Description

Technical Field

[0001] The invention relates to the field of bottle caps, and in particular to a split bottle cap. Background Art

[0002] Plastic caps are a common packaging form for bottles, cans, and barrels. The current split bottle caps are all screwed on and tightened. Because they are screw-on designs, both the bottle caps and the bottle bodies need to be thickened so that threads can be produced inside the bottle caps and on the top of the bottle bodies. Therefore, both the bottle caps and the bottle bodies require more raw materials and have higher production costs. 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 the gasket is used for sealing, the items in the bottle body will be contaminated, and when consumers use the open gasket, secondary pollution will occur. Summary of the invention

[0003] In view of this, an embodiment of the present invention provides a split bottle cap, which changes the connection method between the upper cover and the lower cover and eliminates the gasket, thereby reducing costs.

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 stuck in the slot surrounded by the protrusion 26 of the end cover 2, the end cover 1 22 and the connecting portion 25 to complete the connection. The side cover 1 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 present invention 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 to play 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, and 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 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 includes an upper side cover 121 and a lower side cover 122, the lower side cover 122 is an annular structure, the upper side cover 121 is a truncated cone structure, and the top diameter of the upper side cover 121 is smaller than the bottom diameter of the lower side cover 122. The structural design of the upper cover can reduce the volume of the upper cover, thereby reducing the weight of the upper cover and reducing product costs.

[0042] In one embodiment of the present invention, a plurality of circumferentially distributed 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 the friction force 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 Fig.10 As shown, the top cover of the upper cover 1 is an arc-shaped structure, and the center of the top cover is the lowest point. If the contents of the bottle need to be drained or poured out, the bottle needs to be inverted. Only when the edge of the top cover 11 of the upper cover 1 contacts the desktop or tabletop can the inverted bottle be stable. If the top cover 11 is a flat surface, the inverted bottle may be unstable due to protrusions on the desktop or tabletop.

[0045] In another embodiment of the present invention, Fig.12 and Fig.13 As shown, the inner side of the lower end of the side cover 11 is provided with a plurality of circumferentially distributed support columns 17, which play a role of pressing the cover, and are convenient for using the manufacturer's tooling and pressing the cover. If the support columns 17 are not designed, since the middle of the lower cover is relatively thin, if the support columns are not designed, when pressing the cover, the lower cover will be deformed due to the downward pressure of the buckle 1, resulting in the buckle 1 not being able to be pressed into the slot surrounded by the protrusion 26, the end cover 1 22 and the connecting part 25. After the support columns 17 are designed, the lower cover is prevented from being deformed, so that the buckle 1 can be easily pressed into the slot. The support columns 17 are located at the upper end of the buckle 13, and the support columns 17 and the buckle 13 are spaced apart.

[0046] The top of the liquid outlet 24 is provided with an outwardly facing flange 244 , and the flange 244 enables the liquid outlet 24 to form a seal with 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 substitutions, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
