Abstract: The evacuation device is configured to remove air from a container via a one-way valve element attached to the container. The evacuation device includes a motor with a rotating shaft that extends along an axis line. The shaft is operably interconnected to a reciprocating element reciprocally movable within a chamber along a direction parallel to the axis line. Reciprocal motion of the reciprocal element draws air into and exhausts air from the chamber. To facilitate the operable interconnection, the evacuation device includes a cam having a cylindrical sidewall mounted to the rotating shaft. Disposed circumferentially into the cylindrical sidewall is a channel. The evacuation device further includes a yoke connected to the reciprocal element and having a follower element received in the channel. Rotation of the cam causes the follower element to move with respect to the channel, thereby converting rotational motion to linear translation. The evacuation device may also include a pressure adjustment feature.

Abstract: A one-way valve element for use with containers such as flexible storage bags includes an elastomeric or similar material that can elastically expand to expose and at least substantially resiliently recover to cover an aperture through a sidewall of the container. Hence, air from the interior volume of the container can be evacuated through the valve element by, for example, interfacing an evacuation device with the valve element. The valve element can be provided as a single layer structure or a multiple layered structure that is attached to the sidewall of the container over the aperture. In another aspect, a valve element includes a gel-like material retained in a valve body and that can displace to allow air flow across the valve.

Abstract: A closure element is used for closing an opening disposed through the flexible sidewall of a storage bag such as those used to store food items. The storage bags provide an internal volume accessible via the opening. The closure element includes a first fastening strip and an interlocking second closure strip. The first and second fastening strips include complementary, engagable first and second closure profiles. To hermetically seal the internal volume, at least a portion of the first or second fastening strip can include a sealant. The sealant can be a displaceable fluid, fluid-like substance, semi-rigid substance, or wax-like substance such as an oil or a gel. When the closure profiles are engaged, the sealant provides an air tight barrier sealing the internal volume.

Abstract: A storage bag includes first and second sidewalls of flexible, thermoplastic material that overlap and are joined to each other to provide an interior volume for receiving food items. The bag is adapted to be evacuated to help prevent spoliation of the food items. The bag includes a textured portion on an inner surface of at least one sidewall that is comprised of a plurality of pyramid shaped protrusions. To help retain liquids that may be included with the stored food items, the pyramid shaped protrusions are arranged in a substantially offset pattern. The protrusions may delineate on the inner surface substantially planar regions that are comprised of first larger areas and second smaller areas. During evacuation, liquids can pool together in and become retained by the larger areas while air can be directed through the second smaller areas.

Abstract: The storage bag includes an interior volume for containing food items and a one-way valve element through which air from the interior volume can be evacuated. To prevent fluids and juices from the stored food items from contaminating the valve element, a separator defining a chamber is included that sealingly connects the valve element to the interior volume. In the separator, fluids and juices separate from the evacuating air by gravitational separation and are returned to the interior volume. In an embodiment, to facilitate packaging and distribution of multiple storage bags, the separator is adjustable between an expanded position for providing the chamber and a collapsed position substantially eliminating the chamber. In an embodiment, the separator may be comprised of elastically expandable material.
