Abstract
Abstract A method of making individual serving packages in which a sheet is sealed around the rims of a plurality of cups formed in a single sheet. After sealing, the cups are cut away from the sheet with the cover sheet sealed to them. The initial sheet containing the cups has a slit which causes a tab to be formed when the completed packages are severed from the sheet.

Claim 1
Independent Claim

A method of making a plurality of easily opened packages comprising placing a commodity in each of a plurality of receptacles in a sheet, each receptacle comprising a bottom and at least one sidewall extending upwardly from the bottom, the upper end of said sidewall being integral with said sheet and the sheet occupying all of the area between and around the several receptacles, said sheet being cut at least part of the way through its thickness along a plurality of score lines each of which score lines is adjacent to one of said receptacles and transverse to a line through the center of the receptacle to which it is adjacent, said score lines being spaced outwardly from the upper ends of the sidewalls of the receptacles to which they are, respectively, adjacent, sealing a sheet material to said sheet in at least a continuous ring around the mouth of each receptacle, said ring including areas of said sheet on both sides of the receptacle around which the ring extends, and severing said sheet and sheet material along a pluraLity of perimeter lines, each perimeter line extending completely around one of the receptacles and being spaced outwardly from the mouth of the receptacle around which it extends to form from said sheet, between the top of the sidewall of that receptacle and the perimeter line, a flange extending outwardly from the mouth of the receptacle to the perimeter line and the score line, at least a portion of the continuous sealed ring around each receptacle being between the mouth of that receptacle and the perimeter line around it, so that each said flange is sealed to said sheet material, each of said perimeter lines crossing the score line adjacent the receptacle around which it extends in two places spaced along, that score line to form a tab between the perimeter line and the score line, from a portion of said sheet adjacent the flange said continuous ring including at least a portion of the area of said sheet which forms said tab so that the tab is sealed to the sheet material.

Dependent Claim
37 words
A method as set forth in claim 1 in which said sheet is cut through along said score lines to form a slit, so that said tabs are attached to said flanges only by said sheet material.
