Abstract: A hygienic bottle cap for connection to a fluid container includes a skirt and a crown portion having a cylindrical wall with an upper portion and a lower portion and forms a central well. A flapper forming a portion of the bottom surface of the center well is attached to the cylindrical wall. A score line is formed partially around the perimeter of the flapper between the flapper and the cylindrical wall, and the portion of the perimeter that is not scored remains intact upon insertion of a probe. The flapper may be separated from the cylindrical wall by the probe, and may return to its initial sealed position after the probe is retracted. In one embodiment, a protrusion is supported on an underside of the flapper in order to facilitate separation of the flapper from the cylindrical wall along the score line.

Abstract: A hygienic bottle cap for connection to a neck of a fluid container includes a skirt and a crown portion which includes a cylindrical wall having an upper portion and a lower portion and forms a central well. A flapper forming a portion of the bottom surface of the center well is attached to the cylindrical wall via two separate tab points. A score line is formed partially around the perimeter of the flapper between the flapper and the cylindrical wall and the portion of the perimeter that is not scored remains intact upon insertion of a probe. Alternatively, the flapper may be attached to the cylindrical wall via a bridge portion. The flapper may be separated from the cylindrical wall by the probe and the flapper may return to its initial sealed position after the probe is retracted due to the memory characteristics of the material connecting the flapper to the cylindrical wall.
