BACKGROUND OF THE INVENTION

[0002] US Patent No. 4,262,815 discloses a conical opening with a lid that opens at the top of the can. This makes opening the lid difficult and the flow is unstable when pouring. In addition, the height of the conical shape at the designated location makes it difficult to stack up during transportation.

[0003] US Patent No. 9,315,290 discloses a method that helps stabilize the flow of fluid by creating at least two openings in the can lid. Creation of a second opening can allow air to enter the can via this second opening while fluid leaves the can via the first opening, creating a smoother, more even flow of fluid but still inconvenient for users to drink directly by mouth. In particular, users are very vulnerable to the fluid flowing through the two edges of the lips when contacting the first opening, especially for first-time users.

[0004] Other inventions regard to a can lid opening that do not solve the problem of the difficulty of opening the lid by pulling the tab, users may be injured nails when trying to pull the tab when inserting fingers into the designated space to open the lid. Although there are many methods to overcome this situation such as US patent No. 4,182,460 with a circular hollow in the middle of the can create space for fingers to pull the tab , or US patent No.7, 617,945, Euro patent No. EP1919786 has a small indentation at the beginning of the opening tab to create space for putting nails into the lid to lift up the tab or US public application No. US20090200306 discloses the rotatable pull tab that can extends beyond the perimeter of the lid for opening the lid or by changing the shape of the opening tab for easy pulling like the Euro patent No. EP2750981 by creating a wing shape for the opening tab; these inventions have not completely solved the above problems. SUMMARY OF THE INVENTION

[0005] Accordingly, an object of the present invention is to provide can lid that makes direct oral drinking more convenient, easier opening, protects fingernails when opening and helps to stabilize, accelerate flow of fluid (when pouring), comprising:
