[0030] Example:

[0031] like Figure 1-5As shown, the present embodiment proposes a waterproof, oil-proof, plastic-free, biodegradable film-coated paper cup, comprising a paper cup body 1, wherein the paper cup body 1 comprises a cup body 2 and an annular protrusion 3. Through the provided annular protrusion 3, when a person takes the paper cup body 1, he or she holds the cup body 2 with the palm of his or her hand, so that the lower surface of the annular protrusion 3 contacts the hand. The outer surface of the paper cup body 1 is coated with a bio-based material coating 4. The bio-based material coating 4 itself is biodegradable and has good film-forming properties and anti-slip effects. It can form a uniform film with appropriate friction on the outer surface of the paper cup body 1, which has a good anti-slip effect, thereby reducing The possibility of the paper cup body 1 slipping off the hand is reduced because the lower surface of the annular protrusion 3 is an annular inclined surface, which can better fit the hand and will not cause discomfort. A first cup ring 5 is provided on the top of the cup body 2, and a cup cover 6 is provided on the top of the first cup ring 5. A connecting tube 7 is fixedly connected to the top of the cup cover 6. The inner surface of the paper cup body 1 and the inner surface of the cup cover 6 are both coated with a water-based polymer coating 8. The water-based polymer coating 8 is provided, so that the paper cup body 1 and the cup cover 6 have good waterproof and oil-proof effects, and can be naturally degraded within a certain period of time after being discarded, with less impact on the environment.

[0032] like Figure 4 As shown, a second cup ring 9 that matches the first cup ring 5 is fixedly connected to the inner wall of the cup cover 6 , and the second cup ring 9 is in contact with the first cup ring 5 .

[0033] like Figure 1 and Figure 5 As shown, a plastic tube plug 10 is provided in the connecting tube 7, and a plastic connector 11 is fixedly connected to the top of the plastic tube plug 10. The plastic tube plug 10 can prevent dust in the external air from entering the cup body 2 and contacting the beverage.

[0034] like Figure 3 As shown, the cup body 2 and the annular protrusion 3 are integrally formed, the lower surface of the annular protrusion 3 is an annular inclined surface, and the first cup ring 5 and the cup body 2 are integrally formed.

[0035] like Figure 1 As shown, the inner top wall of the cup cover 6 fits with the first cup ring 5. The cup cover 6 is removed from the cup body 2, so that the second cup ring 9 is out of contact with the first cup ring 5, and the beverage inside can be drunk directly through the cup body 2.

[0036] like Figure 1 and Figure 5 As shown, the plastic tube plug 10 is adapted to the connecting tube 7 . After the plastic tube plug 10 is taken out from the connecting tube 7 via the plastic connector 11 , the beverage in the cup body 2 can be drunk through the connecting tube 7 .

[0037] Specifically, when the waterproof, oil-proof, plastic-free and biodegradable film coated paper cup is used: through the provided annular protrusion 3, when a person takes the paper cup body 1, he or she holds the cup body 2 with the palm of his or her hand, so that the lower surface of the annular protrusion 3 contacts the hand. The bio-based material coating 4 itself is biodegradable and has good film-forming and anti-slip effects. It can form a uniform film with appropriate friction on the outer surface of the paper cup body 1, which has a good anti-slip effect, thereby reducing the possibility of the paper cup body 1 slipping from the hand. Since the lower surface of the annular protrusion 3 is an annular inclined surface, it can better fit the hand without causing discomfort. Through the plastic connector 1 After the plastic tube plug 10 is removed from the connecting tube 7, the beverage in the cup body 2 can be drunk through the connecting tube 7. At the same time, the cup cover 6 can be removed from the cup body 2, so that the second cup ring 9 is separated from the first cup ring 5, and the beverage inside can be drunk directly through the cup body 2. When the plastic tube plug 10 is placed in the connecting tube 7 through the plastic connector 11, dust in the external air can be prevented from entering the cup body 2 and coming into contact with the beverage. The water-based polymer coating 8 is provided, so that the paper cup body 1 and the cup cover 6 have good waterproof and oil-proof effects. After being discarded, they can naturally degrade within a certain period of time, with little impact on the environment.

[0038] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
