Abstract: The invention relates to the creation of three dimensional objects from elements or blanks produced by inscribing inwardly and outwardly extending circles about a plurality of polygons, such as isoceles triangles, rectangles, or trapezoids of four, six or other even numbered sides through each point where the sides of the polygons intersect. To provide the appropriate arc lengths, the inscribed circles have the same diameter as the length of the side of the polygon where the arcs are to be inscribed. The element is bent or folded along each arc to form the three dimensional object. Multiple elements can be jointed for form complex elements by superimposing individual elements upon a portion of adjacent elements. The objects thus formed can be held together by forces generated by the folded arcs, although an adhesive may optically be used. The elements, three dimensional objects, and methods of making same also form part of this invention.

Abstract: A new bag cassette having a main bottom panel formed by a diagonal panel defined by a pair of spaced parallel fold lines and a pair of side panels is used to protect and position a bag and for squaring a carton. The bag spout is held in a reinforcing panel connected to the main bottom panel by a spacing panel and the bag is protected by the envelope formed by folding the two side panels perpendicular to the diagonal panel. To square a box having a cross section substantially corresponding with the periphery of the main panel, the cassette is inserted into the box with a diagonal panel extending diagonally between the pair of opposed corners of the box and with the side panels in folded enveloping position substantially perpendicular to the diagonal panel. As the cassette is moved down into the box it tends to force the box into squared position. Folding out of the side panels into a position parallel to the diagonal panel completes the squaring and positions the cassette in the bottom of the box.

Abstract: A cross-shaped rigid sheet is creased and folded in rectangular sections. An elongated rectangle is subdivided into four small rectangles: three wall-forming rectangles and one interior-support-forming rectangle. Interconnection by tabs and slots forms a box structure of triangular cross-section. End-forming rectangles are creased to form a triangular end with two triangular tabs. The triangular tabs are inserted in wall slots to close both ends. An interior support wall stretches from an apex of the triangle to the middle of an opposite wall. Aligned hand slots through two exterior walls and the intermediate interior support form a handle means. Alternately an external carrying handle may be attached to the box structure. A rigid support strip with a handle recess may be used for lifting reinforcement. Holes in the triangular tabs make them easier to pull out of the slots. Protrusions from the walls through the triangular tab holes serve as a locking means.
