Description

DESCRIPTION
This invention relates to the collection of construction waste materials with a Flexible Intermediate Bulk Container. For the purposes of this description, the term "bulk container" and the term "bag" shall be interchangeable.

A flexible intermediate bulk container (FIBC) is defined as an intermediate bulk container, having a body made of flexible fabric, which = Cannot be handled manually when filled;
= Is intended for shipment or movement of solid material;
= Does not require further packaging;
= Is designed to be lifted from the top by means of integral, permanently attached devices (lift loops or straps) Flexible intermediate bulk containers (FIBCs), also known as "big bags," "bulk bags," and "bulk sacks," were first manufactured in the late 1950s or early 1960s. It is known that FIBCs were made in the United States, Europe, and Japan during the time period mentioned above. The first FIBCs were constructed with heavy-duty PVC-coated nylon or polyester where the cut sheets are welded together to form the FIBC. These FIBCs were made with integrated lift slings around the container, or attached to a specially made pallet, or a metal lifting device that the container sat on. The handling devices allowed the container to be filled from the top and discharged from the bottom.

The initial cost of these heavy-duty PVC containers is high; therefore, they are designed to be reused many times.

Flexible intermediate bulk containers manufactured with polyolefin fabrics were experimented with in England, Japan, Canada, and the United States all at about the same time in the late 1960s to the early 1970s. It was the development of these high-strength light weight fabrics (i.e., polypropylene) that spurred the growth of the flexible intermediate bulk bags that are universally used today.

The flexible bulk container offers features that are unique to this package.
It can be folded flat and bailed for shipment to the user. The cost of FIBCs is competitive with other forms of packaging as it is usually utilized without pallets.
They are easy to store and handle in warehouses with standard equipment.

FIBCs generally are manufactured to meet specific requirements of the container users. The height of the container, the diameter and length of the spouts, coated or uncoated fabric, and whether a polypropylene liner is necessary will be specified according to the type of product that will be transported.

Typical Flexible Intermediate Bulk Containers of this type are shown, for example, in the following Canadian patents:

CA 2138576 Gallie and Thorpe CA 2005867 Strand and Omdal CA2047725 Juel, Strand, Omdal and Lysfjord CA2005662 Strand Though such Flexible Intermediate Bulk Containers have achieved considerable approval and commercial use, there has been a continuing need for improvement.

As the legislation is new regarding this process, I have devised a system and product that will make collection and disposal of construction waste materials safe, inexpensive and effective. My bag has a series of loops allowing the extraction by boom picker truck and the support of a bag stand. These bags can be stand-alone entities in the field.

I have found that all of the innovative features of my bag overcome all obstacles in the support and collection process. The top loops allow the picker boom truck operator to remotely connect on to and safety extract the bag from the stand and the interior loops sole purpose is to allow the bag to be supported freely and in a manner conducive to the ease of collection.

In drawings which illustrate embodiments of the invention, Figure 1 is an elevated corner view of the entire open bag ready to be emptied. Figures 1 A, 1 B, 1 C
and 1 D are close-up sectional views of components in Figure 1. Figure 2 is also an elevated corner view of the entire open bag ready to be emptied. Figures 2A, 2B, 2C and 2D are close-up sectional views of components in Figure 2.

The invention is a bulk container having four top lifting straps B for lifting and transporting the container. These straps are sewn vertically onto the body of the bag at each corner forming an inverted "U shape" and into the reinforced top edging the bag.
The invention also has four stand loops A in Figure 1 sewn just below the lifting straps and onto the vertical interior of the bag to allow the bag to be supported by the bag stand apparatus. Figure 1 shows the bag with the section of the bag secured by E ready to be tucked upward with the flap which is attached to the straps D about to be folded up to secure to the Cam Buckles C. The sides and bottom of the bag are now supported by straps D with quick connect Cam Buckles C. The bulk container is now ready to be placed on the stand ready to be filled with waste. This system allows for additional side support and an easy way of emptying the bag. The open bottom of the bulk container shall be secured with a pull cord E. The additional option to this invention is the same bulk container having four top lifting straps B for lifting and transporting the container.
These straps are sewn vertically onto the body of the bag at each corner forming an inverted "U shape" and into the reinforced top edging the bag. The option version of this invention has four stand rings, comprised of metal, A in Figure 2 sewn just below the lifting straps and onto the vertical interior of the bag to allow the bag to be supported by the bag stand apparatus. Figure 2 shows the bag with the section of the bag secured by E ready to be tucked upward with the flap which is attached to the straps D
about to be folded up to secure to the Cam Buckles C. The sides and bottom of the bag are now supported by straps D with quick connect Cam Buckles C. The bulk container is now ready to be placed on the stand ready to be filled with waste. This system allows for additional side support and an easy way of emptying the bag. The open bottom of the bulk container shall be secured with a pull cord E.

The lifting strap is comprised of a material loop sewn onto the outside portion of each corner of the bulk container with the stand loop sewn slightly below the lifting strap on the inside of the bulk container.

The body of the Flexible Intermediate Bulk Container is made of flexible strong polypropylene woven material. This material provides a safe, sturdy and easy-to-clean bag that will be utilized in all of the construction waste removal applications. The bottom pull cord is also made of a polypropylene woven material. The flexible bulk container material offers the ability that it can be folded and bailed for ease and cost-effectiveness of shipment.

This invention provides a safe and effective way of recycling construction waste materials.
