Abstract: The invention refers to a capsule for preparing infusion beverages and a capsule production method. The capsule includes an outer containing body defining a longitudinal direction and a cover for forming a first inner chamber. The capsule has also a first inner duct extending in the longitudinal direction towards the inside for fluidly connecting the first inner chamber with the outside. The capsule has also an inner containing body with a second end wall, separate from the outer containing body. The inner containing body is arranged upside down, inside the outer containing body. The second inner chamber is fluidly connected with said first inner chamber. The capsule includes a closing layer for closing the inner containing body at the second end wall in a fluid-tight manner.
