Definitions
- the present invention relates generally to containers, and particularly to modular container assemblies that are used to store tools and other objects.
- Modular containers are used to store and transport many different objects. Some modular containers are stackable on top of one another for storage or shipment such that there is relatively little movement between the stacked containers. To facilitate stacking, the top surface of one container includes a feature that interlocks with a corresponding feature formed on a bottom surface of another container. Stacking the modular containers allows people handling the containers to optimize the available storage space within a building, as well as the space within a transport vehicle.
- the present invention provides a container assembly for storing and/or transporting goods such as tools.
- the container assembly includes a base, a lid, and a plurality of latching mechanisms positioned around the exterior surface of the base 40 .
- the latches allow a user to secure the lid to the base.
- the lid and the base form an enclosed containment area in which a user can store and/or transport goods, such as tools and other objects.
- the container also includes corner braces and a pair of wheel assemblies that are attached to the lower corners of the base. Each corner is further formed to include an elongated channel.
- the corner braces, the wheel assemblies, and the elongated channel strengthen the base and provide the container with stability.
- the corner braces and the wheel assemblies are attached to the base such that a portion of the corner brace spans the elongated channel. This forms a clearance channel between each molded corner of the base and the corner braces.
- the clearance channels provide clearance behind the corner braces so that a tie down placed across the lid of the container can be connected to the corner braces.
- FIG. 1A is a perspective view of a container assembly according to one embodiment of the present invention.
- FIG. 1B is a perspective view of a container assembly according to one embodiment of the present invention.
- FIG. 2 illustrates a container assembly configured according to one embodiment of the present invention with the lid removed from the base.
- FIG. 3A is a magnified view of a corner brace configured according to one embodiment of the present invention.
- FIG. 3B is a magnified exploded view illustrating the components of the corner brace configured according to one embodiment of the present invention.

- FIG. 5 is a magnified view of a latch assembly for a container configured according to one embodiment of the present invention.
- the present invention provides a container assembly for storing and/or transporting a variety of different objects, such as tools and other equipment.
- the container assembly comprises a two-piece, moldable, stackable case.
- the present invention is not so limited, and that the container assembly need not be moldable or stackable, but rather, can be any type of container used for the storage and/or transportation of a variety of objects.
- FIGS. 1A and 1B illustrate a container assembly 10 configured according to one embodiment of the present invention as seen from the top ( FIG. 1A ) and bottom ( FIG. 1B ) of the container 10 , respectively.
- Container 10 comprises a two-piece molded, stackable container comprising a top section (or lid) 20 and a bottom section (or base) 40 .
- a plurality of latch assemblies 120 are disposed around the perimeter of the container 10 to allow a user to secure the lid 20 to the base 40 .
- the lid 20 and the base 40 form a containment area 12 into which a user may place a variety of different objects for storage and/or transportation.
- Reinforcing corner braces 60 or 90 are disposed at each of the bottom corners of the base 40 . As described in more detail later, the corner braces 60 , 90 impart strength and stability to the container 10 . Additionally, corner braces 90 may include wheel assemblies to facilitate the movement of the container 10 along an underlying support surface.
- one or more optional hinges 14 may be disposed on one side of the container 10 to allow the user to open and close the container 10 without having to lift the lid 20 from the base 40 .
- a plurality of spring-loaded handles 16 may be disposed around the perimeter of the base 40 to assist the user in lifting and transporting the container 10 .
- the handle springs (not shown) will normally bias the handles 16 against the sidewall of the lid 20 .
- the springs would retract the handles 16 against the sidewall of the lid 20 .
- the lid 20 and base 40 may be manufactured together or separately, and may be constructed from any material needed or desired. However, in one embodiment, the lid 20 and base 40 are both manufactured as independent pieces. Particularly, each component is molded as a single piece from a material such as high-density polyethelyne (HDPE), for example. When cured, materials such as HDPE are sufficiently hard with which to provide a crush-resistant “shell” that helps to protect any cargo within the containment area 12 from being stolen or damaged.
- HDPE high-density polyethelyne
- the lid 20 comprises sidewalls 22 that extend downward from a periphery of a top surface 24 .
- the top surface 24 includes a plurality of molded stacking features that allow one container 10 to be stacked with one or more other containers 10 .
- the stacking features comprise a plurality of raised members 26 and a plurality of raised ribs 28 .
- the raised members 26 are generally octagonal in shape and are arranged on the top surface 24 in rows and columns; however, other arrangements are equally suitable.
- the raised ribs 28 extend between each raised member 26 and impart strength to the container 10 .
- the raised members 26 and the raised ribs 28 form a plurality of recesses 30 on the top surface 24 of lid 20 .
- the distribution of the recesses 30 are formed to receive a plurality of complementary stacking features extending from a bottom surface of another container 10 .
- the base 40 also comprises a sidewall 42 that extends from a periphery of a bottom surface 44 .
- the bottom surface 44 is formed to include a plurality of molded, raised stacking members 46 arranged in rows and columns. Both the size and shape the raised stacking members 46 , as well as the arrangement of the raised stacking members 46 over the bottom surface 44 , complements the recesses 30 formed on the top surface 24 of lid 20 . Particularly, the raised stacking members 46 fit into the recesses 30 formed on lid 20 such that they interlock. This prevents containers 10 that are stacked upon one another from sliding or moving relative to one another.
- the geometry of the stacking features on both the lid 20 and base 40 allows for the stacking of containers 10 , oriented in the same direction, or with the containers 10 rotated 90° with respect to one another.
- Both the lid 20 and the base 40 may comprise a plurality of concavities or depressions 32 , 48 integrally formed in the outer surfaces of their respective sidewalls 22 , 42 .
- each depression 32 on the lid 20 generally aligns with a corresponding depression 48 formed in the sidewall 42 of lid 40 .
- the depressions 48 in base 40 provide a recessed area for handles 16 and/or a first part of a latch 120
- the depressions 32 formed in the sidewall 22 of lid 20 provide a recessed area for a corresponding second part of the latch 120 .
- FIG. 2 illustrates the container assembly 10 with the lid 20 uncoupled and removed from base 40 to afford a view inside the assembly 10 .
- the peripheral edge of sidewall 22 is formed to include an integral groove 34 .
- the groove 34 extends around the peripheral edge of the sidewall 22 and is sized to receive a gasket 36 .
- the gasket 36 may be, for example, a rubber gasket formed in a continuous loop.
- the gasket 36 contacts the peripheral edge of the sidewall 42 on base 40 , and forms a substantially air-tight seal. This helps keep moisture and/or other contaminants from entering into the containment area 12 from the ambient environment when the container assembly 10 is closed. Further, depending upon the cargo, the gasket 36 also helps to prevent any materials (e.g., hazardous chemicals, etc.) that may be stored within the containment area 12 from escaping into and polluting the ambient environment.
- the interior of base 40 may be configured to include one or more trays 50 .
- the interior surface of sidewall 42 may be molded to include a plurality of vertically-oriented, integrally-formed, elongated notches 52 .
- Each notch 52 is configured to receive a tab (not shown) extending from the side of tray 50 .
- the notches 52 are generally evenly spaced around the interior surface of the sidewall 42 so that a tray 50 may be positioned in multiple places within the containment area 12 .
- the elongated notches 52 may be formed in any manner known in the art; however, in this embodiment, the notches 52 are formed as trapezoids such that an open end of the notch 52 receiving a tab of tray 50 is slightly wider than an opposing, terminating end of the notch 52 .
- the narrowing width of the notches 52 allows the notches 52 to “lock” the tabs into the notches 52 to help prevent movement of the tray 50 .
- FIGS. 3A-3B illustrate an exemplary reinforcing corner brace 60 according to one embodiment of the present invention.
- Each reinforcing corner brace 60 provides strength and stability to the container 10 .
- a corner brace 60 comprises a unitary, rigid bracket 62 that fixedly attaches to the corner of base 40 using a plurality of mechanical fasteners 74 .

- the corner of the sidewall 42 may include a depression 56 that is sized and shaped to receive the corner brace 60 and prevent it from moving.
- the bracket 62 may be constructed from any material known in the art; however, in one embodiment, the bracket 62 is formed as a unitary piece from a metal or metal alloy such as steel. The bracket 62 is then bent at predetermined angles thereby forming a first end section 64 , a second end section 66 , and an intermediate section 68 that generally conform to the shape of the corner on base 40 . Alternatively, each of the first and second end sections 64 , 66 , and the intermediate section 68 are themselves separate pieces of steel and welded together at desired angles to form the complete bracket 62 . As described in more detail below, an opening 78 is formed in the intermediate section 68 of the bracket 62 , and provides a tie-down and/or lift point for the container 10 .
- the corners of the base 40 include an integrally-formed elongated channel 70 .
- the channel 70 provides the base 40 with additional stability and strength.
- Channel 70 extends into the corner of base 40 and includes a first part 70 a and a second part 70 b .
- the first part 70 a has a generally smooth surface that is a substantially uniform depth from the exterior surface of the sidewall 42 .
- the second part 70 b also has a substantially smooth surface, but is angled to extend towards the exterior surface of sidewall 42 .
- the first and second parts 70 a , 70 b can have any dimensions needed or desired; however, in one embodiment, first part 70 a has a length l 1 that is about the same as the length l cb of the bracket 62 .
- the first and second end sections 64 , 66 contact adjacent portions of the sidewall 22 , and the bottom surface 44 of base 40 .
- the intermediate section 68 is spaced away from the sidewall 42 such that it does not contact the exterior surface of base 40 . More particularly, the intermediate section 68 spans the width of the elongated channel 70 in the corner of base 40 thereby forming a clearance channel 80 between the corner brace 60 and the surface of the first part 70 a .
- the access channel 80 is a space or clearance area behind the brace 60 . With the clearance channel 80 , a user can removably attach one end of a tie-down strap to an elongated opening 78 formed in the intermediate section 68 .
- the user can then stretch the tie-down over the lid 20 of the container 10 (or another container 10 stacked on top), and attach the other end of the tie-down strap to a corresponding opening 78 formed in a corner brace 60 or 90 disposed on an opposite bottom corner of the container 10 .
- FIGS. 4A-4B illustrate another exemplary corner brace 90 configured according to one embodiment of the present invention.

Abstract
A modular container assembly includes a base and a lid configured to be removably coupled to the base to form a containment area. At least one corner brace is attached to the base adjacent a first corner to strengthen the base. An access channel is formed in the first corner of the base and extends beneath the corner brace to provide clearance behind the brace.
Description
- The present invention relates generally to containers, and particularly to modular container assemblies that are used to store tools and other objects.
- Modular containers are used to store and transport many different objects. Some modular containers are stackable on top of one another for storage or shipment such that there is relatively little movement between the stacked containers. To facilitate stacking, the top surface of one container includes a feature that interlocks with a corresponding feature formed on a bottom surface of another container. Stacking the modular containers allows people handling the containers to optimize the available storage space within a building, as well as the space within a transport vehicle.
- Most modular containers are constructed from a hardened polymer or similar material, and are crush-resistant to protect the objects within the container. However, such containers may still be vulnerable at their corners.
- The present invention provides a container assembly for storing and/or transporting goods such as tools. The container assembly includes a base, a lid, and a plurality of latching mechanisms positioned around the exterior surface of the
base 40. The latches allow a user to secure the lid to the base. When coupled together, the lid and the base form an enclosed containment area in which a user can store and/or transport goods, such as tools and other objects. - The container also includes corner braces and a pair of wheel assemblies that are attached to the lower corners of the base. Each corner is further formed to include an elongated channel. The corner braces, the wheel assemblies, and the elongated channel strengthen the base and provide the container with stability.
- The corner braces and the wheel assemblies are attached to the base such that a portion of the corner brace spans the elongated channel. This forms a clearance channel between each molded corner of the base and the corner braces. The clearance channels provide clearance behind the corner braces so that a tie down placed across the lid of the container can be connected to the corner braces.

FIGS. 1A and 1B illustrate acontainer assembly 10 configured according to one embodiment of the present invention as seen from the top (FIG. 1A ) and bottom (FIG. 1B ) of thecontainer 10, respectively.Container 10 comprises a two-piece molded, stackable container comprising a top section (or lid) 20 and a bottom section (or base) 40. A plurality oflatch assemblies 120 are disposed around the perimeter of thecontainer 10 to allow a user to secure thelid 20 to thebase 40. When coupled, thelid 20 and thebase 40 form acontainment area 12 into which a user may place a variety of different objects for storage and/or transportation. Reinforcingcorner braces base 40. As described in more detail later, thecorner braces container 10. Additionally,corner braces 90 may include wheel assemblies to facilitate the movement of thecontainer 10 along an underlying support surface. - In some embodiments, one or more
optional hinges 14 may be disposed on one side of thecontainer 10 to allow the user to open and close thecontainer 10 without having to lift thelid 20 from thebase 40. In addition, a plurality of spring-loadedhandles 16 may be disposed around the perimeter of thebase 40 to assist the user in lifting and transporting thecontainer 10. As is seen inFIGS. 1A-1B , the handle springs (not shown) will normally bias thehandles 16 against the sidewall of thelid 20. Thus, after carrying the container by thehandles 16, the springs would retract thehandles 16 against the sidewall of thelid 20. - The
lid 20 andbase 40 may be manufactured together or separately, and may be constructed from any material needed or desired. However, in one embodiment, thelid 20 andbase 40 are both manufactured as independent pieces. Particularly, each component is molded as a single piece from a material such as high-density polyethelyne (HDPE), for example. When cured, materials such as HDPE are sufficiently hard with which to provide a crush-resistant “shell” that helps to protect any cargo within thecontainment area 12 from being stolen or damaged. - The
lid 20 comprisessidewalls 22 that extend downward from a periphery of atop surface 24. Thetop surface 24 includes a plurality of molded stacking features that allow onecontainer 10 to be stacked with one or moreother containers 10. In this embodiment, the stacking features comprise a plurality of raisedmembers 26 and a plurality of raisedribs 28. The raisedmembers 26 are generally octagonal in shape and are arranged on thetop surface 24 in rows and columns; however, other arrangements are equally suitable. The raisedribs 28 extend between each raisedmember 26 and impart strength to thecontainer 10. Together, the raisedmembers 26 and the raisedribs 28 form a plurality ofrecesses 30 on thetop surface 24 oflid 20. As seen in more detail below, the distribution of therecesses 30, as well as their size and shape, are formed to receive a plurality of complementary stacking features extending from a bottom surface of anothercontainer 10. - The
base 40 also comprises asidewall 42 that extends from a periphery of abottom surface 44. Thebottom surface 44 is formed to include a plurality of molded, raised stackingmembers 46 arranged in rows and columns. Both the size and shape the raised stackingmembers 46, as well as the arrangement of the raised stackingmembers 46 over thebottom surface 44, complements therecesses 30 formed on thetop surface 24 oflid 20. Particularly, the raised stackingmembers 46 fit into therecesses 30 formed onlid 20 such that they interlock. This preventscontainers 10 that are stacked upon one another from sliding or moving relative to one another. The geometry of the stacking features on both thelid 20 andbase 40 allows for the stacking ofcontainers 10, oriented in the same direction, or with thecontainers 10 rotated 90° with respect to one another. - Both the
lid 20 and the base 40 may comprise a plurality of concavities ordepressions respective sidewalls lid 20 is coupled to thebase 40, eachdepression 32 on thelid 20 generally aligns with a correspondingdepression 48 formed in thesidewall 42 oflid 40. Thedepressions 48 inbase 40 provide a recessed area forhandles 16 and/or a first part of alatch 120, while thedepressions 32 formed in thesidewall 22 oflid 20 provide a recessed area for a corresponding second part of thelatch 120. -
FIG. 2 illustrates thecontainer assembly 10 with thelid 20 uncoupled and removed frombase 40 to afford a view inside theassembly 10. As seen inFIG. 2 , the peripheral edge ofsidewall 22 is formed to include anintegral groove 34. Thegroove 34 extends around the peripheral edge of thesidewall 22 and is sized to receive agasket 36. Thegasket 36 may be, for example, a rubber gasket formed in a continuous loop. When thelid 20 is coupled to thebase 40, thegasket 36 contacts the peripheral edge of thesidewall 42 onbase 40, and forms a substantially air-tight seal. This helps keep moisture and/or other contaminants from entering into thecontainment area 12 from the ambient environment when thecontainer assembly 10 is closed. Further, depending upon the cargo, thegasket 36 also helps to prevent any materials (e.g., hazardous chemicals, etc.) that may be stored within thecontainment area 12 from escaping into and polluting the ambient environment. - As stated previously, tools and/or other objects may be stored and transported within the
containment area 12. There is no restriction on the size or shape of the tools and/or objects, and therefore, the objects may be large and small. To help organize smaller objects within thecontainment area 12, the interior ofbase 40 may be configured to include one ormore trays 50. Specifically, the interior surface ofsidewall 42 may be molded to include a plurality of vertically-oriented, integrally-formed,elongated notches 52. Eachnotch 52 is configured to receive a tab (not shown) extending from the side oftray 50. Thenotches 52 are generally evenly spaced around the interior surface of thesidewall 42 so that atray 50 may be positioned in multiple places within thecontainment area 12. - The
elongated notches 52 may be formed in any manner known in the art; however, in this embodiment, thenotches 52 are formed as trapezoids such that an open end of thenotch 52 receiving a tab oftray 50 is slightly wider than an opposing, terminating end of thenotch 52. The narrowing width of thenotches 52 allows thenotches 52 to “lock” the tabs into thenotches 52 to help prevent movement of thetray 50. -
FIGS. 3A-3B illustrate an exemplary reinforcingcorner brace 60 according to one embodiment of the present invention. Each reinforcingcorner brace 60 provides strength and stability to thecontainer 10. As seen inFIGS. 3A-3B , acorner brace 60 comprises a unitary,rigid bracket 62 that fixedly attaches to the corner ofbase 40 using a plurality ofmechanical fasteners 74. In this embodiment,mechanical fasteners 74 extend throughbeveled holes 72 formed in thebracket 62, and into a corresponding number of threadedreceptacles 76 drilled into in thesidewall 42 andbottom surface 44 ofbase 40. The corner of thesidewall 42 may include adepression 56 that is sized and shaped to receive thecorner brace 60 and prevent it from moving. - The
bracket 62 may be constructed from any material known in the art; however, in one embodiment, thebracket 62 is formed as a unitary piece from a metal or metal alloy such as steel. Thebracket 62 is then bent at predetermined angles thereby forming afirst end section 64, asecond end section 66, and anintermediate section 68 that generally conform to the shape of the corner onbase 40. Alternatively, each of the first andsecond end sections intermediate section 68 are themselves separate pieces of steel and welded together at desired angles to form thecomplete bracket 62. As described in more detail below, anopening 78 is formed in theintermediate section 68 of thebracket 62, and provides a tie-down and/or lift point for thecontainer 10. - The corners of the base 40 include an integrally-formed
elongated channel 70. Thechannel 70 provides the base 40 with additional stability and strength.Channel 70 extends into the corner ofbase 40 and includes afirst part 70 a and asecond part 70 b. Thefirst part 70 a has a generally smooth surface that is a substantially uniform depth from the exterior surface of thesidewall 42. Thesecond part 70 b also has a substantially smooth surface, but is angled to extend towards the exterior surface ofsidewall 42. The first andsecond parts first part 70 a has a length l1 that is about the same as the length lcb of thebracket 62. - When attached to the
base 40, the first andsecond end sections sidewall 22, and thebottom surface 44 ofbase 40. Theintermediate section 68, however, is spaced away from thesidewall 42 such that it does not contact the exterior surface ofbase 40. More particularly, theintermediate section 68 spans the width of theelongated channel 70 in the corner ofbase 40 thereby forming aclearance channel 80 between thecorner brace 60 and the surface of thefirst part 70 a. Theaccess channel 80 is a space or clearance area behind thebrace 60. With theclearance channel 80, a user can removably attach one end of a tie-down strap to anelongated opening 78 formed in theintermediate section 68. The user can then stretch the tie-down over thelid 20 of the container 10 (or anothercontainer 10 stacked on top), and attach the other end of the tie-down strap to acorresponding opening 78 formed in acorner brace container 10. -
FIGS. 4A-4B illustrate anotherexemplary corner brace 90 configured according to one embodiment of the present invention. Eachcorner brace 90 provides strength and stability to thecontainer 10, but also includes a wheel assembly to facilitate moving thecontainer 10 over an underlying surface. As seen inFIGS. 4A-4B , thecorner brace 90 comprises a unitary,rigid bracket 92, awheel housing 96, and awheel 104. The structure of therigid bracket 92 is substantially similar to the structure ofrigid bracket 62, and spans anelongated channel 70 formed in the corner ofbase 40 as previously described. Therefore, aclearance channel 80 is formed between theelongated channel 70 and thebracket 92. As above, theclearance channel 80 provides clearance behind thebracket 92 to allow a user to secure one end of a tie down (not shown) into anelongated opening 78 formed in thebracket 92. - As stated previously, this embodiment of the
bracket 92 includes awheel assembly 90. As such, thebracket 92 is slightly different than that ofbracket 62. Particularly,bracket 92 comprises atab 94 that extends downward from thebracket 92. When assembled,tab 94 abuts to, and aligns with, acorresponding tab 100 formed on thewheel housing 96. Both thetab 94 and thetab 100 include anopening 102 that, as described later in more detail, are aligned to support thewheel 104. - The
wheel housing 96 is also a unitary rigid piece. It is constructed from a metal or metal alloy and has a plurality of terminal edges 98. In one embodiment, thewheel housing 96 is secured to thebracket 92 by welding one or more of theedges 98 to the exterior surface of thebracket 92. As seen in the figures, thewheel housing 96 houses awheel 104 that permits a user to roll thecontainer 10 over a smooth flat surface. Anarched notch 112 is formed into thewheel housing 96 so that thewheel 104 is able to spin freely in thewheel housing 96. - The
wheel 104 includes anaxle 106, andbushings axle 106. Thewheel 104 and/or thebushings second bushings axle 106 and thewheel 104. One of thebushings 108 a is supported within adepressed notch 110 integrally formed into thesidewall 42 ofbase 40. Theother bushing 108 b is supported within the alignedopenings 102 formed in the alignedtabs - As stated above, a plurality of
latch assemblies 120 may be disposed around the periphery of the base 40 to secure thelid 20 to thebase 40. As those skilled in the art will readily appreciate, any latch known in the art will allow a user to secure thelid 20 to thebase 40. For example,FIGS. 1A-1B illustrated someexemplary latches 120 as being conventional rotary draw latches. However, in at least one embodiment, the present invention provides an enhancedrotary draw latch 120 for use oncontainer 10. -
FIG. 5 is a perspective view illustrating one embodiment of therotary draw latch 120 provided in one embodiment of the present invention. Therotary draw latch 120 comprises afirst part 122 secured to sidewall 22 oflid 20, and asecond part 124 secured to sidewall 42 ofbase 40. Rivets or other mechanical fasteners may be used to affix the first andsecond parts rotary draw latch 120 to theirrespective sidewalls - According to one embodiment of the present invention, the
rotary draw latch 120 may include anarm 130 secured to thesecond part 124 ofrotary draw latch 120. Thearm 130 is constructed of a unitary piece of metal or metal alloy, and is formed to include one or more bends and turns as needed or desired. In this embodiment, thearm 130 comprises afirst section 132 that connects to thesecond part 124 ofrotary draw latch 120, and asecond section 136 that extends from thefirst section 132. Aslot 136 is formed in thesecond section 134 of therotary draw latch 120. Theslot 136 is sized and placed on thesecond section 134 to receive acorresponding tab 140 that is attached to and extending outwardly from thesidewall 42 ofbase 40. Thetab 140 includes anopening 142 through which a user can connect a padlock (not shown). Once locked, thearm 130 maintains thesecond part 124 of therotary draw latch 120 in a static position against thesidewall 42 ofbase 40 such that a person cannot turn the latch. This prevents unauthorized users from turning and unlatching therotary draw latch 120 to gain access to thecontainment area 12. - The present invention may, of course, be carried out in other ways than those specifically set forth herein without departing from essential characteristics of the invention. The present embodiments are to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
