Abstract
The valve includes a female part having a closed, transverse, proximal end wall, and a tubular wall integral with a flange part, a lateral opening being formed on the proximal section of the tubular wall, a male part having a tubular wall forming, on the proximal side, a closing/opening part having an open, transverse, proximal end; the closing/opening part has an external shape and an external dimension that fit the internal shape and internal dimension of the proximal receiving part of the female part. The sealing elements include three ring seals separated from one another in an axial direction, supported by the upper surface of the tubular wall of the male part and engaging with the female part, a proximal seal to the fluid product, a distal seal to external contaminants, and an intermediate seal to the fluid product and to external contaminants between the proximal and distal seals.
