Description

Cup lid

The present invention relates to a cup lid, and more particularly to a disposable lid for covering a cup.

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 body, a slight force holding may cause the cup body and its buckle lip to be slightly deformed. At this time, the convex portion 1 is easy. 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 with the manufacturer, so the cups are also common. 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 A primary object of the present invention is to provide a cup cover that can be securely capped to a cup.

Another main object of the present invention is to provide a cup cover that is less susceptible to the thickness of the button by the thickness of the button.

To achieve the above object, the present invention provides a cup cover including a top portion, a ring side panel and at least one snap portion.

The ring side panel extends downwardly from the periphery of the top. The buckle portion is disposed on the ring side plate and is located in the ring side plate. The buckle portion includes a body having a bottom side and a top side. The bottom side is disposed on the ring side plate, and the top side extends upward. The top side is separated from the side panel of the ring such that a compression space is formed between the sheet body and the side panel of the ring, and the sheet body and the side panel of the ring have elasticity so that the sheet body can be elastically compressed toward the compression space.

Thereby, the cup cover provided by the invention can be covered on the cup body having the buckle lip, and when the cup body is closed, the sheet body can be elastically compressed to the compression space, and the top cover is attached to the buckle lip, and then the sheet body That is, the elastic reset causes the buckle lip to be clamped between the sheet body and the top portion, so that the cup lid of the present invention can be firmly snap-fitted with the cup body, and even if the thickness of the cup body buckle lip is slightly changed, it is still not easily The lid is separated for excellent use.

The following is a description of the possible embodiments of the present invention, and 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 a cup body 10. The cup body 10 has a body 11 and a buckle lip 12, and the cup body 11 is cylindrically formed. An upper opening, the fastening lip 12 surrounds the upper opening, wherein the cup 10 may be a cup of paper cup, plastic cup or other material. In this embodiment, the lid includes a top portion 20, a ring side panel 30 and six snap portions.

The top portion 20 is directly attached to the buckle lip 12 and covers the opening above the cup body 10. The top portion 20 may be provided with a groove, a protrusion or an opening for the straw to be inserted, or directly for the user. Drinking the beverage contained in the cup, preferably, the top portion 20 is formed with an annular abutment wall 21 that extends downwardly to abut against 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, and an annular receiving groove is formed between the abutting wall 21 and the ring side plate 30. The buckle lip 12 is received 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 arranged annularly in the ring side panel. Each of the latching portions includes a single 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 end is directly connected to the ring side plate 30, the top side 412 extends upward, and the top side 412 is separated from the ring side plate 30, so that a compression space 43 is formed between the sheet body 41 and the ring side plate 30. There is elasticity between the 41 and the ring side panel 30, so that the sheet body 41 can be elastically compressed toward the compression space 43, wherein preferably, the top side 412 extends between the abutting wall 21 and the ring side panel 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. In this embodiment, the cup cover has a corresponding number of six notches 31 and six snap portions. However, it is also unnecessary to change the notch 31 and the buckle portion to one or the other.

Thereby, referring to FIG. 7 to FIG. 12, the cup cover provided by the present invention can be covered with the cup body. As shown in FIG. 7, when the cup lid and the cup are still separated from each other, the sheet body 41 is in its initial position and is not compressed toward the compression space 43. Next, when the cup is brought close to the cup and is intended to be placed on the cup, the sheet 41 presses the buckled lip 12 to be compressed toward 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 button lip 12 and the cup body 11. When the lid is lifted up, the sheet is lifted. The body 41 can be abutted against the buckle lip 12, and the cup body 10 can be prevented from being arbitrarily separated from the cup cover. Even if the cup body 10 is slightly deformed by being squeezed, the cup body 10 does not easily fall off from the cup lid.

In addition, when the cup cover of the present invention has a plurality of fastening portions, the sheet bodies 41 of the fastening portions can have two or more different lengths from each other, more specifically, the sheet body 41 The length refers to the distance from the top side 412 to the bottom side 411. Some of the sheets 41 have one length and another portion has another length. Preferably, the sheets of different lengths can be cross-mixed and arranged. Thereby, when the present invention is applied to the cup body 10 having a relatively thick thickness of the buckle lip 12, the shorter length of the sheet body can be used to abut the top lip 12, and when the present invention is applied to the cup having a thin thickness of the buckle lip 12 In the case of the body 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, the top side 412 of the sheet can be used to abut the button lip 12 of the cup body, and the ring side plate 30 can be clamped against the abutting wall 21 by the ring side plate 30. On both sides of the buckle lip 12, even if the thickness or diameter of the buckle lip 12 is slightly changed, 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 closely covered with similar dimensions. 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 the effect of making remarkable progress, conforms to the relevant provisions of the Patent Law, and files a patent application according to law, so that the Office can approve the patent as soon as possible.
