[0023] Example: Figure 1-4The anti-overflow bottle cap shown is used in conjunction with a bottle body. The anti-overflow bottle cap comprises a cover body 1 and a cap 2. The cap 2 is arranged on one side of the top of the cover body 1 and can be rotated with the connection between the cover body 1 and the cover body 1 as the axis to cover or detach from the cover body 1. The cover body 1 has a screwing cavity 101, a giveway groove 102 and an anti-overflow groove 103. The screwing cavity 101 opens at the bottom of the cover body 1, and the giveway groove 102 opens at the top and the circumferential side of the cover body 1. The giveway groove 102 has two anti-overflow parts 104 arranged opposite to each other in the circumferential direction of the cover body 1. The anti-overflow groove 103 opens at the top of the cover body 1. The anti-overflow groove 103 extends from one anti-overflow part 104 to the other anti-overflow part 104 in the circumferential direction of the cover body 1 to form a guide platform 105 on the top of the cover body 1. The guide platform 105 is provided with a liquid outlet 106 communicated with the screwing cavity 101, and the cover body 1 is provided with an external connecting belt 3 connected to the cap 2 on the opposite sides of the giveway groove 102. When the anti-overflow bottle cap is used in conjunction with the bottle body, the bottle body is inserted into the anti-overflow bottle cap from the screwing cavity 101 and is threadedly connected to the anti-overflow bottle cap on the wall of the screwing cavity 101. The bottle body has a liquid containing cavity connected to the screwing cavity 101. This embodiment provides an anti-overflow bottle cap to solve the problem that the existing bottle cap used on bottles containing highly fluid liquids lacks an anti-overflow structure, and when the user pours out the liquid and straightens the bottle, the overflowing residual liquid falls down along the outer wall of the cover body 1 to cause pollution. The main method is to configure a guide platform 105 connected to the screwing cavity 101 through a liquid outlet 106 at the top of the cover body 1 and to set an anti-overflow groove 103 on the outer ring of the guide platform 105, so that when the user pours out the liquid and straightens the bottle, the overflowing residual liquid can be collected into the anti-overflow groove 103 through the guide platform 105, thereby preventing the overflowing residual liquid from falling down along the outer wall of the cover body 1 to cause pollution. Furthermore, since the cover body 1 has a clearance groove 102, the clearance groove 102 has two sides of the overflow-stopping parts 104 opposite to each other, the cap 2 is connected to the opposite sides of the clearance groove 102, and the anti-overflow groove 103 extends from one overflow-stopping part 104 to the other overflow-stopping part 104, thereby preventing the anti-overflow groove 103 from overflowing at the connection between the cover body 1 and the cap 2, and the structure is compact and reasonable.

[0024] In the embodiment of the utility model, a guide channel 107 connecting the anti-overflow groove 103 and the screwing chamber 101 is formed on the cover body 1, and the guide channel 107 is connected to the anti-overflow groove 103 through the liquid inlet 108, and the aperture of the liquid inlet 108 is smaller than the aperture of the liquid outlet 106. The above arrangement allows the residual liquid entering the anti-overflow groove 103 to flow back into the bottle by configuring the guide channel 107 connecting the anti-overflow groove 103 and the screwing chamber 101 on the cover body 1, so as to avoid the residual liquid accumulated in the anti-overflow groove 103 from overflowing when the user operates it next time, causing pollution to the outer wall of the cover body 1, and avoiding waste at the same time; and because the aperture of the liquid inlet 108 is smaller than the aperture of the liquid outlet 106, it is prevented that the liquid in the bottle overflows through the liquid inlet 108 when the user pours out the liquid.

[0025] In the embodiment of the utility model, the bottom of the anti-overflow groove 103 is inclined downward from left to right, and the liquid inlet 108 is arranged at the lower right bottom of the bottom of the anti-overflow groove 103. The above arrangement is configured to be inclined downward from left to right, and the liquid inlet 108 is arranged at the lower right bottom of the bottom of the anti-overflow groove 103, so that the excess liquid can be gathered and refluxed.

[0026] In the embodiment of the utility model, the guide channel 107 is inclined from top to bottom toward the axis of the cover body 1, and the inner diameter of the guide channel 107 gradually increases from top to bottom. The above arrangement is configured to be inclined from top to bottom toward the axis of the cover body 1, and the inner diameter of the guide channel 107 gradually increases from top to bottom, which facilitates the reflux of residual liquid and prevents the liquid in the bottle from overflowing from the liquid inlet 108.

[0027] In the embodiment of the utility model, the overflow prevention groove 103 has an inner annular wall 109 and an outer annular wall 110 which are arranged opposite to each other in the radial direction of the cover body 1, the inner annular wall 109 is close to the inside, the outer annular wall 110 is close to the outside, the setting height of the inner annular wall 109 is not higher than the setting height of the outer annular wall 110, and the setting height of the overflow stop portion 104 is flush with the setting height of the inner annular wall 109. Since the setting height of the inner annular wall 109 is not higher than the setting height of the outer annular wall 110, and the setting height of the overflow stop portion 104 is flush with the setting height of the inner annular wall 109, the residual liquid is prevented from overflowing the overflow prevention groove 103 and dripping along the outer wall of the cover body 1.

[0028] In the embodiment of the utility model, the middle part of the flow guide platform 105 bulges upward to form a convex part 111, the convex part 111 is hemispherical, and a liquid outlet 106 is formed on the convex part 111. Since the middle part of the flow guide platform 105 bulges upward to form the hemispherical convex part 111, and the liquid outlet 106 is provided on the convex part 111, it is convenient for the residual liquid to slide into the anti-overflow groove 103.

[0029] In the embodiment of the utility model, the cap 2 is provided with a sealing column 201 that matches the shape of the liquid outlet 106. When the cap 2 is covered on the cover body 1, the sealing column 201 is at least partially inserted into the liquid outlet 106. The above arrangement improves the sealing performance when the cap 2 covers the cover body 1 by providing the sealing column 201 on the cap 2 that is plugged and matched with the liquid outlet 106 to block the liquid outlet 106 when the cap 2 covers the cover body 1.

[0030] In the embodiment of the utility model, the cover body 1 is provided with a lower stop ring 113 arranged outside the liquid outlet 106, and the cap 2 is provided with an upper stop ring 202 arranged outside the sealing column 201. When the cap 2 is covered on the cover body 1, the upper stop ring 202 abuts against the lower stop ring 113. The above arrangement is conducive to improving the sealing performance when the cap 2 covers the cover body 1.

[0031] In the embodiment of the utility model, the cap 2 is provided with an inner connecting strip 4 extending from the cap 2 to the bottom of the clearance groove 102. The above arrangement makes the cap 2 and the cover body 1 firmly connected by configuring the inner connecting strip 4 extending from the cap 2 to the bottom of the clearance groove 102 on the cap 2.

[0032] In the embodiment of the utility model, the flow guide channel 107 is connected to the screwing chamber 101 through the lower leak 115, and the wall of the screwing chamber 101 is provided with an inner stop ring 116, and the lower leak 115 is located above the inner stop ring 116. The inner stop ring 116 is inserted into the bottle mouth of the bottle body when the anti-overflow bottle cap is connected to the bottle body, and the inner stop ring 116 matches the shape of the bottle mouth of the bottle body. The above arrangement improves the sealing performance of the connection between the anti-overflow bottle cap and the bottle body by configuring the inner stop ring 116 on the wall of the screwing chamber 101 to be plugged into and matched with the bottle mouth when the anti-overflow bottle cap is connected to the bottle body.
