A bottle sealing cover is mounted on a bottle mouth of a bottle, the bottle mouth having an upper end ring surface, the bottle sealing cover comprising a bottle body and an elastic pad, the bottle body having a recessed space and a spiral structure The recessed space has an inner top surface, and the elastic pad has a shape corresponding to the inner top surface and is attached to the inner top surface, the recessed space covers the bottle mouth and the spiral structure is locked to the bottle mouth. Pressing the elastic pad to press the upper end ring surface, and the elastic pad closes the bottle mouth, and the elastic pad integrally extends a tab away from the inner top surface； accordingly, The elastic pad can be made of a soft material, and can be deformed due to the height difference on the upper end ring surface to surely seal the bottle mouth, and the elastic pad can be easily pulled and removed by the design of the tab. Fully cleaned to meet hygienic use requirements.一種奶瓶密封蓋，安裝於一奶瓶的一瓶口，該瓶口具有一上端環面，該奶瓶密封蓋包含一瓶蓋體與一彈性襯墊，該瓶蓋體具有一凹陷空間與一螺旋構造，該凹陷空間具有一內頂面，該彈性襯墊對應該內頂面的形狀且貼覆於該內頂面上，該凹陷空間罩覆該瓶口且該螺旋構造鎖固於該瓶口，以讓該彈性襯墊變形的壓迫於該上端環面上，而讓該彈性襯墊封閉該瓶口，並該彈性襯墊一體延伸出一遠離該內頂面的凸片；據此，由於該彈性襯墊可以選用軟性材質，而可因應該上端環面上的高低落差而變形，以確實密封該瓶口，且藉由該凸片的設計，可以輕鬆的拉扯該彈性襯墊而取下，以充分進行清洗，滿足衛生的使用要求。
