Paper board container with platform style bottom

Claim 2

A merchandising container made of a sheet material blank with a bottom panel of polygonal shape having corners where sides of the polygon meet one another, the blank including side panels connecting with one another along score lines at which the blank is bent at the corners of the polygonal bottom to form a sidewall, the sidewall changing from the polygonal shape of the bottom at its lower end to a shape more nearly approaching a circle at its upper end, the bottom being of one-piece construction with at least one side panel and the side panel folding back on itself to locate the bottom at an elevation above the lower edge of the sidewall to provide a platform bottom for the container, the blank having low panels that extend between the level of the bottom panel and the lower edge of the sidewall around all sides of the polygonal bottom panel, at least some of the low panels being longer than the length of an adjacent side of the polygonal bottom panel so that a low panel extends continuously around every corner of the polygon constituting the perimeter of the bottom panel.

Claim 3

The merchandising container described in claim 1 characterized by the bottom of the container being square and the top edge of the sidewall being substantially parallel, with a plane defined by the bottom where said bottom joins the sidewalls.

Claim 4

The merchandising container described in claim 1 characterized by two sides of the bottom being connected with the sidewall by one-piece paperboard constructions in which a panel from each of the two sides extends downward from the bottom and then folds back on itself and extends upward to form the part of the sidewall on the side of the container above the side of the bottom to which the sidewall connects by said one-piece construction, and the sidewall of the container being secured to the other sides of the bottom by downwardly extending edge portions of the other sides of the bottom bonded to confronting edge portions of the sidewall, at least one of said edge portions being bent back on itself to provide a fold into which the other edge portion extends.

Claim 5

Claim 10

A merchandising container blank constructed of sheet material and including a bottom panel of polygonal shape, a connecting panel extending along at least one side of the bottom panel, said connecting panel extending also beyond the end of said side of the bottom panel, and adapted to be bent downward to produce a platform bottom, said connecting panel being of low height, panels of similar low height along all of the other sides of the bottom panel, a sidewall portion of the blank connected with the side of said connecting panel opposite the connection of the connecting panel with the bottom panel and laterally extending beyond the ends of said connecting panel, the sidewall portion having score lines in its lower part corresponding to angles of the polygonal shape of the bottom panel, but the sidewall portion at its upper part being constructed and arranged to make the upper edge of the sidewall portion form a top edge of the container that more nearly approaches a circle than does the polygon bottom.

Claim 11

A merchandising container blank constructed of sheet material and including a bottom panel of polygonal shape, a connecting panel extending along at least one side of the bottom panel, and adapted to be bend downward to produce a platform bottom, said connecting panel being of low height, panels of similar low height along all of the other sides of the bottom panel, a sidewall portion of the blank connected with the side of said connecting panel opposite the connection of the connecting panel with the bottom panel and laterally extending beyond the ends of said connecting panel, the sidewall portion having score lines in its lower part corresponding to angles of the polygonal shape of the bottom panel, but the sidewall portion at its upper part being constructed and arranged to make the upper edge of the sidewall portion form a top edge of the container that more nearly approaches a circle than does the polygon bottom, and characterized by the sidewall portion beyond the ends of the panel that connect it with the bottom panel having other panels along its bottom edge portion of substantially the same height as the panel that connects it with the bottom panel, said other panels being parts of the connecting panel that extend beyond the end of said side of the bottom panel, score lines along which said other panels fold back at 180* to form folds for receiving some of the panels of similar low height along the other sides of the bottom panel to form a platform construction for the bottom when the blank is set up.

Claim 12

A merchandising container blank constructed of sheet material and including a bottom panel of polygonal shape, a connecting panel extending along at least one side of the bottom panel, and adapted to be bend downward to produce a platform bottom, said connecting panel being of low height, panels of similar low height along all of the other sides of the bottom panel, a sidewall portion of the blank connected with the side of said connecting panel opposite the connection of the connecting panel with the bottom panel and laterally extending beyond the ends of said connecting panel, the sidewall portion having score lines in its lower part corresponding to angles of the polygonal shape of the bottom panel, but the sidewall portion at its upper part being constructed and arranged to make the upper edge of the sidewall portion form a top edge of the container that more nearly approaches a circle than does the polygon bottom, and characterized by the sidewall portion beyond the ends of the panel that connect it with the bottom panel having other panels along its bottom edge portion of substantially the same height as the panel that connects it with the bottom panel, said other panels being parts of the connecting panel that extend beyond the end of said side of the bottom panel, score lines along which said other panels fold back at 180* to form folds for receiving some of the panels of similar low height along the other sides of the bottom panel to form a platform construction for the bottom when the blank is set up.

Claim 13

the merchandising container blank described in claim 9 characterized by the sidewall portion being in two parts, each of which is connected with an opposite side of the bottom panel, the bottom edge portions of the sidewall portions beyond the sides of the bottom to which they are connected converging toward one another as they extend beyond the sides of the bottom to which they are connected.

Claim 15

The merchandising container blank described in claim 10 characterized by the bottom being substantially square, and said panels of similar low height along the sides of the square, between those sides to which the sidewall portions are connected, being relieved at their ends adjacent to said other panels so that the blank can fold freely to form a platform bottom when setting up the blank.
