An apparatus for quickly setting up an octagonal box configuration from the typical planar folded tube form in which the boxes are shipped. The apparatus includes separated frame portions representing the octagonal shape which are mounted for relative movement toward one another to cause the planar box form to open along vertical score lines provided on the box form. Another vertically movable frame includes plurality of fixed and pivotal folding plates which engage closure flaps connected to the box form to cause the flaps to fold inwardly along selected score hinge lines to close an end of the box thereby forming an opened, erected box ready to accept the desired contents.

A box forming apparatus for forming a planar, closed box form into an opened, erected octagonal configuration along predetermined score lines provided on said box comprising, in combination; a) a supporting base; b) a box folding frame mounted on said supporting base for opening a planar enclosed box form along preselected vertical score hinge lines into an open preselected octagonal configuration and including a first box folding frame portion mounted on said supporting base and having a plurality of upstanding wall portions disposed in angular relationship to one another generally conforming to a plurality of contiguous upstanding side wall panels of a preselected octagonal box configuration, a second box folding frame portion having at least two contiguous upstanding wall portions disposed in a fixed angular relationship to one another generally conforming to at least two contiguous upstanding side wall panels of said preselected box configuration, each of said wall portions of said second box folding frame portion disposed in opposing, spaced, relationship generally parallel to one of the wall portions of said first box folding frame portion, said first and second box folding frame portions being mounted for relative movement toward one another to engage a pair of vertically disposed opposing edges corresponding to opposing folded score lines of said closed box form and move said edges toward one another to cause said closed box form to open along a plurality of predetermined parallel score lines provided on said box form; c) a closure flap folding fixture including an open generally rectangular frame conforming generally to the greatest width and length dimensions of the preselected box configuration being formed and movably mounted to said supporting base for reciprocal vertical movement above said box folding frame between a raised position and a lowered box engaging position; d) four vertically extending inwardly inclined folding plates, a respective one fixed to a different side of said rectangular frame and configured to engage a preselected area of an upstanding, opened octagonal box configuration disposed in generally vertical alignment below said rectangular frame to cause inward folding of one of a first set of four preselected box closure flaps along preselected score lines provided on said box closure flaps upon moving said rectangular frame to said lowered position; and e) four vertically disposed folding plates, each being mounted for vertical pivoting movement about a horizontal axis and disposed at a respective corner of said rectangular frame, each of said pivotally mounted folding plates disposed to engage a preselected area of said upstanding, opened octagonal box configuration when said rectangular frame is disposed in its lowered position upon pivoting downwardly to cause inward folding of a respective one of a second set of four different box closure flaps and to continue inward folding of said first set of four closure flaps toward a generally horizontal position.
