[0003] The liquid outlet on a conventional bottle cap is usually located in the center of the bottle cap. In daily use, the user needs to hold the bottle body and tilt the bottle body at a certain angle, and the liquid inside the bottle body will flow out from the liquid outlet to complete the pouring of the liquid. When the amount of liquid in the bottle is small, it is difficult to pour out the remaining liquid by simply tilting the bottle body, resulting in liquid residue inside the bottle body, incomplete utilization, and serious waste. Or, when the user wants to pour out the remaining liquid inside the bottle body, the user needs to unscrew the bottle cap and pour it out, which is a troublesome operation. Utility Model Content

[0019] 3. Articulated part; DETAILED DESCRIPTION

[0020] The technical solution protected by the utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-2 As shown, a bottle cap for reducing liquid residue includes an upper cover 1 and a lower cover 2. The upper cover 1 and the lower cover 2 are connected by a hinge 3. The upper cover 1 can be turned over and covered on the lower cover 2 by the hinge 3. The upper cover 1 and the lower cover 2 can be closed by a buckle.

[0022] like Figure 1-2As shown, a liquid outlet 21 is eccentrically provided on the lower cover 2, and the liquid outlet 21 is located at a side of the center of the lower cover 2 away from the hinged portion 3, so as to meet people's daily usage habits and facilitate people to pour out the residual liquid in the bottle as much as possible when pouring, so as to reduce the residual liquid inside the bottle.

[0023] like Figure 1-2 As shown, the outlet 21 is correspondingly provided with a guide portion 22 which is integrally injection molded. The guide portion 22 protrudes from the upper end surface of the lower cover 2 and guides the flow path of the liquid during the pouring process. The upper cover 1 is provided with a plugging portion 11, which cooperates with the guide portion 22. When the upper cover 1 is covered on the lower cover 2, the plugging portion 11 is correspondingly inserted into the guide portion 22 to block the guide portion to ensure that when the bottle cap is closed and the bottle body is tilted or inverted, no liquid will flow out from the guide portion 22. Preferably, a soft plastic plug is correspondingly provided at the end of the plugging portion 11, and the diameter of the end of the plugging portion is adapted to the inner diameter of the guide portion to improve the sealing effect of the plugging portion 23. In the present embodiment, the upper end of the guide portion 22 is provided with a trumpet-shaped arc structure, which effectively improves the smoothness of the liquid during pouring and reduces liquid dripping.

[0024] like Figure 1-2 As shown, preferably, the height difference between the upper end of the guide portion 22 and the end surface of the lower cover 2 is not less than the distance between the side of the guide portion 22 away from the hinge portion 3 and the side of the lower cover 2 away from the hinge portion 3, so as to prevent the liquid from dripping onto the lower cover 2 during the pouring process and accumulating on the lower cover and being difficult to clean.

[0025] like Figure 1-2 As shown, a one-way air-permeable valve 24 is also provided below the lower cover 2. The one-way air-permeable valve 24 includes a valve body 242 and a valve seat 241 that are arranged in coordination. The valve body 242 is arranged above the valve seat 241, and the valve seat 241 is correspondingly engaged with the lower cover 2. The valve body 242 includes a soft protrusion that is arranged protruding toward the valve seat 241. A plane is provided at the center of the soft protrusion, and an air outlet hole is provided on the plane. A limiting plate is correspondingly provided on the valve seat 241, and the limiting plate abuts against the plane of the valve body 242 that is provided with the air outlet hole. The valve seat 241 also includes a through hole correspondingly provided on the limiting plate, and liquid flows out from the through hole. When pouring the liquid, the liquid pushes the protrusion of the valve body 242 away from the valve seat 241, and the liquid flows out from the air outlet. After the liquid is poured, the soft protrusion retreats toward the valve seat 241 under the action of pressure and abuts against the limit plate, which limits the soft protrusion. Preferably, the air outlet is correspondingly opened as a cross hole, and the limit plate is correspondingly set as a cross structure adapted to the cross hole.

[0026] like Figure 1-2As shown, a blocking portion 23 is provided below the lower cover 2 corresponding to the liquid outlet 21, and the blocking portion 23 is placed between the liquid outlet 21 and the one-way air-permeable valve 24. The blocking portion 23 includes a baffle 232 suspended below the liquid outlet through a plurality of pillars 231. The baffle 232 is correspondingly located below the liquid outlet 21, and a liquid outlet channel is formed between the baffle 232 and the liquid outlet 21, which is convenient for the liquid to flow out. During the pouring process, the baffle 232 acts as a buffer for the outflowing liquid to prevent the liquid from flowing out too much and directly gushing out of the liquid outlet. Preferably, the baffle 232 is tilted downward away from the hinge 3, so that the area of ​​the liquid outlet channel away from the hinge 3 is larger, which is more conducive to pouring the liquid inside the bottle body and reducing the liquid residue in the bottle body. When the liquid pouring angle is consistent with the tilt angle of the baffle 232, the best pouring angle is formed, at which the liquid flows out at the fastest speed and the liquid flow is the largest.

[0027] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
