Example

[0025]In accordance with a presently preferred embodiment of the present invention, an improved bag 10 can be provided as shown in FIG. 4. One way to construct the bag 10 of FIG. 4 may be understood with reference to the remaining figures.

[0026]Figure 1A shows the start of the creation of inner bag 12 as shown in FIG. 1C. Cotton twill material 14 having 108×56 (weft and warf), 32 mesh, and 100% cotton twill with dimensions of 28×24 is procured for use with a presently preferred embodiment. The material 14 may then be folded along its centerline 16 and the side 18 opposite folded side 20 can be stitched with stitching 22, preferably serge stitches. A first end 24 may / is also preferably stitched, such as with serge stitches 26. Chemical may then be inserted into inner bag 12 through open end 28 or otherwise at this time or later, as will be described below.

[0027]Serge stitches 22,26 have been found to be particularly effective over other stitching methods for many embodiments. In some...

Abstract

An improved water absorbing and retention bag has opposing bands about an outer bag. An inner bag has a supply of super absorbent polymer retained therein. The bands can provide loops from opposing ends of the bag while encircling the bag.

Description

CLAIM OF PRIORITY[0001]This application claims the benefit of U.S. Provisional Patent Application Nos. 61 / 174,523 filed May 1, 2009 as well as 61 / 174,232 filed Apr. 30, 2009. Furthermore, this application is a continuation in part of U.S. patent application Ser. No. 11 / 549,333 filed Oct. 13, 2006.FIELD OF THE INVENTION[0002]The present invention relates to water absorbing and retention bags which can be utilized with, or in place of, sand bags for such uses as flood control, amongst others.DESCRIPTION OF RELATED ART[0003]U.S. Pat. No. such as 6,715,960 and probably others in Class 405 / 114 describe super absorbent polymers (SAPs) utilized in a bag for flood control. However, the applicant has found that when testing products available on the market, the SAPs in the bags normally have a molecular weight less than one (i.e., they float), and they have a tendency to have extremely poor desorption characteristics.[0004]Floodbloc is a company selling a product with a bag available on the ...
