Expandable adapter for a free-standing bag

A foldable and expandable adapter for a free standing bag comprising:

• a plurality of triangular-shaped connector piece with rectangular tabs on the two sides of the connector piece wherein the rectangular tabs are longer in length than the length of the sides the triangular-shaped connector
• wherein the triangular connector pieces has two sides of the triangle are straight and the third side is curved outward
• a crease along the middle of connector piece and plurality of creases at the junction of the rectangular tabs and the triangular-shaped connector
• wherein when the triangular connector piece is folded upon itself along the crease in the middle, the connector assumes a smaller triangle shape such that the elongated rectangular tabs are now along the hypotenuse of the triangular shaped connector piece
• wherein each rectangular tab has at least one horizontal crease at the junction of the elongated portion of the rectangular tab and the top corners of the triangle such that the elongated tab can be folded over along the horizontal crease to generate a rectangular tab with a hinged smaller tab
• wherein a horizontal crease runs along the length of the curved side of the triangular connector between the two corners of the connector that has the creases that enables folding of the rectangular tabs
• wherein when the folded connectors are connected to the vertical cuts along the top corners of a free standing bag using the rectangular tabs, the connectors create an expandable opening for the bag
• wherein the bag can be a flat sheet of single or double-ply paper with plurality of cuts and creases arranged such that when the folded connectors are connected to vertical cuts made on creases along one side of the bag and the flat sheet of paper with the connectors attached is folded along the creases, it forms a rectangular tubular cavity wherein when the bottom of the cavity is folded along cuts and creases, and glued, it forms a free-standing bag with an expandable opening

A foldable, expandable and reusable adapter for a free standing bag comprising:

• a base unit consisting of a contiguous bottom section with a foldable flap on one end and plurality of creases
• wherein the contiguous bottom section is made of four alternating panels of two different rectangular-sized shapes where each section is separated by a vertical crease such that when each section is folded along the crease and the two free ends are joined using the flap, the base unit becomes a rectangular object
• a base unit consisting of plurality of top section panels extending from the bottom section where the dimension of each upper section panel corresponds to the dimension of the bottom section panel and is separated from the bottom section panel by a crease at the junction of the top and bottom panel
• wherein when the base unit is arranged as a rectangular object, the four top section panels remain free to be folded inwards or outwards along the creases at the junctions
• wherein each top section panel contains pair of vertical cut out regions at each short side of the panel
• wherein two opposing top and bottom section panels have a vertical crease in the middle of the panel such that when the rectangular base unit is folded along the vertical crease, it forms a flat rectangular object
• a plurality of triangular connector pieces where two sides of the triangle are straight and the third side is curved outward
• wherein the connector piece has tabs present on two straight sides of the connector such that when the connector piece tabs are inserted into the cut out regions of the two adjacent top section panels of the base unit, the base unit has a rectangular bottom section and a pyramidal top section
• wherein when the base unit with the connectors is inserted into a free standing bag, the rectangular portion of the base unit is inside the bag and the pyramidal portion is outside the bag such that the bag has an expanded opening
