A compression bag includes longitudinally continuous sheets continuously supplied in a longitudinal direction to lie one upon another, and adhered at predetermined spots to form an article containing portion having a space for an article and an air passageway having a space continuing to the space of the article containing portion. The sheets include a frontal sheet, a rear sheet which is equal to the frontal sheet in breadth (i.e., the transverse side dimension of the sheets), at least one valve body sheet disposed between the frontal and rear sheets and made smaller than the front and rear sheets in breadth, and base members disposed between at least one of the frontal and rear sheets and the valve body sheet and made smaller than the valve body sheet in breadth.

A storage system comprising: an evacuable and reclosable bag comprising a wall made of a flexible material and a one-way valve attached to said wall of said bag; a container having walls made of a material less flexible than the flexible material; and an attachment device that attaches the bag to the container such that at least a portion of the bag resides within the container. To use this storage system, compressible articles are placed inside the evacuable bag. Then the bag is hermetically sealed and evacuated. During evacuation, the shape of the compressible articles inside the bag conform to the shape of the container interior volume. In one embodiment, when the bag with compressed articles is removed from the container, its shape facilitates stacking. In another embodiment, the storage bag with compressed articles remains inside the container.

A pouch has an elongate closure mechanism adapted to provide vacuum retention within an interior of the pouch over an extended period of time when sealed. The closure mechanism includes a first pair of interlocking members that resealably mate together, a second pair of interlocking members that resealably mate together, and a pair of sealing members that form an air tight seal separate from the interlocking members disposed between the first and second pairs of interlocking members. The closure members are connected with opposing panels of the pouch in a manner designed to provide differential opening and closing forces. The pouch may include a check valve and air evacuation channels to aid in evacuating air from the interior.

An application for a container with integrated vacuum pump including a non-porous sealable enclosure with walls and an aperture in a first of the walls. A vacuum pump is affixed to the first of the walls of the non-porous sealable enclosure. The vacuum pump has an inflow port that is interfaced to the aperture so that the vacuum pump is adapted to evacuate air from the non-porous sealable enclosure through the aperture.

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. Storage bags of this type 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, 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.

The present invention provides a one way valve having a valve body, a wall, a fluid inlet, and a fluid outlet. The valve has a plunger which is moveable with respect to the valve body from a first position to a second position. The valve also has a diaphragm positioned in the valve body for movement between a third position and a fourth position when the plunger is in the first position. When the diaphragm is in the third position the fluid outlet is closed and when the diaphragm is in the fourth position the fluid outlet is open.

An improved wine bottle closure and vacuum pump apparatus is disclosed. The apparatus provides an improved bulb structure to be used for pumping and storage purposes, the bulb remaining with a closure plug even after pumping is completed and the wine is to be stored for later consumption. The bulb structure can be collapsed in two different positions including a first position that maintains overall height of the bulb structure and a second position that enables the bulb structure to be shortened in height as an optional feature. The bulb structure provides an enlarged central section that is much larger in diameter than the lower end portion. The lower end portion provides a closure plug for fitting the opening of a wine bottle.

A vacuum valve device is used with a bag and has a base and a clip. The base has a tube, a clipping flange and a valve. The tube mounted through a sheet of the bag and has a central hole and at least one outlet hole. The clipping flange is formed on the tube. The valve is mounted slidably in the tube and selectively seal the at least one outlet hole. The clip is mounted detachably around the tube of the base and cooperates with the clipping flange to hermetically clip the sheet of the bag. The vacuum valve device may be reused, is economical and marketable.

A one-way valve allows air to be drawn from a collapsible, flexible, airtight bag using a vacuum source. When the vacuum source is removed, the one-way valve prevents air from re-entering the bag. The valve assembly comprises a base, a valve element supported by the base, and a cap fitted onto an end of the base that is disposed in the exterior of the bag. The base comprises a flange that is disposed in the interior of the bag and is joined to a peripheral area surrounding a hole in one wall of the bag. One surface of the flange has a series of concentric heat-concentrating circular beads for speeding up the conduction heat sealing operation by which the valve assembly is attached to the bag. The valve cap is provided with a circular wall that presses the diaphragm of the valve element against a circular bead on an annular seat formed on the base for supporting the valve element.

A closure device (11) for a bottle comprising an attachment means (14) which attaches to the neck (21) of a bottle and comprises a sleeve portion (33) having an inner surface (20) with a thread configured to engage with an external thread on the neck of the bottle and a main body (25) having a pump portion with a pump (26), whereby the device is able to attach to the bottle by screwing the attachment means onto the bottle neck to enable the pump to be used to extract air from the bottle. In another embodiment instead of a pump, the main body may include a pour portion to assist in pouring of contents of the bottle including a cover portion for covering the opening to the mouth of the bottle.
