摘要： A tool assembly is disclosed for forming a plastic container having a hinged lid which is produced from a single sheet of plastic material. The tool comprises two die members, one of which comprises two cavities over which a plastic sheet is laid and a second die member for cooperation therewith for vacuum forming the two container portions in the conventional manner with a connecting portion of plastic sheet material therebetween. At least one of the die members includes cutting members for separating the formed container from the remainder of the sheet material and also includes at least one elongated projection for compressing and causing local thinning in the connecting portion to form a hinge as the dies move together.
