Description

Technical Field

[0001] This utility model relates to the technical field of cup lids, and in particular to a direct drinking lid with an anti-reverse function. Background Technology

[0002] There is a type of direct drinking cover in the existing technology, which includes a main body, a direct drinking spout, and a cover that covers the direct drinking spout. Because the cover and the direct drinking spout are connected by threads, when the water cup is put in a bag and carried out, the cover is easy to bump into objects and fall back, which makes the cover loose and affects the sealing effect at the direct drinking spout, thus causing water leakage. Therefore, this needs to be improved. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies where the top cover and drinking spout are threaded together, making it prone to slippage and causing the top cover to loosen, leading to water leakage at the drinking spout. It provides a new drinking spout with an anti-slip function.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] A direct drinking cap with an anti-reverse function includes a main cap, a direct drinking spout, and a top cap. The top cap covers the direct drinking spout and is threadedly connected to it. The cap also includes a flap rotatably mounted on the main cap. The top cap is rotatably mounted on the flap. The inner wall of the flap is provided with a first locking tooth, and the outer surface of the top cap is provided with a second locking tooth. The top cap is inserted into the flap, and the first locking tooth and the second locking tooth engage with each other. The flap causes the top cap to flip away from or towards the direct drinking spout.

[0006] The top cover is locked onto the flap by the interlocking of the first and second locking teeth. On the one hand, this improves the stability of the connection between the top cover and the flap. On the other hand, when the top cover is hit by an external object, it is less likely to rotate, thus preventing the top cover from rolling back. This improves the stability of the top cover when screwed onto the drinking spout and the sealing effect on the drinking spout.

[0007] Preferably, in the above-described direct drinking cap with anti-reverse function, the first locking tooth includes a plurality of first teeth arranged in a ring, and the second locking tooth includes second teeth corresponding one-to-one with the first teeth. The upper end of the first tooth has an inclined surface, and the inner end of the inclined surface gradually slopes downward inward. The lower end of the second tooth is provided with a relief arc surface, and the width of the relief arc surface gradually decreases upward along the height direction. The second tooth slides inward along the inclined surface through the relief arc surface and engages with the first tooth.

[0008] By cooperating with the inclined surface and the yielding arc surface, the obstruction and interference encountered when the second tooth rotates into the adjacent first tooth are reduced, thereby improving the stability of the engagement of the first locking tooth and the second locking tooth.

[0009] Preferably, in the above-described direct drinking cap with anti-reverse function, the spacing between adjacent first teeth gradually increases inward along the horizontal direction, the outer end of the second tooth is arc-shaped, and the width of the second tooth gradually increases inward along the horizontal direction.

[0010] The above structure improves the smoothness of the second tooth tip, further enhancing the smoothness of the meshing between the second and first teeth.

[0011] Preferably, in the above-described direct drinking cap with anti-reverse function, a limiting ring groove is formed on the lower outer surface of the cap, the second locking tooth is disposed in the limiting ring groove and abuts against the top inner wall of the limiting ring groove, the inner walls at both ends of the limiting ring groove abut against or separate from the end of the first locking tooth as the cap rotates; and the upper outer surface of the cap is provided with anti-slip texture.

[0012] The interaction between the first locking tooth and the limiting ring groove not only allows the top cover to rotate on the flip plate, but also limits the distance the top cover moves on the flip plate, preventing the top cover from coming off the flip plate when it is rotated out of the drinking spout. At the same time, it also makes it easier for the top cover to drive the flip plate to flip out of the drinking spout simultaneously. The anti-slip texture increases the friction coefficient of the top cover, preventing the user from slipping when rotating the top cover.

[0013] Preferably, in the above-described direct drinking cap with anti-reverse function, the main cap has an arc-shaped recessed groove, and a rotating shaft is installed in the arc-shaped recessed groove. The flap includes a connecting plate and a sleeve. The first locking tooth is disposed on the inner wall of the sleeve. The connecting plate is connected to the rotating shaft and rotates around the rotating shaft in the height direction. The sleeve rotates with the connecting plate and is fitted onto the direct drinking spout or exits from the direct drinking spout. The lower surface of the connecting plate near the rotating shaft has an upwardly arched clearance groove.

[0014] When the sleeve is fitted onto the drinking spout, it achieves alignment between the top cover and the drinking spout, making it easier to screw the top cover onto the drinking spout. On the other hand, it makes it difficult for the sleeve to rotate out of the drinking spout, further improving the stability of the top cover fixed at the drinking spout. The arc-shaped recess and clearance groove reduce interference between the connecting plate and the main cover when rotating, improving the smoothness of the flip-top rotation.

[0015] Preferably, in the above-described direct drinking cap with anti-reverse function, the outer surface of the rotating shaft is provided with abutting teeth, and the connecting plate is provided with a connecting hole for insertion and engagement with the rotating shaft, wherein the abutting teeth abut against the inner wall of the connecting hole.

[0016] The teeth increase the tightness of the connection between the rotating shaft and the connecting hole, thus improving the stability of the flap rotation setting on the main cover.

[0017] Preferably, in the above-mentioned direct drinking cap with anti-reverse function, the connecting plate is provided with a positioning groove, the arc-shaped recess is provided with a positioning protrusion, the flip plate flips outward so that the connecting plate is in contact with the upper surface of the main cap, and the positioning protrusion is inserted into the positioning groove for interlocking.

[0018] The positioning groove and positioning protrusion work together to keep the flap in an outward-flipped state, preventing the flap from flipping back and hitting the user's face when drinking water through the drinking spout, thus making it more convenient to use.

[0019] Preferably, the above-described direct drinking cap with anti-reverse function has a flow channel communicating with the direct drinking port and a heat insulation cavity surrounding the flow channel, wherein a heat insulation body is provided in the heat insulation cavity.

[0020] The heat insulation cavity and heat insulation body can insulate the flow channel, making it easier for users to hold the drinking cap. Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the present invention: Example

[0027] like Figures 1-4As shown, a direct drinking cap with an anti-reverse function includes a main cap 1, a direct drinking spout 2, and an upper cap 3. The upper cap 3 covers the direct drinking spout 2 and is threadedly connected to the direct drinking spout 2. It also includes a flap 4 rotatably mounted on the main cap 1. The upper cap 3 is rotatably mounted on the flap 4. The inner wall of the flap 4 is provided with a first locking tooth 5, and the outer surface of the upper cap 3 is provided with a second locking tooth 6. The upper cap 3 is inserted into the flap 4, and the first locking tooth 5 and the second locking tooth 6 engage with each other. The flap 4 drives the upper cap 3 to flip away from or towards the direct drinking spout 2.

[0028] Preferably, the first locking tooth 5 includes a plurality of first teeth 51 arranged in a ring, and the second locking tooth 6 includes a second tooth 61 corresponding to the first tooth 51. The upper end of the first tooth 51 has an inclined surface 52, and the inner end of the inclined surface 52 gradually slopes downward inward. The lower end of the second tooth 61 is provided with a relief arc surface 62, and the width of the relief arc surface 62 gradually decreases upward along the height direction. The second tooth 61 slides inward along the inclined surface 52 through the relief arc surface 62 and meshes with the first tooth 51.

[0029] Preferably, the spacing between adjacent first teeth 51 gradually increases inward along the horizontal direction, the outer end of the second tooth 61 is arc-shaped, and the width of the second tooth 61 gradually increases inward along the horizontal direction.

[0030] Preferably, a limiting annular groove 31 is formed on the lower outer surface of the upper cover 3, and the second locking tooth 6 is disposed in the limiting annular groove 31 and abuts against the top inner wall of the limiting annular groove 31. The inner walls at both ends of the limiting annular groove 31 abut against or separate from the end of the first locking tooth 5 as the upper cover 3 rotates. The upper outer surface of the upper cover 3 is provided with anti-slip texture 32.

[0031] Preferably, the main cover 1 has an arc-shaped recess 11, and a rotating shaft 7 is installed in the arc-shaped recess 11. The flap 4 includes a connecting plate 41 and a sleeve 42. The first locking tooth 5 is provided on the inner wall of the sleeve 42. The connecting plate 41 is connected to the rotating shaft 7 and rotates around the rotating shaft 7 in the height direction. The sleeve 42 rotates with the connecting plate 41 and is fitted onto the drinking spout 2 or exits from the drinking spout 2. The lower surface of the connecting plate 41 near the rotating shaft 7 has an upwardly arched clearance groove 411.

[0032] Preferably, the outer surface of the rotating shaft 7 is provided with abutting teeth 71, and the connecting plate 41 is provided with a connecting hole 412 for insertion and engagement with the rotating shaft 7, and the abutting teeth 71 abut against the inner wall of the connecting hole 412.

[0033] Preferably, the connecting plate 41 is provided with a positioning groove 413, and the arc-shaped recess 11 is provided with a positioning protrusion 111. The flip piece 4 flips outward so that the connecting plate 41 is in contact with the upper surface of the main cover 1, and the positioning protrusion 111 is inserted into the positioning groove 413 for insertion and engagement.

[0034] Preferably, the main cover 1 has a flow channel 12 communicating with the drinking spout 2 and a heat insulation cavity 13 surrounding the flow channel 12, and a heat insulation body 131 is provided in the heat insulation cavity 13.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the drinking spout 2 is located on the right side of the main cover 1 and the upper end of the drinking spout 2 is inclined outward. The drinking spout 2 has a first thread inside. The upper cover 3 includes an inner layer and an outer layer arranged coaxially. The outer wall of the inner layer has a second thread that mates with the first thread. The inner layer is inserted into the drinking spout 2 and is threadedly connected by the mutual engagement of the first thread and the second thread. The drinking spout 2 is inserted between the inner layer and the outer layer.

[0036] like Figure 2 As shown, the inner wall of the inner layer has four spaced reinforcing ribs extending along the height direction, thereby improving the structural strength of the inner layer. The top inner wall of the top cover 3 has a gasket, which is located between the inner and outer layers and is used to abut against the end of the drinking spout 2, thereby improving the tightness of the top cover 3 when it is closed at the drinking spout 2.

[0037] like Figures 1-4 As shown, the first locking teeth 5 are distributed in a ring on the upper inner wall of the sleeve 42. The first locking teeth 5 are inserted into the limiting ring groove 31 and abut against the top or bottom wall of the limiting ring groove 31 as the upper cover 3 rotates. This not only makes it difficult for the upper cover 3 to come off the flip piece 4, but also limits the number of rotations of the upper cover 3, making it easy to tighten the upper cover 3 precisely at the drinking spout 2 or remove it from the drinking spout 2.

[0038] The drinking spout 2 and the flow channel 12 are located on the right side of the main cover 1. The main cover 1 has a handle on the left side. The handle and the flow channel 12 are located on both sides of the heat insulation cavity 13. The heat insulation body 131 is made of heat insulation material. The heat insulation body 131 is square and has multiple honeycomb holes. Thus, the heat insulation cavity 13 and the heat insulation body 131 can insulate the handle and prevent scalding, making it convenient for users to hold the handle or the main cover 1.

[0039] More specifically, when it is necessary to close the drinking spout 2, the flap 4 is flipped to the right side of the main cover 1 until the sleeve 42 is fitted onto the drinking spout 2. Then, while rotating the upper cover 3 in the locking direction, the upper cover 3 is pressed down. As the upper cover 3 gradually moves down, the second tooth 61 slides into the space between the adjacent first tooth 51 through the clearance arc surface 62 along the inclined surface 52. At this time, the first locking tooth 5 and the second locking tooth 6 mesh, the top wall of the limiting ring groove 31 abuts against the upper end of the sleeve 42, and the upper cover 3 is tightened at the drinking spout 2, thereby achieving the closure of the drinking spout 2.

[0040] The mutual engagement of the first locking tooth 5 and the second locking tooth 6 restricts the rotation direction of the upper cover 3, making it less likely for the upper cover 3 to rotate when it is hit by an external object, thus preventing the upper cover 3 from retracting and improving the stability of the upper cover 3 when screwed onto the drinking spout 2.

[0041] When you need to drink water through the drinking port 2, first turn the top cover 3 in the unlocking direction. At this time, the top cover 3 moves upward along the first thread. When the bottom of the limiting ring groove 31 abuts against the lower end of the first locking tooth 5, the top cover 3 is unscrewed from the drinking port 2. Then, flip the top cover 3 to the left of the main cover 1 to drive the sleeve 42 out of the drinking port 2, and the user can drink water through the drinking port 2.

[0042] Because the arc-shaped recess 11 has a positioning protrusion 111, when the flip plate 4 is flipped to the left and attached to the upper surface of the main cover 1, the positioning protrusion 111 is inserted into the positioning groove 413, which can lock and limit the flip plate 4, so that the flip plate 4 is kept in the left-flipped state, preventing the flip plate 4 from rotating back and hitting the user when drinking water.

[0043] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
