Cardboard for packaging boxes

Abstract

This product is a cardboard packaging box that is assembled into a rectangular box shape, as shown in the "Reference Perspective View Showing Assembled State". The product is assembled with the sides shown in the "Reference Plan View" as the inside of the box. In the "Reference Plan View Showing Folding Method", blue lines indicate valley folds and red lines indicate mountain folds. By using these lines and folding in order as shown in "Reference Figures 1-8 Showing Assembly Procedure", a rectangular box shape is formed. Conversely, by unfolding a box containing various items (for example, business cards, chocolates, or handkerchiefs), a heart shape ultimately appears, as shown in the "Reference Figure Showing Use", with the contained items (the items that were in the box) revealed in the center. In the "Reference Figure Showing Use", the contained items are several business cards, but other items may also be used. In the case of business cards, this product can also be used as a business card holder.
