Abstract
A lid formed from plastics material and used as a closure for a drinking vessel is disclosed. The lid includes a main disc closure portion and a perimeter wall for mounting the lid on the open top end of the vessel. The lid is characterized by a rupturable depression in the main disc portion which receives and can be ruptured by one end of a drink through straw when pushed by hand. The depression has an annular sleeve like sidewall which terminates in a bottom end wall and which at their juncture provides a predetermined tear line. The depression also includes a formation in each portion of the side and bottom wall which extends from a first selected area of the sidewall in a direction towards another selected area in the sidewall which is spaced from the first area. The formation is engageable with the one end of the straw and when the straw is pushed into the depression, initiates rupture in the depression adjacent the second area.
