Abstract
Containment bag for an industrial container embraces a non-self-supporting container having a top, sides, and a bottom, which define an interior space; in at least one of the top and sides, at least one opening for introduction of material into the interior space; and for the at least one opening a flap that can be sealed at or beyond the at least one opening. Sealing is provided through at least one of a hook and loop closure system and an adhesive system. The bag can be employed with the industrial container.
Claims22
A containment bag for use in an industrial container having a plurality of sidewalls defining a top and bottom, the bottom being closed and the top being substantially open or able to be opened for accepting bulk materials, with the plurality of sidewalls and the bottom defining an industrial container interior, said containment bag comprising a non-self-supporting bag construction adapted and useful for fitting within and closely lining the industrial container interior with the industrial container supporting the containment bag, being filled with at least one of product material and waste material while fitting within and closely lining the industrial container interior, being sealed and transported in the industrial container after filling, and being dumped, not lifted, from the industrial container, wherein said bag construction has following features:
- a bag top substantially alignable with the top of the industrial container, bag sides, and a bag bottom, which define an interior space of the bag construction, with the bag sides and the bag bottom not having openings or not having openings larger than those afforded by any woven material, when present, used to make at least one of the bag top, the bag sides and the bag bottom;
- an opening in the bag top for introduction of the at least one of the product material and waste material into the interior space of the bag construction;
- a flap as at least part of the bag top, made with a woven or nonwoven material, extending from one of the bag sides to provide a flap base and an extending web, the flap not having openings or not having openings larger than those afforded by any woven material, when present, used to make the flap, which can be sealed against another portion of the containment bag by a sealing system;
- and
- the sealing system, which:
- includes at least one of a hook and loop system, and an adhesive system;
- and
- provides for sealing with the flap on its extending web.
A containment bag for use in an industrial container having a plurality of sidewalls, a top and a bottom, with one of the sidewalls being substantially open or able to be opened for accepting bulk materials and the remaining sidewalls, the top and the bottom being closed to define a side-loading industrial container with a side opening, with the plurality of closed sidewalls, top and bottom defining an industrial container interior, said containment bag comprising a non-self-supporting bag construction adapted and useful for fitting within and closely lining the industrial container interior with the industrial container supporting the containment bag, being filled with at least one of product material and waste material while fitting within and closely lining the industrial container interior, being sealed and transported in the industrial container after filling, and being dumped from the industrial container, wherein said bag construction has following features:
- a first bag side substantially alignable with the side opening of the industrial container, remaining bag sides, a bag top, and a bag bottom, which define an interior space of the bag construction, the remaining bag sides, the bag top, and the bag bottom not having openings or not having openings larger than those afforded by any woven material, when present, used to make at least one of the first bag side, the remaining bag sides, the bag top and the bag bottom;
- an opening in the first bag side for introduction of the at least one of the product material and waste material into the interior space of the bag construction;
- a flap as at least part of the first bag side, extending from one of the remaining bag sides, the bag top or the bag bottom to provide a flap base and an extending web, the flap not having openings or not having openings larger than those afforded by any woven material, when present, used to make the flap, which can be sealed against another portion of the containment bag by a sealing system;
- and
- the sealing system, which:
- includes at least one of a hook and loop system, and an adhesive system;
- and
- provides for sealing with the flap on its extending web.
A containment bag for use in an industrial container having a plurality of sidewalls defining a top and bottom, the bottom being closed and the top being substantially open or able to be opened for accepting bulk materials, with the plurality of sidewalls and the bottom defining an industrial container interior, said containment bag comprising a non-self-supporting bag construction adapted and useful for fitting within and closely lining the industrial container interior with the industrial container supporting the containment bag, being filled with at least one of product material and waste material while fitting within and closely lining the industrial container interior, being sealed and transported in the industrial container after filling, and being dumped, not lifted, from the industrial container, wherein said bag construction has following features:
- bag sides, and a bag bottom, which define an interior space of the bag construction, the bag sides and the bag bottom not having openings or not having openings larger than those afforded by any woven material, when present, used to make at least one of the bag sides and the bag bottom;
- a top opening for introduction of the at least one of the product material and waste material into the interior space of the bag construction;
- a top closure web as part of the bag sides, made with a woven or nonwoven material, extending upward from the bag sides to provide top closure web bases and extending closure webs, the top closure web not having openings or not having openings larger than those afforded by any woven material, when present, used to make the top closure web, wherein the extending closure webs include opposing quadrilateral panel portions and opposing triangular panel portions opposing each other orthogonal to the opposition of the opposing quadrilateral panel portions when the opposing quadrilateral, panel portions are brought together along top portions thereof for sealing against one another to seal the containment bag by a sealing system about a center portion of the top closure web;
- and
- the sealing system, which:
- includes at least one of a hook and loop system, and an adhesive system, but not a zipper;
- and
- provides for sealing with the top closure web along the top portions of the opposing quadrilateral panel portions of the extending closure webs.
