A bag forming apparatus for forming a flat bottom of a bag includes a base, opposing sidewalls that extend upright relative to the base, and a top that is operably coupled to an upper portion of each of the sidewalls. The top has an intermediate pivot axis between the sidewalls that enables the top to pivot about the pivot axis between a collapsed state and an expanded state. In the collapsed state, the upper portions of the respective sidewalls are closer together and the top extends upright relative to the base to form a tip for insertion into an opening of the bag. In the expanded state, the upper portions of the respective sidewalls are spaced further apart and the top extends horizontally relative to the base to form a platform for forming the flat bottom of the bag.

An envelope liner template having a first panel having a pattern inscribed therein and a second panel. The second panel is positioned below the first template and attached by a fastening mechanism. The fastening mechanism is adapted to secure a decorative sheet in place between the first panel and the second panel when a cutting implement cuts through the pattern and the sheet against the second template panel to form an envelope liner.

A device for punching and scoring a medium includes a punch tool and a grooved score guide. The punch tool has a cutter configured to cut an edge of a sheet of the medium. The positioning edge is disposed on the device and configured to guide an edge of the medium and position the medium with respect to the punch tool. The grooved score guide is formed in the device and configured to match a scoring tool to create a score line in the medium. The arrangement between the punch tool and positioning edge is configured to cut a notch in the edge of the medium at a notch point. The grooved score line is disposed in relationship to the punch tool to create the score line in the medium from the notch point across the medium.

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.

An envelope-outlining device that comprises first and second tracing members, the members being movable relative to each other. Each tracing member has a respective tracing edge, and each tracing edge has a protrusion extending from the tracing edge. A method of using the same is also disclosed.
