[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] Example 1:

[0031] like Figures 1 to 5 As shown, the present invention provides a split bottle cap, comprising a bottle body connector 1, an outer cap 2, an anti-backflow component 3, and an inner cap 4;

[0032] In this embodiment, the bottle body connector 1 is a hollow cylinder and its lower end is connected to the bottle body. The anti-backflow component 3 is arranged between the bottle body connector 1 and the inner cover 4. The lower end of the outer cover 2 is sleeved on the anti-backflow component 3 and is clamped with the inner wall of the bottle body connector 1; the outer cover 2 is arranged on the inner cover 4.

[0033] in:

[0034] The upper end of the outer wall of the bottle body connector 1 is provided with an annular clamping position 12, and the inner wall is provided with a clamping groove 11;

[0035] The bottom end of the outer cover 2 is provided with an anti-theft ring 21, and the inner wall of the top end is also formed with a hollow ring body 22;

[0036] The backflow prevention component 3 includes a piston-type backflow prevention water blocking member 31 and a water sealing link 32;

[0037] The anti-backflow water blocking member 31 is in the shape of a hat with a brim. The brim of the outer wall of the piston-type anti-backflow water blocking member 31 is formed with an annular retaining wall 311, and the inner wall thereof is formed into a cone.

[0038] like Figure 4 and Figure 5 The cam 3211 is provided with a plurality of holes 3211a and 3211b, respectively, for closing the cam 3211 and closing the cam 3211b. The cam 3211a is provided with a plurality of holes 3211b, 3211b and 3211b, respectively, for closing the cam 3211b.

[0039] like Figure 1 As shown, the inner cover 4 is formed with a cover body 41 and is provided with a fluid channel 42 and a retaining ring 43; the outer wall of the cover body 41 is also formed with an annular retaining wall 411; the top of the fluid channel (42) is provided with a fluid guide port with an oblique guide port or a rounded guide port.

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, when the present invention is assembled,

[0041] Step 1: The cone on the inner wall of the anti-backflow water blocking member 31 is adapted to its size and completely covers the four rectangular columns 32111 downward. The annular retaining wall 311 on the outer wall of the downward piston-type anti-backflow water blocking member 31 overlaps with the inner wall of the cross-shaped three-dimensional protrusion 3211 of the fluid channel 321 in the water sealing link 32, blocking the fluid from flowing downward through the fluid channel 321, forming a blockage state. The inner cover 4 is placed on the water sealing link 32, and the bottom end of the retaining ring 43 of the inner cover 4 just abuts against the outer wall of the annular platform 322 of the water sealing link 32;

[0042] The inner cover 4, the anti-backflow water blocking member 31, and the water sealing link 32 are assembled to form a combination. The cover body 41 of the inner cover 4 is arranged directly above the anti-backflow water blocking member 31. The diameter of the cover body 41 is slightly larger than the diameter of the upper half of the anti-backflow water blocking member 31. The anti-backflow water blocking member 31 can be movably inserted into the cover body 41.

[0043] Step 2: Assemble the assembly 1 formed by the inner cap 4, the anti-backflow water blocking member 31, and the water sealing link 32 with the bottle body connecting member 1, and press the assembly hard so that the thread formed on the outer wall of the lower half of the water sealing link 32 is engaged with the bottle body, and at the same time, the snap ring 43 at the bottom end of the inner cap 4 is engaged with the slot 11 on the inner wall of the bottle body connecting member 1;

[0044] The clamping ring 43 presses against the water sealing link 32, and the water sealing link 32 is clamped with the bottle body connector 1, so that the inner cover 4, the anti-backflow water blocking member 31, the water sealing link 32 and the bottle body connector 1 are cleverly assembled into a combination 2;

[0045] Step 3: Assemble the outer cap 2 onto the assembly 2 using a capping machine or hard pressing. A buckle is provided on the inner wall of the anti-theft ring 21 at the bottom end of the outer cap 2. When hard pressing is performed, the buckle is snapped into the annular snapping position 12 at the upper end of the outer wall of the bottle body connector 1 of the assembly 2. At the same time, the hollow ring 22 on the inner wall of the top end of the outer cap 2 is snapped into the inner wall of the fluid channel 42 of the inner cap 4. The hollow ring 22 guides the fluid from the fluid channel 42 into the outer cap, thereby improving the sealing performance of the bottle cap.

[0046] After these three steps, Figure 6 As shown, the present invention is assembled.

[0047] When discharging the fluid, hold the outer cover 2 and twist it clockwise to disconnect the easily broken teeth connecting the bottle body connecting cover 1 and the anti-theft ring 21. At the same time, the buckle of the outer cover is separated from the annular clamping position 12 of the bottle body connecting part 1. After twisting it off, the anti-theft ring 21 is still connected to the outer cover 2. This design not only achieves an anti-theft effect, but also provides a new anti-theft design for packaging.

[0048] Then, the present invention is turned upside down, and the fluid channel 42 of the inner cover 4 is connected to the fluid channel 321 of the water sealing link 32. The fluid flows out from the hollow cylindrical bottle connecting part 1 and enters the fluid channel 321 of the water sealing link 32.

[0049] When the present invention is inverted, the anti-backflow water blocking member 31 slides along the four rectangular columns 32111 into the cover body 41 of the inner cover 4. The anti-backflow water blocking member 31 leaves the inner wall of the cross-shaped three-dimensional protrusion 3211 of the fluid channel 321, and the blocked or clogged fluid channel 321 is opened. The fluid partially rushes into the cap-shaped anti-backflow water blocking member 31. The conical inner wall of the anti-backflow water blocking member 31 allows the fluid to flow smoothly out from the bottom end of the wide-mouthed cone.

[0050] Most of the fluid in the fluid channel 321 directly enters the inner cover 4. The fluid channel 42 of the inner cover 4 is formed around the cover body 41. When the fluid enters the cover body 41, the annular retaining wall 411 formed on the outer wall of the cover body 41 blocks the fluid, changing the flow direction of the fluid and causing the fluid to flow closer to the inner wall of the inner cover 4, thereby allowing the fluid to be slowly discharged at a uniform speed along the inner wall of the inner cover 4.

[0051] The top of the fluid channel 42 of the inner cover 4 is a fluid guide port, which can be set as an angled guide port or a rounded guide port. The best choice is the angled guide port, which has a better liquid collection effect and is not easy to overflow.

[0052] When the fluid is poured or injected into the fluid channel 42 of the inner cover 4, the fluid guide port is upward, the present invention is upward as a whole, the anti-backflow water blocking member 31 moves downward from the cover body 41, and completely covers the four rectangular columns 32111, the anti-backflow water blocking member 31 coincides with the inner wall of the cross-shaped three-dimensional protrusion 3211 of the fluid channel 321, the fluid channel 321 is blocked, and the poured or injected fluid is blocked on the cap edge of the anti-backflow water blocking member 31, thereby realizing the anti-backflow function.

[0053] The present invention is made of one or a combination of HPDE, PE, PP, PS materials or other new materials suitable for food or beverages, and the colors of the bottle body connector 1, outer cover 2, anti-backflow component 3, and inner cover 4 can be designed and matched with each other to form a combination of various colors or a solid color.

[0054] Example 2:

[0055] The present invention also provides a package comprising the split bottle cap of the first embodiment.

[0056] The above content is a further detailed description of the present invention in conjunction with specific embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
