You don't need to open the lid, just open the big hole in the lid.
The Rejuveno coffee lid has two openings, and the larger hole is for drinking. Coffee lids tend to have two holes in them, where the larger one is for direct drinking and the smaller one is for ventilation. It would be very inconvenient to drink without the smaller hole, so you just have to look for the one that's a little on the larger side near the edge of the cup.

There are four main types of Rejuvenate Coffee cup lids: peeling, pinching, pouting and piercing. Peeling the lid of the cup is to tear off a small piece of film from the notched position and drink the coffee. Squeezing is similar to peeling, except that you need to use the pressure of your thumb and forefinger to snap the lid when you open it, rather than tearing it off completely.
Punching involves pressing a raised button. When the button is pressed, a crack appears, which keeps the lid intact and prevents it from accidentally tearing when you pull on it. The "sip" style is to drink coffee directly from the raised mouth on the lid, where the lips don't touch the surface of the cup and it looks like a sip, hence the name "sip".
Most people drink a cup of coffee in the morning. Some cups can't be closed again after opening, and spill out with the shaking of feet, or even splash on the body. Therefore, the lid is constantly updated and improved, and different forms of lids are beginning to appear, not only to keep the lid intact and prevent splashing, but also to facilitate people to drink coffee at any time.
