[0048] Reference Figure 1-10, the plug-in block 3111 is a circular plug-in block 3111 or a cross-shaped plug-in block 3111. Figure 6-10 When the inserting block 3111 is a circular inserting block 3111, the decoration installation groove 141 is a circular decoration installation groove 141. Figure 1-5 When the insertion block 3111 is a cross-shaped insertion block 3111 , the decoration installation groove 141 is a cross-shaped decoration installation groove 141 .

[0049] In this embodiment, the cap body 1 is an elastic cap body 1. Through the above structure, the inner wall of the covering cavity 131 of the elastic cap body 1 can be pressed against the outer wall of the straw opening 21, so that the cap body 1 can be better fixed on the straw opening 21.

[0050] In this embodiment, a mounting base 4 is further included. The mounting base 4 includes a first mounting portion 41 and a second mounting portion 42. The first mounting portion 41 is connected to the second mounting portion 42. The first mounting portion 41 is used to connect to the cup body 5, and the second mounting portion 42 is used to connect to the cap body 1. Through the above structure, since the mounting base 4 includes the first mounting portion 41 and the second mounting portion 42, the first mounting portion 41 is connected to the second mounting portion 42. The first mounting portion 41 is used to connect to the cup body 5, and the second mounting portion 42 is used to connect to the cap body 1, the mounting base 4 can be mounted on the cup body 5 via the first mounting portion 41. When the user needs to use the straw 2, the covering portion 13 of the cap body 1 can be detached from the straw opening 21 of the straw 2, so that the user can drink the beverage in the cup body 5 through the straw 2. The cap body 1 detached from the straw 2 can be placed on the second mounting portion 42, so that the decoration 3 installed on the cap body 1 can continue to decorate and embellish the cup body 5, and it is also convenient for the user to remove and place the cap body 1.

[0051] In this embodiment, the first mounting portion 41 is a first mounting hook. The first mounting hook includes a mounting body portion 411 and a hook portion 412. The mounting body portion 411 is connected to the hook portion 412, and a hanging space 413 is formed between the mounting body portion 411 and the hook portion 412. The hanging space 413 is used to removably hang the mounting base 4 on the side wall of the cup body 5. The first mounting hook also includes an extension portion 414, which is connected to the mounting body portion 411 and located between the extension portion 414 and the hook portion 412. The second mounting portion 42 is protruded from the extension portion 414. Specifically, the mounting body portion 411 and the hook portion 412 are arranged at an acute, right, or obtuse angle; and the mounting body portion 411 and the extension portion 414 are arranged at an acute, right, or obtuse angle. This structure allows the user to attach the mounting base 4 to the cup body 5 via the first mounting hook.

[0052] In this embodiment, the second mounting portion 42 includes a mounting slot 421 that is detachably connected to the first mounting post 15. This structure allows the cap body 1, detached from the straw 2, to be placed on the second mounting portion 42, allowing the decorative object 3 mounted on the cap body 1 to continue decorating and embellishing the cup body 5. Furthermore, the detachable connection between the mounting slot 421 and the first mounting post 15 allows the cap body 1 to be more securely placed on the mounting base 4.

[0053] In this embodiment, the insertion slot 421 has a central insertion hole 4211 and a first insertion groove unit 4212 connected to the central insertion hole 4211. The insertion slot 421 also has a second insertion groove unit 4213 connected to the central insertion hole 4211. The first insertion groove unit 4212 and the second insertion groove unit 4213 are spaced apart from each other around the central insertion hole 4211. Specifically, the insertion slot 421 also has a third insertion groove unit 4214 and a fourth insertion groove unit 4215 connected to the central insertion hole 4211. The first insertion groove unit 4212, the second insertion groove unit 4213, the third insertion groove unit 4214, and the fourth insertion groove unit 4215 are spaced apart from each other around the central insertion hole 4211.
