摘要： A membrane for sealing an open spout of a food package is provided. The membrane comprises a central circular disc member (202), an outer annular disc member (204) connected to said central circular disc member (202) along its inner periphery at a connection angle (±), and a resilient tubular portion (208) extending between a first open end (210) and a second end (212) being connected to the outer annular disc member (204), the diameter of said second end (212) being smaller than the outer diameter of said annular disc member (204), wherein the annular disc member (204) is pivotable relative the central circular disc member (202) for increasing the diameter of the second end (210) of said tubular portion (208) by changing said connection angle (±) and wherein membrane is connected to a neck of the food package by means of a cut-off area extending along the entire periphery of the neck.
