Definitions
- the present invention provides an interface on a pump for docking to a fitment of a vacuum storage container and pumps for use with vacuum storage containers.
- Vacuum storage containers come in numerous shapes, styles and sizes and include flexible bags, semi-rigid and rigid type containers.
- Collapsible, evacuable storage containers typically include a flexible, fluid-tight bag, an opening through which to place an article or food item in the bag, and a fixture through which to evacuate excess air.
- a user places an article into the enclosure through the opening, seals the opening, and then evacuates the fluid through the fixture. With the chamber thus evacuated, the article contained therein may be significantly compressed, so that it is easier to transport and requires substantially less storage space.
- storage life can be increased by removing air from the container and by maintaining this reduced oxygen environment.
- Collapsible, 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, which require oxygen to survive and propagate. Moreover, such containers, being impervious to moisture, inhibit the growth of mildew.
- United States Patent Application Publication No. 2007/0209326 A1 discloses an evacuable, food storage container having a one way valve for access by an electric vacuum pump.
- U.S. Pat. Application No. 7,178,555 B2 discloses a pressure relief valve for flexible storage containers.

Abstract
Description
- This application claims priority to U.S. Provisional Patent Application Ser. No. 60/899,513 filed on Feb. 5, 2007, which is incorporated herein by reference in its entirety and made a part hereof.
- Not Applicable.
- 1. Technical Field
- The present invention provides an interface on a pump for docking to a fitment of a vacuum storage container and pumps for use with vacuum storage containers. Vacuum storage containers come in numerous shapes, styles and sizes and include flexible bags, semi-rigid and rigid type containers.
- 2. Background Art
- Collapsible, evacuable storage containers typically include a flexible, fluid-tight bag, an opening through which to place an article or food item in the bag, and a fixture through which to evacuate excess air. A user places an article into the enclosure through the opening, seals the opening, and then evacuates the fluid through the fixture. With the chamber thus evacuated, the article contained therein may be significantly compressed, so that it is easier to transport and requires substantially less storage space. For articles of food, storage life can be increased by removing air from the container and by maintaining this reduced oxygen environment.
- Collapsible, 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, which require oxygen to survive and propagate. Moreover, such containers, being impervious to moisture, inhibit the growth of mildew.
- One such container was developed by James T. Cornwell (U.S. Pat. No. 5,203,458). That patent described a disposable, evacuable container for sealing and compressing contaminated surgical garments for ease of storage and transportation prior to disposal.
- Another such container is described in a patent to Akihiro Mori and Ichiro Miyawaki (Japanese Pat. No. 1767786). In that device, the opening through which the stored article is placed requires the application of a heat source, such as a home iron, to form an effective seal.
- United States Patent Application Publication No. 2007/0209326 A1 discloses an evacuable, food storage container having a one way valve for access by an electric vacuum pump.
- U.S. Pat. Application No. 7,178,555 B2 discloses a pressure relief valve for flexible storage containers.
- Commonly owned, United States Patent Publication No. 2006/0131328 A1 discloses evacuable vacuum storage containers having a fitment with a moveable cap and a diaphragm for use with a vacuum pump.
- Vacuum storage containers also include multiple piece containers including a bottom part providing a storage compartment and a top part for releasably attaching to the bottom part and to provide an air tight seal. These containers can be rigid or semi-rigid. The top or bottom part can include a fitment or a one-way valve mechanism for docking to a pump to evacuate air from the container.
