Hardened Reusable Shipper

This application is based upon and claims the benefit of and priority to U.S. Provisional Patent Application No. 63/570,139 entitled “HARDENED REUSABLE SHIPPER,” filed on Mar. 26, 2024, the entire content of which is incorporated by reference herein.

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

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.

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. The strengthening face may have a base floor parallel to the lid when the lid is closed. The strengthening face may have an inset wall providing a central region of the base surrounded by the base floor and inset toward the lid relative to the base floor. The inset wall spaces the dewar received in the inner compartment away from the base floor so that the base elevates the dewar away from the base floor. The elevating of the dewar away from the base floor may at least partially mechanically isolate the dewar from direct vibratory conduction from a resting surface under the base.

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, various views of a shipperare depicted. The shippermay be a container having a shape suitable for air freight shipment and configured to receive a dewar therein. The shippermay be rectangular, or square, or rectilinear. The shippermay be trapezoidal or any suitable shape. The shippermay 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, 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 shippermay be stackable. The shippermay resist rolling or toppling. The shippermay be made of plastic, metal, or another suitable material to provide desired rigidity, flexibility, or other material properties.

In various embodiments, the shipperhas a lidand a base. The basemay comprise a larger body of the shipperand may be structured to secure a dewar therein. The lidmay comprise a smaller body of the shipperand may be removably couplable and/or hingably coupled to the baseto selectably close the baseto selectably enclose the dewar secured therein.

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

The shippermay have one or more wheel. The shippermay have two wheelsor four wheelsor any number of wheels. The wheelmay be a rolling apparatus to facilitate easy movement of the shipper. In various embodiments, two wheelsare attached to the shipperand are biased toward a same face of the shipperto facilitate rolling when the shipperis tilted toward the wheels, and to resist rolling when the shipperis tilted away from the wheelsto rest on the baseof the shipper.

The shippermay have a detachable plate. The detachable platemay 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. The detachable platemay be removable for cleaning. In various embodiments, the detachable platecomprises bent sheet metal shaped to protect at least a portion of the handlefrom inadvertent contact when in the inward position for storage.

The shippermay have one or more latch. The latchmay be an apparatus configured to effectuate selectable closure of a combination of the lidand the base. The shippermay have two latchesspaced apart on a front of the baseand selectably engageable to corresponding aspects near an edge of the lid. The latchesmay include clips, buckles, ties, hooks, or any other latch configuration.

The shippermay have a shipping label. 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 labelmay be a conventional adhesive shipping label.

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

The lidmay include a front registration boss. The front registration bossmay be a boss (e.g., a raised surface feature) extending upwardly (in direction) away from the lidon an upper side of the lidwhen the lidis closed. The front registration bossmay be biased toward one side of the shipper(e.g., a front sideof the shipper). The front registration bossmay facilitate alignment of another shipperwhen the other shipperis stacked on top of the lidfor storage or transportation. The boss may interact with a corresponding feature on a bottom of a baseof the other shipperso that the shippermore securely rests in place atop the front registration boss.

Similarly, the lidmay have a rear registration boss. A rear registration bossmay be a boss (e.g., a raised surface feature) extending upwardly (in direction) away from the lidon an upper side of the lidwhen the lidis closed. The rear registration bossmay be biased toward one side of the shipper(e.g., a rear sideof the shipper). The rear registration bossmay be biased toward an opposite side of the shipperthan the front registration boss(e.g., rear sideis opposite of front side). The rear registration bossmay facilitate alignment of another shipperwhen the other shipperis stacked on top of the lidfor storage or transportation. The boss may interact with a corresponding feature on a bottom of a baseof the other shipperso that the shippermore securely rests in place atop the rear registration boss.

The front registration bossand the rear registration bossmay each have various features. For instance, the front registration bossmay have a front primary ramp portionthat ramps away from the lidupwardly (in direction) a greater and greater distance from an origin point at the front primary ramp portion terminusto a highest point at the front bend portion. The front bend portionmay be a curved portion of the front registration bosswhere the boss curves from a first directiontoward a second direction. For instance, the front registration bossmay run parallel to an edge of the lid(or in any other direction) along the front primary ramp portion(e.g., in first direction), then may run in a changing direction (e.g., curving) along the front bend portion, and may then run in a second direction, such as being parallel to a different edge of the lid(or in any other direction) along a front secondary ramp portion. The front secondary ramp portionmay ramp away from the lidupwardly (in direction) a greater and greater distance from an origin point at a front secondary ramp portion terminusto the highest point at the front bend portion.

The rear registration bossmay have a rear primary ramp portionthat ramps away from the lidupwardly (in direction) a greater and greater distance from an origin point at the rear primary ramp portion terminusto a highest point at the rear bend portion. The rear bend portionmay be a curved portion of the rear registration bosswhere the boss curves from a direction toward another direction. For instance, the rear registration bossmay run parallel to an edge of the lid(or in any other direction) along the rear primary ramp portion(e.g., in first direction), then may run in a changing direction (e.g., curving) along the rear bend portion, and may then run in another direction, such as being parallel to a different edge of the lid(or in any other direction) along a rear secondary ramp portion(e.g., in second direction). The rear secondary ramp portionmay ramp away from the lidupwardly (in direction) a greater and greater distance from an origin point at a rear secondary ramp portion terminusto the highest point at the rear bend portion.

The front registration bossand the rear registration bossmay cooperate to orient and secure a further shipperstacked on top of the lidfor storage or transportation. For instance, the following discussion will detail example configurations of the front registration bossand the rear registration boss. Then, the discussion will detail example cooperating features of the front registration bossand the rear registration boss.

For instance, in various embodiments, the lidcomprises a front registration bossto be received by an aspect of another shipperto permit stacking of shippers, the front registration bosscomprising a front primary ramp portionof increasing height away from the basein at least one dimension along a first direction. The front registration bossmay include a front bend portioncurving along a path of changing direction and a front secondary ramp portionof increasing height away from the basein at least the at least one dimension along a second direction. The front primary ramp portionextends from a front primary ramp portion terminusto the front bend portion. The front secondary ramp portionextends from a front secondary ramp portion terminusto the front bend portion. A height away from the baseof the front bend portionis a greatest height of any portion of the front registration bossaway from the base, and the at least one registration boss (e.g., front registration boss) causes the shipperto wobble in response to the shipperbeing rested on the lidrather than on the base. Thus, the front registration bossmay also discourage improper positioning of the shipper, such as upside down positioning.

The lidmay include a rear registration bossspaced apart from the front registration bossand to be received by the aspect of another shipperto permit stacking of shippers. The rear registration bossmay include a rear primary ramp portionof increasing height away from the basein the at least one dimension along the first direction. The rear registration bossmay include a rear bend portioncurving along a path of changing direction. The rear registration bossmay include a rear secondary ramp portionof increasing height away from the basein at least the at least one dimension along the second direction. The rear primary ramp portionextends from a rear primary ramp portion terminusto the rear bend portion. The rear secondary ramp portionextends from a rear secondary ramp portion terminusto the rear bend portion. The height away from the baseof the rear bend portionis the greatest height any portion of the rear registration bossaway from the base. The rear registration bosscauses the shipperto wobble in response to the shipperbeing rested on the lidrather than on the base.

The front registration bossand the rear registration bosscooperate in various aspects. For instance, in various embodiments, the rear primary ramp portionand the front secondary ramp portionare parallel. In various embodiments, the rear secondary ramp portionand the front primary ramp portionare parallel. The rear bend portionand the front bend portionmay be a same size. The rear secondary ramp portionmay be smaller than the rear primary ramp portion. The rear primary ramp portionand the front primary ramp portionmay be of a first same size and the rear secondary ramp portionand the front secondary ramp portionmay be of a second same size, the second same size being smaller than the first same size.

Referring to bothand to, the lidincludes a lid sealing face. The lid sealing facemay be a face protruding from an underside of the lidto be received at least partially into a feature of the baseto enhance thermal sealing and to provide securement against inadvertent shearing away of the lidfrom the basewhen the lidis closed.

The lidmay include a dewar retention boss. While the dewar retention bossis shown as a disk in the figures, other shapes are also contemplated. The dewar retention bossmay comprise a compressible boss extending downwardly from an underside of the lidto rest against a dewar lidof a dewarbeing stored in the baseand press against the dewar lidof the dewar, compressing and securing the dewarfrom inadvertent movements or jostling. In various instances, the dewar retention bossmay be foam, or another compressible material.

Finally, the lidmay include a lid-side hinge portion. The lid-side hinge portionmay 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 portionon the base. Lid-side hinge portionmay interoperate with the base-side hinge portionto provide a hinge feature to allow hingable opening of the lidrelative to the base. Similarly, the basemay include a base-side hinge portion. The base-side hinge portionmay 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 portionon the lid. Base-side hinge portionmay interoperate with the lid-side hinge portionto provide a hinge feature to allow hingable opening of the lidrelative to the base.

Having introduced each aspect of the lid, attention is now directed tofor a discussion of the base. In various embodiments, the basecomprises one or more relief channelsdefined into one or more side of the base. A side of the base may be a face of the baseconnecting the front sideof the baseand the rear sideof the base. For example, a first sideis shown inand a second sideis shown in. An indentation may run along a portion of a side,of the baseand terminate at a ledge. The ledgemay be an abrupt end of the indentation, returning the side,of the baseto a generally rectangular geometry, thus providing a grasping surface for a hand to lift the shipperby grabbing the ledge. In various embodiments, the relief channelincludes an entry passageway, comprising an indentation running along at least a portion of a side,of the base, such as running from a bottom of the baseand at least partially up a side,of the basetoward the lid. The relief channelmay include a ledge, which comprises an ending of the entry passagewayto provide a grasping surface for lifting the shipper. In various embodiments, the relief channelis bound on each side of the relief channelby a guidance ramp. The guidance rampmay be angled, or curved, or may be normal to a bottom of the shipper. Thus, a pair of guidance ramps, and a ledgemay define the inner boundaries of the entry passageway. Two entry passagewaysmay be included, with each on opposite sides,of the baseto give space for two hands to grasp and maneuver the shipper. In further instances, the relief channelmay be shaped to interface with a machine device for lifting and moving the shipper.

As mentioned previously, the shippermay have one or more latch. Each latchmay be disposed in a corresponding latch channelof the base. A latch channelmay comprise a depression, local indentation, and or the like. The latch channelmay provide relief space to dispose a latchin connection to the baseand of use in securing the lidbut may provide protection to the latchfrom inadvertent contact, impact, and/or the like as the shipperis moved about.

The shippermay further include a surface feature channel. A surface feature channelmay comprise a channel to provide relief space for a handleand for a detachable plate. In this manner, the surface feature channelprovides relief space to dispose the handleand the detachable plateparallel to a profile of the baseor inset relative to the profile of the baseto provide protection from inadvertent contact, impact, and/or the like as the shipperis moved about.

Directing attention now to, the basemay further include an inner compartment. The inner compartmentmay be a cavity defined inside the baseand enclosable by a combination of the baseand the lid. An inner compartment wallof the basemay define the inner compartment.

The inner compartmentmay have various features. For instance, the inner compartmentmay have an inner compartment sealing ridge. The inner compartment sealing ridgemay be a local raised feature extending around a perimeter of an opening into the inner compartmentand structured to interface with one or more corresponding feature of the lid. The inner compartment sealing ridgemay extend at least partially into the lidon an underside of the lidto ameliorate any unwanted shearing of the lidrelative to the baseduring rough handling of the shipper. The inner compartment sealing ridgemay further provide enhanced thermal sealing, restricting gas or heat transfer through the area where the lidand the baseopen and close. In various embodiments, the inner compartmentalso includes an inner compartment sealing face. The inner compartment sealing facecomprises a face of the inner compartment sealing ridgethat contacts against the lid. For example, an outer perimeter face of the inner compartment sealing ridgethat is an outward-most face of the inner compartment sealing ridgerelative to the inner compartment wallmay be the inner compartment sealing face.

With reference to, the inner compartmentmay include document compartment. The document compartmentmay be a separate container defined by a document compartment wall. The document compartmentmay be inserted into the inner compartmentand may provide a separated area to secure documents inside of the inner compartment. Thus, a basemay comprise a document compartment walldefining a document compartmentwithin the inner compartment, the document compartmentdefining a subsection of the inner compartment.also illustrates a top profile viewof the document compartment, such as a lid of the document compartment and a bottom profile viewof the document compartment such as a floor of the document compartment.

Turning now to, in various embodiments, the inner compartmentfurther includes a foam stabilization block system. The foam stabilization block systemincludes one or more foam blocksto stabilize a dewarin the inner compartment. The foam blocksmay occupy space between a vesselof the dewarand an inner compartment wallof the inner compartment. In various embodiments, different foam blocksof different shapes may be implemented. For instance, because dimensions of the inner compartment walland of the dewarmay be different at different locations, the dimensions of the foam blocksmay also need to vary to appropriately occupy space in the inner compartmentto limit jostling and movement of the dewar. For instance, three foam blocksmay be inserted, though any other number may be contemplated. Each foam blockmay have an outer profile edgecomprising a surface of the foam blockthat contacts the inner compartment walland may have an inner profile edgecomprising a surface of the foam blockthat contacts the dewar, such as the vesselof the dewar. Thus, the shippermay include a foam stabilization block systemcomprising a plurality of foam blocksinserted into the inner compartment, each foam blockof the plurality of foam blockshaving an outer profile edgecorresponding in shape to at least a portion of the inner compartment walland having an inner profile edgecorresponding in shape to at least a portion of the dewar.

Turning now to, but with periodic reference to, further aspects of the baseinclude various features of a bottom of the base. In earlier paragraphs, the front registration boss() and rear registration boss() of the lid() were detailed. These registration bosses may be received into corresponding depressions on a basewhen a baseof one shipperis stacked onto the lidof another shipper. For example, the basemay include a front registration depressionto receive a front registration boss. Similarly, the basemay include a rear registration depressionto receive a rear registration boss.

The front registration depressionmay include a front primary ramp receiver. The front primary ramp receivermay comprise an abutting surface shaped to abut against a front primary ramp portionof a front registration boss. Similarly, the front registration depressionmay include a front bent portion receiver. The front bent portion receivermay include an abutting surface shaped to abut against a front bend portion. Likewise, the front registration depressionmay include a front secondary ramp receiver. The front secondary ramp receivermay include an abutting surface shaped to abut against a front secondary ramp portionof the front registration boss.

The rear registration depressionmay include a rear primary ramp receiver. The rear primary ramp receivermay comprise an abutting surface shaped to abut against a rear primary ramp portionof a rear registration boss. Similarly, the rear registration depressionmay include a rear bent portion receiver. The rear bent portion receivermay include an abutting surface shaped to abut against a rear bend portion. Likewise, the rear registration depressionmay include a rear secondary ramp receiver. The rear secondary ramp receivermay include an abutting surface shaped to abut against a rear secondary ramp portionof the rear registration boss.

The basemay include a strengthening face. The strengthening facemay comprise a group of features that strengthens a bottom of the base, such as by including beads, ribs, bends, and other strengthening geometry. Moreover, the strengthening facemay include beads, ribs, bends, and other strengthening geometry that also facilitates spacing and or securement of a dewarthat is inside an adjacent inner compartment() of the base.

The strengthening facemay comprise a base floor. The base floormay comprise a planar area. The base floormay be inset an inset distancetoward the lid() by an inset wallthat extends normal to the base floor. By insetting the base floor, a gap may be formed between a surface that the baserests on and a region of the basecorresponding to the base floor. This gap may provide for the front registration depressionand the rear registration depression. This gap may provide for further cushioning and/or isolation of a dewarinside the base, as will be discussed herein below. The strengthening facemay include an annular channel. The annular channelmay be a channel further inset relative to the base floorand extending from the base floor. The annular channelmay be a curved channel and may correspond to a shape of a similar curve on a bottom of a dewarthat rests inside the base. The annular channelmay join to a central recessdefined at a center of an annulus of the annular channel. The central recessmay comprise a planar feature parallel to the base floor. For example, a joining planemay fill the center of the annulus of the annular channel.

The annular channelmay have a variety of shapes. For example, the annular channelmay be a triangular channel (e.g., an annulus having a triangle cross-section). The annular channelmay be a trapezoidal channel (e.g., an annulus having a trapezoidal cross-section). The annular channelmay be an arcuate channel (e.g., an annulus having an arcuate cross-section). In some instances, the arcuate channel may have a cross-section that is a curve such as a portion of a circle. For example, the annular channelmay have an inward bend facethat bends inwardly toward a lid() of the shipper(), a basin facethat is an inward most portion of the annular channel, and an outward bend facethat bends outwardly in a direction at least partially opposite that of the inward bend faceand that connects the basin faceto the joining planeof the central recess.

Thus, with continuing reference to, reference to, as well as periodic reference to, a shipperconfigured to retain a dewarfor shipment may include a basecomprising an inner compartment walldefining an inner compartmentto receive the dewarand a lidselectably closable over the inner compartmentto secure the dewartherein. The basecomprises a strengthening faceopposite the lid, the strengthening facehaving a base floorparallel to the lidwhen the lidis closed and comprising an annular channeldefining an annular bead of the base floor. The annular channelmay include an inward bend facecomprising a first curved bend of the strengthening faceinwardly away from the base floorand into the inner compartment.

The annular channelmay also have a basin facecomprising an inwardmost floor of the annular channel. A tangent of the basin facemay be parallel to at least a portion of the base floor. The annular channelmay also have an outward bend facecomprising a second curved bend of the strengthening faceoutwardly from the basin faceand away from the inner compartmentand toward the base floor. The strengthening facefurther comprises a central recess, the central recesscomprising a joining planejoining all outermost points of the second curved bend. The joining planemay be a circle. The joining planemay be parallel to the base floorand nearer to the lidthan is 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 recessare all inset toward the lidby a inset wallsurrounding the base floorand extending normal to each of the lid, the base floor, and the joining plane, the surrounding inset walldefining a closed perimeter of the base floor, the base floordefining a closed perimeter of the annular channel, and the annular channeldefining a closed perimeter of the central recess.
