking structure from accidentally loosening during use.

[0070] like Figure 2 and Figure 3 As shown, in one embodiment, the locking structure includes a resilient locking pin 3, which is capable of extending and retracting along a direction perpendicular to the first wall surface 111. A portion of the resilient locking pin 3 extends out of the first wall surface 111 and can engage or disengage with the inner hole 211 of the nozzle body 21 at the outlet end 2b. By utilizing the inner hole 211 of the nozzle body 21 itself to cooperate with the locking structure, there is no need to set up a special mating structure for the locking structure, thereby simplifying the overall structure of the cup lid and reducing the production cost of the cup lid.

[0071] Furthermore, the first wall surface 111 is provided with a mounting hole 14, and a sleeve 15 is fitted inside the mounting hole 14. The opening of the sleeve 15 faces the bottom of the mounting hole 14, and the bottom of the sleeve 15 is provided with a pin hole. The elastic locking pin 3 is installed inside the sleeve 15, and a part of the elastic locking pin 3 extends out of the first wall surface 111 through the pin hole. On the one hand, the mounting hole 14 and the sleeve 15 form the mounting space and telescopic space of the elastic locking pin 3, so that the elastic locking pin 3 is stably and reliably installed inside the cover body 1, preventing the elastic locking pin 3 from accidentally falling off during use; on the other hand, the sleeve 15 plays a guiding role for the elastic locking pin 3, ensuring that the elastic locking pin 3 can only extend and retract along the axial direction, thereby ensuring the sensitivity of the elastic locking pin 3.

[0072] Furthermore, the elastic locking pin 3 includes a pin body 31 and an elastic element 32 (e.g., a spring), with the elastic element 32 and pin body 31 installed inside the sleeve 15. A portion of the pin body 31 extends through the pin hole and out of the first wall surface 111, thereby locking the nozzle body 21 through the rigid pin body 31, which can increase the stability and reliability of the locking state of the nozzle body 21. The two ends of the elastic element 32 elastically abut against the bottom of the pin body 31 and the mounting hole 14, respectively, to force the pin body 31 to protrude from the first wall surface 111, so that the elastic locking pin 3 can automatically move in the direction of locking the nozzle body 21 and stably remain in the state of locking the nozzle body 21.

[0073] like Figure 4 and Figure 5As shown, in another embodiment, the locking structure includes a protrusion 4 protruding from the first wall surface 111, and a gap 41 is provided between the protrusion 4 and the bottom 112 of the receiving groove 11. When the spout assembly 2 is housed in the receiving groove 11, the slider 22 slides along the spout body 21 and engages or disengages from the gap 41. On the one hand, the slider 22 slides along the spout body 21, achieving mutual locking with the lid 1 while covering the spout body 21, and releasing the mutual locking with the lid 1 while exposing the spout body 21, thereby making the use of the cup lid more convenient and improving the user experience of the cup; on the other hand, neither the slider 22 nor the protrusion 4 will deform under external force. As long as the slider 22 is locked in the state of covering the spout body 21, reliable locking between the spout assembly 2 and the lid 1 can be guaranteed, thus preventing the spout assembly 2 from accidentally disengaging during use.

[0074] like Figures 6-8 As shown, in some embodiments, a locking structure is disposed at the bottom 112 of the receiving groove 11, and the locking structure cooperates with the lower surface of the mouthpiece assembly 2. The locking structure is disposed away from the outlet end 2b of the mouthpiece, so that the mouthpiece assembly 2 can maintain a continuous and smooth surface near the outlet end 2b, so that the user can drink liquid more comfortably through the mouthpiece assembly 2.

[0075] Specifically, the locking structure and the lower surface of the nozzle assembly 2 can be connected in a snap-fit ​​manner. The locking structure cooperates with the lower surface of the nozzle body 21, or the locking structure cooperates with the lower surface of the sliding member 22.

[0076] In one embodiment, the locking structure includes two latching arms 5, which protrude from the bottom 112 of the receiving groove 11. The two latching arms 5 are positioned opposite each other on both sides of the center surface of the receiving groove 11, forming a latching groove 51 with a smaller opening and a larger internal space between the two latching arms 5. A latching post 212 protrudes from the lower surface of the suction nozzle body 21. The latching post 212 forms a constricted structure with a larger end and a smaller internal space. The latching post 212 can engage or disengage between the latching arms 5, realizing the mutual cooperation between the locking structure and the suction nozzle assembly 2. On the one hand, the locking arm 5 protrudes from the bottom 112 of the receiving groove 11 to form a cantilever structure, which allows the two locking arms 5 to bend and deform to move closer or further apart from each other, so that the locking post 212 can be more easily locked into or released from between the two locking arms 5, making the locking and unlocking operations of the nozzle assembly 2 easier; on the other hand, the locking post 212 is set on the pivotally connected nozzle body 21, which can prevent the locking post 212 from deviating from the position of the locking arm 5, thereby ensuring that the locking post 212 can be accurately locked into between the two locking grooves 51.

[0077] In addition, this application also provides a water cup, which includes a cup body and any of the cup lids provided in this application. The cup lid is detachably connected to the mouth of the cup body, for example, the cup lid is connected to the opening of the cup body by a snap or thread or other appropriate means; a sealing fit can be formed between the cup lid and the cup body, for example, a sealing ring can be provided between the cup lid and the cup body.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
