US Patent:

6408872, Jun 25, 2002

Filed:

May 12, 1999

Appl. No.:

09/310468

Inventors:

Janet L. Skeens - San Carlos CA
Gerald W. Sweeney - La Jolla CA

Assignee:

New West Products, Inc. - San Diego CA

International Classification:

F16K 1514

US Classification:

13751215, 137550, 137854, 141 65, 2065248, 383103

Abstract:

A one-way valve allows air to be drawn from a collapsible, flexible, air-tight bag using a vacuum source. When the vacuum source is removed, the one-way valve prevents air from re-entering the bag. A filter is placed on the valve body to prevent small particles from the bag from clogging the valve or the vacuum source.

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

F16K 1514

US Classification:

137845, 137 1, 137 1518, 137843, 2511491, 2065248, 99472

Abstract:

A valve assembly mounted in a resealable/reclosable storage bag. The valve assembly includes a base and a valve element. The valve element includes a stem with a convex cap attached at one end and a valve gate attached at the opposite end. The stem extends into a hole in the base. The resilient quality of the cap, acting against the top of the base, holds the gate against the bottom of the base, thereby forming a seal between the gate and the base that is strong enough to preserve the vacuum inside the bag. A cavity extends into the stem from the cap end. A hole in the stem runs from the cavity to outside the stem. When the stem is pressed down, a vacuum source may draw air between the gate and the base, through the hole in the stem, into the cavity, and subsequently outside the bag.

US Classification:

383/100000, 206/524800, 383/044000, 493/213000

Abstract:

A flexible, evacuable storage bag has a storage portion, an airtight seal, and a one-way valve. The valve includes a strip sandwiched between top and bottom sheets used to make the bag. The strip is bonded along the edges to the top and bottom sheets so as to form passageways extending from the storage portion to outside the bag.
