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. A spout may be provided on the lid, allowing the user to drink the liquid inside the cup. Typically, the lid comprises an interconnected body and a top cover, with the spout housed between the body and the top cover for dust protection. This structure results in a relatively large overall size of the lid, affecting the user experience. Utility Model Content

[0003] This application provides a cup lid and a water cup to reduce the overall volume of the cup lid 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 drinking spout;

[0006] The mouthpiece includes a drinking portion and a connecting portion disposed opposite to each other, the connecting portion being pivotally connected to the cover body so that the mouthpiece can connect to or block the drinking opening;

[0007] A slider is slidably connected to the mouthpiece to either cover the drinking part or expose the drinking part.

[0008] The cup lid provided in this application embodiment includes a lid body, a spout, and a slider. The lid body has a drinking opening, and the spout includes a drinking portion and a connecting portion disposed opposite each other. The connecting portion is pivotally connected to the lid body so that the spout can connect to or block the drinking opening. The slider is slidably connected to the spout to cover the drinking portion or expose the drinking portion. When the slider covers the drinking portion, the slider is in a closed state, and the slider plays a dustproof role, preventing the drinking portion from being contaminated by dust and affecting the cleanliness and hygiene of the spout. When the drinking portion is exposed, the slider is in an open state, and the user can drink the liquid in the cup through the spout. On the one hand, the sliding component covers the drinking part of the spout, thus preventing dust accumulation. Since the sliding component only covers a portion of the spout, rather than completely obscuring or concealing the entire spout, the overall size of the lid can be reduced, improving the user experience. On the other hand, the sliding component is connected to the spout, not the lid, preventing the spout's position from affecting its own. This means the sliding component can freely switch between open and closed states regardless of the spout's orientation, achieving dust prevention without altering the spout's position, further enhancing the user experience. Furthermore, users can hold the sliding component to rotate the spout, improving ease of operation and effectively preventing finger contamination, thus improving hygiene.

[0009] Optionally, along the sliding direction of the slider, the nozzle is provided with at least one locking groove, and the slider is provided with a locking component; when the locking component is partially embedded in the locking groove, the position of the slider relative to the nozzle is fixed; thereby fixing the slider in the target position and preventing the position of the slider from changing automatically during use, making it difficult to achieve the expected use purpose; when the locking component slides out of the locking groove, the slider can slide relative to the nozzle, thereby facilitating the user to adjust the position of the slider as needed.

[0010] Optionally, the nozzle is provided with at least two locking grooves, wherein the locking groove closest to the drinking part is the first locking groove, and the locking groove closest to the connecting part is the second locking groove; when the locking component is partially embedded in the first locking groove, the sliding member blocks the drinking part, thereby fixing the sliding member in the closed position and providing a reliable dustproof function; when the locking component is partially embedded in the second locking groove, the drinking part is exposed outside the sliding member, thereby fixing the sliding member in the open position and ensuring that the user can drink the liquid in the cup through the drinking part. Optionally, the locking assembly includes: a pin, a portion of which is exposed on the side of the slider facing the nozzle. The pin can slide in a direction close to or away from the nozzle, and the direction of movement of the pin is perpendicular to the direction of force applied to the pin. This ensures that the slider remains stably in the target position and reduces the movement resistance of the slider, making its operation easier. An elastic element is also included, which elastically abuts against the end of the pin away from the nozzle, forcing the pin to abut against the surface of the nozzle. When the locking assembly moves with the slider, and the pin is aligned with the locking groove, the pin automatically engages in the locking groove under the action of the elastic element, thus ensuring that the slider accurately remains in the target position.

[0011] Optionally, the locking assembly further includes a sleeve connected to the sliding member, the sleeve extending in a direction away from the nozzle, and the end of the sleeve away from the nozzle being a closed end; the pin is slidably connected to the sleeve, with a portion of the pin exposed at the end of the sleeve facing the nozzle; the elastic member is housed within the sleeve, with its two ends elastically abutting against the pin and the closed end of the sleeve, respectively. On one hand, the sleeve guides the pin, increasing the accuracy of its movement and reducing potential pin wobble; on the other hand, the sleeve provides local reinforcement within the sliding member, preventing direct interaction between the pin or the elastic member and the sliding member, thus preventing deformation, cracking, or scratches on the sliding member.

[0012] Optionally, the locking assembly includes: a fixing part, which is integrally formed with the sliding member to reduce the number of parts and improve the convenience of container cap assembly; and a protrusion, which protrudes from the fixing part on the side facing the nozzle. The protrusion engages or disengages from the locking groove as the sliding member moves. Since the deformation of the protrusion is very small, it can increase the stability of the cooperation between the sliding member and the nozzle.

[0013] Optionally, the sliding member has a through groove, and the fixing part is strip-shaped. Both ends of the fixing part along its length are connected to the groove wall of the through groove, and a gap is provided between both ends of the fixing part along its width and the groove wall of the through groove. The fixing part can be bent and deformed along its length, thereby increasing the overall deformation of the locking assembly, reducing the movement resistance of the sliding member, and making the operation of the sliding member more effortless.

[0014] Optionally, the suction nozzle is provided with a sliding groove, and the sliding groove and the locking groove are arranged along the sliding direction of the slider, with the sliding groove and the locking groove spaced apart from each other. On the one hand, when it is necessary to change the position of the slider, the protrusion disengages from the locking groove and falls into the sliding groove, and slides along the sliding groove, thereby reducing the movement resistance of the slider and making the operation of the slider easier; on the other hand, when it is necessary to fix the position of the slider, the protrusion disengages from the end of the sliding groove and engages in the locking groove, thereby serving as a prompt and ensuring that the slider can stay at the target position.

[0015] Optionally, the sliding member is sleeved on the outer periphery of the suction nozzle. On the one hand, the outer periphery of the suction nozzle provides reliable radial limiting and axial guidance for the sliding member, eliminating the need for a dedicated guide structure between the suction nozzle and the sliding member, thus simplifying the overall structure and reducing production costs. On the other hand, it increases the structural strength of the sliding member itself, as well as the connection strength between the sliding member and the suction nozzle, preventing damage such as deformation, breakage, or falling off of the sliding member.

[0016] Optionally, the lid has a direct drinking spout, and the lid also includes a flip-top, which is pivotally connected to the lid to open or close the direct drinking spout. The lid allows for both direct drinking and sipping, meeting the drinking needs of different groups.

[0017] 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 connected to the mouth of the cup body.

[0018] 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

[0056] 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

[0057] 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.

[0058] 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.

[0059] 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.

[0060] like Figure 1 As shown in the figure, this application embodiment provides a water cup, which includes a cup body 02 and a cup lid 01. The cup lid 01 is detachably connected to the mouth of the cup body 02. For example, the cup lid 01 is connected to the opening of the cup body 02 by a suitable means such as a snap or thread. A sealing fit can be formed between the cup lid 01 and the cup body 02. For example, a sealing ring can be provided between the cup lid 01 and the cup body 02.

[0061] like Figures 2-7 As shown, the cup lid 01 provided in this embodiment includes a lid body 1 and a spout 2. The lid body 1 is used to connect to the cup body 02, realizing the connection and fixation between the cup lid 01 and the cup body 02. The lid body 1 is provided with a drinking port 11, and a straw can be connected to the bottom of the drinking port 11. The spout 2 includes a drinking part 21 and a connecting part 22 disposed opposite to each other. The connecting part 22 is pivotally connected to the lid body 1 so that the spout 2 can connect to or block the drinking port 11. Specifically, the spout 2 can rotate relative to the lid body 1; when the spout 2 rotates away from the lid body 1, the spout 2 can open and connect to the drinking port 11 so that the user can drink the liquid in the cup through the spout 2 (see reference). Figure 4 When the spout 2 is flipped towards the lid 1, the spout 2 can be retracted and block the drinking spout 11, thus both retracting the spout 2 and closing the drinking spout 11 to prevent liquid from leaking from the drinking spout 11 (see reference). Figures 5-7 The nozzle 2 and the cover 1 can be connected by an interference fit or a snap-fit, so that the nozzle 2 can be stably held in any appropriate position, such as the open position or the storage position.

[0062] Specifically, the mouthpiece 2 has a liquid channel 23 inside, which passes through the connecting part 22 and forms a liquid inlet 231. The liquid channel 23 also passes through the drinking part 21 and forms a liquid outlet 232. When the mouthpiece 2 is connected to the drinking opening 11, the liquid inlet 231 overlaps with the drinking opening 11 to at least a portion, allowing the liquid in the cup to pass through the drinking opening 11 and enter the mouthpiece 2. When the mouthpiece 2 blocks the drinking opening 11, the liquid inlet 231 is completely misaligned with the drinking opening 11, preventing the liquid in the cup from passing through the drinking opening 11 and entering the mouthpiece 2.

[0063] A first vent hole 13 can be provided on one side of the drinking spout 11, and a first plug 26 can be provided directly below the spout 2 opposite to the first vent hole 13. When the spout 2 is closed, the first plug 26 closes the first vent hole 13 to prevent liquid from leaking along the first vent hole 13; when the spout 2 is open, the first plug 26 opens the first vent hole 13 to balance the pressure inside and outside the cup.

[0064] Furthermore, the lid 1 is provided with a direct drinking spout 12, meaning that the lid 1 simultaneously has a sippy spout 11 and a direct drinking spout 12, thus enabling both direct drinking and sippy drinking via the spout 2 to meet the drinking needs of different groups. The cup lid 01 also includes a flip lid 4, which is pivotally connected to the lid 1 to open or close the direct drinking spout 12. That is, the direct drinking spout is opened and closed by flipping it. Since the flip lid 4 and the lid 1 only exert mutual pressure and do not generate mutual friction, the resistance to opening and closing the direct drinking spout 12 is reduced, making the operation of opening and closing the direct drinking spout 12 convenient and effortless.

[0065] Specifically, the drinking spout 12 and the sipping spout 11 are positioned opposite each other on both sides of the axis of the lid 1. The flip-top 4 and the sipping nozzle 2 are arranged sequentially along the diameter of the lid 1, that is, the flip-top 4 and the sipping nozzle 2 extend and are arranged in a straight line to improve the appearance of the container lid. The flip-top 4 has a groove at the end near the sipping nozzle 2, and a part of the sipping nozzle 2 extends into the groove to improve the compactness of the overall structure of the lid 01.

[0066] A second vent 14 can be provided on one side of the drinking spout 12, and a second plug can be provided directly below the flip cover 4 opposite the second vent 14. When the flip cover 4 is closed, the second plug closes the second vent 14 to prevent liquid from leaking along the second vent 14; when the flip cover 4 is opened, the second plug opens the second vent 14 to balance the pressure inside and outside the cup.

[0067] Furthermore, the cup lid 01 provided in this embodiment also includes a slider 3. The slider 3 is slidably connected to the spout 2 to either cover the drinking portion 21 or expose the drinking portion 21; when the slider 3 covers the drinking portion 21 (refer to...) Figure 6 and Figure 7 When the sliding part 3 is in the closed state, it serves as a dustproof element, preventing the drinking part 21 from being contaminated by dust and affecting the cleanliness and hygiene of the mouthpiece 2. When the drinking part 21 is exposed (see reference...), Figure 4 and Figure 5With the slider 3 in the open position, the user can drink the liquid from the cup through the spout 2. On one hand, the slider 3 covers the drinking portion 21 of the spout 2, thus preventing dust accumulation. Since the slider 3 only covers a portion of the spout 2, without completely covering or concealing the entire spout 2, the overall volume of the cup lid 01 can be reduced, improving the user experience. On the other hand, the slider 3 is connected to the spout 2, not the lid 1, preventing the state of the spout 2 from affecting the state of the slider 3. In other words, the slider 3 can freely switch between open and closed states regardless of the spout 2's position, achieving dust prevention for the spout 2 without changing its state, further enhancing the user experience. Furthermore, the user can hold the slider 3 to rotate the spout 2, improving ease of operation and effectively preventing the user's fingers from contaminating the spout 2, thus improving the cleanliness and hygiene of the cup.

[0068] Furthermore, the surface of the slider 3 may be provided with a handle 33, through which the user applies external force to the slider 3, causing the slider 3 to slide along the nozzle 2. On the one hand, this reduces the space required to operate the slider 3 and improves the convenience of operating the slider 3; on the other hand, the direction of the external force applied by the user to the slider 3 is parallel to the direction of movement of the slider 3, making the operation of the slider 3 more effortless.

[0069] Furthermore, the slider 3 is fitted around the outer periphery of the suction nozzle 2, meaning that at least one section of the slider 3 is configured as a circumferentially closed annular structure. On one hand, the outer periphery of the suction nozzle 2 provides reliable radial limiting and axial guidance for the slider 3, eliminating the need for a dedicated guide structure between the suction nozzle 2 and the slider 3, thus simplifying the overall structure and reducing production costs. On the other hand, it increases the structural strength of the slider 3 itself, as well as the connection strength between the slider 3 and the suction nozzle 2, preventing damage such as deformation, breakage, or falling off of the slider 3. Understandably, in other embodiments, the slider 3 may only cover the portion of the suction nozzle 2 facing away from the cover 1, for example, by configuring the slider 3 as a plate-like or C-shaped structure.

[0070] Furthermore, along the sliding direction of the slider 3, the nozzle 2 is provided with at least one locking groove 24, and the slider 3 is provided with a locking component 31. When the locking component 31 is partially embedded in the locking groove 24, the position of the slider 3 relative to the nozzle 2 is fixed, thereby fixing the slider 3 in the target position, such as fixing the slider 3 in the open or closed position, preventing the position of the slider 3 from changing automatically during use and making it difficult to achieve the expected use purpose; when the locking component 31 slides out of the locking groove 24, the slider 3 can slide relative to the nozzle 2, thereby facilitating the user to adjust the position of the slider 3 as needed.

[0071] In some embodiments, the nozzle 2 is provided with at least two locking grooves 24, each locking groove 24 being spaced apart along the sliding direction of the slider 3. The locking groove 24 closest to the drinking portion 21 is the first locking groove, and the locking groove 24 closest to the connecting portion 22 is the second locking groove. When the locking assembly 31 is partially embedded in the first locking groove, the slider 3 blocks the drinking portion 21, thereby fixing the slider 3 in the closed position and providing reliable dust protection. When the locking assembly 31 is partially embedded in the second locking groove, the drinking portion 21 is exposed outside the slider 3, thereby fixing the slider 3 in the open position and ensuring that the user can drink the liquid in the cup through the drinking portion 21.

[0072] like Figure 8 As shown, in one embodiment, the locking assembly 31 includes a pin 311. A portion of the pin 311 is exposed on the side of the slider 3 facing the nozzle 2. The pin 311 can slide in a direction close to or away from the nozzle 2, allowing it to engage or disengage from the locking groove 24. Furthermore, the direction of movement of the pin 311 is perpendicular to the direction of force applied to it. This ensures that the slider 3 remains stably in the target position while reducing the resistance to movement, making operation of the slider 3 easier. Specifically, when the pin 311 slides towards the nozzle 2, it engages in the locking groove 24, thus reliably fixing the slider 3; when the pin 311 slides away from the nozzle 2, it disengages from the locking groove 24, thereby reducing the resistance to movement of the slider 3.

[0073] Furthermore, the end of the pin 311 facing the nozzle 2 can be spherical, for example, the pin 311 can be spherical or cylindrical with a ball head. This reduces the sliding resistance of the pin 311 along the surface of the nozzle 2 and allows the pin 311 to interact with the groove wall of the locking groove 24, forcing the pin 311 to slide automatically away from the nozzle 2, thereby allowing the locking assembly 31 to automatically disengage from the locking groove 24, further improving the convenience of operation.

[0074] Furthermore, the locking assembly 31 also includes an elastic element 312. The elastic element 312 elastically abuts against the end of the pin 311 facing away from the nozzle 2, so as to force the pin 311 to abut against the surface of the nozzle 2. When the locking assembly 31 moves with the sliding member 3, so that the pin 311 is facing the locking groove 24, under the action of the elastic element 312, the pin 311 can automatically engage with the locking groove 24, thereby ensuring that the sliding member 3 accurately stops at the target position.

[0075] Furthermore, the locking assembly 31 also includes a sleeve 313, which is connected to the sliding member 3 and extends in a direction away from the nozzle 2. A pin 311 is slidably connected to the sleeve 313, with a portion of the pin 311 exposed at the end of the sleeve 313 facing the nozzle 2. On one hand, the sleeve 313 guides the pin 311, increasing the accuracy of its movement and reducing potential wobbling. On the other hand, the sleeve 313 provides local reinforcement within the sliding member 3, preventing the pin 311 from directly interacting with the sliding member 3, thus preventing deformation or breakage of the sliding member 3.

[0076] Furthermore, the end of the sleeve 313 facing away from the nozzle 2 is a closed end. The elastic element 312 is housed within the sleeve 313, with both ends of the elastic element 312 elastically abutting against the pin 311 and the closed end of the sleeve 313, respectively. On one hand, this allows the sleeve 313, the elastic element 312, and the pin 311 to be assembled outside the sliding member 3 to form the locking assembly 31, which is then inserted into the sliding member 3 as a whole, improving the convenience of the container cap assembly operation. On the other hand, it avoids direct interaction between the elastic element 312 and the sliding member 3, thereby preventing scratches or other damage to the surface of the sliding member 3 caused by the elastic element 312.

[0077] like Figure 9 and Figure 10 As shown, in another embodiment, the locking assembly 31 includes a fixing part 314 and a protrusion 315. The fixing part 314 is integrally formed with the sliding member 3 to reduce the number of parts and improve the convenience of container cap assembly operation; the protrusion 315 protrudes from the fixing part 314 on the side facing the nozzle 2, and the protrusion 315 engages or disengages from the locking groove 24 as the locking assembly 31 moves. Since the deformation of the protrusion 315 is very small, it can increase the stability of the interaction between the sliding member 3 and the nozzle 2.

[0078] Furthermore, the sliding member 3 is provided with a through groove 32, and the fixing part 314 is strip-shaped. The two ends of the fixing part 314 along its own length direction are respectively connected to the groove wall of the through groove 32. The two ends of the fixing part 314 along its own width direction are separated from the groove wall of the through groove 32, so that the fixing part 314 can be bent and deformed along its own length direction, thereby increasing the overall deformation of the locking assembly 31, reducing the movement resistance of the sliding member 3, and making the operation of the sliding member 3 more effortless.

[0079] Furthermore, the suction nozzle 2 is provided with a sliding groove 25, which is arranged along the sliding direction of the slider 3, and the sliding groove 25 and the locking groove 24 are spaced apart from each other. On the one hand, when it is necessary to change the position of the slider 3, the protrusion 315 disengages from the locking groove 24 and falls into the sliding groove 25, and slides along the sliding groove 25, thereby reducing the movement resistance of the slider 3 and making the operation of the slider 3 easier; on the other hand, when it is necessary to fix the position of the slider 3, the protrusion 315 disengages from the end of the sliding groove 25 and engages in the locking groove 24, thereby serving as a prompt and ensuring that the slider 3 can stay in the target position.

[0080] 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.
