Storage bags having two or more evacuable reclosable compartments. Each compartment can be opened (to allow an article or goods to be placed inside), hermetically sealed, and then evacuated without disturbing the vacuum in the other compartment(s). Each compartment has a respective zipper that provides a hermetic seal and a respective valve through which air is exhausted from the compartment interior.

The invention claimed is: 1. A compartmented storage bag comprising first and second zippered compartments connected to a double valve assembly therebetween, said double valve assembly comprising first and second valve entry gaps, first and second collapsible channels and an outlet, an interior space of said first compartment being in flow communication with the ambient atmosphere via said first valve entry gap, said first collapsible channel and said outlet when said first valve entry gap and said first collapsible channel are open and said first zipper is closed, and being not in flow communication with the ambient atmosphere when said first collapsible channel and said first zipper are closed, and an interior space of said second compartment being in flow communication with the ambient atmosphere via said second valve entry gap, said second collapsible channel and said outlet when said second valve entry gap and said second collapsible channel are open and said second zipper is closed, and being not in flow communication with the ambient atmosphere when said second collapsible channel and said second zipper are closed, wherein said double valve assembly comprises first and second valve strips which are joined together to form said first and second valve entry gaps and said first and second collapsible channels, and wherein said outlet comprises an opening formed in said first valve strip. 2. The compartmented storage bag as recited in claim 1, wherein each of said first and second zippered compartments comprises front and rear walls, and said first and second valve strips are made of a material that is smoother than the material of said front and rear walls. 3. The compartmented storage bag as recited in claim 2, wherein said first and second collapsible channels are mutually parallel. 4. A compartmented storage bag comprising first and second sheets of thin flexible material that extend from a first side seam to a second side seam, a first plastic zipper that extends from said first side seam to said second side seam and is joined to first marginal portions of said first and second sheets, a second plastic zipper that extends from said first side seam to said second side seam and is joined to second marginal portions of said first and second sheets, said first and second zippers being generally parallel when said first and second sheets are arranged in a planar configuration, and first and second valve strips that extend from said first side seam to said second side seam in a region located between said first and second zippers, said first and second valve strips being sandwiched between said first and second sheets and being joined to each other and to said first and second sheets in the areas where said first and second side seams overlap with said first and second valve strips and in first and second zones of joinder which extend from said first side seam toward but short of said second side seam, the ends of said first and second zones of joinder being separated from said second side seam by first and second valve entry gaps respectively, said first valve strip being joined to said first sheet along said first and second valve entry gaps, said second valve strip being joined to said second sheet along said first and second valve entry gaps, and said first and second valve strips being not joined to each other along said first and second valve entry gaps, and said first and second valve strips being further joined to each other in a third zone of joinder which is located between said first and second zones of joinder and extends from said second side seam toward but short of said first side seam, said first and second valve strips being separable in a region between said first and third zones of joinder for forming a first collapsible channel, further comprising overlapping openings in said first sheet and said first valve strip, said overlapping openings being disposed in a region that extends between said first side seam and an end of said third zone of joinder. 5. The compartmented storage bag as recited in claim 4, wherein said first and second valve strips are further joined to each other in a fourth zone of joinder which is located between said second and third zones of joinder and extends from said second side seam toward but short of said first side seam, said first and second valve strips being separable in a region between said second and fourth zones of joinder for forming a second collapsible channel, wherein said region in which said overlapping openings are disposed extends between said first side seam and an end of said fourth zone of joinder. 6. The compartmented storage bag as recited in claim 5, wherein a first space between respective portions of said first and second sheets and bounded by said first and second side seams, said first zipper and said first zone of joinder will be in flow communication with said overlapping openings when said first valve entry gap and said first collapsible channel are open, and will not be in flow communication with said overlapping openings when said first valve entry gap and said first collapsible channel are closed, and a second space between respective portions of said first and second sheets and bounded by said first and second side seams, said second zipper and said second zone of joinder will be in flow communication with said overlapping openings when said second valve entry gap and said second collapsible channel are open, and will not be in flow communication with said overlapping openings when said second valve entry gap and said second collapsible channel are closed. 7. The compartmented storage bag as recited in claim 5, wherein said first and second collapsible channels are mutually parallel. 8. The compartmented storage bag as recited in claim 4, wherein a first space between respective portions of said first and second sheets and bounded by said first and second side seams, said first zipper and said first zone of joinder will be in flow communication with said overlapping openings when said first valve entry gap and said first collapsible channel are open, and will not be in flow communication with said overlapping openings when said first valve entry gap and said first collapsible channel are closed. 9. The compartmented storage bag as recited in claim 4, further comprising a first slider mounted to said first zipper and designed to close any open section of said first zipper that said first slider overrides during travel of said first slider along said first zipper in either direction, and a second slider mounted to said second zipper and designed to close any open section of said second zipper that said second slider overrides during travel of said second slider along said second zipper in either direction. 10. The compartmented storage bag as recited in claim 4, wherein said first and second valve strips are made of a material that is smoother than the material of said first and second sheets.
