<p>A cap for a molded plastic container has a generally U-shaped groove of diminished cross section in its cover portion that defines a tab that is depressible to provide drinking access. The tab is provided with a raised block to facilitate the tearing free of the tab along the groove upon application of pressure to the block. The depressible tab remains hinged to the cap, and the leading edge of the block locks beneath the surface of a portion of the cap adjacent the access opening. The elevation of the block relative to the surface of the tab is such that when the tab is depressed and the block is locked, all of the tab and a substantial portion of the block are positioned below the remaining cap surface to establish an opening at that surface for pouring or drinking purposes.</p> |
