Abstract: A container closed at one end by a supporting surface includes a vertical tubular inner member and an outer envelope secured to the outside of the inner member. The outer envelope comprises at least four vertical partial tubular outer members equal in vertical length to and parallel to the inner member, the partial tubular outer members having an open arc-shaped cross-section with free ends at either side of the arc, each outer member being secured along both of its free ends to the outside of the inner member. The radius and location of each of the outer members relative to that of the inner member are such that, viewing the container in cross-section, four lines may be drawn, each line drawn through at least two tangent points on the outer members with at least two of the lines being parallel and intersecting tangent points on the inner member, the four lines intersecting to form a rectangle, which rectangle encloses the entire outside perimeter of the container.

Abstract: The container comprises a relatively stiff, form-retaining supporting frame and a flexible shell member. The supporting frame comprises a polygonal bottom member and a corresponding cover member. Each angular point of the bottom member is connected with an angular point of the cover member by means of a rod-shaped element. The flexible shell member is connected with each rod-shaped element by means of a flexible loop member. Each loop member starts from a point of attachment to the shell member and passes around a rod-shaped element to a second point of attachment. The arrangement is such that the loop members keep the shell member within the outer boundaries of the supporting frame at all times, at least if the shell member contains goods to be packaged. According to the invention, a strip-shaped member made from a flexible material is connected with the shell member at the points of attachment.

Abstract: A container for bulk materials, fluids and the like, comprising an enveloping member and an inner member which is connected to the enveloping member at at least four positions spaced along the circumference of the enveloping member, the arrangement being such that in filled condition a substantially block-shaped unit with substantially flat walls is obtained, the container further comprising a U-shaped stiffening member which comprises a web and two legs connecting thereto and is made of a material with a stiffness of its own, arranged so that the legs abut two opposite walls of the block-shaped unit and the web abuts the bottom wall of the block-shaped unit, the legs, at least in the areas adjacent their free upper edge, having a width corresponding substantially to that of the adjacent wall of the block-shaped unit and the U-shaped stiffening member being connected to the enveloping member at least in the areas referred to.

Abstract: The invention concerns a package for transporting and storing bulk goods, said package comprising an outer package (11) and an inner package (12). The inner package (12) comprises an outer frame (13) and an inner frame (14) which are at least partly attached to each other. The length of the outer frame (13) of the inner package (12) is greater than or equal to the length of the inner frame of the outer package (11), and the length of the inner frame (14) of the inner package (12) is smaller than or equal to the length of the outer frame of the outer package (11). The internal pressure (P.sub.1) prevailing in the package (10) is received as tension force (F.sub.2) acting on the circumference of the outer package (11), said tension force producing a resultant force (F.sub.3) acting from the corners of the outer package (11) on the package (11), said resultant force (F.sub.

Abstract: A container is provided, which comprises a supporting frame including rod-like elements of a relatively rigid, dimensionally stable material, and a flexible sleeve member forming a receptacle for substances, materials, goods and the like to be packaged. The supporting frame includes at least three circumferential planes, a top plane and a bottom plane. A rod-like element is provided at the transition of a circumferential plane to an adjacent circumferential plane. The sleeve member is provided with at least three flexible loop members each extending around a rod-like element and being attached to the sleeve member at two places spaced apart in the circumferential direction of the sleeve member. Each loop member has a length, measured from one place of attachment to the sleeve member to the other, which is a multiple of the circumference of the enveloped rod-like element.

Abstract: A container for fluids, solids having flow properties or the like, and comprising a box of a conventional packing material, such as cardboard, a supporting frame of a material that is stronger and of greater dimensional stability, such as wood, and an inner bag (4) of a conventional packing material, such as a flexible synthetic plastics, for containing the material being packed. The container comprises four opposed frame sidewalls (1, 2), each including a pressure face (8, 13) extending the full height of the respective sidewall. A sleeve (3) of a relatively thin material having a high tensile strength and relatively low stretch, such as paper, a ribbon fabric of plastics, or the like, is provided to extend on the outside of, and around, the pressure faces (8, 13), and from one side of a pressure face (8, 13) substantially direct to the adjacent side edge of the pressure face (13, 8) of the adjacent sidewall, thus cutting the frame corners.

Abstract: A container for free-flowing, fluid and like materials, comprising a tubular outer envelope (1; 4; 7; 13; 17) that can be closed at both ends and a tubular inner member (2; 5; 8; 14; 18) which at at least four positions spaced about the circumference of the tubular outer envelope is connected to said outer envelope, said inner member having a length that is 30-100% of the height of the container. Said container further comprises stiffening means (3; 6; 10; 15; 19) extending throughout the entire height of the container, having a relatively high stiffness or tear resistance of their own, and extending substantially in contact with the inner member. Said stiffening means can be a tube (3; 6) telescoped within the inner member or substantially rigid stiffening members (10; 15; 19) inserted into pockets formed adjacent a joint (9) between the outer envelope and the inner member and extending lengthwise of the container.

Abstract: A container for free-flowing materials, powders, pellets and the like, comprising a tubular outer envelope that can be closed at both ends and a tubular inner member having a circumference less than that of the outer envelope. The tubular inner member is connected to the outer envelope at at least four positions spaced circumferentially of the outer envelope and in the longitudinal direction of the tubular shapes, and has a length that is 30-100% of the selected height of the container.
