The "one" or "at least one" prefixed to the nouns mentioned in the text does not limit the quantity. According to requirements, it can also be "plural" in number. Such changes in quantity are also within the scope of protection. This is stated first for clarification.

[0044] Please refer to FIGS. 1 to 3, which show a first preferred embodiment of the present application. The paper container 1 of the present application includes a paper layer 10, at least one pattern unit 20, and at least one waterproof and light-transmitting layer 30, 30'.

[0045] The paper layer 10 includes at least one basic pattern area 11; the at least one pattern unit 20 is disposed within the at least one basic pattern area 11. Each pattern unit 20 includes at least one hollow structure 21 and at least one printing unit 22. The at least one hollow structure 21 and the at least one printing unit 22 together form a complete pattern; the at least one waterproof and light-transmitting layer 30, 30' is disposed on at least one side of the paper layer 10 and closes the at least one hollow structure 21. The at least one hollow structure 21 and each waterproof and light-transmitting layer 30, 30' overlap each other in the thickness direction to form at least one viewing window 40.

[0046] Furthermore, each basic pattern area 11 defines a boundary line 2. The boundary line 2 corresponds to the outer contour of one pattern unit 20 and maintains a spacing D3 between the boundary line 2 and the outer contour of one pattern unit 20. The size of the spacing D3 is less than 1.00 cm; preferably, the size of the spacing D3 is less than 0.50 cm.

[0047] The at least one pattern unit 20 (complete pattern) forms a character or an object graphic. In this embodiment, the at least one pattern unit 20 forms the object graphic, which is a bird as shown in the figure, or it can also be a plant, a human figure, an animal figure, other items, or a combination of the above to form a complete graphic, etc. It can also be a symbol, a logo, etc. In addition, the at least one pattern unit can also be a complete and integral design pattern formed by combining characters and patterns, such as a design graphic or pattern of drawing a leaf on the character "wood". In other embodiments, the character can be Chinese characters, Japanese characters, Korean characters, numbers, or other characters. For example, the at least one pattern unit can also be the Chinese character "tea" and the Japanese character "の", but it is not limited thereto.

[0048] The paper container 1 is a cup, and can also be a bowl, a bottle, a lunch box, a beverage box, etc. The paper container 1 can hold liquids and articles.

[0049] Thus, the user can observe the interior of the paper container 1 through the window 40. It is worth noting that only a few hollow structures 21 are required to cooperate with the at least one printing unit 22 to form the complete pattern. The overall structure is strong, providing aesthetics and visually presenting a rich sense of layering and three-dimensionality, thereby fully achieving marketing or other purposes of attracting consumer attention.

[0050] The at least one printing unit 22 (a first printing unit 221) is disposed outside the at least one hollow structure 21. In other embodiments, the at least one printing unit is disposed within the at least one hollow structure, for example, overlapping with the at least one hollow structure or disposed on the at least one waterproof and light-transmissive layer corresponding to the at least one hollow structure.

[0051] The paper container 1 includes a plurality of waterproof and light-transmitting layers 30, 30', which are disposed on opposite sides of the paper layer 10 and respectively seal opposite sides of the hollow structure 21. One of the waterproof and light-transmitting layers 30, 30' is disposed on one side of the at least one printing unit 22. This provides waterproof and light-transmitting properties and prevents the at least one printing unit 22 from falling off.

[0052] Each of the waterproof and light-transmitting layers 30, 30' is a plastic film layer coated on the paper layer 10 to facilitate processing and prevent it from falling off. In other embodiments, each of the waterproof and light-transmitting layers can be laminated, bonded, or sprayed on the paper layer.

[0053] The paper container 1 includes a wall portion 50 and a chamber 60 . The wall portion 50 forms the chamber 60 . The wall portion 50 includes the paper layer 10 and the waterproof and light-transmitting layers 30 , 30 ′.

[0054] Please refer to Figures 4 to 5, which show a second preferred embodiment of the present application, in which the at least one printing unit 22 extends from the inside of the at least one hollow structure 21 to the outside of the at least one hollow structure 21; that is, the at least one printing unit 22 partially overlaps with the at least one hollow structure 21 in the thickness direction, and can also be arranged in the at least one waterproof and light-transmitting layer 30, 30'; in this embodiment, the at least one printing unit 22 (a second printing unit 222) forms a continuous pattern inside and outside the at least one hollow structure 21, such as the wings in Figure 4, so that the at least one printing unit 22 can present a sense of deep and shallow layers and a three-dimensional effect.

[0055] Preferably, the at least one pattern unit 20a includes a plurality of printing units 22, each of which includes a first printing unit 221 and a second printing unit 222. The first printing unit 221 is disposed outside the at least one hollow structure 21, while the second printing unit 222 extends from within the at least one hollow structure 21 to the outside of the at least one hollow structure 21, forming a continuous pattern. The first printing unit 221 and the second printing unit 222 may each be plural. Furthermore, the plurality of first printing units 221 and the plurality of second printing units 222 may be spaced apart from each other. This enhances the three-dimensional visual effect and visual richness. Specifically, the plurality of printing units 22 may have different or identical shapes and colors.

[0056] The first printing unit 221 is disposed between the paper layer 10 and one of the waterproof and light-transmitting layers 30 , 30 ′. The second printing unit 222 is disposed between the two waterproof and light-transmitting layers 30 , 30 ′.

[0057] Please refer to Figures 6 and 7, which show a third preferred embodiment of the present application. The paper layer 10 includes a plurality of basic pattern areas 11a, 11b, including a plurality of pattern units 20a, 20b. The plurality of pattern units 20a, 20b are arranged in the plurality of basic pattern areas 11a, 11b. The plurality of pattern units 20a, 20b are spaced apart from each other and define a first spacing distance D1 therebetween. A minimum distance D2 between adjacent hollow structures 21 of a printing unit 22 is less than the first spacing distance D1, so as to clearly distinguish the independent pattern units 20a, 20b.
