This creation provides a kind of Improvement type condom ring,Its ontology is bent in camber line,With bigger diameter end and miner diameter end,Bigger diameter end has large diameter hole,Miner diameter end has diameter holes,A hollow portion is formed between large diameter hole and diameter holes in what ontology,Ontology what has segmental arc in one adjacent to bigger diameter end,And neighbouring miner diameter end has an outer arc segments,This outer arc segments is carried over by the camber line of interior segmental arc,The end of miner diameter end towards being finished up in diameter holes in circular arc and form a lip,The outer ring week of outer arc segments forms a gentle ring end face adjacent to lip,Thereby constitute this creation.本創作提供一種改良式陰莖套環，其本體呈弧線彎折，具有大徑端與小徑端，大徑端具有大徑孔，小徑端具有小徑孔，大徑孔與小徑孔之間於本體內形成一中空部，本體於鄰近大徑端具有一內弧段，且鄰近小徑端具有一外弧段，此外弧段係由內弧段的弧線順沿，小徑端的端部朝向小徑孔中呈圓弧收尾且形成一唇部，外弧段的外環周鄰近唇部形成一平緩之環端面，藉此構成本創作。
