ABSTRACT:
A partial opening patch top closure member for containers is disclosed including at least one layer of monoaxially oriented synthetic plastic film the grain pattern of which extends in a given direction. The closure member includes body and tab portions so arranged relative to the grain pattern of the film that upon pulling of the tab portion, a section of the body portion is torn from the body portion along a line of tear parallel with the grain pattern, thereby leaving bonded to the container a residual body portion section containing a dispensing opening. Preferably the line of tear is at least partially defined by a tear-initiating cut contained in a juncture between the tab and body portions.
