  • Filled polystyrene tear back container lids
    Patent number: 7845514
    Abstract: The invention relates to tear-back thermoformed high impact polystyrene lids having from at least 10% to about 15% of filler and the specified configuration of the tear-back portion. In particular, the tear back lid comprises a tear back portion defined by two sets of tear back indentations and a left and a right notch cut into a skirt defined by the outer diameter of the lid. The combination of the filler amount and tear-back configuration allows an improved tearability for the filled polystyrene lids.
