[0038] Hereinafter, with reference to the attached drawings, a cup lid according to the present invention and a paper cup using the lid will be described in detail. The present invention is not limited or restricted by these examples. Furthermore, in describing the present invention, detailed descriptions of known functions or components may be omitted to clarify the gist of the present invention.

[0039]

[0040] From now on, a paper cup according to one embodiment of the present invention will be described.

[0041] A paper cup according to one embodiment of the present invention may include a cup body (20) and a cover module (10) as shown in FIGS. 1 to 5.

[0042] The cup body (20) has a drinking space (21) formed inside, and an upper opening that connects the upper part of the drinking space (21) to the outside. In one embodiment of the present invention, a cup rim (22) may be provided on the upper part of the cup body (20).

[0043] The cover module (10) is coupled to the cup body (20) so that the upper opening of the cup body (20) can be opened and closed. The cover module (10) may include a cup lid according to one embodiment of the present invention.

[0044] A cup lid according to one embodiment of the present invention may include a lid body (11), an opening cover (12), a closing cover (13), and an opening bracket (14).

[0045] The cover body (11) is joined to the inner surface (23) of the cup body (20). The cover body (11) can be bent into a tubular shape and joined to the inner surface of the cup body (20) using various known forms such as ultrasonic welding.

[0046] The cover body (11) can exhibit a tubular shape by using various known methods such as ultrasonic welding via a joint (111). The joint (111) may be omitted.

[0047] The opening cover (12) is formed to extend from the cover body (11) so that it can be folded from the cover body (11). Although not shown, a drinking opening (100) may be formed through the opening cover (12).

[0048] The closing cover (13) is formed to extend from the cover body (11) so as to be foldable, and is placed on one or both sides of the opening cover (12). One or more closing covers (13) may be formed to extend from the cover body (11).

[0049] The opening bracket (14) can be separated from a part of the cover body (11) and a part of the opening cover (12).

[0050] Then, when the opening cover (12) is folded based on the cover body (11), a part of the opening bracket (14) is separated from the cover body (11) and the opening cover (12). Then, a drinking opening (100) is opened between the mutually separated cover body (11), the opening cover (12), and the opening bracket (14).

[0051] In more detail, as illustrated in FIG. 3, a cover folding part (112) that has an arc shape in the unfolded state of the cup lid is provided at the boundary between the cover body (11) and the opening cover (12). In addition, as illustrated in FIG. 3, a cover folding part (112) that has an arc shape in the unfolded state of the cup lid is also provided at the boundary between the cover body (11) and the closing cover (13). It is preferable that this cover folding part (112) have an arc shape by the trace of the cutting cross-section formed in the cover body (11) when the cover body (11) having a tubular shape is cut obliquely via the connecting part (111). Accordingly, when viewed from the side of the cover body (11) having a tubular shape as illustrated in FIG. 1 or FIG. 2, the cover folding part (112) may overlap to form a line segment that slopes upward from the side of the cover body (11) toward the upper end of the cover body (11).

[0052] The cover body (11) and the opening cover (12) may be provided with a pair of cutting portions (15) that are spaced apart from each other and intersect with the cover folding portion (112) so that a part of the opening bracket (14) can be separated from the cover body (11), and that are spaced apart from each other and intersect with the cover folding portion (112) so that a part of the opening bracket (14) can be separated from the opening cover (12). The pair of cutting portions (15) are provided on each side of the opening bracket (14) as illustrated in Fig. 3 to enable separation from the cover body (11) and the opening cover (12).

[0053] At one end of a pair of cutting portions (15), an opening folding portion (161) is provided, which forms a boundary between the opening cover (12) and the opening bracket (14), and by which the opening bracket (14) can be folded based on the opening cover (12). Accordingly, the opening folding portion (161) is spaced apart from the upper side of the cover body (11) as illustrated in FIG. 3, and connects one end of the pair of cutting portions (15). In addition, at the other end of the pair of cutting portions (15), a main body folding portion (162) is provided, which forms a boundary between the cover body (11) and the opening bracket (14), and by which the opening bracket (14) can be folded based on the cover body (11). Accordingly, the main body folding portion (162) is spaced apart from the lower side of the opening cover (12) and connects the other end of the pair of cutting portions (15).

[0054] In addition, a pair of cutting parts (15) are connected between the opening folding part (161) and the main body folding part (162) to partition the opening bracket (14), and a bracket folding part (163) in which the opening bracket (14) can be folded is provided. The bracket folding part (163) is spaced apart from the opening folding part (161) and the main body folding part (162) and crosses the opening bracket (14). The opening folding part (161), the main body folding part (162), and the bracket folding part (163) are arranged parallel to each other to implement the cutting folding part (16).

[0055] For example, when the bracket folding part (163) is arranged to be biased toward the main body folding part (162) with respect to the cover folding part (112), when the opening cover (12) is folded with respect to the main body (11), the bracket folding part (163) inevitably goes downward as shown in FIG. 4.

[0056] As another example, when the bracket folding part (163) is arranged to be biased toward the opening folding part (161) with respect to the cover folding part (112), when the opening cover (12) is folded with respect to the cover body (11), the bracket folding part (163) may rise upward or fall downward.

[0057] Looking at a paper cup according to one embodiment of the present invention, the cover body (11) is formed into a tubular shape via a connecting portion (111) in various known forms, and as illustrated in Fig. 1, the cover body (11) is connected to the inner surface (23) of the cup body (20). As illustrated in Fig. 5, the paper cup according to one embodiment of the present invention can be easily stored and transported by being mutually stacked and connected.

[0058] Next, by folding the opening cover (12) and the closing cover (13) based on the cover body (11), the upper opening of the cup body (20) can be closed. At this time, since the cutting portion (15) opens, a part of the opening bracket (14) is separated from the cover body (11) and the opening cover (12), and as shown in FIG. 4, the opening bracket (14) is folded based on the cover body (11), the opening bracket (14) is folded based on the opening cover (12), and the opening bracket (14) is folded, so that a drinking opening (100) can be easily formed between the cover body (11), the opening cover (12), and the opening bracket (14).

[0059]

[0060] From now on, a paper cup according to another embodiment of the present invention will be described.

[0062] The cup body (20) has a drinking space (21) formed therein, and an upper opening that connects the upper part of the drinking space (21) to the outside. The cover module (10) is formed to extend to the upper part of the cup body (20) so that the upper opening can be opened and closed. The cover module (10) may include a cup lid according to one embodiment of the present invention.

[0063] In the cover module (10) according to another embodiment of the present invention, the same configuration as the cover module (10) according to one embodiment of the present invention is given the same drawing reference numerals and a description thereof is omitted. However, in the other embodiment of the present invention, the cover body (11) is formed to extend from the upper end of the cup body (20) as illustrated in FIG. 6. In addition, since the cover module (10) is formed to extend from the cup body (20), the cup rim (22) is omitted from the upper end of the cup body (20).

[0064]

[0065] According to the cup lid described above and the paper cup using the same, both the cover module (10) and the cup body (20) are formed of paper material, and the upper opening of the cup body (20) can be easily opened and closed depending on whether the cover module (10) is folded, and when the cover module (10) is folded, the drinking opening (100) in the cover module (10) is opened to facilitate the discharge of the fluid contained in the cup body (20).

[0066] In addition, since the opening cover (12) and the plurality of closing covers (13) can be folded based on the cover body (11) through the detailed connection relationship of the cover module (10), the upper opening of the cup body (20) can be easily opened and closed. In addition, even if the opening cover (12) and the plurality of closing covers (13) close the upper opening of the cup body (20), the drinking opening (100) in the cover module (10) is opened, so that the fluid contained in the cup body (20) can be smoothly discharged.

[0067] In addition, the opening cover (12) and multiple closing covers (13) can be folded smoothly based on the cover body (11) through the joint relationship of the cover folding part (112).

[0068] In addition, the flatness of the opening cover (12) and the plurality of closing covers (13) that are folded based on the cover body (11) can be adjusted through the joint relationship of the cover folding part (112).

[0069] In addition, through the joint relationship of the cutting portion (15), a part of the opening bracket (14) can be stably separated from the cover body (11) and the opening cover (12) depending on whether the opening cover (12) is folded based on the cover body (11), and when the upper opening of the cup body (20) is closed, the drinking opening (100) can be easily opened.

[0070] In addition, through the connection between the opening folding part (161) and the main body folding part (162), it is possible to clearly determine whether the opening bracket (14) is folded based on the cover body (11) and the opening cover by linking it with whether the opening cover (12) is folded based on the cover body (11), and when the upper opening of the cup body (20) is closed, the drinking opening (100) can be easily opened.

[0071] In addition, through the joint relationship of the bracket folding part (163), the folding of the opening cover (12) based on the cover body (11) and the folding of the opening bracket (14) based on the cover body (11) and the opening cover are linked to clearly determine whether the opening bracket (14) is folded, and when the upper opening of the cup body (20) is closed, the opening of the drinking opening (100) can be easily performed.

[0072] In addition, through the first coupling relationship between the cup body (20) and the cover module (10), the cover module (10) can be easily coupled to the general cup body (20), and the upper opening of the general cup body (20) can be easily opened and closed.

[0073] Additionally, the cup body (20) can be reinforced through the bonding relationship of the cup rim (22).

[0074] In addition, a new type of paper cup can be implemented through the second bonding relationship between the cup body (20) and the cover module (10), and the upper opening of the new type of cup body (20) can be easily opened and closed.

[0075] In addition, the paper cup according to one embodiment of the present invention maintains the shape of the cup smoothly through the cup rim (22), and since it uses an existing cup body (20) rather than a new one, only equipment for combining the cover module (10) to the existing equipment can be added, reducing production costs, and the material of the cup body (20) can be applied as is to the cover module (10).

[0076] Furthermore, a paper cup according to another embodiment of the present invention simplifies the production process and enables the production of paper cups at low cost. Furthermore, compared to one embodiment of the present invention, the number of layers can be increased based on the same height, thereby reducing distribution costs.

[0077]
