Shock absorbing container and vibration isolator system

A container system including an outer shell, a deck disposed within the outer shell and configured to support cargo, and at least one vibration isolator member to support the deck within the outer shell and reduce or dampen a transfer of shock or vibration to the deck. Each vibration isolator member includes a hollow, flexible body configured to resiliently compress in response to a force. At least one fastener interface secures the flexible body to the bottom wall or to the deck. The hollow, flexible body has one or more apertures to allow fluid flow into and out of an inner cavity of the flexible body during compression or expansion.

BACKGROUND

The present disclosure relates generally to the field of containers including, but not limited to, shipping containers, storage containers, or containers used for other purposes. The present disclosure also relates to shock or vibration isolating systems for cargo. Specific examples relate to containers having shock or vibration isolating systems, configured to contain and protect cargo (one or more objects, items, goods, fragile or breakable articles, live cargo, biological cargo, or the like) within the container during transportation, storage or other activities.

Containers as described herein may be used in a variety of contexts, including, but not limited to transporting cargo (including any type of objects, items, goods, fragile or breakable articles, live cargo, biological cargo, tactical or explosive items, or the like) between locations (e.g., countries, cities, states, businesses, people, etc.), storing cargo, or holding or protecting cargo for other activities. Containers typically define an interior volume in which cargo can be held during transportation, storage or other activities. Different types and sizes of container structures may be used for different types of cargo, or for different contexts or applications of use. For example, certain containers for mass transportation of cargo may utilize inexpensive cardboard box structures to reduce costs, while certain containers for transportation of fragile or breakable cargo may utilize shock resistant structures contained in or configured on the containers.

Certain containers configured to reduce physical shock experienced by cargo may include one or more structures or features to dampen or otherwise reduce the transfer of physical shocks to cargo held within the container. In some examples, shock-dampening containers may include an outer shell structure, and a suspended deck or platform that hangs within an interior volume of the outer shell structure by a hanging suspension mechanism. The deck or platform may be configured to hold one or more articles or objects (cargo) within the interior volume of the outer shell. In some previous examples, a deck or platform has been suspended within a container shell, by hanging the deck or platform with multiple rubber bands or strap members, springs, or the like, that each have one end attached to the deck or platform and another end attached to the inner wall of the container shell. In such examples, the deck or platform may need to be made of a material or configuration that has a sufficient strength or rigidity (or both) to be suspended in a hanging manner by bands or straps (or springs). In addition, the bands, straps or springs can stretch or break over time or over multiple uses, reducing their ability to dampen shocks. Such bands, straps or springs may require replacement after a period of usage, and may include expiration dates or number-of-usage limits.

In this regard, shocks, bumps, accelerations, decelerations and other physical forces imparted on the outer shell of the container (for example, during transportation or handling of the container), can be dampened with respect to the suspended platform and cargo held by the suspended platform.

Referring toFIGS.1-20, an example container system, or container10(hereinafter referred to as container10) includes an outer shell11that defines an interior volume12. The container10also includes a deck or platform50and one or more (or a plurality of) flexible vibration isolator members100within the interior volume12. The deck or platform50is configured to hold cargo (one or more objects, items, goods, fragile or breakable articles, live cargo, biological cargo, or the like) during transportation, storage or other activities of the container10. In certain examples, the container10is configured to hold or protect (or both) the cargo (not shown), when the cargo is held within the interior volume12of the container10. In some examples, the container10is part of a system of multiple containers (including other containers10, other similar containers or other different containers) that can be used together, or stacked or arranged together (e.g., in rows or columns, etc.), such as in a modular arrangement.

Container Shell

The outer shell11of the container10may include a bottom wall14and one or multiple side walls16(for example, front, back, left and right side walls) that are connected together, or are formed integrally, to define an interior volume (e.g., volume12) bordered by the side walls16and bottom wall14. In the illustrated examples, the side walls16extend upward from a perimeter of the bottom wall14, to surround and form the open interior volume12of the container10.

In certain examples, the container10is configured to contain and protect cargo (not shown), when the cargo is held within the interior volume12of the container10. The outer shell11(including the bottom wall14and side wall(s)16) of the container10may be formed of a suitably rigid material that holds its shape and resists impacts up to a definable magnitude of force. For example, the outer shell11(including the bottom wall14and side wall(s)16) may be made of one or more (or any combination) of plastic or other polymer, metal, wood, composite material, or the like. The outer shell11(including the bottom wall14and side wall(s)16) may be made by any suitable manufacturing method or methods including, but not limited to injection molding, rotational molding (roto-molding), blow molding, other molding methods, cutting or other machining, or the like. In particular examples, the outer shell11is made of a high strength resin polymer material that can be readily molded into a desired shape.

The outer shell11in the examples shown in the drawings has a generally rectangular, cube shape. However, in other examples, the outer shell11may have any other suitable shape or configuration including, but not limited to other square or other polygonal cube or cuboid shapes, rounded or spheroid or semi-spheroid shapes, or the like. In some examples, the bottom wall14and/or side walls16can be irregular shapes (e.g., a shape including both curved and straight walls, etc.). In some examples, the shape of the outer shell11is configured to correspond to the shape of one or more objects to be held within the container10. In some examples, the shape of the outer shell11is configured for enhancing the ability of the container10to be stacked or arranged together (e.g., in rows or columns, etc.) with other containers10, such as in a modular arrangement.

In some examples, the outer shell11may include a lid or top wall18located opposite the bottom wall14and coupled to the side wall(s)16. In some examples, the lid or top wall18is selectively moveable or removable (relative to the side walls16) to selectively open or close the interior volume12of the container shell11. The lid or top wall18may have a shape and configuration suitable for covering, partially covering, or sealing the open end of the container10, opposite the bottom wall14end of the container10. In certain examples, the lid or top wall18may be made of the same or similar material and methods as described above with regard to the bottom wall14and side wall(s)16of the outer shell11.

In some embodiments, the container10includes one or more hinges coupled to one of the side walls16and the lid or top wall18. The hinges are configured to facilitate selective pivoting of the lid or top wall18relative to the side walls16between a closed configuration and an open configuration. The closed configuration being when the lid or top wall18is in a closed state to isolate or partially isolate the interior volume12from the ambient environment outside of the shell11. The open configuration being when the lid or top wall18is in an open state such that the interior volume12is open to the ambient environment. In other embodiments, the lid or top wall18is coupled to the side walls16via fasteners (e.g., screws, nails, rivets, etc.) or adhesive (e.g., glue, tape, etc.). In certain examples, the outer shell11and (or) the side walls16may include one or more latches or locks to selectively latch or lock the lid or top wall18to the side walls16and secure the lid or top wall18to the side walls16, and to selectively unlatch or lock the lid or top wall18from the side walls16and allow the lid or top wall18to be pivoted, moved or removed to open the container shell11and allow access to the interior volume12.

In some embodiments, one or more (or all) of the bottom wall14, the top wall18, the side wall(s)16or the lid18have multiple wall panels (in a double-walled or other multiple-walled configuration) having an outer wall panel, an inner wall panel and a cavity20between the outer and inner wall panels. In some examples, the cavity20may be empty or sealed and evacuated (vacuum), for thermal insulation. In some examples, a thermal insulating material or a cushioning material (such as, but not limited to, foam, plastic, polystyrene, cellulose, mineral wool, fiberglass, natural fibers, etc.) is located in the cavity20to provide further thermal insulation or to provide further cushioning for the cargo stored within the container10. In some embodiments, one or more (or all) of the bottom wall14, the top wall18, the side wall(s)16or the lid18have one or more openings, valves or other structure that allows passage of air or equalization or adjustment of pressure between the interior volume12of the container10and the exterior environment of the container10, when the lid18is in a closed state.

In particular examples, the container10includes one or more (or a plurality of) interface regions22located on, or formed on the bottom wall14. Examples of interface regions22on a bottom wall14are described with reference toFIGS.3,4,5,6and7. In some examples, the interface regions22are molded portions of the bottom wall14, formed during a process of molding the bottom wall14or the container shell11. Alternatively, the interface regions may be formed or partially formed by stamping, machining or other manufacturing processes. In other examples, the interface region(s)22may be formed on a panel or other structure (not shown) placed on the bottom wall14or otherwise held within the container shell11.

Each interface region22is configured to couple to a respective flexible vibration isolator member100. The interface regions22may have any suitable configuration or shape and, in particular examples, are configured to hold and retain the flexible vibration isolator members100in a fixed position, while allowing the flexible vibration isolator members100to flex and compress along multiple directions (along multiple axes).

FIGS.3and4show top-down views of two respective examples of an interface region22(located on the upward-facing surface of the bottom wall14).FIGS.5and6show a cut-away, section view and an exploded cut-away, section view of the example interface region22ofFIG.3, with a vibration isolator member100and a deck50secured thereto.FIG.7shows an exploded cut-away, section view of the example interface region22ofFIG.4, with a vibration isolator member100and a deck50secured thereto. In particular examples, the bottom wall14may include a single interface region22. In other examples, the bottom wall14includes a plurality of interface regions22arranged in a pattern including, but not limited to a pattern as described herein with regard toFIGS.16-20.

In particular examples, the bottom wall14is provided with one or more (or a pattern) of interface regions22at pre-defined locations, for mounting one or more vibration isolator members100to the bottom wall14at the one or more (or pattern) of locations. In particular examples, the one or more (or pattern) of locations is configured for providing a desired or maximum support capability, vibration isolation and stability (when supporting a deck or platform50). In some examples, the bottom wall14of the outer shell11is provided with a plurality of interface regions22arranged in multiple selectable patterns or multiple selectable locations, to allow one or more vibration isolator members100to be mounted to the bottom wall14at one or more selectable patterns or locations, such that the same outer shell11may be configured for any one of multiple different cargo or decks, or for selecting a desired container support capability, vibration isolation or stability for a given cargo or deck.

In certain examples, each interface region22includes a protrusion24extending upward from other portions of an inside surface26of the bottom wall14. As described herein, each protrusion24provides a mounting surface25on which a respective vibration isolator member100may be mounted. In some embodiments, the protrusion24(and mounting surface25) has a defined peripheral shape (e.g., a circle, a square, a triangle, etc.). In the example inFIGS.3,5and6, the protrusion24(and mounting surface25) has a square shape. In the example inFIGS.4and7, the protrusion24(and mounting surface25) has a round shape. In certain embodiments, the protrusion24(or mounting surface25) has a non-symmetrical or irregular peripheral shape (e.g., a circle with a notch, a square with a rounded side, etc.).

In some examples, the mounting surface25is provided along (or defines) a horizontal plane that is substantially parallel with the horizontal major plane (the rest of the upward-facing surface) of the bottom wall14. In other examples, the mounting surface25of one or more (or each) of the interface regions22are provided in (or define) a plane that is at an oblique angle relative to the major plane of the bottom wall14. The angle of the mounting surface25can determine the angle of a major axis A1of the vibration isolator member100, when supported on the mounting surface. In certain examples, the protrusion24(or mounting surface25) may have a shape or configuration that provides one or more functions or operations, including: (a) supporting or retaining a flexible vibration isolator member100while allowing the flexible vibration isolator member100to flex and compress along multiple axes; (b) holding or directing the flexible vibration isolator member100in a predetermined orientation relative to the bottom wall14; (c) forming a recess or contour on the outer bottom surface of the bottom wall14to facilitate stacking or arranging the container10with other containers or structures; (d) facilitating manufacturing or assembly of the container10; or (e) any combination thereof.

The interface region22can include an opening or a recess28within the protrusion24. The opening or recess28can have the same peripheral shape or a different peripheral shape than the protrusion24. The opening or recess28forms a receptacle for receiving a downward extending hub of a vibration isolator member100, as described herein. In some examples, the opening or recess28is provided in a central portion of the protrusion24(or of the mounting surface25), such that the mounting surface25defines a full or partial annular or ring shape that surrounds (or partially surrounds) the opening or recess28. The annular or partially annular mounting surface25can provide mounting support and multiple locations for fasteners around (or partially around) the opening or recess28. In particular examples, the vibration isolator member100is mounted onto the mounting surface25such that orientation of the main axis A1of the isolator member100is defined, at least in part, by the orientation of the plane of the mounting surface25. In particular examples, the mounting surface25has a size and peripheral shape that is smaller than the size and peripheral shape of the vibration isolator member100(at its maximum width or diameter), to avoid or reduce interference with the ability of the vibration isolator member100to flex and compress along multiple directions (or axes).

In particular examples, the protrusion24of each interface region22forms a recess or contour (e.g., having a reverse shape of the protrusion24) on the outer, bottom surface of the bottom wall14. In certain examples, a plurality of interface regions22forms a plurality or pattern of recesses or contours27that facilitate stacking or arranging the container10with other containers or structure. In such examples, the container lid18of a first container10may include one or more (or a plurality of) protrusions that fit within the recesses or contour on the bottom surface26of a second container (similar to the container10), when the second container is stacked on top of the first container. Similarly, the first container10may be stacked on top of yet another container having a similar lid configuration. When stacked, the recesses or contours of the container10receive protrusions on the lid of another container, to help retainer the containers in a stacked orientation, without moving or slipping laterally relative to each other.

In certain examples, the interface region22includes one or more fastener apertures30(e.g., holes, slots, openings, etc.) on the mounting surface25or other portion of the protrusion24, or in the recess28. In the example inFIGS.3,4,5,6and7each protrusion24includes four fastener apertures30(where three are shown in the cross-section view ofFIGS.5,6and7), at spaced locations around the perimeter of the recess28. In other examples, the protrusion24may include more or fewer than four fastener apertures30(for associated fasteners), spaced around the perimeter of the recess28. Each fastener aperture30is configured to receive a fastener40(such as, but not limited to a bolt, a screw, a bracket, a clip, or the like) configured to fixedly couple the flexible vibration isolator member100to the mounting surface25(and, thus, to the bottom wall14of the outer shell11).

In some examples, each fastener40includes a head and a threaded shaft, and is associated with one or more spacers42(such as, but not limited to one or more washers). In such examples, the threaded shaft of the fastener40may be configured to extend through a fastener aperture and make threaded engagement with a threaded aperture or threaded nut in or on a vibration isolator member100, while the head of the fastener40and the one or more spacers42are located on the exterior surface side of the bottom wall14. In some examples, the recess or contour27on the outer surface side of the bottom wall14has a width that is larger than a diameters of the head of the fastener40and the spacer42, such that the head of the fastener40and the spacer42are received within the recess, when the threaded shaft of the fastener40is threaded into the threaded aperture or nut of the vibration isolator member100. In certain examples, the recess27has an annular shape, corresponding to an annular shape of the mounting surface25. In other examples, other suitable fasteners and fastening configurations may be employed for securing a vibration isolator member at one or more (or multiple) locations around an annular mounting surface25of a protrusion24. In yet other examples, other suitable fasteners and fastening configurations may be employed, for securing a vibration isolator member100to an interface region22on the bottom wall14of the outer shell11, without protrusions24.

In particular examples, the container10(or the vibration isolator system) includes a deck or platform50(hereinafter referred to as the deck50) such as, but not limited to a panel, rack, shelf, box, basket, or other support structure capable of supporting cargo. In certain examples, the deck50is located or configured to be located within the interior volume12of the outer shell11of the container10. In other examples, a vibration isolator system includes a deck50, outside of (or without) an outer shell11. The deck50has a surface or region52(such as, but not limited to, an upper surface) for receiving and supporting cargo. The deck50has a surface54(such as, but not limited to, a lower surface) that faces opposite to the cargo-supporting surface or region52.

In some examples, the cargo-supporting surface or region52includes a generally flat surface on which cargo may be placed. In other examples, the surface or region52has a feature, contour or shape for retaining a specific type of cargo (including, but not limited to one or more recessed regions, retaining walls, or shaped or rounded contours for retaining correspondingly shaped, rounded or spherical cargo, etc.). In further examples, the surface or region52of the deck50may include or operate with one or more cargo retaining mechanisms for holding cargo onto the surface or region52, such as, but not limited to one or more brackets, clips, straps, bands, magnets, Velcro, adhesive, or the like.

In some examples, the deck50may have an outer perimeter size or shape that is similar to or corresponds to an inner perimeter size and shape of the side wall(s)16of the outer shell11of the container10, to maximize the cargo-retaining area of the surface or region52of the deck. In other examples, the deck50may have an outer perimeter size or shape that is smaller than the inner perimeter size and shape of the side wall(s)16of the container10, to provide a gap between the outer perimeter of the deck50and the inner surface of the side wall(s)16, to allow or enhance lateral movement of the deck50relative to the inner surface of the side wall(s)16. In particular examples, the deck50may have an outer perimeter size that provides a gap of several millimeters, centimeters, or a percentage of a width of the deck50(e.g., 1-20 mm, 0.5-5% of the width, or more, etc.) between the outer perimeter of the deck50and the inner surface of the side wall(s)16.

In some examples, the deck50includes a panel or other support structure having a suitable structural strength to hold and support cargo (cargo intended to be held within the container10). The deck50may be made of any suitable material or combination of materials including, but not limited to plastic, metal, wood, composite material, or the like. The deck50may have any suitable structural configuration including, but not limited to a solid panel or solid wall structures, for example, for high strength, durability, uniform load bearing capabilities or other functions or advantages. The deck50may have other configurations (including, but not limited to open framework configurations, cavities, honeycomb structure, mesh structure, or the like), for example, for strength, durability, weight reduction, or other functions or advantages.

In some examples, the deck50can include one or more walls (not shown) extending upward from the surface52, to help secure cargo to the deck50or minimize movement of the cargo relative to the deck50. In certain examples, the walls or the deck50(or both) include one or more cargo retaining features (e.g., protrusions, recesses, brackets, clips, straps, bands, magnets, Velcro, adhesive, or the like), configured to retain or couple to one or more corresponding feature on the cargo, to secure the cargo to the deck50.

In particular examples, the deck50includes one or more (or a plurality of) interface apertures58(e.g., openings, holes, slots, etc.), each for receiving an upward extending hub of a vibration isolator member100, or a fastener41(or both), as described herein. In particular examples, the deck50is provided with one or more (or a pattern) of interface apertures58at pre-defined locations of the deck50, for mounting one or more vibration isolator members100to the deck50at one or more (or pattern) of locations of the deck50. In particular examples, the one or more (or pattern) of locations is configured for providing a desired or maximum support capability and stability for the deck50(and cargo supported on the deck50). In some examples, the deck50is provided with a plurality of interface apertures58arranged in multiple selectable patterns or multiple selectable locations, to allow one or more vibration isolator members100to be mounted to the deck50at one or more selectable patterns or locations, such that the same deck50may be configured for any one of multiple different cargo or for a selected or desired support capability, vibration isolation or stability. In some examples, each interface apertures58also receives a spacer64. In certain examples, each interface aperture58extends through the deck50, and may include an opening on the upper surface52and an opening on the lower surface54of the deck50.

The fastener41may be similar to the fastener40discussed herein, or may be a different, suitable fastener. In certain examples, each fastener41includes a head and a threaded shaft, where the threaded shaft is configured to extend through an interface aperture58(or through a spacer64and an interface aperture58) and make threaded engagement with a threaded aperture or nut in or on a vibration isolator member100, while the head of the fastener41(and a head portion of the spacer64) is located on the surface52side of the deck50.

In certain examples, each interface aperture58includes a first region60, extending upward (e.g., towards the upper surface52) from the lower surface54. The first region60can be configured to receive an upward extending hub of the vibration isolator member100. Each interface aperture58further include a second region62extending downward (e.g., towards the lower surface54) from the upper surface52of the deck50. The second region62can be configured to receive the shaft portion of the fastener41(or the shaft portion of the fastener and a portion of the spacer64). The spacer64is configured to reduce stresses and forces exerted on deck50by the fastener41. The spacer64may be made of any suitable high strength plastic, metal, composite material, or the like. In certain examples that include spacers64, the selection of materials and configurations for forming the deck50can be increased, as the spacers64may protect the deck50from damage.

Vibration Isolator Member

Referring toFIGS.1-20, the container10(or the vibration isolator system) can include one or more (or a plurality of) flexible vibration isolator members100. The flexible vibration isolator member(s)100may be positioned within the interior volume12of the container10and may be coupled to the deck50or to the outer shell11of the container10(or both). In particular examples, the flexible vibration isolator member(s)100are positioned below the deck50(and below cargo held on the deck50), to support and hold up the deck50(and cargo) from below. However, in various examples, the flexible vibration isolator member(s)100may be arranged in other locations within the outer shell11of the container10, for example, above, next to, or surrounding the deck50and cargo. In yet other examples, a vibration isolator system includes one or more (or a plurality) of the flexible vibration isolator member(s)100arranged to support a deck50(or other structure) outside of (or without) an outer shell11of a container10.

Each flexible vibration isolator member100is configured to deform (e.g., compress, expand) in response to pressure or force, to dampen the transmission of force to the deck50from the outer shell11of the container10. In certain examples, the flexible vibration isolator members100are configured and arranged in the container10, to act as a cushion or dampening structure, to reduce the transmission to the deck50(and cargo supported by the deck50) of vibrations, impact forces or other physical shocks received by the outer shell11of the container10(e.g., due to the container10being dropped, bumped, hit, vibrated, shifted, etc.).

Each flexible vibration isolator member100includes a hollow body102made of a resilient, flexible material and configuration. The hollow body102may be made of any suitable material that has sufficient strength, durability, resilience, and flexibility, such as, but not limited to polyethylene, polypropylene, or other suitable plastic or polymer material. In particular examples, the hollow body102is made of a material that is sufficiently flexible to compress when a sufficient compression force is applied to the hollow body102, and has sufficient resilience to automatically return to its pre-compressed state after a compression force has been removed (self-returning). In particular examples, the hollow body102has one or more openings for venting air out of an interior cavity104of the hollow body102as the hollow body102is being compressed, and for venting air into the interior cavity104as the hollow body102decompresses and returns to a pre-compressed state. In some examples, the vent openings may include openings108and112or one or more other openings (not shown) through a wall106of the hollow body102.

The hollow body102may be made by any suitable manufacturing method including, but not limited to a blow molding method. In other examples, the hollow body102may be made with other suitable molding methods, such as, but not limited to injection molding, rotational molding (roto-molding), or other molding methods, or by machining, extrusion, or the like. In certain examples, the hollow body102can be made in various colors. In some examples, the color of the hollow body102may be selected to represent, or based on a characteristic of the hollow body102, such as, but not limited to, a relative stiffness or flexibility of the hollow body102, a durability or strength of the hollow body102, a supportable weight of the hollow body102, a use period or date of the hollow body102, a type of container or context of use of the hollow body102, or a combination thereof.

In particular examples as shown inFIG.8, the hollow body102has a generally rounded, disc shape with protruding central hubs110and111. The disc-shaped hollow body102may have a generally flat upper side with an upward protruding central hub110, a generally flat lower side with a downward protruding central hub111, and a generally rounded peripheral side. The generally round disc-shaped hollow body102has an outer diameter D (corresponding to the greatest or maximum diameter portion of the hollow body102), and a height dimension H (excluding the height hubs110and111).

The generally round disc shape of the hollow body102defines a main axis A1along which the hubs110and111extend. The hollow, disc-shape of the body102can enhance the ability of the body102to flex or compress along multiple different directions (axes), and can reduce restrictions on the direction of flexibility of compression. For example, a disc-shaped body102may be configured to be flex or compress in any of the multiple directions shown inFIG.8, where the arrows A1-ANrepresent any number of multiple directions (or axes) along which the hollow body102may compress or flex. In particular examples, the axes A2-ANare at any oblique angle, relative to the axis A1. Accordingly, a force or shock directed along any of the multiple axes or directions A1-ANcan result in a compression or flexing of the hollow body102along that direction or axis. In examples having a generally round disc shape of the hollow body102the directions or axes A1-ANalong which the hollow body102may compress or flex can be around the entire circumference of the hollow body102, allowing the hollow body102to compress and flex in response to shocks forces in many different directions.

In other embodiments, the hollow body102can have other suitable shapes, including, but not limited to a rectangular, toroidal, or triangular latitudinal cross-sectional shape, etc. The latitudinal cross-sectional shape of the body102can define a stiffness (e.g., radial, axial, etc.) of the deforming member100in one or more lateral directions. In some examples, a container10may include a plurality of flexible vibration isolator members100having a plurality of different shapes or configurations, at respectively different locations within the interior volume12of the container10, to provide a plurality of support points of differing stiffness or flexibility.

The interior cavity104of the hollow body102defines an open interior volume, and the outer wall106has a defined wall thickness dimension. In particular examples, the hollow body102has no internal structural or walls, within the outer wall106. The open interior cavity104(with no internal walls or obstructions) can enhance the ability of the hollow body102to compress or flex in any of multiple different directions, without obstruction. However, in other examples, the hollow body102may have a toroidal or other configuration that includes an internal wall surrounded by the outer wall106.

The stiffness or flexibility of the hollow body102may be defined, in part, by the material and structure (shape and wall structure) of the hollow body102, by the ratio of the diameter D and height H, and by the wall thickness and interior volume of the hollow body102. In particular examples, the hollow body102is configured to have a selected or desired stiffness and flexibility in one or more defined directions, for example, by selecting one or more (or any suitable combination) of the material and shape of the hollow body102, the thickness of the wall106, the ratio of the diameter D and height H, or other parameters. In certain examples, the hollow body102is configured to have a desired or particular stiffness and flexibility in one or more, or multiple directions (to compress or flex along one or more, or any of the multiple axes or directions A1-ANshown inFIG.8, or other axes). Accordingly, a vibration, physical shock, acceleration, deceleration or other force directed along any of the multiple directions can result in a compression or flex of the hollow body102along that direction or axis, to dampen or inhibit transmission of the force to the deck.

In particular examples, the hubs110and111extend outwardly from the center or main axis A1of the body102. In other examples, one or both of the hubs110and111may extend from an off-centered (or off-axis) location at the top or bottom of the vibration isolator member100. In yet other examples, the vibration isolator member100may be configured without one or both of the hubs110and111.

In certain examples, the downward extending hub111of the vibration isolator member100is configured to interface with (be received within) one or more of the interface regions22of the inside surface26of the bottom wall14of the container10. Similarly, in certain examples, the upward extending hub110is configured to interface with (be received within) one or more of the apertures58of the deck50.

In certain examples, one or both of the hubs110and111may have a shape or size (a latitudinal cross-sectional shape or size) that corresponds to a shape or size (a latitudinal cross-sectional shape or size) of a receptacle (formed by the interface aperture58in the deck50, and by the opening or recess28in the protrusion24of the bottom wall14. In certain examples, that latitudinal cross-sectional shape is a round or circular shape, such that the hub110and111may be received in the receptacle, in any rotational orientation (relative to the main axis A1). In other examples, that latitudinal cross-sectional shape is non-circular and defines one or a plurality of specific rotational orientations at which the hub110or111may be received within the receptacle. In particular examples, the hubs110and111(and associated receptacles) have any suitable latitudinal cross-sectional shape including, but not limited to circular, oval, square, polygonal, complex shaped with curved and straight surfaces, or the like.

In certain examples, the latitudinal cross-sectional shape of the hub110(and of the interface aperture58) is different from the cross-sectional shape of the hub111(and of the opening or recess28), and the shapes are selected such that the hub110would fit into the interface aperture58but would not fit within the opening or recess28. Alternatively, or in addition, the shapes of the hubs110and111are selected such that the hub111would fit into the interface opening or recess28, but would not fit within the interface aperture58. Such examples can help a user to assemble a container110correctly, with the vibration isolator member(s)100facing the proper direction and in a proper orientation.

In certain examples, the hollow body102includes one or more apertures108and112located adjacent or around one or both of the hubs110and111. The apertures108and112may operate as fastening apertures or venting apertures (or both). Each aperture108and112extends through the outer wall106. One or more (or each) of the apertures108and112may be threaded (or include a threaded flange nut114or other threaded nut) to receive a threaded shaft of a fastener40or41, for threaded engagement with the fastener40or41. The flange nut114can provide a threaded receptacle for the fastener40or41and can also reduce forces (e.g., shear, etc.) exerted on or by the fasteners to help protect the body102of the vibration isolator member100. The apertures112are arranged to align with the fastener apertures30on the bottom wall14of the container10, when the hub111is received within the interface opening or recess28in the bottom wall14. Similarly, apertures108may be arranged to align with fastener apertures (not shown) on the deck50, when the hub110is received within the interface aperture58. In other examples, the apertures108(or the apertures112) need not align with fastener apertures or receive fasteners40.

Examples of a flange nut114are shown inFIGS.9-12. The flange nut114includes a cylindrical section115surrounded by a flange116. The cylindrical section115of the flange nut has a threaded interior and is open on one end120to receive a threaded shaft of a fattener40or41, or the like. The flange116includes periphery projections118configured to extend into or through (e.g., pierce, penetrate, etc.) the wall106of the hollow body102to fixedly couple the flange nut114to the hollow body102. In some examples, the flange projections118may have a sharp or pointed tip, to help penetrate the wall106of the hollow body102.

The flange116of the flange nut114is configured to abut against and interface with the hollow body102. The flange nut114example inFIGS.9and10is configured to abut against and interface with an interior surface of the hollow body102. The flange nut114inFIGS.11and12is configured to abut against and interface with an exterior surface of the hollow body102. In the example inFIGS.9and10, the flange projections118extend in the same direction that the cylindrical portion115extends relative to the flange116, to pierce an interior surface of the wall106of the hollow body102while the cylindrical portion115extends into or through the wall106. In the example inFIGS.11and12, the flange projections118extend in the opposite direction that the cylindrical portion115extends relative to the flange116to pierce an exterior surface of the wall106of the hollow body102while the cylindrical portion115extends into or through the wall106. Alternatively, or in addition, the flange nut114can be couple to the wall106by adhesive, or other suitable coupling or fastener mechanisms.

The flange nut114has a flange116with a diameter that is larger than the diameter of the fastener aperture in the hub110or the hub111, or the fastener apertures108and112on the hollow body102. The cylindrical portion115of the flange nut114may extend into the fastener aperture, while the projections118of the flange nut114pierce the wall106of the hollow body102. A flange nut114(according to either of the examples inFIGS.9and11, or other suitable examples) may be secured to the hollow body102at a position on the hub110or the hub111, or adjacent to any of the apertures108and112, to receive and connect with a threaded fastener40or41, as described herein.

A flange nut114according to another example is shown inFIGS.13and14and includes a rivet-like structure that can be installed on the hollow body102, from a location outside of the hollow body102. In certain examples, the flange nut114may include a rivet nut or a slotted rivet nut. In certain non-limiting examples, the flange nut114may include a slotted rivet nut such as, but not limited to the Bollhoff Plusnut® by Rivet Nut USA (a division of Cardinal Components, Inc.), or other suitable slotted rivet nut. In certain non-limiting examples, the flange nut114may include another rivet nut such as, but not limited to the Bollhoff Rivnut®, the Bollhoff Hexnut® or the Bollhoff Rivkle® by Rivet Nut USA (a division of Cardinal Components, Inc.). In certain non-limiting examples, the flange nuts114may include, but are not limited to any nuts having an expandable barrel (of which the Bollhoff Rivnut is an example) or spreadable arms (of which the Bolhoff Plusnut is an example), to form a flange on one or both sides of the wall106of the hollow body. In other examples, the flange nut114may include other suitable rivet nuts or fasteners.

The flange nut114inFIGS.13and14includes a cylindrical portion115having a threaded interior and open end120as discussed herein. The flange nut114inFIGS.13and14has a flange116that does not include projections118, but, instead, is enlarged or flared outward on both surfaces (inner and outer surfaces) of the wall106of the hollow body102, to secure the flange nut114to the hollow body102.

In some embodiments, each vibration isolator member100is fixedly coupled to the deck50and/or the bottom wall inner surface26of the container10via fasteners40and41that secure to flange nuts or other threaded fastener structure, as described herein. In other examples, one or more (or each) vibration isolator member100is fixedly coupled to the deck50and/or the bottom wall inner surface26of the container10via an adhesive. In other embodiments, one or more (or each) vibration isolator member100can include an enhanced friction surfaces (such as, but not limited to a contoured surface, a rubber surface, or the like) to in addition to or in place of one or more (or both) of the hubs110and111and fasteners40and41, to inhibit movement of the vibration isolator member(s)100relative to the bottom wall14or the deck50(or both).

In one example of assembling a container10, an outer shell is formed or obtained, to have an interior volume12of sufficient size and strength to receive and contain a particular cargo (or general cargo). In addition, a deck50is formed or obtained, to have sufficient size and strength to support the cargo. One or more vibration isolator members100are selected (for example, based on stiffness, flexibility, strength or other characteristics) and mounted to the deck50, in a desired arrangement.

In certain examples, each vibration isolator member100may be mounted to the to the inner surface of the bottom wall14of the container10, before the vibration isolator member(s)100are mounted to the deck50. In particular, a downward extending hub111of each vibration isolator member100is aligned with and inserted in a respective one of the openings or recesses28in the protrusion24of the interface region22. Fasteners40are inserted through the fastener apertures30and rotationally coupled to the flange nut114in the apertures112of the vibration isolator member100, to couple the vibration isolator members100to the bottom wall14of the outer shell11. In other examples, the vibration isolator member(s)100may be mounted to the deck50(as described below), and thereafter, the deck and already attached vibration isolator member(s)100may be inserted into the interior volume12of the shell11, and the vibration isolator member(s)100may be mounted to the bottom wall14of the shell11as described above.

To mount each vibration isolator member100to the deck50, the deck50is inserted into the interior volume12of the outer shell11, and the upward extending hub110of the vibration isolator member100is inserted in and received by the interface aperture58in the deck50. A spacer64is or has been disposed within the second region62of the interface aperture58. A fastener41is inserted through the interface aperture58and rotationally coupled to a flange nut114or threaded aperture in the upward extending hub110of the vibration isolator member100.

Cargo may be placed on the surface52of the deck50. Cargo retaining mechanisms may be used to secure the cargo to the deck50. A lid or cover18may be secured over the side walls16to close the interior volume12. Thereafter, the closed container10may be transported, stored or engaged in other activities. In the course of such activities, the container10may encounter physical shocks, including vibrations, bumps, drops, accelerations, decelerations, or the like.

The vibration isolator member(s)100are configured to deform in response to a force, vibration or other physical shock applied to the container10, to dampen the transmission of the force, vibration or other shock to the deck50. The deformation of the vibration isolator member(s)100causes air to vent to and from the interior cavity104, to facilitate contraction and expansion, in reaction to changing forces or loads applied to the vibration isolator member(s)100.

In particular examples, venting apertures in the hollow body102(e.g., apertures108,112or other venting apertures) are configured to facilitate airflow between the environment outside of the hollow body102, and the inner volume of the hollow body102, which can increase or decrease the stiffness of the vibration isolator member100by controlling the speed of expansion or contraction of the vibration isolator member100. One or more venting apertures can be configured to delay airflow into the interior cavity104, to reduce fluctuations of the stiffness of the vibration isolator member100. Also, one or more venting apertures can be configured to more rapidly allow airflow out of the inner cavity than airflow into the interior cavity104, to also reduce fluctuations of the stiffness of the vibration isolator member100. In some embodiments, each of the venting apertures includes a valve, functioning as an interface between the interior cavity104and the environment outside of the hollow body102, where the valves can be configured to restrict/prevent airflow or control air flow into or out of the interior cavity104. In some embodiments, the valves and vent apertures are configured such that, when a load is placed on the vibration isolator member100, air flows from the interior cavity104to the environment outside of the hollow body102at a first flow rate, but when the load is removed, air flows into the interior cavity104from the environment outside of the hollow body102, at a second flow rate that is different from the first flow rate. In some examples, the first flow rate is larger than the second flow rate, facilitating quicker contraction than expansion of the vibration isolator member100.

In some examples, the body102of the vibration isolator member100can include one or more radial slits or cuts105. The radial slits or cuts105can be located around a periphery of the body102, and can be configured to lower a radial stiffness of the deforming member100. The lowered radial stiffness can enhance the ability of the body102to move radially (e.g., twisting, etc.) when a load is applied.

As described herein, the number and location of vibration isolator member(s)100may be selected for providing a desired or maximum support capability, vibration isolation and stability. Referring toFIGS.15-20, various arrangements of one or more vibration isolator members100are shown. However, other embodiments include other suitable arrangements. The arrangements can include any suitable number of the vibration isolator members100. In one embodiment, a single vibration isolator member100is positioned on the bottom wall inner surface26of the container10(e.g., as shown inFIG.15). In another embodiment, four vibration isolator members100are positioned in four respective corners on the bottom wall inner surface26of the container10(e.g., as shown inFIG.16). In yet another embodiment, the vibration isolator members100are arranged in a grid pattern (e.g., having multiple rows and/or columns, as shown inFIGS.17and18). In yet a further embodiment, the deforming members100can be positioned in a circular arrangement or concentric circular arrangement on the bottom wall inner surface26of the container10(e.g., as shown inFIGS.19and20).

In examples described herein, one or more vibration isolator members100may be coupled to the bottom wall14of the outer shell11of the container10. However, in other examples, one or more vibration isolator members100may be coupled to a side wall16or a lid or cover18of the container10, instead of or in addition to the bottom wall14. In some embodiments, one or more vibration isolator members100is coupled (at the upward extending hub110) to a deck50, or to a bottom outer surface of a container10, and is configured to be coupled (at the downward extending hub111) to an anchor surface (such as, but not limited to a surface of a truck-trailer, a floor of a building, a deck of a train car, a deck of a ship, or the like).

In some examples, a container system includes one or more container outer shells11and decks50, and a plurality of hollow bodies102including different hollow bodies of different colors, where one or more hollow bodies102may be selected (based, at least in part, on the color of the hollow bodies) to assemble with one (or each) of the shells11and one of the decks50, to form a container10for a desired context of use. In such examples, each color (for the hollow bodies102) may represent a particular range of values for a characteristic. For example, a first color may represent a first range of weight values (e.g., up to X pounds), a second color may represent a second range of weight values (e.g., above X pounds up to Y pounds), and a third color may present a third range of weight values (e.g., above Y pounds up to Z pounds), where X, Y and Z represent numerical values corresponding to the amount of weight that the vibration isolator member is rated to hold (and where X is greater than Y, and Y is greater than Z). In other examples, the system of hollow bodies may include hollow bodies of other colors to represent other ranges (e.g., two different ranges, or more than 3 different ranges), or may have colors that represent other ranges of characteristics. In other examples, the hollow bodies102may have other suitable markings (as an alternative to color or in addition to color) to represent different characteristics (or range values of a characteristic), where such markings may include but are not limited to numerical or textual messages, patterns, designs or other visually discernable features. With such colored or otherwise marked hollow bodies, a user may select one or more (or a plurality) of hollow bodies102having a first color (representing a first weight range or other characteristic suitable for a desired context of use), mount the selected hollow bodies102to the bottom wall14of a shell11and to a deck50, to form a container10for the desired context of use.
