- FIG. 1B shows lid 26 attached to container 10 . All the walls 14 , 16 , 18 , and 20 taper outwardly from bottom 12 so one container 10 can be nestled into another container 10 .
- the containers 10 can also be stacked on one another by placing one container 10 on top surface 27 of lid 26 of another container 10 .
- Container 10 can also be stacked in an open container 10 by resting on shoulders 32 .
- Each wall has a plurality of flutes. Flutes are vertically oriented from bottom 12 to top planar surface 22 . Flutes 34 are shown on wall 14 , flutes 36 are on wall 16 . Flutes 34 a and 36 a are on inside side walls 14 a and 16 a respectively. Outside side walls 14 b and 16 b show flutes 34 b and 36 b respectively. Flutes 38 are shown on end wall 18 , and flutes 40 are shown on end wall 20 . Inside flutes 38 a and 40 a are likewise shown on inside end walls 18 a and 20 a respectively. Outside end walls 18 b and 20 b show flutes 38 b and 40 b respectively. Flutes typically are rounded grooves that provide support for walls 14 , 16 , 18 , and 20 .
- Outside walls 14 b , 16 b , 18 b , and 20 b show partially rounded or concave portions 34 b , 36 b , 38 b , and 40 b flutes corresponding to the aforementioned flutes.
- the rounded, grooved portions inside the side and end walls and rounded, concave portions outside the side and end walls are identified as flutes.
- the number of flutes is variable and not intended to be limitative. While being described as a plurality of flutes providing maximum strength to the side and end walls, it is also noted that fewer flutes possibly one flute per side and end wall, may be utilized if sufficient support for the walls that would enable stacking and nesting containers is confirmed.
- the flutes on the side and end walls must match or be aligned.
- the outside flutes 34 b , 36 b , 38 b and 40 b must fit within the inside flutes 34 a , 36 a , 38 a and 40 a for nesting to occur when one container is placed inside a bottom container 10 as seen in FIG. 11 .
- End walls 18 and 20 each have a different number of flutes, typically one end wall with an even number, the opposed end wall an odd number, whereas side walls 14 and 16 have an even number of flutes. Even with an different number of flutes on each end wall, an end wall with a certain number of flutes will be aligned with an end wall with same number of flutes with the container for nesting purposes.
- end wall 18 has four flutes 38 whereas end wall 20 has three flutes 40 .
- the top container is rotated 180 degrees so the flutes on the end walls are misaligned and nesting will not occur.
- the flutes provide support and rigidity to the side walls and end walls.
- Lid 26 is moved into a cooperatively sealing position with container 10 by aligning raised peripheral edge 28 and lip 30 with raised edge 24 on planar top surface 22 on opposed end walls 18 , 20 .
- the C-shaped opening 31 formed from edge 28 and lip 30 forms track 31 a for engaging raised edge 24 of planar top surface 22 of container 10 .
- As lid 26 is moved forward advancing C-shaped track 31 a on raised edge 24 it moves on each end wall to a side wall on container 10 opposed from the side wall where initial contact was made.
- the lid can engage raised edge 24 on the end walls from either side of the container.
- side wall 14 is utilized.
- Locking hasp 42 is placed on each side wall of container 10 on top planar surface 22 and lid 26 .
- Locking hasp 42 a is located on planar top surface 22 on the top of side wall 16
- locking hasp 42 b is located on the planar surface 22 on top of opposed side wall 14 .
- In locking hasps 42 a and 42 b are holes 43 a and 43 b in container 10 , which are aligned with holes 42 c and 42 d , respectively, on lid 26 .
- pin 43 c is placed in holes 43 a , 43 b , 42 a , and 42 b for locking lid 26 to container 10 .
- padlock 44 engages locking hasp 42 through locking hasp 42 a and 42 b and holes 43 a , 43 b , 42 c , and 42 d for securing lid 26 to box 10 .
- Conventional locks function with hasp 42 , but a preferred conventional lock is a padlock 44 , which may be a combination or key lock, as shown in FIG. 1 b .
- locking hasp 42 includes locking hasp 42 a , 42 b , and further includes holes 42 c and 42 d on lid 26 , holes 43 a and 43 b on planar surface 22 , and pin 43 c that is inserted in all the holes for locking lid 26 to box 10 and lock 44 , which may be a conventional padlock securing lid 26 to box 10 through holes 43 a , 43 b , 42 c , and 42 d .
- C-shaped track 31 a not only engages raised edge 22 on top of end walls 18 and 20 , it engages raised edge 22 on the side wall opposed to the side wall receiving the moving lid 26 .
- Lid 26 can be slid on the container from either side. With two locking hasps 42 a and 42 b , lock 44 , and pin 43 c , the lid 26 forms a secure seal on the container. When closed and locked, container 10 is tamper resistant.
- lid 26 Additional strength is added to lid 26 by runners 46 placed on the top surface 27 of the lid. Runners 46 provide additional thickness to the molded polypropylene and assist in the distribution of weight across the top surface 27 of lid 26 . Spaces 48 are areas for placing identifying indicia such as names, numbers codes, etc. Ridges 50 and 52 on top surface of lid 26 provide a defined area for placing stackable containers. Reinforced corners 54 of ridges 50 and 52 stabilize a stacked container on top surface of lid 26 .
- FIG. 2 shows a stacked container 56 on lid 26 of container 10 . Corners 54 of stacked container 56 fit within reinforced corners 54 of ridges 50 and 52 . Lid 26 provides load-bearing support for stacking multiple containers thereon, one atop another.
- FIGS. 3 and 4 are cross-sectional views of the stacked container of FIG. 2 showing c-shaped track 31 a with lip 30 and peripheral edge 28 engaging planar top surface 22 and raised edge 24 for a secure fit.
- FIG. 6 shows container 10 b with the number of flutes being varied on the end walls 18 and 20 and side walls 14 and 16 from those shown in FIG. 5 .
- Containers made in the manner shown in FIG. 6 will function in the same manner as those shown in FIG. 5 .
- Side wall 14 contains three shoulders 32 for supporting a stacked container without a lid and has four flutes 34 .
- Side wall 16 contains four shoulders 32 . Upon removing a stacked and container from planar top surface 22 and rotating is 180°, it will be nestable in container 10 a . End walls 18 and 20 do not have shoulders.
- FIG. 7 shows a container 10 c with at least on flute 34 and one shoulder 32 on side wall 14 and end walls 18 with flute 38 and end wall 20 with flute 40 .
- Side wall 16 has two flutes 36 with two shoulders 32 .
- FIGS. 6 and 7 show embodiments with variable numbers of flutes and shoulders, both of which support a stackable container on shoulders 32 that when rotated 180° will nest in container 10 b or 10 c.
- Underside 60 of lid 26 is shown in FIG. 9 .
- Lip 30 of peripheral edge 28 is shown on three sides of lid 26 .
- C-shaped opening 31 is formed by lip 30 and edge 28 .
- Track 31 a runs inside C-shaped opening 31 .
- Brake 62 is shown on underside 60 , which prevents lid 26 from being pulled off container 10 .
- Brake 62 and the engagement of C-shaped track 31 a to raised edge 22 of planar top surface 24 enable the lid to be slidably moved in the plane in which it is installed a certain distance from its closed position until brake 62 engages the top of a side wall of the container, which stops the movement.
- the location of the placement of brake 62 determines how far lid 26 slidably opens from a closed position.
- the lid must be unlocked and slid back from the side wall from which it was locked. Lid 26 cannot be pulled upwardly from container 10 for removal.
- the foregoing structure provides additional security for the contents in container 10 in that lid 26 cannot be quickly opened by lifting it upward from container 10 and provides a limited space for opening the lid so that items can be added to or removed from container 10 without having lid 26 completely removed from the container.
- Lid 26 may be manipulated to by-pass brake 62 for fully removing the lid.
- FIG. 8 shows bottom 12 with defined areas 12 a for placing identifying indicia such as names, numbers, codes, etc. for convenient viewing.
- Container 10 is stacked within a second container without using a lid as shown in FIG. 10 .
- Shoulders 32 as shown in FIG. 5 support the bottom of a second container in a stacked position 58 , creating additional convenience for the user.
- Shoulders 32 are placed between flutes in end walls 18 and 20 .
- there is one more shoulder in an opposed end wall for providing stackable support for a second container, which is placed on shoulders 32 , not flutes, when stacked.
- end wall 18 has four shoulders 32 and three flutes 38 a
- opposed end wall 20 has four flutes 40 a and three shoulders 32 .
- the flutes are misaligned so that they do not engage corresponding flutes but shoulder 32 instead on the end walls.
- side walls 14 and 16 The same arrangement can be made in side walls 14 and 16 , that is, the number of flutes and shoulders can be mismatched, one side wall with, for example, four flutes and three shoulders and the opposed side wall with three flutes and four shoulders or any suitable number. Both the end walls and side walls may have this arrangement. Without being limitative, the description of the invention is directed to an aspect wherein the opposed end walls are described with odd-numbered flutes and shoulders.
- FIG. 10 shows second container 64 stacked in container 10 where shoulders 32 are not seen.
- Partition 66 may be inserted in flutes 34 a and 36 a of side walls 14 and 16 creating separate compartments in the interior of container 10 .
- Supporting edge 68 is shown on flutes on outside side wall 14 b .
- Edge 68 with a flange engages planar top surface 22 when second container 64 is nested in container 10 as shown in FIG. 11 .
- Outer edge 68 serves as a stop for the nesting. Otherwise, second container 64 enters inside container 10 as shown in FIG. 5 .
- second container 64 is rotated 180° so the flutes in end walls 18 and 20 are aligned. This is the nesting position 35 of the containers.
- flutes 38 and 40 aligned that is, concave portions 34 b , 36 b , 38 b , and 40 b on outside walls 14 b , 16 b , 18 b , and 20 b of the second container 64 are aligned with flutes 34 a , 36 a , 38 a , and 40 on inside walls 14 a , 16 a , 18 a , and 20 a of lower container 10 , nesting will occur. Shoulders 32 in the lower container do not engage the top or nesting container. If rotated 180° from this nesting position, nesting will not occur. Instead, the containers are now in a stackable position 58 without lid 26 for the top container rests on shoulders 32 of the lower container. This is the stacking position 58 without lid 26 . Of course, with lid 26 firmly secured to container 10 , stacking of containers as previously described is encouraged.
- FIGS. 12 and 13 show another embodiment of the present invention.
- Secure storage container 70 has walls of reduced height when compared to container 10 .
- Container 70 is essentially structured in the same manner as container 10 but for the fact that side walls 72 and end walls 74 containing concave portions 76 and 78 and include flange 80 and support edge 82 to add further strength to the side walls.

Abstract
A storage container that is secure and tamper proof is provided by a molded, one-piece container having a bottom and upstanding vertically oriented side and end walls. A separate lid is provided that sealingly engages the container. The container includes flutes on the inside and outside of the walls for adding strength to the walls. The flutes on the outside wall of one container fit with the flutes on the inside wall of another container for nesting purposes. The container can be stacked with another container by being placed on the top surface of the lid. A container can also be stacked in a container without a lid by being supported by shoulders on the inside walls of the container without the lid after rotating the container to be nested so that the flutes on the container to be nested engage the shoulders of the container without the lid.

Container 10 is stacked within a second container without using a lid as shown inFIG. 10 .Shoulders 32 as shown inFIG. 5 support the bottom of a second container in astacked position 58, creating additional convenience for the user.Shoulders 32 are placed between flutes inend walls shoulders 32, not flutes, when stacked. For example, inFIG. 5 ,end wall 18 has fourshoulders 32 and threeflutes 38 a, whileopposed end wall 20 has fourflutes 40 a and threeshoulders 32. For stacking purposes without a lid, the flutes are misaligned so that they do not engage corresponding flutes butshoulder 32 instead on the end walls. The same arrangement can be made inside walls -
FIG. 10 showssecond container 64 stacked incontainer 10 whereshoulders 32 are not seen.Partition 66 may be inserted influtes side walls container 10. - Supporting
edge 68 is shown on flutes onoutside side wall 14 b.Edge 68 with a flange engages planartop surface 22 whensecond container 64 is nested incontainer 10 as shown inFIG. 11 .Outer edge 68 serves as a stop for the nesting. Otherwise,second container 64 enters insidecontainer 10 as shown inFIG. 5 . In order to placesecond container 64 incontainer 10 for nesting,second container 64 is rotated 180° so the flutes inend walls flutes concave portions outside walls second container 64 are aligned withflutes inside walls lower container 10, nesting will occur.Shoulders 32 in the lower container do not engage the top or nesting container. If rotated 180° from this nesting position, nesting will not occur. Instead, the containers are now in astackable position 58 withoutlid 26 for the top container rests onshoulders 32 of the lower container. This is the stackingposition 58 withoutlid 26. Of course, withlid 26 firmly secured tocontainer 10, stacking of containers as previously described is encouraged. -
FIGS. 12 and 13 show another embodiment of the present invention.Secure storage container 70 has walls of reduced height when compared tocontainer 10.Container 70 is essentially structured in the same manner ascontainer 10 but for the fact thatside walls 72 and endwalls 74 containingconcave portions flange 80 andsupport edge 82 to add further strength to the side walls. Moreover,side walls 72 and endwalls 74 have sloping faces 84 and 86, respectively engaging side walls and end walls. Sloping faces 84 and 86 also provide additional strength to the side walls. - In operation,
container 10 is stronger, lighter, more functional, and more secure than other storage containers. Containers of the present invention can be stacked with or withoutlid 26 without crushing the contents ofcontainer 10. Withlid 26 in place,ridges lid 26, a second container can be stacked in an uncovered lower container by engagingshoulders 32 on the inside end walls of the lower container. When empty, container can be nested inside one another by simply rotating the empty container 180° from itsstackable position 58. This rotation allows flutes on the outside end and side walls of the top container to fit within the flukes on the inside side and end walls of the lower container This feature saves valuable space in storage areas.Container 10 has rounded edges and corners where bottom 12 joinsside walls walls top surface 22 andlid 26.Lid 26 engagesend walls track 31 a and is slidably opened on the short side of the container allowing access to more of the contents of the container without removing thelid 26 fully. - The sizes and shapes of the storage containers of the present invention may vary from the shapes showing in the drawings.
