First Claim
Patent Images
1. A multi-compartment, flexible container, comprising:
- a first compartment, said first compartment being suitable for receiving a first granular material therein;
a second compartment, said second compartment being suitable for receiving a second granular material therein, wherein a border of the second compartment is adjacent the first compartment and where the first compartment and the second compartment are formed between flexible film layers;
a frangible, non-resealable seal separating the first and second compartments to initially prevent opening between the first and second compartments, said frangible seal being the result of the adhesion of the flexible film layers, wherein said frangible seal includes a V-shaped stress concentrating feature facilitating an initial separation of said frangible seal; and
at least one external tab, operatively associated with an external surface of one of said flexible film layers, said tab positioned at a tip of said V-shaped stress concentrating feature to externally apply a tensile force to the stress concentrating feature of the frangible seal for separating the frangible seal,wherein at least one of said first or second compartments includes a vapor permeable region where gas escapes the package through the vapor permeable region.

15. A multi-compartment, flexible container, comprising:
-
a first compartment suitable for receiving a first material therein; a second compartment suitable for receiving a second material therein, wherein a border of the second compartment is adjacent the first compartment and where the first compartment and the second compartment are formed between flexible film layers; a frangible, non-resealable seal separating the first and second compartments to initially prevent opening between the first and second compartments, said frangible seal being the result of the adhesion of the flexible film layers, wherein said frangible seal includes a V-shaped stress concentrating feature; and at least one external tab, operatively associated with the container, said tab positioned at a tip of the V-shaped stress concentrating feature of the frangible seal for separating the frangible seal, wherein at least one of said first or second compartments includes a vapor permeable region in the form of a fitment, said fitment having a gas permeable membrane therein, and where gas is directly exchanged through the gas permeable membrane and thereby escapes the package. - View Dependent Claims (16, 17, 18, 19)

20. A multi-compartment, flexible container, comprising:
-
a first compartment suitable for receiving a first solid material therein; a second compartment suitable for receiving a second solid material therein; said first and second compartments being separated by at least one seal; a third compartment, adjacent the first compartment and the second compartment, said third compartment of a size suitable for receiving the first and second materials from said first and second compartments, where the third compartment includes a vapor permeable region; and a frangible, non-resealable seal between the third compartment and both of the first and second compartments to initially prevent opening between the said third compartment and the first compartment or the second compartment, respectively, wherein said frangible seal includes a V-shaped stress concentrating feature; at least one external tab, operatively associated with the container and applied to an outer surface thereof at a location at a tip of the V-shaped stress concentrating feature of the frangible, non-resealable seal, and wherein said external tab also serves as a handle suitable for carrying the container.
