Abstract
A drink-through lid for beverage containers is disclosed in which a pre-scored drink-through section is included which is removable by squeezing gripping surfaces on opposite sides of a score line which fractures the score line and permits the section to be pulled from the lid while causing the score to initiate a tearing action through the peripheral bead cavity of the lid to facilitate such removal. A continuous thermo-forming and scoring process and apparatus are provided to manufacture lids with scored sections having a predictable response to applied squeezing pressure on the gripping surfaces.
