Abstract
Abstract Each tray of a multiple tray display rack is formed from a single blank of kraftboard and has a single thickness bottom wall and a double-thickness side wall extending up from each edge of the bottom wall. An outer layer of each side wall is directly connected to the bottom wall around a bend line, and the inner layer is joined to the outer one around a fold line along the top edge of the side wall. The trays are supported in vertically spaced relation by four rods, each confined in one corner of each tray, inwardly adjacent to a flap that extends from an outer layer of one side wall at the corner and is bent around the corner to be sandwiched between the layers of the other side wall at the corner. Each rod is secured in its corner by the inner layers of the side walls that meet at the corner. Each inner layer has tabs projecting from its lower edge and received in closely fitting slots in the bottom wall whereby the inner layer is secured in flatwise proximity to its outer layer.

Claim 1
Independent Claim
293 words
A display rack comprising a tray formed of one piece of a stiff but foldable material such as kraftboard, having a bottom wall with straight side edges and having a plurality of upright side walls that project up from said side edges and meet one another at corners, and supporting means whereby said tray is held with its bottom wall elevated, said display rack being characterized by: A. said supporting means comprising a plurality of upright rods, one for each of said corners; B. said tray having each of its side walls formed with two flatwise superimposed layers of material, (1) an outer one of said layers being connected to said bottom wall around a bend line along one of said side edges and (2) the inner one of said layers being connected to the outer layer around a fold line along the top edge of the side wall; C. said tray further having, at each of said corners, a flap which extends from the outer layer of one of the pair of side walls at the corner and which is bent around the corner and is flatwise confined between the layers of the other side wall of the pair; D. the rod at each of said corners being confined against lateral displacement relative to the tray by (1) being received in the bend of the flap at the corner, and (2) being retained in said bend by the inner layers of the pair of side walls that meet at the corner, each of which inner layers has a portion extending along an upright end edge thereof that engages the rod; and E. each rod having an upwardly facing abutment which is spaced above its bottom end and which supportingly engages the tray.

A display rack comprising a tray formed of one piece of a stiff but foldable material such as kraftboard, having a bottom wall with straight side edges and having a plurality of upright side walls that project up from said side edges and meet one another at corners, and supporting means whereby said tray is held with its bottom wall elevated, said display rack being characterized by: A. said supporting means comprising a plurality of upright rods, one for each of said corners; B. said tray having each of its side walls formed with two flatwise superimposed layers of material, (1) an outer one of said layers being connected to said bottom wall around a bend line along one of said side edges and (2) the inner one of said layers being connected to the outer layer around a fold line along the top edge of the side wall; C. said tray further having, at each of said corners, a flap which extends from the outer layer of one of the pair of side walls at the corner and which is bent around the corner and is flatwise confined between the layers of the other side wall of the pair; D. the rod at each of said corners being confined against lateral displacement relative to the tray by (1) being received in the bend of the flap at the corner, and (2) being retained in said bend by the inner layers of the pair of side walls that meet at the corner, each of which inner layers has a portion extending along an upright end edge thereof that engages the rod; and E. each rod having an upwardly facing abutment which is spaced above its bottom end and which supportingly engages the tray.
Claim 3
Dependent Claim
70 words
The display rack of claim 1, further characterized by: F. the inner layer of each side wall having at least one tab projecting downwardly from its bottom edge and received in a closely fitting slot in the bottom wall whereby said inner layer is confined in flatwise contiguous relationship to the outer layer and each of the end edge portions of the inner layer is maintained engaged with a rod.
Claim 4
Dependent Claim
49 words
The display rack of claim 1 wherein said abutment on each rod is defined by a laterally extending strut which connects the rod in spaced, parallel relation to another rod and which extends along and beneath the fold line between the inner and outer layers of a side wall.
Claim 5
Dependent Claim
37 words
The display rack of claim 1 wherein said abutment on each rod comprises a short, laterally extending portion of the rod that is between and defined by a pair of opposite right angle bends in the rod.
