(1) Field of Invention
The present invention relates to food shipments and, more particularly, to a shipping container (the “Vessel”) that enables the transport via common carrier of fresh foods within a re-usable, temperature-controlled and impact-protected shipping Vessel.
(2) Description of Related Art
Shipping containers have long been known in the art. Shipping containers come in a variety of forms and are used to ship a variety of products. By way of example, a traditional shipping container is a cardboard box that can be used to ship any number of items. While operable for holding items therein, such a shipping container may not be desirable to ship cold-food products since it does not maintain temperatures well nor is it designed to maintain a consistent temperature (within a narrow temperature range) throughout the container.
As an enhancement over traditional cardboard boxes, some retailers ship cold food products in Styrofoam™ (“Foam”) containers. While such Foam containers are functional for maintaining food products at a cooled temperature, they are not durable, present environmental problems once they are out of service and lack a lot of the functionality that is provided by the present invention. For example, Foam containers are not capable of maintaining a consistent temperature throughout the container within a narrow temperature range. As another example, a traditional Foam container is typically filled by simply stacking items therein. By stacking items on top of and next to one another, a traditional Foam container does not provide for convective and/or conductive properties that can be employed to maintain a consistent temperature throughout the container for prolonged periods of time. Further, a traditional Foam container allows a user to simply place several items therein, but does little to catalog actual placement of those items (which may be desirable if the food is being sent to multiple consumers at one shipping location).
Thus, a continuing need exists for a new and improved fresh food shipping container that solves the aforementioned problems and, in doing so, provides for (1) convective and/or conductive properties to maintain a consistent temperature throughout the container (within a narrow temperature range) for prolonged periods of time; (2) allows for specific inventory control; (3) ease of shipping by common carriers; (4) reduces waste and provides for re-usability; and (5) provide for remote monitoring and analysis of the status of the container and its contents.
The present invention relates to food shipments and, more particularly, to a fresh food shipping Vessel for safely and effectively shipping fresh foods. The shipping Vessel includes an insulation cage that adapted/formed to hold one or more drawers therein. Further, the Vessel includes one or more drawers for positioning within the insulation cage, each drawer adapted to hold at least one item thereon.
In one aspect, the insulation cage includes a crate and a tub, with an insulation layer entirely sealed between the crate and tub.
In yet another aspect, the insulation cage includes a lid for sealing the one or more drawers within the insulation cage.
In another aspect, the insulation cage includes a plurality of insulation cage magnets and wherein the lid includes a plurality of lid magnets, with the insulation cage magnets and lid magnets being polarity keyed such that the lid is attachable with the insulation cage in a single configuration.
Further, the one or more drawers each include side walls surrounding a thermally conductive bottom portion, whereby the thermally conductive bottom portion is operable for providing conduction and radiation to items amongst the drawers.
In yet another aspect, the drawers include slots formed through the side walls, whereby the slots are operable to provide for convection flow amongst the drawers.
In another aspect, the thermally conductive bottom portion includes a plurality of holes formed there through, whereby the holes are operable to provide for convection flow amongst the drawers.
Further, a plurality of containers are included for attaching with a drawer, each of the containers having a plurality of protrusions.
Additionally, each drawer includes container connectors formed in the thermally conductive bottom portion, the container connectors being formed as recesses to receive the plurality of protrusions and hold the container in place during transit. The container connectors and holes are positioned in the bottom portion such that when the containers are affixed with the container connectors, the holes are positioned between side walls of adjacent containers and remain uncovered by the containers, thereby assisting convection flow amongst the drawers.
In another aspect, at least one temperature plate is included for positioning within the insulation cage, the temperature plate adapted to maintain a desired temperature for a period of time. The temperature plate is a cold plate that includes a void having water therein, whereby a shipper can freeze the cold plate to provide a cold temperature to the vessel during transit.
Further and in another aspect, the Vessel includes an outer protective shell for holding the insulation cage therein. The shell includes front loading doors with a single, center closing seam.
In another aspect, a ratcheting latch mechanism can be included that spans the center closing seam and is adapted to pull the seam tightly closed to seal the doors in a closed position. The ratcheting latch mechanism includes a first part for connecting with a first door and a second part for connecting with a second door, the first and second parts being detachably attachable with the first and second doors, respectively, whereby each of the first and second parts are replaceable in the event of damage. The first part includes an elongated portion with a clasp portion attached with the elongated portion via a hinge, the clasp portion having a clasp and a lifting handle. The second part includes a catch formed to receive and lockingly engage with the clasp.
In another aspect, a tamper proof latch system is included, whereby the tamper proof latch system is operable for providing assurance to an end user that contents of the vessel have not been tampered with during transit. The tamper proof latch system includes a band and slots formed through the second part, the slots formed to accommodate the band and position the band over the clasp portion such that lifting the clasp portion causes the band to break.
In another aspect, the shell includes an interior, an exterior, and outer walls, and further comprising one or more handle assemblies that are detachably attachable with the outer walls. Each handle assembly includes a base plate and a faceplate, the baseplate having a spring-loaded handle pivotally attached thereto, with the base plate positioned in the interior of the shell and secured to the faceplate that is positioned on the exterior of the shell, thereby providing a replaceable, secure and retractable handle.
In another aspect, open connectors are affixed with the doors and outer walls of the shell, the open connectors being positioned such that when the doors are swung entirely open, the open connectors engage with one another to maintain the doors affixed against the side walls in an open position. In one aspect, the open connectors are magnets.
In another aspect, the shell is formed of a corrugate plastic and the shell and insulation cage are substantially cube-shaped.
Finally, the present invention also includes a method for forming and using the invention described herein. The method for forming the Vessel comprises a plurality of acts of forming and assembling the parts described herein to collectively form the Vessel. The method for using the Vessel comprises a plurality of acts of loading and shipping the Vessel with the relevant items and containers.

(1) Description
As noted above and as illustrated in
The shipping Vessel 100 includes several components, including an outer protective shell 102, an internal insulation cage 104, a plurality of drawers 106, and a closing lid 108. As will be evident below, each of the components of the shipping Vessel 100 provide several unique features that individually and collectively further enhance the operability of the shipping Vessel 100.
As noted above, the shipping Vessel 100 includes an insulation cage 104. The insulation cage 104 is any suitable insulating container or box that is operable for maintaining cold (or hot) items therein. As a non-limiting example and as shown in
As can be appreciated by those skilled in the art, by sealing (e.g., via a watertight plastic weld seal) the insulation layer 202 between the crate 200 and tub 204, the insulation cage 104 provides substantial insulating properties, yet can also be easily cleaned and sanitized without detrimentally affecting the foam (i.e., insulation layer 202) therein. In other words and in one non-limiting aspect, the crate 200 and tub 204 completely cover the insulation layer 202 so that the crate 200 can be sterilized while not contaminating the insulation layer 202. The tub 204 piece, in one non-limiting example, is a thin plastic film that prevents external contamination of the foam insulation. In another aspect, material selection for the Vessel and its insulation cage 104 involves the use of plastics and smooth surfaces so that chances of bacteria build up are reduced and the ease of sterilization is maintained.
For further understanding,
Further and as illustrated in
In one aspect, the plurality of compartments (e.g., drawers 106) can be used to allow for shipment of several different items to a variety of individuals. Imagine a scenario where a plurality of consumers each order a different lunch meal (e.g., a sandwich, crackers, salad, etc.). Each consumer would ideally prefer to know exactly which drawer 106 contained their particular food item. In order to allow for such functionality it is desirable to catalog which drawer 106 contains which item. In one aspect, a label (e.g., sticky label) can be adhered to the end of the drawer identifying the contents of a particular drawer or an end consumer's name. Alternatively and as depicted in
In addition to allowing for unique identification capabilities, the drawers 106 can be designed to assist in maintaining a consistent temperature throughout the Vessel. As a non-limiting example, the drawers 106 are designed to provide for both convection and conduction. Due to the convective and conductive properties of the Vessel (and/or drawers 106), fans are not required to maintain optimal temperature throughout the Vessel. For example and as shown in
In another aspect, the edges of the drawings 106 can optionally be formed to include ridges 502 near convection slots 504 that would prevent a food pack from sliding over and covering a convection slot 504, thereby further assisting in air flow within the Vessel.
In another aspect, the drawers 106 are formed entirely of any suitably stable material, a non-limiting example of which includes plastic. However and as noted above, the drawers 106 can also be designed to provide for conduction. Thus, the drawers 106 are optionally formed, at least partially, of any suitable material that enhances thermal conduction, a non-limiting example of which includes metal. For example and in one aspect, metal conduction plates can be included between the drawers 106, with metal disks formed in the drawers 106 to further enhance conduction between the metal plates and the layers of drawers 106. Alternatively, the drawers 106 are desirably formed such that a bottom portion 508 (i.e., the portion that includes the holes 500) of the drawers 106 is formed of a thermally conductive material (e.g., metal). In this aspect, the side walls 510 can be formed of plastic, with the metal bottom portion 508 affixed with (e.g., via a tongue and groove connection, etc.) and surrounded by the plastic side walls 510. Thus, temperature can be easily transferred between drawer 106 levels via the metal bottom portion 508, while the plastic side walls 510 provide stability yet decrease overall weight of the drawer 106 (as opposed to metal side walls). Referring again to
Thus, in operation, the packer would position a pre-frozen (or pre-heated) temperature plate 310 into the crate 200 when packing the Vessel to provide a temperature (cold or hot) source therein. The temperature plate 310 can be affixed with the insulation cage 104 in any desired manner. As a non-limiting example and as illustrated in
In addition to their thermal conductive/convective properties, the drawers 106 can also be shaped to provide optimal space utility. It should be understood that the drawers 106 can be formed in any desired shape; however, in a desired aspect, the drawers 106 can be formed in a square shape that allows for optimized space utilization and cube formation when stacked.
Further, it should be understood that any item or container can be packed in the drawers 106. As a non-limiting example, the invention includes individual food containers that are specifically designed to minimize lateral space waste and increase the conductive and convective properties of the Vessel. Several non-limiting examples of such containers are illustrated in
For example,
Further, the protrusions 529 can be formed of any desired depth or length. For example, the protrusions 529 can be formed to protrude through the bottom container connector 501, yet be flush with the bottom-side of the drawer 106 (in which the particular container is attached). This aspect would allow for air flow in the drawer 106 compartment below to engage with the protrusion 529 and, in doing so, provide a cooling effect to the contents of that particular container. In another aspect, the protrusions 529 are of a sufficient depth or length such that they protrude through the thickness of the bottom of the drawer 106 and contact a container or ice pack in the drawer 106 compartment below. For example, if an ice pack were positioned directly below a particular drawer 106 and container 520, the protrusion 529, via contact with the ice pack [cold source?], would assist the conductive properties of the Vessel by allowing the temperature of the ice pack to more easily transfer to the contents of the particular container 520. As can be appreciated by those skilled in the art, the protrusions 529 and container connectors 501 as described and illustrated are provided as but one non-limiting example according to the principles of the present invention and it should be understood that such connectors 501 and protrusions 529 can be reversed and/or positioned at any desirable location on the respective container 520 and drawer 106.
For further understanding.
For further understanding,
It should also be noted that the containers can be formed such that the side walls 552 rise from the ground surface at any desired angle. As a non-limiting example and as illustrated in the figures, the side walls 522 can be formed at an angle such that they do not lay flat against an adjacent container. In other words, the side walls 522 are formed at angles to provide gaps 524 between adjacent containers. An advantage to this aspect is further illustrated in
As noted above and as illustrated in the cross-sectional side-view illustration of
As noted above and as further illustrated in
The concept of radiation 594 and convection 590 is further illustrated in the front-view illustration of
Referring again to
A clip 610 is optionally included and affixed with the inner lid portion 604 using any suitable mechanism or device, a non-limiting example of which includes the pressure sensitive tape 608. The clip 610 is operable to hold paper, receipts, inventory, return shipping instructions, or any other suitable communication that is desirable to provide to the recipient of the shipping Vessel. Further, the inner lid portion 604 can be formed with a recess 620 that accommodates such a communication. As a non-limiting example, the recess 620 can be formed to fit an A4 of 8½ by 11 paper.
As noted above, the door gasket 612 is attached (e.g., via an adhesive or PSA) with the inner lid component 604. The door gasket 612 is any suitable mechanism, material, or device that is operable for providing an air seal between the lid 108 and the insulation cage when the lid 108 is affixed with the insulation cage. A non-limiting example of such a suitable door gasket 612 is foam and/or rubber weather stripping. Further, to assist the lid 108 in maintaining connectivity with the insulation cage, the shipping Vessel includes a cage locking device. The cage locking device is any suitable mechanism or device that is operable for locking the lid 108 in place against the insulation cage, non-limiting examples of which include clasps, latches, keyed locks, etc. In a desired aspect, the cage locking device includes the plurality of lid magnets 614 that are polarity keyed to insulation cage magnets such that the lid 108 can only be attached one way. For example and referring again to
As noted above, the plurality of lid magnets 614 are polarity keyed to insulation cage magnets 312 such that the lid 108 can only be attached one way. As a non-limiting example, all of the lid magnets 614 (except one) can be attached such that the positive sides of the magnets 614 protrude from the lid 108. One lid magnet 614 is reversed such that its negative side protrudes from the lid 108. In this aspect, the insulation cage magnets 312 would all be positioned (except one) such that their negative sides are directed to toward the lid 108. One insulation cage magnet 312 is reversed such that its positive side is positioned toward the lid 108. Thus, as can be appreciated by those skilled in the art, there would only be one configuration in this example in which the lid 108 would adhere to the insulation cage 104.
As illustrated, the lid 108 is freely removable from the insulation cage 104. However, in another aspect, the lid 108 can be designed such that it is connected with the insulation cage 104 via a hinge.
In another aspect and as illustrated in
As noted above and illustrated in
Because the shell 102 is reusable, it may be subject to wear. As such, some or all parts of the outer protective shell 102 can be easily replaced should a part turn out to be broken or no longer functional. The design is implemented so that the failure of one part on the shell 102 will desirably not jeopardize the usability of the shell 102 as a whole. As a non-limiting example and as depicted in
In a desired aspect, the shell 102 is formed of a translucent or transparent plastic corrugate that allows for printing on both the inside and outside of the shell 102. For example, printing on the inside of the shell 102 can be seen on the outside of the shell 102.
Further, the outer protective shell 102 is formed in any suitable shape and in any suitable manner to allow for containment of the insulation cage therein 104, a non-limiting example of which is the cube-shape as illustrated in
The doors 700 and 702 are securely closed using the door locking mechanism 706. The door locking mechanism 706 is any suitable mechanism or device that allows for selectively locking/unlocking two components together. As a non-limiting example, the door locking mechanism 706 is a ratcheting latch. In other words, the ratcheting latch spans the center closing seam 704 and pulls the seam tightly closed to seal the doors 700 and 702 in a closed position. Unlocking the ratcheting latch allows the front loading doors 700 and 702 to swing 708 open to allow access to the insulation cage contained therein.
In a desired aspect, the shell 102 includes a mechanism or device that allows a user to maintain the doors 700 and 702 in an open position. For example, open connectors 710 are affixed with the doors 700 and 702 and outer walls of the shell 102. Thus, when the doors 700 and 702 are swung 708 entirely open, the open connectors 710 engage with one another to maintain the doors 700 and 702 affixed against the side walls. The open connectors 710 are any suitable mechanism or device that allows for the doors 700 and 702 to be selectively maintained in an open position, non-limiting examples of which include magnets or hook and loop fasteners (e.g. Velcro™).
In an aspect in which the outer shell 102 is formed as a box-shape (e.g., cube-shape) with front loading doors 700 and 702, all of the wall edges are directly connected with another wall edge, with the exception of the front top 712 and front bottom 714 loading edges. For example, the top wall 716 of the shell 102 is connected with a side wall 718 along the length of a top, side-edge 720. Because of the lengthwise connection along the top, side-edge 720, the top, side-edge 720 becomes relatively rigid. However, if the outer shell 102 is formed of a material that is somewhat flexible (e.g., plastic corrugate), the front top 712 and front bottom 714 loading edges are not connected, with any other component along their entire lengths and, as such, are subject to flexion and deformation. To provide further stability/rigidity to the front top 712 and front bottom 714 loading edges, rigid trim assemblies 722 can be included that clip over the front top 712 and front bottom 714 loading edges to provide rigidity to said edges. As shown in
Referring again to
As noted above with respect to
The second part 902 includes a catch 920 formed to receive and lockingly engage with the clasp 916. For example, as the clasp portion 914 pivots downward, the clasp 916 is forced over and against the catch 920, thereby locking the clasp 916 against the catch 920. Notably, the elongated portion 912 serves to position the clasp portion 914 (and its clasp 916) more directly over the second part 902 (and its catch 920) and, in doing so, reduces the requisite radius of rotation 922 of the clasp portion 914. Because the radius of rotation 922 is decreased (in comparison to a clasp that did not include such an elongated portion 912), the clasp 916 provides a returning force 924 to the catch 920. In other words, in addition to simply locking, the clasp 916 forces the catch 920 back toward the first part 900. By forcing the catch 920 back toward the first part 900, the first and second doors 700 and 702 are further tightened against one another to form a tight closing seal there between.
Desirably, the Vessel includes a tamper proof latch system. The tamper proof latch system is any suitable mechanism or device that provides an indication/assurance to an end user (consumer) that the contents of the Vessel have not been tampered with during shipment. As a non-limiting example and as illustrated in
As noted above, the Vessel and its components are, in one aspect, designed for ease of shipping by common carriers. While the Vessel and its components can be formed in any size, shape, and dimension, desirably and in one aspect, the components are formed to meet the volumetric and weight requirements for low-cost shipping by common carriers. As a non-limiting example and per the shipping requirements of one carrier (i.e., FedEx), the volume (as measured from the exterior) must be less than 5,184 cubic inches to avoid excess size surcharges. In other words and per this non-limiting example, “dimensional weight” is applied to FedEx ground packages that are three cubic feet (5,184 cubic inches) or larger. To determine the volume, one must multiple the length of the Vessel, by its width and height. If the total is 5,184 cubic inches or greater, then one must calculate the dimensional weight of the Vessel by dividing the volume by 166 (for shipments within the U.S.) or 139 (for shipments to Canada). If the dimensional weight exceeds the actual weight, charges may be assessed based on the dimensional weight (now being referred to as a chargeable weight). If the chargeable weight exceeds 150 lbs., a prorated per-pound rate will be used. Dimensions of one-half inch or greater are rounded up to the next whole number, whereas dimensions less than one-half inch are rounded down. The final calculation is rounded up to the next whole pound.
Alternatively, if the Vessel measures less than 5,184 cubic inches, dimensional weight does not apply and shipping charges will be assessed based on actual weight. Therefore and as noted above, it is desirable (in this example) to form the Vessel so that its volume (as measured from its exterior) is less than 5,184 cubic inches (and desirably greater than 4,000 cubic inches). Thus, in one non-limiting example and referring again to
Also as noted above, the Vessel and its components are, in one aspect, reusable. For example and as addressed above, many of the components can be easily replaced if deemed damaged or broken. Replacing individual components (as opposed to the entire Vessel) reduces waste, provides for cost efficiencies, and is green (i.e., promotes environmental benefits and considerations). In addition to simply being replaceable, the Vessel can be formed of any suitable material that assists in reusability. For example, the Vessel and its components are formed of material that allows it to withstand the rigors of shipping and then, once returned, to be sanitized so that it can be re-used. As a non-limiting example, the Vessel and its components are formed of thermoplastics (ABS plastic), polyethylene, polypropylene, BPA-free materials, stamped aluminum and steel, urethane foam or alternative insulation materials, or any combination thereof. In essence and in one aspect, the Vessel and its components are desirably formed of stable, sealable, and/or sanitize-able materials that allow for sterilization and reuse.
In another aspect, the Vessel can be formed to have on-board sensing capabilities and/or analytics, such as electronic monitoring of the temperature in the Vessel, the contents and inventory of the Vessel, tamper and theft detection, etc. The Vessel can also be formed to have the capability to transmit the obtained data/information to a desired party via the Cloud or any other suitable transmission medium (e.g., Internet, Wifi, etc.). Thus, the Vessel can include any required sensors (e.g., temperature sensors, tilt sensor, GPS sensor, light sensor, etc.) and or components that allow for sensing and/or analytics of the status of the Vessel, a non-limiting example of which include temperature sensors communicatively connected with a microprocessor or chip and transmitter for analyzing and/or transmitting the relevant temperature data to a receiving party (through the Cloud, Internet, etc.). As another non-limiting example, a circuit can be completed when the doors of the Vessel are closed. When the doors are open, the circuit is broken, which is indicative of opening or tampering with the Vessel. Thus, in one aspect, the Vessel can include the relevant components to sense when the doors are open, with a micro-processor or other circuitry that is operable for analyzing and/or transmitting the data to the relevant party. As such and as can be appreciated by those skilled in the art, there are a variety of sensing and analytical features that can be incorporated into the Vessel which provide for remote monitoring and analysis of the status of the Vessel and its contents
In summary, described is a shipping Vessel that includes an outer protective shell 102, an internal insulation cage 104 with a closing lid 108 and a plurality of drawers 106. The drawers 106 and other components are specifically designed to provide for conductive and/or convective properties within the Vessel 100 to assist in maintaining items (e.g., food, etc.) at a desired temperature. Further, the food containers 520 and cold/hot sources (e.g., ice packs 550) are also designed to assist in the conductive and/or convective properties of the food shipping Vessel 100. Some non-limiting example advantages over the prior art include: (1) the ability to maintain desired temperatures (e.g., cold or hot) for a desired period of time (e.g., at least 36 hours) after the shipping Vessel 100 leaves the cold (or hot) chain (even when exposed to extreme temperatures, such as 95 degrees Fahrenheit); (2) the shipping Vessel 100 is designed to work within the existing logistics infrastructure, including but not limited to FedEx, United Parcel Service (UPS) and the United States Postal Service (USPS) to meet their volumetric and weight requirements for low-cost shipping; (3) the drawers 106 and containers are designed to separate and protect contents from trauma during transit; (4) the modular design allows for shipping a wide variety of contents; (5) the Vessel 100 is constructed with durable materials that can be re-used; (6) the materials and design allow for easy sanitization for reuse; (7) no tape or scissors are needed to seal or open the Vessel 100; and (8) the shipping Vessel 100 can accommodate food or other items destined to multiple consumers at one shipping location. Finally, it should be understood that the specific examples described and illustrated are provided as non-limiting examples of suitable aspects; however, the invention is not intended to be limited thereto as it can be modified as needed and is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
