Description

Technical Field

[0001] This invention relates to the structure of a beverage container, particularly a paper bottle container. Prior Technology

[0002] Traditional beverage containers are mostly made of plastic, with polyvinyl chloride (PVC) and polyethylene terephthalate (PET) being the two most commonly used types. While PVC has advantages such as resistance to strong acids, durability, and low cost, it is prone to deformation and decomposition when heated, and it can even produce dioxins when incinerated. Furthermore, it has a low recyclability rate, leading Taiwan's Environmental Protection Administration to ban its use in food packaging starting in 2023. On the other hand, PET has advantages such as high recyclability, non-toxicity, and good hardness and toughness. However, PET is not heat-resistant and is difficult to mold and process, and it also poses potential health risks to humans.

[0003] Therefore, how to develop a beverage container that meets environmental protection requirements, is biodegradable, and does not affect its performance has become a pressing problem in this field. Summary of the Invention

Figure 2 is a structural assembly diagram of the paper bottle container of the present invention. Figure 3 is a partial structural schematic diagram of the paper bottle container of the present invention. Implementation

[0021] The terms "first" and "second" used in this article are only used to distinguish one named object from another object with the same name, and should not be interpreted as implying relative importance or implying the number, specific order, or primary and secondary relationship of the indicated technical features.

[0022] It should be noted that all illustrations in this specification are for illustrative purposes only. For clarity and ease of explanation, the size and scale of the components in the illustrations may be exaggerated or reduced. Generally, the same reference symbols in the illustrations are used to indicate corresponding or similar component features in modified or different embodiments.

[0023] Please refer to Figures 1 and 2. Figure 1 is an exploded view of the paper bottle container of the present invention. Figure 2 is an assembled view of the paper bottle container of the present invention.

[0024] As shown in Figures 1 and 2, the paper bottle container 10 of the present invention includes: a paper bottle body 20, which is made of a first plant fiber through a molding process; a bottle bottom 30, which is disposed at the bottom of the paper bottle body 20 and is made of a second plant fiber through a molding process; a bottle mouth 40, which is located at the upper end of the paper bottle body 20, and the outer wall of the bottle mouth 40 has a smooth surface; and a bottle cap 50, which is made through a molding process and is detachably installed on the bottle mouth 40, and the inner wall of the bottle cap 50 has a surface with a threaded section protruding.

[0025] In addition, the outer surface of the paper bottle body 20 can be designed and processed in a variety of ways, so that its outer surface is not presented in a single shape, texture, color and combination thereof, thereby increasing the visual effect and recognizability, so as to meet the needs of different usage scenarios and consumer groups.

[0026] The molding process can be any of blow molding, compression molding, or injection molding.

[0027] The outer edge of the bottle opening 40 is rounded. When the user uses the paper bottle container 10 to drink beverages, this design can reduce the discomfort when it comes into contact with the lips, thereby improving the user's comfort during the drinking process.

[0028] The first plant fiber can be a plant-based paper product such as sugarcane paper, bamboo paper, or rice straw paper, and the second plant fiber can also be a plant-based paper product such as sugarcane paper, bamboo paper, or rice straw paper, but the present invention is not limited thereto. In a preferred embodiment, the first plant fiber and the second plant fiber are the same sugarcane paper. Since sugarcane is rich in sugar and water, it can be processed into sugar and alcohol products, while the sugarcane bagasse is retained as a residue. The sugarcane bagasse is then used as a raw material to prepare sugarcane paper, which can be used as the material for the paper bottle body 20 and the bottle bottom 30.

[0029] The manufacturing process involves mixing plant pulp with a waterproofing agent, then crushing it evenly using a pulper. The pulp is then screened, diluted, and injected into a molding machine to obtain a shaped pulp. A mold is then used to initially shape the pulp (i.e., the shape of a container). Finally, the pulp is set at high temperature and cooled to obtain a paper bottle container 10.

[0030] As mentioned above, containers made from sugarcane paper are environmentally friendly, durable, and lightweight. Containers made from bamboo paper and rice straw paper also possess similar durability and lightweight properties. Therefore, the paper bottle container 10 of this invention can reduce the use of plastics, and by utilizing the inherent properties of plant-based paper products, the bottle body 20 and bottle bottom 30 possess biodegradability and recyclability, thereby contributing to the protection of the natural environment.

[0031] In one embodiment, the bottle cap 50 is made of metal; in another embodiment, the bottle cap 50 is made of biomaterial. Specifically, in one embodiment, the biomaterial is polylactic acid (PLA); in another embodiment, the biomaterial is polyethylene furanoate (PEF). Furthermore, the bottle cap 50 is made of metal material by compression molding, and the bottle cap 50 is made of biomaterial by injection molding.

[0032] Considering that most bottled containers sold on the market use plastic caps to seal the bottle opening, but each time the plastic cap is opened and closed, friction occurs between the two, causing approximately 500 tiny plastic particles to fall into the liquid. In view of the above, the bottle cap 50 of this invention can be selected from either iron or biomaterials, primarily to reduce the use of plastic and avoid the risk of cancer from ingesting excessive amounts of microplastics.

[0033] On the other hand, the paper bottle container 10 preferably includes a coating 60, which is disposed on the inner or outer surface of the paper bottle body 20. More specifically, the plastic material is melted at high temperature and then uniformly coated onto the outer surface of the paper bottle body 20 by spraying or roller coating. After cooling, it solidifies to form a thin film structure, namely the coating 60. The coating 60 is made of a biomaterial, such as polylactic acid or other biomaterials, but is not limited thereto.

[0034] In addition, the coating 60 can extend the storage time of the liquid in the paper bottle container 10. During this period, the paper bottle container 10 will maintain its own structure and shape and will not soften or deform due to prolonged contact with the liquid, making it suitable for long-term liquid storage. Furthermore, since the coating 60 has high temperature resistance, it helps to reduce the heat felt by the user when holding the paper bottle container 10, thereby improving the user's hand handling convenience and drinking comfort.

[0035] Please refer to Figure 3, which is a partial structural schematic diagram of the paper bottle container of the present invention.

[0036] As shown in Figure 3, the diameter of the bottle opening 40 gradually widens from top to bottom to form an inclined plane 70. The inclined plane 70 has an angle relative to the axis L perpendicular to the bottle opening plane 80. , among which angle It is between 1° and 20°.

[0037] In existing technologies, a spiral pattern between the bottle opening and the cap is used for sealing, preventing leakage of the liquid inside. However, the bottle opening 40 of this invention has a smooth surface, making it impossible to use existing technologies for sealing. Therefore, this invention utilizes an angled... The inclined surface 70, when the cap 50 is screwed down or pressed onto the bottle mouth 40, makes the cap 50 and the bottle mouth 40 increasingly tight during the installation process, thereby effectively improving the sealing performance and preventing the joint from loosening and causing leakage, thus achieving the function of a stable seal.

[0038] In summary, the material used in the paper bottle container 10 of this invention is biodegradable and has a high recyclability rate. It can decompose into harmless substances in the natural environment and further reduce resource waste and carbon emissions. Therefore, this invention can reduce the use of plastics, benefit environmental protection, and promote sustainable development.
