Disclosed herein is an insert-structured container bag having an inner bag inserted into an outer bag. In the insert-structured container bag having an inner bag inserted into an outer bag according to an aspect of the present invention, the inner bag includes one or more lateral reinforcing portions formed by folding the inner bag; the outer bag includes vertical reinforcing portions formed on the respective side surfaces of the outer bag, lifting loops coupled to the tops of the vertical reinforcing portions, and a connection portion passed through the lifting loops, and the lateral reinforcing portions are formed by folding the inner bag outward in a lateral direction, and are disposed in a space between the inner bag and the outer bag.

Disclosed are various embodiments of a collapsible containment bag configured to retain a collection of hazardous materials. In one embodiment, the containment bag includes a non-porous liner, a plastic sheeting, and a bag frame. The containment bag may be in a collapsed state initially and later expand for use at the site of an environmental spill. The containment bag may be expanded from the collapsed state through a series of actions that may include pivoting a portion of the containment bag about an edge and pulling opposing sides of the containment bag away from the center of the containment bag.

A flexible storage device for packaging particulate solid substances or liquids, having a bottom and lateral walls defining a storage volume, includes: hanging loops toward the top intended for lifting an assembly including: a flexible external wrapper forming at least the four lateral walls of the storage volume, a flexible tubular internal wrapper secured to the four lateral walls of the external wrapper, dividing the storage volume into five vertical compartments including a central compartment defined by the interior volume of the internal wrapper, and four peripheral compartments defined between the lateral walls of the external wrapper and the lateral walls of the internal wrapper. The internal wrapper has an upper edge defining the upper mouth of the central compartment and a lower edge defining the lower mouth of the central compartment. The upper edge of the internal wrapper is at or below the upper edge of the lateral walls.

A bulk packaging product is described herein. The packaging product includes: trilayered walls in the shape of a rectangular package that can contact a product; wherein the package includes 4 walls; a plurality of baffles attached to two adjacent walls within the package that help maintain the rectangular shape; a plurality of lifting loops attached to at least two corners of the package; and an opening to facilitate filling the package with product.

The invention relates to a transport bag comprising a base, a top portion, and side walls extending between said base and top portion in such a way that a volume for storing granule, fluid, viscous, or semi-fluid materials is formed, wherein the transport bag comprises at least one narrowed portion extending through a middle axis of said side wall from a upper edge to a bottom edge of the side wall.

The invention is directed to a bag for transporting and handling powdery bulk materials, especially inorganic or organic pigments. Further, the present invention relates to a method for opening the tubular drain of such a bag, as well as to the use of the bag for transporting and handling powdery bulk materials.

A liner (L) has a liner body (11) with a front wall (12), rear wall (16), bottom wall (13), a top wall (14). The top wall also includes a tubular excess liner material or chute (19) located close to the rear wall and which includes a filling fitment (20) with a fitment cap (21). The liner also has a cylindrical, hose content inlet/outlet port or bottom fitment (23). The liner may include a gap-filler or filler strip (90) of foam material extending outwardly from a position closely adjacent the outlet fitment. The filler strip is mounted to the front wall and/or top wall. The filler strip may taper so that at least a majority of the strip's longitudinal length or height so as to increase in its lateral width as it approaches the outlet fitment, thereby increasing the material volume of strip material.

A liner L has a liner body 11 with a front wall 12, rear wall 16, bottom wall 13, a top wall 14. The top wall also includes a tubular excess liner material or chute 19 located close to the rear wall and which includes a filling fitment 20 with a fitment cap 21. The liner also has a cylindrical, hose content inlet/outlet port or bottom fitment 23. The liner may include a gap-filler or filler strip 70 of foam material extending outwardly from a position closely adjacent the outlet fitment. The filler strip is mounted to the front wall directly over and closely adjacent the outlet fitment. The filler strip may taper so that at least a majority of the strip's longitudinal length or height so as to increase in its lateral width as it approaches the outlet fitment, thereby increasing the material volume of strip material.

The invention relates to a transport bag comprising a base, a top portion, and side walls extending between said base and top portion in such a way that a volume for storing granule, fluid, viscous, or semi-fluid materials is formed, wherein the transport bag comprises at least one narrowed portion extending through a middle axis of said side wall from a upper edge to a bottom edge of the side wall.

A system, method and apparatus for transferring bulk material for transport, the method includes placing a first quantity of bulk material in a soft-sided bulk material container, extending a first hold-in across the container from a first side of the container to a second location, the second location being substantially toward a second side of the container, wherein the first hold-in is secured to the first side of the container, securing the first hold-in to the second location and placing a second quantity of bulk material in the container, the second quantity covering the first hold-in and securing the first hold-in to the second location with a weight of the second quantity of bulk material.
