PROBLEM TO BE SOLVED: To provide a resin-made mouthpiece member for a storage container which neither rusts nor generates a gap. SOLUTION: This relates to a resin-made mouthpiece member to be fixed on the spout of a storage container. The member comprises a fixing part to be fixed on a mouthpiece member mounting part formed on the peripheral edge of the spout of the container on its bottom, a caulking protrusive part formed protrusively on the inside edge of the fixing part, and a crown cap mounting part formed on the top of a mouthpiece member main body having a larger diameter. The fixing part is inserted and placed on a mouthpiece member placing part formed recessed on the mouthpiece member mounting part of the container. By erecting the inside peripheral edge of the placing part of the container vertically and by folding the top of the inside peripheral edge outward, the caulking protrusive part inserted and placed is caulked and fixed by the folded top of the inside peripheral edge to be integrally fixed on the spout of the storage container.
