Definitions
- the present invention relates generally to an article of manufacture for use in the packaging of fresh produce and more specifically to a packaging system and method which incorporates modified atmosphere packaging technology.
- the fresh produce industry incorporates the use of stackable corrugated fiberboard cartons or returnable plastic crates of various sizes and shapes to accommodate a wide array of fresh fruits and vegetables for transportation to market, hi general, there are two broad categories of stackable fiberboard cartons used in the produce industry, open style cartons which incorporate apertures such as hand-holds and concavities for refrigerated air circulation and closed style cartons which do not include the apertures and concavities but does incorporate selective gas permeable membranes to limit gas exchange between the sealed cartons and ambient atmosphere.
- the main advantages of the open style cartons allows for direct field packing of the harvested produce in the cartons, followed by refrigeration and shipment to market.
- the simple packaging and cooling of the produce provides significant time, labor and cost savings.
- the main disadvantages of this type of packaging is that the free movement of oxygen around the produce reduces the amount of time the produce can be stored and/or transported. To offset some of these deleterious effects, produce is harvested earlier in the growing season, usually before optimal nutritional values and desirable tastes have developed, thus reducing the quality of the produce delivered to market.
- Another disadvantage of the open style packaging is the minimal protection afforded to temperature excursions occasionally encountered during transportation to market.
- the lack of insulating air and packaging materials surrounding the produce allows temperature changes to more rapidly impact the stored produce. For temperature sensitive produce, (e.g., peaches) an extended refrigeration failure could result in the loss of an entire produce shipment.
- Examples of typical stackable containers include US patent 5,121,877 to Bodary, et al. which discloses a palletized containers for ripening of fruit during shipment and storage; US patent 3,871,570 to Garmon which discloses a stackable tray for shipping of fresh fruits and vegetables; US patent 5,967,406 to Moorman which . discloses a stackable Bliss style shipping container which can be reconfigured into a retail, club or wholesale market display container; US patent 5,052,615 to Ott, et al. which discloses another stackable shipping and display carton; US patent 4,101,048 to Rieben, et al. which discloses another stackable produce field carton; and US patent 3,863,831 to Wozniacki, et al. which discloses a stackable shipping carton which allows ventilation and/or cooling of the contents of the carton.
- the product life extension capability of MAP is extremely important in the premium fresh produce industry where considerable cost savings over regular cartons may be obtained where such produce would have to be air shipped rather than using considerably less expensive shipping alternatives such as cargo vessels and/or land transportation.
- the sealed packaging also affords greater protection from temperature excursions due to the increased insulating properties of the modified atmosphere and enveloping carton surrounding the produce.
- the are however, several disadvantages to the relevant art modified atmosphere packaging including difficulties in efficiently re-refrigerating palletized or stacked produce during shipment due to the inability to provide adequate refrigerated air circulation around the palletized and/or stacked produce cartons, in particular interior cartons which are insulated from the refrigerated air by the surrounding exterior cartons.
- corrugated package which incorporates modified atmosphere technology, allows field harvesting and packaging of produce in either the field or in a centralized facility, allows cooling ventilation of stacked and/or palletized packages directly in the modified atmosphere packaging, allows visual inspection of the packaged produce at any point following packaging and provides the ability to re-establish refrigeration of the produce during transit is highly desirable.
- the first object of the invention is to provide a modified atmospheric package which allows packaging of produce either in the field or in a centralized plant.
- a second object of the invention is to provide a modified atmospheric package which allows refrigeration of the produce after placement in the modified atmospheric packaging.
- a third object of the invention is to provide a modified atmospheric package which includes a transparent lid which allows visual observation of the packaged produce at any point following placement in the container to arrival at a final destination.
- a sixth object of the invention is to provide a modified atmospheric package which allows detection of tampering, produce decay, produce damage, insect infestation and temperature range excursions.
- a ninth object of the invention is to provide a combination modified atmospheric package in which the MAP technology is incorporated into one or more selective permeable membranes in the form of patches.
- the patches being installed over one or more apertures in either or both the transparent lid and/or standard corrugated fiberboard carton.
- a tenth object of the invention is to provide a packaging system which allows direct retail shelf placement and display without requiring removal of the fresh produce.
- An eleventh object of the invention is to provide a packaging system which meets or exceeds US Department of Agriculture export requirements for packaging.
- This invention addresses the limitations described above and provides a modified atmosphere packaging system and method which allows field harvesting and packaging of produce in either the field or centralized facility, allows cooling ventilation of stacked and/or palletized packages directly in the modified atmosphere packaging, allows visual inspection of the packaged produce at any point following packaging and provides the ability to reestablish refrigeration of the produce during transit is highly desirable.
- MAP modified atmosphere packaging
- carton is intended to include a box or tray.
- the invention comprises a bulk packaging system which incorporates at least one selective gas permeable membrane.
- the carton includes an open top, a closed bottom and a plurality of side walls joined to the bottom of the carton.
- the side walls and the bottom of the carton define an interior storage volume for storing fresh produce.
- the carton has either a square or rectangular shape and includes a generally air tight barrier such as liner when the selective gas permeable membrane is associated with a lid.
- the bulk packaging system further includes a transparent lid of • polymeric construction having a length and a width which conforms to a length and a width of the carton and sized to completely cover the open top and at least a portion of an exterior surface of the side walls of the carton.
- the lid further includes an interior surface, an exterior surface, four corners, and a plurality of raised stacking support structures disposed at about each of the four corners.
- the raised stacking support structures includes a predefined height sufficient to provide an air gap between a bottom of another corrugated carton and the exterior surface of the lid when vertically stacked two or more high. In one embodiment of the invention, the predefined height is at least one half centimeter.
- the plurality of raised stacking support structures further provides a sealable interior void space contiguous with the interior storage volume which allows accumulation of respiratory gases generated by the packaged produce and/or maintains a cover gas within the interior storage volume.
- the bulk packaging system incorporating at least one selective gas permeable membrane may be implemented by accomplishment of the following steps:
- FIG. 3B - Figure 3B depicts a perspective view of another alternate embodiment of the invention.
- FIG. 5 - Figure 5 depicts a perspective view of the basic embodiment of the invention shown in a palletized arrangement.
- the lid 5 includes a plurality of generally rectangular or triangular, raised stacking structures 15 disposed at about each of the four corners of the lid 5.
- each of the raised stacking structures 15 includes a horizontal groove 25 running longitudinally through each raised stacking structure 15.
- the grooves 25 are laterally offset from a lateral centerline of the raised stacking structure 15 such that each groove 15 is disposed closer to a nearest lateral edge of the lid 5.
- Each groove is uniformly aligned on a longitudinal axis of a lid such that longitudinally adjacent grooves are disposed about the same distance from the nearest lateral edge of the lid 5.
- the height of each of the raised stacking structures 15 is at least 0.5 cm above an average horizontal surface of the lid 5, generally in a range of 0.5 cm to 5 cm.
- the height of the raised stacking structures 15 provides an air gap between a bottom of another carton which allows cooling air to flow both laterally and longitudinally across an exterior surface of the lid 5 and the bottom of another carton when vertically stacked two or more high and/or when uniformly placed in multiple columns and rows on a pallet.
- each of the raised stacking structures 15 allows cooling airflow to penetrate between opposing stacking structures.
- An underside of each raised stacking structure 15 forms a sealed depression in the lid 5 which provides a headspace internal to the carton for accumulating respiratory gases generated by the produce and may also be used to maintain a reservoir of cover gas if required for maintaining a particular type of produce.
- the lid 5 in an alternate embodiment of the invention, includes a selliform depression between both adjacent lateral and longitudinal raised stacking structures 15 such that an underside of the lid 5 conforms to the top vertical edges of a Bliss or other style carton commonly used to package fresh produce.
- the lid 5 is constructed of a semi rigid to rigid polymeric material such as polyvinyl chloride, polypropylene or polyethylene and is sized to fit over the corrugated carton and conform to the vertical edges of the side walls.
- the lid 5 includes a rim 20 that extends downward sufficiently to cover downward facing concavities incorporated into the vertical sidewalls of the carton common to Bliss or other style packaging.
- the thickness of the lid 5 may be varied to obtain the desired structural strength for stacking and having a general range of 0.25 mm to about 2.0 mm.
- the inner surface of the lid may be treated with an anti-fog coating or film to limit condensation from developing on the interior surface which would limit the ability to observe the contents of the carton.
- the carton 10 is constructed of corrugated fiberboard and may include a selective permeable membrane or active oxygen scavenging polymer incorporated into its construction.
- the carton 10 includes four vertical side walls perpendicularly joined to a fiberboard bottom forming a regular polygon in the shape of either a square or rectangular box.
- the carton is intended to have a standard footprint (dimensions) of 40 cm x 60 cm but other dimensions such as 40 cm x 30 cm are envisioned as well.
- the top of the carton is open, allowing unrestricted access to an interior storage volume defined by the vertical sidewalls and bottom.
- the vertical height of the sidewalls is variable, typically in the range of 10cm - 30cm, and largely dependent on the desired packing density of the produce to be placed within the carton.
- the produce should be placed so as to reach a height equal to or below that of the lowest open top edge of the vertical sidewalls.
- the permeability of the selective membrane is chosen based on the respiratory nature of the produce to be contained within the packaging.
- FIG. 2 a side view of a long dimension of the modified atmosphere packaging system is shown where the lid 5 includes a selliform profile to conform to the vertical top edges of the carton 10.
- the downward facing edge 20 of the lid 5 is sealingly attached to the carton 10 using sealing packing tape 30.
- the raised stacking structures 15 are shown with a generally planar exterior surface which is substantially parallel to the exterior surface of the lid 5.
- the grooves 25 are intended to mate with grooves 75 included in the carton 10 which allows the lid to 5 to lie flush with the vertical edges of the carton.
- the dashed line indicates the end of the downward facing rim 20 which is covered by the sealing tape 30.
- the downward facing rim 20 extends vertically downward along the exterior surface of the four vertical sidewalls sufficiently to fully enclose any exposed concavities associated with the vertical sidewalls and allow adequate contact surfaces for application of the packing tape at an interface where the end of the rim and exposed portion of the vertical sidewalls of the carton occur.
- the sealing tape 30 may be used as a product tampering indicator or another seal may be placed over the tape 30.
- FIGs. 3A and 3B an alternate embodiment of the invention is shown where one or more apertures 35a, 35b, 35c are provided in one or more surfaces such as the lid, one or more vertical sidewalls or the bottom of the carton.
- the apertures fully penetrate the lid, sidewalls and/or bottom of the carton such that external ambient air is in contiguous contact with the interior storage volume of the carton.
- One or more selective permeable membranes in the form of adhesive patches 40a, 40b are applied over the apertures and adhered to the lid 5 and/or vertical sidewall of the carton 10 to establish a modified atmosphere within the interior storage volume of the carton.
