Abstract
Method and apparatus for packaging sliced bacon and the like comprises placing a shingle of bacon strips on a tray formed of a unitary sheet of thin, semi-rigid, impervious plastic material having an integral flap along one side, heating said material along a fold line between the flap and tray, folding the integral flap over an edge portion of the shingle of sliced bacon on the tray, and applying a permanent set to the folded flap to permanently overlie said edge portion of said shingle of bacon.
Claims12
A method of packaging sliced bacon strips arranged in shingled relation in a bacon shingle comprising the steps of first placing a shingle of sliced bacon on top of a body portion of a flat sheet of semi-rigid impervious styrene plastic material having an integral flap formed along a fold line between said body portion and said flap with an edge of said shingle closely adjacent said fold line, heating said plastic material only in a narrow trough formed along said fold line to an elevated bending temperature, folding said flap along said fold line over and downwardly toward an edge portion of said shingle of sliced bacon on said body portion and applying pressure to said fold line to effect a permanent set to said folded flap to permanently overlie said edge portion of said shingle of bacon.
Apparatus for making packages for shingles of sliced bacon strips from unitary sheets of flat semi-rigid impervious styrene plastic material having an integral flap along an edge of a body portion defining a fold line, said apparatus comprising means for supporting said sheets with shingles of bacon thereon for movement in sequence along a work path to form said packages, means for moving said sheets loaded with said sliced bacon thereon along a path, means for guiding said loaded sheets aligned with the fold lines thereof along said path, means for heating said sheets only in a narrow groove along said fold lines during movement along said path, means for folding said flaps along said fold lines over and downwardly toward an edge portion of the bacon shingle on said body portion while heated to bending temperature and means for forming a permanent set to said folded flaps overlying said edge portion of said bacon shingle on said body portions.
