Abstract
A disposable plastic lid including a depending skirt formed with stacking, sealing and snap rings, and a pull tab at the lowermost edge of the skirt. The lid is formed such that the plastic is uniaxially oriented in a first direction and the tab is located to initiate a tear in a second direction transverse to the first direction. Tearing is also facilitated by notching the pull tab at either end thereof, and by providing a surface projection interrupting the snap ring in an area immediately adjacent the pull tab.
