Abstract
Abstract A berry box or basket and a method of forming the same from a rectangular blank of foldable stock material which is cut and scored to provide, when set up, a square bottom wall, side wall members slanted upwardly and outwardly therefrom with one pair thereof which are disposed opposite each other reinforced and rigidified by connecting glue flaps which are cut from the material at the corners of the blank and hinged to the vertical edges of the adjoining side wall members and which have top marginal portions folded down and secured to the face of the remainder of the flaps so as to stiffen and reinforce the top edge of the wall, and the top margins of the adjoining side wall members being reinforced by a folded down edge strip while the corners are reinforced by small tab members which are each integrally hinged to the edge reinforcing strip or flap on the adjoining wall member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
297 words
A blank for fabricating an open top container in the form of a berry basket which blank is formed of foldable paperboard or similar sheet material, said blank being cut and scored so as to provide a center bottom wall forming panel and side wall forming panels which extend from the edges of the bottom wall together with reinforcing panels cut from the four corners of the blank which are subdivided to provide along the outer side edges of the blank hinged edge reinforcing strips which edge strips are cut free from edge reinforcing strips formed along the intermediate side marginal portions of the blank, said strips being cut so as to leave at one end thereof integral hinged corner connecting tabs which are adapted to be connected so that when the container is completely formed they span the associated corners of the container, the other ends of said intermediate side edge reinforcing strips being cut so as to provide corner connecting tabs which are adapted for spanning the associated vertical corners of the container and for connection to edge reinforcing strips which are cut in the adjoining corner panels at that end of the blank, said reinforcing panels being scored to provide hinge lines for folding into overlying engagement with the adjoining side wall panel and said blank having strips of adhesive extending along the side margins and in the edge reinforcing strip areas enabling the edge reinforcing strips to be folded down onto adjoining blank areas in a predetermined sequence so that the corner connecting tabs on the edge reinforcing strips are engaged in corner spanning or bridging relation with the side wall forming panels and secured upon folding of the blank to complete the container whereby the corners are reinforced by said connecting tabs.

A blank for fabricating an open top container in the form of a berry basket which blank is formed of foldable paperboard or similar sheet material, said blank being cut and scored so as to provide a center bottom wall forming panel and side wall forming panels which extend from the edges of the bottom wall together with reinforcing panels cut from the four corners of the blank which are subdivided to provide along the outer side edges of the blank hinged edge reinforcing strips which edge strips are cut free from edge reinforcing strips formed along the intermediate side marginal portions of the blank, said strips being cut so as to leave at one end thereof integral hinged corner connecting tabs which are adapted to be connected so that when the container is completely formed they span the associated corners of the container, the other ends of said intermediate side edge reinforcing strips being cut so as to provide corner connecting tabs which are adapted for spanning the associated vertical corners of the container and for connection to edge reinforcing strips which are cut in the adjoining corner panels at that end of the blank, said reinforcing panels being scored to provide hinge lines for folding into overlying engagement with the adjoining side wall panel and said blank having strips of adhesive extending along the side margins and in the edge reinforcing strip areas enabling the edge reinforcing strips to be folded down onto adjoining blank areas in a predetermined sequence so that the corner connecting tabs on the edge reinforcing strips are engaged in corner spanning or bridging relation with the side wall forming panels and secured upon folding of the blank to complete the container whereby the corners are reinforced by said connecting tabs.
Claim 3
Dependent Claim
65 words
A blank for fabricating an open top container as set forth in claim 1 wherein said edge reinforcing strips are defined by hinge forming score lines extending in part parallel with the side edges of the blank and in part diagonally inwardly of said blank side edges and said adhesive strips extend in straight lines parallel with said blank side edges and spaced inwardly thereof.
Claim 4
Dependent Claim
235 words
A container in the form of a berry basket which is formed from a paperboard blank or similar foldable sheet material and which comprises a bottom wall forming panel, side wall forming panels upstanding from the side edges of the bottom wall panel, side wall reinforcing and corner connecting panels hinged to the side edges of oppositely disposed side wall forming panels and secured in overlying relation on the inside faces of the adjoining side wall forming panels which are disposed opposite each other, and relatively narrow top edge reinforcing strip members extending about the top margins of the basket which are integral with the side wall corner connecting panels and the associated side wall forming panels to which said corner connecting and reinforcing panels are hinged, said top edge reinforcing strip members being folded down so as to lie along the top margins of the basket side wall members and being adhesively secured to the top marginal face portions of said side wall corner connecting panels and said side wall forming panels, and top edge corner reinforcing tabs at each corner of the basket each of which is integral with an edge reinforcing strip portion lying along the top margins at one side wall of the basket and which is adhesively secured between the edge reinforcing strip portion lying along the adjoining wall of the basket and the associated top margin of said wall.
Claim 5
Dependent Claim
235 words
A container in the form of a berry basket which is formed from a paperboard blank or similar foldable sheet material and which comprises a bottom wall forming panel, side wall forming panels upstanding from the side edges of the bottom wall panel, side wall reinforcing and corner connecting panels hinged to the side edges of oppositely disposed side wall forming panels and secured in overlying relation on the inside faces of the adjoining side wall forming panels which are disposed opposite each other, and relatively narrow top edge reinforcing strip members extending about the top margins of the basket which are integral with the side wall corner connecting panels and the associated side wall forming panels to which said corner connecting and reinforcing panels are hinged, said top edge reinforcing strip members being folded down so as to lie along the top margins of the basket side wall members and being adhesively secured to the top marginal face portions of said side wall corner connecting panels and said side wall forming panels, and top edge corner reinforcing tabs at each corner of the basket each of which is integral with an edge reinforcing strip portion lying along the top margins at one side wall of the basket and which is adhesively secured between the edge reinforcing strip portion lying along the adjoining wall of the basket and the associated top margin of said wall.
