Abstract
A reusable, evacuable enclosure comprising a bag (4) with an opening (12) in which to place articles, such as clothing or linen, and a one-way valve in a surface of the bag. The articles may be placed in the bag and sealed from the surrounding environment by placing a seal (8) across the opening. The excess air in the bag may then be removed by placing a cylindrical attachment of a household vacuum cleaner over the one-way valve (6). Once the excess air is extracted, a cap is placed over the valve to ensure a permanent seal.
Removal of excess air and moisture from the bag protects the stored article against insects, bacteria, mildew, corrosion, etc. A variety of seals for closing the bag are described.

Claims (9)
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A one-way valve for use with a conventional vacuum cleaner attachment, said valve comprising:
a valve body containing an air passage;
a flexible diaphragm fixed to said valve body and covering said air passage, said diaphragm for allowing air to pass through said air passage in only one direction; and an annular member formed of a resilient material and fixed to said valve body, a distance between an inside diameter and an outside diameter of said annular member being selected such that an exposed flat surface of said annular member is capable of forming 2a seal with cylindrical vacuum cleaner attachments of various diameters when any one of said attachments is manually pressed against said member on a downstream side of said air passage, thereby permitting said vacuum cleaner to draw air through said air passage, said flat annular member surrounding said flexible diaphragm, said flexible diaphragm being sized and positioned such that said flexible diaphragm is capable of flexing so as to open and close said air passage when any one of said cylindrical attachments is pressed against said member.
a valve body containing an air passage;
a flexible diaphragm fixed to said valve body and covering said air passage, said diaphragm for allowing air to pass through said air passage in only one direction; and an annular member formed of a resilient material and fixed to said valve body, a distance between an inside diameter and an outside diameter of said annular member being selected such that an exposed flat surface of said annular member is capable of forming 2a seal with cylindrical vacuum cleaner attachments of various diameters when any one of said attachments is manually pressed against said member on a downstream side of said air passage, thereby permitting said vacuum cleaner to draw air through said air passage, said flat annular member surrounding said flexible diaphragm, said flexible diaphragm being sized and positioned such that said flexible diaphragm is capable of flexing so as to open and close said air passage when any one of said cylindrical attachments is pressed against said member.
2. The valve of claim 1 wherein said various diameters vary from approximately seven-eights of an inch to approximately one inch.
3. A one-way valve comprising:
a valve body containing an air passage;
a flexible diaphragm fixed to said valve body and covering said air passage, said diaphragm for allowing air to pass through said air passage in only one direction; and a flat annular member formed of a resilient material and fixed to said valve body, said annular member being adapted so as to form a seal with a cylindrical attachment of a vacuum cleaner when said attachment is manually pressed against said member on a downstream side of said air passage, thereby permitting said vacuum cleaner to draw air through said air passage; and a plurality of vanes on an upstream side of said valve body for preventing said air passage from being obstructed when air is being drawn through said air passage, said vanes comprising a plurality of finlike projections which are attached to and extend from said valve body, each of said finlike projections having an outer edge for contacting an object and thereby preventing said object from obstructing said air passage.
a valve body containing an air passage;
a flexible diaphragm fixed to said valve body and covering said air passage, said diaphragm for allowing air to pass through said air passage in only one direction; and a flat annular member formed of a resilient material and fixed to said valve body, said annular member being adapted so as to form a seal with a cylindrical attachment of a vacuum cleaner when said attachment is manually pressed against said member on a downstream side of said air passage, thereby permitting said vacuum cleaner to draw air through said air passage; and a plurality of vanes on an upstream side of said valve body for preventing said air passage from being obstructed when air is being drawn through said air passage, said vanes comprising a plurality of finlike projections which are attached to and extend from said valve body, each of said finlike projections having an outer edge for contacting an object and thereby preventing said object from obstructing said air passage.
4. The valve of Claim 1 wherein a top surface of said flexible diaphragm is substantially coplanar with a top surface of said annular member.
5. The valve of Claim 1 wherein said flexible diaphragm is circular and concentric with said annular member.
6. The valve of Claim 1 wherein said flexible diaphragm is fixed to said valve body at location adjacent a central portion of said diaphragm, said air passage comprising a plurality of holes in said valve body positioned around said location.
7. The valve of Claim 3, wherein each of said vanes comprises a planar member which extends from a bottom surface of said valve body.
8. The valve of Claim 7 wherein each of said vanes is perpendicular to said bottom surface.
9. The valve of Claim 7 wherein said vanes are arranged in a radial pattern around said air passage, each of said vanes extending radially outward from said air passage.
