Embodiments of the present disclosure generally relate to packaging systems. In particular, embodiments of the present disclosure relate to a packaging system for containing, storing, displaying, and shipping produce items, such as strawberries.
An important part of a well-balanced diet comprises the consumption of fresh fruits and vegetables. Despite highly advanced storage and transportation systems, the delivery of superior quality agricultural produce still remains a challenge. Often times, the process of harvesting a fruit (or vegetable) from its initial growing location, and safe delivery of the fruit (or vegetable) to its destination encompasses thousands of miles, and includes journeys that traverse many climates and difficult terrain. The negative consequences of such challenging transport are particularly pronounced when the produce being transported consists of soft or delicate fruit such as berries, cherries, plums, peaches, apricots, grapes and other fruit that can be easily bruised. Often times, farmers are forced to picked fruit early, so that it is harder, and more likely to make it to its destination intact. By prematurely harvesting fruits and vegetables, and depriving them of the opportunity to ripen while still growing, flavor and taste are compromised.
Therefore, there is a need in the art for a new and improved packaging system that can be used in containing, shipping, transporting, and storing in a cooled environment produce items that easily can be damaged and/or bruised, such as strawberries. There is a further need in the art for a new and improved packaging system that allow for more rapid and uniform cooling after harvest to remove field and product heat, slowing respiration and providing a longer shelf life.
A packaging system for produce is described. The packaging system is useful for all types of produce and especially useful for soft fruit including but not limited to berries, cherries, plums, peaches, apricots, grapes and other fruit that can be easily bruised.

Referring to
The base portion 13 includes a bottom 36 and four beveled edges 15 that extend from the perimeter of the bottom 36. Sidewalls 16 extend from the beveled edges 15 to form a compartment 15 in the base portion 13 to place strawberries and other produce items. The bottom 36 includes a raised bed 37, which helps prevent and/or minimize bruising of the strawberries and other produce items. The beveled edges 15 includes a plurality of recessed vents 17, which makes it possible to increase the cooling air that travels into the container 11 and improve the cooling mechanism. The recessed vents 17 of the base portion 13 further ensure that condensation and moisture do not build up within the container 11 and any produced water can freely drain through the recessed vents 17.
In some embodiments, the bottom 36, beveled edges 15, and sidewalls 16 form a generally rectangular compartment. The beveled edges 15 include two short beveled edges 18 and two long beveled edges 19. The short beveled edges 21 can include two to four recessed vents 17 and the long beveled edges 19 can include six to ten recessed vents 17. Preferably, the two short beveled edges 18 each include three recessed vents 17 and the long beveled edges 19 each include eight recessed vents 17. The recessed vents 17 preferably are in the shape of a slot configured to have an overall elongated oval or rectangular shape. The recessed vents 17 are positioned on the beveled edges 15 so that they do not contact the container contents, which may cause the contents to be sliced, cut, and/or bruised.
The top lid 12 also includes four beveled edges 20, preferably two short beveled edges 21 and two long beveled edges 22. The beveled edges 20 are integral with a cover 23. The cover 23 is preferably flat to allow for stacking of multiple containers 11. In some embodiments, the short beveled edges 21 can include two to four recessed vents 17 and the long beveled edges 22 can include six to ten recessed vents 17. Preferably, the two short beveled edges 21 each include three recessed vents 17 and the long beveled edges 22 each include eight recessed vents 17. The recessed vents 17 makes it possible to increase the cooling air that travels into the container 11 and improve the cooling mechanism. In addition, the recessed vents 17 are positioned on the beveled edges 20 so that they do not contact the container contents, which may cause the contents to be sliced, cut, and/or bruised. The recessed vents 17 of the top lid 12 further ensure that condensation and moisture do not build up within the container 11.
Preferably, the cover 23 is rectangular in shape and includes four corners 24. The cover 23 can include a plurality of vent holes 25. In some embodiments, the cover 23 includes a vent hole 25 disposed in the vicinity of the corners 25 of the cover 23. The vent holes 25 of the cover 23 further ensure that condensation and moisture do not build up within the container 11. In some embodiments, the cover 23 can further include protrusions 26. The protrusions 26 align with the outer perimeter 26 of the raised bed 37 of the base portion 13 of a second container, which allows for the second container to be stacked on the container 11 more securely. As shown in
In some embodiments, the top lid 12 is removably attached to the base portion 13 by button locks 28. For some embodiments, male button locks 29 are disposed on an interior surface 30 of the top lid 12. Preferably, two male button locks 29 can be disposed at the far corners 31 of the interior surface 30 away from the spine 14 that pivotably attaches the top lid 12 to the base portion 13.
An upper surface 32 of the base portion 13 can include female button locks 33 configured to correspond with the male button locks 29. Preferably, two female button locks 33 can be disposed at the far corners 34 of the upper surface 32 of the base portion 13 away from the spine 14 that pivotably attaches the top lid 12 to the base portion 13.
The upper surface 33 of the base portion 13 can further include edge support bars 35. The edge support bars 35 are configured to be placed into contact with the interior surface 30 of the top lid 12 when the top lid 12 is removably attached to the bottom portion 13 in a closed state. By being placed into contact with the interior surface 30 of the top lid 12, the container can include windows 38 between the top lid 12 and the base portion 13 in the closed state. The windows 38 allow for flow of continuous cooling air providing an efficient cooling effect to the produce items within the container 11, such as strawberries. The windows 38 further ensure that condensation and moisture do not build up within the container 11
Preferably, the upper surface 33 includes three edge support bars 35 that extend along the side walls 16 of the base portion 13. That is, there is one edge support bar 35 on the upper surface 33 extending along each side wall 16 of the base portion 13, except for the side wall 16 that extends along the spine 14. As seen in
Though not wishing to be bound by the following theory, specialized venting as discussed in the present disclosure enables optimization of air flow and evaporation of moisture, as well as reduction of condensation and respiration. The containers 11 also minimize contact between individual so that that the occurrence of bruising, squashing, and other damage is limited.
In some embodiments, the container 11 is a 16 oz. container for 12-18 strawberries provided in one layer. Consumers gain a greater level of confidence in purchasing the strawberries contained in the container 11 over conventional containers because they can see every strawberry in the container 11. Conventional containers for most fruits including strawberries do not permit consumers to view each individual fruit and rotting and/or bruised fruits are embedded in the middle and hidden from view
In an open state (where the top lid 12 is not attached to the base portion 13), the container 11 can form a rectangular shape having a dimension of 10.91 inches by 9.35 inches. In a closed state (where the top lid 12 is attached to the base portion 13), the container 11 can have an internal height of 1.73 inches. The vents 11 can have a length of 0.44 inches and a width of 0.19 inches. The windows 38 can have an opening of 0.22 inches between the top lid 12 and the base portion 13. For some embodiments, two containers 11 that are stacked on one another would have an overall stack height of 3.92 inches.
The skilled artisan will readily understand and appreciate that the mentioned sizes of the dimension of the individual containers are not solely limited to these values, as they are merely shown as examples of an embodiment of the present disclosure. Thus, the container 11 can also have longer or shorter longitudinal lengths, as well as longer or shorter widths, as long as the key structure features are preserved. The container can also be heavier or lighter than 16 oz.
As best seen in
To prevent any potential bruising of the produce items contained in the containers 11, the box 50 is configured to store the containers 11 within the cavity 52 such that the containers 11 are flush against the inner walls 53 of the box 50 forming the cavity 52. In this way, there is minimal movement of the containers 11 during transport of the produce items.
In some embodiments, the four sidewalls 54 include two short sidewalls 55 and two long sidewalls 56. The short side walls 55 include a plurality of slots 57. Preferably, the slots 57 are configured such that there is an upper row 58 of slots 57, a middle row 59 of slots 57, and a lower row 60 of slots 57. More preferably, the slots 57 are centrally located on the two short side walls 55. The upper row 58 preferably has two slots 57 separated by a tab 61. Such configuration aligns the windows 38 and vents 17 of the upper layer of containers 11 with the slots 57 for improved sheetline venting. In addition, the configuration with two slots 57 separated by a tab 61 streamlines cooling air that travels into the container 11 and improves the cooling mechanism during a precooling process.
The middle row 59 preferably also has two slots 57. The middle row 59 of slots 57 align with the windows 38 and vents 17 of the lower layer of containers and the recessed vents 17 of the base portion 13 of the containers 11 of an upper layer stacked on the lower layer of containers. Such configuration aligns the windows 38 and/or vents 17 of the upper and lower layers of containers with the slots 57 of the box 50 for improved sheetline venting. The middle row 59 of two slots 57 also streamlines cooling air that travels into the container 11 and improves the cooling mechanism during a precooling process.
The lower row 60 preferably has two slots 57. The lower row 60 of slots 57 align with the recessed vents 17 of the base portion 13 of the containers 11 of the lower layer of containers llfor improved sheetline venting. This configuration further streamlines cooling air that travels into the container 11 and improves the cooling mechanism during a precooling process.
As best seen in
The packaging system 10 is particularly suited for hydroponically farmed strawberries. One reason for this is that hydroponically farmed strawberries are picked by pickers in a standing position. The strawberries are picked, and directly placed in the containers 11. The packaging system 10 provided enables the transportation of just-picked strawberries to pre-cooling facilities in a rapid fashion compared to traditional picking and packing. By arriving quickly to the pre-cooling facility, the strawberries reach a point of stasis (akin to hibernation) in an accelerated fashion thereby maximizing quality as discussed above.
Although described in connection with these embodiments, those of skill in the art will recognize that changes can be made in form and detail without departing from the spirit and scope of the disclosure.
