Definitions

  • a food merchandising package for a toaster-heated food product includes a substantially rectangular sealed pouch of heat conductive priable metal foil insertable into a toaster slot with a portion projecting outwardly of the toaster.
  • a pair of tear strips of insulating material extend in slightly spaced parallel relation transversely of the projecting portion and laterally to one side of the package, with a small clearance between adjacent edges of the strips, to provide insulated handling and pack age opening means.
  • a food product is sealed in the pouch.
  • One corner of the projecting portion is formed with a diagonally extending crease and the tabs are bevelled at their ends so that they substantially coincide with the diagonal tear line.
  • This invention relates to the packaging of commodities which are to be heated, while still in the package, before serving. More particularly, the present invention is directed to a novel handling and tear strip means for suchpackages by means of which the heated package may be withdrawn from a heating means, such as an electric toaster, grill, or the like, and opened without danger of the user being burnt or subjected to electric shock.
  • a heating means such as an electric toaster, grill, or the like
  • packages made of synthetic resin films are not particularly suitable when the food therein is to be heated directly, in the package and in the absence of liquid, before being served.
  • foods which are to be heated before serving while still in the package are the usual run of pre-cooked foods, which may be completely or partially pre-cooked.
  • Such foods maybe packaged in synthetic resin film material when they are to be heated by being placed in boiling water, for example.
  • the synthetic resin type of films are not suitable.
  • metal foils For the packaging of foods which are to be heated by more or less directly applied heat, as by being placed in an electric toaster, metal foils have been used for providing a sealed package. Such foils may include, for example, aluminum foil and other types of relatively thin metal foil.
  • One type of product which can be packaged in a metal foil package is the pre-broiled bacon disclosed and claimed in Zarotschenzeif U.S. Patent No. 2,807,550.
  • the advantage of a metal foil package for foods which are to be heated before serving by the direct application of heat is that the metal foil has a high heat conductivity and therefore ensures rapid and effective transmission of heat to the food sealed within the package.- Conversely, the very fact that the metal foil is highly heat conductive makes it difiicult for the user to handle the package, as may be necessary, for example, when removing the package from a toaster, broiler or the like. If the user attempts to grasp an end of a metal foil package ice which has been heated in an electric toaster, there is a very strong possibility of the user being burnt, as well as the risk of electric shock. Furthermore, tearing away of the end of a heated package made of metal foil or the like is rather difficult, particularly when the metal foil is hot or at a substantially elevated temperature.
  • An object of the present invention is to provide a food merchandising package for a food product to be heated,- before serving, as by placing the package in an ordinary electric toaster or broiler, and including novel handling and tear means projecting from the body of the package;
  • a further object of the invention is to provide a metalfoil food merchandising package for a food package to be heated before serving, and including heat and electric insulating means on a projecting portion of such package for the purposes of handling and tearing open the 'pack age.
  • a further object of the invention is to provide a metal foil food merchandising package for a food product to be heated, before serving, as by placing the package in an ordinary electric toaster, broiler or the like in which the metal foil package has a projecting portion, and a pair of juxtaposed, slightly spaced parallel strips of relatively stiff heat and electric insulating material extending transversely across the projecting portion and laterally beyond the side edge thereof to provide projecting handling tabs.
  • Yet another object of the invention is to provide a metal foil food merchandising package, of the type just mentioned, in which the strips of heat and electric insulating material are made, for example, of bonded asbestos fiber.
  • FIG. 1 is a front elevational view of a food merchandising package embodying the invention
  • FIG. 2 is a sectional view of the package, taken on the line 22 of FIG. 1;
  • FIG. 3 is a partial elevational view of the package as prepared for insertion of the slot of an electric toaster.
  • FIG. 4 is a somewhat perspective view illustrating the tearing off of the end of the package.
  • the package is generally indicated at 10 as comprising a pair of parallel walls 11.
  • the package is formed of a suitable metal foil, such as, for example, aluminum foil.
  • Parallel walls 11 either may be separate sheets of metal foil arranged in superposed relation, or may comprise a single strip of metal foil folded over medially of its ends.
  • the package has sealed side, lower and upper edges 12 extending inwardly to crease lines 13. Solely by Way of example, the commodities sealed within package 10 may comprise a series of prebroiled bacon strips 15, such as those produced by the method of the aforementioned Zarotschenzeff patent.
  • package -10 all four edges of package -10 are sealed, thus forming a sealed enclosure for 'bacon strips 15, so that a complete food merchandising package is provided for a food product which is to be heated, before serving, as by placing the package in an ordinary household electric toaster, broiler or the like.
  • the width of package 10 may be of the order of that of an ordinary household electric toaster, but the height of the package 10 is substantially greater than its width so as to provide an upper portion 14 which will project outwardly of the toaster, broiler, or the like when package 10 is inserted thereinto.
  • package 10 has a portion 14 which, when the package is placed into an electric toaster, broiler or the like, projects outwardly of the heating device.
  • a pair of tear strips 20a and 20b are secured to this upper portion so as to extend in slightly spaced parallel relation transversely of package 10.
  • Strips 20a and 20b have a very small clearance therebetween as indicated at 2-1. The strips extend laterally to one side of the package to form projecting tabs 22a and 22b for ease of handling of the package.
  • strips 2 a and 20b may be secured to either one or both of the walls 11, a preferred manner of attaching the strips is to bend the strips double and secure them to both walls 11, as by cementing, gluing, or otherwise bonding the strips 20a and 20b to the respective walls 11 of package 10.
  • the strips 20a and 20b and made of a suitable heat insulating material which is substantially a nonconductor of heat and electricity. Consequently, there is substantially no heat content in the strips 20a and 20b even after the package has been heated to preheat the food contents therein. Thereby, the package may be easily handled by grasping the tabs 22a and 22b between the thumb and forefinger, both for inserting the package into the heater and for removing the heated package from the heater.
  • tear strips 20:: and 2012 are made of a relatively stiff material compared to the relatively pliable metal foil of the package 10.
  • Suitable materials are asbestos-containing sheet material and the like.
  • a particularly suitable material is that sold under the trade name Quinorgo by I ohns-Manville. This is a thin flexible heatresistant electrical insulation material comprising purified asbestos fiber and a small amount of high temperature rubber binder, and having high thermal stability as well as good dielectric strength. Thereby any possibility of the user of the package being subjected to electric shock by virtue of a defect in the wiring of an electric toaster or broiler is obviated due to the dielectric properties of tear strips 20a and 20b.
  • Another suitable material is fiberglass.
  • the package 10 is formed with a diagonal crease 16 extending from the left edge, as viewed in FIG. 1, to the upper edge thereof.
  • the crease 16 forms an easy tear line
  • the left ends of tear strips 20a and 20b are formed with aligned beveled edges 23a and 23b which are substantially coincident with crease 16.
  • the corner of the upper portion 14 is torn off the crease line 16 before the package is inserted into the toaster. Thereby, tearing open of the heated package is greatly facilitated.
  • the package of the invention may be used with other foods which are to be heated directly either electrically or by flame, and is not limited to heating bacon or the like.
  • the portion of the package below the upper projecting portion 14 should have about the size and shape of a slice of bread although it may be a little higher than the average slice of bread.
  • the thickness can be of about the thickness of a usual slice of bread.
  • Suitable printing or the like may be impressed on the sides of the walls 11, if desired, and operating instructions can 'be printed on the tear strips 20a and 2012.
  • strip 20a may be labeled Tear olf corner before putting in toaster and strip 20b may be labeled To remove bacon, tear here and have an arrow pointing up to the gap between the tabs 22a and 22b.
