Abstract

A kit for making boxes from paper card stock. The kit has a flat plate with a guide rail with a vertical edge projecting above the surface of the plate parallel to one edge of the plate. A scoring groove traverses the plate parallel to the vertical edge of the guide rail. One or more spacing strips, each having a vertical edge, may be placed between the vertical edge of the guide rail and the scoring groove to vary the depth of the box. The overall size or "footprint" of a box made in accordance with the invention is determined by the distance of the scoring groove from the nearest vertical edge and the size of the blank card stock employed. Two identical sized card stocks are used for each box. A slightly wider spacing strip is used to form the top than the spacing strip used to form the bottom of the box. This also makes the depth of the box bottom slightly greater than the box top. The kit includes a scoring plate, two sets of spacing strips and a scoring tool, and is used to fashion boxes in a variety of shapes and sizes. In another embodiment of the kit the scoring plate has guide rails and score lines on both sides, wherein the guide rail on one side is spaced slightly further away from the score line than on the other side to make the box bottom slightly smaller in size than the box top.

Dependent claims

A device for making a box from card stock having a thickness, the box comprising a box bottom having a planar bottom surrounded by respective side walls and a box top having a planar top surrounded by respective side walls, such that the box bottom and box top are sized so that, when assembled, the box top slideably fits together with the box bottom, the device comprising:

(a) a scoring plate having a flat planar top surface dimensioned to accommodate and support a sheet of card stock placed thereon, a top guide rail with a vertical edge affixed therein, and a plurality of top surface parallel and spaced apart elongate scoring grooves formed into the planar top surface, each of the plurality of top surface elongate scoring grooves being parallel to and spaced a uniform distance from the stationary top guide rail vertical edge, wherein the flat planar top is for use in forming the box top, the scoring plate having a flat planar bottom surface, which when inverted, is dimensioned to accommodate and support a sheet of card stock placed thereon, and further comprising a stationary bottom guide rail with a vertical edge affixed thereto, and a plurality of bottom surface parallel and spaced apart elongate scoring grooves formed into the planar bottom surface, each of the plurality of bottom surface parallel and spaced apart elongate scoring grooves being spaced a uniform distance from the stationary bottom guide rail vertical edge, which uniform distance is between two and three times the thickness of the card stock used further away from the bottom guide rail than are the top surface grooves spaced apart from the top guide rail, wherein the flat planar bottom is for use in forming the box bottom;
and
(b) a scoring tool operable for forcing a portion of a sheet of the card stock into at least one of the top surface scoring grooves, wherein the box top as scored by the flat planar top of the scoring plate will have a slightly larger size and slightly less depth than the box bottom scored by the flat planar bottom of the scoring plate to size the box top and box bottom so that when assembled, the box top slideably fits together with the box bottom.

A device for scoring sheets of planar card stock, having a thickness, in order to form a nestable top and a bottom of a box, whereinafter after being scored, the sheets of the scored card stock can be cut with a cutting means, folded along score lines, and affixed together to form a nestable top and bottom of the box, which nestable top and bottom of the box are sized so that when assembled, the box top and box bottom slideably fit together, the device comprising:

(a) a scoring plate having a flat planar top surface dimensioned to accommodate and support a sheet of card stock placed thereon, a guide rail with a vertical edge affixed thereto, and a plurality of parallel and elongate scoring grooves formed into the planar top surface each scoring groove being parallel to and spaced a uniform distance from the guide rail vertical edge wherein the flat planar top surface is for use in forming the box top, the scoring plate having a flat planar bottom surface, which when inverted, is dimensioned to accommodate and support a sheet of card stock placed thereon, a bottom guide rail with a vertical edge affixed to the bottom surface, and a plurality of parallel and spaced apart bottom surface scoring grooves formed into the planar bottom surface, each scoring groove being parallel to and spaced a uniform distance from the bottom guide rail vertical edge, which uniform distance is slightly greater than the uniform distance the scoring grooves on the top surface are spaced from the top guide rail, wherein the flat planar bottom is for use in forming the box bottom;
and
(b) a scoring tool operable for forcing a portion of a sheet of card stock into at least one of the scoring grooves to thereby form score lines in the sheet of card stock, wherein the box top as scored by the flat planar top of the scoring plate will have a slightly larger size and slightly less depth than the box bottom scored by the flat planar bottom of the scoring plate to size the box top and box bottom to be nestable, so that when assembled the box top slideably fits together with the box bottom.
