Patent number: 5474728Abstract: The invention relates to a mold apparatus and a process for forming a lid latching mechanism in a thermoplastic container. The lid latching mechanism features a large, trapezoidally-shaped opening hole. The trapezoidal shape has been found to reduce the amount of tearing that can occur along the edges of an opening formed during the thermoforming process. The opening is created by the engagement between a fixed shear key mounted in a first mold member and a movable shear key which has a trapezoidally-shaped cutting surface and is mounted in a second mold member. The movable key travels along an inclined path as the mold members close on a preheated thermoplastic sheet to form a container.Type: GrantFiled: July 11, 1994Date of Patent: December 12, 1995Assignee: Mobil Oil CorporationInventors: Glenn C.
