Description

Technical Field

[0001] This utility model relates to a drinking device, and more particularly to a small-mouth flip-top cup lid with a hidden button. Background Technology

[0002] Water cups typically have lids to maintain a seal at the drinking spout, ensuring the entire cup is leak-proof and easy to carry. Depending on the type of drinking spout, water cup lids come in different structures and forms.

[0003] Common small-mouthed cup lids include screw-on lids and flip-top lids. Flip-top lids are a common type; users simply pry the lid open with their fingers. With technological advancements, side-locking flip-top lids have also emerged, which open by spring-loaded action after unlocking.

[0004] In the existing technology, the side-locking flip-type cup lid structure has a relatively obvious locking button. The locking structure is located partly on the cup body and partly on the lid, which limits the overall shape design of the cup. Moreover, the unlocking process is instantaneous, making it difficult to control the air pressure during the unlocking process. This can easily lead to hot water steam splashing out the moment the lid is opened, posing a safety hazard. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a small-mouth flip-top cup lid with a hidden button. The button is built into the flip-top, realizing the hidden button design, which has fewer restrictions on the overall design of the cup lid and the cup; and can eliminate the safety hazard of liquid splashing when the lid is opened.

[0006] This utility model is achieved through the following technical solution:

[0007] A small-mouth flip-top cup lid with a hidden button includes a connecting body and a flip-top assembly rotatably connected to the connecting body. The flip-top assembly seals the drinking spout on the connecting body. The flip-top assembly includes a flip-top shell rotatably mounted on one side of the connecting body. The flip-top shell has a channel, and the bottom of the channel is lined with an inner liner. A button and a rotating component are provided in the channel, which abut against each other. The button can slide vertically in the channel, and its top is exposed from the top of the channel. The rotating component is elastically supported on the inner liner by an elastic element. The rotating component has a hook that extends out of the inner liner. The drinking spout of the connecting body has hook teeth that cooperate with the hook. During the spiral lifting and lowering of the rotating component, the hook and hook teeth engage or disengage.

[0008] As a preferred embodiment of the aforementioned small-mouth flip-top cup lid, the bottom of the rotating component is provided with at least two claws evenly distributed along the circumference, and the bottom of each claw is provided with an inwardly protruding hook. The outer periphery of the drinking spout of the connecting body is provided with at least two hook teeth evenly distributed along the circumference. The movement trajectory of each claw is limited by the track body on the inner liner, so that the rotating component moves up and down in a spiral manner, thereby making each hook at the bottom of the rotating component engage with or stagger with each hook tooth on the outer periphery of the drinking spout.

[0009] As a preferred embodiment of the aforementioned small-mouth flip-top cup lid, at least two limiting grooves are formed on the outer circumferential surface of the track body. Each limiting groove is a section of groove spirally distributed along the outer circumferential surface of the track body. Each claw of the rotating component has an inwardly protruding sliding protrusion on its inner side. The sliding protrusion of each claw of the rotating component slides in a corresponding manner with each limiting groove, thereby limiting the movement trajectory of the sliding protrusion through the limiting groove, thus limiting the movement trajectory of the entire rotating component.

[0010] As a preferred embodiment of the aforementioned small-mouth flip-top cup lid, the track body is cylindrical in shape, and a sealing ring is provided at the bottom of the track body to achieve a sealed connection with the drinking spout on the connecting body.

[0011] As a preferred embodiment of the above-mentioned small-mouth flip-top cup lid, the top center of the track body is recessed to form a central recessed hole, and the bottom end of the elastic element is embedded in the central recessed hole at the top of the track body.

[0012] As a preferred embodiment of the above-mentioned small-mouth flip-top cup lid, the inner liner also includes a connecting ring. The top of the connecting ring is connected to the track body by at least two connecting ribs evenly distributed along the circumference. The inner liner is fixedly connected to the flip-top shell by the connecting ring. The number of connecting ribs is equal to the number of claws at the bottom of the rotating part, and the connecting ribs and claws are arranged alternately along the circumference.

[0013] As a preferred embodiment of the aforementioned small-mouth flip-top cup lid, a limiting protrusion is provided at the top of the channel of the flip-top shell, and a limiting step is provided on the outer circumference of the button. The limiting protrusion blocks the limiting step, thereby limiting the extreme position of the button sliding upward in the channel of the flip-top shell.

[0014] As a preferred embodiment of the above-mentioned small-mouth flip-top cup lid, at least one vertically extending guide ridge is provided on the outer circumferential surface of the button at the position above the limiting step, and a guide groove that cooperates with the guide ridge is provided on the inner side wall of the flip-top shell.

[0015] This invention has the following advantages over the prior art:

[0016] This utility model provides a small-mouth flip-top cup lid with a hidden button. The movement trajectory of each claw of the rotating component is limited by a track on the inner lining, causing the rotating component to spiral up and down. This allows the hooks at the bottom of the rotating component to engage or disengage with the teeth around the drinking spout, thus locking or unlocking the flip-top assembly. This structure cleverly places the button and its corresponding locking mechanism inside the flip-top, ensuring the locking function while achieving a hidden button design, minimizing restrictions on the overall design of the lid and cup. Furthermore, after pressing the button to unlock, the flip-top assembly does not automatically pop open instantly; the operator must manually maintain the pressed button to open the flip-top. This eliminates the safety hazard of liquid splashing upon opening and reduces the possibility of accidental opening by young children, improving safety during use. Attached Figure Description

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0025] See Figures 1 to 6This embodiment discloses a small-mouth flip-top cup lid with a hidden button, including a connecting body 1 and a flip-top assembly 2 rotatably connected to the connecting body 1. The connecting body 1 is detachably connected to the cup body. The connecting body 1 is provided with a drinking spout 3. The drinking spout 3 on the connecting body 1 is sealed by the flip-top assembly 2. The flip-top assembly 2 includes a flip-top housing 4 rotatably mounted on the connecting body 1 on one side. A horizontally extending horizontal member 5 is provided on one side of the bottom of the flip-top housing 4. One end of the horizontal member 5 of the flip-top assembly 2 is hinged to the connecting body 1 by a pin 6. The flip-top housing 4 has a channel, and an inner liner 7 is fixedly connected to the bottom of the channel. Inside the channel, a button 8 and a rotating component 9 are arranged, abutting vertically. The button 8 can slide vertically within the channel, with its top exposed above the channel. A limiting protrusion 10 is provided at the top of the channel, and a limiting step 11 is provided on the outer circumference of the button 8. The limiting protrusion 10 blocks the limiting step 11, thus limiting the button 8 to its maximum upward sliding position within the channel. At least one vertically extending guide ridge 12 is provided on the outer circumference of the button 8 above the limiting step 11. A guide groove that mates with the guide ridge 12 is provided on the inner wall of the flip-top housing 4. The rotating part 9 is elastically supported on the inner liner 7 by the elastic part 20. The rotating part 9 is provided with a hook 14 that extends out of the inner liner 7. The drinking port 3 of the connecting body 1 is provided with a hook tooth 15 that cooperates with the hook 14. During the spiral lifting and lowering process of the rotating part 9, the hook 14 and the hook tooth 15 are engaged or disengaged.

[0026] The bottom of the rotating component 9 is provided with at least two claws 13 evenly distributed in the circumferential direction. Each claw 13 is provided with an inwardly protruding hook 14 at its bottom. The outer periphery of the drinking port 3 of the connecting body 1 is provided with at least two hook teeth 15 evenly distributed in the circumferential direction. The movement trajectory of each claw 13 is limited by the track body 16 on the inner liner 7, so that the rotating component 9 moves up and down in a spiral manner, thereby making each hook 14 at the bottom of the rotating component 9 engage with or stagger with each hook tooth 15 on the outer periphery of the drinking port 3.

[0027] The inner liner 7 includes a track body 16 and a connecting ring 17. The top of the connecting ring 17 is connected to the track body 16 by at least two connecting ribs 18 evenly distributed along the circumference. The inner liner 7 is fixedly connected to the flip cover housing 4 by the connecting ring 17. The connecting ring 17 and the flip cover housing 4 can be fixed together by adhesive or snap-fit. The number of connecting ribs 18 is equal to the number of claws 13 at the bottom of the rotating part 9, and the connecting ribs 18 and claws 13 are arranged alternately along the circumference. The track body 16 is cylindrical in shape, and a sealing ring 19 is provided at the bottom of the track body 16 to achieve a sealed connection with the drinking port 3 on the connecting body 1. The top center of the track body 16 is concave to form a central concave hole. The bottom end of the elastic element 20 is embedded in the central concave hole at the top of the track body 16. The elastic element 20 is an elastic component, such as a spring. The elastic element 20 elastically presses the rotating part 9 upward, so that the rotating part 9 and the button 8 are both in the upper limit position in the natural state.

[0028] At least two limiting grooves 21 are opened on the outer circumferential surface of the track body 16. Each limiting groove 21 is a section of groove that is spirally distributed along the outer circumferential surface of the track body 16. Each claw 13 of the rotating member 9 has an inwardly protruding sliding protrusion 22 on its inner side. The sliding protrusion 22 can be designed as a cylinder. The sliding protrusion 22 of each claw 13 of the rotating member 9 slides and engages with each limiting groove 21 in a one-to-one correspondence. The moving trajectory of the sliding protrusion 22 is limited by the limiting groove 21, thereby limiting the moving trajectory of the entire rotating member 9, so that the rotating member 9 moves up and down while rotating.

[0029] In this embodiment, the bottom of the rotating component 9 is provided with three claws 13, the drinking port 3 of the connecting body 1 is provided with three hook teeth 15, and the track body 16 is provided with three limiting grooves 21.

[0030] When the flip-top assembly 2 is closed, the hooks 14 of the three claws 13 at the bottom of the rotating part 9 engage with the three hook teeth 15 around the drinking port 3, and the drinking port 3 on the connecting body 1 is sealed by the sealing ring 19 at the bottom of the track body 16.

[0031] When it is necessary to open the flip cover assembly 2, press down on button 8. Button 8 pushes down the lower rotating component 9. Under the guidance of the three limiting slide grooves 21 on the track body 16, the sliding protrusions 22 of the three claws 13 spiral down along the spiral limiting slide grooves 21, so that the rotating component 9 spirals down as a whole. Then the hooks 14 at the bottom of the three claws 13 of the rotating component 9 disengage from the three hook teeth 15 and are circumferentially offset from the three hook teeth 15. Keep pressing down, and the flip cover assembly 2 can be opened.

[0032] The small-mouth flip-top lid provided in this embodiment cleverly integrates button 8 and its corresponding locking mechanism inside the flip cover. This ensures the locking function while achieving a concealed design for button 8, minimizing restrictions on the overall design of the lid and cup. Furthermore, after pressing button 8 to unlock, the flip cover assembly 2 does not automatically pop open instantly; the operator must manually maintain the pressed state of button 8 to open the flip cover. This eliminates the safety hazard of liquid splashing upon opening and reduces the possibility of accidental opening by young children, thus improving safety during use.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
