Abstract: A bottle includes a reservoir including protrusions on a neck, each protrusion having a horizontal latch, an inclined surface on a bottom of the latch, and a recess between the inclined surface and the protrusion; a cap including an inner top wall, an internal annular wall, and projections on an inner surface of the annular wall; and a disc shaped sealing member including a raised edge and flexible elements on a top. The sealing member is in the cap to engage the open ends of the flexible elements with the top wall and rest the raised edge on the engagement surfaces of the projections. In response to rotating the cap on the neck, the projections ride along the inclined surfaces to be locked in the recesses, the open ends of the flexible elements urge against the top wall, and the sealing member is airtightly disposed on the neck.
