Abstract
A vacuum-formed lid for a large drinks container is disclosed made from extruded sheet plastic. The lid has provision for the user to remove a tear-out portion to leave a hole through which liquid may be poured out of the container. The lid includes a ridge which is gripped between finger and thumb. A slit is located just under the thumb, so that squeezing the ridge is effective to open the slit. The slit runs across the "grain" of the extruded plastic. The effect is that tearing the lid can be easily accomplished, yet the tear may be directed and controlled easily.
