Description

BACKGROUND

1. Field

The various aspects and embodiments described herein relate to shipping containers, particularly hardened reusable shippers.

2. Description of the Related Art

In the health, medical, pharmaceutical, and/or life science industries, safe storage and fast transportation of payloads in a temperature-controlled and watertight environment is important. Hardened reusable shipping containers that maintain, regulate, or control the payload area temperature are desirable in transporting temperature sensitive payloads in such industries. The payload area temperature may be maintained by using phase change materials (e.g., dry ice) and/or cryogenic liquids (e.g., liquid nitrogen). Due to the temperature sensitive nature of the shipments, issues with shipping that lead to delivery delay may result in the payload being expired, spoiled, reduced quality, or damaged. Moreover, rough handling may result in the payload being damaged. As such, there is a need for a hardened reusable shipping container with improvements to enhance ruggedness, provide for easy display of shipping addresses, instructions, and payload-specific information to a handler, and discourage improper handling of the hardened reusable shipping container to mitigate or eliminate delivery delays and prevent damage to the payload.

SUMMARY

Hardened reusable shippers are disclosed herein. A shipper may be configured to retain a dewar for shipment. The shipper may include a base having an inner compartment wall defining an inner compartment to receive a dewar. The shipper may include a lid selectably closable over the inner compartment to secure the dewar therein. The lid may include a front registration boss to be received by an aspect of another shipper to permit stacking of shippers. The front registration boss may include a front primary ramp portion of increasing height away from the base in at least one dimension along a first direction, a front bend portion curving along a path of changing direction, and a front secondary ramp portion of increasing height away from the base in at least the at least one dimension along a second direction. The front primary ramp portion extends from a front primary ramp portion terminus to the front bend portion. The front secondary ramp portion extends from a front secondary ramp portion terminus to the front bend portion. A height away from the base of the front bend portion is a greatest height of any portion of the front registration boss away from the base. The at least one registration boss causes the shipper to wobble in response to the shipper being rested on the lid rather than on the base.

One or more further aspects may be included. For instance, the lid may include a rear registration boss spaced apart from the front registration boss and to be received by the aspect of the another shipper to permit stacking of shippers. The rear registration boss may include a rear primary ramp portion of increasing height away from the base in the at least one dimension along the first direction, a rear bend portion curving along a path of changing direction, and a rear secondary ramp portion of increasing height away from the base in at least the at least one dimension along the second direction. The rear primary ramp portion extends from a rear primary ramp portion terminus to the rear bend portion. The rear secondary ramp portion extends from a rear secondary ramp portion terminus to the rear bend portion. The height away from the base of the rear bend portion is the greatest height any portion of the rear registration boss away from the base. The rear registration boss causes the shipper to wobble in response to the shipper being rested on the lid rather than on the base.

In various embodiments, the rear primary ramp portion and the front primary ramp portion are parallel. In various embodiments, the rear secondary ramp portion and the front secondary ramp portion are parallel. The rear bend portion and the front bend portion may be a same size. The rear secondary ramp portion may be smaller than the rear primary ramp portion. The rear primary ramp portion and the front primary ramp portion may be of a first same size and the rear secondary ramp portion, and the front secondary ramp portion may be of a second same size, the second same size being smaller than the first same size.

In various embodiments, the base further includes a document compartment wall defining a document compartment within the inner compartment, the document compartment defining a subsection of the inner compartment. A foam stabilization block system may be provided. The foam stabilization block system may include a plurality of foam blocks inserted into the inner compartment, each foam block of the plurality of foam blocks having an outer profile edge corresponding in shape to at least a portion of the inner compartment wall and having an inner profile edge corresponding in shape to at least a portion of the dewar.

A shipper configured to retain a dewar for shipment is provided. The shipper may include a base having an inner compartment wall defining an inner compartment to receive the dewar. The shipper may include a lid selectably closable over the inner compartment to secure the dewar therein. The base may include a strengthening face opposite the lid. The strengthening face may have a base floor parallel to the lid when the lid is closed and having an annular channel defining an annular bead of the base floor. The annular channel may include an inward bend face providing a first curved bend of the strengthening face inwardly away from the base floor and into the inner compartment.

One or more further aspects may be included. The annular channel may have a basin face providing an inwardmost floor of the annular channel, a tangent of the basin face parallel to at least a portion of the base floor. The annular channel may include an outward bend face providing a second curved bend of the strengthening face outwardly from the basin face and away from the inner compartment and toward the base floor. The strengthening face may further include a central recess.

The central recess may provide a joining plane joining all outermost points of the second curved bend. The joining plane may be a circle. The joining plane may be parallel to the base floor and nearer to the lid than the base floor.

In various embodiments, (i) the base floor, (ii) the inward bend face, (iii) the basin face, (iv) the outward bend face, and (v) the central recess are all inset toward the lid by a inset wall surrounding the base floor and extending normal to each of the lid, the base floor, and the joining plane. The surrounding inset wall may define a closed perimeter of the base floor. The base floor may define a closed perimeter of the annular channel. The annular channel may define a closed perimeter of the central recess.

In various embodiments, the first curved bend has a profile corresponding to a profile of a portion of the dewar. The dewar is nestable against at least a portion of the strengthening face inside the inner compartment. In various embodiments, the first curved bend has a profile corresponding to a profile of a portion of the dewar and a distance between the dewar and the strengthening face measured in a direction normal to the strengthening face is a constant distance. A foam block may be received into the constant distance. The strengthening face may support the foam block. The foam block may support the dewar.

In various embodiments, a shipper is configured to retain a dewar for secure shipment. The shipper may include a base. The base may include an inner compartment wall defining an inner compartment to receive the dewar. The shipper may include a lid selectably closable over the inner compartment to secure the dewar therein. The base may have a strengthening face opposite the lid.

DETAILED DESCRIPTION

Disclosed herein are hardened reusable shipping containers (or “shippers”). The shippers may maintain, regulate, or control a temperature or a temperature range within a payload area. Systems including cryogenic liquids and/or phase change materials may be used in conjunction with the shippers to set or maintain the temperature inside the payload area at a desired temperature or temperature range. The desired temperature or temperature range may be a temperature or temperature range that preserves a payload within the payload area before, during, and/or after shipment. The shippers may be made from a hardened material (e.g., polycarbonate, polyethylene, etc.) that protects the payload from environmental factors including shock and vibration. Further, the shippers may be decontaminated and cleaned, thereby allowing reuse of the shippers.

Some of the shippers may maintain, regulate, or control the temperature or the temperature range within the payload area for a limited time. As such, swift delivery of the payload is important to prevent the temperature within the payload area from changing to an undesirable temperature or temperature range that may damage the payload. Errors such as mishandling or misdelivering the shippers may cause or contribute to delays in shipment, thus jeopardizing the payload. Shippers having features to facilitate easy review of shipping and handling information ameliorate errors. Shippers having features to enhance ruggedness and shippers having features to discourage improper handling also ameliorate damage.

Finally, airline procedures for airborne cargo limit the availability of shipping by air of conventional dewars or other vessels having non-rectilinear shapes. As such, development of a shipper that also exhibits a rectilinear shape and securely retains a dewar (which may have a shape disallowed for air cargo) may enhance the availability of air shipment and facilitate swift delivery to prevent undesirable temperature excursions and damage to the payload.

Referring now to FIGS. 1A-F, various views of a shipper 2 are depicted. The shipper 2 may be a container having a shape suitable for air freight shipment and configured to receive a dewar therein. The shipper 2 may be rectangular, or square, or rectilinear. The shipper 2 may be trapezoidal or any suitable shape. The shipper 2 may have surface features, channels, and cut outs to facilitate different functions and aspects. For instance, aspects that may protrude beyond an edge plane of the shipper 2, disrupting the shape (e.g., disrupting a rectilinear profile) may be placed in dents, impressions, channels, cutouts, and the like, to ameliorate disruption to the shape (e.g., the rectilinear profile). The shipper 2 may be stackable. The shipper 2 may resist rolling or toppling. The shipper 2 may be made of plastic, metal, or another suitable material to provide desired rigidity, flexibility, or other material properties.

In various embodiments, the shipper 2 has a lid 4 and a base 6. The base 6 may comprise a larger body of the shipper 2 and may be structured to secure a dewar therein. The lid 4 may comprise a smaller body of the shipper 2 and may be removably couplable and/or hingably coupled to the base 6 to selectably close the base 6 to selectably enclose the dewar secured therein.

The shipper 2 may have a handle 8. The handle 8 may be attached to a side of the base 6. In various embodiments, the handle 8 may be extendible, for example by telescoping outward for use by a person manipulating the shipper 2, then telescoping inward for storage.

The shipper 2 may have one or more wheel 10. The shipper 2 may have two wheels 10 or four wheels 10 or any number of wheels 10. The wheel 10 may be a rolling apparatus to facilitate easy movement of the shipper 2. In various embodiments, two wheels 10 are attached to the shipper 2 and are biased toward a same face of the shipper 2 to facilitate rolling when the shipper 2 is tilted toward the wheels 10, and to resist rolling when the shipper 2 is tilted away from the wheels 10 to rest on the base 6 of the shipper 2.

The shipper 2 may have a detachable plate 12. The detachable plate 12 may comprise a cleanable surface suitable for adherence by stickers. Labels, instructions, or other information may be printed on stickers and adhered to the detachable plate 12. The detachable plate 12 may be removable for cleaning. In various embodiments, the detachable plate 12 comprises bent sheet metal shaped to protect at least a portion of the handle 8 from inadvertent contact when in the inward position for storage.

The shipper 2 may have one or more latch 24. The latch 24 may be an apparatus configured to effectuate selectable closure of a combination of the lid 4 and the base 6. The shipper 2 may have two latches 24 spaced apart on a front of the base 6 and selectably engageable to corresponding aspects near an edge of the lid 4. The latches 24 may include clips, buckles, ties, hooks, or any other latch configuration.

The shipper 2 may have a shipping label 52. The shipping label may be an electronic label module. In various embodiments, an electronic display screen, such as an e-ink display provides shipping information, address labels, or the like. In further instances, the shipping label 52 may be a conventional adhesive shipping label.

Having generally introduced each feature of the shipper 2, attention is now directed to the lid 4 for a discussion of particular aspects of the lid 4. In various embodiments, a lid 4 may include a handle channel 26. A handle channel 26 may comprise a cut out, depression, or other relief structure to provide for unobstructed passage of the handle 8 between outwardly telescoped (extended) and inwardly telescoped (retracted) positions without requiring manipulation or opening or closing of the lid 4.

The lid 4 may include a front registration boss 28. The front registration boss 28 may be a boss (e.g., a raised surface feature) extending upwardly (in direction 506) away from the lid 4 on an upper side of the lid 4 when the lid 4 is closed. The front registration boss 28 may be biased toward one side of the shipper 2 (e.g., a front side 502 of the shipper 2). The front registration boss 28 may facilitate alignment of another shipper 2 when the other shipper 2 is stacked on top of the lid 4 for storage or transportation. The boss may interact with a corresponding feature on a bottom of a base 6 of the other shipper 2 so that the shipper 2 more securely rests in place atop the front registration boss 28.

Similarly, the lid 4 may have a rear registration boss 30. A rear registration boss 30 may be a boss (e.g., a raised surface feature) extending upwardly (in direction 506) away from the lid 4 on an upper side of the lid 4 when the lid 4 is closed. The rear registration boss 30 may be biased toward one side of the shipper 2 (e.g., a rear side 504 of the shipper 2). The rear registration boss 30 may be biased toward an opposite side of the shipper 2 than the front registration boss 28 (e.g., rear side 504 is opposite of front side 502). The rear registration boss 30 may facilitate alignment of another shipper 2 when the other shipper 2 is stacked on top of the lid 4 for storage or transportation. The boss may interact with a corresponding feature on a bottom of a base 6 of the other shipper 2 so that the shipper 2 more securely rests in place atop the rear registration boss 30.

The front registration boss 28 and the rear registration boss 30 may each have various features. For instance, the front registration boss 28 may have a front primary ramp portion 32 that ramps away from the lid 4 upwardly (in direction 506) a greater and greater distance from an origin point at the front primary ramp portion terminus 38 to a highest point at the front bend portion 34. The front bend portion 34 may be a curved portion of the front registration boss 28 where the boss curves from a first direction 508 toward a second direction. For instance, the front registration boss 28 may run parallel to an edge of the lid 4 (or in any other direction) along the front primary ramp portion 32 (e.g., in first direction 508), then may run in a changing direction (e.g., curving) along the front bend portion 34, and may then run in a second direction 510, such as being parallel to a different edge of the lid 4 (or in any other direction) along a front secondary ramp portion 36. The front secondary ramp portion 35 may ramp away from the lid 4 upwardly (in direction 506) a greater and greater distance from an origin point at a front secondary ramp portion terminus 40 to the highest point at the front bend portion 34.

The rear registration boss 30 may have a rear primary ramp portion 42 that ramps away from the lid 4 upwardly (in direction 506) a greater and greater distance from an origin point at the rear primary ramp portion terminus 48 to a highest point at the rear bend portion 44. The rear bend portion 44 may be a curved portion of the rear registration boss 30 where the boss curves from a direction toward another direction. For instance, the rear registration boss 30 may run parallel to an edge of the lid 4 (or in any other direction) along the rear primary ramp portion 42 (e.g., in first direction 508), then may run in a changing direction (e.g., curving) along the rear bend portion 44, and may then run in another direction, such as being parallel to a different edge of the lid 4 (or in any other direction) along a rear secondary ramp portion 46 (e.g., in second direction 510). The rear secondary ramp portion 46 may ramp away from the lid 4 upwardly (in direction 506) a greater and greater distance from an origin point at a rear secondary ramp portion terminus 50 to the highest point at the rear bend portion 44.

The front registration boss 28 and the rear registration boss 30 may cooperate to orient and secure a further shipper 2 stacked on top of the lid 4 for storage or transportation. For instance, the following discussion will detail example configurations of the front registration boss 28 and the rear registration boss 30. Then, the discussion will detail example cooperating features of the front registration boss 28 and the rear registration boss 30.

For instance, in various embodiments, the lid 4 comprises a front registration boss 28 to be received by an aspect of another shipper 2 to permit stacking of shippers, the front registration boss 28 comprising a front primary ramp portion 32 of increasing height away from the base 6 in at least one dimension along a first direction 508. The front registration boss 28 may include a front bend portion 34 curving along a path of changing direction and a front secondary ramp portion 36 of increasing height away from the base 6 in at least the at least one dimension along a second direction 510. The front primary ramp portion 32 extends from a front primary ramp portion terminus 38 to the front bend portion 34. The front secondary ramp portion 35 extends from a front secondary ramp portion terminus 40 to the front bend portion 34. A height away from the base 6 of the front bend portion 34 is a greatest height of any portion of the front registration boss 28 away from the base 6, and the at least one registration boss (e.g., front registration boss 28) causes the shipper 2 to wobble in response to the shipper 2 being rested on the lid 4 rather than on the base 6. Thus, the front registration boss 28 may also discourage improper positioning of the shipper 2, such as upside down positioning.

The lid 4 may include a rear registration boss 30 spaced apart from the front registration boss 28 and to be received by the aspect of another shipper 2 to permit stacking of shippers. The rear registration boss 30 may include a rear primary ramp portion 42 of increasing height away from the base 6 in the at least one dimension along the first direction 508. The rear registration boss 30 may include a rear bend portion 44 curving along a path of changing direction. The rear registration boss 30 may include a rear secondary ramp portion 46 of increasing height away from the base 6 in at least the at least one dimension along the second direction 510. The rear primary ramp portion 42 extends from a rear primary ramp portion terminus 48 to the rear bend portion 44. The rear secondary ramp portion 46 extends from a rear secondary ramp portion terminus 50 to the rear bend portion 44. The height away from the base 6 of the rear bend portion 44 is the greatest height any portion of the rear registration boss 30 away from the base 6. The rear registration boss 30 causes the shipper 2 to wobble in response to the shipper 2 being rested on the lid 4 rather than on the base 6.

The front registration boss 28 and the rear registration boss 30 cooperate in various aspects. For instance, in various embodiments, the rear primary ramp portion 42 and the front secondary ramp portion 36 are parallel. In various embodiments, the rear secondary ramp portion 46 and the front primary ramp portion 32 are parallel. The rear bend portion 44 and the front bend portion 34 may be a same size. The rear secondary ramp portion 46 may be smaller than the rear primary ramp portion 42. The rear primary ramp portion 42 and the front primary ramp portion 32 may be of a first same size and the rear secondary ramp portion 46 and the front secondary ramp portion 36 may be of a second same size, the second same size being smaller than the first same size.

Referring to both FIGS. 1A-1F and to FIG. 2, the lid 4 includes a lid sealing face 208. The lid sealing face 208 may be a face protruding from an underside of the lid 4 to be received at least partially into a feature of the base 6 to enhance thermal sealing and to provide securement against inadvertent shearing away of the lid 4 from the base 6 when the lid 4 is closed.

The lid 4 may include a dewar retention boss 210. While the dewar retention boss 210 is shown as a disk in the figures, other shapes are also contemplated. The dewar retention boss 210 may comprise a compressible boss extending downwardly from an underside of the lid 4 to rest against a dewar lid 226 of a dewar 218 being stored in the base 6 and press against the dewar lid 226 of the dewar 218, compressing and securing the dewar 218 from inadvertent movements or jostling. In various instances, the dewar retention boss 210 may be foam, or another compressible material.

Finally, the lid 4 may include a lid-side hinge portion 214. The lid-side hinge portion 214 may comprise a tab, or a hinge pin, or a hinge pin receiver, or another aspect of a hinge that corresponds to a base-side hinge portion 216 on the base 6. Lid-side hinge portion 214 may interoperate with the base-side hinge portion 216 to provide a hinge feature to allow hingable opening of the lid 4 relative to the base 6. Similarly, the base 6 may include a base-side hinge portion 216. The base-side hinge portion 216 may comprise a tab, or a hinge pin, or a hinge pin receiver, or another aspect of a hinge that corresponds to a lid-side hinge portion 214 on the lid 4. Base-side hinge portion 216 may interoperate with the lid-side hinge portion 214 to provide a hinge feature to allow hingable opening of the lid 4 relative to the base 6.

Having introduced each aspect of the lid 4, attention is now directed to FIGS. 1A-F for a discussion of the base 6. In various embodiments, the base 6 comprises one or more relief channels 14 defined into one or more side of the base 6. A side of the base may be a face of the base 6 connecting the front side 502 of the base 6 and the rear side 504 of the base 6. For example, a first side 512 is shown in FIG. 1B and a second side 514 is shown in FIG. 1C. An indentation may run along a portion of a side 512, 514 of the base 6 and terminate at a ledge 18. The ledge 18 may be an abrupt end of the indentation, returning the side 512, 514 of the base 6 to a generally rectangular geometry, thus providing a grasping surface for a hand to lift the shipper 2 by grabbing the ledge 18. In various embodiments, the relief channel 14 includes an entry passageway 16, comprising an indentation running along at least a portion of a side 512, 514 of the base 6, such as running from a bottom of the base 6 and at least partially up a side 512, 514 of the base 6 toward the lid 4. The relief channel 14 may include a ledge 18, which comprises an ending of the entry passageway 16 to provide a grasping surface for lifting the shipper 2. In various embodiments, the relief channel 14 is bound on each side of the relief channel 14 by a guidance ramp 20. The guidance ramp 20 may be angled, or curved, or may be normal to a bottom of the shipper 2. Thus, a pair of guidance ramps 20, and a ledge 18 may define the inner boundaries of the entry passageway 16. Two entry passageways 16 may be included, with each on opposite sides 512, 514 of the base 6 to give space for two hands to grasp and maneuver the shipper 2. In further instances, the relief channel 14 may be shaped to interface with a machine device for lifting and moving the shipper 2.

As mentioned previously, the shipper 2 may have one or more latch 24. Each latch 24 may be disposed in a corresponding latch channel 22 of the base 6. A latch channel 22 may comprise a depression, local indentation, and or the like. The latch channel 22 may provide relief space to dispose a latch 24 in connection to the base 6 and of use in securing the lid 4 but may provide protection to the latch 24 from inadvertent contact, impact, and/or the like as the shipper 2 is moved about.

The shipper 2 may further include a surface feature channel 54. A surface feature channel 54 may comprise a channel to provide relief space for a handle 8 and for a detachable plate 12. In this manner, the surface feature channel 54 provides relief space to dispose the handle 8 and the detachable plate 12 parallel to a profile of the base 6 or inset relative to the profile of the base 6 to provide protection from inadvertent contact, impact, and/or the like as the shipper 2 is moved about.

Directing attention now to FIG. 2, the base 6 may further include an inner compartment 200. The inner compartment 200 may be a cavity defined inside the base 6 and enclosable by a combination of the base 6 and the lid 4. An inner compartment wall 202 of the base 6 may define the inner compartment 200.

The inner compartment 200 may have various features. For instance, the inner compartment 200 may have an inner compartment sealing ridge 204. The inner compartment sealing ridge 204 may be a local raised feature extending around a perimeter of an opening into the inner compartment 200 and structured to interface with one or more corresponding feature of the lid 4. The inner compartment sealing ridge 204 may extend at least partially into the lid 4 on an underside of the lid 4 to ameliorate any unwanted shearing of the lid 4 relative to the base 6 during rough handling of the shipper 2. The inner compartment sealing ridge 204 may further provide enhanced thermal sealing, restricting gas or heat transfer through the area where the lid 4 and the base 6 open and close. In various embodiments, the inner compartment 200 also includes an inner compartment sealing face 206. The inner compartment sealing face 206 comprises a face of the inner compartment sealing ridge 204 that contacts against the lid 4. For example, an outer perimeter face of the inner compartment sealing ridge 204 that is an outward-most face of the inner compartment sealing ridge 204 relative to the inner compartment wall 202 may be the inner compartment sealing face 206.

With reference to FIGS. 2, 4, and 5, the inner compartment 200 may include document compartment 220. The document compartment 220 may be a separate container defined by a document compartment wall 222. The document compartment 220 may be inserted into the inner compartment 200 and may provide a separated area to secure documents inside of the inner compartment 200. Thus, a base 6 may comprise a document compartment wall 222 defining a document compartment 220 within the inner compartment 200, the document compartment 220 defining a subsection of the inner compartment 200. FIG. 5 also illustrates a top profile view 224 of the document compartment, such as a lid of the document compartment and a bottom profile view 223 of the document compartment such as a floor of the document compartment.

Turning now to FIGS. 2 and 3, in various embodiments, the inner compartment 200 further includes a foam stabilization block system 302. The foam stabilization block system 302 includes one or more foam blocks 304 to stabilize a dewar 218 in the inner compartment 200. The foam blocks 304 may occupy space between a vessel 224 of the dewar 218 and an inner compartment wall 202 of the inner compartment 200. In various embodiments, different foam blocks 304 of different shapes may be implemented. For instance, because dimensions of the inner compartment wall 202 and of the dewar 218 may be different at different locations, the dimensions of the foam blocks 304 may also need to vary to appropriately occupy space in the inner compartment 200 to limit jostling and movement of the dewar 218. For instance, three foam blocks 304 may be inserted, though any other number may be contemplated.
