Definitions

  • the present invention relates generally to packaging for condiments. More particularly, the present invention concerns condiment packaging adapted for opening in at least two different ways.
  • Condiment packaging has evolved over the years, starting with basic glass bottles and jars for display and sale of condiments, including without limitation ketchup, mustard, mayonnaise, sauces, and the like. That basic packaging later included larger capacity bottles and jars, and then containers made from synthetic plastic materials. Eventually, the packaging concepts turned to providing packaging suitable for individual portions of the condiments.
  • Condiment packages having a generally rectangular receptacle portion covered with a substantially planar sheet have been long known also. See, for example, U.S. Pat. No. 2,705,579. Such condiment packages were later provided with breakaway corners and exposed corners for the covering material, thereby providing different access means for the condiment packaged therein. See, for example, U.S. Patent Application Publication Nos. 2003/0183637, and 2002/0100760.
  • receptacle portion has a generally frustoconical shape with a spout at one side. See, for example, U.S. Pat. Nos. 2,898,003, 3,660,960, and 4,863,036. Typically, receptacles having this configuration have been used for relatively low viscosity products such as milk and cream.
  • Squeezable packages for products are also known where the package has a spout at one end and the forming materials are weakened in the vicinity of the spout to permit access to the contents thereof. See for example, U.S. Pat. Nos. 5,529,224, 4,921,137, and WO 2007/126817.
  • Containers for liquids have also been proposed which permit dual access modes. For example, one mode allowing squeezing for product removal and another mode allowing dipping for product removal. See, for example, U.S. Patent Application Publication No. 2006/0278562 (commonly owned, the entire contents of which are incorporated herein by this reference thereto). It has been proposed to use different opening methods where the product has different consistencies. See, for example, Fr. Patent No. 2,801,570. Moreover, various designs for containers which permit the varied kinds of access have also been disclosed. See, for example, U.S. Patent Application Publication No. 2007/0164045.
  • the word “condiment” should be interpreted broadly so as to include substances used to enhance larger food portions.
  • “condiment” is intended to cover traditional condiments such as ketchup, mustard, mayonnaise, tartar sauce, and the like, as well as to encompass, without limitation, other comestibles such as sauces, jellies, jams, honey, and the like.
  • the improved condiment container according to this invention includes a cover portion and a container portion.
  • the container portion preferably includes a receptacle proportioned to receive a predetermined volume of a condiment.
  • the predetermined volume corresponds to the quantity of the condiment that a consumer may personally use during consumption of a meal.
  • the receptacle of the container portion includes a generally planar bottom surface with a nominal length and a nominal width.
  • the bottom surface provides a stable surface to support the condiment container during certain aspects of its use by a consumer.
  • the receptacle also has a nominal depth selected in relation to the nominal width and nominal length to provide a receptacle that is low, wide, and stable against lateral tipping when a food item is thrust or poked into the receptacle.
  • the container portion preferably includes a flange extending substantially continuously around the receptacle.
  • the flange is generally planar, is spaced from the generally planar bottom surface, and parallel thereto.
  • a spout is provided at one side of the receptacle and at the position of the flange.
  • the spout has cross-sectional area which is smaller than the cross-sectional area of the opening at the upper edge of the receptacle. In this manner, access to the condiment through the spout is much more restricted that access to the condiment through the upper edge of the receptacle.
  • the container portion is fashioned from a material having a first bending stiffness sufficient that the receptacle retains its shape, even in the absence of the cover portion. Moreover, that first bending stiffness is also sufficient to ensure that the flange will retain its shape and orientation relative to the receptacle, even in the absence of the cover portion.
  • container portion may be fabricated from a material selected from the group consisting of polyethylene terephthalate (PET), amorphous polyethylene terephthalate (APET), oriented polyethylene terephthalate (OPET), metalized polyethylene terephthalate (MET-PET), polyethylene (PE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), metalocene linear low density polyethylene (mLLDPE), high density polyethylene (HDPE), metalocene polyethylene (mPE), ethylene vinyl acetate (EVA), polypropylene (PP), metalized oriented polypropylene (mOPP), polystyrene (PS), high impact polystyrene (HIPS), foil, ethylene vinyl alcohol (EVOH), polyamide, Nylon, polyvinyl chloride (PVC), biaxially oriented materials, materials complying with 21 C.F.R.
  • PE polyethylene terephthalate
  • APET amorphous polyethylene terephthalate
  • OPET
  • the container portion may comprise a single layer of material, the container portion may also be fabricated of multiple layers bonded, coextruded or otherwise formed together into a cohesive structure, where one or more of the layers is selected from the group of materials set forth above. Regardless of the particular composition used for the lid portion, all surfaces of the lid portion which face the receptacle are required to be food-safe.
  • the thickness of the container portion may preferably lie in the range of about 3 mils to about 20 mils—a mil being 0.001 inches.
  • the cover portion is substantially planar and preferably is configured to have a perimeter substantially the same as the perimeter of the container portion. Moreover, the cover portion substantially covers the flange of the container portion.
  • the cover portion is preferably fabricated from a material having a second bending stiffness, where the bending stiffness of the cover portion is lower than the bending stiffness of the container portion. This difference in stiffness causes the cover portion to be more flexible and more readily separable from the container portion along the flange.
  • the material from which the cover portion is fabricated may be the same as, or different from, the material used for the container portion. Accordingly, the material of the cover portion may be selected from the group consisting of PET, APET, OPET, MET-PET, PE, LDPE, LLDPE, mLLDPE, HDPE, mPE, EVA, PP, mOPP, PS, HIPS, foil, EVOH, polyamide, Nylon, PVC, biaxially oriented materials, materials complying with 21 C.F.R. Part 177, and combinations thereof. Typically, the thickness of the cover portion will lie in the range of about 1 mil to about 5 mils.
  • cover portion may comprise a single layer of material
  • the cover portion may also be fabricated of multiple layers bonded, co-extruded or otherwise formed together into a cohesive structure, where one or more of the layers is selected from the group of materials set forth above. Regardless of the particular composition used for the lid portion, all surfaces of the lid portion which fact the receptacle are required to be food-safe.
  • an adhesive is preferably positioned between the cover portion and the container portion, in the flange area, and surrounding the top edge of the receptacle.
  • the adhesive preferably is a food-grade adhesive and may be conventionally cured, for example, thermally, electromagnetically, or time cured.
  • the adhesive is integral with the cover portion and/or the container portion. Application of heat and pressure can be used to cause the adhesive to bond the cover portion and/or the container portion.
  • adhesive may be applied around the receptacle of the container portion in a separate step.
  • the adhesive is applied such that the adhesive defines a non-bonded region in alignment with the spout, although the adhesive otherwise surrounds the spout.
  • pressure may be applied to assure that the adhesive bonds the cover portion and the container portion so as to define a sealed compartment defined by the receptacle and the cover portion. Moreover, the adhesive is applied such that an non-bonded region exists between the lid portion and the flange of the container portion in general alignment with the spout.
  • the non-bonded region is located opposite the spout and at the periphery of the container assembly.
  • the non-bonded region is operable to define a lift tab at an edge of the lid portion.
  • the lift tab is graspable so that it can be pulled away from the flange of the container portion so as to expose the receptacle and the contents thereof.
  • the adhesive is applied such that a peel-initiating region, such as a substantially angular region, partially defines an edge of the non-bonded region.
  • the peel-initiating region is engaged as the lid portion is pulled by the tab from the container portion before the lid portion engages the full linear extent of the adhesive extending from side to side of the receptacle, and offers reduced resistance to separation between the lid portion and the container portion of the assembled package.
  • the required opening force may lie in the range of 1 to 5 lbs.
  • the non-bonded region and the peel-initiator may be positioned in alignment with the spout or on the opposite side of the receptacle. Regardless of the position, when the lid portion is peeled back away from the container portion, the receptacle is exposed so as to be available for dipping a food item in the condiment.
  • a weakened area is preferably positioned so as to be transverse to the spout.
  • the weakened area may be provided by mechanically cutting or fracturing the package materials in the vicinity of the spout.
  • the weakened area may be fashioned by cutting the lid portion and the container portion so that a pair of aligned slits straddle the spout.
  • the weakened area may be provided by laser scoring either the lid portion or the container portion or both. The end of the assembled container may then be broken away along the weakened area to expose the spout. By then squeezing the assembled container, the condiment will be released through the spout in a controlled manner.
  • the adhesive preferably has sufficient strength that the container will resist bursting when subjected to a force of 50 lbs. or greater, and preferably when subject to a force of 70 lbs. or greater.
  • the container assembly may be adapted for attachment to the sidewall of a paperboard container.
  • a pair of slits may be provided in the container and extending through both the lid portion and the container portion, where the slits are symmetrically disposed and cooperate to define a pair of ears.
  • the ears can be bent out of the plane of the flange to define an angular (when viewed from the side) hook. Resilience of the materials used to fabricate the lid portion and the container portion cooperates to pinch an edge of the paperboard container.
  • the surface of each ear may be suitable treated. For example, a tacky coating, or a roughened surface may be provided for such a purpose.
  • either or both of the lid portion and the container portion may include an oxygen control barrier or an oxygen scavenger layer. Such a barrier layer can be helpful to reduce or eliminate degradation of the condiment packaged in the container assembly. If desired, either or both of the lid portion and the container portion may be opaque. Opaqueness may enhance the packaged product where exposure to light degrades the product over time.
  • shelf-life When the condiment packaged in the container is ketchup, the materials for the lid portion and the container portion are preferably selected such that the packaged condiment will have a shelf-life of at least about six months.
  • One technique for evaluating shelf-life involves use of a colorimeter operating in the L*a*b* color space. Shelf-life may be evaluated by monitoring degradation of the color components of the packaged product according to measurements in that color space. For example, shelf-life may be determined by requiring that the L* and/or the ratio of a*/b* does not degrade more than a specified amount during the specified period, e.g., by less than 10% over a six-month period.

  • One suitable material for an oxygen control layer is EVOH which can function not only as an oxygen barrier but may also function as a moisture barrier.
  • the material from which the lid portion 24 is fabricated may be transparent, translucent, or opaque. Moreover the material may be colored, if desired.
  • the cup portion 22 (see FIG. 2 ) includes a receptacle 30 which extends away from the flange 26 and includes a generally planar bottom surface 32 which may be generally rectangular.
  • the receptacle 30 includes a sidewall 36 extending between the bottom surface 32 and the flange 26 .
  • the flange 26 extends generally radially from the edge 40 (see FIG. 2 ) and defines a substantial area which is exposed until the lid portion 24 is applied.
  • one side of the receptacle may include a generally triangular or generally trapezoidal surface 34 which is inclined relative to the generally planar flange 26 and the bottom surface 32 .
  • a spout 38 is provided at one side of the receptacle 30 .
  • the cup portion 22 is designed so as to be symmetrical about a longitudinal plane extending perpendicularly to the plane of FIG. 5 and generally coincident with the line 9 - 9 .
  • the lid portion 24 When the lid portion 24 is in place, that symmetry of the cup portion 22 coupled with the inclined surface 34 and the lid portion 24 creates a funnel or converging cross-sectional area at the side of the receptacle so that the funnel communicates with the spout 38 .
  • the spout 38 exhibits a cross-sectional area that is much smaller than the area exposed at the top edge of the receptacle 34 (see FIG. 4 ).
  • the cup portion 22 (see FIG. 3 ) is preferably fabricated from a material that is more rigid than the stock from which the lid portion is made. Thus, the bending stiffness of the cup portion 22 exceeds the bending stiffness of the lid portion 24 . That difference in stiffness makes the lid portion more readily deform for removal and opening of the assembled container.
  • the cup portion 22 is stiffer than the lid portion 24 , the cup portion 22 preferably is sufficiently pliable that it can be deflected by squeezing with hand pressure—i.e., pressure applied by fingers of an unaided human hand. Nevertheless, the cup portion 22 is sufficiently stiff that it does not deform or deflect in the absence of force.
  • the cup portion 22 can be supported by the bottom surface to provide a sufficiently rigid container to hold a condiment without spilling.
  • the generally planar flange 26 extending outwardly from the perimeter 40 of the receptacle also functions to stiffen the receptacle region of the cup portion 22 .
  • a bottom surface 32 (see FIG. 4 ) having increased stiffness.
  • Such an increased stiffness may be accomplished by providing an embossed feature 44 in the bottom surface 32 .
  • Such an embossed feature 44 may also extend onto the inclined surface 34 , if desired.
  • that embossed feature 44 may comprise a logo of the manufacturer. The enhanced stiffness results from the depth of the embossed feature 44 relative to the plane of the bottom surface 32 .
  • the material from which the cup portion 22 is fabricated may be selected from the same group of materials available for the lid portion 24 , namely the group consisting of PET, APET, OPET, MET-PET, PE, LDPE, LLDPE, mLLDPE, HDPE, mPE, EVA, PP, mOPP, PS, HIPS, foil, EVOH, polyamide, Nylon, PVC, biaxially oriented materials, materials complying with 21 C.F.R. Part 177, and combinations thereof. Where foil is used, that foil may be an aluminum foil, or other metal foil. Typically, the thickness of the cup portion 22 will lie in the range of about 3 mils to about 20 mils.
  • the cup portion 22 may have a thickness in the range of about 8 mils to about 12 mils.
  • the thickness of the cup portion 22 is selected to be less flexible than the lid portion 24 so that the lid portion 24 can be pulled away from the cup portion 22 overcoming the tackiness of the adhesive.
  • the receptacle of the condiment container 20 is preferably sized to contain a suitable individual serving of the condiment, for example, a nominal volume of about one ounce. While larger and smaller nominal volumes are within the scope of this invention, the nominal volume will generally correspond to the quantity of the particular condiment desired by a typical individual.
  • the receptacle portion of the package has a nominal width corresponding to the maximum distance between the opposed sidewalls at the location of the edge 40 and extending transverse to the plane of symmetry between opposed sidewalls, a nominal length being the maximum length between sidewalls of the receptacle at the location of the edge 40 and measured along the plane of symmetry, and a nominal depth (see FIG. 4 ) also measured in the plane of symmetry but extending from the bottom surface 32 to the flange 26 . These nominal dimensions define the nominal volumetric capacity for the receptacle portion.
  • the cup portion 22 Another important feature of the cup portion 22 is lateral stability against tipping. Furthermore these nominal dimensions can be used to establish guidelines that provide adequate tipping stability. More specifically, the ratio of the nominal height to the nominal width is preferably less that about 0.5, and more preferably less than about 0.45. In addition, the ratio of the nominal height to the nominal length is preferably less that about 0.3, and more preferably less than about 0.26. When the receptacle of the cup portion 22 has nominal dimensions within these ranges, the receptacle is sufficiently stable that it does not tip when a food item is dipped in the condiment contained therein.
  • the lid portion 24 and the cup portion 22 are sealed together using a food-grade adhesive so as to define an encapsulated volume isolated from the environment.
  • a food-grade adhesive so as to define an encapsulated volume isolated from the environment.
  • One technique for accomplishing the seal is to include a heat-sealable layer on the inside of the lid portion 24 and on the inside of the cup portion 22 .
  • the adjacent surfaces bond together forming the appropriate seal surrounding the periphery of the edge 40 of the receptacle.
  • a suitable food-grade adhesive compatible with the materials of the container may be used.
  • the adhesive is preferably applied so as to surround the edge 40 of the receptacle (see FIG.
  • the condiment container is capable of withstanding an applied force of at least about 50 lbs without bursting or breaking through the seal. More preferably, an applied force of about 70 lbs. will not burst the seal.
  • the adhesive preferably extends to the peripheral edge 50 of the flange 26 , but provides an non-bonded region 52 at one side of the receptacle. That non-bonded region 52 extends inwardly along the flange 26 from the peripheral edge 50 of the flange by a distance sufficient that a pull-tab portion 54 (see FIG. 5 ) of the lid portion 24 not adhesively connected to the flange 26 is sufficiently large to be graspable between fingers. A distance of about 0.5 inches or more is graspable for the pull-tab 54 . It will be apparent to those skilled in the art that attempting to peel a lid portion away from the flange 26 (see FIG. 3 ) is difficult due to the width of the seal.
  • the tab 54 can be grasped to pull the lid portion 24 away from the flange 26 of the cup portion 22 to expose the receptacle and its contents. Such a step would prepare the container for dipping a food item into the condiment.
  • a different opening scheme is also available with the container of this invention. More particularly, the container may be provided with a weakened region in the vicinity of the spout 38 for the purpose of opening the spout 38 as an alternative to removal of the lid portion 24 .
  • the weakened region may, for example, comprise a pair of aligned slits 60 , 62 in the vicinity of the spout 38 .
  • the slits 60 , 62 are aligned with one another and straddle the spout 38 .
  • the slits 60 , 62 may extend through the thickness of both the lid portion 24 and the cup portion 22 .
  • the distal end of the container 20 can be bent to fracture the material of the container and expose a channel through the spout 38 into the receptacle. At that point application of pressure to the receptacle will cause the condiment to be expelled through the spout 38 in directionally controlled and defined way.
  • the aligned slits 60 , 62 can be applied to the container before, during, or after assembly of the condiment container 20 .
  • an efficient mechanical way of creating the aligned slits 60 , 62 is to form them at the same time that the lid portion 24 is applied to the cup portion 22 and adhesively connected thereto.
  • a laser scoring process may be employed to weaken the container around the spout 38 so that an end of the container can be snapped or twisted off to expose the end of the spout passage.
  • the materials selected for the lid portion 24 , the cup portion 22 , and the adhesive are preferably chosen so that the condiment has a desired shelf life.
  • a shelf-life of at least six months is desirable.
  • shelf-life can be evaluated by changes in the color characteristics of the condiment. Testing for shelf-life can, therefore, be conducted using colorimetric analyses.
  • the Hunter Lab color space and the L*a*b* color space use three coordinates to define any particular color. For example, in the L*a*b* color space, the coordinates L*, a*, and b* define the three-dimensional color space.
  • the L* component measures lightness and correlates particularly well with human eye perceptions.
  • the L* value ranges between 0 corresponding to pure black and 100 corresponding to pure white.
  • the a* coordinate measures the color position between red/magenta and green, with negative values indicating green and positive values indicating magenta.
  • the b* component measures the color position between yellow and blue, with negative values indicating blue, while positive values indicate yellow. Accordingly, changes in ketchup color over time can be evaluated by the value of and changes in the value of the L*, a*, and b*, or L, a, b components.
  • the lightness component, L* or L provides a reliable parameter to correlate with shelf-life.
  • the shelf-life requirement is satisfied.
  • the ratio of a*/b* or a/b is also indicative of product degradation.
  • satisfactory shelf-life may be determined when the L* (or L) component and the a*/b* (or a/b) ratio remain within about 10% of their initial values, respectively.
  • Other condiments for which color changes over time can also be colorimetrically evaluated for shelf-life using one or more of the L*a*b* color space components.
