Aspects and embodiments injection of supplements into drinks are described. In one embodiment, a cap includes a top of the cap having a button. A container is sealed using a sealing layer between the container and the top. A pushing element is in connection with a bottom surface of the button and further in connection with a top surface of the sealing layer.
