STACKABLE RECEPTACLE FOR THE SHIPMENT OF GOODS

BACKGROUND
Field

The disclosure relates to the field of boxes and receptacles, and in particular, to reusable stackable receptacles used for shipping and organizing goods and items, including perishable foods. Also disclosed herein are methods of making said reusable stackable receptacles.

Description

An increasing demand for the shipment of goods, including perishable goods, presents the problem of efficiently delivering these goods. In particular, it is difficult to deliver such goods without damaging the goods within the box. Perishable goods in particular are difficult to ship because of the need to adequately control the environment inside the shipping container, such as the temperature.

In addition to the difficulty of protecting the goods located in the boxes, there is the added problem of protecting the shipping box itself. For the shipment of perishable goods, in particular, it is sometimes commonplace to reuse the shipping container. Many goods, including perishable items, release moisture or create condensation, which penetrates the shipping container, resulting in a rapid breakdown of the shipping container such that it is unfit for reuse. Other goods soil the shipping container such that it would be unfit for reuse without first cleaning the container. In addition, the nature of reusing shipping containers presents the problem of damaging the boxes as a result of the constant handling and reuse.

Because the shipment of goods, including perishable foods, is ever increasing, it is increasingly necessary to organize the individual items within a suitable container, and to further organize the mass of orders. Typically, such organization is performed through stacking. However, many shipping boxes are unable to adequately stack in such a manner that the goods inside are sufficiently protected and the stacked boxes themselves are stacked in a stable manner.

To fold the box 100 into the closed position, as shown in FIG. 1B, the front flap 115 and the rear flap 155 are folded down into the interior of the box 100 along a score line or fold which attached the front and rear faces 110 and 150 to the front and rear flaps 115 and 155. The front support slot 114 and the rear support slot 154 face interior portion of the box 100, and are configured in size, shape, and location for insertion of the front support tab 145 and the rear support tab 146. The front elongated handle openings 113 and 116 align, such that the elongated handle openings 113 and 116 form a void extending through the front face 110 and the front flap 115, and creating a handle grip along the front face 110. Similarly, the rear elongated handle openings 153 and 156 align, providing a handle grip along the rear face 150.

The first assembly tab 121 and a second assembly tab 123 are inserted into the first assembly slot 120 and the second assembly slot 122, respectively, such that the first and second assembly tabs 121, 123 extend into and at least partially through the first and second assembly slots 120, 122. The first and second assembly tabs 121 and 123 are sized and shaped to be releasably retained in the first and second assembly slots 120, 122, such that the front flap 115 is maintained folded into the interior of the box and is maintained substantially parallel and/or in contact with at least a portion of the front face 110. The third and fourth assembly tabs 125, 127 are similarly inserted into third and fourth assembly slots 124, 126, thereby releasably retaining the rear flap 155 substantially parallel to the rear face 150 and/or at least partially in contact with the rear face 150.

The second segment 177 is folded down to contact and/or be substantially parallel to an inner surface of the second side face 170 such that the second segment 177 extends down along the interior surface of the second side face 170 substantially parallel to the second side face 170. The second side flap 175 is folded or bent along score line 179 to extend outward across the opening of the box 100, the second side flap 175 being substantially perpendicular to the second side face 170. The first support tabs (not shown) are inserted into the first support slots 134 formed in the first side face 130, similar to the tabs and slots described elsewhere herein. By inserting the first support tabs into the first support slots 134, the second side flap 175 is releasably maintained substantially perpendicular to the second side face 170 and substantially parallel to the bottom of the box 100. The cooperation of the first support tabs and the first support slots 134 allow the second side flap 175 to bear weight, such as the weight of a second box 100 placed on top of the first box 100.

The first side flap 135 is then folded into the interior of the box 100 such that the first segment 137 extends down into the interior of the box 100, at least partially in contact with or substantially parallel to an inner surface of the first side face 130. The first side flap 135 and the first segment 137 are folded along the score line 139, and the first side flap 135 is extended outward along the top of the second side flap 175, such that it is substantially parallel with the second side flap 175 and/or at least partially in contact with the second side flap 175, and substantially perpendicular to the first side face 130. The second support tabs 144 are inserted into second support slots 174 similar to those described elsewhere herein. The front support tab 145 is inserted into the front support slot 114, and the rear support tab 146 is inserted into the rear support slot 154. As depicted, the front and rear support tabs 145 and 146 do not extend through the front face 110 and the rear face 150, as the front face 100 and the rear face 150 do not have corresponding openings. In some embodiments, the front face 110 and the rear face 150 have openings corresponding to the front and rear support tabs 145 and 146 such that the front and rear support tabs 145, 146 extend through and are visible outside the box 100.

In the closed position, the combination of the first side flap 135 and the second side flap 170 form a surface on which items, such as other boxes 100 can be received and stacked. In the assembled, upright, closed position, the box 100 also has a lip or rim which can extend around a bottom portion of another box 100 stacked thereon.

Those of skill in the art will recognize that the taper of the box 100, or in other words, that the bottom portion of the box 100 is smaller than the top portion of the box, allows for stacking multiple boxes 100 together. such that the bottom portion of one box is capable of sitting in the top portion of a closed box. The top portion of the box has a greater area than the bottom portion of the box. Because the top portion of the box is larger than the bottom portion, the front face 110, rear face 150, first side face 130, and second side face 170 are not exactly perpendicular with the bottom of the box 100. Although the faces are substantially perpendicular, a slight angle is required in order to generate the taper. In some embodiments, the taper of the box can be defined by the algorithm. The taper of the box is set such that the inner surface of the rim or lip of the closed box corresponds to the dimensions of the outside of a bottom perimeter of the closed box, such that when one box 100 is inserted into the recess of another box 100, the inner surface of the rim or lip of the first box 100 mates with the outer diameter of the bottom portion of the second box 100 and creates a friction fit, to securely and releasably hold the boxes 100 together.

The second side flap 375 comprises first support tabs 384, second support slots 374, and a second finger slot 376. The second support slots 374 are located along a score line 379 that runs the length of the second flap 375, and which creates a second segment 377, which is attached to the second side face 370 along one length and the second side flap 375 along the opposite length.

Also provided herein are methods of assembling the reusable stackable shipping box. The method is provided wherein a flattened unitary piece of material is provided, and the user folds the material into a box. Alternatively, separate portions and segments are provided, and the portions may be united by attachments means, including, for example, glue, tape, or staples. The method further provides an assembled box, wherein the user places goods with the box, and the user closes the box such the box is capable of stacking upon other boxes or of being stacked upon in a stable manner and concomitantly protecting the goods contained therein.

For assembly of the stackable shipping box 300 of FIG. 3A, the user takes the manufacturer's joint 394 located on fourth segment 309 and attaches it to first segment 309, along the front face 310. In some embodiments, the manufacturer's joint 394 is attached to a surface of the front face 310 which faces the interior volume of the box 300 when the box is assembled. The joint 394 may be joined with adhesive to first segment 309, or alternatively may be stitched, stapled, or taped. One of skill in the art will recognize that the joint 394 may be attached to first segment 309 by attachment means, as previously described herein. Attachment of the manufacturer's joint 394 to first segment 309 creates a four sided box, with each of segments 309, 329, 349, and 369 making a side of the box. The first through fourth bottom folds 311, 331, 351, and 371 are demarcated from their respective faces with score lines. The first through fourth bottom folds 311, 331, 351, and 371 are folded up along the length of the score lines in an interlocking manner to create the bottom of the box. One of skill in the art will recognize that the bottom folds are configured in size and shape for efficient folding together to create a supportive bottom or floor of the box, and could by any number of suitable configurations, including the configuration as disclosed in the embodiment shown by FIG. 3A.

The front flap 315 and the rear flap 355 are demarcated from their respective faces with score lines. The front flap 315 is folded down along the length of the score line to the interior of the box 300, such that the front flap 315 sits parallel with the inside surface of the front face 310. Similarly, the rear flap 355 is folded down along the length of the score line to the interior of the box 300, such that the rear flap 355 sits parallel with the inside surface of the rear face 350. First assembly tab 321 is configured in size, shape, and location for placement into first assembly slot 320 upon folding of the front flap 315 down into the box 300. Similarly, second assembly tab 323, third assembly tab 325, and fourth assembly tab 327 are configured in size, shape, and location for insertion into second assembly slot 322, third assembly slot 324, and fourth assembly slot 326, respectively. The second front elongated handle opening 316 aligns with the first front elongated handle opening 313, such that the opening extends entirely through both the front face 310 and the front flap 315. Similarly, the second rear elongated handle opening 356 aligns with the first rear elongated handle opening 353, such that the opening extends entirely through both the rear face 350 and the rear flap 355.

The first side flap 335 and the second side flap 375 are demarcated from their respective faces with score lines. The user may fold first and second flaps 335 and 375 down into the box 300 prior to packing the box. Alternatively, the user may pack the box 300 with goods prior to folding first and second flaps 335 and 375. After packing the box 300, the user folds the second segment 377 down into the box only to the score line 379, such that the second segment 377 sits flush with, and parallel to the inside surface of second side face 370. For example, the second segment 377 may be folded along the top edge of the second side face so the second segment 377 is folded through an angle of approximately 180°. The second side flap 375 is folded along score line 379 to extend across the opening of the box 300, whereupon the first support tabs 384 are placed into the first support slots 334 that are located on the first side face 330. The second side flap 375 can be folded to be positioned at an angle of approximately 90° relative to the surface of the second segment and the second side face. The first side flap 335 is then folded down along a top edge of the first side face into the box only to the score line 339, such that the first segment 337 sits flush with, and parallel to the inward facing surface of the first side face 330. For example, the first segment 337 is folded down to through an angle of approximately 180° relative to the first side face 330. The first side flap 335 then is folded along the score line 339 such that the first side flap 335 extends across the second side flap 375, such that it sits flush with, and parallel to the second side flap 375, whereupon the second support tabs 344 are inserted into the second support slots 374 on the second side flap 375. The front support tab 345 is inserted into the front support slot 314, and the rear support tab 346 is inserted into the rear support slot 354. This configuration provides for a strong top support that is parallel to the bottom of the box, such that the goods located inside the box 300 do not become damaged. In addition, because the first segment 337 and the second segment 377 extend down into the interior of the box, the first and second side flaps 335 and 375 create a recessed top of the box 300, creating a lip around the top of the box 300 that allows for other stackable boxes to be placed upon the lid of the packaged box in a stable manner. As described previously, the box is slightly tapered, such that the top of the box is slightly larger than the bottom of the box, whereby the size of the open support region supports dimensions of the bottom of a box.

In some embodiments of the reusable box, the box 300 is provided wherein the length (L) of the unassembled flattened box is 60.226 inches and the height (H) is 42.058 inches. In some embodiments, L is 80.329 inches, and H is 50.289 inches. One of skill in the art will recognize that the aforementioned dimensions are for illustrative purposes only, and that any number of dimensions, sizes, and shapes can be realized within the scope of the disclosure provided herein.

By way of example, the bottom can be an auto-lock bottom box, a 1-2-3 bottom box, or any other box bottom. FIG. 3B depicts an top view of an embodiment of a reusable box 300 having an auto-lock bottom shown in an un assembled state. The reusable box 300 comprises first, second, third, and fourth segments 309, 329, 349, 369 as described elsewhere herein. First segment 309 comprises first bottom fold 311, which, in turn, comprises first attachment portion 311a. The first attachment portion 311a may comprise an adhesive or other attachment mechanism. The second segment 329 comprises second bottom fold 331, which, in turn, comprises second attachment area 331a. The second bottom fold 331 also includes a first tab 331b and a first tab notch 331c. The second attachment area 331 may comprise an adhesive on an underside of the attachment area 311a, or may comprise another attachment mechanism. When the box 300 is folded or assembled, the underside of the second attachment portion 331a is placed over and attaches to the first attachment area 311a using an adhesive, glue, tape, staple, or other similar attachment mechanism.

The third segment 349 comprises the third bottom fold 351, which comprises third attachment area 351a. The fourth segment comprises fourth bottom fold 371, which comprises fourth attachment area 371a. The fourth bottom fold 371 also includes a second tab 371b, a second tab notch 371c, and a third tab notch 371d. Similar to first and second attachment areas 311a, 331a, fourth attachment area 371a is configured to cover and attach to third attachment area 351a when the box 300 is folded or assembled. The attachment at first and second attachment areas 311a and 331a, and at 351a and 371a, can be fixed attachments, such that the bottom folds which are attached do not separate. This allows attachment of the manufacturer's joint 394 as described elsewhere herein, and flattening of the box, by moving the first, second, third, and fourth bottom folds 311, 331, 351, 371 into the volume of the box 100. When moving the first, second, third, and fourth bottom folds 311, 331, 351, and 371 into the volume of the box 300, the second and fourth bottom folds bend along first and second score lines 331e, 371e to accommodate the attachment between the bottom folds as described herein.

When the box 300 is ready to be used, the box 300 is unflattened, the first, second, third, and forth bottom folds 311, 331, 351, 371 extend from the internal volume of the box by virtue of the attachment between attachment areas 311a and 331a, and 351a and 371a. As the box is assembled, the first tab 331b moves into the second tab notch 371c and the second tab 371b moves into the first tab notch 331c. The first tab 331b then further moves into third tab notch 371d, where the tab contacts an edge of the fourth bottom fold, contacts a second tab 371b. The second tab 371b contacts an edge of the second bottom fold 331.

FIG. 3C shows a bottom view of an embodiment of the box 300 of FIG. 3B in an assembled state with the first and second attachment areas 311a, 331a attached to each other, third and fourth attachment areas 351a, 371a attached to each other, first tab 331b inserted into second tab notch 371c and third tab notch 371d, and second tab 371b inserted into first tab notch 331c.

FIG. 4A illustrates a perspective view of two stacked boxes of one embodiment of the reusable box, wherein the stackable feature of the stackable shipping boxes is illustrated. In this embodiment, a first upright, assembled, closed stackable shipping box 400 is placed upon a second upright, assembled, closed stackable shipping box 410. Box 400 is stacked upon box 410, such that the bottom portion of box 400 is recessed down into box 410, within the lip region. Dashed lines 420 on box 410 illustrate the lip region upon which box 400 is stacked, and further illustrates that shipping box 400 is placed somewhat within the top portion of shipping box 410, thereby creating a stable stacking position.

In this illustration, shipping box 400 is also closed with the flaps creating a lid and platform, to illustrate a rim 415 that is created upon folding the flaps downward into the box. The flaps create a supportive lid 435, thereby protecting the goods within the box. The configuration of the flaps also provides for a rim 415 within which other boxes may be stacked. One of skill in the art will recognize that for the stacking configuration to take place, the boxes may be tapered in shape, such that the bottom portion of the box is somewhat smaller than the upper portion of the box. Thus, a smaller bottom of one box is capable of stacking within the larger upper portion of another box, as described previously.

Certain embodiments of the reusable box include boxes wherein upon assembly, the boxes are tapered in configuration. Such tapering allows the boxes to readily stack one within the other, such that the bottom of the box is slightly smaller than the top of the box. Thus, the smaller bottom of one box can fit within the larger recessed top of another packed box. In one embodiment, the tapering of the box follows the algorithm, as previously described elsewhere herein.

FIG. 4B illustrates a side cutaway view of one embodiment of the stackable shipping box 410 taken along line 4B-4B to illustrate one embodiment of the inside of the box in the assembled position. In this embodiment, box 410 comprises three main compartments: a frozen compartment 411; a chilled compartment 412; and an ambient compartment 413. The frozen compartment 411 is configured in size and shape for the placement of a cooler, a bag, or a receptacle, that may contain frozen goods. Alternatively, the frozen goods may be placed directly into the box 410, with the addition of ice, dry ice, gel packs, or other elements used to maintain cold temperatures. Frozen goods may include, for example, frozen meats, frozen vegetables and fruits, or frozen dairy products. The chilled compartment 412 is located on the bottom of the box 410 and is configured in size and shape for the placement of a container containing chilled goods. Chilled goods may include, for example, dairy products and other perishable items that require chilling. The ambient compartment 413 is configured in size and shape for the placement of goods, such as non-perishable goods that do not demand any particular temperature requirements. Ambient items may include, for example, canned goods, electronic goods, or other goods fit for shipment in ambient temperature. In this embodiment, a divider 414 may be provided to separate the various compartments and to keep the contents securely in place.

The divider 414 can be a separate unit that can be placed within the box 410 after assembly of the box, and for the purpose of providing separate compartments for the shipment of goods. In some embodiments, the divider 414 can be integrated into the box 410, or can be fixedly attached within the box 410. The divider 414 comprises a vertical portion and a shelf portion. The shelf portion is moveably attached to the vertical portion, and can be folded to be parallel to the vertical position, or can be moved to be perpendicular to the vertical portion. The shelf portion comprises a horizontal portion and a support portion. When the divider 414 is inserted into the receptacle the shelf portion can be folded down from a vertical position to position the horizontal portion of the shelf portion perpendicular to the vertical portion, and the support portion of the shelf portion will extend perpendicular to the horizontal portion and parallel to the vertical portion. The support portion acts like a table leg or chair leg to support the horizontal portion, and to allow the shelf portion to support the weight of an object placed thereon. By folding the shelf portion into position (as shown), the internal volume of the box 410 is divided into the three illustrated portions, including the frozen compartment 411, the chilled compartment 412, and the ambient compartment 413.

In some embodiments, the frozen compartment 411 can be defined by an insulating box or insulating insert configured to fit within at least a portion of the receptacle 400. The insulating box or insert can have at least one vertical wall which can form the vertical portion of the divider 414. The shelf portion can be a separate piece comprising a horizontal portion and a support portion. The support portions can extend vertically to the horizontal portion to provide support for the horizontal portion, to allow the shelf portion to form a compartment below the horizontal portion, such as the chilled compartment 412, and to receive objects on the horizontal portion, such as in the ambient compartment 413.

Those of skill in the art will readily recognize that the embodiment described in FIG. 4B is exemplary only, and that many and various embodiments can be realized with various modifications of the descriptions provided herein.

FIG. 5 is a perspective view of one embodiment of the shipping box 500 as described herein. In this embodiment, the stackable shipping box 500 may be comprised of a suitable material for the construction of boxes, such as, for example, corrugated fiberboard, paperboard, plastics, polymers, and recycled materials. Corrugated fiberboard may comprise three main layers: two flat linerboards with fluted medium between the linerboards. The choice of the material for the fluted medium and for the linerboards can vary depending on the various applications and requirements for strength, but generally are manufactured with paper. The linerboards can be single-walled, double-walled, or triple-walled, depending on the various applications or requirements of strength and robustness. In some embodiments, the corrugated fiberboard comprises a first linerboard 505, a second linerboard 510, and a fluted medium 515.

In some embodiments, the corrugated fiberboard, paperboard, or other box material further comprises a layer of water- and grease-resistant coating 520. The water- and grease-resistant coating can be, for example, a polymer. One example of a polymer that is water- and grease-resistant is Micryl™ 766RN, which may be applied to one or both of the first and second linerboards 505 and 510. Another example of water- and grease-resistant material is a closed-cell foam, which not only provides water- and grease-resistance, but also helps insulate the shipping receptacle. The water- and grease-resistance coating 520 may be applied to or integrated with the corrugated fiberboard, which prevents the assembled stackable shipping box from soaking up liquid and condensation as is common with the shipment of perishable goods. In addition, the water- and grease-resistance coating 520 enables a user to readily clean the box prior to reuse without the prospect of damaging the box in the process of cleaning. The water- and grease-resistance coating 520 is applied or integrated by various means, but by way of illustration only, the material may be laminated or glued onto the corrugated fiberboard. In particular, the water- and grease-resistance coating 520 may be gluable with cold set and hot melt adhesives.

As one of skill in the art recognizes, containers for the shipment of perishable goods are commonly reused. The shipment of perishable goods frequently soils the shipping containers. In order to prepare the container for reuse, the shipping company must first clean the container. However, certain materials are not amendable for cleaning, such as cleaning by water, because the material readily breaks down. Corrugated fiberboard comprised of paper is not capable of withstanding the cleaning process without breaking down. However, the placement of the water- and grease-resistance coating 520 on the corrugated fiberboard surface assists in the ease of cleaning and also enables the container itself to withstand the cleaning process and thereby become suitable for reuse. In some embodiments of the reusable box, the box having a water- and grease-resistant coating applied thereon is recyclable.

The above description discloses several embodiments and materials a reusable box. This reusable box is susceptible to modifications and alterations in the embodiments. Such modifications will become apparent to those skilled in the art from consideration of this disclosure or practice of the reusable box disclosed herein. Consequently, it is not intended that this reusable box be limited to the specific embodiments disclosed herein, but that it cover all modifications and alternatives coming within the true scope and spirit of the reusable box as embodied in the attached claims.

The foregoing description details certain embodiments of the systems, devices, and methods disclosed herein. It will be appreciated, however, that no matter how detailed the foregoing appears in text, the systems, devices, and methods can be practiced in many ways. As is also stated above, it should be noted that the use of particular terminology when describing certain features or aspects of the invention should not be taken to imply that the terminology is being re-defined herein to be restricted to including any specific characteristics of the features or aspects of the technology with which that terminology is associated.

It will be appreciated by those skilled in the art that various modifications and changes may be made without departing from the scope of the described technology. Such modifications and changes are intended to fall within the scope of the embodiments. It will also be appreciated by those of skill in the art that parts included in one embodiment are interchangeable with other embodiments; one or more parts from a depicted embodiment can be included with other depicted embodiments in any combination. For example, any of the various components described herein and/or depicted in the Figures may be combined, interchanged or excluded from other embodiments.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

All references cited herein are incorporated herein by reference in their entirety. To the extent publications and patents or patent applications incorporated by reference contradict the disclosure contained in the specification, the specification is intended to supersede and/or take precedence over any such contradictory material.

The term “comprising” as used herein is synonymous with “including,” “containing,” or “characterized by,” and is inclusive or open-ended and does not exclude additional, unrecited elements or method steps.

The above description discloses several methods and materials of the present invention. This invention is susceptible to modifications in the methods and materials, as well as alterations in the fabrication methods and equipment. Such modifications will become apparent to those skilled in the art from a consideration of this disclosure or practice of the invention disclosed herein. Consequently, it is not intended that this invention be limited to the specific embodiments disclosed herein, but that it cover all modifications and alternatives coming within the true scope and spirit of the invention as embodied in the attached claims.
