The invention described herein generally pertains to a system and method related to a hermetic seal assembly used with a bag to provide a hermetic seal for the bag that can be opened and closed while maintaining the hermetic seal for the bag and materials stored therein. The hermetic seal assembly can include a lid and a collar, wherein the collar can be releasably affixed to the bag or integrated into an opening of the bag.

This disclosure relates generally to a storage tank for storing a fluid, such as water, oil and other high volatile liquid material having a wall defined by a plurality of panels which are retained by opposed side edges between adjacent support members. The support members have a base portion and a support portion and are free-standing on the base portion on an earthen floor allowing the tank to be constructed at sites without concrete foundations such as a concrete pad or ring. The tank also has a liner that lines the interior surfaces of the wall and the floor. The main embodiment of the invention is based on a design where the storage water tank is divided by a rubber membrane balloon from one side of the tank. The rubber balloon membrane act as storage for one type of liquid and will divide the single tank to act as two separate tanks with the ability to operate independently in terms of storage, water/liquid intake and water/liquid output through given connected inlet & outlet pipes. The concept is to provide each half of the tank as a full tank from input and output separated by a rubber balloon membrane also acting as a storage device within the tank.

An energy or water storage system can comprise a storage reservoir, a discharge reservoir, a pump for charging the storage reservoir, and a turbine or similar discharge device. The storage reservoir can comprise a flexible bag covered by overburden that creates pressure inside the bag. Energy is stored by raising the overburden. The bag can comprise a shaped internal filler piece to prevent formation of a crease at the bag edge. Solar panels can be mounted above any bag to make additional use of the land. Solar panels mounted on overburden can have tracking mechanisms and controls suitable to achieve desired orientation regardless of the slope of overburden. Elevation difference between the storage reservoir and discharge reservoir can be used, including an underground cavity. The bag can have internal tethers to influence bag shape.

An exterior cover of a generally rectangular flexible tank for a 40 foot shipping container has longitudinal seams along the long sides of the flexible tank rather than at the ends. The exterior cover is air-tight and contains holes near the ends of the flexible tank. The exterior cover is made of a flexible vinyl material that is optimized for the flexitank. The flexible vinyl material consists of an inner scrim core of woven fibers coated with melted PVC which goes through the holes between the woven fibers.

The present invention relates to a flexible big bag (10) provided for carrying liquid or liquid based material, stored therein, in a vehicle chassis or in a container, and having a first layer (101) which defines a closed volume.

The invention relates to plastic film preferably with a thickness of 50 to 300 microns, comprising a polyolefin homopolymer or copolymer, a polyether copolymer having a melting point between 100° C. and 120° C. and a layer comprising oxygen barrier polymer.

A system for holding multiple beverage containers may include a cooler or carrier with toting handles, closing tabs, and base. The base may be formed from a molded plastic, rubber or synthetic rubber material. The base may also include feet that hold the base a sufficient height from the ground. The base may have a generally conic tapering drain floor that makes up its top surface. The tapering drain floor may make draining the carrier easier by directing water toward a drain hole located in the base. Extending up from the base may be a multi-layer soft-sided wall where different layers perform different desired functions. For example, an inside layer closest to the internal cavity may be a waterproof layer, a middle layer may be an insulating layer, and an external layer may be a decorative layer.

A packaged article is composed of a bulk bag having a top end and a bottom end. Further included is a pallet having a first side and a second side. Also included are an outer bag having a first closed end and a first open end and a heatshrink bag having a second closed end and a second open end. The first closed end of the outer bag is between the bottom end of the bulk bag and the first side of the pallet. The first open end of the outer bag is gathered over the top end of the bulk bag to enclose the bulk bag within the outer bag. The second closed end of the heatshrink bag is proximate to the top end of the bulk bag and the second open end contacts the second side of the pallet.
