BOTTLE TYPE CAN WITH CAP AND ITS MANUFACTURING METHOD

To provide a bottle-type can excellent in both sealing performance and openability.SOLUTION: A top 8a has a top end 8b which is an upper end of a mouth part 4, an outer diameter maximum part 8c where an outer diameter is maximum below the top end 8b, an entrainment part 8d that continues downward from the outer diameter maximum part 8c and gradually decreases in the outer diameter and an outer peripheral wall part 8e connected to a lower side of the entrainment part 8d. The top end 8b, the outer diameter maximum part 8c and the entrainment part 8d form a smooth curved face. A curvature at a cross section of the outer peripheral wall 8e cut along a plane including a center axial line Lc of a mouth neck part 4 is "0" or "active" when the curvature of the entraining part 8d is "positive". An inflection part 8f is formed between the entrainment part 8d and the outer peripheral wall part 8e, the outer peripheral wall 8e whose curvature is "0" or "negative" has the outer diameter equal to or greater than the outer diameter of the inflection 8f.SELECTED DRAWING: Figure 5 【課題】密封性および開栓性が共に優れたボトル型缶を提供する。【解決手段】頂部８ａは、口首部４の上端である頂端８ｂと、頂端８ｂよりも下側で外径が極大となる外径極大部８ｃと、外径極大部８ｃから下側に続いており外径が次第に小さくなる巻き込み部８ｄと、巻き込み部８ｄの下側に繋がっている外周壁部８ｅとを有し、頂端８ｂおよび外径極大部８ｃならびに巻き込み部８ｄが滑らかな曲面をなし、口首部４の中心軸線Ｌｃを含む平面で切断した外周壁部８ｅの断面での曲率が、巻き込み部８ｄの曲率を「正」とした場合に「０」もしくは「負」となっていて、巻き込み部８ｄと外周壁部８ｅとの間に変曲部８ｆが形成され、曲率が「０」もしくは「負」となっている外周壁部８ｅは、変曲部８ｆの外径以上の外径になっている。【選択図】図５
