Description

Technical Field

[0001] The present invention relates to a cup lid facilitating single - hand operation, and also relates to a water cup with such a cup lid. Background Art

[0002] Most existing cup lids and water cups are connected by threads. This connection method requires two - hand operation to open the cup lid. One hand holds the cup body, and the other hand unscrews the lid. Therefore, this existing threaded connection method is quite inconvenient to use in some occasions. For example, when a driver is driving, it is very inconvenient and unsafe to open the cup lid to drink water.

[0003] There are also cups on the market with cup lids that can be opened with single - hand operation. The cup lid is divided into a base body and a flip - cover. The base body is threadedly connected to the cup, and the flip - cover is hinged to the base body. The flip - cover and the base body are connected by a buckle structure. During operation, the side buckle is pressed to open the flip - cover, and the water in the cup flows out through the water outlet channel on the base body for people to use. That is, during use, the cup lid is still connected to the cup, and the opened flip - cover will have a certain obstruction, affecting the user's drinking. A Chinese utility model patent "A Special Cup Lid for a Flip - Type Insulated Cup" with the patent number ZL201921290286.6 (publication number CN210383528U) discloses such a structure.

[0004] Therefore, how to provide a cup lid with a reasonable structural design and capable of realizing opening and locking operations with a single hand is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a cup lid facilitating single - hand operation with a reasonable structural design and capable of realizing opening and locking operations with a single hand in view of the above - mentioned prior - art situation.

[0006] The technical solution adopted by the present invention to solve the above - mentioned first technical problem is as follows: A cup lid facilitating single - hand operation, characterized in that it includes

[0007] a cover body, and a rubber sleeve capable of axially stretching and deforming for locking the cup body is fixed below the cover body;

[0008] a driving member, which is arranged in the cover body and can move up and down. The lower end of the driving member is connected to the rubber sleeve, so that the up - and - down movement of the driving member can drive the rubber sleeve to stretch and deform;

[0009] a locking member, which is constrained in the driving member and can slide left and right. The locking member has a lock head passing through the side wall of the driving member and a trigger part located in the driving member. The trigger part has a first inclined surface. A lock hole for inserting the lock head is opened on the inner wall of the cover body. The locking member is held by a first spring to keep the lock head in an extended trend;

[0010] The unlocking member is constrained within the driving member and can move up and down. The unlocking member is urged upward by a second spring and has a tendency to move upward to expose the unlocking member. The unlocking member has a pushing portion, and the pushing portion has a second inclined surface that cooperates with the first inclined surface.

[0011] The unlocking member and the driving member satisfy the following conditions. When the unlocking member moves downward relative to the driving member, the second inclined surface contacts and cooperates with the first inclined surface to drive the locking member to retract and the lock head to disengage from the lock hole. As the unlocking member continues to move downward, the unlocking member directly drives and moves downward relative to the cover body together with the driving member. The driving member drives the rubber sleeve to stretch downward and radially contract. Pulling the driving member to move upward relative to the cover body, the driving member drives the rubber sleeve to contract upward and radially expand. The locking member moves upward to the locking position, and the lock head on the locking member extends outward into the lock hole under the action of the first spring.

[0012] For further improvement, an exhaust hole is formed at the bottom of the driving member. A valve stem with a plug at the lower end is inserted through the exhaust hole. The valve stem is urged upward by a third spring and has a tendency to keep the plug blocking the exhaust hole. The downward movement of the unlocking member relative to the driving member can push the valve stem downward to open the exhaust hole. The setting of the exhaust hole can release the hot air in the cup body during the unlocking process, connect the inside of the cup body with the outside atmosphere, and avoid the vacuum effect making it difficult to pull the cup cover off the cup.

[0013] For a further improvement, a platform is provided at the top end of the valve stem. The platform is constrained within the driving member through a rib groove guiding structure. The lower end of the unlocking member contacts the platform. There is a spacing between the platform and the inner bottom surface of the driving member to form a moving gap. After the unlocking member drives the platform to move downward until it contacts the inner bottom surface of the driving member, the further downward movement of the unlocking member moves downward relative to the cover body together with the driving member. The platform can increase the contact area between the unlocking member and the valve stem, ensure the vertical movement of the valve stem. In addition, when the platform moves downward until it contacts the inner bottom surface of the driving member, the contact area with the driving member increases, which is beneficial to pushing the driving member downward.

[0014] Preferably, there are two locking members arranged at intervals left and right, and there are also two lock holes arranged at intervals left and right. This structure enables symmetric two-side locking between the driving member and the cover body, making the locking more stable and reliable.

[0015] To facilitate pulling the driving member, as an improvement, the top of the driving member has an annular pulling portion. Under the action of the first spring, the unlocking member passes upward through the bottom surface of the pulling portion and is exposed within the pulling portion. During operation, fingers can be inserted into the pulling portion to hook the driving member and drive it to move upward.

[0016] For further improvement, an annular covering portion is provided at the top of the cover body, and the handle portion is constrained within the annular covering portion. Since the driving member itself is relatively thin, if it is directly exposed, it is easily damaged. Constraining the handle portion within the annular covering portion plays a role in protecting the driving member, and hiding the driving member therein makes the appearance more beautiful.

[0017] Preferably, the bottom of the driving member has a disc portion, and the lower part of the rubber sleeve is sleeved on the upper part of the disc portion and fixed thereto. The large contact area between the disc portion and the rubber sleeve enables the driving member to move upward, and the force received by the rubber sleeve upward is more balanced, which can smoothly drive the rubber sleeve to expand and contract, ensuring uniform outward expansion of the rubber sleeve in the circumferential direction.

[0018] Preferably, the driving member is formed by fixing two bodies that are joined together left and right. The cover structure facilitates the assembly of various components into the driving member.

[0019] Compared with the prior art, the advantages of this cup cover are as follows: By pulling the driving member, the rubber sleeve is driven to contract upward and expand radially outward, and then the driving member and the cover body are locked together by the mobile phone, so that the rubber sleeve remains in the radially expanded state. The radially expanded rubber sleeve can cooperate with the convex ribs in the cup body to achieve locking. When unlocking, only need to press down the unlocking member, first release the locking between the driving member and the cover body, then further drive the driving member to move downward, and finally the driving member drives the rubber sleeve to stretch downward and contract radially inward. Due to the reduced diameter of the radially contracted rubber sleeve, it no longer forms an obstruction with the convex ribs in the cup body, and the cup cover can be detached from the cup.

[0020] The second technical problem to be solved by the present invention is to provide a cup cover with a reasonable structural design and capable of realizing opening and locking operations with one hand, which is convenient for one-handed operation, in view of the above-mentioned prior art status.

[0021] The technical solution adopted by the present invention to solve the above second technical problem is as follows:

[0022] A water cup, comprising a cup body having a cup mouth, characterized in that: it further includes the aforementioned cup cover, and a radially inwardly convex limiting rib is provided at the upper part within the cup body; in the state where the cup cover is inserted into the cup mouth, pulling the driving member to move upward relative to the cover body, the driving member drives the rubber sleeve to contract upward and expand radially outward and get stuck below the limiting rib to achieve locking; the driving member drives the rubber sleeve to stretch downward and contract radially inward, and the limiting rib no longer forms an obstruction to the rubber sleeve, and the rubber sleeve can be disengaged from the cup mouth upward with the cover body to achieve unlocking.

[0023] Compared with the prior art, the advantages of this water cup are as follows: By pulling the driving member, the rubber sleeve is driven to contract upward and expand radially outward. Then, the driving member and the lid body are locked together by the lock head, so that the rubber sleeve remains in a radially expanded state. The radially expanded rubber sleeve cooperates with the convex ribs in the cup body to achieve locking. When unlocking, only need to press down the unlocking member to first release the lock between the driving member and the lid body, and then further drive the driving member to move downward. Finally, the driving member drives the rubber sleeve to stretch downward and contract radially inward. Due to the reduced diameter, the radially contracted rubber sleeve no longer forms an obstruction with the convex ribs in the cup body, and the cup lid can be detached from the cup. The threaded connection between the cup lid and the cup body is cancelled, and the unique flexible characteristic of the rubber sleeve improves the sealing performance between the cup lid and the cup mouth. Unlocking can be directly achieved by pressing the unlocking member, allowing one-handed operation to open the cup lid for drinking. When locking, just insert the cup lid into the cup mouth and then lift the driving member to complete the connection between the cup lid and the cup body, which can also be achieved with one-handed operation.

[0033] The present invention will be further described in detail below in conjunction with the embodiments of the accompanying drawings.

[0034] As Figures 1 - 6 shown, it is a preferred embodiment of the cup lid.

[0035] A cup lid facilitating one-handed operation includes

[0036] A cover body 1, with a rubber sleeve 2 that can axially expand and contract and is fixed below the cover body 1 for locking a cup body.

[0037] A driving member 3, which can move up and down inside the cover body 1. The lower end of the driving member 3 is connected to the rubber sleeve 2, so that the up and down movement of the driving member 3 can drive the rubber sleeve 2 to expand and contract. The bottom of the driving member 3 has a disc portion 33, and the lower part of the rubber sleeve 2 is sleeved on the upper part of the disc portion 33 and fixed thereto. The driving member 3 is formed by fitting and fixing two opposed bodies.

[0038] A locking member 5, which is constrained inside the driving member 3 and can slide left and right. The locking member 5 has a lock head 51 that penetrates the side wall of the driving member 3 and a trigger portion 52 located inside the driving member 3. The trigger portion 52 has a first inclined surface 521. A lock hole 11 for inserting the lock head 51 is formed on the inner wall of the cover body 1. The locking member 5 is urged by a first spring 4a to keep the lock head 51 in an extended trend. There are two locking members 5, which are arranged at intervals left and right, and there are also two lock holes 11, which are arranged at intervals left and right.

[0039] An unlocking member 6, which is constrained inside the driving member 3 and can move up and down. The unlocking member 6 is urged by a second spring 4b to keep an upward movement trend to expose the unlocking member 6. The unlocking member 6 has a pushing portion 61, and the pushing portion 61 has a second inclined surface 611.

[0040] When unlocking, the unlocking member 6 moves downward relative to the driving member 3. The second inclined surface 611 contacts and cooperates with the first inclined surface 521 to drive the locking member 5 to retract and the lock head to disengage from the lock hole 11. The unlocking member 6 continues to move downward. The unlocking member 6 directly drives and moves downward relative to the cover body 1 together with the driving member 3. The driving member 3 drives the rubber sleeve 2 to stretch downward and radially contract.

[0041] When locking, the driving member 3 is pulled to move upward relative to the cover body 1. The driving member 3 drives the rubber sleeve 2 to contract upward and radially expand. The locking member 5 moves upward to the locking position. The locking member 5 makes the lock head 51 on it extend outward into the lock hole 11 under the action of the first spring 4a.

[0042] An exhaust hole 31 is formed at the bottom of the driving member 3. A valve rod 7 with a plug 71 at the lower end is inserted into the exhaust hole 31. The valve rod 7 is urged by a third spring 4c to keep an upward movement trend to block the exhaust hole 31 with the plug 71. The downward movement of the unlocking member 6 relative to the driving member 3 can push the valve rod 7 downward to open the exhaust hole 31 with the plug 71.

[0043] A platform 72 is provided at the top end of the valve stem 7. The platform 72 is constrained within the driving member 3 through a rib-groove guiding structure. The lower end of the unlocking member 6 contacts the platform 72. There is a spacing between the platform 72 and the inner bottom surface of the driving member 3 to form a moving gap D. After the unlocking member 6 drives the platform 72 to move downward until it contacts the inner bottom surface of the driving member 3, further downward movement of the unlocking member 6 causes it to move downward relative to the cover body 1 together with the driving member 3.

[0044] The top of the driving member 3 has an annular pulling portion 32. Under the action of the first spring 4a, the unlocking member 6 passes upward through the bottom surface of the pulling portion 32 and is exposed within the pulling portion 32. The top of the cover body 1 is provided with an annular covering portion 12, and the pulling portion 32 is constrained within the annular covering portion 12.

[0045] As Figures 7 - 9 shown, it is a preferred embodiment of a water cup.

[0046] A water cup includes a cup body 8 having a cup mouth 81, and also includes the cup cover described in the foregoing embodiment. A radially inwardly protruding limiting rib 82 is provided in the upper part of the cup body 8. In a state where the cup cover is inserted into the cup mouth 81, pulling the driving member 3 to move upward relative to the cover body 1 causes the driving member 3 to drive the rubber sleeve 2 to contract upward and expand radially outward and get stuck below the limiting rib 82 to achieve locking; when the driving member 3 drives the rubber sleeve 2 to stretch downward and contract radially inward, the limiting rib 82 no longer blocks the rubber sleeve 2, and the rubber sleeve 2 can be disengaged from the cup mouth 81 upward together with the cover body 1 to achieve unlocking.

[0047] The working process and principle of locking and opening the cup cover and the cup body of this water cup are as follows.

[0048] Locking process: Insert a finger into the pulling portion 32 and pull the driving member 3 upward. The upward moving driving member 3 drives the rubber sleeve 2 to contract upward and expand radially outward. The locking member 5 moves upward with the driving member 3 to the locking position. Under the action of the first spring 4a, the lock head 51 on the locking member 5 extends outward into the lock hole 11. The driving member 3 is locked together with the cover body 1, so that the rubber sleeve 2 remains expanded radially outward. The radially outwardly expanded rubber sleeve 2 cooperates with the convex rib 82 in the cup body 8 to achieve locking.

[0049] When unlocking, just press the unlocking member 6 downward. The unlocking member 6 moves downward relative to the driving member 3. The second inclined surface 611 contacts and cooperates with the first inclined surface 521 to drive the locking member 5 to contract inward and the lock head to disengage from the lock hole 11. At the same time, the downward movement of the unlocking member 6 relative to the driving member 3 can push the valve stem 7 downward to open the plug 71 to open the exhaust hole 31. When the unlocking member 6 continues to move further downward, the unlocking member 6 directly drives and moves downward relative to the cover body 1 together with the driving member 3. The driving member 3 drives the rubber sleeve 2 to stretch downward and contract radially inward; due to the reduced diameter, the radially inwardly contracted rubber sleeve 2 no longer forms an obstruction with the convex rib 82 in the cup body 8, and the cup cover can be detached from the cup.

[0050] The threaded connection between the cup lid and the cup body is cancelled, and the unique flexible property of the rubber sleeve 2 improves the sealing performance between the cup lid and the cup mouth. Unlocking can be directly achieved by pressing the unlocking component, enabling one-handed operation to open the cup lid for drinking. When locking, simply insert the cup lid into the cup mouth and then lift the driving component to complete the connection between the cup lid and the cup body, which can also be achieved with one-handed operation.

[0051] It should be noted that in the description of this embodiment, the orientation or positional relationship indicated by terms such as "front, back", "left, right", "inside, outside", "up, down", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. The terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
