[0002] Plastic caps are a common packaging form for bottles, cans, and barrels. Current split bottle caps are all screwed on. Because they are screw-on caps, both the bottle cap and the bottle body need to be thickened so that threads can be produced inside the bottle cap and on the top of the bottle body. Therefore, both the bottle cap and the bottle body require more raw materials and the production cost is high. For some bottle caps, a tight seal is required, so a gasket needs to be set on the top of the bottle body. However, when using the gasket for sealing, it will contaminate the items in the bottle body, and when consumers use it to open the gasket, it will cause secondary pollution. Utility Model Content

[0033] As shown in the figure, the embodiment of the utility model discloses a split bottle cap, including an upper cover 1 and a lower cover 2, the upper cover 1 and the lower cover 2 are both rotating bodies, the upper cover 1 includes a top cover 11 and a side cover 12, the top cover 11 is arranged on the top of the side cover 12, the inner side of the lower end of the side cover 12 is provided with a plurality of circumferentially distributed buckles 13, an upper inner plug 14 is provided at the middle of the lower end of the top cover 11, the lower cover 2 includes a side cover 21, an end cover 12, an end cover 23 and a liquid outlet 24, the end cover 12 and the end cover 23 are annular, and the outer side of the end cover 22 is connected to the side cover 12. The top of the second cover 21 is connected, and the inner side of the first end cover 22 is provided with a connecting portion 25, which connects the first end cover 22 and the second end cover 23. The second end cover 23 is located at the upper end of the first end cover 22. The outer side of the second end cover 23 is provided with a protrusion 26. The liquid outlet 24 is connected to the middle of the second end cover 23. When the upper cover 1 is connected to the lower cover 2, the top of the upper inner plug 14 is located in the liquid outlet 24, and the liquid outlet 24 is connected to the internal space of the second side cover 21. The buckle 13 is located in the slot surrounded by the protrusion 26 of the second end cover, the first end cover 22, and the connecting portion 25. When the upper cover 1 is connected to the lower cover 2, the upper cover 1 is pressed, and the buckle 13 of the upper cover is locked in the slot surrounded by the protrusion 26 of the second end cover, the first end cover 22, and the connecting portion 25, completing the connection. The side cover 12 of the upper cover and the side cover 2 21 of the lower cover 2 do not need to be designed with threads, so the overall design can be thinner than the traditional upper cover and lower cover, reducing product costs, and no screw cap is required, which is convenient for consumers to use.

[0034] The upper cover and the lower cover of the utility model are easy to connect, and the gasket is eliminated, which reduces costs and avoids secondary contamination when consumers use it. The secondary contamination here refers to the risk of secondary contamination when the upper cover is opened for the first time and the gasket is torn off.

[0035] The liquid in the bottle is poured out from the liquid outlet 24. The upper inner plug 14 of the upper cover 1 blocks the liquid outlet 24 and plays a sealing role.

[0036] In one embodiment of the present invention, the liquid outlet 24 includes a side cover three 241, an end cover three 242 and a liquid outlet pipe 243. The side cover three 241 is arranged in the middle of the end cover two 23, the end cover three 242 is arranged on the top of the side cover three 241, and the bottom of the liquid outlet pipe 243 is arranged in the middle of the end cover three 241.

[0037] In one embodiment of the present invention, the outer diameter of the second side cover 21 is larger than the outer diameter of the connecting portion 25, and the outer diameter of the connecting portion 25 is larger than the outer diameter of the third side cover 241. The outer side of the second side cover 21 does not need to be designed with threads.

[0038] In one embodiment of the present invention, the liquid outlet pipe 243 is a truncated cone structure, and the top diameter of the liquid outlet pipe 243 is smaller than the bottom diameter of the liquid outlet pipe. The truncated cone structure design of the liquid outlet pipe 243 allows the upper end of the liquid outlet pipe 243 to be sealed with the upper inner plug 14.

[0039] In one embodiment of the present invention, the top cover 11 of the upper cover is provided with a sealing ring 15, which is located on the outside of the upper inner plug 14. When the upper cover 1 is connected to the lower cover 2, the top of the liquid outlet pipe 243 is located between the sealing ring 15 and the upper inner plug 14.

[0040] In one embodiment of the present invention, Figure 8 The lower cover 2 is provided with a lower inner plug 27, which is located at the lower end of the end cover 1 22. The bottle mouth of the bottle body is clamped between the lower inner plug 27 and the side cover 21. The side cover 21 is provided with a second buckle 28, which clamps the bottle mouth. The buckle 28 here is annular.

[0041] In one embodiment of the present invention, the side cover 12 of the upper cover comprises an upper portion 121 and a lower portion 122. The lower portion 122 is an annular structure, while the upper portion 121 is a frustum. The top diameter of the upper portion 121 is smaller than the bottom diameter of the lower portion 122. This structural design of the upper cover can reduce the volume of the upper cover, thereby reducing the weight of the upper cover and lowering the product cost.

[0042] In one embodiment of the present invention, a plurality of anti-slip strips 16 are provided on the outer side of the side cover 11 of the upper cover. The design of the anti-slip strips 16 increases friction and facilitates opening the upper cover.

[0043] In one embodiment of the present invention, the anti-slip strip 16 includes two symmetrical straight strips 161 and a curved strip 162 connecting the two straight strips.

[0044] In one embodiment of the present invention, Figure 8 or Figure 10 As shown, the top cover 1 of the upper cover is an arc-shaped structure, with the center of the top cover being the lowest point. To drain or empty the contents of the bottle, the bottle needs to be inverted. Only when the edge of the top cover 11 of the upper cover 1 is in contact with the table or countertop can the bottle be inverted stably. If the top cover 11 is flat, it may become unstable due to protrusions on the table or countertop.

[0045] In another embodiment of the present invention, Figure 12 and Figure 13 As shown, the inner side of the lower end of side cover 11 is provided with several circumferentially distributed support columns 17, which act as a pressure cap and facilitate the use of manufacturer tooling and pressure capping. Without the support columns 17, the lower cover is relatively thin in the middle. If the support columns are not provided, when the pressure cap is pressed, the lower cover will be deformed by the downward pressure of buckle 1, resulting in buckle 1 not being able to press into the slot surrounded by protrusion 26, end cover 1 22, and connecting portion 25. The design of support columns 17 prevents the lower cover from deforming, making it easy to press buckle 1 into the slot. Support columns 17 are located at the upper end of buckle 13, and support columns 17 are spaced apart from buckle 13.

[0046] An outwardly facing flange 244 is provided at the top of the liquid outlet 24 , and the flange 244 forms a seal between the liquid outlet 24 and the upper cover.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
