Help! Need the name of a cap

As many years as I have worked in the laboratory industry, I do not know the name of a specific cap I need to order. It is a screw cap with an open/close valve and septa to minimize evaporation and exposure. Does anyone know if it has a standard name? I'd really appreciate the assistance!
