- the annular projection 7 is deformed in contact with the opening end surface of the container mouth.
- the container mouth Due to the presence of the inner ring 6, outer ring 8, and annular protrusion 7, the container mouth is kept highly sealed. Since the resin cap 1 employs a one-piece structure that can seal the container mouth without providing packing, the manufacturing process is simplified as compared with a two-piece resin cap having packing.
- the two-piece structure provided with packing has a problem that it is difficult to clean the resin cap because there is a gap between the top plate and the packing.
- all are integrated, and there is no gap in the two-piece structure. Therefore, since the cleaning liquid reaches all the inside corners of the resin cap 1 in a short time, the cleaning liquid is easy to clean and can cope with aseptic filling.

If the outer end of each extension part and the inner ring are connected to each other, if the top plate or the side wall part is deformed due to some factor, and the rib is deformed accordingly, it is connected to this due to the influence of the deformed rib. The roundness of the inner ring is significantly reduced, and the sealing performance to the container mouth by the resin cap is lowered. In the resin cap 1 of the present embodiment, since the rib 13 and the inner ring 6 do not influence each other, the top plate 2 and the side wall 3 are deformed due to some factor, and the rib 13 is deformed accordingly.
