Abstract

A bag construction filled with dispersible material. The bag construction has first and second panel sections, first and second side gusset sections and a bottom gusset panel section. The various panel sections are fastened together to form a generally rectangle shape with a flat bottom. The bottom gusset panel section has one or more distribution apertures in it. A removable panel layer is provided for covering the one or more apertures. When the removable panel layer is removed, the bag can be held so that the dispersible material disperses through the apertures as appropriate.

3. The bag construction in accordance with claim 1 , wherein said removable panel layer includes a peel off layer provided towards said outer surface of said bottom gusset panel section; said distribution aperture being a flap that has a fixed portion fixed to said bottom gusset panel section; and said removable panel layer is configured to be removed from said peel off layer in a peeling direction away from the fixed portion.

4. A bag construction for dispersing dispersible material, comprising:

first and second panel sections with each having bottom and side panel edges;

first and second side gusset panel sections with each having bottom and side gusset edges, one of said side panel edges of each of said first and second panel sections being fastened to one of said side gusset edges of each of said first and second side gusset panel sections;

a bottom gusset panel section with edges, each of said bottom panel edges of said first and second panel sections and said bottom gusset edges of said first and second side gusset panel sections being fastened to a different one of said edges of said bottom gusset panel section to form inner and outer surfaces, said bottom gusset panel section including at least one distribution aperture therein;

a removable panel layer covering said aperture being removably fastened to the outer surface of said bottom gusset panel section wherein when said removable panel layer is fastened in place, said aperture is covered to prevent dispersing the dispersible material, and when said removable panel layer is removed from said bottom gusset panel section, said dispersible material may be dispersed through said aperture; and

a peel off layer provided between said bottom gusset panel section and said removable panel layer, said peel off layer being penetrated through by the distribution aperture; said distribution aperture being a flap that has a fixed portion fixed to said bottom gusset panel section; and said removable panel layer is configured to be removed from said peel off layer in a peeling direction away from the fixed portion, wherein said removable panel layer includes a peel off layer provided towards said outer surface of said bottom gusset panel section; said distribution aperture being a flap that has a fixed portion fixed to said bottom gusset panel section; and said removable panel layer is configured to be removed from said peel off layer in a peeling direction away from the fixed Portion.

5. The bag construction in accordance with claim 4 , including means for fastening together one of said first and second panel sections to a portion of either of said bottom gusset panel section or the other of said first and second panel sections, wherein when some of said dispersible material has been dispersed, said bottom gusset panel can be folded or rolled from one of said edges to an opposite of said edges to cover said aperture and said fastening means used to fasten one of said first and second panel sections to a portion of either said bottom gusset panel section or the other of said first and second panel sections.

6. A method for using a bag construction wherein the bag construction allows for dispersing dispersible material, said bag construction including first and second panel sections with each having bottom and side panel edges; first and second side gusset panel sections with each having bottom and side gusset edges, one of said side panel edges of each of said first and second panel sections being fastened to one of said side gusset edges of each of said first and second side gusset panel sections; a bottom gusset panel section with edges, each of said bottom panel edges of said first and second panel sections and said bottom gusset edges of said first and second side gusset panel sections being fastened to a different one of said edges of said bottom gusset panel section to form inner and outer surfaces, said bottom gusset panel section including at least one distribution aperture therein; and a peel off layer provided between said bottom gusset panel section and said removable panel layer, said peel off layer being penetrated through by the distribution aperture; said distribution aperture being a flap that has a fixed portion fixed to said bottom gusset panel section; and said removable panel layer is configured to be removed from said peel off layer in a peeling direction away from the fixed portion, wherein said removable panel layer includes a peel off layer provided towards said outer surface of said bottom gusset panel section; said distribution aperture being a flap that has a fixed portion fixed to said bottom gusset panel section; and said removable panel layer is configured to be removed from said peel off layer in a peeling direction away from the fixed portion, said method comprising: removing said removable panel layer from covering said aperture; and dispersing through said aperture at least some of said dispersible material.
