Definitions
- the present invention relates generally to packages for use in microwave ovens, and pertains more particularly to an expandable bag having protection from grease leaking and/or wicking from its expansion creases or folds and/or to a flexible popcorn package made from a single layer of greaseproof paper.
- the packages When microwave popcorn packages were first introduced utilizing a microwave susceptor, the packages typically were formed by expandable paperboard containers and often the load of the microwave popcorn popping package was located in a plastic bag positioned inside of the
- plastic bags are susceptible to melting and often are difficult to handle with a hot food product at least due to the poor insulating qualities of plastic.
- microwave susceptors applied in the form of a thin coating such as disclosed in U.S. Patent No. 4,267,420 issued to William A. Brastad, the microwave popcorn industry has turned to popcorn packages formed from flexible paper bags.
- the load of a microwave popcorn popping package includes unpopped popcorn kernels, a cooking oil or grease, salt, and other ingredients such as colorings, flavorings, or the like.
- the oil and/or grease have a tendency to leak from flexible paper packages, especially at high temperatures, causing aesthetically unpleasant appearances.
- the oil and/or grease have a tendency to wick from flexible paper packages.
- Current flexible paper popcorn bags typically use a tri-laminate of a greaseproof paper adhered to an outer fluorocarbon treated, grease resistant paper with a microwave susceptor sandwiched between.
- the inner layer could be formed of bleached greaseproof Kraft paper of 25 lb./ream basis weight and the outer layer could be formed of plain bleached Kraft paper of 30 lb./ream basis weight.
- the two paper layers and the adhesive there- between together provide the needed grease barrier in both storage and/or transportation at high temperatures as well as during microwave cooking.
- laminated paper popcorn bags suffer from several disadvantages. First, the paper bag has a great deal of stiffness resulting from the multiple layers themselves but also their adhesive interconnection. Stiffness detracts from the ability of the bag to inflate or expand during microwave popping of the popcorn which may in turn detrimentally affect the volume of the popped kernels.
- the problem of grease wicking and actual leaking is especially present at folds and creases where the fibers of the paper and coatings applied thereto for the greaseproofing characteristics are fractured and/or separated.
- This problem has been one of the major factors in limiting the amount that the material and/or number of layers can be reduced in flexible paper popcorn bags, as the mass and number of layers of material are relied upon to provide the needed grease barrier.
- a package in the form of a bag including grease protectors for sealing the surfaces of the walls of the bag adjacent to their connecting, folding edges to prevent the grease or oil from leaking or wicking from the interior volume of the bag.
- the package includes pleated, expandable side walls, with the grease protectors located inside of the bag where the inside surfaces of the pleats overlie other inside surfaces of the bag and also located outside of the bag where the outside surfaces of the pleats overlie other outside surfaces of the bag.
- the bag holds popcorn kernels and grease or oil for popping in a microwave oven, with the bag formed of a single layer of greaseproof paper having a thickness allowing the single layer to be flexed by the popping of the popcorn kernels and also preventing the wicking and leaking of the grease or oil through the single layer.
- Figure 1 shows a perspective view of a package fabricated in accordance with the preferred teachings of the present invention in generally its collapsed, storage condition, but illustrated slightly expanded to show constructional details.
- Figure 2 shows a top plan view of the package of Figure 1, with portions broken away to show constructional details.
- Figure 3 shows a perspective view of the package of Figure 1 in its expanded condition.
- Figure 4 shows a cross-sectional view of the package of Figure 1 in a condition slightly prior to its expanded condition of Figure 3.
- bag 18 includes a bottom wall 20, a top wall 22, an end wall 24, side walls 26 and a closed end 28.
- the width of bottom wall 20 is less than the width of top wall 22, although the widths of walls 20 and 22 could be equal.
- End wall 24 provides a non-opening permanent seal to the first end of bag 18.
- the cross sectional makeup of end wall 24 includes a number of folds that are not important to an understanding of the present invention so will not be specifically described, although end wall 24 should be constructed so as to seal adequately the vapor created within bag 18 during the heating thereof in the microwave oven.
- end wall 24 is shown as being of the type shown in U.S. Patent No.
- end wall 24 can have a flat rectangular or square configuration, with such bags being commonly referred to as square bottom bags in the trade.
- bag 18 can optionally include the non-heated flap of the type shown and described in U.S. Patent No. 4,864,090.
- end wall 24 can be a variety of types and configurations such as but not limited to the types shown in U.S. Patent Nos. 3,973,045; 4,450,180; 4,691,374; and 5,044,777.
- side walls 26 include gussets or pleats 26a, 26b, 26c and 26d that enable side walls 26 to expand during a heating cycle.
- pleats 26a and 26b are connected together at first edges and have second and third, opposite edges connected to bottom wall 20 and top wall 22, respectively.
- pleats 26c and 26d are connected together at fourth edges and have fifth and sixth, opposite edges connected to bottom wall 20 and top wall 22, respectively.
- pleats 26a and 26c in its collapsed condition, pleats 26a and 26c have the same width and overlie bottom wall 20, and pleats 26b and 26d have the same width which is greater than the width of pleats 26a and 26c and overlie pleats 26a and 26c, with top wall 22 overlying pleats 26b and 26d.
- bottom and top walls 20 and 22 have a width extending beyond the interconnections of pleats 26a and 26b and of pleats 26c and 26d when bag 18 is in its collapsed condition.
- the second, free ends of pleats 26a, 26b, 26c and 26d forming side walls 26, of bottom wall 20, and of top wall 22 are co-planar, and have the same extent or length from end wall 24.
- End 28 provides a peelable closure seal which fails during microwave cooking adjacent the second, free ends of bottom, top and side walls 20, 22, and 26 or in other words, adjacent the second end of bag 18. This peelable seal failure allows trapped steam to vent from the package, as well as allowing the consumer to open bag 18 after microwave cooking and prior to eating.
- end 28 is formed in a manner as shown and described in U.S. Patent Application No. 07/834,187 filed February 2, 1992, which is hereby incorporated herein by reference, and includes first and second V-shaped adhesive strips 34 and 36.
- Strip 34 is located on bottom wall 20 having first and second, straight legs 34a and 34b interconnected by their first ends at an angle in the order of 140° and having their second ends extending to the interconnection of pleats 26a and 26c to bottom wall 20, respectively.
- Strip 36 overlies strip 34 and is located on top wall 22 having first and second, straight legs 36a and 36b interconnected by their first ends at an angle in the order of 140° and having their second ends extending to the interconnection of pleats 26b and 26d to top wall 22, respectively.
- leg 34a adheres and seals pleat 26a to bottom wall
- leg 34b adheres and seals pleat 26c to bottom wall
- leg 36a adheres and seals pleat 26b to top wall
- leg 36b adheres and seals pleat 26d to top wall 22.
- strips 34 and 36 adhere and seal bottom wall 20 to top wall 22 at their central portions 37 intermediate the interconnections of pleats 26a and 26b and of pleats 26c and 26d.
- Areas 38a, 38b, 38c and 38d are formed and defined by the material between the free ends of walls 20, 22, and 26 and strips 34 and 36 and located on the opposite side of strips 34 and 36 forming the peelable seal than end 24, with areas 38a, 38b, 38c, and 38d being free of adhesive and unsealed in the preferred form. Due to the angular orientation of legs 34a, 34b, 36a, and 36b, areas 38a, 38b, 38c, and 38d are of a triangular configuration.
- legs 34a, 34b, 36a, and 36b are located in the central portions 37 of bottom and top walls 20 and 22 having widths extending beyond pleats 26a, 26b, 26c, and 26d and since legs 34a, 34b, 36a and 36b extend therefrom in a linear manner at an obtuse angle to the opposite edges of pleats 26a, 26b, 26c, and 26d, areas 38a, 38b, 38c, and 38d are of a large size for grasping by the consumer and specifically are considerably larger than flaps formed by adhesive extending at small angles relative to each other and only through the pleats such as when a box-like shape is desired as disclosed in U.S. Patent 5,044,777.
- end 28 can be a variety of types and configurations according to preferred aspects of the present invention such as but not limited to the types shown in U.S. Patent Nos. 3,973,045; 4,450,180; 4,691,374; 4,864,090; 4,973,810; and 5,044,777. Attention is now directed to a susceptor pad 30 that extends over a portion of bottom wall 20 spaced from end wall 24 and end 28. Susceptor pad 30 can be formed in any suitable manner known in the art such as a metalized plastic film adhered to bottom wall 20, as a paper backed susceptor, or as a coating applied or printed to bottom wall 20.
- susceptor pad 30 is shown as overlying bottom wall 20 and thus located inside of bag 18, susceptor pad 30 can be located outside of bag 18 with bottom wall 20 overlying susceptor pad 30. Further, placement of susceptor pad 30 can occur at the material convertor or on the manufacturing lines.
- bag 18 can be manufactured as current bags are manufactured for example of the type shown and described in U.S. Patent Nos.
- bag 18 can be formed by cutting a web of material to length, folding that length of material to form the tubular bag stock including bottom, top, and side walls 20, 22, and 26, and then forming end wall 24 by folding and adhering bottom, top and side walls 20, 22, and 26. It should be noted that the overlapping edges of the web of material forming the tubular bag stock has been omitted in Figures 1-3 for ease of illustration. It should also be noted that the free, second ends of bottom, top, and side walls 20, 22, and 26 are all of the same length and specifically do not require any special cuts and/or do not require extra components to form tabs or flaps.
- bag 18 can be filled with the desired food product as current bags are filled for example of the type shown and described in U.S. Patent 4,450,180. After filling, strips 34 and 36 can be adhered to walls 20, 22, and 26 utilizing standard equipment presently utilized to form the peelable seal of current bags. It of course should be appreciated that the particular manner of manufacture and filling of bag 18 can be done in a variety of ways and manners such as but not limited to the example set forth above.
- bag 18 is popcorn kernels and the popped kernels have been generally indicated by the reference numeral 40, having been popped when in the microwave oven.
- bag 18 in a collapsed condition is placed in a microwave oven with bottom wall 20 resting upon the bottom surface of the oven cavity.
- susceptor pad 30 converts microwave energy into heat, with the heat and remaining microwave energy causing the popping of the kernels and the creation of water vapor.
- bag 18 is formed of a single layer of greaseproof paper having a thickness allowing the single layer to be flexed by the popping of the popcorn kernels and also providing adequate greaseproof properties in storage, transportation, or cooking throughout the thickness of the paper to prevent wicking and leaking of grease or oil through the single layer. It has been discovered that by the selection of raw fibers as well as highly refining the raw fibers in the process of making the paper, the fibers themselves in the paper are resistant to grease staining and gives the paper greaseproof properties even when folded or creased.
- the highly refined fibers have less tendency to fracture revealing uncoated fiber ends which absorb grease, but rather the bonds between the fibers tend to stretch, bend, or fracture and thus not revealing fractured fiber ends.
- Specifically raw fibers selected from the group of 100% chemical softwood pulp such as 100% bleached Kraft softwoods and which are highly refined to a freeness level in the order of 150 to 250 cubic centimeters have been found to provide adequate greaseproof properties when formed into paper having a basis weight of 25 lb./ream to 45 lb./ream and in the most preferred form in the order of 35 lb./ream.
- bag 18 is formed of a single layer of paper. Code No. 220-3510 produced by Rhinelander Paper Company, 515 W.
- bag 18 according to the teachings of the present invention is much more flexible than current conventional popcorn bags because of its single layer and elimination of the laminating adhesive. Further, benefits of the single layer of paper softening during microwave cooking due to heat and steam give bag 18 more flexibility and less stiffness. Due to this increased flexibility, bag 18 according to the preferred teachings of the present invention inflates or expands from its collapsed, storage condition to an inflated or expanded condition having a larger interior volume than the same size current conventional popcorn bags, with bag 18 of the present invention allowing the popped kernels to pop with greater volume.
- the single layer forming bag 18 provides economic advantages over current multilaminate popcorn bags by reducing the amount of paper material used for each bag 18 and also by eliminating the adhesive and the laminating steps required in multilaminate popcorn bags. Additionally, with the reduction in the amount of paper material used for each bag 18 and the elimination of the laminating adhesive, less package material in the form of garbage after the consumption of the popcorn is required to be disposed of resulting in environmental advantages over multilaminate popcorn bags.
- Bag 18 provides an added option of provisions for built-in grease leak protection at the creases.
- grease protectors 42a, 42b, 42c, and 42d are provided located inside of bag 18 for sealing bottom wall 20 to pleat 26a, top wall 22 to pleat 26b, bottom wall 20 to pleat 26c, and top wall 22 to pleat 26d, respectively, adjacent to their respective connecting edges, with grease protectors 42a, 42b, 42c, and 42d sticking or joining the inside surfaces of bottom wall 20 to pleat 26a, top wall 22 to pleat 26b, bottom wall 20 to pleat 26c, and top wall 22 to pleat 26d, respectively, together adjacent to their respective connecting edges.
- grease protectors 44a and 44b are provided located outside of bag 18 for sealing pleat 26a to pleat 26b and pleat 26c to pleat 26d, respectively, adjacent to their respective connecting edges, with grease protectors 44a and 44b sticking or joining the outside surfaces of pleat 26a to pleat 26b and pleat 26c to pleat 26d, respectively, together adjacent to their respective connecting edges.
- grease protectors 42a, 42b, 42c, 42d, 44a and 44b are applied during the printing process in the form of strips of preapplied heat seal adhesive on one or both sides of the connecting edges or of strips of preapplied cohesive on both sides of the connecting edges, such as Duraset 12, or equivalent.
- Grease protectors 42a, 42b, 42c, 42d, 44a and 44b are selected to actually seal the paper forming bag 18 together just above and adjacent the connecting edges.
- Grease protectors 42a, 42b, 42c, and 42d actually block the flow of grease to the folded or creased areas of the connecting edges, and grease protectors 44a and 44b block the flow of grease away from the folded or creased areas of the connecting edges, thus preventing grease wicking or leaking.
- the adhesive or cohesive forming grease protectors 42a, 42b, 42c, 42d, 44a and 44b is selected to release or peel during expansion or inflation of bag 18 during microwave cooking such that the expanded or inflated volume of bag 18 will not be reduced utilizing grease protectors 42a, 42b, 42c, 42d, 44a and 44b from the expanded or inflated volume of bag 18 not utilizing grease protectors 42a, 42b, 42c, 42d, 44a and 44b.
- grease protectors 42a, 42b, 42c, 42d, 44a and 44b provide an added grease barrier at the folded and creased areas where grease wicking and leaking are especially a problem, with grease protectors 42a, 42b, 42c, 42d, 44a, and 44b allowing minimization of the material and/or number of layers forming bag 18 where grease wicking and leaking are not such a problem.
