  • Figs 1 and 2 illustrate a resealable bag useful for marinading food according to a preferred embodiment of the invention.
  • the generally rectangular resealable bag 10 has a flexible top plastic sheet 12 and a flexible bottom foil sheet 14, sealed together along the periphery of the sheets.
  • the bag 10 has sealed ends 16 and 18 and sealed opposed sides 20 and 22.
  • the sheets 12 and 14 are formed of food-safe materials.
  • the sheets 12 and 14 preferably have good oxygen barrier properties to keep any food within the bag fresh.
  • the flexible plastic sheet 12 is preferably transparent, so the contents of the bag may be seen.
  • the reclosable closure 24 and the sealed end 16 of the bag 10 define a openable region 40 therebetween.
  • the recloseable closure 24 may be of the type referred to as a "zipper lock" closure, and may be formed by applying a polymer strip to the inside face of each sheet 12 and 14, each polymer strip having an integrally formed rib, the ribs having interengaged male and female portions whereby the ribs can be connected to one another along their length.
  • each of the sheets 12 and 14 may have an integrally formed rib, the ribs having interengaged male and female portions whereby the ribs can be connected to one another along their length, making the application of the polymer strips with ribs unnecessary.
  • the recloseable closure 24 resists tearing, so food and marinade within the bag do not leak from the bag 10.

  • the rupturable seal 30 is arcuate in shape, as illustrated in Figure 1, and extends from one sealed opposed side 20 to the other sealed opposed side 22, so that the top of the arch 32 is located in a central region between opposed sealed sides 20 and 22, so the top of the arch 32 is closer to the reclosable closure 24 than are the ends of the arch 34 and 36.
  • the arcuate shape of the rupturable seal 30 causes a stress concentration in the rupturable seal 30 at the central region when bag is opened, so the sheets joined by the rupturable seal 30 are more easily separated than they would be if the rupturable seal were straight.
  • an effective depth d for the arcuate seal is approximately 1 inch, although other depths and degrees of curvature may also be used.
  • the rupturable seal 30 defines a central compartment 50 between the rupturable seal 30 and the recloseable closure 24, and defines a marinade storage compartment 60 between the sealed end 18 and the rupturable seal 30.
  • a marinade 65 is stored in the marinade storage compartment 60.
  • a marinade is an edible substance which can impart a flavor or flavors to a food.
  • the marinade 65 is preferably liquid or liquid-like.
  • the marinade may alternatively be dry and may, for example, be a dry mixture of seasonings.
  • a food storage compartment 70 is defined by the reclosable closure 24, the sealed end of the bag 18, and the sealed opposed sides of the bag 20 and 22.
  • Notches 42 and 44 are preferably provided in the peripheral seal on the opposed sides 20 and 22 in the openable region of the bag 40, to provide a tearable end for the bag, the tearable end being positioned outside of the recloseable closure 24.
  • the bag 10 may be folded into thirds for convenience, by folding the ends of the bag 18 and 16 toward the center of the bag 10 in an overlapping manner.
  • a thin plastic layer 15 is located on an inner face of the flexible foil sheet 14, arranged so the plastic layer 15 and the flexible plastic sheet 12 form the inside of the bag 10, and the plastic layer 15 and the flexible plastic sheet 12 will be in contact with food and marinade in the bag 10.
  • the peripheral edges of the of the sheets 16, 18, 20, and 22 may be sealed by adhesion, by fusion of the thermoplastic materials (heat-sealed), or other appropriate method as will be readily appreciated by those of skill in the art.
  • the rupturable seal 30 is approximately straight rather than arcuate and is approximately parallel to the recloseable closure
  • the end 18 of the bag 10 is not sealed, and the marinade storage compartment 60 is empty, so that marinade or other items may be placed in the marinade storage compartment 60 prior to sealing the end 18. After the marinade is placed in the bag 10, the end 18 of the bag is sealed, and the bag 10 is ready to be used.
  • a rupturable seal 110 which extends from one opposed sealed side 20 to another opposed sealed side 22, is located approximately halfway between the zipper type seal 24 and the sealed end 18.
  • the rupturable seal 110 may be either straight, as shown in Figure 6, or optionally may be arcuate.
  • the rupturable seal 110, the reclosable closure 24, and the opposed sides 20 and 22 define a central storage compartment 120.
  • the rupturable seal 110, the sealed end 18, and the two opposed sides 20 and 22 define an end storage compartment 130.
  • Various foods may be stored in the central storage compartment 120 and the end storage compartment 130.
  • liquid or liquid-like food can be stored in the end storage compartment 130, and dry or moist food can be stored in the central storage compartment 120.
  • dry or moist food include uncooked dry pasta, semicooked dry pasta, semicooked moist pasta, and uncooked or semicooked rice, dry soup components solid components of potato salads or green salads.
  • liquids or liquid-like food include broth, sauce, and salad dressing. It will be appreciated by those skilled in the art that many other types of food that benefit from being stored separately may be stored in the compartments 120 and 130.
  • dry pasta may be stored in the central storage compartment 120
  • pasta sauce may be stored in the end food compartment 130.
  • the consumer opens the sealed end 16, opens the closure 24, and opens the rupturable seal 110 which separates the compartments 120 and 130, allowing the sauce to coat the pasta.
  • the user reseals the closure 24, and places the resealed bag 10 in hot water to cook the pasta and sauce. Thereafter, the user can open the closure 24 and retrieve the food.
  • the center storage compartment 120 can store food such as the salad components of potato salad while the end storage compartment 130 can store dressing for the potato salad.
  • lettuce or other salad components can be stored within the center storage compartment 120 and a dressing for the salad can be stored within the end food compartment 130.
  • moist semi-cooked pasta may be stored in the central storage compartment 120, and pasta sauce may be stored in the end storage compartment 130. The user may then heat the food within the bag by placing the bag in hot water to heat the food without opening the rupturable seal. The user may then open the closure 24 and the rupturable seal 110 to allow the heated foods to mix and to retrieve the food.
  • the sheets 12 and 14 should be high temperature materials which may be boiled or otherwise heated.
  • the bags illustrated in Figures 1-4 or Figures 6-7 can be joined at the side edges to form a multi-unit package. This allows a consumer to purchase more than one conveniently packaged marinade bag, and to use only the desired amount of marinade capacity.
  • Figures 8 and 9 illustrate an embodiment of a dual package of reclosable bags for marinating food with two bags, although it also envisioned that a package with more than two bags could be formed.
  • the package 80 includes a flexible top plastic sheet 102 and a a flexible bottom foil sheet 104 sealed to the flexible plastic sheet along the periphery of the package 80 to form opposed sealed sides 84 and 86, and opposed sealed ends 88 and 90.
  • the flexible plastic sheet 102 is joined to the flexible foil sheet 104 along a line extending from one end 88 to the other end 90, thus forming two bags 94 and 96.
  • Each bag 94, 96 has a generally rectangular shape, and opposed sealed first end 88 and second sealed end 90.
  • the first bag 94 has a sealed side edge 98 that joins the sealed side edge 100 of the second bag 96 at the joined area 92.
  • the second bag has sealed side edges 100 and 86.
  • a recloseable closure 24 joins the flexible plastic sheet and the flexible foil sheet adjacent the first end 88 of each bag.
  • the recloseable closure 24 and the first sealed end 88 of the bag define an openable region therebetween.
  • an arcuate rupturable seal 30 extends from one opposed side 84 to the other side 98 of the first bag 94 and joins the flexible plastic sheet 102 and the flexible foil sheet 104.
  • a top 32 of the arcuate rupturable seal 30 is approximately centrally located between said opposite sides 84 and 98.
  • a marinade storage compartment 60 is formed by the arcuate rupturable seal 30, the opposed sides 84, 98, and the second end 90.
  • the recloseable closure 24 with said opposed sides 84, 98 and said second end 90 form a food storage compartment 70
  • the second bag 96 also has an arcuate rupturable seal 30 which forms a marinade compartment 60 with the opposed sides 86, 100 and the sealed second end 90.
  • Perforations 106 are formed in the joined area 92 between the bags 94, 96 to facilitate separation of the bags 94, 96 by the consumer. It will be clear to one of skill in the art that in an alternative, the bags 94, 96 can also be cut apart by the consumer, and that the perforations 106 can be replaced by other structures to assist the consumer in separating the bags, for example, notches, a single large perforation, indentations, or thinner portions of the joined area 92.
  • Notches 108 located at a first sealed end 88 of the bag in the side edges 84,
  • 86 can be used by a consumer to tear the sealed end 88 from the bag, in preparation for opening the recloseable closure 24.
  • each bag 92, 94 in the dual-package 80 can be less than that of the single marinade bag 10 described above, so that each bag contains less marinade and has a smaller food capacity, suitable for use by smaller families or for individuals.
  • each bag 92, 94 could be the same size or even larger than the marinade bag 10, so that the consumer can conveniently purchase a multi-package of larger marinade bags.
  • the package 80 can be folded into thirds prior to use.
  • Other food storage bags discussed herein, such as the food storage bag of Figures 6, 7 can also be joined as side edges in a manner similar to that described above.
