A one-way valve allows air to be drawn from an air tight container using a vacuum source. When the vacuum source is removed, the one-way valve prevents air from re-entering the container. A pump evacuates air from the container including a housing cooperatively engaging the housing for filter and cap assembly of the one way valve assembly. A seal isolates the pump housing from the cap sealing housing, and a handle is provided to withdrawably evacuate the air from the container.
1. A container comprising: a flexible air tight container having an opening for receiving an item to be stored in the container; an air-tight seal across the opening; a one way valve assembly installed in a surface of the container wherein the assembly allows air to pass out of the container but prevents air from entering the container, the assembly having a filter and cap assembly housing secured to a surface of the container, a cap sealer housing secured to the filter and cap assembly housing, a vacuum sealer valve sealing the container closed when air is removed from the container, and a support sleeve snap-on securing and retaining the vacuum sealer valve in a closed air-tight condition.
2. A receiving container having a body portion, a sealing edge disposed along an opening in the body portion, and an airtight valve at a selective position on the body portion comprising: a housing for filter and cap assembly fixedly secured to the body portion; a cap sealer housing releasably secured to the housing for filter and cap assembly; a vacuum sealer valve sealing the container closed when air is removed from the container; and a support sleeve snap-on securing and retaining the vacuum sealer valve in a closed air-tight condition.
3. The one way valve assembly as claimed 1 further comprising: a pump for evacuating air from the container including a housing cooperatively engaging the housing for filter and cap assembly of the one way valve assembly, sealing means sealably isolating the pump housing from the cap sealing housing, and a handle withdrawably movable to evacuate the air from the container.

1. Field of the Invention
The present invention generally relates to the field of evacuable containers for storing air sensitive food and medicine as well as storing compressible articles such as clothing.
2. Background of the Prior Art
Storage containers typically include an air-tight bag, an opening through which to put an article in the bag, and a fixture through which to evacuate excess air. A user places an article into the bag through the opening, seals the opening, and then evacuates the air in the bag through the fixture. With the bag thus evacuated, the article contained therein may be significantly compressed so that it is easier to transport and requires substantially less storage space.
Evacuable storage containers are beneficial for reasons in addition to those associated with compression of the stored article. For example, removal of the air from the storage container inhibits the growth of destructive organisms, such as moths, silverfish, and bacteria, all of which requiure oxygen to survive and propogate. Moreover, such containers, being impervious to moisture, inhibit the growth of mildew.
Large, compressible items such as clothing may be stored in a collapsible, evacuable storage container. For example, it may be desirable to store bulk items made of small particles, such as powders or granulated resins, in an evacuated container. One situation that commonly occurs is that a particular bulk item is shipped in a large, rigid container such as a drum. Bulk items may be moisture sensitive and are sealed against moisture during shipment. But many times a user does not need to use the entire contents of the large container, and so once exposed to air the remaining bulk contents quickly become unusable are thus wasted.
A flexible container has a body portion, a sealing edge disposed along an opening in the body portion and an airtight at a selective position on the body portion. The valve has a housing for filter and cap assembly secured to the surface of the container and a cap sealer housing secured to the filter and cap assembly. A vacuum sealer valve seals the container closed when air is removed from the container, and a support sleeve snap-on secures and retains the vacuum sealer valve in a closed air-tight condition.
The invention also includes a pump for evacuating air from the container including a housing cooperatively engaging the housing for filter and cap assembly of the one way valve assembly. A sealing device isolates the pump housing from the cap sealing housing, and a handle is withdrawably movable to evacuate the air from the container
Referring now to the drawings and particularly to
A cap sealer housing 28 is threadably connected to assembly 20 and engages washer 26 to secure all members to pouch 10 and against each other. A vacuum sealer valve 30 is positioned to open when air is removed from pouch 10 and close when air is evacuated from pouch 10. A support sleeve snap-on mechanism 32 holds sealer valve 30 in a pouch closed positioned after air has been removed. A filter 34 is positioned in the interior of assembly 20 as shown in
A pump shown generally as 36 in
When pump 36 is operated to remove air from pouch 10, pump housing legs 52 can be squeezed toward each other and dislodge legs 52 from underneath the flange of washer 26 and thereby release pump 36 from its connection with housing 28.
A number of other containers can be used for storage in an air free condition such as the rectangular container 54 shown in
A pictorial illustration of the operation of the present invention is included herein as
From the preceding description, it can be seen that an evacuable storage container has been provided that will meet all the advantages of prior art devices and offer additional advantages not heretofore achievable. With respect to the foregoing invention, the optimum dimensional relationship to the parts of the invention including variations in size, materials, shape, form, function, and manner of operation, use and assembly are deemed readily apparent to those skilled in the art, and all equivalent relationships illustrated in the drawings and described in the specification are intended to be encompassed herein.
The foregoing is considered as illustrative only of the principles of the invention. Numerous modifications and changes will readily occur to those skilled in the art, and it is not desired to limit the invention to the exact construction and operation shown and described. All suitable modifications and equivalents that fall within the scope of the appended claims are deemed within the present inventive concept.
