Abstract

For cylindrical fluid containers, a nestable tray including a support floor having a top surface which is generally open across the entire length and width thereof. The top surface has a plurality of support areas for supporting thereon an array of upright cylindrical fluid containers such that the containers are directly adjacent to one another. A wall assembly is secured to and extends generally up from the floor and is dimensioned so that the containers when supported on the floor extend above the top of the wall assembly in a low-depth arrangement. The wall assembly has a substantial lower wall part adjacent the floor and a substantial upper wall part generally above the lower wall part and having an inward surface. The upper wall part is substantially vertical at least along the inward surface. The inward surface is configured to contact on a plurality of spaced points, spaced a distance above the floor top surface, the cylindrical fluid containers on the adjacent support areas and to thereby hold the containers upright. The lower wall part angles upwardly and outwardly such that the tray when empty of the containers can nest relative to a similar empty tray.

Claims

1. A nestable tray for cylindrical fluid containers, said nestable tray comprising:

a support floor having a top surface which is generally open across the entire length and width thereof, said top surface having thereon a plurality of support areas for supporting thereon an array of upright cylindrical fluid containers such that the containers are vertically upright and directly adjacent to one another;

a wall assembly secured to and extending generally up from said floor, said wall assembly being dimensioned so that the containers when supported on said floor extend above the top of said wall assembly in a low-depth arrangement;

wherein said wall assembly has a substantial lower wall part adjacent said floor and a substantial upper wall part generally above said lower wall part and having an inward surface;

wherein said upper wall part is substantially vertical at least along said inward surface;

wherein said inward surface of said upper wall part is configured to contact on a plurality of spaced points, spaced a distance above said floor top surface, the cylindrical side surfaces of at least some of the cylindrical fluid containers on the adjacent said support areas and to thereby hold the containers upright;

wherein said lower wall part angles upwardly and outwardly such that said tray when empty of the containers can nest relative to a similar said empty tray, and

wherein said lower wall part angles relative to said upper wall part;

wherein said upper wall part comprises a rail held above said floor by said lower wall part for preventing the cylindrical containers from tipping during transport, said rail includes said spaced points which contact the sides of the cylindrical containers; and

wherein said lower wall part comprises a plurality of columns interconnecting said upper wall part and said floor, said columns tapering upwardly from said floor to said wall assembly, and said columns having generally vertical exterior nesting slots tapering upwardly in a longitudinal direction and tapering inwardly in a lateral direction, said slots positioned on outwardly disposed surfaces of said columns such that the interior surfaces of the columns of a lower tray will nest within the exterior nesting slots of an upper tray when said trays are in a nested configuration.

2. The nestable tray of claim 1, wherein said floor has an open gridwork construction, said open gridwork constructions comprising circular floor members generally centered at each said support area and strut means for interconnecting said circular floor members, said strut means directly connecting said circular floor members to said wall assembly.

3. The nestable tray of claim 1, wherein at least some of said columns each have three inwardly disposed generally vertical faces wherein all three faces are angled relative to one another.

4. The nestable tray of claim 1, wherein at least some of said columns each have, on outwardly disposed surfaces thereof, a generally vertical nesting slot.

5. The nestable tray of claim 1, wherein said floor has a lower surface configured to lock onto and thereby prevent free sliding of said nestable tray on rimmed tops of a layer of fluid containers therebeneath.

6. A nestable tray and cylindrical fluid container system, said system comprising:

an array of upright cylindrical fluid containers;

a support floor having a top surface which is generally open across the entire length and width thereof, said top surface having thereon a plurality of support areas for supporting thereon said array of upright cylindrical fluid containers such that said containers are directly adjacent to one another; and

a wall assembly secured to and extending generally up from said floor, said wall assembly being dimensioned so that said containers when supported on said floor extend above the top of said wall assembly in a low-depth arrangement;

wherein said wall assembly has a substantial lower wall part adjacent said floor and a substantial upper wall part generally above said lower wall part and having an inward surface;

wherein said upper wall part is substantially vertical at least along said inward surface;

wherein said inward surface of upper wall part is configured to contact on a plurality of spaced points, spaced a distance above said floor top surface, the cylindrical side surfaces of at least one of said cylindrical fluid containers on the adjacent said support areas and to thereby hold said containers upright; and

wherein said lower wall part angles upwardly and outwardly such that said tray when empty of said containers can nest relative to a similar said empty tray;

wherein said lower wall part comprises a plurality of columns tapering upwardly in a longitudinal direction and tapering inwardly in a lateral direction from said floor to said upper wall part and interconnecting said upper wall part and said floor, said lower wall part includes through-open areas between adjacent said columns, said through-open areas being void of tray material, and said columns having longitudinal exterior nesting slots disposed outwardly relative to said containers on said support area, wherein said nesting slots are tapered to correspond to the taper of said columns such that the interior surfaces of the columns of a lower tray will nest within the exterior nesting slots of an upper tray when said trays are in a nested configuration.

7. The nestable tray of claim 6, wherein said upper wall part bows outwardly relative to said cans in upper wall areas between adjacent columns, said contact points of said upper wall part being disposed in said bowed area.

8. The nestable tray of claim 6, wherein said lower wall part angles relative to said upper wall part.
