Description
- The present invention relates generally to the packaging industry. More particularly, the present invention relates to reclosable polymeric packages having a tamper evident feature.
- Reclosable packages or bags are very common, especially in the food industry. Reclosable packages are typically formed by the use of opposing body panels attached along three sides. Such packages are typically made to be reclosable via the use of a reclosable element or fastener such as a resealable adhesive seal or a reclosable zipper. Such zippers may be opened and closed either by pressure or by the use of an auxiliary slider mechanism.
- Reclosable packages are a great convenience to consumers, especially for products such as luncheon meats and cheeses where, typically, only a portion of the product is used at any given time. A problem with these reclosable packages, however, is that the reclosable features do not provide a desired leak resistance. Thus, the contents of the package can leak out of the package and the external atmosphere can leak into the package, promoting food spoilage. Another problem with reclosable packages is that such packages can be tampered with prior to purchase by the customer.
- A further problem associated with a tamper evident feature is the inability of a food manufacturer to have flexibility in attaching the opposing body panels to the fastener. Specifically, it would be highly desirable to the food manufacturer to be able to attach the opposing body panels to either the interior surface or the exterior surface of the fastener. To increase manufacturing efficiency and/or reduce material usage, it would also be desirable to have some flexibility in locating the opposing body panels to the fastener on the interior or exterior surfaces.
- One attempt to address this problem has involved encapsulating the reclosable feature by extending the wall panels of the package. One disadvantage of this type of package is that the extended wall panels may interfere with the operation of opening and closing the package, resulting in customer dissatisfaction. Another disadvantage includes higher product costs involved with using additional resins for extending the wall panels. This type of package also involves an additional step for the customer of removing a tear strip or manually cutting the wall panels to gain access to the package.
- A need therefore exists for packages having a desired tamper evident seal in addition to having a reclosable feature.
- According to one embodiment of the present invention, a reclosable polymeric package comprises first and second opposing body panels, a reclosable seal and a onetime breakable element. The second opposing body panel is joined with the first opposing body panel along three sides to create a receptacle space having a mouth at one end. The reclosable seal extends along the one end and includes a first track and a second track. The first track includes a first fin portion and a first reclosable element. The second track includes a second fin portion and a second reclosable element. The first fin portion extends generally downwardly from the first reclosable element toward the receptacle space The first fin portion has a first end and a second end being further from the first reclosable element. The second fin portion extends generally downwardly from the second reclosable element toward the receptacle space. The second fin portion has a first end and a second end being further from the second reclosable element. The first reclosable element and the second reclosable element are releasably engageable to each other.
- The one-time breakable element initially extends from the first fin portion to the second fin portion so as to prevent or inhibit tampering with the package prior to being opened. The one-time breakable element is attached between respective first and second ends of the first and second fin portions. The first opposing body panel is adapted to be attached to an interior surface or an exterior surface of the first fin portion and the second opposing body panel is adapted to be attached to an interior surface or an exterior surface of the second fin portion. In other embodiment, at least one of the first and second opposing body panels is attached to the exterior surface of the respective first fin portion and the second fin portion.
- According to another embodiment, a fastener is adapted to be attached to a first opposing body panel and a second opposing body panel in forming a reclosable polymeric package. The fastener comprises first and second tracks, and a one-time breakable element. The first track includes a first fin portion and a first reclosable element. The first fin portion extends generally downwardly from the first reclosable element and has exterior and interior surfaces. The first fin portion has a first end and a second end being further from the first reclosable element. The second track includes a second fin portion and a second reclosable element. The second fin portion extends generally downwardly from the second reclosable element and has exterior and interior surfaces. The second fin portion has a first end and a second end being further from the second reclosable element. The first reclosable element and the second reclosable element are releasably engageable to each other.
- The one-time breakable element initially extends from the first fin portion to the second fin portion so as to prevent or inhibit tampering with the package prior to being opened. The one-time breakable element is attached between respective first and second ends of the first and second fin portions. The exterior and interior surfaces of the first fin portion are adapted to be attached to the first opposing body panel and the exterior and interior surfaces of the second fin portion are adapted to be attached to the second opposing body panel.
- Other objects and advantages of the invention will become apparent upon reading the following detailed description and upon reference to the drawings.
- FIG. 1 is a sectional view of a mouth portion of a reclosable package or bag with the opposing body panels attached to respective exterior surfaces of the fin portions according to one embodiment of the present invention;

- While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawing and will herein be described in detail. It should be understood, however, that it is not intended to limit the invention to the particular forms disclosed but, on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
- Turning now to the drawings, FIG. 1 depicts a mouth portion of a reclosable package or
bag 10 having a one-time breakable element or tamperevident feature 12 located below a reclosable closure arrangement such as fastener orzipper 14. FIG. 2 shows thereclosable package 10 with the mouth portion depicted in FIG. 1 in a partial open position. - Referring to FIGS. 1 and 2, the mouth portion of the
reclosable package 10 includes a pair of first and second opposing body orwall panels package body 20 and define areceptacle space 22. Connected to thefirst body panel 16 is afirst track 24 having afirst profile 26 and afirst fin portion 28 extending generally downward from thefirst profile 26. Connected to thesecond body panel 18 is asecond track 30 having asecond profile 32 and asecond fin portion 34 extending generally downward from thesecond profile 32. The first andsecond profiles package 10. - In the illustrated embodiment of FIG. 1, a one-time
breakable element 12 initially extends from thefirst fin portion 28 to thesecond fin portion 34. More specifically, the one-timebreakable element 12 is attached betweenends second fin portion 34. The one-timebreakable element 12 of FIG. 1 is depicted with an optional one-time breakable preferential area of weakness orpreferential tear area 38 to form a one-time breakable tamper evident feature. It is not necessary that the one-timebreakable element 12 has a one-time breakable preferential area ofweakness 38. For example, the one-timebreakable element 12 may be made in a manner to separate by cutting therethrough. The preferential area ofweakness 38 inhibits tampering with thebag 10 prior to being opened. The one-timebreakable element 12 has a generally U-shaped (see, e.g. FIG. 3) or V-shaped (see, e.g. FIG. 1) cross-sectional configuration. - The one-time
breakable element 12 may be extruded with thefin portions weakness 38. In one embodiment, the preferential area ofweakness 38 takes the form of a score line or a series of perforations (also referred to as a perforated line). A score line may be created by making a uniform crease in the general center of the one-timebreakable element 12. Alternatively, a score line may be formed on any portion(s) of the onetimebreakable element 12. A score line is created by extruding the one-timebreakable element 12 with less polymeric material along a portion thereof. In another embodiment, the preferential area ofweakness 38 results from forming the single continuous piece out of a region of highly oriented polymeric material that has a tendency to split along the preferential area ofweakness 38. - Instead of extruding the one-time
breakable element 12 with the first andsecond fin portions breakable element 12 and thefin portions breakable element 12 may be attached at ends 12 a, 12 b thereof torespective fin portions breakable element 12 may be attached to therespective fin portions breakable element 12 with thefirst fin portion 28 and/or thesecond fin portion 34 may create a preferential area of weakness. - The thicknesses of the one-time
breakable element 12 and the first andsecond fin portions breakable element 12 and the first andsecond fin portions - The
reclosable package 10 may further include an optional auxiliary slider mechanism 36 (FIG. 2) slidably mounted to thefastener 14 for movement between a closed position and an open position. Referring to FIGS. 1 and 2, the first andsecond profiles slider mechanism 36 is in the closed position, and movement of theslider mechanism 36 from the closed position to the open position disengages theprofiles - The
package 10 of FIG. 2 also includesend terminations 37. End terminations may have various purposes such as (a) preventing or inhibiting theslider mechanism 36 from going past the ends of thefastener 14, (b) interacting with theslider 36 to give a tactile indication of being closed, (c) assisting in inhibiting or preventing leakage from thepackage 10 and (d) holding the first andsecond profiles profiles package 10. Further details concerning the construction and operation of theslider mechanism 36 and theend terminations 37 may be obtained from U.S. Pat. No. 5,067,208 to Herrington, Jr. et al., which is incorporated herein by reference in its entirety. - It is contemplated that other end terminations may be used instead of the above-described
end terminations 37. For example, an end weld may be formed by heated bars pressed against the end of the fastener, ultrasonic welding or other ways known in the art. - As illustrated in FIGS. 1 and 2, in order to open the
reclosable package 10 of the present invention, a consumer grips theslider mechanism 36 and moves it such that the first andsecond profiles second tracks breakable element 12 along the preferential area ofweakness 38. Alternatively, the consumer may open the one-timebreakable element 12 by cutting therethrough. The package can be resealed utilizing thefastener 14 andslider mechanism 36. Specifically, the consumer grips theslider mechanism 36 and moves it from the open position to the closed position so as to engage the complementary first andsecond profiles - The one-time
breakable element 12 not only provides a consumer with the assurance that his or her newly purchased package has never been opened before, but also provides a good initial seal which preserves the freshness of the food contents of the package prior to its initial opening. Since the reclosable closure arrangements of FIGS. 1-5 are located above the one-time breakable element, (i.e., the reclosable closure arrangement is further from the receptacle space), the operation of the reclosable closure arrangement is not hampered by the presence of the one-time breakable element. - For example, it is not preferred to have pull flanges that extend upwardly from the reclosable closure arrangement that can be grasped and pulled apart to open the reclosable closure arrangement from a sealed form. Such a reclosable package may interfere with the operation of opening and closing the package, resulting in customer dissatisfaction. Additionally, this type of package also includes another step for the customer of removing a tear strip for the customer of removing a tear strip or manually cutting the wall panels to gain access to the package. This type of package also includes higher product costs involved with using additional resins for extending the body panels.
- The tracks, profiles, fin portions and one-time breakable element typically comprise one or more polymeric resins. The tracks, profiles, fin portions and one-time breakable element may be independently comprised of one or more polyolefins including, but not limited to, polyethylenes, polypropylenes or combinations thereof. Some non-limiting types of polyethylenes include low density polyethylenes (LDPE), linear low density polyethylenes (LLDPE), high density polyethylenes (HDPE), medium density polyethylenes (MDPE) and combinations thereof. Other non-limiting examples include plastomers, elastomers, ethylene vinyl acetates (EVA), ethyl methacrylates, polymethylpentene copolymers, polyisobutylenes, polyolefin ionomers, cyclic olefin copolymers (COCs) or combinations thereof, including with polyethylenes and/or polypropylenes.
- One or more of the tracks, profiles, fin portions and/or one-time breakable element may be made from multiple layers. The multiple layers of the tracks, profiles, fin portions and one-time breakable element may be independently formed by coextruding or other processes such as coating or laminating.
- The opposing films forming the opposing
body panels body panels - Furthermore, the opposing
body panels - The
optional slider mechanism 36 may be formed from suitable polymeric materials such as, for example, nylon, polypropylene, polyethylene, polystyrene, copolymers of polyethylene and polypropylene, polycarbonates, polyesters, polyacetals, or acrylic-butadiene-styrene copolymers. Especially preferred components for making theslider mechanism 36 are polypropylenes, polycarbonates or polyesters. Theslider mechanism 36 may be formed by injection molding. - As discussed, the one-time breakable element may be formed from one or more layers. According to one embodiment, the one-time
breakable element 12 may also be a barrier partition that includes a barrier layer that is substantially impermeable to at least one of oxygen, nitrogen, carbon dioxide and/or water vapor. The optional preferential area ofweakness 38 of the one-timebreakable element 12 may also be substantially impermeable to at least one of oxygen, nitrogen, carbon dioxide and/or water vapor. If substantially impermeable to at least oxygen, nitrogen, carbon dioxide and/or water vapor, the one-timebreakable element 12 assists in preserving the freshness of the food contents of the package prior to its initial opening. The freshness of the food is preserved by reducing gases from the external atmosphere causing food spoilage. - The optional barrier layer of the one-time
breakable element 12 may comprise ethylene vinyl alcohols (EVOH), polyvinyl alcohols (PVOH), nylons, polyesters, ethylene vinyl dichlorides (EVDC), liquid crystal polymers (LCPs), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), modified polyolefins with barrier properties, polyacrylonitriles, acrylonitrile copolymers, polyacetals, cellophanes, cyclic olefin copolymers (COCs) or combinations thereof. More specifically, the optional barrier layer of the one-timebreakable element 12 is made of an EVOH, PVDC, nylon or polyester. Preferred nylons include nylon-6, nylon-66, nylon-MXD6 and amorphous nylons. Preferred polyesters include polyethylene terephthlate (PET) and polybutylene terephthlate (PBT). - If it is desirable to have an effective water vapor barrier, a cyclic olefin copolymer such as TOPAS® 8007 may be used. TOPAS® 8007 is made by Ticona, a buiness of Calanese A G, in Summit N.J. This cyclic olefin copolymer is believed to be prepared with feedstocks of norbornene and ethylene and the use of a metallocene catalyst. The TOPAS® 8007 has a glass transition temperature, Tg, of about 85° C. with a norbornene level believed to be about 39 mole %.
- There are believed to be at least three other grades of TOPAS® resins available (TOPAS® 6013, TOPAS® 6015 and TOPAS® 6017). Other companies that have cyclic olefin copolymers available include Nippon Zeon (Japan), Mitsui Chemical (Japan) and JSR (Japan), formerly know as Japan Synthetic Rubber. These cyclic olefin copolymers are believed to be prepared with feedstocks of norbornene and ethylene and the use of a metallocene catalyst. The three grades of TOPAS® resins available have glass transition temperatures, Tg, of 140, 160 and 180° C., respectively. The corresponding norbornene levels of the four grades of TOPAS® resins are believed to be about 48, 55 and 59 mole %.
- It is preferred that water soluble materials, such as PVOH, do not comprise the optional barrier layer if the one-time
breakable element 12 is made of only the barrier layer because those materials may dissolve in a moisture environment, lose strength and/or barrier characteristics. - According to one embodiment, a five layer barrier layer is contemplated. The five layer barrier layer has polymeric outer layers such as, for example, high density polyethylene (HDPE), ultra low density polyethylene (ULDPE) and low density polyethylene (LDPE). The interior layer is made of ethylene vinyl alcohol (EVOH). The EVOH layer is attached to the outer polymeric layers via adhesive layers such as ethyl vinyl acetate (EVA). Another example of an adhesive that may be used in PLEXAR® 165, which is described as an anhydride modified LDPE, ans has a melt index (MI) of 1.8 g/10 min. and a density of about 0.92 g/cm3.
- The optional barrier layer generally has an oxygen transmission rate (OTR) less than 10 cm3 (mil)/100 in2-day at 23° C. as measured by ASTM D3985-81. The barrier layer preferably has an oxygen transmission rate less than 2 cm3 (mil)/100 in2-day at 23° C. and, more preferably, less than 0.5 cm3 (mil)/100 in2-day at 23° C. as measured by ASTM D3985-81.
- The optional barrier layer may also be substantially impermeable to water vapor and other gases causing dehydration, increased humidification and/or oxidation. The optional barrier layer generally has an water vapor transmission rate (OTR) less than 20 g/100 in2-day at 23° C. as measured by ASTM F1249-90. The ASTM F1249-50 has been slightly modified in Section 11.2 to normalize and account for the small width of the track. The barrier layer preferably has an oxygen transmission rate less than 5 g/100 in2-day at 23° C. and, more preferably, less than 1 g/100 in2-day at 23° C. as measured by ASTM F1249-90.
- The optional barrier layer may assist in inhibiting loss of flavor, absorption of external odors and development of microflora (bacteria) in the food products of the
package 10. - It is contemplated that oxygen absorbers/scavengers may be included in forming the optional barrier layer. Oxygen absorbers or scavengers are generally chemical or enzyme based. Chemical oxygen scavengers contemplated in the present invention include metallic reducing agents such as various ferrous compounds, powdered iron oxide and metallic platinum. Other chemical oxygen scavengers include non-metallic formulations such as those employing ascorbic acids (Vitamin C) and their associated salts and organo-metallic molecules that have a natural affinity for oxygen.
- It is contemplated that additional materials may be added in forming the optional barrier layer. These materials include various fillers, such as clay, talc, mica and nanocomposites that may be more cost effective. These fillers may provide a tortuous path for oxygen, nitrogen, carbon dioxide and/or water vapor.
- Similarly, the opposing
body panels 16, 18 (such as depicted in FIGS. 1, 3 and 4) may also be made of at least one barrier layer that is substantially impermeable to at least one of oxygen, nitrogen, carbon dioxide and/or water vapor. The optional barrier layer of the opposingbody panels breakable element 12. The optional barrier layer of the opposingbody panels package 10. - The opposing
body panels body panels fin portions - An example of a three layer body panel (not shown) includes a first layer having the same materials as described above in making the optional barrier layer of the one-time
breakable element 12, a tie layer and a third layer made of polyolefin(s), such as an LDPE, an HDPE, an LLDPE or combinations thereof. In this embodiment, the first layer would be preferably located on the interior of the body panel with the tie layer being located between the first and third layers. - The components of the reclosable closure arrangement (such as the tracks having integrally formed interlocking profiles and fin portions) may be attached to the body panels of the package by processes such as heat sealing, welding or blocking. The process utilized depends upon the materials from which the bag and the reclosable closure arrangement are made. Specifically, heat sealing is a process whereby materials are fused or melted together. Welding is a process where an intermediate third material is utilized to “glue” similar materials to each other. Blocking is a process where at least sufficient pressure and optional temperature increases result in intimate surface contact adhesion of layers without sealing.
- Examples of the body panels being attached to the fin portions are depicted in FIGS. 1, 3 and4. Referring back to FIG. 1, the
body panels fin portions reclosable package 110 is shown that includes afastener 14 with a one time-breakable element 112 that is generally U-shaped. The opposingbody panels fin portions receptacle space 122. The ability to attach to either the exterior surface or in the interior surface of the fin portions gives much greater process latitude during the filling of the bag. - Referring to FIG. 4, a
reclosable package 210 is depicted that includes afastener 14 with a one time-breakable element 12 that is generally V-shaped. Thefirst body panel 16 of FIG. 4 is attached to an exterior surface of thefin portion 28, while the second body panel is attached to an interior surface of thefin portion 34 and thebody panels receptacle space 222. It is contemplated that the one-time breakable element may take other shapes such as the reverse orientations of the general U-shaped (FIG. 1), or general V-shaped (FIG. 4) one-time breakable element. Other contemplated shapes include a general W-shaped one-time breakable element and the reverse orientation thereof. - The location of the attachment of the
body panels fastener 14 may assist in increasing the volume or interior space of the bag with a similar amount of polymeric film. For example, if the attachment of thebody panels fin portions 28, 34 (i.e., located further away from the profiles), then the volume or interior space of the bag is increased with a similar amount of polymeric film. - Additionally, the
fin portions bag 310 with lengthened or extendedfin portions fin portion 328 extends from afirst end 328 a to asecond end 328 b thereof, while thefin portion 334 extends from afirst end 334 a to asecond end 334 b thereof. Thebag 310 of FIG. 5 is shown in an position where theprofiles breakable element 12 remains intact. Thebag 310 has an increasedinterior space 322 with thebody panels fin portions body panels fin portions breakable element 12 until the respective first ends 328 b, 334 b shown in FIG. 5) may also be used for graphic printing thereon. The extended fin portion also allows for an extended sealing area between the body panels and the respective fin portions. - Alternatively, an adhesive seal may be utilized as a fastener or reclosable element of the present invention. Such seals employ a resealable adhesive-type substance that is applied to either one or both of the films forming the package. The adhesive may alternatively be applied to an intermediary base strip. It is contemplated that other closure arrangements, besides adhesive seals and zippers, may be used in the present invention.
- While the present invention has been described with reference to one or more particular embodiments, those skilled in the art will recognize that many changes may be made thereto without departing from the spirit and scope of the present invention. Each of these embodiments and obvious variations thereof is contemplated as falling within the spirit and scope of the claimed invention, which is set forth in the following claims.
