One embodiment relates to an apparatus configured to create a box having a width and a height. The apparatus comprises a first control slider movably connected to a body. The first control slider is structured to move to a width position that alters the box width. A second control slider movably connected to the body. The second control slider is structured to move to a height position that alters the box height. A third control slider movably connected to the body, the first control slider, and the second control slider. The third control slider is responsive to the width position of the first control slider and the height position of the second control slider. A size value guide movably connected to the third control slider and is responsive to movement of the third control slider. The size value guide indicates a paper needed to create the user desired box.

The present patent application discloses an envelope making plate. The envelope making plate includes a plate body with a marking groove, a reference edge; and a scale line or an indication line corresponding to the type of the envelope. The plate body is divided into a working area and a non-working area by the reference edge. The envelope paper abuts against or aligns with the reference edge. One side of the envelope paper is the working area, and another side is the non-working area. The marking groove is set in the working area of the plate body and intersects with the reference edge or an extension line of the reference edge. The marking groove divides the reference edge or the extension line of the reference edge into an acute angle and an obtuse angle. The scale line or the indication line corresponding to the type of the envelope is set along the reference edge and on the side where the marking groove and the reference edge form the acute angle. A second indication line is set in the non-working area of the plate body and is perpendicular to the marking groove. An extension line or virtual extension line of the second indication line intersects with the marking groove within the working area of the plate body. It is easy to achieve a full utilization of the plate body's area when making the envelope by making the angle between the marking groove and the indication line being as an acute angle. It saves the materials of the plate body.

Containers, and sheets for forming containers, having bottom locking features, and related methods. In some embodiments, two opposing bottom panels of a sheet may be configured to define at least a portion of a bottom wall of a container. One such bottom panel may comprise a locking tab and the other such bottom panel may comprise a locking aperture configured to receive the locking tab. In a finished configuration, the locking tab may extend at least substantially parallel to the bottom panels within the locking aperture, and the locking tab and locking aperture may be spaced apart from the side walls of the container in the finished configuration.

A box configuring tool includes a base having a planar surface, a first stop positioned at a first end of the base, and a second stop positioned at a second end of the base opposing the first end of the base. The tool also includes a pair of spaced-apart walls coupled to the base to define an open-ended chute along the base's planar surface. The open-ended chute is disposed between the first stop and the second stop. The open-ended chute has a tapered-width portion contiguous with a constant-width portion.

A folding aid with registers is aligned with notches in a specially designed carton blank to facilitate the efficient manual construction of cartons with gusseted corners.
