  • Patent number: 5628450
    Abstract: An octagonal box structure comprises eight upstanding side wall panels and eight closure flaps integrally connected to one another and closing an end of the box structure. The side wall panels include four smaller panels having a width dimension of about 20 to 40 percent of the width dimension of the narrowest pair of the remaining four side wall panels. The closure flaps have a width corresponding to the width of the side wall panel from which they depend. Four of the closure flaps include diagonally extending score hinge lines to permit each of the these closure flaps to fold inwardly in partial overlapping relationship upon itself and the next adjacent closure flap. The diagonal score lines are formed at an angle between about 20 to 25 degrees relative to an extension of the vertical score lines which define the width of each closure flap. Also disclosed is an apparatus for quickly setting up the box from the typical planar folded tube form in which the boxes are shipped.

  • Patent number: 5624368
    Abstract: 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.

  • Patent number: 5533666
    Abstract: An octagonal box structure comprising eight upstanding side wall panels and eight closure flaps integrally connected to one another and to the side wall panels for folding inwardly along a generally horizontal score hinge line to close an end of the box structure. The side wall panels include four smaller panels having a width dimension of about 20 to 40 percent of the width dimension of the narrowest pair of the remaining four side wall panels. The closure flaps have a width corresponding to the width of the side wall panel from which they depend. Four of the closure flaps include diagonally extending score hinge lines to permit each of these closure flaps to fold inwardly in partial overlapping relationship upon itself and the next adjacent closure flap to form a closed end of the box. The diagonal score lines are formed at an angle between about 20 to 25 degrees relative to an extension of the vertical score lines which define the width of each closure flap.
