[0021] The present utility model will be further described below in conjunction with the drawings:

[0022] The directions described in the utility model specification, such as "upper", "lower", "left", "right", "front", "rear", etc., are all based on the directions of the drawings and are for the purpose of facilitating the description of the relationships between various components, and do not indicate the only or absolute positional relationships between various components. It is only one implementation mode for realizing the utility model and is not a limitation on its implementation mode.

[0023] This embodiment provides a plastic-free and environmentally friendly storage bottle, as Figures 1 to 4As shown, it includes a bottle body 10 and a bottle cap 3 made by paper plastic technology, wherein at least two arc-shaped outer ring pieces 4 are connected to the outer side wall of the top of the bottle body 10, and the outer ring pieces 4 are provided with raised external threads 41, and the inner side wall of the bottle cap 3 is connected to an inner ring piece 5 that matches the shape of the outer ring piece 4 and is correspondingly arranged, and the inner ring piece 5 is provided with an internal thread 51 that matches the shape of the external thread 41 and enables the bottle cap 3 to be screwed on the bottle body 10.

[0024] Preferably, the bottle body 10 is a split structure, and the bottle body 10 is composed of a bottom barrel 1 and a top barrel 2 connected to the top of the bottom barrel 1. In this embodiment, the bottom barrel 1, the top barrel 2, the bottle cap 3, the outer ring piece 4, and the inner ring piece 5 are all made of an integrated structure by a paper-molding process, wherein the paper-molding process can refer to the patent number CN202211190635.3, and the name is a pulp molding product preparation process. The paper-molding process is called "three-dimensional papermaking technology", which is different from papermaking in that it mainly uses pulp as raw material. Its production process: 1) The raw material is crushed in a pulper and soaked in a pulp pool, and a special adhesion promoter is added according to the situation. 2) Then pick it up in a special mesh mold with a filter and squeeze it. This link can squeeze out some water and make the pulp into a rough shape. 3) Then the shape is transported to the final mold for continued squeezing, and it is continuously heated during this process. Due to the plasticity of the paper fiber, it can finally be made into paper plastic. 4) Finally, die-cut and trim. However, the two extrusion steps mentioned above require the use of molds, and there are requirements for the demoulding angle after the mold is formed. The reason why each paper-molding has a demoulding angle is that the paper-molding process technology requires that it is impossible to make a one-piece bottle body or bottle cap simply from the paper-molding aspect. Therefore, a split structure is adopted in this embodiment. The bottom barrel 1, top barrel 2, bottle cap 3, outer ring piece 4, and inner ring piece 5 made by the above process are all one-piece overall structures, and the shape of each component is made more stable through the die-casting process. The related components are then connected and fixed by bonding, which is more solid and full, and has better stiffness. In this way, the specific shape of the chewing gum bottle and the bottle cap can be made by paper molding, and it has high hardness and good precision, which solves the problem of serious pollution caused by the inability to degrade the materials of traditional chewing gum bottles, and improves the environmental protection attributes of the product.

[0025] like Figure 3 and Figure 4 As shown, the top tube 2 is provided with a bottle mouth 21 with a smaller diameter, and the outer ring piece 4 is connected to the outer side wall of the bottle mouth 21. The outer ring piece 4 is connected to the outer side wall of the bottle mouth 21 by bonding, and the inner ring piece 5 is connected to the inner side wall of the bottle cap 3 by bonding. Preferably, the outer ring piece 4 and the inner ring piece 5 are respectively provided with three pieces, and through this setting, independent thread strips are respectively provided, so as to better control the strength and quantity of the buckle and improve the process operability.

[0026] To facilitate the splicing of the bottom barrel 1 and the top barrel 2 to form the bottle body 1, as Figure 4 shown, a plug-in sleeve portion 11 for inserting into the bottom opening of the top barrel 2 is provided at the top of the bottom barrel 1, and the bottom of the top barrel 2 is sleeved on the plug-in sleeve portion 11.

[0027] Preferably, the plug-in sleeve portion 11 and the top barrel 2 are connected together by an adhesive method.

[0028] To facilitate screwing the bottle cap 3, a plurality of vertically arranged anti-slip stripes 31 are provided on the circumferential cylindrical surface of the bottle cap 3.

[0029] The above are only the embodiments of the present invention, and common knowledge such as the specific structures and characteristics known in the solution is not described in detail here.
