Description

Technical Field

[0001] This utility model relates to the field of cups, and in particular to a cup lid with a stable venting structure. Background Technology

[0002] Existing cups or bottles are generally sealed with threaded stoppers or solid rubber stoppers, which is inconvenient in daily use. In cups with rubber stoppers, when the cup is closed, the rubber stopper contacts the inner wall of the cup. When the rubber stopper slides, a negative pressure is formed inside the cup, which makes it take more time and effort to close the lid.

[0003] Comparing with patent publication number CN104803085B, a container stopper for quick opening and closing includes a cylindrical stopper body, which includes a stopper rod. The bottom of the stopper rod is provided with a base that can be inserted into or pulled out of the container. The shape and size of the base are matched with the shape and size of the straight section of the container opening or the smallest cross-section of the container. An annular stopper body is provided on the upper part of the base. A flexible and deformable elastic sealing sleeve is provided between the annular stopper body and the base. Both the annular stopper body and the base can move relative to each other along the axial direction of the container opening under the action of external force to squeeze the elastic sealing sleeve, causing the elastic sealing sleeve to expand radially and bend outward to form a sealing ring between the container and the base. The sealing ring, together with the base, forms a sealing layer that enables the container to close quickly. During the closing process, the elastic sealing sleeve expands and contacts the inner wall of the container. When the stopper rod is pulled out, a negative pressure is formed inside the container, making it more time-consuming and laborious to pull out the stopper rod. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a cup lid with a stable venting structure, which solves the problem of time-consuming and laborious cup lid closing.

[0005] The technical solution adopted by this utility model is as follows: a cup lid with a stable venting structure, including a fixed shell and a movable plug. A limiting plate is provided at the bottom of the movable plug. An elastic sealing sleeve is abutted between the limiting plate and the fixed shell. An clearance opening is provided on the fixed shell. The movable plug is slidably connected in the clearance opening. A sealing device is slidably connected on the movable plug. A first elastic element for driving the sealing device upward is provided on the movable plug. A vent hole is provided on the limiting plate. The sealing device includes a sealing plug. The sealing device passes through the vent hole and is located below the vent hole. A knob is rotatably connected to the movable plug. The knob includes a side lug. An arc-shaped ramp is provided at the bottom of the knob. The sealing device includes a protrusion. The protrusion is located below the arc-shaped ramp. The cup lid can switch between a sealing state and a venting state. When in the sealed state, the side ear extends beyond the outline of the clearance opening, the protrusion is close to the upper end of the arc-shaped slope, the elastic sealing sleeve bulges outward, and the sealing plug seals the vent hole; When in the ventilated state, the side ear is located within the clearance opening, the protrusion is close to the lower end of the arc-shaped slope, and a gap is left between the sealing plug and the vent.

[0006] With the above technical solution, when the user opens the lid, turning the knob to the outline of the clearance opening compresses the first elastic element, the elastic sealing sleeve moves towards the center, the protrusion gradually moves away from the upper end of the arc-shaped slope, and the sealing plug disengages from the vent hole. When the lid is opened again, the vent hole inside the cup body can be connected, keeping the air pressure inside the cup body and the air pressure inside the vent hole balanced, making it convenient for the user to open the lid. When the user closes the lid, when the movable plug moves to the upper limit of the clearance opening and the side ear is within the outline range of the clearance opening, there is always a gap between the sealing plug and the vent hole, which facilitates the balance of air pressure inside the lid and the cup body, making the closing process smoother and less strenuous. When the side ear exceeds the outline range of the clearance opening, the sealing plug can seal the vent hole to prevent water leakage.

[0007] Furthermore, the movable plug is provided with a first connecting post, and the knob is provided with a second connecting post. A second elastic element is connected to the first connecting post and the second connecting post. During the process of the sealing device switching from the sealing state to the ventilating state, the second elastic element extends and tightens.

[0008] With the above technical solution, the second elastic element is in a stretched state during the user's opening process. When the cup lid is closed, the second elastic element resets, causing the knob to rotate and the side ear to rotate beyond the contour range of the avoidance opening. The sealing plug seals the vent hole, making it more convenient for the user. When the lid is closed, the sealing plug can automatically seal the vent hole.

[0009] Furthermore, the upper end of the arc-shaped ramp is provided with a limiting surface, which limits the protrusion.

[0010] The above technical solution, with the limiting surface abutting against the protrusion, can prevent the knob from rotating too much, limit the knob's rotation stroke, reduce wasted effort during the opening process, and make the usage efficiency higher.

[0011] Furthermore, the sealing device includes a movable rod, the upper end of which passes through the knob.

[0012] With the above technical solution, the user can press the movable rod before opening the lid to release the sealing plug from the vent hole, so that the air pressure inside the cup body and the air pressure inside the vent hole are balanced, making it convenient for the user to open the lid.

[0013] Furthermore, the sealing device is provided with a limiting block, and the movable plug body is provided with a sliding groove, and the limiting block is slidably connected in the sliding groove.

[0014] Through the above technical solution, the limiting block slides within the groove, enabling the movable plug to circumferentially limit the sealing device.

[0015] Furthermore, the movable plug body includes a movable block and a cover shell, the cover shell is provided with a hook, the movable block is provided with a corresponding snap-fit ​​groove, and the hook engages with the snap-fit ​​groove.

[0016] The above technical solution allows for the detachable connection of the cover and the movable block, facilitating the assembly of internal components.

[0017] Furthermore, the fixed shell is provided with an outer handle, the movable plug is provided with an inner handle, and the inner side of the outer handle is provided with a groove that is adapted to the inner handle.

[0018] With the above technical solution, when closing the lid, the user can simply lift the inner handle into the groove to close the lid, making it more convenient to use. Attached Figure Description

[0024] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9A cup lid with a stable venting structure includes a fixed shell 1 and a movable plug 2. A limiting plate 201 is provided at the bottom of the movable plug 2. An elastic sealing sleeve 3 is abutted between the limiting plate 201 and the fixed shell 1. An clearance opening 102 is provided on the fixed shell 1. The movable plug 2 is slidably connected within the clearance opening 102. A sealing device 4 is slidably connected on the movable plug 2. A first elastic element 6 for driving the sealing device 4 upward is provided on the movable plug 2. A vent hole 2011 is provided on the limiting plate 201. The sealing device 4 includes a sealing plug 401. The sealing device 4 passes through the vent hole 2011 and is located below the vent hole 2011. A knob 5 is rotatably connected to the movable plug 2. The knob 5 includes a side ear 501. An arc-shaped ramp 502 is provided at the bottom of the knob 5. The sealing device 4 includes a protrusion 402. The protrusion 402 is located below the arc-shaped ramp 502. The cup lid can switch between a sealed state and a venting state. When in a sealed state, the side ear 501 extends beyond the outline of the clearance opening 102, the protrusion 402 approaches the upper end of the arc-shaped slope 502, the elastic sealing sleeve 3 bulges outward, and the sealing plug 401 seals the vent 2011. When in the ventilated state, the side ear 501 is located inside the clearance opening 102, the protrusion 402 is close to the lower end of the arc-shaped ramp 502, and there is a gap between the sealing plug 401 and the vent 2011.

[0025] When the user opens the lid, they turn the knob (5) to the outline of the clearance opening (102), compressing the first elastic element (6), causing the elastic sealing sleeve (3) to move towards the center, and the protrusion (402) to gradually move away from the upper end of the arc-shaped slope (502). The sealing plug (401) disengages from the vent (2011), allowing the vent (2011) inside the cup body (8) to connect when the lid is opened again, thus maintaining a balance between the air pressure inside the cup body (8) and the air pressure inside the vent (2011), making it convenient for the user to open the lid; When the user closes the lid, the movable plug (2) moves to the upper limit of the clearance opening (102) and the side ear (501) is within the outline range of the clearance opening (102). There is always a gap between the sealing plug (401) and the vent (2011), which facilitates the balance of air pressure inside the lid and the cup body (8), making the closing process smoother and less strenuous. When the side ear (501) exceeds the outline range of the clearance opening (102), the sealing plug (401) can seal the vent (2011) to prevent water leakage.

[0026] The cup body 8 is provided with a snap-fit ​​part 801. When sealed, the elastic sealing sleeve 3 abuts against the snap-fit ​​part 801.

The first connecting post 203 and the second connecting post 503 are connected to a second elastic element 7. During the process of the sealing device 4 switching from the sealing state to the ventilating state, the second elastic element 7 extends and tightens.

[0029] During the user's opening of the lid, the second elastic element 7 is in a stretched state. When the lid is closed, the second elastic element 7 resets, causing the knob 5 to rotate and the side ear 501 to rotate beyond the contour range of the avoidance opening 102. The sealing plug 401 seals the vent hole 2011, making it more convenient for the user. When the lid is closed, the sealing plug 401 automatically seals the vent hole 2011.

[0030] The second elastic element 7 is preferably a spring.

[0031] See Figure 9 The upper end of the arc-shaped ramp 502 is provided with a limiting surface 5021, which limits the protrusion 402.
