A reclosable, multi-compartment package and, in particular, a dual compartment package with frangible seals separating the package into at least two compartments for separately storing different moisture level foodstuffs and methods of manufacture thereof.
Consumers often desire simplified solutions for cooking meals. One meal solution is to coat a food item in a breadcrumb coating, for example, and/or to marinade the food item before cooking. This preparation method allows the consumer to coat or marinade the food item and then, for instance, to place it in the oven to bake. The preparation time required on the part of the consumer includes the initial preparation of ingredients and then the few minutes it may take to coat the food item, or initially place the food item in the marinade. When the consumer chooses to coat or marinate the food item more than one foodstuff may be used, such as breadcrumbs mixed together with cheese. In order to make a multi-foodstuff coating for the food item, multiple foodstuffs may have to be separately obtained and mixed together in a common container or bowl, such as buying separate cheese and separate breadcrumb ingredients and then mixing the two together in a bowl. The consumer would then place the food item to be coated in the container containing the mixture of the different foodstuffs.
An alternative method to coating a food item in this manner is to purchase an already-prepared coating or marinade that may combine multiple ingredients. However, due to different moisture levels between foodstuffs, such as cheese and breadcrumbs, these ingredients may be required to be sold and packaged separately so that the cheese does not lose moisture to the breadcrumbs making the breadcrumbs soggy and the cheese dry.
There are a variety of other types of food packages being used today for other varieties of foods. For example, there are multi-compartment bags or packages currently being used on the market; however, many of these packages are manufactured for the purpose of separating a package into multiple compartments with the seal separating such compartments being a permanent seal. Thus, if this type of package were used to separate the different moisture level foodstuffs needed in a food coating or marinade, the foodstuffs would still need to be removed from this package and placed into a different package or a separate container to mix the ingredients together before coating the food item since the seal separating the compartments is permanent, such as the package disclosed in U.S. Patent Application No. 2002/0067865. Often, these multi-compartment packages often do not have a reclosable feature and some may even require cutting the package to open it, such as is disclosed in U.S. Pat. No. 3,074,544.
Still other types of packages having multiple compartments may provide a temporary seal between the two or more compartments, however, the temporary seal may require an involved, and often difficult, separation technique. For example, one such package (U.S. Pat. No. 3,608,709) discloses applying a pressure to the outside of the package, such as to a liquid ingredient in one compartment, to rupture or burst the temporary seal in order to separate the seal and combine the compartments it separates. If too little pressure is applied, the seal will not burst; if too much pressure is applied the package itself may burst apart and spill the contents of the package.
Another type of non-reclosable package with one or two temporary divider seals (U.S. Pat. No. 3,156,352) contains outer tabs for use in separating the heat seals. Through the use of pulls tabs, the divider seals are disrupted by a stripping away action instead of applying shear forces.
Many multi-compartment packages typically aren't reclosable. One such non-reclosable package is disclosed in U.S. Pat. No. 4,145,449, where a two-compartment package is used to separate an ice cream block and a wafer used to make an ice cream sandwich. The top seal and middle seal are both temporary seals, and the bottom seal can also be a temporary seal, such that the package can be openable from either end. There is no opening mechanism to aid in separating the temporary seals. Opening the top seal (or bottom seal) can prove to be difficult, because the consumer must first try to separate the layers and then use the separated edge as a grasping point for pulling apart.
U.S. Pat. No. 6,743,451 discloses a package having a central compartment and a marinade storage compartment is disclosed. The marinade storage compartment may contain a marinade to which a food can be added. One end of the package contains a sealed end and a reclosable closure. Dividing the central compartment from the marinade storage compartment is a rupturable seal, such that the central compartment is bound by the rupturable seal at one end and the reclosable closure at an opposite end. The marinade storage compartment is bound by the rupturable seal at one end and a sealed end opposite the rupturable seal. To gain access to the package interior, a tearable end to the package is provided which is opened to provide access to the reclosable closure. Once the reclosable closure is also opened, the rupturable seal can be separated to gain access to the marinade storage compartment. Once opened, the food product can be placed in the marinade and the package reclosed. The configuration of the compartments in this fashion can make opening the package difficult when there is food in each compartment. Once the reclosable closure is opened, only the central compartment is accessible, exposing the food product therein. The rupturable seal must be opened next to gain access to the second food product in the marinade storage compartment in order to co-mingle the two food products.
A reclosable, multi-compartment package is provided having a frangible peel seal arrangement that separates a pair of food compartments to create a hermetically sealed package prior to use consisting of a convenient package system that reduces the amount of steps and time required to prepare a meal, separately stores foods having different moisture levels, and provides for mixing of the separated foods upon opening of the package. Purchasing a single package with all of the coating or marinade ingredients in that package and providing for mixing of these ingredients in the same package can be more convenient than purchasing all of the ingredients separately and then having to combine them in a different container. The package after opening can be used as the coating or marinade container thus making the meal preparation fast and easier compared to typical methods. Furthermore, using the packaging to mix the components therein and to coat the food product can create less mess and may be easier to clean up.
The multi-compartment package with hermetic inner peelable seals can have a slider zipper reclose covered by a shroud separable along a tear line. The separate compartments of the package can store different moisture level foods, such as a farinaceous foodstuff in one compartment and a dairy foodstuff in another compartment, until the package is opened. The separation of the different moisture level foods in individual compartments can keep each respective foodstuff in a fresher state than if combined. For example, a farinaceous foodstuff can comprise a breadcrumb mixture and a dairy foodstuff may comprise cheese. If cheese and breadcrumbs are mixed together in a common compartment, over time, the cheese may lose its moisture to the breadcrumbs thus causing the cheese to dry out and the breadcrumbs to absorb moisture and become soggy.
The inner peelable seals pull apart easily as the consumer opens the top of the package, facilitating mixing of the components. As the top of the package is opened, the inner peel seals can be peeled apart to combine the multiple compartments into one. The peel seals are configured such that a transverse seal runs along the opening of each compartment and at least one divider seal intersects the transverse seal and separates the inner product-receiving cavity of the package into one or more compartments; thus both compartments are bound in part by the peelable seals.
In one example, breadcrumbs and cheese can be kept separate until time of use. When mixed together they can form a crispy and cheesy coating for meat, fish, vegetable, and/or poultry products. The package can be used as the “shaking bag” where a consumer can remove the shroud along the tear line, shift the slider to open the zipper, and pull apart the transverse peelable seal disposed inwardly from the zipper and peeling the divider seal that separates the at least two food components. The consumer can then reclose the package using the slider/zipper and shake the food components together until sufficiently mixed in the newly formed unitary compartment. The consumer could then re-open the package and place one or more pieces of meat or the like herein, close the package using the slider/zipper and shake until the meat is sufficiently coated. The consumer could then re-open the package, take-out the coated meat and proceed to cook it. This process can then be repeated until the food components are used up or all of the meat pieces are coated.
A reclosable, multi-compartment package and, in particular, a dual compartment package with frangible seals separating the package into two compartments for storing different moisture level foodstuffs until opening the package, and methods of manufacture thereof, are disclosed herein and in
In particular, the reclosable, dual-compartment package comprises opposing walls with seals at first edge portions, second edge portions, and side edge portions. A removable shroud portion includes the seal at the first edge portions of the opposing walls and can be removed along a weakness formed in the opposing walls for a more controlled tear and to allow access to a reclosable zipper. The reclosable zipper can be opened to allow access to a frangible transverse seal which bounds a mouth portion, or opening, of each of the two compartments and can be opened to gain access to each of the compartments. Each of the compartments is further divided by a frangible divider seal which can also be opened to permit combination of the foodstuffs in each of the compartments.
A reclosable, dual compartment package 10 is shown in
The frangible seals 16 and 18 define the two compartments 42 and 44 of the package 10 used for separating foodstuffs, and typically for separating foodstuffs having different moisture level requirements until the package 10 is to be opened. The package 10 has a frangible transverse seal 18 and a frangible divider seal 16, generally perpendicular to the transverse seal 18. The frangible transverse seal 18 is parallel to the seal at the first edge portions 23 of the package 10, or the first seal 22, and extends between the seal at the side edge portions 25, or the side seals 24, as further illustrated in
The frangible divider seal 16 extends between the transverse seal 18 and the second seal 20 of the package 10. The frangible divider seal 16 is generally parallel to the side edge portions 25 such that it is also generally perpendicular to the second seal 20 and the frangible transverse seal 18, and can be located equidistantly between the opposing side seals 24 or the frangible divider seal 16 can be located closer to one side seal 24 than to the other side seal 24 to vary the relative sizes of the compartments 42 and 44.
The frangible divider seal 16 can terminate at a lower end 15 intersecting the second seal 20 and can terminate at an upper end 17 intersecting the frangible transverse seal 18, as shown in
The frangible divider seal 16 divides the main receiving cavity 46 of the package 10 into at least two compartments 42 and 44 for separating foodstuffs with different moisture levels and therefore different storage requirements. One configuration of the package 10 may contain breadcrumbs in one compartment 42 and cheese in the other compartment 44. If the two differing foodstuffs were stored together in the same compartment, such as breadcrumbs and cheese, the breadcrumbs may absorb some moisture from the cheese and begin to lose their crispness and the cheese could begin to dry out and become hard. Therefore, as a result of the different storage requirements between the two foodstuffs, each is better stored separately to maintain food properties. However, when the package 10 is opened, the separated ingredients can then be combined into one mixture in order to coat a food item 48 with the mixture; therefore the frangible seals 16 and 18 are able to be peeled apart to form a common main compartment 46. Alternatively, foodstuffs that may not have differing moisture levels and may not require separate storage compartments can nevertheless also be stored separately.
The frangible transverse seal 18 is separated to gain access to each of the two compartments 42 and 44, and can be used to form a hermetic cavity with the side seals 24 and second seals 22. The frangible transverse seal 18 can bound the open end of each compartment 42 and 44, such that when the frangible transverse seal 18 is opened and separated, it provides access to both compartments 42 and 44; alternatively, the transverse seal 18 does not have to border each compartment. The frangible divider seal 16 can either be opened at the same time as the opening of the frangible transverse seal 18, can start opening at the same time and finish after the frangible transverse seal 18 is opened, or can start opening after the frangible transverse seal 18 has been opened. As the frangible divider seal 16 is separated, it removes the division between the two compartments 42 and 44, thus combining the two compartments 42 and 44 into the main compartment 46, as shown in
A peel strength of the frangible seals, or a force to peel the seals apart, can also be measured to determine how much force is needed to peel apart the opposing walls 12 and 14 of the frangible seals 16 and 18, which can be affected by various sealing bar parameters. Four parameters that may affect the peel strength of the frangible seals 16 and 18 can be the seal time, the pressure, the temperature, and a pattern that may be on the surface of the sealing bars. These four parameters at a minimum can be varied to obtain the desired opening conditions of the seals 16 and 18. For example, a preferred average sealing temperature range for a single hit, or single application, of a heat source to create the frangible seals 16 and 18 can typically be from about 275° F. to about 350° F., with a sealing time of about 0.1 seconds to about 1 second on a high speed process line, and preferably a sealing time of about 0.35 seconds. The frangible seals 16 and 18 can have peel strengths ranging from about 200 grams to about 400 grams, for example, as compared to peel strengths of greater than about 1000 grams for the outer perimeter seals (i.e., side seals 24, first seals 22, and second seals 20). Additionally, the peel strength to initiate the opening of the seal is typically greater than the force needed to continue opening the seal. Typically, for a frangible seal to peel easily apart, a lower sealing bar pressure and lower temperature at a short seal time is desired when high process line speeds are used.
The reclosable, multi-compartment package, as shown in
The frangible seals 16 and 18 typically are made with a single hit (one application of a heat source), such that these seals can be peeled apart easier than the outer seals. The frangible transverse seal 18 can intersect the side seals 24, extending between the side seals 24, and is generally parallel to the first seal 22. As stated previously, the frangible transverse seal 18 can have at least one undulating edge, such that one side of the seal has a propagating edge that extends between the side seals 24 of the package 10. The undulating edge along the frangible transverse seal 18 can help to initiate the opening of the seal 18, and requires less force to open than a straight edge.
The frangible divider seal 16 located between the opposing walls 12 and 14 can extend between the frangible transverse seal 18 and the second seal 20 to subdivide the product-receiving cavity into two compartments 42 and 44. Alternatively, the frangible divider seal 116 can extend from the frangible transverse seal 18 towards the gusset feature 120, but terminates at an intersection with one of the side seals 124, such that the frangible divider seal 116 has an arcuate shape, as shown in
Positioned between the first seal 22 and the frangible transverse seal 18 is a reclosable structure, such as a zipper segment 26 attached to the opposing walls 12 and 14 along two zipper flanges 40. The zipper flanges 40 are attached to the opposing walls 12 and 14 at a flange seal 32 positioned between the second seal 20 and a weakness 30 formed in each of the opposing walls 12 and 14, and more specifically, the zipper flanges 40 may be attached to the opposing walls 12 and 14 at a position between the weakness 30 and the frangible transverse seal 18, such that the flange seal 32 is parallel to the first seal 22. Alternatively, the frangible transverse seal 18 can be formed between the zipper flanges 40 wherein the zipper flanges 40 are joined together at the frangible seal 18. Furthermore, the frangible transverse seal 18 can be a weakness formed in one of the zipper flanges 40 or between the zipper flanges 40.
The reclosable zipper can also include two mating portions that make up the reclosable zipper segment 26, where each is attached to an end of the zipper flange 40 that is not attached to the opposing walls 12 and 14 of the package 10, which provides the zipper segment 26 on which the slider 28 can slide along. Also along the zipper segment 26 and at each end is a stopper section 36 that terminates at an intersection with the side seals 24, to prevent the slider 28 from being adjusted past the stopper section 36 and to prevent sliding off of the zipper segment 26. Alternatively, the reclosable structure can be an adhesive reclose feature such that one or both of the opposing walls of film can contain a self-tacking film or adhesive which sticks together and keeps the opposing walls closed after opening. One example can be where the adhesive reclose feature is positioned on the outside of an opposing wall of the package and the other opposing wall forming a flap which can cover the package opening and adhere to the adhesive on the outside of the package to close the opening. Still alternatively, the reclosable structure can be a zipper without a slider.
Located adjacent the zipper segment 26 is a weakness 30 formed in each of the opposing walls 12 and 14, intersecting the side seals 24 and generally parallel to the zipper segment 26. The weakness 30 acts as a tear line along which a removable shroud portion 38 is separable. The weakness 30, or tear line 30, may be generally linear, as illustrated in
When the package 10 is to be opened, as shown in
The removable shroud 38 also includes the first seal 22, and a portion of a window segment 34. The window segment 34 provides a small gap or opening through which the slider 28 is visible when the package 10 is in the closed, unopened state. The window segment 34 can alternatively be a clear or transparent window in the film in the area of the slider 28.
The majority of the removable shroud 38 tears just below the zipper segment 26, (where the majority of the tear line 30 is positioned) thus exposing the zipper-segment 26 and the slider 28. Once the removable shroud 38 is removed, the slider 28 can be freely shifted along the zipper segment 26 between a closed position and an opened position.
After the slider 28 is adjusted along the zipper segment 26 to the open position, the consumer can continue opening the package 10 by applying a force to the opposing walls 12 and 14, in generally opposite directions, as designated by the arrows X and Y in
The foodstuff contained in the package 10 can comprise ingredients typically used to coat or marinade a meat, seafood, or vegetable product. Such food items to be coated or marinated can comprise chicken, pork, beef, fish, potatoes, as well as any other food item typically coated and then cooked. The foodstuff used as a coating typically may comprise a farinaceous foodstuff in one compartment and a dairy foodstuff in the other compartment, however, any other types of foodstuff can be separated. Dairy foodstuff ingredients that may be used can comprise any one or combination of cheeses such as Cheddar, mozzarella, Parmesan, Monterey jack, Colby, provolone, Romano, Feta, blue, American, processed and other similar ingredients, as well as other dairy ingredients such as sour cream, cream cheese, diary-based sauces, and other similar ingredients. Farinaceous foodstuff ingredients may comprise breadcrumbs, taco seasoning, bacon bits, tortilla strips or chips, and other similar ingredients. The food item to be coated is obtained and set aside in a state ready for coating, followed by baking.
The reclosable, dual-compartment package 10 is obtained having the desired coating components, such as cheese in one compartment and breadcrumbs in the other. The package 10 is opened, first by removing the removable shroud 38 and then by sliding the slider 28 along the zipper segment 26 to the opposite end of the zipper segment 26. Once the zipper portion is open, the consumer can gain access to the inner frangible transverse seal 18 and the frangible divider seal 16. Once both frangible seals 16 and 18 have been separated, the two compartments 42 and 44 are no longer divided and the previously-separated food ingredients, such as cheese and breadcrumbs, can now be mixed together in the main compartment 46. Optionally, the consumer can reclose the package 10 by sliding the zipper 28 back to the opposite side of the package 10 to the closed position and can then shake the package 10 in order to more thoroughly mix the contents. Once the food ingredients are mixed, the package 10 can be reopened (if it was previously closed), and the food item 48 to be coated is inserted into the package 10, such as a chicken leg. The package 10 is again reclosed by sliding the zipper 28 to the closed position, as shown in
Alternatively, the dual-compartments 42 and 44 can separate a sauce and a carbohydrate food item, such as a pasta, where the two can be mixed together upon opening both of the frangible seals 16 and 18 and then consumed, or still alternatively, the separate food ingredients can be combined and then added to another food item or items where the combination of the entire package and food item are cooked together. One such example can be a sauce and a cheese or dairy ingredient that is combined and added to chicken or beef in a casserole type dish and then cooked in the oven. Furthermore, the package can have multiple frangible divider seals 16 creating multiple compartments within the package 10. Other possible food products that can be stored in the package 10 can comprise salad component or toppings, omelette components added to eggs, eggs, rice, vegetables, high pressure process vegetables, dried vegetables, chunky sauces (i.e., with tomato pieces, meat, or vegetables), smooth sauces (i.e., without tomato pieces, meat, or vegetables), dry rubs, beans, potatoes, meat, and desserts, by way of example.
The reclosable, dual-compartment package can have an increased product-receiving cavity size by adding a gusset feature 120 to the package 100, as shown in
The gusset package 100, for instance, may contain a cheese product in a first compartment 144, which is bound by a portion of one of the side seals 124, a portion of the frangible transverse seal 18, and the frangible divider seal 116. The second compartment 142 may contain a breadcrumb mixture, which is bound by a portion of one of the side seals 124 and the entire edge of the opposite side seal 124, a portion of the frangible transverse seal 18, the frangible divider seal 116, and the gusset portion 120. When the package 100 is opened along the frangible transverse seal 18, access is gained to both of the compartments 142 and 144, and when the frangible divider seal 116 is opened, the two compartments 142 and 144 are combined into one main compartment and the two foodstuffs previously kept separate are then mixed together. Alternatively, the gusset feature may be positioned along one or more side edge portions rather than the bottom edge (i.e. second edge portion) and, therefore, the frangible divider seal may still extend between the frangible transverse seal and the second edge or bottom of the package, as described in relation to
Alternatively, the frangible divider seal could remain the same as in the standard, gusset-less package 10, where the divider seal 161 would be perpendicular to the second edge 21 or, in this case, the gusset feature 120, as illustrated in
Another aspect of a gusset package 300 may include two frangible transverse seals 18 and 318 with a frangible divider seal 316 perpendicular to both and extending therebetween, as shown in
Another embodiment of the reclosable package 400 is shown in
Another embodiment of the reclosable package 500 is shown in
Yet another embodiment of the reclosable package 600 can contain a transverse seal 618 positioned between the zipper flanges 40 and opposite the zipper flange seals 32, as shown in
The types of films used to create the packages 10, 100, 200, 300, 400, 500, and 600 can be any type that is typically used in the field, such as including a delamination peelable sealant or a surface peelable sealant. The frangible divider seal 16 may have an upper end 17 that has a reduced width as compared to the lower end 15. For example, the upper end portion 17 that intersects the frangible transverse seal 18 may terminate in a rounded tip end, as shown in
A variety of methods for manufacturing the package 10 described herein can be utilized. For example, the reclosable, dual-compartment package 10 can be made using the apparatus and process 200 diagrammed in
Next, the web 202 is advanced to a pair of horizontal sealing bars 210 which cooperate to seal a pair of zipper flanges 40, provided by the zipper supply roll 204, to the web 202 forming a zipper flange seal 32. The sealing bars 210 are pressed against the web material 202 in the direction of arrows A and B, and once the zipper flange seal 32 is formed, they retract in the opposite direction. This sealing is repeated as the web 202 is advanced still further in a longitudinal direction to form another zipper flange seal 32. The sealing bars 210 continually form zipper flange seals 32 along the web, such that there is a series of zipper flange seals 32 designating numerous packages all serially formed along the web and connected to one another.
Optionally, a top or first seal can be formed in the shroud by a pair of horizontal sealing bars 211, which can form a seal in the fold of the web. Alternatively, if the web material was not folded then the horizontal sealing bars 211 can create an initial seal at the first edge portion. The sealing bars 211 are pressed against the web material 202 in the direction of arrows A′ and B′, and once the top seal is formed, they retract in the opposite direction.
The frangible transverse seal 18 adjacent to the zipper is formed by a pair of horizontal sealing bars 212. The sealing bars 212 are pressed against the web, as designated by arrows C and D, and retract from the web in the opposite direction. The horizontal sealing bars 212 are generally rectangular in shape, however, one edge of the sealing bars 212 can have an undulating edge that can be similar to the desired undulating pattern for the frangible transverse seal 18.
After the frangible transverse seal 18 is formed, then the web 202 goes through a vertical sealing station which can consist of three pairs of vertical sealing bars. The first pair of sealing bars is used to form the side seals 24 utilizing vertical sealing bars 214, which cooperate to form the side seals 24. The sealing bars 214 are pressed against the web, as designated by arrows E and F, and retract from the web in the opposite direction. The sealing bars 214 continually form side seals along the web, such that there is a series of side seals 24 designating numerous packages all serially formed along the web and connected to one another.
After the side seals 24 are formed, the frangible divider seal 16 is formed by using a second pair of vertical sealing bars 216, however, the second vertical sealing bars 216 are not as long as the first vertical sealing bars 214. The second vertical sealing bars 216 used to create the frangible divider seal 16 can be shorter than the enter height of the package 10. Furthermore, the vertical sealing bars 216 can have a generally rectangular shape with a curved end. Alternatively, one end of the vertical sealing bars 216 can have a triangular end, or any other shape that gives it a reduced width than the remainder of the sealing bar width. The sealing bars 216 are pressed against the web, as designated by arrows G and H, and retract from the web in the opposite direction. In an alternate process step, all of the frangible seals, i.e., the frangible transverse seal 18 and the frangible divider seal 16, may be formed in one step utilizing a single sealing bar, for example such as a sealing bar in the shape of a ‘T’, which creates both of the frangible seals 16 and 18 simultaneously.
After the frangible divider seal 16 is formed, the side seals 24 may optionally be sealed one more time utilizing a third pair of vertical sealing bars 218. The third vertical sealing bars 218 seal the same area as the first vertical sealing bars 214 in order to increase the seal strength of the side seals 24. The sealing bars 218 are pressed against the web at generally the same location as the initial seal 24 was made by the first vertical sealing bars 214, as designated by arrows I and J, and retract from the web in the opposite direction. After the second application of sealing bars 218 to the side seal region 24, each side seal 24 then may optionally go through a cooling process, by application of a pair of cooling bars 220. The cooling bars 220 are applied in approximately the same location as the side seals 24 and the direction of the application is designated by arrows K and L, and retracted from the web in the opposite direction. Optionally, a peg-hole can be punched on the leading edge side seal 24. The final step is to singulate the packages 10 from the remainder of the web 202, such as with a blade 222. Then each package 10 can be separated from the adjacent package 10 along the web and transferred to the next section of the machine for filling. Alternatively, all of the package seals may be formed simultaneously in a single process step, or other variations thereof.
A variety of methods for filling the package 10 described herein can be utilized. For example, after the packages are singulated, they can be transferred to be filled and to receive the final seal 20 using the apparatus and process 300, diagrammed in
At an eighth station, the second seal 20 can optionally go through a cooling process, by application of a pair of cooling bars 312, which are applied in approximately the same location as the second seals 20, as designated by arrows Q and R, and retract from the web in the opposite direction. After the cooling process is completed, the package 10 is dropped into a discharge chute, where the packaging and filling process is concluded.
Furthermore, the application steps completed at stations 1-8 may be performed in a non-linear process, such as on a “rotary turret” of machinery manufactured by Laudenberg Verpackungsmaschinen GmbH, in Wipperfürth, Germany. The rotary turret can have eight stations built into it which can correspond to the same eight stations just described above. Additionally, the depths of the package compartments can be varied according to packaging preferences, and the process line drawings are not drawn to scale and do not necessarily represent actual package dimensions and ratios.
From the foregoing, it will be appreciated a reclosable, multi-compartment package is provided that allows for packaging different food components separately and methods of use and manufacture thereof. However, the disclosure is not limited to the aspects and embodiments described hereinabove, or to any particular embodiments.
