Abstract
An eight-sided foldable container having a bottom of the glued-automatic variety is disclosed. The container is constructed from a single sheet of foldable material which comprises eight side panels, a plurality of which are provided with bottom panels which extend angularly downwardly from the side panels via fold lines. These bottom panels are folded inwardly at their respective fold lines toward the center of the formed container such that two pairs are bonded together so as to enable the remaining bottom panels to interlock with and be supported by said bonded bottom panels, thereby forming a container bottom capable of supporting substantial weight, as well as being folded to a relatively flat condition. The blanks used for the construction of the container are also disclosed.
Claims9
An eight-sided container comprising at least one sheet of flexible material, said flexible being divided by fold lines into eight-side panels, said fold lines being positioned such that when the terminal ends of said flexible material are secured together, said flexible material forms a tubular wall structure having eight sides;
- a collapsible end structure, comprising a plurality of six flaps hingedly extending from one end of a plurality of the side panels at an angular relationship thereto, a first and second pair of said flaps extending from a first and second pair of side panels which are oppositely deposed from each other when said container is in an erected position, the first flap of said first and second pairs of flaps being fixably attached to the second flap of said first and second pair of flaps, said flaps being adapted to interlock with each other to form a bottom portion of said eight-sided container when said container is opened to an erected position without the need for any additional manipulative steps, wherein said bottom portion is capable of being collapsed to a flat position within said container when said container is in a storage position.
A blank for forming an eight-sided container comprising at least one sheet of flexible material, said blank being divided by a plurality of fold lines into eight-side panels, said fold lines being positioned such that wwhen the terminal ends of the blank are secured together, said flexible material forms a tubular wall structure having eight sides, said blank further comprising a plurality of six flaps which hingedly extend from the end of six of the eight-side panels at an angular relationship thereto, a first and second pair of said flaps extending from a first and second pair of side panels which are oppositely deposed from each other when the container is in an erected position, the first flap of said first and second pairs of flaps being adapted to be fixably attached to the second flap of said first and second pair of flaps when said blank is in an erected position, said fixably attached flaps being adapted to interlock with each other to form a bottom portion of the eight-sided container when the terminal ends of the blank are secured together to form the tubular wall structure having eight sides, wherein said bottom portion so formed is capable of being collapsed to a flat position within said container when said container is in a storage position.
