Reusable, evacuable enclosure for storage of clothing and the like

A container comprising:

• a) a flexible, air-tight bag having an opening for inserting into said bag an item to be stored;
• b) a reusable seal for providing an air-tight seal across said opening;
• and
• c) a valve body for supporting a one-way valve, said body installed in a surface of said bag and comprising a valve seat and one or more holes that allow air to pass through said body, wherein said one-way valve allows air to pass out of said bag and prevents air from entering said bag,
• wherein said reusable seal comprises:
• a) a first strip having an elastic slot of C-shaped cross-section running the length of said first strip along a first surface of said first strip;
• b) a second strip running parallel to said first strip, said second strip having a ridge perpendicular to a second surface of said second strip and parallel to said first strip, and a substantially tubular elastic flange along the length of said ridge, said flange having a slit opposite said ridge and running the length of said flange;
• c) a hinge of semi-circular cross-section such that said hinge has an inside surface and an outside surface, said hinge joining said first strip and said second strip and running parallel to and between said first strip and said second strip, said hinge comprising a plurality of channels formed in said inside surface and running parallel to said first strip and said second strip, each of said channels having a substantially triangular cross-section such that each of said channels is widest at its bottom surface and narrowest at said inside surface;
• d) wherein said first surface and said second surface converge when said reusable seal is folded along said hinge so that said slot and said flange snap together;
• e) wherein portions of said inside surface separating said plurality of channels meet when said slot and said flange mate;
• and
• f) wherein said opening may be sealed by positioning said bag such that when said slot and said flange mate, bag material surrounding said opening is trapped between said slot and said flange.

A reusable closure for forming a seal between a plurality of flexible layers, said closure comprising:

• a) a first strip having a slot running along a surface of said first strip;
• and
• b) a second strip having a bifurcated flange running along a surface of said second strip, said bifurcated flange comprising a first ridge and a second ridge, each of said first and second ridges having a generally convex outside surface which extends substantially the entire distance from a base of said ridge to a tip of said ridge, the tips of said first and second ridges being separated by an opening;
• wherein said slot and said bifurcated flange are sized such that said bifurcated flange fits within said slot, the generally convex outside surface of each of said ridges pressing against a concave interior surface of said slot when said slot and said bifurcated flange are fitted together.

A storage container comprising:

• a) a bag comprising a flexible material and having an opening for inserting into said bag an item to be stored;
• b) a reusable closure which firms a seal across said opening;
• and
• c) a one-way valve installed in a surface of said bag so as to allow air to pass out said bag and prevent air from entering said bag through said one-way valve;
• wherein said reusable closure comprises:
• d) a first strip having a slot running along a surface of said first strip;
• and
• e) a second strip having a bifurcated flange running along a surface of said second strip, said bifurcated flange comprising a first ridge and a second ridge, each of said first and second ridges having a generally convex outside surface which extends substantially the entire distance from a base of said ridge to a tip of said ridge, the tips of said first and second ridges being separated by an opening, said slot and said bifurcated flange being sized such that said bifurcated flange fits within said slot, the generally convex outside surface of each of said ridges pressing against a concave interior surface of said slot when said slot and said bifurcated flange are fitted together;
• wherein said flexible material is trapped between said bifurcated flange and said slot so as to form said seal across said opening.

A storage container comprising:

• a) a flexible bag having an opening for inserting into said bag an item to be stored;
• b) a seal across said opening;
• and
• c) a one-way valve installed in a surface of said bag so as to allow air to pass out of said bag and prevent air from entering said bag through said one-way valve;
• wherein said seal comprises:
• a) a first strip having a slot running along a first surface of said first strip;
• b) a second strip having a flange running along a second surface of said second strip, said flange fitting into said slot so as to trap said flexible bag between said flange and said slot;
• c) said first and second strips being joined by a hinge, said hinge comprising a flexible member, a plurality of parallel channels being formed in a third surface of said flexible member, each of said channels having a cross-sectional shape which includes a relatively narrow opening at said third surface and a relatively wide dimension nearer a bottom of said channel, said relatively narrow opening being bounded by a pair of edges of said third surface, wherein said hinge is capable of flexing between a first open condition and a second closed condition and wherein said pair of edges meet when said hinge is in said second closed condition.
