Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 61/601,649, filed Feb. 22, 2012.

TECHNICAL FIELD

The present invention relates to crates and systems for transporting living plant material, and methods of making and using crates and systems for transporting living plant material.

BACKGROUND

Plant agriculture can generally be divided into three broad categories: (a) agronomy (i.e., herbaceous field crops grown on a large scale in cultivated fields); (b) forestry (i.e., forest trees and related products); and (c) horticulture (i.e., edible garden crops and plants for ornamental use). As with many other industries throughout the world, plant agriculture has evolved into a high specialized, commercial enterprise advanced by science and technology so as to efficiently and cost effectively deliver products in pace with the ever increasing demand of these products.
Arguably, in the past few decades, the fastest growing segment of plant agriculture as a whole is in the area of ornamental plants. Increased desire in using plants for interior decorating, emphasis on home and garden decoration and designing neighborhood and community land with aesthetically pleasing plants have all contributed to the demand for ornamental plants. This increased demand has generated a multi-billion dollar industry integrally supported by horticulturalists, botanists, geneticists, nurserymen, landscape architects, arborists, garden center operators, pest control specialists, and professional landscape services to name a few.
The increased demand for ornamental plants has fueled innovation in the horticultural industry for the mass propagation of elite, high yielding and disease free plants. Among such advancements is the method of young plant production. Mass production of young plants generally involves professional breeders and propagating companies that develop plant starting material, which it then ships or delivers to professional growers. The plant starting material is typically in the form of cuttings (rooted or unrooted), seedlings, or tissue-cultured propagules. Once delivered to the growers and/or plant raisers, the plant starting material is placed into propagation trays or liners where they are grown side by side in small cells in a propagation media that has been specifically developed to reduce weeds or diseases and provide a suitable environment to accommodate the plant at this fragile state of its life.
The trays or liners are then placed within a controlled environment, such as a greenhouse where the young plant begins to grow. State of the art greenhouses are equipped with computer-controlled system capable of monitoring the progress and quality of thousands of plant trays. Once the plant trays are ready to leave the green houses, they are transported to a professional grower who then removes the plant from its initial cell in the tray and into a larger container or field with the appropriate growing medium to sustain the growing plant.
When the young plant is ready to leave the greenhouse, it is still quite fragile and its transportation to the wholesalers who then distribute the product to the retailers. Alternatively, some retailers will import the young plants directly from the growers. Regardless of the selected links in this chain, it may be easily appreciated that some degree of care must be exercised in transporting these plants at such a vulnerable stage of their life while balancing the need to cost effectively transport these plants in mass quantities.
A common practice of transporting the trays is for the trays to leave the grower in movable carriers, or so-called “Danish trolleys”. The trolleys are then rolled from place to place until the young plants reach their destination. On these trolleys, the trays are set upon an exposed shelving unit that generally lends itself to the displacement of the trays and subjects the young plants to damage or even loss. Further, the load capacity of these trolleys is very inefficient. Another common practice is to place the trays inside corrugated packaging solutions. However, the young plants need to be well ventilated and the boxes disrupt the view of the young plants for quality checks. Further, cardboard boxes generate waste and thus are not cost effective and take up humidity/water resulting in softer material and thus unstable for stacking one on top of another.
With reference to FIG. 1 through FIG. 3, three types of propagation trays 10, 20, and 30 are shown. These propagation trays 10, 20, and 30 are known in the art. Each tray contains cells 11, 21, and 31, which are adapted to receive plant starting material (not shown). Once disposed therein, the plant starting material is provided with a suitable environment to permit growth of the material into young plants 22, 32, shown for example in FIGS. 2 and 4. In commercial operations, the filled trays are placed in greenhouses where the plants can be grown in a controlled environment.
Once the young plants are mature enough, they are ready to be transplanted either in a field or another suitable container with the proper growth media to support the next stage of the plant's life. In commercial operations, for example, the filled propagation trays 36 are collected and loaded onto wheeled trolleys 40 such as the one shown in FIG. 5. The trolleys are then transported to professional growers.
As shown in FIG. 5, exemplary trolley 40 contains a vertical array of shelves 42 and filled trays 36 simply disposed thereon. Shelves 42 do not contain any sidewalls to offer protection for plants 32 during such a vulnerable stage in its life cycle.
While these common practices are currently acceptable, there is an increasing need felt for many years to develop a carrier and a carrier system that avoids these drawbacks, not only from a cost perspective, but simply to avoid loss of product to meet the ever increasing demands. Accordingly, there is a need for solutions to reduce or eliminate loss or injury of young plants and provide added security measures to protect the young plants while they are transported to their destination. There is also a need to provide a carrier and carrier system that enables the young plants to remain visible during transportation and delivery for quality control purposes. At the same time, it is also desirable to meet these needs without frustrating the carrier's ability to deliver mass quantities of young plants in a manner that is both time efficient and economically feasible.

DETAILED DESCRIPTION

According to the present invention, a stackable crate is provided that is adapted to receive selected items for transportation from a sender location to a recipient location. The crate is particularly useful for receiving at least one propagation tray of young plant material and is stackable such that multiple filled crates can be palletized to transport large quantities of the young plants in a protected environment.
With reference now to FIG. 6, the present invention is directed at providing crates to house the propagation trays in an environment constructed to reduce risk of injury to the young plant during shipment. As shown, crate 150 is generally in the shape of a rectangular frame 152 having first and second sidewalls 151 and 151′ and first and second end walls 153 and 153′. Frame 152 generally extends between an upper frame portion 154 and a lower frame portion 156 thereby to define an interior volume 158 for receiving the young plants therein. More particularly, crate 150 may be used to receive plant propagation tray 10, such as that shown and described with respect to FIG. 1, thereby to define a filled crate once the young plant material is disposed therein. As should be appreciated, crate 150 may be used to receive other known propagation trays, such as tray 20 shown in FIG. 2, or may simply receive a selected number of potted plants.
Crate 150 having the features describe above may be constructed as a unitary one-piece construction. Frame 152 may further be provided with any desired pattern of apertures 174, preferably sufficient to permit the ventilation of the young plants therein during shipment and proper visibility of the same with sufficient dimensions suitable for protecting the young plants. Further, crates 150 may be formed of any suitable material that will safely transport the young live plants during the normal rigors of transportation. Such material includes, but is in no way limited to polypropylene, wood, and corrugated material.
With continued reference to FIG. 6, frame 152 has a generally open top area 160 and open bottom area 164 each surrounded by a respective top and bottom edge 162 and 166. To accommodate support of the propagation tray therein, crate 150 may further be provided with flange 170, located proximate to lower frame portion 156 and extending laterally inwardly to receive and support tray 10 thereon. For additional support of the tray, cross-beam 172 may be provided to extend across the open bottom area between selected walls of the frame. As shown here as an example, cross-beam 172 is centrally located and extends across the open bottom area 164 between sidewalls 151 and 151′ of frame 152.
In addition, frame 152 may be provided with at least one passageway 176 formed therethrough and in communication with the interior. As shown in FIG. 7, passageway 176 may assist with the placement of the tray into or removal from the interior of the crate. As shown here, passageway 176 is configured to permit ingress and egress by a person's hand, but the passageway is not limited to this configuration. For example, the passageway could be configured as an elongate channel or slot sized to permit ingress or egress of at least one finger.
With continued reference to FIG. 6 and additional reference to FIGS. 8 and 9, crate 150 is constructed to be stackable, one on top of another, with either a crate of similar construction 150 or with propagation tray 30, shown in FIG. 3, as a stacked ensemble. To accommodate this feature, crate 150 is provided with first and second connectors 180 and 182 that are matable with a second crate of similar construction. First connectors 180 are generally shown here as a pair of recesses 184 formed in frame 152 at a location proximate to upper frame portion 154. Recesses 184 are adapted to receive and mate with second connector element 182, which extends downwardly from frame 152 at a location proximate to lower frame portion 156 to terminate in a pair of connecting feet 186. Preferably, first and second connector elements 180 and 182 are located at each of the four corners of rectangular crate 150.
Similarly, and with reference to FIG. 3, propagation tray 30 is provided with a plurality of first connectors 80 located proximate to a top portion 54 thereof and second connectors 82 located proximate to a bottom portion 86 thereof. Second connectors extend downwardly to terminate into a pair of connecting feet 86 that are adapted to be received and mated with one pair of recesses 84 of a similarly constructed tray. Of course, as should be appreciated, the construction of first and second connectors need not be limited to configuration of recess and feet, but have been done in this manner primarily to accommodate tray 30, which is known and in current use in commercial operations for the transportation of young plants. Accordingly, crates may be configured with alternate matable connectors to permit stacking of the crates in a suitable manner.
As shown in FIG. 8, upper crate 150 is stacked on top of and supported by lower crate 250 and lower crate 250 is stacked on top of tray 30 such that tray 30 supports both crates 150 and 250 as an ensemble of stackable crates. Further, feet 186 of upper crate 150 are received by recesses 284 of lower crate 250. Similarly feet 286 of crate 250 are received by recesses 84 of propagation tray 30. Recesses 184 of the upper crate 150 remain available to receive the feet of an additional crate or propagation tray if desired. As may be appreciated, the young plants that would be nested within the cells of the propagation trays would be surrounded and protected by the respective sidewalls of crates 150 and 250.
FIGS. 9 and 10 show alternate ensembles of stacked crates and trays. FIG. 9 shows stacked crates 150, 250 and 350, each with a propagation tray 10 disposed therein. As should be appreciated from the description above, top crate 150 is ready and able to receive another crate or propagation tray 30 thereabove. Similarly, all crates 150, 250 and 350 could be supported below by an additional crate or propagation tray 30. FIG. 10 shows a stacked ensemble of crates 150, 250 and 350, and 450 with trays 30 and 130. As desired, a selected ensemble of crates or crates and trays, may be palletized to ship mass quantities of young plants to a desired location.
Alternate constructions of the crates are also contemplated by the present invention, examples of which are shown in FIGS. 11 and 12. As shown, crates 550 and 650 are similar in design and stackable by means of matable connectors as described in some detail in reference to FIGS. 6, 8, and 9. Here, crates 550 and 650 include alternative frame constructions 552 and 652 for ventilation and visibility of the young plants to be disposed in the respective interior thereof and for alternative aesthetic appearance.
Finally, a method of transporting young plant material to an intended recipient is provided by the present invention. The method includes providing a desired number of crates that contain therein a plant propagation tray of young living plants wherein the crates include matable connectors whereby an upper filled crate is mated to and supported by a lower filled crate to define a stacked ensemble. Further, suitable propagation trays that include matable connectors can also be used to support or be supported by these filled crates to define a stacked ensemble. A suitable number of stacked ensembles may then be palletized for transportation of the young plants to a desired location.

EXAMPLES

Example 1

Manufacture of Stackable Crates

Stackable crates, similar to stackable crates 150 shown in FIGS. 1-20, were prepared. The stackable crates were used in combination to form ensembles containing two or more stackable crates. The stackable crates of the ensembles were filled with living plants and palletized on one or more pallets to transport the living plants from a first location to a second location. The stackable crates/ensembles protected the living plants during transportation.
It should be understood that although the above-described stackable crates, ensembles of stackable crates, and methods are described as “comprising” one or more components or steps, the above-described stackable crates, ensembles of stackable crates, and methods may “comprise,” “consists of” or “consist essentially of” any of the above-described components, features or steps of the stackable crates, ensembles of stackable crates, and methods. Consequently, where the present invention, or a portion thereof, has been described with an open-ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description of the present invention, or the portion thereof, should also be interpreted to describe the present invention, or a portion thereof, using the terms “consisting essentially of” or “consisting of” or variations thereof as discussed below.
As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” “contains”, “containing,” “characterized by” or any other variation thereof, are intended to encompass a non-exclusive inclusion, subject to any limitation explicitly indicated otherwise, of the recited components. For example, a crate, an ensemble, and/or method that “comprises” a list of elements (e.g., components, features or steps) is not necessarily limited to only those elements (or components or steps), but may include other elements (or components or steps) not expressly listed or inherent to the crate, ensemble, and/or method.
As used herein, the transitional phrases “consists of” and “consisting of” exclude any element, step, or component not specified. For example, “consists of” or “consisting of” used in a claim would limit the claim to the components, materials or steps specifically recited in the claim except for impurities ordinarily associated therewith (i.e., impurities within a given component). When the phrase “consists of” or “consisting of” appears in a clause of the body of a claim, rather than immediately following the preamble, the phrase “consists of” or “consisting of” limits only the elements (or components or steps) set forth in that clause; other elements (or components) are not excluded from the claim as a whole.
As used herein, the transitional phrases “consists essentially of” and “consisting essentially of” are used to define a crate, an ensemble, and/or method that includes materials, steps, features, components, or elements, in addition to those literally disclosed, provided that these additional materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed invention. The term “consisting essentially of” occupies a middle ground between “comprising” and “consisting of”.
Further, it should be understood that the herein-described stackable crates, ensembles of stackable crates, and methods may comprise, consist essentially of, or consist of any of the herein-described components and features, as shown in the figures with or without any feature(s) not shown in the figures. In other words, in some embodiments, the stackable crates, ensembles of stackable crates, and/or methods of the present invention do not have any additional features other than those shown in the figures, and such additional features, not shown in the figures, are specifically excluded from the stackable crates, ensembles of stackable crates, and/or methods. In other embodiments, the stackable crates, ensembles of stackable crates, and/or methods of the present invention do have one or more additional features that are not shown in the figures.
While the specification has been described in detail with respect to specific embodiments thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing, may readily conceive of alterations to, variations of, and equivalents to these embodiments. Accordingly, the scope of the present invention should be assessed as that of the appended claims and any equivalents thereto.
