Abstract
An example of a door with a pliable curtain includes various washdown features that make the door particularly suitable for use in food and drug related environments that demand cleanliness. To prevent product contamination, such as bacteria and other microorganisms, some examples of the door include a curtain storage track with a spiral groove machined in a unitary block of plastic, a ventilated side frame with a removable curtain guide track and a removable seal, and various curtain seams that not only join multiple sheets of the curtain together but also promote and strategically direct liquid runoff to avoid creating water-holding surfaces and to prevent liquid from dripping on products passing through the doorway.
