[0060] In the embodiment, the paper bottle body assembly 10 comprises a first paper bottle body 13, a second paper bottle body 14, a paper bottle mouth piece 15, and a first paper screw 16. Through the cooperation of the first paper bottle body 13, the second paper bottle body 14, the paper bottle mouth piece 15, and the first paper screw 16, the plant fiber material can be applied to prepare a bottle with a complex structure, thereby increasing the application scenarios of the plant fiber material, facilitating the preparation of the paper bottle body assembly 10, simplifying the preparation process of the paper bottle body assembly 10, and reducing the preparation cost of the paper bottle body assembly 10. In addition, the paper bottle body assembly 10 of the application comprises the first paper bottle body 13 and the second paper bottle body 14 which are nested inside and outside, so that the paper bottle body assembly 10 has better mechanical strength.

[0061] Please see Figures 4 to 6 In some embodiments, the paper bottle mouth piece 15 comprises a first paper bottle mouth part 151, a second paper bottle mouth part 152, and a third paper bottle mouth part 153 which are connected in sequence and are bent; the first paper bottle mouth part 151 and the third paper bottle mouth part 153 are bent in opposite directions compared with the second paper bottle mouth part 152; the first paper bottle mouth part 151 is used for sleeving the first paper screw 16; an end face of the second paper bottle mouth part 152 facing the first paper bottle mouth part 151 is flush with an end face of the second paper bottle body 14 close to the first paper screw 16; and the third paper bottle mouth part 153 is arranged in the second paper bottle body 14 and connects an inner wall of the second paper bottle body 14.

[0062] It can be understood that the first paper bottle mouth part 151, the second paper bottle mouth part 152, and the third paper bottle mouth part 153 are annular structures, the second paper bottle mouth part 152 is arranged around the outer periphery of the first paper bottle mouth part 151, and the third paper bottle mouth part 153 is arranged around the outer periphery of the second paper bottle mouth part 152. Alternatively, the radial dimension of the third paper bottle mouth part 153 is greater than the radial dimension of the first paper bottle mouth part 151.

[0063] It should be noted that the first paper bottle mouth part 151, the second paper bottle mouth part 152, and the third paper bottle mouth part 153 are an integral structure; in other words, the first paper bottle mouth part 151, the second paper bottle mouth part 152, and the third paper bottle mouth part 153 are different parts of the same component. The first paper bottle mouth part 151, the second paper bottle mouth part 152, and the third paper bottle mouth part 153 are formed in the same process; for example, in the same processes of pulping, adsorption forming, drying and shaping, etc. It can also be understood that there is no splicing interface between the first paper bottle mouth part 151 and the second paper bottle mouth part 152, and between the second paper bottle mouth part 152 and the third paper bottle mouth part 153.

[0064] Optionally, the first paper bottleneck 151 and the first paper screw 16 can be connected by a degradable adhesive.

[0065] Optionally, the third paper bottleneck 153 and the second paper bottle body 14 can be connected by a degradable adhesive.

Through the structural arrangement of the paper bottleneck 15, the paper bottleneck 15 can be well connected with the first paper screw 16 and the second paper bottle body 14, so that the connection between the first paper bottle body 13, the second paper bottle body 14, the paper bottleneck 15 and the first paper screw 16 is more stable; in addition, the end surface of the second paper bottleneck 152 facing the first paper bottleneck 151 is flush with the end surface of the second paper bottle body 14 close to the first paper screw 16, so that the joint between the paper bottleneck 15 and the first paper bottle body 13 and the second paper bottle body 14 cannot be seen from the appearance of the paper bottle body assembly 10, so that the device bottle body assembly has better appearance effect.

[0067] Please refer to Figure 7 In some embodiments, the surface of the third paper bottleneck 153 facing the second paper bottle body 14 is attached and bonded to the inner wall of the second paper bottle body 14, and the line width d1 of the connection part of the third paper bottleneck 153 and the second paper bottle body 14 is in the range of 4mm≤d1≤7mm.

[0068] Specifically, the line width d1 of the connection part of the third paper bottleneck 153 and the second paper bottle body 14 can be, but is not limited to, 4mm, 4.3mm, 4.5mm, 4.8mm, 5mm, 5.3mm, 5.5mm, 5.8mm, 6mm, 6.3mm, 6.5mm, 6.8mm, 7mm, etc.

[0069] In the embodiment, the line width d1 of the third paper bottle mouth part 153 connected with the second paper bottle body 14 is too narrow, which reduces the stability of the connection between the paper bottle mouth part 15 and the second paper bottle body 14. The line width d1 of the third paper bottle mouth part 153 connected with the second paper bottle body 14 is too wide, which increases the assembly difficulty between the paper bottle mouth part 15 and the second paper bottle body 14.

[0070] Please refer to Figure 7 In some embodiments, the line width d2 of the end surface of the second paper bottle mouth part 152 facing the first paper bottle mouth part 151 ranges from 2mm to 5mm.

[0072] In the embodiment, the line width d2 of the end surface of the second paper bottle mouth part 152 facing the first paper bottle mouth part 151 is too narrow, so that after the paper cover assembly 20 is arranged on the paper bottle body assembly 10, the side wall of the paper cover assembly 20 is easy to protrude compared with the side wall of the paper bottle body assembly 10, thereby affecting the appearance effect of the paper bottle 100. The line width d2 of the end surface of the second paper bottle mouth part 152 facing the first paper bottle mouth part 151 is too wide, so that after the paper cover assembly 20 is arranged on the paper bottle body assembly 10, the paper cover assembly 20 cannot shield the joint between the paper bottle mouth part 15 and the second paper bottle body 14, thereby affecting the appearance effect of the paper bottle 100.

[0073] Please refer to Figure 5 In some embodiments, one end of the first paper screw part 16 abuts against the second paper bottle mouth part 152, and the other end of the first paper screw part 16 is flush with the end of the first paper bottle mouth part 151 away from the second paper bottle mouth part 152.

[0074] It can be understood that the opposite ends of the first paper screw part 16 are flush with the opposite ends of the second paper bottle mouth part 15, respectively.

[0075] In the embodiment, one end of the first paper screw 16 abuts against the second paper bottle mouth 152, so that the joint between the first paper screw 16 and the second paper bottle mouth 152 is hardly visible from the appearance of the paper bottle body assembly 10, and the other end of the first paper screw 16 is flush with the end of the first paper bottle mouth 151 away from the second paper bottle mouth 152, so that the joint between the first paper screw 16 and the first paper bottle mouth 151 can be better weakened, and the paper bottle body assembly 10 has a better appearance effect as a whole.
