A packing bag made of a strong cloth material, combined with a tensioning device which facilitates simple but effective adjustment of the volume of the compressible contents therein. A high degree of compression is achieved by placing two substantially rigid, elongated, stiffening members along the sides of the bag and attaching one or two straps thereto with fasteners. The distance between the stiffening members is controlled by the straps, allowing for the alteration of the volume of the bag. The pressure which appears at compression is divided along the sides of the bag because of the stiffening members, and is not confined to the areas where the straps are attached. The bag can be designed with the opening at either end, thus taking the shape of a cylinder, or with the opening at a wider end, thus taking on a conical shape prior to compression and a cylindrical shape after compression. In alternative embodiments of the invention, the opening can be placed between the stiffeners instead of on either end, enabling easier packing of a larger-size bag, or the bag can be designed in the shape of a cone with the opening at the wide end, so that only one strap is required for adjustment of the upper parts of the stiffening members while the lower parts thereof are firmly attached to the bag.

A bag having a variable volume and being substantially cylindrical when substantially fully packed, said bag having an exterior portion, an interior portion and a longitudinal axis, said bag comprising: a flexible sheet material for enclosing and compressing contents within said bag when in use; said flexible sheet material comprising substantially one unitary piece and forming said exterior portion of said bag; said flexible sheet material having two separate portions spaced apart at a substantial distance from one another; two substantially straight, substantially rigid, elongated, stiffening members being disposed and fastened at said two spaced-apart portions of said flexible sheet material; said elongated members each having an elongated axis along the elongation thereof; tensioning means comprising first tensioning means and second tensioning means; said first tensioning means comprising at least one strap means, said at least one strap means having first attachment means attached directly at a first of said substantially straight, rigid, elongated, stiffening members to transfer tension in use from said at least one strap means to said first one of said two substantially rigid, straight, elongated, stiffening members, said tension of said at least one strap means being transferred substantially transversely to said elongated axis of said first one of said two substantially straight, rigid, elongated, stiffening members when said bag is substantially fully packed with compressible contents and with said at least one strap means tensioned; said at least one strap means having second means for attachment attached directly at a second of said substantially straight, rigid, elongated stiffening members to transfer tension from said at least one strap means to said second one of said two substantially straight, rigid, elongated, stiffening members, said tension of said second attachment means being transferred substantially transversely to said elongated axis of said second one of said two substantially rigid, straight, elongated, stiffening members when said bag is substantially fully packed with said compressible contents and with said at least one strap means tensioned; and said second tensioning means being for transferring tension directly to said first stiffening member and substantially transversely to said elongated axis of said first one of said two substantially rigid, straight, elongated, stiffening members when said bag is substantially fully packed with said compressible contents and said second tensioning means tensioned, said second tensioning means being disposed at a position a substantial distance from said first attachment means, said second tensioning means for transferring tension substantially directly and transversely to said elongated axis of said second one of said two substantially rigid, straight, elongated, stiffening members when said bag is substantially fully packed with said compressible contents and said second tensioning means being tensioned at a position disposed from said first attachment means, said two substantially straight, rigid, elongated, stiffening members, disposed and fastened at said two spaced-apart portions, which are disposed at ends of said flexible sheet material for enclosing contents within said bag, whereby said elongated axes of said two substantially rigid, elongated, straight, stiffening members are substantially in appropriate alignment with said longitudinal axis of said bag when said bag is substantially fully packed with said compressible contents and said at least one strap means is tensioned to a predetermined tension, and whereby said compressible contents of said substantially fully packed bag are compressed in use by said tensioning of said at least one strap means to form a substantially cylindrical shape.
