Abstract
In a plastic-coated cardboard milk or like container with a weakened area through which a straw is to be inserted, a pair of weakened lines surrounding such area on the inside and outside of the container respectively, the area enclosed by the line on the outside being smaller than the area enclosed by the line on the inside. This facilitates opening while resisting accidental opening under pressure from the inside.
