Description

Technical Field

[0001] This invention relates to the field of double drinking cup technology, and more particularly to a cup lid and a double drinking cup. Background Technology

[0002] Dual-drink cups, which can switch between direct drinking and sipping modes, have been widely used in daily commutes, offices, outdoor travel, and family childcare scenarios.

[0003] Currently, most mainstream dual-drink cups use a multi-button independent control structure for their lids. Specifically, the independent buttons corresponding to the drinking spout and the sippy spout drive two independent locking and unlocking mechanisms, enabling the switching of different drinking modes.

[0004] However, the existing cup lids require different buttons to be identified and operated when switching drinking modes, which is easy to accidentally touch or difficult to operate, especially when using one hand; moreover, the multiple independent mechanisms not only make the cup lid structure complicated, but also make it impossible to quickly switch between the two drinking modes with a single operation, which is inconvenient to use.

[0005] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0006] The purpose of this invention is to provide a cup lid and a dual-drinking cup to avoid the risk of accidental touch and operational difficulties when operating with one hand, eliminate the need for step-by-step operation, achieve quick switching between dual-drinking modes, and significantly improve ease of use.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A cup lid includes a lid body, a straw, a drinking spout, a mouthpiece, a sealing component, and a linkage component, wherein:

[0009] The cover is provided with a receiving cavity, and a connecting hole is provided on the bottom wall of the receiving cavity;

[0010] The top end of the straw is engaged in the connecting hole;

[0011] The drinking spout is located at the edge of the cover;

[0012] The nozzle is rotatably disposed within the receiving cavity. The nozzle has a drinking state extending out of the receiving cavity and a receiving state being received into the receiving cavity. In the drinking state, the nozzle is in communication with the straw.

[0013] The sealing element can be engaged with the edge of the cap to close or open the drinking spout;

[0014] The linkage is disposed on the mouthpiece, and the end of the linkage away from the mouthpiece is hinged to the sealing member, so that the mouthpiece can be switched between drinking state and holding state by rotating the linkage by flipping the sealing member.

[0015] Preferably, the other end of the linkage is hinged to the side of the suction nozzle near the connecting hole.

[0016] Preferably, when the nozzle is in the receiving state, the linkage can be adapted to be embedded in the receiving cavity.

[0017] Preferably, the outer peripheral edge of the cover extends upward to form an annular flange, and the annular flange has a transition slope on the side facing the center of the cover.

[0018] Preferably, the drinking spout is located on the transition slope and is close to the outer peripheral sidewall of the cover.

[0019] Preferably, the sealing element includes a first bonding surface and a second bonding surface, wherein:

[0020] The first bonding surface can be bonded to the transition slope;

[0021] The second bonding surface can be bonded to the outer peripheral sidewall of the cover;

[0022] The sealing component has elastic deformation capability, so that the first bonding surface and the second bonding surface always have an elastic tendency to move closer to each other, so that the sealing component and the edge of the cover can be engaged by the first bonding surface bonding with the transition slope and the second bonding surface bonding with the outer peripheral sidewall of the cover.

[0023] Preferably, the sealing member has an arc groove recessed on the side opposite to the second contact surface, the arc groove being used for the user's finger to insert and apply force to pull the sealing member.

[0024] Preferably, a spherical groove is provided on the bottom wall of the receiving cavity, and the suction nozzle is provided with a spherical surface, which is adapted to the spherical groove and can rotate relative to it.

[0025] Preferably, the connecting hole is located at the center of the spherical groove, and the axis of the connecting hole is collinear with the axis of the spherical groove.

[0026] A double-drinking cup includes a cup body and the aforementioned cup lid, wherein the cup lid is detachably fitted onto the opening of the cup body.

[0027] The beneficial effects of this invention are:

[0028] The cup lid provided by this invention forms a linkage structure through the hinge of the sealing component and the linkage component. This integrates the opening or closing of the drinking spout and the switching between the sippy cup and the drinking spout into a single flip operation. This eliminates the need to identify multiple independent buttons, resulting in a smooth and continuous operation. It avoids the risk of accidental touches and operational difficulties associated with single-handed operation, and replaces the existing multiple independent locking and opening mechanisms with a linkage structure, simplifying the overall structure of the cup lid. Simultaneously, the single flip action can simultaneously complete the switching between dual drinking modes, eliminating the need for separate steps and enabling rapid switching between modes, significantly improving ease of use.

[0039] The invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the drawings, not the entire structure.

[0040] In the description of the invention, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the invention based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0043] Please see Figures 1 to 4 This embodiment provides a cup lid, including a lid body 1, a straw, a drinking spout 2, a mouthpiece 3, a sealing member 4, and a linkage member 5. The lid body 1 has a receiving cavity 11, and a communicating hole 12 is formed on the bottom wall of the receiving cavity 11. The tip of the straw is engaged in the communicating hole 12. The drinking spout 2 is located at the edge of the lid body 1. The mouthpiece 3 is rotatably disposed within the receiving cavity 11, and has a drinking state extending out of the receiving cavity 11 and a receiving state being contained within the receiving cavity 11. In the drinking state, the mouthpiece 3 is in communication with the straw. The sealing member 4 can engage with the edge of the lid body 1 to close or open the drinking spout 2. The linkage member 5 is disposed on the mouthpiece 3, and the end of the linkage member 5 away from the mouthpiece 3 is hinged to the sealing member 4, so that by flipping the sealing member 4, the linkage member 5 can be rotated to control the switching of the mouthpiece 3 between the drinking state and the receiving state.

[0044] In the initial state, the mouthpiece 3 is located within the receiving cavity 11 of the lid 1, and the sealing member 4 is engaged with the edge of the lid 1 to close the drinking spout 2. The mouthpiece 3 is not connected to the straw. When using the drinking spout 2, a flipping force is applied to the sealing member 4 to disengage it from the engagement with the edge of the lid 1, and the drinking spout 2 opens. At this time, one can drink directly through the open drinking spout 2. If one stops using the product, the sealing member 4 is flipped in the opposite direction to re-engage with the edge of the lid 1, the drinking spout 2 closes, the mouthpiece 3 remains in the receiving state, and the product returns to the initial state.

[0045] When using the spout 3, apply a flipping force to the sealing piece 4 to disengage it from the edge of the lid 1. The drinking spout 2 opens first. Continue flipping the sealing piece 4 to drive the linkage 5 to rotate synchronously, thereby driving the spout 3 to rotate within the receiving cavity 11 to the drinking position. When the spout 3 is in the drinking position, it will be precisely connected to the straw. After completing the operation, you can drink through the extended spout 3. If you stop using it, flip the sealing piece 4 in the opposite direction to re-engage it with the edge of the lid 1, closing the drinking spout 2. The spout 3 will then rotate back to the receiving position, disconnecting from the straw and restoring the initial state.

[0046] This design, through the hinged connection between the sealing component 4 and the linkage component 5, forms a linkage structure that integrates the opening or closing of the drinking spout 2 and the switching between the sippy nozzle 3's containing and drinking states into a single flip operation. This eliminates the need to identify multiple independent buttons, resulting in a seamless operation. It avoids the risk of accidental touches and operational difficulties associated with single-handed operation, and replaces the existing multiple independent locking and opening mechanisms with a linkage structure, simplifying the overall lid structure. Simultaneously, the single flip action can synchronously complete the switching between dual drinking modes, eliminating the need for separate steps and enabling rapid switching between modes, significantly improving ease of use.

[0047] To improve the comfort of using the spout 3, the other end of the linkage 5 is hinged to the side of the spout 3 near the connecting hole 12. It can be understood that the hinge of the linkage 5 to the side of the spout 3 near the connecting hole 12 is close to the pivot point of the spout 3 within the housing cavity 11 of the cover 1. This allows for a more reasonable distribution of the lever arm when the spout 3 rotates under the drive of the linkage 5, enabling a larger angle of rotation. This ensures that the spout 3 can fully extend out of the housing cavity 11 to meet drinking needs, and effectively prevents the linkage 5 from contacting or interfering with the mouth when the user uses the spout 3, thus improving drinking comfort.

[0048] Specifically, when the nozzle 3 is in the receiving state, the linkage 5 can be adapted and embedded in the receiving cavity 11. As can be seen from the above, the receiving cavity 11 simultaneously undertakes the storage function of the nozzle 3 and the linkage 5, thereby making the assembly structure of the lid 1, nozzle 3, and linkage 5 highly concentrated, effectively reducing the redundant space occupied inside the cup lid, avoiding the increase in cup lid volume due to the linkage 5 being exposed or needing to be stored separately, making the overall structure of the cup lid more compact, and further adapting to the usage needs of portable scenarios such as daily commuting, office work, and outdoor travel.

[0049] In addition, it can prevent the linkage 5 from snagging or scratching with clothing or other items in the backpack during daily carrying or operation, thus avoiding damage or deformation of the linkage 5 itself and reducing the risk of damage to the user's clothing or other items.

[0050] Furthermore, the outer peripheral edge of the lid 1 extends upward to form an annular flange 13, and a transition slope 14 is provided on the side of the annular flange 13 facing the center of the lid 1. It can be understood that the annular flange 13 provides circumferential protection for the linkage 5, so that items such as clothing and keys inside the backpack will first contact the annular flange 13, preventing them from directly touching the linkage 5. This spatially blocks the contact path between the linkage 5 and external items, effectively preventing the linkage 5 from being hooked, deformed, or scratched and damaged. In addition, when operating the lid, hand movements are guided to the outside by the annular flange 13, preventing accidental contact with the linkage 5.

[0051] Furthermore, the drinking spout 2 is located on the transition slope 14, and is close to the outer peripheral wall of the lid 1. This arrangement, with the annular flange 13 facing the center of the lid 1, forms the transition slope 14, conforming to the contour curve of the human mouth when it holds the drinking spout 2. When the user drinks from the drinking spout 2, the lips naturally rest on the transition slope 14. Compared to a sharp right-angled edge, the slope increases the contact area between the mouth and the lid 1, dispersing local contact pressure and preventing lip soreness or indentations caused by prolonged drinking, significantly improving drinking comfort. Simultaneously, the tightly fitting transition slope 14 fills the gap between the mouth and the lid 1, creating a more reliable seal and reducing leakage from the corners of the mouth during drinking, especially when the cup is tilted for better leak prevention.

[0052] Furthermore, the transition slope 14 conforms to the natural contour of the human mouth when it touches the cup. The drinking spout 2 is located on the transition slope 14, allowing the user's lips to automatically align with the drinking spout 2 when they touch the transition slope 14, without the need to deliberately adjust the angle of the head or the cup. At the same time, the drinking spout 2 is close to the outer peripheral wall of the lid 1, so when holding the lid, the hand can naturally wrap around the middle and inner area of ​​the lid 1 without obstructing the drinking path, further reducing the difficulty of one-handed drinking and improving the smoothness of drinking.

[0053] Furthermore, the sealing element 4 includes a first contact surface 41 and a second contact surface 42. The first contact surface 41 can be contacted with the transition slope 14. The second contact surface 42 can be contacted with the outer peripheral sidewall of the cover 1. The sealing element 4 has elastic deformation capability, so that the first contact surface 41 and the second contact surface 42 always have an elastic tendency to move closer to each other, so that the sealing element 4 and the edge of the cover 1 can be engaged by the first contact surface 41 contacting the transition slope 14 and the second contact surface 42 contacting the outer peripheral sidewall of the cover 1.

[0054] Understandably, the elastic deformation capability of the sealing component 4 ensures that the first contact surface 41 and the second contact surface 42 always tend to move closer to each other, thereby applying a continuous pressing force to the transition slope 14 and the outer peripheral sidewall. This tightly fills the tiny gaps between the contact surfaces caused by processing errors or wear during use, effectively preventing liquid from leaking from around the drinking spout 2 and improving the leak-proof reliability when the cup is left to stand still during daily use. It should be noted that the sealing component 4 can be made of any existing material such as food-grade silicone rubber or thermoplastic elastomer; this embodiment will not elaborate on this aspect.

[0055] To improve the ease with which users can pull the sealing component 4, an arc groove 43 is recessed on the side of the sealing component 4 opposite to the second contact surface 42. The arc groove 43 allows users to insert their fingers to apply force when pulling the sealing component 4. When the user pulls the sealing component 4, their fingers can be inserted into the arc groove 43, which significantly increases the contact area between the fingers and the sealing component 4 compared to the flat force application surface. At the same time, the sidewall of the arc groove 43 can form a circumferential limit on the fingertip, effectively preventing the fingers from slipping outwards when force is applied, and maintaining stable force application contact, especially in a humid environment where the fingers are wet or sweaty.

[0056] In this embodiment, a spherical groove 15 is formed on the bottom wall of the receiving cavity 11, and the mouthpiece 3 is provided with a spherical surface 31. The spherical surface 31 is adapted to the spherical groove 15 and can rotate relative to it. With this arrangement, the contact area between the two is larger and the force is more even, which can form an all-round positioning constraint on the mouthpiece 3, avoiding radial offset or shaking when the mouthpiece 3 rotates. It can accurately realize the angle switching from the receiving state to the drinking state, and will not cause the mouthpiece 3 to fail to align with the straw or have insufficient extension length due to rotation offset. Moreover, there is no sense of jamming during rotation, and the operation is smoother.

[0057] Furthermore, the connecting hole 12 is located at the center of the spherical groove 15, and the axis of the connecting hole 12 is collinear with the axis of the spherical groove 15. When the nozzle 3 rotates around the center of the sphere to switch states, its port that connects with the straw will always be based on the center of rotation and will not be radially offset due to changes in the rotation angle. This ensures that when the nozzle 3 switches from the holding state to the drinking state, it can accurately align with the straw in the connecting hole 12 and form a stable connection, avoiding problems such as poor drinking, leakage, or airflow obstruction caused by docking misalignment, and ensuring the reliability of the drinking mode.

[0058] This embodiment also provides a dual-drinking cup, including a cup body and the aforementioned cup lid, the cup lid being detachable and fitting onto the opening of the cup body. It is understood that the dual-drinking cup including the aforementioned cup lid enables convenient switching between dual-drinking modes, is easy to operate with one hand without accidental touches, and is suitable for various scenarios such as daily commuting, office work, and outdoor travel.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
