[0005] Prior to this invention, the industry-standard method for packaging bananas for shipment to North American retailers has been to pack in corrugated cardboard boxes that have been tailored to this application. Corrugated boxes for bananas are a 2-piece construction with outside dimensions of about 19.7" (50 cm) x 15.75" (40 cm) x 9.69" (24.6 cm) in height weighing 3 lbs. each. These boxes maximize the available space by fitting 2 boxes across the 40" dimension of the pallet and 3 boxes across the 48" dimension of the pallet for a total of 6 boxes per layer stacked 8 layers high on the pallet. The 2-piece box consists of a bottom box and a top cover that telescopes the full height of the box to contribute to stacking strength with double wall construction. In order to deliver 40 lbs. net weight of =
bananas, corrugated boxes are packed with about 41.5 lbs. of green fruit at the farms. Corrugated boxes weigh approximately 3 lbs. each, resulting in container loads that approach both the weight limit and the cubic space or cube limit of containers.

[0006] Bananas are cut from stems into clusters of 4 to 9 banana fingers;
each cluster having 2 rows of bananas referred to as the inner whirl on the concave ' side of the cluster and the outer whirl on the convex side of the cluster.
Boxes are typically packed with 15 to 17 clusters per box to meet the net weight specification for major North American retailers. These clusters are packed in 4 lines or rows of fruit, crowns and inner whirl down, with each line containing 4 to 5 clusters across the longer 19.7" dimension of the box. The first 2 lines are packed overlapping in the center of the box with the 2 additional lines of fruit packed left and right overlapping the first two lines AMENDED SHEET -IPEA/US

The telescoping lid faciiitates this high pack while still permitting boxes to be stacked on pallets. 41.5 lbs. of green fruit also cause flexible boxes to bulge in all directions. Due to the initial high pack situation with 4 lines of fruit combined with the tendency for bottoms to sag, stacking load is transferred directly through the bananas and ultimately shared between the bananas and the structure of the corrugated box.
This stacking bad on the bananas causes various forms of damage to the bananas including damage to crowns, feeder lines (necks), latex staining, point scaring and high pack damage.
[0008] To maximize stacking and handling strength of corrugated cardboard boxes, ventilation is very limited, making it more difficult to control the atmosphere around the bananas during cooling and ripening. The insulation value of 2 or more layers of corrugated also adds to difficulty of controlling the temperature of bananas during the ripening process, [0009] Problems associated with this present method include:

4 packed in corrugated boxes due to lack of ventilation and insulation value of the corrugated boxes. Bananas are ripened in boxes placed in a ripening chamber or ripening room, where control of the temperature and atmosphere around the bananas is critical to optimum ripening.
[00010] in the past, attempts to duplicate the dimensions of the corrugated box with a more rigid, 5-sided, open top Reusable Plastic Containers (RPCs) have proven to be unsuccessful in shipping bananas. RPCs with covers, like corrugated banana boxes, have proven to be costly, inefficient and weight prohibitive. Rigid RPCs with 4 walls and a base are designed to handle ail stacking load transferred through the was and base of containers to the pallet with a safety margin to achieve many years of life.
RPCs further rely on interlocking geometry of about .250" in of depth to prevent RPCs from shifting on pallets between layers. When RPCs are high packed, as in the case of a 4-line banana pack in an RPC of about 19.7" (50 cm) x 15,75" (40 cm) x 9.69"
(24.6 cm) in height, the base of the top RPC in a stack may not come in contact with the was of the RPC below, preventing proper stacking and interlocking. The rigid nature of the RPC, along with the lack of a telescoping cover to protect the fruit, also exacerbates hard pack damage associated with high pack. This common 6-down, 8 high banana box configuration does not successfully translate from corrugated to RPC
construction.
[00011] In the past, attempts have also been made to solve these problems using conventional RPCs that are othenivise used successfully to transport to many other produce items to North American retailers. Conventional RPCs have a footprint of about 23.5" (60 cm) x 15.75" (40 cm). This footprint utilizes the footprint of 48" x 40"
GMA pallet with a row of 3 RPCs lined up with the narrow RPC dimension of 15.75"
across the 48" dimension of the pallet on one edge and a row of 2 RPCs turned perpendicular to the first row with the longer 23.5" dimension across the 48"
dimension of the pallet. This is referred to as a 5-down footprint.
[000121 Conventional RPCs can be packed with 3 lines of fruit to achieve the 41.5 lbs. green fruit target due to the greater length of the container of 23.5"
vs. the length of corrugated boxes of 19.7, however the reduced number of containers per layer on the pallet of 5 vs. 6 dramatically reduces the quantity of bananas per pallet bad.
This issue has been somewhat mitigated by reducing the height of the RPC from 9.65" with the corrugated to about 9.22 in order for containers to be stacked 9 high on a pallet, by taking advantage of the reduced height of a 3 line pack, while introducing increased risk of high pack damage. However, this configuration still results in 6,25% less fruit per pallet load with only 45 (5 per layer, 9 high) containers per pallet bad in comparison to 48 (6 per layer 8 high) containers per pallet bad with corrugated. This loss in volume efficiency manifests itself as a gap in the center top of the RPC between the top 2 lines of fruit, since the RPC is just as wide as the corrugated box, but with one less line of fruit. Furthermore, conventional RPCs of these dimensions weigh about 4 bs., reducing the net payload of bananas even in traders with larger volurne capacity when compared with bananas in 3 lb. corrugated boxes.
[00013] Such efforts have not been successful in the North American market to date due to problems associated with using conventional RPCs with bananas, including:
Conventional RPCs hold fewer bananas per pallet load than corrugated boxes due to only five (5) containers per layer fitting on a pallet versus six (6) containers per layer, increasing freight cost, ^ Optimum ventilation across the about 40" dimension of the pallet cannot be achieved with conventional RPCs due to the perpendicular pattern of pallet loading.
= Optimization of RPC height to maximize pallet density results in "high packs" that can cause damage to the banana at the top of a container by the container above.
= Rigid RPC was can also cause damage to bananas relative to more flexible corrugated was.
= No reusable means for easy sampling of fruit without de-stacking the RPCs.
= Conventional RPCs cannot duplicate the net payload achieved with corrugated banana boxes even in larger over the road traders due to the greater tare weight of the container of 4 lbs. vs. 3 lbs, for corrugated.
SUMMARY
[00014] A novel design for a container has been developed that possesses advantageous properties and functionality. For example, the container can solve problems associated with conventional corrugated banana boxes, RPCs with the dimensions of conventional boxes and conventional RPCs with a 5-down footprint. The novel design can provide a more economical system for packing, cooling, shipping, ripening and merchandising bananas (and possibly other fruits, vegetables and produce items) that can improve food quality and reduce environmental impact.
[00015] Exemplary embodiments of the novel design can include one or more of these features:
[00016] New 6-Down Footprint ¨ An exemplary container can incorporate a reverse pallet loading pattern with three (3) containers across the approximately 40-inch dimension of the pallet and two (2) containers across the approximately 48-inch dimension. This pattern is achieved with dimensions of about 24" (60.96 cm) x13.33"
(33.87 cm). This is in contrast to the corrugated loading pattern with two (2) containers across the about 40-inch dimension and three (3) across the about 48-inch dimension.
This footprint factates packing of three (3) longer ones of fruit per container versus four (4) shorter ones in a corrugated box. Three (3) lines pile a maximum of 2 dusters or 4 banana fingers high with one line on the bottom of the RPC, one line on the top left and one line on the top right extending across the longer 24" dimension of the RPCs. This is in comparison with the 4 line corrugated pack where lines are piled up to 3 dusters high . .

that is the same height as the corrugated box of about 9.65". This lower pack height also facilitates the interlocking stacking of one open top RPC on top of the walls of another open top RPC not achieved with RPCs of the same dimension as corrugated boxes.
= =
[00017] The narrower about 13.33" (33.87 cm) dimension of the new RPC
optimizes the width of the RPC for a 3 line pack thus eliminating the open channel in the top center of a 3 line pack in a wider 15.75" (40 cm) 5-down RPC.
[00018] Further advantages of the new reverse 6-down footprint include exposure of all 3 lines of fruit in each RPC to forced air in ripening chambers in contrast to 4 line packs in corrugated boxes where the 2nd line of fruit is totally encapsulated in the other 3 lines.
- [00019] Increased Ventilation -The new pallet loading pattern, combined with the high-strength plastic construction also facilitates much greater ventilation across.
the top and/or bottom of each row of fruit or produce. The vent holes of the container are substantially greater than the size of the vent holes provided in conventional corrugated or RPC containers. The vent area for the container may be about two times greater, about three times greater, about four times greater or about five times greater than the ventilation provided in a conventional corrugated or RPC
container.
. This allows for increased ventilation. The greater ventilation can be about two times =
greater, about three times greater. about four times greater or about five times = greater than the ventilation provided in a conventional corrugated or RFC
container.
This is in sharp contrast to the pattern found in corrugated packs, where minimal Ventilation, is permissible and one of the four lines is almost completely insulated .
from ventilation. Greater ventilation translates into better cooling, temperature management, ripening control, 'quality and shelflife for the produce in the container.
This new pattern also solves the problems of conventional RPCs, permitting (1) = equal container load volume =

all airflow is forced in ripening chambers. The new pallet loading pattern allows the =
ventilation holes to line up consistently through all containers, there are reduced opening and channels for escape of forced air (often used in the ripening process), and =
this results in improved temperature management capabilities.
(00020] Greater Container Length and/or Width When Set Up Than When Folded Down -It is highly desirable to have the maximum .possible length and/or width of crates or boxes without those crates or boxes overhanging the pallets on which they rest. This allows the proper use of corner boards and straps to secure the crates in storage and transport. In the case of exemplary embodiments of the new crate design, this optimum length is about 24 inches (about 60.9 cm). However, the crates will be used in the North American retail. supply chain where they will often be mixed with conventional = RPCs that are only about 23.5 inches (60 cm) in length. Therefore, it is desirable for the new crates to be about 24 inches long when set up and filled with fruit or produce, but only about 23.5 inches long when folded down to facilitate mixing of empty folded =
crates on pallets. This is accomplished by a unique and novel design approach that not only accomplishes increased length and/or width when set up, but also does so without.
increasing the height of folded crates to optimize return freight. The full approximately 24-inch length in the set-up mode maximizes fruit (e.g., banana) or produce capacity and eliminates pallet underhang of crates that exist with other RPCs. This facilitates =
proper use of corner boards and prevents or substantially limits the flow of air between =
= . pallet loads in ripening rooms, to enhance ripening control.
(000211 Fruit Sampling -It is often desirable to randomly sample a fruit while it is in = boxes or crates that are often stacked eight (8) layers high in ripening rooms.

Corrugated boxes are cut open for sampling, using a knife. This procedure can damage fruit unnecessarily, and weakens the box, potentially contributing to further box failure and fruit damage, Conventional RPCs have no non-destructive means for fruit sampling when crates are stacked. The new crate has a unique and novel sample door to provide fruit graders access to fruit in every crate on a pallet without de-stacking. This access door can be opened and closed repeatedly throughout the life of the crate without affecting the structural integrity of the crate, the protection of the fruit (e.g,, bananas) or produce in the crate, or the life of the crate. The sample door may be contoured to match the contour of the wall in which the sample door is in, flexible to provide cushioning to the contents and to prevent damage, and tight-fitting so as not to create edges and gaps which could damage the contents [00022] Maximum Interior Volume ¨ Exemplary embodiments of the crate can incorporate several additional features to maximize the internal volume of the crate and minimize damage to bananas. The floor of crates can be substantially flat and smooth monolithic sheets of plastic. This can maximize internal height and minimize damage to fruit (e.g., bananas) or produce in a crate from the crate above, Conventional RPCs incorporate features which project from a crate down into the crate below for interlocking and stacking. Exemplary embodiments of our crate can interlock with features that project up from the top of crate walls only. Interior walls are also curved outward to the maximum dimensions to maximize internal volume, with all structure located on the perimeter of walls away from the curved fruit or produce. This construction also makes walls more flexible, smooth, curved and compliant where they are contacted by the fruit (e.g., bananas) or produce, further minimizing fruit or produce damage.
[00023] Lead-in for Stacking ¨ Conventional RPCs provide interlocking stacking, but no lead-in, so that crates have to be perfectly aligned in length and width for proper stacking. Without such perfect alignment, a conventional RPC crate corner may drop down into the crate below and damage fruit or produce. Exemplary embodiments of our crate's unique design include about 1/8 inch to about 1/2 inch of lead-in in both the length and width dimensions for easier stacking. Exemplary crates can also be slid in and out of place for easier stacking and de-stacking.
[00024] Latching of Sidewalis ¨ Conventional RPCs that are collapsible by folding are often designed to take on their set-up configuration by latching of their end wails. in contrast, exemplary embodiments of our crate's unique design employ latching of the sidewalls.
[00025] Thus, according to one aspect, an exernplaiy RPC provides a "collapsed"
configuration or an "erected" configuration comprised of a base, capable of being coupled or attached to a plurality of sidewails and a plurality of endvvails.
The RPC can further include two sidewails, each sidewall coupled or attached to the base so as to be movable between an upright position when the container is in an "erected"
position and a folded-down position when the container is in a "collapsed" position. The RPC can further include two endwalls, each endwall coupled to the base so as to be movable between an upright position when the container is an "erected" position and a folded-down position when the container is in a "collapsed" position. The RPC can further include an opening in each endwall for use as a handle for the container. The RPC can further include one or more latches on each endwall, each configured to couple an endwall to a sidewall when the container is in the "erected" configuration.
The RPC can further include one or more stops on each sidewall, each stop corresponding to a latch and configured to be in contact with that latch when the container is in the "erected"
configuration.
[00026] in an exempiary embodiment, the arrangement of plastic or resin shipping containers for shipping or storing bananas includes six shipping containers arranged on a top surface of a standard 48"-by-40" pallet, with three of the containers arranged across the 40" dimension of the pallet and two containers arranged across the 48"
dimension of the pallet. The arrangement provides three lines of bananas within each container compared to four shorter lines of bananas provided in a conventionai corrugated cardboard box. By providing three lines of bananas within each container, the bananas in the containers of the arrangement do not pile as high as the bananas in a conventional corrugated cardboard box, which results in less "high pack"
damage to the bananas in the containers of the arrangement when compared with bananas provided in the conventional corrugated cardboard box.
[00027] In an exemplary embodiment, the arrangement of plastic or resin shipping containers for shipping or storing bananas and providing enhanced ventilation to the bananas in the containers includes two or more containers arranged on a top surface of a standard 40"-by-48" pallet, In this arrangement, each container has two endwalls and two sidewalls and a plurality of vent holes in each of the sidewalls or endwalls. At least one container is arranged across the 40-inch dimension of the pallet and at least one other container is arranged across the 48-inch dimension of the pallet, so that the plurality of vent holes in the container sidewalls or endwalls completely or substantially align, providing enhanced ventilation to the bananas in the containers resulting from airflow passing through the pallet load in only one direction through the plurality of vent holes in the container sidewalls or endwalls.

[00032] An exemplary embodiment is depicted in FIG. 1 as a collapsible container for the storage and transport of produce. The container 10 as fully erected includes a base 13 that extends in a horizontal plane, two endwalls 11 that extend in respective vertical planes, and two sidewails 12 that extend in respective vertical planes.
[000331 The container 10 is molded from a plastic or resin material, such as, for example, polypropylene, a resin or thermoplastic polymer or combination thereof.
Suitable materials can include resins, plastics or themioplasfics including, but not limited to, polyethylene, polypropylene, polyvinyl chloride, polyurethane, polyester, epoxy resin, phenolic resin, polystyrene, polycarbonate, combinations thereof and the like. The container 10 has a construction that is designed to be strong relative to its weight. The material of the container allows it to be rigid enough to maintain its structural form when erected for storage or transportation, thereby protecting the produce it contains. At the same time, the material of the base 13, endwalls 11, and sidewalls 12 of the container 10 are flexible enough to minimize damage to the contents of the container, [00034] The interior of the container 10 is primarily defined by the base 13, sidewalis 12 and endwalls 11. A handle 15 is located near the top center of each endwall 11. The base 13 is preferably a flat and smooth monolithic sheet of plastic.
This maximizes internal height and minimizes damage to produce on the top of the container due to contact from the container above. The shape of the endwalls 11, sidewalls 12, and base 13 are designed to reduce bruising conditions for the contents of the container. There are expansive, recessed areas (30, 31) in the endwalls and sidewalls. Much of the structure of the container, including hinges 45, stops 22, and latches 20 (each of which will be detailed below), is designed to be located on the perimeter of the was away from the curved contents of the container.
Preferably, the container has features for interlocking with other containers that project up from the top of container was. The endwalls 11 and sidewails 12 are preferably curved outward to maxirnize internal volume, and are constructed to be flexible, smooth, curved and compliant to minimize damage due to contact with the contents of the container.
[00035] Because the container is designed to hold produce that may be purposely ripened while in the container, the container has various ventilation holes 14 along its sidewails 12 and base 13, which allow for forced air to travel to the produce while packed in the container. FIG. 3 depicts the intended airflow pattern through a plurality of containers of an exemplary embodiment that are stacked in a multi-layer "six-down"
configuration. The placement of the ventilation holes 14 is designed to permit substantial alignment of the ventilation holes 14 of several containers when stacked on a pallet, which is a typical arrangement of the containers when filled with produce that are subject to ripening by forced air in a ripening room or ripening chamber.
This alignment creates a pathway for the forced aft to easily reach produce that is stacked in the containers throughout the pallet, [00036] The endwalls 11 and sidewalls 12 of the container can be connected to the base 13 through the use of a plurality of hinges 45 or other movable couplings. HG.
7 depicts the hinges 45 on the sidewall, The hinges 45 will permit the endwalls 11 and sidewalls 12 to be folded down toward the base 13 when the container is in the "coliapsed" configuration, and the hinges 45 will allow the endwalis 11 and sidewalls 12 to be moved to an upright position when the container is in the "erected"
configuration.
In changing the container from the "erected" configuration to the "collapsed"
configuration, the first sidewall 12 will be folded down over the base 13, then the second sidewail 12 will be folded down toward the base 13 and will overlap part of the first sidewall 12. Next, the two endwalls 11 will be folded down toward the base 13 and over the sidewalls 12, This "collapsed" configurafion results in the container being made much more compact than when in the "erected configuration." The relatively flat, compact container in the "collapsed" configuration can be easily transported for reuse.
When in the "collapsed" configuration, many of the containers can be stacked for easy transport and/or storage.
[00037] From the "collapsed" or "folded down" configuration, the container can be changed into the "erected" configuration by first unfolding the endwaHs 11 and raising each of them to an upright position. Then, one sidewall 12 is raised and is coupled to the two endwalls 11. Finally, the second sidewali 12 is raised and is coupled to the two endwalls 11.
[00038] Several features of an exemplary embodiment of the container can aid in assembly, specifically the transition of the container from a "collapsed"
configuration to an "erected" configuration. Some of these are shown in FIG. 4 and HG. 5. An exemplary embodiment uses a latch 20 and stop 22 to couple the sidewall 12 to the endwall 11. When the inside edge 23 of the sidewall passes the latch 20, the latch 20 springs back into position and hits a stop 22 on the sidewall 12. This contact between the latch 20 and stop 22 can result in a clicking sound that helps the user know that the latch 20 has engaged the stop 22 and that the endwali 11 and sidewall 12 are thereby coupled. The latch 20 can be flexed or otherwise actuated to enable it to first become displaced while the edge of the sidewall 12 contacts it and passes by it, but then spring back to engage the stop 22 on the sidewall 12.
[00039] In an exemplary embodiment, the edges of each endwall 11 and sidewall 12 include a series of vertically-spaced "I.." or "L-shaped hooks 50 that allow an endwail 11 to interlock with a sidewall 12 when both are upright and overlap when the container is in the "erected" position. This further promotes dose coupling of the endwails 11 to the sidewalls 12, promoting the structural integrity of the container 10 in the "erected"
configuration and thereby reducing damage to the contents of the container.
[00040] While many conventional RPCs are collapsible by folding, they are often designed to take on their set-up configuration by latching of their end was.
Such endwall latching can result in inadvertent disengagement of the /atches (and resulting col/apse of the RPC) during carrying and stacking due to the exertion of lateral forces against the handles or end was. This can result in damage to the contents of the container. As indicated above, an exemplary embodiment of the container has a unique design that employs latching of the sidewalls 12, which reduces inadvertent disengagement, since lateral force against the handles and end was during carrying and stacking will not disengage the latches. In addition, the use of "L" hooks 50 to couple each sidewaH 12 to each endwall 11 will further counteract any lateral forces on the handles and endwalls. FIG. 8 depicts a cross section of a sidewall 12 and endwall 11 when coupled through the use of "L" hooks 50.
[00041] In an exemplary embodiment, one or more of the sidewalls 12 or endwalls 11 will have an opening within which a door 40 is mounted in such a way that does not cut through the perimeter of the sidewall 12 or endwall 11. Such door 40, which can be constructed from the same material as the sidewall 12 or endwall 11, can be hingeably mounted or attached to the opening to allow the door 40 to pivot and be opened and closed. Opening the door 40 permits visual inspection and/or sampling of the product in the container 10, even when the container is within a stack of other containers on a pallet. The door 40 can be closed again, renewing the protective barrier that the endwall 11 or sidewall 12 provides to the contents of the container 10 in storage or transport. Preferably, when the door 40 is in the closed position, the door 40 is coupled or attached to the sidewall 12 or endwall 11 by a clip 41 that prevents the door 40 from opening without user action.
[00042] FIG. 7 and FIG. 7a depict an exemplary embodiment with the opening and door 40 in the sidewall, and the clip 41 having the form of a spring tang.
This embodiment of the curved fruit sampling door 40 incorporates a clip 41 that, when engaged, holds the door 40 closed and when disengaged allows the door 40 to open to provide access to the contents of the container 10. Preferably, the clip 41 is a "low profile spring tang" mechanism which fits within the thickness of the sidewall 12 or endwall 11, not extending inside the curved surface of the sidewall 12 or endwall 11 or outside the plane as defined by the outside surface of the sidewall 12 or endwall 11.
The mechanism of the clip 41 is reusable, allowing for repeated opening and closing of the sample door 40. The clip 41 is rotated outward to disengage the clip 41 and allow the door 40 to open. The door 40 and clip 41 are rotated inward with slight pressure to engage the clip 41 and the latch bracket 42. Because of the door's 40 material, its hinged connection 47 and the use of the clip 41 to secure it, the door 40 can be opened and dosed repeatedly throughout the life of the container 10 without affecting the structural integrity of the container, the protection of the product in the container, or the life of the container.
[00043] In a preferred embodiment, the dimensions of the container 10 are optirnized for use in a particular product market or supply chain. It is desirable to have the maximum possible length of a container 10 without overhanging the pallets on which a container or multiple containers are placed. In the case of an exemplary embodiment of the container for use with bananas, where 40-inch by 48-inch pallets are customarily used, the optimum exterior length for a container 10 is about 24 inches (about 60.9 cm) and the optimum exterior width is about 13.33 inches (about 33.9 cm). With these dimensions, the container 10 could be placed on pallets in a six-down configuration, a pallet loading pattern with three (3) containers across the approximately 40-inch dimension of the pallet and two (2) containers across the approximately 48-inch dimension. See FIG. 2 and FIG. 3 for illustrations of a "six-down"
configuration.
[00044] In the North American retail supply chain, containers are likely to be mixed with conventional RPCs that are only about 23.5 inches (about 60 cm) in exterior length.
Accordingly, it is desirable for the container 10 to be about 24 inches long when erected and filled with bananas, but only about 23.5 inches long when folded down to factate mixing of empty folded crates on pallets. The novel design approach accomplishes the increased length when erected, but does so without increasing the height of foided containers 10 to optimize the number of containers 10 that can be packed on pallets for return. FIG. 10a depicts the profile of one end of the container when in the "collapsed"
configuration. Fig, 10b depicts the profile of the same end of the container when in the "erected" configuration, showing the additional length of the container in the "erected"
configuration when compared to the length of the container in the "collapsed"
configuration, The approximately 24-inch iength when erected maximizes banana capacity and eliminates pallet underhang that exists with other RPCs. These dimensions also dose gaps between pallets for better transport stability and airflow.
This brings the added benefit that corner boards can be properly used to prevent the flow of air between pallet loads in ripening rooms, so that ripening can be more precisely controlled.
[00045] In a preferred embodiment, a container 10 with an exterior measuring approximately 24 inches long by approximately 13.33 inches wide results in interior dimensions that facilitate packing of three (3) longer lines of curved fruit (e.g., bananas) per container. Three (3) lines don't pile as tall as the four-line arrangement commonly used in conventional banana containers, and this lower packing height results in less "high pack" damage to the banana in the container. Fla 9a depicts the first line of packing of bananas. FIG. 9b depicts the second line of bananas packed over the first line, partially overlapping it. Finally, FIG. 9c depicts the third line of bananas packed, which also partially overlaps the first line. A preferred embodiment also includes added height to the container 10 to prevent "high pack" damage, with the preferred exterior height for a container for bananas being approximately 9,66 inches.
[00046] I n a preferred embodiment, the container 10 includes some extra material 60 in its dimensions to promote easier stacking without the need for perfect alignment.
in an exemplary embodiment, this lead-in material 60 includes about 1/8 inch to 1/2 inch lead-in in both the length and width dimensions for easier stacking. Exemplary containers can also be slid in and out of place for easier stacking and de-stacking as a result of this lead-in material.
[00047] In another embodiment, the endwalls 12 and sidewalls 11 are optimized for the storage of transportation of pineapples, specifically through the use of wall shaping and recessed areas designed to protect the barrels and crowns of pineapples, and the abty to adjust the height of the container 10 at the time of packing to closely fit the pineapples in the container.
[00048] While the application has been described in terms of various specific and preferred embodiments, the skilled artisan will appreciate that various modifications, substitutions, omissions, and changes may be made without departing from the spirit thereof. Accordingly, it is intended that the scope of the present application be limited soiely by the scope of the following claims, including equivalents thereof.
[00010] in the past, attempts to duplicate the dimensions of the corrugated box with a more rigid, 5-sided, open top Reusable Plastic Containers (RPCs) have proven to be unsuccessful in shipping bananas. RPCs with covers, like corrugated banana boxes, have proven to be costly, inefficient and weight prohibitive. Rigid RPCs with 4 walls and a base are designed to handle ail stacking load transferred through the was and base of containers to the pallet with a safety margin to achieve many years of life.
RPCs further rely on interlocking geometry of about .250" in of depth to prevent RPCs from shifting on pallets between layers. When RPCs are high packed, as in the case of a 4-line banana pack in an RPC of about 19.7" (50 cm) x 15,75" (40 cm) x 9.69"
(24.6 cm) in height, the base of the top RPC in a stack may not come in contact with the was of the RPC below, preventing proper stacking and interlocking. The rigid nature of the RPC, along with the lack of a telescoping cover to protect the fruit, also exacerbates hard pack damage associated with high pack. This common 6-down, 8 high banana box configuration does not successfully translate from corrugated to RPC
construction.
[00011] In the past, attempts have also been made to solve these problems using conventional RPCs that are othenivise used successfully to transport to many other produce items to North American retailers. Conventional RPCs have a footprint of about 23.5" (60 cm) x 15.75" (40 cm). This footprint utilizes the footprint of 48" x 40"
GMA pallet with a row of 3 RPCs lined up with the narrow RPC dimension of 15.75"
across the 48" dimension of the pallet on one edge and a row of 2 RPCs turned perpendicular to the first row with the longer 23.5" dimension across the 48"
dimension of the pallet. This is referred to as a 5-down footprint.
[000121 Conventional RPCs can be packed with 3 lines of fruit to achieve the 41.5 lbs. green fruit target due to the greater length of the container of 23.5"
vs. the length of corrugated boxes of 19.7, however the reduced number of containers per layer on the pallet of 5 vs. 6 dramatically reduces the quantity of bananas per pallet bad.
This issue has been somewhat mitigated by reducing the height of the RPC from 9.65" with the corrugated to about 9.22 in order for containers to be stacked 9 high on a pallet, by taking advantage of the reduced height of a 3 line pack, while introducing increased risk of high pack damage. However, this configuration still results in 6,25% less fruit per pallet load with only 45 (5 per layer, 9 high) containers per pallet bad in comparison to 48 (6 per layer 8 high) containers per pallet bad with corrugated. This loss in volume efficiency manifests itself as a gap in the center top of the RPC between the top 2 lines of fruit, since the RPC is just as wide as the corrugated box, but with one less line of fruit. Furthermore, conventional RPCs of these dimensions weigh about 4 bs., reducing the net payload of bananas even in traders with larger volurne capacity when compared with bananas in 3 lb. corrugated boxes.
[00013] Such efforts have not been successful in the North American market to date due to problems associated with using conventional RPCs with bananas, including:
Conventional RPCs hold fewer bananas per pallet load than corrugated boxes due to only five (5) containers per layer fitting on a pallet versus six (6) containers per layer, increasing freight cost, ^ Optimum ventilation across the about 40" dimension of the pallet cannot be achieved with conventional RPCs due to the perpendicular pattern of pallet loading.
= Optimization of RPC height to maximize pallet density results in "high packs" that can cause damage to the banana at the top of a container by the container above.
= Rigid RPC was can also cause damage to bananas relative to more flexible corrugated was.
= No reusable means for easy sampling of fruit without de-stacking the RPCs.
= Conventional RPCs cannot duplicate the net payload achieved with corrugated banana boxes even in larger over the road traders due to the greater tare weight of the container of 4 lbs. vs. 3 lbs, for corrugated.
SUMMARY
[00014] A novel design for a container has been developed that possesses advantageous properties and functionality. For example, the container can solve problems associated with conventional corrugated banana boxes, RPCs with the dimensions of conventional boxes and conventional RPCs with a 5-down footprint. The novel design can provide a more economical system for packing, cooling, shipping, ripening and merchandising bananas (and possibly other fruits, vegetables and produce items) that can improve food quality and reduce environmental impact.
[00015] Exemplary embodiments of the novel design can include one or more of these features:
[00016] New 6-Down Footprint ¨ An exemplary container can incorporate a reverse pallet loading pattern with three (3) containers across the approximately 40-inch dimension of the pallet and two (2) containers across the approximately 48-inch dimension. This pattern is achieved with dimensions of about 24" (60.96 cm) x13.33"
(33.87 cm). This is in contrast to the corrugated loading pattern with two (2) containers across the about 40-inch dimension and three (3) across the about 48-inch dimension.
This footprint factates packing of three (3) longer ones of fruit per container versus four (4) shorter ones in a corrugated box. Three (3) lines pile a maximum of 2 dusters or 4 banana fingers high with one line on the bottom of the RPC, one line on the top left and one line on the top right extending across the longer 24" dimension of the RPCs. This is in comparison with the 4 line corrugated pack where lines are piled up to 3 dusters high . .

that is the same height as the corrugated box of about 9.65". This lower pack height also facilitates the interlocking stacking of one open top RPC on top of the walls of another open top RPC not achieved with RPCs of the same dimension as corrugated boxes.
= =
[00017] The narrower about 13.33" (33.87 cm) dimension of the new RPC
optimizes the width of the RPC for a 3 line pack thus eliminating the open channel in the top center of a 3 line pack in a wider 15.75" (40 cm) 5-down RPC.
[00018] Further advantages of the new reverse 6-down footprint include exposure of all 3 lines of fruit in each RPC to forced air in ripening chambers in contrast to 4 line packs in corrugated boxes where the 2nd line of fruit is totally encapsulated in the other 3 lines.
- [00019] Increased Ventilation -The new pallet loading pattern, combined with the high-strength plastic construction also facilitates much greater ventilation across.
the top and/or bottom of each row of fruit or produce. The vent holes of the container are substantially greater than the size of the vent holes provided in conventional corrugated or RPC containers. The vent area for the container may be about two times greater, about three times greater, about four times greater or about five times greater than the ventilation provided in a conventional corrugated or RPC
container.
. This allows for increased ventilation. The greater ventilation can be about two times =
greater, about three times greater. about four times greater or about five times = greater than the ventilation provided in a conventional corrugated or RFC
container.
This is in sharp contrast to the pattern found in corrugated packs, where minimal Ventilation, is permissible and one of the four lines is almost completely insulated .
from ventilation. Greater ventilation translates into better cooling, temperature management, ripening control, 'quality and shelflife for the produce in the container.
This new pattern also solves the problems of conventional RPCs, permitting (1) = equal container load volume =

all airflow is forced in ripening chambers. The new pallet loading pattern allows the =
ventilation holes to line up consistently through all containers, there are reduced opening and channels for escape of forced air (often used in the ripening process), and =
this results in improved temperature management capabilities.
(00020] Greater Container Length and/or Width When Set Up Than When Folded Down -It is highly desirable to have the maximum .possible length and/or width of crates or boxes without those crates or boxes overhanging the pallets on which they rest. This allows the proper use of corner boards and straps to secure the crates in storage and transport. In the case of exemplary embodiments of the new crate design, this optimum length is about 24 inches (about 60.9 cm). However, the crates will be used in the North American retail. supply chain where they will often be mixed with conventional = RPCs that are only about 23.5 inches (60 cm) in length. Therefore, it is desirable for the new crates to be about 24 inches long when set up and filled with fruit or produce, but only about 23.5 inches long when folded down to facilitate mixing of empty folded =
crates on pallets. This is accomplished by a unique and novel design approach that not only accomplishes increased length and/or width when set up, but also does so without.
increasing the height of folded crates to optimize return freight. The full approximately 24-inch length in the set-up mode maximizes fruit (e.g., banana) or produce capacity and eliminates pallet underhang of crates that exist with other RPCs. This facilitates =
proper use of corner boards and prevents or substantially limits the flow of air between =
= . pallet loads in ripening rooms, to enhance ripening control.
(000211 Fruit Sampling -It is often desirable to randomly sample a fruit while it is in = boxes or crates that are often stacked eight (8) layers high in ripening rooms.

Corrugated boxes are cut open for sampling, using a knife. This procedure can damage fruit unnecessarily, and weakens the box, potentially contributing to further box failure and fruit damage, Conventional RPCs have no non-destructive means for fruit sampling when crates are stacked. The new crate has a unique and novel sample door to provide fruit graders access to fruit in every crate on a pallet without de-stacking. This access door can be opened and closed repeatedly throughout the life of the crate without affecting the structural integrity of the crate, the protection of the fruit (e.g,, bananas) or produce in the crate, or the life of the crate. The sample door may be contoured to match the contour of the wall in which the sample door is in, flexible to provide cushioning to the contents and to prevent damage, and tight-fitting so as not to create edges and gaps which could damage the contents [00022] Maximum Interior Volume ¨ Exemplary embodiments of the crate can incorporate several additional features to maximize the internal volume of the crate and minimize damage to bananas. The floor of crates can be substantially flat and smooth monolithic sheets of plastic. This can maximize internal height and minimize damage to fruit (e.g., bananas) or produce in a crate from the crate above, Conventional RPCs incorporate features which project from a crate down into the crate below for interlocking and stacking. Exemplary embodiments of our crate can interlock with features that project up from the top of crate walls only. Interior walls are also curved outward to the maximum dimensions to maximize internal volume, with all structure located on the perimeter of walls away from the curved fruit or produce. This construction also makes walls more flexible, smooth, curved and compliant where they are contacted by the fruit (e.g., bananas) or produce, further minimizing fruit or produce damage.
[00023] Lead-in for Stacking ¨ Conventional RPCs provide interlocking stacking, but no lead-in, so that crates have to be perfectly aligned in length and width for proper stacking. Without such perfect alignment, a conventional RPC crate corner may drop down into the crate below and damage fruit or produce. Exemplary embodiments of our crate's unique design include about 1/8 inch to about 1/2 inch of lead-in in both the length and width dimensions for easier stacking. Exemplary crates can also be slid in and out of place for easier stacking and de-stacking.
[00024] Latching of Sidewalis ¨ Conventional RPCs that are collapsible by folding are often designed to take on their set-up configuration by latching of their end wails. in contrast, exemplary embodiments of our crate's unique design employ latching of the sidewalls.
[00025] Thus, according to one aspect, an exernplaiy RPC provides a "collapsed"
configuration or an "erected" configuration comprised of a base, capable of being coupled or attached to a plurality of sidewails and a plurality of endvvails.
The RPC can further include two sidewails, each sidewall coupled or attached to the base so as to be movable between an upright position when the container is in an "erected"
position and a folded-down position when the container is in a "collapsed" position. The RPC can further include two endwalls, each endwall coupled to the base so as to be movable between an upright position when the container is an "erected" position and a folded-down position when the container is in a "collapsed" position. The RPC can further include an opening in each endwall for use as a handle for the container. The RPC can further include one or more latches on each endwall, each configured to couple an endwall to a sidewall when the container is in the "erected" configuration.
The RPC can further include one or more stops on each sidewall, each stop corresponding to a latch and configured to be in contact with that latch when the container is in the "erected"
configuration.
[00026] in an exempiary embodiment, the arrangement of plastic or resin shipping containers for shipping or storing bananas includes six shipping containers arranged on a top surface of a standard 48"-by-40" pallet, with three of the containers arranged across the 40" dimension of the pallet and two containers arranged across the 48"
dimension of the pallet. The arrangement provides three lines of bananas within each container compared to four shorter lines of bananas provided in a conventionai corrugated cardboard box. By providing three lines of bananas within each container, the bananas in the containers of the arrangement do not pile as high as the bananas in a conventional corrugated cardboard box, which results in less "high pack"
damage to the bananas in the containers of the arrangement when compared with bananas provided in the conventional corrugated cardboard box.
[00027] In an exemplary embodiment, the arrangement of plastic or resin shipping containers for shipping or storing bananas and providing enhanced ventilation to the bananas in the containers includes two or more containers arranged on a top surface of a standard 40"-by-48" pallet, In this arrangement, each container has two endwalls and two sidewalls and a plurality of vent holes in each of the sidewalls or endwalls. At least one container is arranged across the 40-inch dimension of the pallet and at least one other container is arranged across the 48-inch dimension of the pallet, so that the plurality of vent holes in the container sidewalls or endwalls completely or substantially align, providing enhanced ventilation to the bananas in the containers resulting from airflow passing through the pallet load in only one direction through the plurality of vent holes in the container sidewalls or endwalls.
[00028] )n an exemplary embodiment, a resin or plastic shipping container for shipping or storing produce includes two endwalls and two sidewalls that are moveably connected or attached to each other to allow the container to assume an "erected"
configuration, where the sidewalls and endwalls are all upright, and a "folded-down"

[00032] An exemplary embodiment is depicted in FIG. 1 as a collapsible container for the storage and transport of produce. The container 10 as fully erected includes a base 13 that extends in a horizontal plane, two endwalls 11 that extend in respective vertical planes, and two sidewails 12 that extend in respective vertical planes.
[000331 The container 10 is molded from a plastic or resin material, such as, for example, polypropylene, a resin or thermoplastic polymer or combination thereof.
Suitable materials can include resins, plastics or themioplasfics including, but not limited to, polyethylene, polypropylene, polyvinyl chloride, polyurethane, polyester, epoxy resin, phenolic resin, polystyrene, polycarbonate, combinations thereof and the like. The container 10 has a construction that is designed to be strong relative to its weight. The material of the container allows it to be rigid enough to maintain its structural form when erected for storage or transportation, thereby protecting the produce it contains. At the same time, the material of the base 13, endwalls 11, and sidewalls 12 of the container 10 are flexible enough to minimize damage to the contents of the container, [00034] The interior of the container 10 is primarily defined by the base 13, sidewalis 12 and endwalls 11. A handle 15 is located near the top center of each endwall 11. The base 13 is preferably a flat and smooth monolithic sheet of plastic.
This maximizes internal height and minimizes damage to produce on the top of the container due to contact from the container above. The shape of the endwalls 11, sidewalls 12, and base 13 are designed to reduce bruising conditions for the contents of the container. There are expansive, recessed areas (30, 31) in the endwalls and sidewalls. Much of the structure of the container, including hinges 45, stops 22, and latches 20 (each of which will be detailed below), is designed to be located on the perimeter of the was away from the curved contents of the container.
Preferably, the container has features for interlocking with other containers that project up from the top of container was. The endwalls 11 and sidewails 12 are preferably curved outward to maxirnize internal volume, and are constructed to be flexible, smooth, curved and compliant to minimize damage due to contact with the contents of the container.
[00035] Because the container is designed to hold produce that may be purposely ripened while in the container, the container has various ventilation holes 14 along its sidewails 12 and base 13, which allow for forced air to travel to the produce while packed in the container. FIG. 3 depicts the intended airflow pattern through a plurality of containers of an exemplary embodiment that are stacked in a multi-layer "six-down"
configuration. The placement of the ventilation holes 14 is designed to permit substantial alignment of the ventilation holes 14 of several containers when stacked on a pallet, which is a typical arrangement of the containers when filled with produce that are subject to ripening by forced air in a ripening room or ripening chamber.
This alignment creates a pathway for the forced aft to easily reach produce that is stacked in the containers throughout the pallet, [00036] The endwalls 11 and sidewalls 12 of the container can be connected to the base 13 through the use of a plurality of hinges 45 or other movable couplings. HG.
7 depicts the hinges 45 on the sidewall, The hinges 45 will permit the endwalls 11 and sidewalls 12 to be folded down toward the base 13 when the container is in the "coliapsed" configuration, and the hinges 45 will allow the endwalis 11 and sidewalls 12 to be moved to an upright position when the container is in the "erected"
configuration.
In changing the container from the "erected" configuration to the "collapsed"
configuration, the first sidewall 12 will be folded down over the base 13, then the second sidewail 12 will be folded down toward the base 13 and will overlap part of the first sidewall 12. Next, the two endwalls 11 will be folded down toward the base 13 and over the sidewalls 12, This "collapsed" configurafion results in the container being made much more compact than when in the "erected configuration." The relatively flat, compact container in the "collapsed" configuration can be easily transported for reuse.
When in the "collapsed" configuration, many of the containers can be stacked for easy transport and/or storage.
[00037] From the "collapsed" or "folded down" configuration, the container can be changed into the "erected" configuration by first unfolding the endwaHs 11 and raising each of them to an upright position. Then, one sidewall 12 is raised and is coupled to the two endwalls 11. Finally, the second sidewali 12 is raised and is coupled to the two endwalls 11.
[00038] Several features of an exemplary embodiment of the container can aid in assembly, specifically the transition of the container from a "collapsed"
configuration to an "erected" configuration. Some of these are shown in FIG. 4 and HG. 5. An exemplary embodiment uses a latch 20 and stop 22 to couple the sidewall 12 to the endwall 11. When the inside edge 23 of the sidewall passes the latch 20, the latch 20 springs back into position and hits a stop 22 on the sidewall 12. This contact between the latch 20 and stop 22 can result in a clicking sound that helps the user know that the latch 20 has engaged the stop 22 and that the endwali 11 and sidewall 12 are thereby coupled. The latch 20 can be flexed or otherwise actuated to enable it to first become displaced while the edge of the sidewall 12 contacts it and passes by it, but then spring back to engage the stop 22 on the sidewall 12.
[00039] In an exemplary embodiment, the edges of each endwall 11 and sidewall 12 include a series of vertically-spaced "I.." or "L-shaped hooks 50 that allow an endwail 11 to interlock with a sidewall 12 when both are upright and overlap when the container is in the "erected" position. This further promotes dose coupling of the endwails 11 to the sidewalls 12, promoting the structural integrity of the container 10 in the "erected"
configuration and thereby reducing damage to the contents of the container.
[00040] While many conventional RPCs are collapsible by folding, they are often designed to take on their set-up configuration by latching of their end was.
Such endwall latching can result in inadvertent disengagement of the /atches (and resulting col/apse of the RPC) during carrying and stacking due to the exertion of lateral forces against the handles or end was. This can result in damage to the contents of the container. As indicated above, an exemplary embodiment of the container has a unique design that employs latching of the sidewalls 12, which reduces inadvertent disengagement, since lateral force against the handles and end was during carrying and stacking will not disengage the latches. In addition, the use of "L" hooks 50 to couple each sidewaH 12 to each endwall 11 will further counteract any lateral forces on the handles and endwalls. FIG. 8 depicts a cross section of a sidewall 12 and endwall 11 when coupled through the use of "L" hooks 50.
[00041] In an exemplary embodiment, one or more of the sidewalls 12 or endwalls 11 will have an opening within which a door 40 is mounted in such a way that does not cut through the perimeter of the sidewall 12 or endwall 11. Such door 40, which can be constructed from the same material as the sidewall 12 or endwall 11, can be hingeably mounted or attached to the opening to allow the door 40 to pivot and be opened and closed. Opening the door 40 permits visual inspection and/or sampling of the product in the container 10, even when the container is within a stack of other containers on a pallet. The door 40 can be closed again, renewing the protective barrier that the endwall 11 or sidewall 12 provides to the contents of the container 10 in storage or transport. Preferably, when the door 40 is in the closed position, the door 40 is coupled or attached to the sidewall 12 or endwall 11 by a clip 41 that prevents the door 40 from opening without user action.
[00042] FIG. 7 and FIG. 7a depict an exemplary embodiment with the opening and door 40 in the sidewall, and the clip 41 having the form of a spring tang.
This embodiment of the curved fruit sampling door 40 incorporates a clip 41 that, when engaged, holds the door 40 closed and when disengaged allows the door 40 to open to provide access to the contents of the container 10. Preferably, the clip 41 is a "low profile spring tang" mechanism which fits within the thickness of the sidewall 12 or endwall 11, not extending inside the curved surface of the sidewall 12 or endwall 11 or outside the plane as defined by the outside surface of the sidewall 12 or endwall 11.
The mechanism of the clip 41 is reusable, allowing for repeated opening and closing of the sample door 40. The clip 41 is rotated outward to disengage the clip 41 and allow the door 40 to open. The door 40 and clip 41 are rotated inward with slight pressure to engage the clip 41 and the latch bracket 42. Because of the door's 40 material, its hinged connection 47 and the use of the clip 41 to secure it, the door 40 can be opened and dosed repeatedly throughout the life of the container 10 without affecting the structural integrity of the container, the protection of the product in the container, or the life of the container.
[00043] In a preferred embodiment, the dimensions of the container 10 are optirnized for use in a particular product market or supply chain. It is desirable to have the maximum possible length of a container 10 without overhanging the pallets on which a container or multiple containers are placed. In the case of an exemplary embodiment of the container for use with bananas, where 40-inch by 48-inch pallets are customarily used, the optimum exterior length for a container 10 is about 24 inches (about 60.9 cm) and the optimum exterior width is about 13.33 inches (about 33.9 cm). With these dimensions, the container 10 could be placed on pallets in a six-down configuration, a pallet loading pattern with three (3) containers across the approximately 40-inch dimension of the pallet and two (2) containers across the approximately 48-inch dimension. See FIG. 2 and FIG. 3 for illustrations of a "six-down"
configuration.
[00044] In the North American retail supply chain, containers are likely to be mixed with conventional RPCs that are only about 23.5 inches (about 60 cm) in exterior length.
Accordingly, it is desirable for the container 10 to be about 24 inches long when erected and filled with bananas, but only about 23.5 inches long when folded down to factate mixing of empty folded crates on pallets. The novel design approach accomplishes the increased length when erected, but does so without increasing the height of foided containers 10 to optimize the number of containers 10 that can be packed on pallets for return. FIG. 10a depicts the profile of one end of the container when in the "collapsed"
configuration. Fig, 10b depicts the profile of the same end of the container when in the "erected" configuration, showing the additional length of the container in the "erected"
configuration when compared to the length of the container in the "collapsed"
configuration, The approximately 24-inch iength when erected maximizes banana capacity and eliminates pallet underhang that exists with other RPCs. These dimensions also dose gaps between pallets for better transport stability and airflow.
This brings the added benefit that corner boards can be properly used to prevent the flow of air between pallet loads in ripening rooms, so that ripening can be more precisely controlled.
[00045] In a preferred embodiment, a container 10 with an exterior measuring approximately 24 inches long by approximately 13.33 inches wide results in interior dimensions that facilitate packing of three (3) longer lines of curved fruit (e.g., bananas) per container. Three (3) lines don't pile as tall as the four-line arrangement commonly used in conventional banana containers, and this lower packing height results in less "high pack" damage to the banana in the container. Fla 9a depicts the first line of packing of bananas. FIG. 9b depicts the second line of bananas packed over the first line, partially overlapping it. Finally, FIG. 9c depicts the third line of bananas packed, which also partially overlaps the first line. A preferred embodiment also includes added height to the container 10 to prevent "high pack" damage, with the preferred exterior height for a container for bananas being approximately 9,66 inches.
[00046] I n a preferred embodiment, the container 10 includes some extra material 60 in its dimensions to promote easier stacking without the need for perfect alignment.
in an exemplary embodiment, this lead-in material 60 includes about 1/8 inch to 1/2 inch lead-in in both the length and width dimensions for easier stacking. Exemplary containers can also be slid in and out of place for easier stacking and de-stacking as a result of this lead-in material.
[00047] In another embodiment, the endwalls 12 and sidewalls 11 are optimized for the storage of transportation of pineapples, specifically through the use of wall shaping and recessed areas designed to protect the barrels and crowns of pineapples, and the abty to adjust the height of the container 10 at the time of packing to closely fit the pineapples in the container.
[00048] While the application has been described in terms of various specific and preferred embodiments, the skilled artisan will appreciate that various modifications, substitutions, omissions, and changes may be made without departing from the spirit thereof. Accordingly, it is intended that the scope of the present application be limited soiely by the scope of the following claims, including equivalents thereof.
