Systems and devices for storing a fluid in a reinforced bladder is disclosed. A flexible bladder is configured to store the fluid. An exoskeleton is configured to conform to and protect the flexible bladder on all sides. The combination of the flexible bladder and the exoskeleton results in the reinforced bladder.

This invention relates to inner-plies for bulk-bags that surprisingly offer not only high thermal resistance, but also high flex-crack resistance. This invention also relates to such bulk-bags made for packaging of flowable materials, aseptic or otherwise, and the process for improving their flex-crack and thermal resistance. Preferably, the packaging is aseptic. More specifically, the inner-ply of the invention comprises a resin blend comprising the Exceed XP resin; an LDPE resin or an ethylene--olefin copolymer (EAO copolymer); or a blend of said LDPE resin and said EAO copolymer, with flex-crack resistance improved in both machine direction and transverse direction, in conjunction with an improved thermal resistance. Thus, in addition to possessing good flex-crack resistance, the bulk-bags can withstand steam sterilization and/or aseptic packaging conditions.

Disclosed herein is an overlap-structured container bag having an inner bag inserted into an outer bag. In the overlap-structured container bag comprises: (A1) weaving fabric used for a container bag of a hollow structure while a plurality of vertical reinforcing portions are formed; (A2) cutting container bag fabric in unit length; (A3) forming at least one of the lateral reinforcing portion on the inner bag when either one of the upper or lower portion of the cut container bag is selected as the inner bag; (A4) placing the inner bag into the outer bag by turning the open end of the outer bag inside out when the other one where the lateral reinforcing portion is not formed is selected as the outer bag.

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.

Apparatus, systems, and methods for housing a bulk material within a flexible container are described herein. In some embodiments, a method includes maintaining a flexible container in an expanded configuration to define an interior volume. A bulk material is conveyed into the interior volume of the expanded flexible container. The flexible container is then moved from the expanded configuration to a collapsed configuration, such that movement of the bulk material within the interior volume is limited.

A water supply and heating system that includes a flexible water tank, a flexible heating carpet and an electrical connection mechanism. The water tank includes a flexible outer layer and separable inflatable and collapsible water bag. The water bag is equipped with a water inlet and outlet hoses for receiving supplying water. The water bag is positioned inside the outer layer and is designed to remain collapsed when and to inflate when filled with water. The outer layer too is designed to inflate when the water bag is filled with the water and to deflate when the water is drained from the water bag. A dry space is defined between the outer layer and the water bag in which the heating carpet is positioned. The heating carpet includes flexible flat electrical heating strips that are connected to the electrical connection mechanism.

In the overlap-structured container bag comprises: (A1) weaving fabric used for a container bag of a hollow structure while a plurality of vertical reinforcing portions are formed; (A2) cutting container bag fabric in unit length; (A3) forming at least one of the lateral reinforcing portion on the inner bag when either one of the upper or lower portion of the cut container bag is selected as the inner bag; (A4) placing the inner bag into the outer bag by turning the open end of the outer bag inside out when the other one where the lateral reinforcing portion is not formed is selected as the outer bag.

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.

Flexible tanks for transporting liquids comprising a flexible bladder to contain liquid, several transverse surge dampening baffles inside the bladder, each baffle comprising several flexible panels, each having a base connected to the inside of the bladder and aligned along a plane transverse to the bladder and an unsupported terminal end opposite the base and adapted to converge with the unsupported portions of adjacent panels in a manner that defines a barrier to fluid flow across the transverse baffle when the bladder is filled; and a connector for interconnecting the terminal ends of the panels. There may be provided a flexible outer bladder of an abrasion resistant material that is adapted to removably receive the inner bladder. There may be provided longitudinal baffles situated between adjacent transverse baffles that define longitudinal compartments with restricted fluid flow there between for dampening lateral fluid surges.
