Liquid product packaging caps with opening plugs are disclosed. The proposed caps comprise dispensing glands and protection meshes attached to the liquid product packaging caps. In examples, when opening, the opening plugs do not touch the liquid content and fold over the liquid product packaging caps, rather than inside them, while at the same time sharp circumferential edge guards prevent users from touching the sharp circumferential edges of the metal plugs. The dispensing glands are released and prevent the liquid from touching potentially contaminated caps of the liquid product packaging which may have been in contact with polluting and contaminating agents. Protection meshes are fitted or secured to dispensing glands which close the packaging holes after they are opened. The protection meshes, apart from the gaps also prevent insects or objects from entering, have pre-selected pre-cut areas to allow users to insert drinking straws into the packaging.
