A container component with a wall section having means imparting a predefined and selectively weakened fracturable zone therein for conveniently opening the wall section in response to manually exerted force. The selectively weakened fracturable zone is provided by means of a pair of laterally interspaced channels defined in oppositely facing major sides of the wall section and which cooperate to define a fracturable partition, or bridge-wall, therebetween which extends between the oppositely facing major sides of the wall section. The channels further cooperate to impart a predefined lateral path of weakness extending therebetween through the partition. In response to manually applied force, the partition is adapted to fracture along the predefined lateral path of weakness and separate into a pair of overlapping ledges; one of which residually remains in accompaniment with each one of the resultant, residual free edges of the separated portions of the fractured wall section.
