Takeaway Container Question

Typically polystyrene takeaway containers have ridges on one of the two halves of the container. Should the ridge side be the lid or the base? More often then not they are used with the ridged half as the lid. I'd think though you'd want the ridged half as the base to collect condensate if the item were hot.

  1. Ha, I think about this all the time. We eat at the same Chinese restaurant every week and we always have leftovers and they just give you the containers to pack up by yourself.

    I usually put the ridged side on the top because I don't want the sauces to get caught in the ridges.

    I bet there is a reason for the ridges; who knows.

      If you were to put a piece of hot/warm cooked meat on the ridges, it would not end up sitting in ts juices or fat that has run off.

        That's what I think the ridges are for as well. Yet invariably shop owners (particularly Chinese restaurants) close the containers with the ridges up. Just a pet peeve.

          Is the ridge side also the side with the tongue that goes through the slit to hold the lid shut ? I prefer to close the box with the tongue side on top because I'm afraid of the tongue unlatching from the slit and dumping all the food on the ground.

            exactly dump, the lid of a clamshell container has the tabs, the bottom has the slots. the ridges are not a factor.
