[0021] Reference Figure 1 、 Figure 2 With Figure 3 , one embodiment of three -dimensional paper cover of the utility model is applicable to cover setting in a cup body 9, and the cup body 9 surrounds and defines a containing space 90 for containing a beverage (not shown in drawing) and opening upward. The three -dimensional paper cover includes a ring wall 1, a top wall 2 and a sealing piece 3.

[0022] The ring wall 1 surrounds a first axis Z and is adapted to connect the cup body 9.

[0023] The top wall 2 comprises a peripheral edge 21 connected to the ring wall 1 and annular, a convex portion 22 extending upwardly from the peripheral edge 21 along the first axis Z, a crease portion 23 formed on the convex portion 22, a fold line 24 connected to the crease portion 23, and a top portion 25 adjacent to the fold line 24. In the present embodiment, the ring wall 1 and the top wall 2 are made of paper material.

[0024] The convex portion 22 surrounds a spout space 220 communicating with the containing space 90, and has a bottom end 221, a top end 222 opposite to the bottom end 221 along the first axis Z, and a drinking opening 20 formed on the top end 222 and fluidly communicating the spout space 220 with the outside. In the present embodiment, the bottom end 221 of the convex portion 22 is spaced apart from the drinking opening 20 along a second axis Y angled to the first axis Z.

[0025] The crease portion 23 extends obliquely from the top end 222 toward the peripheral edge 21, and divides the convex portion 22 into a first extension region 223, and a second extension region 224 extending upwardly from the bottom end 221 toward the top end 222. The drinking opening 20 is adjacent to the peripheral edge 21 along the second axis Y, and is between the first extension region 223 and the second extension region 224.

[0026] The crease portion 23 has two first creases 231, two first ends 231a respectively formed on the first creases 231 and spaced apart along a third axis X, two second ends 231b respectively formed on the first creases 231 opposite to the first ends 231a, and two second creases 232 formed on the first extension region 223. The third axis X is angled to the first axis Z and the second axis Y, and is substantially perpendicular to the first axis Z and the second axis Y.

[0027] The first creases 231 are spaced apart along the third axis X, and the second ends 231b are adjacent to the peripheral edge 21. The drinking opening 20 is between the first ends 231a. The second creases 232 divide the first extension region 223 into a front slope 225 away from the bottom end 221, and two side slopes 226 between the front slope 225 and the second extension region 224.

[0028] The fold line 24 extends along the third axis X and is connected to the second end 231b at two opposite ends of the third axis X. The top wall 2 is divided into the convex portion 22 and the top portion 25 with the fold line 24 as the center. The top portion 25 is a plane, and the bottom end 221 of the convex portion 22 is located at the fold line 24 and is coplanar with the top portion 25.

[0029] The sealing member 3 is tearably connected to the top wall 2 and is used to close the drinking port 20.

[0030] Referring to Figure 3 With Figure 4 In actual use, the user first tears the sealing member 3 to expose the drinking port 20, then slightly tilts the cup 9 to make the beverage (not shown) flow from the containing space 90 to the mouth space 220, and finally flows out of the drinking port 20, thereby achieving the function of drinking from the mouth.

[0031] Since the drinking port 20 is formed at the top end 222, it can better fit the user's mouth to prevent the beverage from leaking through the gap between the drinking port 20 and the user's mouth. In addition, when the user drinks, the gradually tapered extension structure of the convex portion 22 also helps guide the liquid (i.e., the beverage). Compared to a flat or concave drinking port 20, the convex portion 22 of the present embodiment can make the outflow angle of the beverage more natural, reducing the user's head tilt amplitude. Therefore, the present utility model can indeed achieve the effect of improving the use experience.

[0032] In the present embodiment, the first crease 231 and the second crease 232 of the crease portion 23 and the fold line 24 are configured as press lines or fold lines, but in other embodiments, the first crease 231, the second crease 232, and the fold line 24 can also be half-cut scores obtained by a half-cut process. The aforementioned half-cut process refers to cutting a portion of the thickness of the paperboard (i.e., the top wall 2 of the present embodiment) without cutting completely through, so that the paperboard has a structure that can be bent. Compared to press lines or fold lines, the half-cut process can effectively avoid the problem of excessive pressure causing compression of the paperboard or insufficient pressure causing unclear scores, with the advantage of high process yield.

[0033] From the above description, the advantages of the foregoing embodiments can be summarized as follows:

[0034] 1. Since the drinking port 20 is formed at the top end 222 of the convex portion 22, it can better fit the user's mouth to prevent the beverage from leaking through the gap between the drinking port 20 and the user's mouth, providing a good use experience.

[0035] 2. When the user drinks, the special structure design of the tapered extension of the convex part 22 also helps to guide the liquid (i.e. the beverage) to make the outflow angle of the liquid more natural, and reduces the head inclination amplitude of the user.

[0036] The above is only an embodiment of the present application, and cannot limit the scope of the present application. Any simple equivalent changes and modifications made in accordance with the claims and content of the specification are still within the scope of the present application.
