ABSTRACT:
A drink through container lid of the type formed from thin thermoplastic material and which is used as a closure cap on open mouthed beverage cups is disclosed. Conventional lids of the foregoing description include one or more lines of weakness in the main body portion of the lid and which in part define the drink through segment of the lid. Normal breakage of this segment is initiated by hand at a location on the bottom of the skirt, which may or may not also include a lift tab projecting outwardly from the bottom of the skirt. In accordance with this invention, the lift tab is positioned above the bottom of the remainder of the skirt, and proximate to that portion of the outer wall of the groove of the lid which is in frictional engagement with the beverage cup to which it is attached. By locating the lift tab close to the area of frictional engagement of the lid to the cup, less force is required to initiate fracturing of the thermoplastic material in this area, and reduces the likelihood of the entire lid becoming separated from the container to which it is attached when only separation of the removable segment is desired. Means for further promoting the fracturing of the material can also be located at opposite ends of the lift tab.
