Abstract
Abstract A cardboard blank which is readily erected into a tray-like base having a closure or top panel. Construction contemplates the folding of a pair of opposite side panels into elevated positions relative to a bottom panel, followed by folding of opposite end panels into interconnected relation with the side panels, and then use of the closure or top panel to lock all panels in place. During folding movement of the panels, stacking tabs are projected out of the bottom panel into depending relation therewith and are insertable into slots of a top panel of a supporting container to minimize any shifting in a stacked arrangement of the containers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
172 words
A cardboard container comprising a tray-like base fabricated from a flat cardboard body delineated into a centrally located bottom panel bounded by four wall panels, each said wall panel being folded along a fold line into an elevated position relative to said bottom panel and including at least one stacking tab formed integral thereon extending beyond said fold line inwardly of said bottom panel movable simultaneously with said wall panel incident to said folding movement thereof into a depending relationship with said bottom panel, said wall panels having cooperating connecting tabs and slots along confronting side edges effective to interconnect with each other so as to maintain said elevated position of said wall panels, and a closure panel for said container having a supported position on said interconnected elevated wall panels closing a top opening of said tray-like base bounded by said wall panels, said closure panel having slots to accommodate said depending stacking tabs of a superposed cardboard container, whereby the containers are interconnected with each other when in stacked relation.
Claim 2
Dependent Claim
172 words
A cardboard container comprising a tray-like base fabricated from a flat cardboard body delineated into a centrally located bottom panel bounded by four wall panels, each said wall panel being folded along a fold line into an elevated position relative to said bottom panel and including at least one stacking tab formed integral thereon extending beyond said fold line inwardly of said bottom panel movable simultaneously with said wall panel incident to said folding movement thereof into a depending relationship with said bottom panel, said wall panels having cooperating connecting tabs and slots along confronting side edges effective to interconnect with each other so as to maintain said elevated position of said wall panels, and a closure panel for said container having a supported position on said interconnected elevated wall panels closing a top opening of said tray-like base bounded by said wall panels, said closure panel having slots to accommodate said depending stacking tabs of a superposed cardboard container, whereby the containers are interconnected with each other when in stacked relation.
Claim 3
Dependent Claim
22 words
A cardboard container as defined in claim 1 wherein said wall panels are angularly oriented in said interconnected relation with each other.
Claim 4
Dependent Claim
51 words
A cardboard container as defined in claim 1 wherein said wall panels are comprised of two opposing end panels and Two opposing side panels, and wherein said side edges of said side panels have said connecting slots therein and said side edges of said end panels have said connecting tabs thereon.
Claim 5
Dependent Claim
35 words
A cardboard container as defined in claim 3 wherein said connecting tabs are adapted to be projected into said connecting slots incident to movement of said end panels into elevated relation adjacent said side panels.
Claim 6
Dependent Claim
29 words
A cardboard container as defined in claim 4 wherein said peripheral edges of said end and side panels and of said closure panel have cooperating connecting tabs and slots.
Claim 7
Dependent Claim
274 words
A cardboard container comprising a tray-like base fabricated from a flat cardboard body delineated into a centrally located bottom panel bounded by two opposing side panels and two opposing end panels, each said side panel having a connecting slot formed in a side edge thereof and folded along a fold line into an elevated position relative to said bottom panel, each said end panel having a connecting tab formed on opposite side edges thereof and folded along a fold line into an elevated position between said elevated side panels such that said connecting tabs thereon are each projected in connecting relation into a cooperating one of said connecting slots on said side panels, said peripheral edges of said end and side panels bounding a top opening of said tray-like base and having spaced slots formed thereabout, at least one stacking tab formed integral on each of said end and side panels and extending beyond said fold line inwardly of said bottom panel and movable simultaneously with said end and side panels incident to said folding movement thereof into a depending relationship with said bottom panel, and a closure panel having a supported position on said interconnected side and end panels within said top opening, said closure panel having laterally extending connecting tabs thereon adapted to be projected in connecting relation through said slots in said peripheral edges of said end and side panels so as to maintain said elevated position of said end and side panels, said closure panel having slots to accommodate said depending stacking tabs of a superposed cardboard container, whereby the containers are interconnected with each other when in stacked relation.
Claim 8
Dependent Claim
274 words
A cardboard container comprising a tray-like base fabricated from a flat cardboard body delineated into a centrally located bottom panel bounded by two opposing side panels and two opposing end panels, each said side panel having a connecting slot formed in a side edge thereof and folded along a fold line into an elevated position relative to said bottom panel, each said end panel having a connecting tab formed on opposite side edges thereof and folded along a fold line into an elevated position between said elevated side panels such that said connecting tabs thereon are each projected in connecting relation into a cooperating one of said connecting slots on said side panels, said peripheral edges of said end and side panels bounding a top opening of said tray-like base and having spaced slots formed thereabout, at least one stacking tab formed integral on each of said end and side panels and extending beyond said fold line inwardly of said bottom panel and movable simultaneously with said end and side panels incident to said folding movement thereof into a depending relationship with said bottom panel, and a closure panel having a supported position on said interconnected side and end panels within said top opening, said closure panel having laterally extending connecting tabs thereon adapted to be projected in connecting relation through said slots in said peripheral edges of said end and side panels so as to maintain said elevated position of said end and side panels, said closure panel having slots to accommodate said depending stacking tabs of a superposed cardboard container, whereby the containers are interconnected with each other when in stacked relation.
