Description of the Invention: [Technical Field of the Invention] The present invention relates to a cup cover, and more particularly to a disposable cup cover for covering a cup. [Prior Art] Please refer to Figure 1. In order to buckle the top edge of the cup, the conventional cup cover is generally provided with a convex portion 1 at the buckle portion thereof, and the convex portion 1 is provided to abut the outer edge of the lower lip of the cup body to achieve a fixing effect. . However, the conventional cup lid is often criticized in use. When the user holds the cup, a slight force holding may cause the cup body and its buckle lip to be slightly deformed. Self-slip lip slip is one of its defects; in addition, the cups made by different manufacturers, even if the cups are the same size, the thickness and diameter of the buckles will vary depending on the manufacturer. When the cover is fastened to the cup with a thin lip, the buckle effect is weak, which also causes the lid to fall off easily. In view of the insufficient ability of the conventional cup lid to be fixed to the cup body, how to further improve the structure of the cup lid is self-directed in the direction of the industry. SUMMARY OF THE INVENTION The main object of the present invention is to provide a cup that can be used on a cup to another cup of the present invention. The main purpose is to provide a kind of non-impact lip thickness effect, including a top, in order to achieve the above purpose, the present invention provides a cup cover 201228903 one ring side plate and at least one buckle portion. The ring side panel extends downwardly from the periphery of the top. The buckle portion is disposed on the side panel and located in the side panel of the ring, the buckle portion includes a body, the body has a bottom side and a front side. The bottom side is disposed on the side panel of the ring, and the side of the flange extends upward. Separating from the side plate of the ring, a pressure is formed between the sheet and the side plate of the ring. The piece has elasticity between the piece and the side plate of the ring, so that the piece can be elastically compressed toward the pressing space. Therefore, the cup cover provided by the invention can be attached to the cup body having the buckle lip, and when the cup body is covered, the sheet body can be elastically compressed and contracted, and the top cover is attached to the buckle lip. Then, the sheet body is elastically reset, so that the buckle lip is clamped between the sheet body and the top portion, so that the cup lid of the invention can be firmly snap-fitted with the cup body, even if the thickness of the cup body buckle lip slightly changes, still not It is easily separated from the lid and has a recording effect. [Embodiment] The following description of the possible embodiments of the present invention is not intended to limit the scope of the invention as claimed. Referring to FIG. 2 to FIG. 5, the present invention provides a cup cover for covering the cup body 10. The cup body 10 has a cup of 彡u and a button lip 12, and the cup body 11 is formed into a tube. The shape has an upper opening σ, and the fastening lip 12 surrounds the upper opening 'where the cup 1G may be a cup of paper cup, plastic cup or other material. In the present embodiment, the lid includes a top portion 2G, a ring side panel 3〇 and six snap portions. 201228903 The top 20 series is attached directly to the buckle lip 12 and is placed over the opening 1 of the cup 1 'where the top 20 may be provided with a groove, a projection or an opening for the straw to be inserted or used The beverage is contained directly in the cup. Preferably, the top portion 20 defines an annular abutment wall 21 that extends downwardly to abut the inner edge of the buckle lip 12. Referring to FIG. 6, in another embodiment of the present invention, the top portion 20 can also be directly bent to form the abutting wall 21. The ring side plate 30 extends downward from the periphery of the top portion 20 such that the abutting wall 21 is located in the ring side plate 30. An annular receiving groove is formed between the abutting wall 21 and the ring side plate 3'. The buckle lip 12 is accommodated in the receiving groove. The ring side plate 30 can be formed with six notches 31 which can extend to the bottom edge of the ring side plate 30. The latching portions are disposed on the ring side panel 30 and are equally spaced and annularly arranged in the loop side panel. Each of the latching portions includes a body 41 and may further include two connecting tabs 42. The sheet body 41 has a bottom side 411 and a top side 412. The bottom side 411 is disposed on the ring side plate 30'. More specifically, the position of the buckle portion corresponds to the notch 31, and the bottom side 411 The two ends are directly connected to the ring side plate 3 , the top side 412 extends upward, and the top side 412 is separated from the ring side plate 3 , so that a compression space 43 is formed between the piece 41 and the ring side plate 30 . The sheet 41 has elasticity between the ring side plate 30 and the ring side plate 30 so that the sheet body 41 can be elastically compressed toward the compression space 43. Preferably, the top side 412 extends to the abutting wall 21 and the ring side plate. Between 30. The two connecting pieces 42 are respectively connected to the two ends ' of the bottom side 411 of the sheet body and are respectively connected to the ring side plate 30, thereby improving the structural strength between the sheet body 41 and the ring side plate 30 201228903. In the present embodiment, the cup cover has a corresponding number of six notches 31 and six snap portions. However, it is not necessary to change the notch 31 and the buckle portion to one or the other. Thereby, referring to Figures 7 to 12, the lid provided by the present invention can be covered with a cup. As shown in Fig. 7, when the cup lid and the cup are still separated from each other, the sheet 41 is in its initial position and is not compressed toward the compression space 43. Next, when the lid is brought close to the cup and is intended to be placed on the cup, the sheet 41 presses the buckled lip 12 to compress the compression space 43, as shown in Figs. Subsequently, as shown in FIG. 11 and FIG. 12, when the buckle lip 12 moves into the accommodating groove, the buckle lip 12 will pass over the top side 412 of the sheet body, and the sheet body 41 is then elastically reset to its initial position, so that the buckle lip 12 is The clip is abutted between the sheet body 41 and the top portion 20, and the sheet body 41 can be engaged with the groove 13 formed between the buckle lip 12 and the cup body U. When the lid is lifted up, the The body 41 can be placed against the buckle lip 12, and the cup body 1〇/, the cup cover can be prevented from being detached, and the cup body 10 is slightly deformed even if it is squeezed, and the cup body still does not easily cover the cup cover. Fall off. In addition, when the cup cover of the present invention has a plurality of fastening portions, the sheet bodies 4 of the buckle type can have two or more different lengths, and more specifically, the sheet body is Μ The length refers to the distance from the top side 412 to the bottom mu, and some of the sheets 41 have one length and another portion has another length. Preferably, the sheets of different lengths can be mixed and mixed. Therefore, when the present invention is applied to the cup body 1A having a relatively thick thickness of the buckle lip 12, the sheet body having a longer length can be used to abut the top lip 12'. When the cover of the present invention is thinner than the thickness of the buckle lip 12, 201228903 When the cup is 10, the longer length of the sheet can be used to abut the top lip 12, so that the present invention can be more closely covered by a plurality of cups. In the above, when the lid of the present invention is placed on the cup body, the top side 412 of the sheet body can be used to abut the button lip 12 of the cup body, and the ring side panel 30 can be clamped to the sin wall 21 by the ring side panel 30. The sides of the buckle lip 12 are slightly different in thickness or diameter of the buckle lip 12, and the cup cover of the present invention can still be tightly engaged with the buckle lip. In other words, the present invention can be applied and tightly closed to the same size and specifications. Some micro-gap cups do not significantly affect the bonding strength due to the thickness of the lip or the tolerance of the diameter. It is obvious that the invention has greatly improved the long-standing problems of the conventional cup cover, and can satisfy the industry and consumers. Demand. It can be seen from the above that the present invention not only has a novel and practical structure, but also has a remarkable improvement effect, and conforms to the relevant provisions of the patent law. It is necessary to file a patent application according to law, and the SIPO is required to grant a patent as soon as possible.
