Definitions

  • the present invention relates to packages and structures and methods for releasing active agents in such packages. More specifically, the present invention relates to active agents, such as freshness-extension agents, odor management agents, and other functional agents, and structures and methods for releasing such active agents to extend the freshness of perishable products and manage or control the odor related to such products disposed within such packages.
  • active agents such as freshness-extension agents, odor management agents, and other functional agents
  • structures and methods for releasing such active agents to extend the freshness of perishable products and manage or control the odor related to such products disposed within such packages.
  • Reclosable packages such as food containers with fitted or hinged lids, and bags with push to close or slider fasteners, are a great convenience to suppliers and consumers of pre-packaged perishables, especially for products such as luncheon meats and cheeses where, typically, only a portion of the product is used at any given time. Reclosable packages are also especially convenient for in-home use to store leftover perishable products. A problem with these reclosable packages, however, is that they do not contain any feature that serves to extend the time period that the perishable can be stored in the package and remain fresh. Thus, the contents of the package may spoil sooner and, if so, the contents will be no longer suitable for human consumption.
  • each of the disclosed packages of the present invention has a pair of opposing body panels joined together along a pair of opposing sides and a bottom bridging the sides so as to define a mouth opposite the bottom, a reclosable fastener extending along the mouth, and an active agent.
  • the reclosable fastener includes a pair of polymeric tracks, in which each of the tracks includes a mating element and a fin portion. The mating elements are releasably engageable to each other. Each of the fin portions extends generally downwardly from the respective mating element towards the bottom of the reclosable package.
  • a reclosable package is provided with an active agent that is associated with at least one of the fin portions for communication with an interior of the package.

  • the active agent is extruded with the at least one of the fin portions.
  • the active agent can be distributed in the form of microcapsules in the at least one of the fin portions.
  • the active agent is included in an active agent layer that is attached to the at least one of the fin portions via at least one of an adhesive, a co-extrusion, a heat seal, and a weld (e.g., an ultrasonic weld).
  • the active agent is included in at least one of a coating, a patch, a pouch, and a tape, applied to the at least one of the fin portions.
  • the active agent is a freshness-extension agent that includes an isothiocyanate compound.
  • the freshness-extension agent can further include an acid and/or a fragrant.
  • a structure to selectively initiate release of the active agent is provided.
  • the active agent is released by humidity.
  • a one-time breakable element extending between the fin portions and disposed between the interior and the reclosable fastener.
  • the active agent can be disposed above and/or below the one-time breakable element.
  • a barrier layer associated with the at least one of the body panels is provided to define a barrier environment for the interior.
  • a barrier layer associated with at least one of the fin portions is provided.
  • the barrier layer is located further from the interior than an active agent layer including the active agent.
  • a diffusion layer associated with at least one of the fin portions is provided.
  • the diffusion layer is adjacent to an active agent layer including the active agent.
  • the diffusion layer is located closer to the interior than the active agent layer.
  • a reclosable package is provided with a first opposing body panel having an inner surface and an outer surface, a second opposing body panel having an inner surface and an outer surface, and a reclosable polymeric seal.
  • the first and second body panels are joined along a pair of opposing sides and a bottom bridging the sides so as to form an open mouth at one end.
  • the joined body panels form an interior space.
  • the reclosable polymeric seal extends along the one end of the respective inner surfaces of the first and second opposing body panels and includes first and second polymeric tracks.

  • the second polymeric track includes a second mating element and a second fin portion, in which the second fin portion extends generally downwardly from the second mating element towards the bottom of the package.
  • the first and second mating elements are releasably engageable to each other.
  • the first fin portion includes at least a first layer having an active agent and a second layer being a barrier layer.
  • the second fin portion includes at least a third layer having an active agent and a fourth layer being a barrier layer.
  • the present invention relates to packages, packaging materials, and other related structures with an active agent incorporated therein.
  • the invention has applications for various flexible and rigid containers and packages, such as reclosable plastic bags, waste bags and liners, rigid trash containers, air-tight containers, lunch boxes, and packaging wraps and foils commonly used for perishable packaging or perishable covering.
  • package can be understood to include any kind of package or container, such as flexible plastic bags and rigid containers, as well as foils or wraps commonly used to package or store perishable items.
  • active agent can be understood to include any agent, ingredient, or composition that provides an enhancing or beneficial effect within a package or container.
  • An active agent can include a "freshness-extension” agent for extending the freshness or shelf life of food products or other perishables stored in a package, an "odor management” agent for masking, neutralizing and/or reducing odors from the package, or another functional agent.

More specifically, each freshness-extension agent of the present invention can be used to inhibit spoilage of food products or other perishables in the package, and each odor management agent of the present invention can be used to reduce, neutralize, and/or mask odors from the package.
  • Each of the active agents of the present invention can be disposed in the environment of the package, e.g., disposed in the form of a coating, patch, pouch, or tape that is applied to a component of the package; extruded with a component of the package; sprayed, brushed, coated, laminated, or stamped onto a component of the package; impregnated into a component of the package; and/or distributed in the material of a component of the package, such as in the form of microcapsules.
  • the freshness-extension agents of the present invention can be disposed in the environment of a polymeric bag for storing perishable items.
  • the polymeric bag can be intended for consumer storage of food products (e. g. , leftover food products) or applications, such as "form, fill, and seal" food packaging operations.
  • the polymeric bags can include non-reclosable and reclosable polymeric bags.
  • Reclosable polymeric bags are typically made to be reclosable via reclosable elements or fasteners, such as resealable adhesive or cohesive seals, welds (e. g. , ultrasonic welds), mated tracks, and mated dimples.
  • the mated tracks can be opened and closed by applying finger pressure or by using an auxiliary device, such as a slider.
  • Some examples of reclosable polymeric bags include the bags disclosed in U. S. Patent Nos. 5,067, 208 and 6,147,588 and U. S. Patent Application Publication No. 2004/0066985 .
  • the freshness-extension agents of the present invention can also be disposed in the environment of a rigid package for storing perishables, such as bakery containers, deli containers, fruit containers, lunch boxes, and roaster containers.
  • containers include containers disclosed in U. S. Patent Nos. 6,042,586 , 6,257,401 , 6,349,857 , 6, 644,494 , 6,845,878 and U. S. Patent Application Publication Nos. 2004/0074902 and 2005/0000966 .
  • the odor management agents of the present invention can be used in the environment of bags and liners for collecting garbage or waste and other containers for collecting items with undesirable odors, such as laundry and diapers.
  • Such waste bags can include a tie feature that assists in closing the bag or liner securely, forming a handle for carrying the bag or liner to be disposed,and/or facilitating the opening of the bag or the liner.
  • Some examples of waste bags include the bags disclosed in U. S. Patent Application Publication No. 2003/0223657 .
  • FIG. 1a depicts a mouth portion defined by a reclosable package or bag 10 with a reclosable closure arrangement such as fastener or zipper 14.
  • the fastener or zipper 14 can be opened and closed by applying finger pressure or by using an auxiliary squeezing device, such as a slider.
  • FIGs.1b-1d depict other mouth portions defined by reclosable packages or bags with a fastener or zipper.
  • FIG. 2 shows a reclosable package 70 with the mouth portion depicted in FIG. 1b in a partially open position.
  • the mouth portion of the reclosable package 10 includes a pair of first and second opposing body or wall panels 16,18 that make up a package body 20 ( FIG. 2 ) and define an interior space 22.
  • a first track 24 Connected to the first body panel 16 is a first track 24 having a first profile 26 and a first fin portion28 extending generally downward from the first profile 26.
  • the first body panel 16 has an outer surface 16a and an inner surface 16b.
  • the first fin portion 28 has an outer surface 28a and an inner surface 28b.
  • a second track 30 having a second profile 32 and a second fin portion 34 extending generally downward from the second profile 32.
  • the second body panel 18 has an outer surface 18a and an inner surface 18b.
  • the second fin portion 34 has an outer surface 34a and an inner surface 34b.
  • the inner surface 16b is attached to the outer surface 28a.
  • the inner surface 18b is attached to the outer surface 34a.
  • the first and second profiles 26,32 are releasably engageable with each other to provide a reclosable seal to the package 10.
  • the thicknesses of the first and second fin portions 28,34 generally vary from about 5 * 10 -2 mm to about 2,5 * 10 -1 mm (2 to about 10 mils). More specifically, the thicknesses vary from about 0,1 mm to about 0,2 mm (4 to about 7 mils).
  • the reclosable packages of FIGs. 1a-1d can further include an optional auxiliary slider mechanism 36 ( FIG. 2 ) slidably mounted to the fastener 14 for movement between a closed position and an open position.
  • an optional auxiliary slider mechanism 36 FIG. 2
  • the first and second profiles 26,32 are engaged to each other while the slider mechanism 36 is in the closed position, and movement of the slider mechanism 36 from the closed position to the open position disengages the profiles 26,32 from each other.
  • the package 70 of FIG. 2 also includes end terminations 37.
  • End terminations can have various purposes such as(a) preventing or inhibiting the slider mechanism 36 from going past the ends of the fastener 14, (b) interacting with the slider 36 to give a tactile indication of being closed, (c) assisting in inhibiting or preventing leakage from the package 70, and (d) holding the first and second profiles 26,32 together and providing additional strength in resisting stresses applied to the profiles 26,32 during normal use of the package 10. Further details concerning the construction and operation of the slider mechanism 36 and the end terminations 37 can be obtained from United States Patent No. 5,067, 208 to Herrington, Jr. et al.
  • an end weld can be formed by heated bars pressed against the end of the fastener, ultrasonic welding, or other ways known in the art.
  • the reclosable packages are opened by having a consumer grip the slider mechanism 36 and move it such that the first and second profiles 26,32 of the respective first and second tracks are detached from each other.
  • the package can be resealed utilizing the fastener 14 and slider mechanism 36. Specifically, the consumer grips the slider mechanism 36 and moves it from the open position to the closed position so as to engage the complementary first and second profiles 26,32.
  • a one-time breakable element 12 not only provides a consumer with the assurance that the newly purchased package has not been opened before, but also provides a good initial seal that preserves the freshness of the food products, perishables, or other contents of the package prior to its initial opening and can inhibit or prevent the active agent from being activated by an activation-triggering condition, such as moisture. Since the reclosable closure arrangements of FIGs.1b-1d are located above the one-time breakable element, (i. e., the reclosable closure arrangement is further from the interior space), the operation of the reclosable closure arrangement is not hampered by the presence of the one-time breakable element.
  • the first fin portion 28 and the second fin portion 34 have active agents 50 and 52, respectively, associated therewith.
  • the active agents 50, 52 can be the same or can be different.
  • Each active agent 50, 52 can include a substance known to provide a desired function or effect on a package or contents thereof.
  • the active agents include freshness-extension agents, which function to extend the life or freshness of food products or other perishables disposed in the package.
  • the active agent includes an odor management agent, which functions to mask, neutralize, and/or reduce an undesirable odor or to produce an aromatic odor in the package.
  • the agent 50 is incorporated within or on the fin portion 28.
  • the agent 50 is extruded with, or impregnated within, the first fin portion 28.
  • the agent 50 can be distributed in the form of microcapsules in the material of the first fin portion 28.
  • the active agent is microencapsulated prior to being integrated into the package structure. Microencapsulation encloses the active agent within a polymeric material that can withstand heat during package processing and manufacturing, but which degrades, dissolves, or otherwise breaks open and releases the active agent upon contact with pre-determined environmental factors such as moisture.
  • the active agent can be encapsulated into microcapsules, and the microcapsules can be interspersed with the molten material of the fastener and extruded into the fastener 14 during bulk production.
  • the first fin portion 28 can be otherwise impregnated with the active agent 50. It is also contemplated that the active agent 50 can be sprayed, brushed, coated, laminated, stamped, or otherwise applied onto the first fin portion 28.
  • the active agent can be disposed in a coating, patch, pouch, or tape that is applied (e.g., via a pressure-sensitive adhesive) to the first fin portion 28 after production of fastener 14.
  • the selection of a coating, patch, pouch, or tape is often dependent on the type of active agent being used. For example, an active agent in a powder form (e.g., minerals containing chemistry) can be placed in an air-permeable pouch rather than a patch because it is often difficult to embed powders in a patch.
  • an active agent in a powder form can be dusted onto a component of the package, e.g., a fin or a body panel.
  • a component of the package e.g., a fin or a body panel.
  • powdery active agents that can be incorporated into the agent-containing structure include perlite, calcium carbonate, kaolin, and ASEPTROL® antimicrobial manufactured by Engelhard.
  • the tape or patch can include an adhesive, a patch-like component, and/or a release system such as a slip additive which assists in inhibiting or preventing the agent structure from sticking to the adhesive.
  • the release system can be located on a surface of the tape or patch that is located distally from the surface that contacts the body panel to which the tape or patch is to be attached, so that sticking is inhibited or prevented when the package is wound into a roll. Materials such as siloxane and glycerol monostearate can be among the components of such a release system.
  • An agent structure can vary in size and is dependent on factors such as the desired amount of the agent, the particular agent being used, the number of agent structures being used in the package, and the size of the package.
  • the package may include two or more active agent structures.
  • the agent structures of the present invention can be attached to a package such as a reclosable bag by a pressure-sensitive self-adhesive.
  • the pressure-sensitive self-adhesive can be any suitable adhesive that attaches the agent structure to the reclosable package.
  • Non-limiting examples of pressure-sensitive adhesives that can be used include acrylic or rubber-based adhesives.
  • the agent structure being a tape or pouch can be roll fed onto a layer(s) of the reclosable package.
  • the roll-fed structure being a tape or pouch can also initially include a release liner that assists in preventing or inhibiting the agent from sticking to itself before delivery to the reclosable package.
  • the release liner if used, is separated from the roll-fed tape or pouch before the tape or pouch is attached to the reclosable package or bag. Examples of release liners include silicon-coated paper. Release liners, however, may be undesirable because of the additional cost associated therewith. It is contemplated that the agent structure can be roll fed without the use of a release liner before being attached to the reclosable package or bag.
  • the agent being a patch or pouch can be magazine fed during attachment to the reclosable package.
  • the patch is preferably magazine fed, while the pouch can be magazine or roll fed.
  • the tape is preferably roll fed during attachment to the reclosable package.
  • the tape can be unwound, cut to length and attached to the reclosable package.
  • the agent structure patch, tape, or pouch can be heat sealed directly to the reclosable package or bag.
  • the structure can be roll fed or magazine fed before being heat sealed to the reclosable package.
  • a release liner would not likely be used because the agent structure without any adhesive should not stick to itself and the release liner adds an unnecessary cost.
  • the agent structure can be attached to the reclosable package at several locations.
  • the agent structure can be attached to the body panels during the formation of the heat seals. For example, the agent structure may be located between a side seal formed between the first and second body panels. It is contemplated that other attaching methods can be used.
  • a barrier layer can be added to assist in keeping the agent in communication with the interior of the reclosable package and, thus, assist in preventing or inhibiting the freshness-extension agent from permeating through the body panel.
  • information can be printed on the agent structure such as on the barrier layer. It is contemplated that the printing can occur on different locations of the structure. For enhanced visibility and readability of the printing, it may be desirable to print on the surface of the agent structure that is closest to the body panel when the structure is located in the interior of the reclosable package.
  • the agent structure being a coating, patch, pouch, tape in one embodiment is located in the interior of the reclosable package.
  • the agent structure being a coating, patch, pouch, tape can be located on an exterior surface of the package or within layers of the package such that the agent is able to permeate into or communicate with the interior of the package.
  • the agent structure being a coating, patch, pouch, or tape can be located on an exterior surface of a reclosable package in which a portion of the body panel is removed such that the agent contained in the structure can permeate into the interior of the reclosable package. It is contemplated that a layer of a reclosable package can be permeable to the agent such that the agent is in communication with the interior of the reclosable package.
  • the active agent 52 can be incorporated or impregnated into or extruded with the second fin portion 34. It is also contemplated that the active agent 52 can be sprayed, brushed, coated, laminated, stamped, or otherwise applied onto the second fin portion 34.
  • the active agents 50, 52 include one or more freshness-extension agents.
  • Each of the freshness-extension agents can be, for example, a natural oil, an anti-microbial, an acid, or another substance that can extend the freshness or shelf life of food products or perishables.
  • freshness-extension ingredients include isothiocyanate such as allyl isothiocyanate (AIT) from natural sources, d-limonene, eugenol, allicin, isothymol, thymol, chlorine dioxide, hydrogen peroxide, sodium percarbonate, ascorbic acid, citric acid, cinnamic aldehyde, mustard, cinnamon, peppermint, spearmint, triclosan, Chinese chive (Allium tuberosum), cinnamon (Cinnarnomum cassia), corni fructus (Comus officinalis), allyl cyanide, 1-cyano-2,3-epithiopropane, allyl thiocyanate, Lactobacillus reuteri, methyl isothiocyanate, cinnamon bark oil, lemon grass oil, thyme oil, methyl jasmonate, tea tree oil, ethyl alcohol, Salicylaldehyde, carvacrol,
  • AIT allyl iso
  • AIT which can be naturally obtained from plants or foods such as mustard and wasabi, is particularly advantageous as a freshness-extension agent because of its anti-microbial properties.
  • the AIT is produced from plants such as mustard, which contains glucosinolate and myrosinase enzyme. Myrosinase and glucosinolate react with each other to produce AIT and, because the reaction involves hydrolysis, humidity activates AIT production.
  • AIT has been shown to exhibit anti-bacterial and anti-microbial properties. Because AIT is released in a gaseous form, AIT can permeate an interior of a package so as to inhibit bacterial growth therein and thereby extend food product or perishable freshness.
  • AIT-producing products including wasabi, horseradish and mustard in various forms, such as extract, powder, oil, or ground seed, can be used as the freshness-extension agent in embodiments of the present invention.
  • an AIT-containing freshness-extension agent can also be used in combination with another functional agent.
  • AIT is combined with an acid, which greatly enhances the production of AIT from mustard and, thus, the anti-microbial effect of mustard.
  • an anhydrous acid such as anhydrous citric acid for increased AIT production and enhanced freshness-extension function.
  • the freshness-extension agent can also provide other functions, and can therefore be used for such other purposes.
  • the freshness-extension agent can include a freshness component for extending food freshness and an odor component for masking, reducing, and/or neutralizing only a pungent odor of the freshness component, but not other odors of the contents stored in a package.
  • the odor component does not mask the odors of the contents stored in the package, such as food odors or food spoilage odors, so that decay or spoilage of the contents can be detected by scent.
  • a freshness-extension agent including an AIT freshness component can also include a fragrant component, such as vanilla, cinnamon, or citrus oil, which can mask the pungent odor of AIT, but not mask or otherwise affect the odor of the stored contents.
  • a fragrant component such as vanilla, cinnamon, or citrus oil
  • the freshness-extension agent does not impart its own organoleptic properties to the stored contents, and thus permits a user to readily detect decay or spoilage of stored contents by smell.
  • the active agents 50, 52 include one or more odor management agents.
  • the odor management agent can be incorporated into packages configured for collecting garbage or waste to mask, neutralize, and/or reduce undesirable odors.
  • the odor management agent can be used to provide or create an odor to a package.
  • An odor management agent can thus be incorporated into thermoplastic bags or liners and other containers, such as garbage or waste bags, diaper containers, laundry bags, storage bags, and disposable medical bags or containers.
  • Non-limiting examples of odor management agents include AIT, d-limonene, mustard, natural oils, chlorine dioxide, hydrogen sulfide, methyl mercaptan, ammonia, citronella, pine, flowery, and substituted esters such as METAZENE®.
  • a preferred embodiment of an odor management agent includes AIT, which agent can be provided by incorporating, for example, mustard in the active agent.
  • mustard whether in the form of ground mustard seed, powder, oil, or paste, can be provided alone or in combination with an acid (such as citric acid) to catalyze the production of AIT from mustard and enhance the anti-microbial and odor management properties of the mustard.
  • an acid such as citric acid
  • AIT can provide multiple functions when incorporated into a perishable package, e.g., AIT can perform both freshness-extension and odor- management functions.
  • the odor management agent can include an additional ingredient for providing a pleasant or desired odor or scent to a user.
  • a natural oil such as lemon grass oil can be used to manage odors emanating from a package, to mask the odor of the primary odor management agent itself, or to make the odor of the odor management more pleasant to a user. It has been shown that a composition comprising ground mustard seed and anhydrous citric acid mixed with about 5% by weight of lemon grass oil is particularly effective at managing unpleasant odors.
  • an active agent 50, 52 includes an aromatic or perfumery ingredient for providing a desired scent to a package
  • an additional material for enhancing scent concentration in the interior of the package can be included.
  • the active agent 50 can include perlite to increase the scent concentration.
  • Perlite is desirable for use because of its ability to retain scent, its stability, and its surface area.
  • Non-limiting examples of other materials for enhancing scent include microspheres, talc, silicon, silicate such as aluminum silicate, vermiculite, diatomaceous earth, or combinations thereof.
  • the first and second fin portions containing at least one active agent include activation systems that are triggered when the reclosable package is opened or filled with content.
  • the activation systems can be mechanical in nature, such as a perforation or a peel-apart system that once separated initiates the release of the active agent.
  • Another activation method can be based on the humidity or moisture level present in the package (which correlates to water activity of the contents). For example, a high amount of humidity can initiate a chemical reaction that subsequently releases a volatile chemical such as carbon dioxide or chlorine dioxide. In such an example, a greater amount of active agent is added when the humidity is higher in the reclosable package.
  • reactions that are activated by a high humidity level are salt and acid reactions, such as sodium bicarbonate and citric acid, or sodium hypochloride and citric acid reactions.
  • the release of AIT is also aided by humidity as previously explained. In such examples, a greater amount of active agent is released into the package atmosphere when the humidity increases.
  • a reclosable package with a humidity-activated freshness extension agent for example, perishables are placed in the interior of the package, and the humidity or moisture level in the perishables activates the freshness-extension agent. Additionally, if the agent is disposed proximate the mouth of a bag-like package or proximate the rim of a container-like package, selective activation or release can be accomplished.
  • the humidity or moisture level of the perishables can activate the agent as the perishables travel in the vicinity of the agent (e.g., through the mouth or past the rim of the package during the initial placement of the perishable products into the interior), while the perishable products remain disposed in the interior, and upon entry of air into the interior (e.g., during an opening of the package).
  • Disposing the agent proximate the mouth or rim of a package can also be advantageous when maximum display of the contents is desired in a transparent package.
  • a humidity activation method can further be controlled by providing a barrier layer material.
  • the body panels provide a barrier layer or be formed of a barrier material so as to create an enclosed environment to prevent or inhibit the introduction of humidity and the release of active agent when the package is closed.
  • the fin portions can provide a barrier layer or be formed of a barrier material.
