Splash proof drink-through beverage container lid

A flexible plastic lid for open mouthed containers having an annular bead or rim defining the open mouth thereof, comprising:

• a rim receiving annular bead cavity formed in the outer periphery of said lid and having an upper surface for overlying a container rim and a dependent annular skirt outboard of said upper surface;
• a central web portion bounded by said bead cavity having a raised area defined therein connected to and at substantially the same level as said upper surface;
• and
• finite score line means formed in said raised area substantially transversely oriented there across to subtend a given peripheral portion of said bead cavity, the length of said score line means defining the transverse dimension of a tear-tab means in said raised area;
• and
• said tear-tab means in said raised area being responsive to an upward and outward pressure thereon at said score line means to cause said tear-tab means to predictably tear away from said raised area and through said bead cavity to remove said given peripheral portion;
• said tear tab means having a substantially steep-walled cavity defined therein adjacent said dependent annular skirt and having an external wall cooperating with said skirt defining a container rim gripping means for removably supporting said tear-tab on a container rim independently of the remainder of said lid.

A friction fit sheet plastic lid for open mouthed containers having a peripheral lid receiving rim portion about the mouth thereof comprising:

• a peripheral rim receiving cavity defined therein;
• a central web bounded by said rim cavity;
• a raised area formed in said central web;
• an upper surface on said rim cavity at substantially the same height as said raised area and merging therewith over at least a predetermined peripheral portion;
• and
• a wedge shaped tear-away section having a tear-tab at its innermost extremity defined by score lines which diverge to substantially subtend said predetermined peripheral portion and which terminate substantially inboard of said upper surface of said bead cavity;
• said tear-away section and said predetermined peripheral portion being removable from the remainder of said lid by an upward and outward force on said tear-tab;
• said tear-away sections including container rim gripping means for replaceably securing said tear-away section on the rim of an associated container independently of the remainder of said lid.

• an upper surface on said rim cavity at substantially the same height as said raised area and merging therewith over at least a predetermined peripheral portion;
• and
• a tear-away section having a tear-tab at its innermost extremity defined by a score line configuration which substantially subtends said predetermined peripheral portion and which terminates substantially inboard of said upper surface of said bead cavity;
• said tear-away section and said predetermined peripheral portion being removable from the remainder of said lid by an upward and outward force on said tear-tab;
• said tear-away sections including container rim gripping means for replaceably securing said tear-away section on the rim of an associated container independently of the remainder of said lid.
