The invention pertains to storage bags suitable for use in the containment and protection of food items, and more particularly storage bags used to season a food item.
The use of storage bags for containing items, such as food items, is generally known in the art. These bags are typically constructed of a film with an open mouth disposed near the upper end of the bag. Often a closure will be provided such that the open mouth may be sealed to prevent the item from exiting the bag, restrict the exposure of the item to external air exposure, and prevent contact of the food item with external contaminants.
One application of these types of storage bags is the use of the storage bag to season a food item by, for example, marinating the food item within the bag. For example, it may be desirable to marinate a piece of meat for a period of time before cooking. The meat absorbs and/or is coated with the marinade to add flavor to the meat. These types of storage bags provide an inexpensive and disposable medium for containing the food item and seasoning mixture. Typically, the marinade mixture is a liquid or solid mixture and consumers must measure and add the proper amount of seasonings to the bag. This is usually a messy, time consuming, and inconvenient endeavor. Thus, there is a need for a storage bag that makes seasoning food items in storage bags cleaner, faster, and more convenient.
The invention provides a bag for applying seasoning to a food item. The bag comprises a mouth, an interior surface, and a seasoning. The mouth receives the food item, and the seasoning is adhered to at least a portion of the interior surface such that the food item may be seasoned if placed through the mouth into the bag.
The invention further provides another bag for applying seasoning to a food item. The bag comprises a first compartment, a second compartment, and a seal. The first compartment stores the food item and has a reclosable mouth for receiving the food item. The second compartment stores the seasoning. The seal is disposed to enclose the second compartment and is releasable to permit the seasoning to enter the first compartment and season the food item.
The invention also provides a seasoning application kit for enabling a consumer to season a food item. The kit comprises a seasoning bag and a container for storing the bag prior to use. The bag comprises an interior surface having a seasoning adhered at least partially thereon and an open mouth for inserting a food item into the bag. The container has an opening for removing the bag from the container. The consumer removes the bag from the container and inserts the food item into the open mouth to season the food item.
The invention provides a storage bag 100 suitable for seasoning a food item. The seasoning bag 100 comprises a seasoning such as a marinade or curing mixture disposed within the bag 100 prior to purchase by a consumer. In this way, the seasoning is already prepared and measured in a desired quantity before a consumer opens the bag 100. Thus, a consumer saves time and avoids the hassle of preparing and measuring the seasoning. Furthermore, the seasoning bag 100 has a structure suitable to apply the seasoning in a uniform manner over the outer surface of a food item with minimal effort by the consumer.
Referring to
An upper end of the bag 100 includes a mouth 112 for insertion of articles into the interior of the bag 100. A reusable closure 114 comprising complementary mating elements 116, 118 may be located on the interior of the sidewalls 102, 104 near the mouth 112 for reclosably sealing the mouth 112 of the bag 100. For example, the reusable closure 114 may comprise an adhesive closure or an interlocking seal type closure, and may or may not include a slider for manipulating opening and closing of the bag 100. It will be appreciated, however, that any suitable closure 114 may be used.

As used herein, “adhesive” or “adhesive materials” include all materials typically considered for use to adhere one material to a target surface. Adhesive materials include, but are not limited to, glues, solvent-based adhesives, emulsions, and hot-melt pressure sensitive adhesives. An adhesive may be applied to the seasoning bag by any conventional application method known in the industry. This includes, but is not limited to, roller application, spray, coating, printing, transfer, extrusion, brush, pads, or combinations thereof.
Examples of suitable adhesives may include any cereal or root starch or flour, such as, but not limited to, maize, rice, barley, wheat, sorghum, tapioca, potato, corn starch, and the waxy versions thereof, and the corresponding flours. Converted, i.e., acid treated starches or chemically modified starches may also be used.
In some embodiments, water-soluble carbohydrates including monosaccharides, disaccharides, and trisaccharides may be used to form an adhesive and include, but are not limited to, sorbitol, mannitol, maltitol, lactitol, fructose, glucose, sucrose, corn syrups, maltodextrin, or combinations thereof. An example of a carbohydrate based adhesive is N-TACK®, a maltodextrin based product made by National Starch and Chemical.
In other embodiments, organic macromolecular adhesives may be used and include, but are not limited to, proteins, zein, casein, shellac, cellulose, gelatin amide-containing polymers, pectin, or PNVP polymers such as poly-N-vinylpyrrolidone, poly-N-vinyl-N-methylacetamide, polyacrylamide, polymethacrylamide, poly-N,N-dimethylacrylamide, poly-N, N-dimethylmethacrylamide, poly-N-vinylpiperidone, polyethyloxazoline, or combinations thereof.
Edible gums may also be used to form an adhesive and include, but are not limited to, vegetable gums, such as guar gum, carob bean gum, gum tragacanth, xanthan gum, tamarind gum, locust bean gum, arabic gum and karaya gum; marine gums, such as carrageenan and alginate; cellulose gum, such as carboxymethyl cellulose, and mixtures thereof.
In further embodiments, edible fats, or oils may also be used and include, but are not limited to, safflower oil, olive oil, cottonseed oil, rapeseed oil, corn oil, canola oil, soybean oil, palm oil, rice (bran and germ) oils, sunflower oil, sesame oil, lard, beef tallow, fish oil, butter, and mixtures thereof.
Combinations of the materials described above may be used to form an adhesive as well. An example of an adhesive composition made by combining a number of the above ingredients includes the combination of maltodextrin, whey protein concentrate, and xanthan gum, with a balance of water, which is blended until the mixture is smooth.
While specific compositions suitable as adhesives and as curing or marinating agents have been described herein, it will be appreciated that many other such compositions could be formulated within the scope of the invention. Further examples of suitable adhesives may be found in U.S. Pat. Nos. 6,623,773 and 4,501,758, which are incorporated in their entirety herein. It will be appreciated, however, that any suitable adhesive may be used, and in certain embodiments, the seasoning 120 may be capable of retaining itself to the sidewalls 102, 104 of the bag 100. In other embodiments, the seasoning may be dispensed in an uneven pattern. For example, the seasoning may be located in the area where the food will reside, such as, the center of the bag.

The bag 300 may further comprise a substrate layer 332 disposed on the outer surface of the layer comprising the susceptor material. The substrate layer 332 may be constructed of any suitable material, including but not limited to, a paper material, a woven material, a non-woven material, a foam material, or a paperboard material. The substrate layer 332 may be selectively adhered with adhesive 348 to the layer comprising the susceptor material such that one or more pockets 334 are formed between the layer comprising the susceptor material and the substrate layer 332. As shown in
In certain embodiments, it may be desirable to add a seasoning during or after the cooking process. Referring to
It will be appreciated that the seasoning bag 400 may have any suitable number of storage compartments separating any suitable number of seasonings 420. It will further be appreciated that embodiments having multiple bond lines 440 may be constructed such that the bond lines 440 release at approximately the same time or at any suitable differing times before, during, or after the cooking process. The bond line 440 may be formed of any material suitable for sealing the seasoning area 436 from the main storage area 438 such that the bond line may release before, during, and/or or after cooking to apply a seasoning 420 to a food item 426.
Referring to
It will be appreciated that any suitable vacuum device 546 may be used to remove air from the seasoning bag 500. Furthermore, any suitable type of valve may be used. Having the seasoning adhered to the sidewalls 502, 504 of the bag 500 permits the vacuum operation to take place without adversely affecting the application of the seasoning 520 to the food item 526. For example, if the seasoning 520 were not adhered to the sidewalls 502, 504, then the sucking action of the vacuum device 546 may remove substantial amounts of seasoning 520 out of the bag 500, which would waste seasoning 520 and ruin any seasoning measurements made by the consumer and uncontrollably altering the amount of seasoning applied to the food item 526. In addition, the seasoning may clog the valve. In one embodiment, the valve may include a filter to prevent clogging of the valve. By coating the bag with seasoning, the air may take a tortuous path in order to be expelled through the valve and thus the amount of moisture and liquid from the food will be reduced from exiting the valve. The seasoning on the sidewall is also a way to omit or reduce the need for an embossed bag in order to create a tortuous path to separate air from liquids so that air can be expelled through the valve.
Turning to
The seasoning may be applied to the interior of the bag via any suitable process. For example, in one embodiment, the bag may be coated with an edible adhesive and a spice duster may apply the seasoning. In another embodiment, sheets coated with a seasoning may be inserted and sealed to the interior of the bag (by laminating or spot sealing, for example). Additional examples of processes for coating a material with an adhesive and seasoning may be found in U.S. Pat. No. 6,623,773, which is incorporated in its entirety herein.
It will be appreciated that, while the seasoning bag makes the marinating process easier, cleaner, and more convenient for a consumer, the seasoning bag also permits a consumer to customize the flavor of the food item. Given that the seasoning is applied to the food item in the seasoning bag, a user can easily add additional spices, flavorings, liquids, etc. to the seasoning bag.
The seasoning bag may be any suitable size and/or shape to accommodate one or more food items for marinating. Additionally, the seasoning bag may be constructed of any suitable material and have any suitable thickness. Examples of materials that may be used for the bag include, without limitation, thermoplastic materials or a blend of thermoplastic materials. The films may be made by a conventional cast or blown film process. Useful thermoplastics include, without limitation, polyolefins such as high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), and polypropylene (PP); thermoplastic elastomers such as styrenic block copolymers, polyolefin blends, elastomeric alloys, thermoplastic polyurethanes, thermoplastic copolyesters and thermoplastic polyamides; polymers and copolymers of polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), saran polymers, ethylene vinyl acetate (EVA) copolymers, cellulose acetates, polyethylene terephthalate (PET), ionomer (Surlyn®), polystyrene, polycarbonates, styrene acrylonitrile, aromatic polyesters, linear polyesters, nylon, thermoplastic polyvinyl alcohols; foils, metalized films, wax paper or grease proof paper, nonwoven webs, fabrics, paper, ethylene copolymers, ethylene methyl acrylate (EMA) copolymer, polyethylene terephthalate glycol (PETG) copolymer, polyethylene-propylene copolymers, any suitable combinations thereof, and any other suitable materials.
It is contemplated that storage bags within the teachings of the present invention can include any number of layers and that any number of layers can be used in any of the films used to make the bags by using processes known in the art including, without limitation, co-extrusion and lamination. For example, nylon or ethylene vinyl alcohol copolymer layers can be used to improve the flavor, aroma, and oxygen barrier properties of the bags. Further, one of skill in the art will realize that individual layers, or the components comprising an individual layer, utilized for the bag of the present invention can be selected to provide a specific functional or aesthetic requirement. In a non-limiting example, a UV-resistant layer can be provided within the structure of a layer comprising the bag of the present invention to prevent the photo-degradation of a product positioned within the bag.
Although, for purposes of explanation, the bag has generally been referred to as a seasoning bag containing a seasoning, it will be appreciated that the bag may be used for marinating a food item over a period of time, and/or may contain ingredients suitable for curing a food item. Furthermore, additives may be included such as preservatives, food freshness treatments, anti-microbials, colorants, fragrances, flavors, etc. Examples of suitable seasonings include, but are not limited to, vinegar, sugar, beef base, salt, pepper, glucose solids, hydrolyzed plant protein, hydrogenated peanut oil, yeast extract, citric acid, cream of tarter, herbs, spices, dried fruit, and natural and artificial flavorings. Additional examples of seasonings are disclosed in U.S. Pat. No. 6,623,773, which is incorporated in its entirety herein. Thus, it will be appreciated that the seasoning may be any suitable seasoning for flavoring, marinating, curing and/or otherwise treating a food item.
