Patent number: 4126244Abstract: 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.Type: GrantFiled: August 30, 1977Date of Patent: November 21, 1978Assignee: Owens-Illinois, Inc.Inventor: William F.

Patent number: 4117945Abstract: A child-resistant, safety closure for a container having a dispensing end including a threaded neck portion. The closure features an inner sidewall threadably attachable on the container neck portion and an outer sidewall having a flexible and resiliently distensible distal end portion with at least one interlocking member adapted to automatically interlockingly engage the dispensing end of the container when the closure is in either a fully closed or in at least one additional, partially removed position on the container neck portion. Removal of the closure requires manual compression of the outer sidewall at locations straddling the interlocking members, coupled with concurrent retrogressive movement of the closure. Ordinarily, such manual manipulation must be repeated at each interlocking position of the closure. Moreover, as a further safety factor, the interlocking members are inaccessibly and unobservably secluded within the interior confines of the closure when it is interlocked on the container.Type: GrantFiled: June 29, 1977Date of Patent: October 3, 1978Assignee: Owens-Illinois, Inc.Inventor: George V.
