Abstract: Airtight compressible storage containers (e.g., pouches) having one-way valves in the form of respective collapsible channels that run along and adjacent to respective pouch side seals. Each collapsible channel comprises unsealed sections of web material that span the space between a respective side seal and a respective interior seal. Each collapsible channel communicates with a respective air inlet located in the interior volume of the pouch and a respective air outlet located on a periphery of the pouch. When the contents of the pouch are compressed by a user pushing down on pouch, air from the storage chamber containing the compressible contents can be forced into the air inlet, through the open channel and out the air outlet until the desired amount of air has been removed from the pouch.

Abstract: 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 valve base attached to a bag wall and having an opening, a cap base coupled to the valve base, a flapper held in place by the valve base and cap base, and a cap connected to the cap base by a living hinge. When the cap is snapped onto the cap base after bag evacuation, the cap maintains the flapper in a position so that the opening in the valve base stays closed, preventing the admission of ambient air into the evacuated bag.

Abstract: 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.

Abstract: Opening and secure-closing system for doors comprising two doors (1,2) for accessing the interior of a chamber, which open towards the outside being hinged around two hinging axes (19,20), both doors (1,2) comprising a set of bolts (17,18) and the opening and closing system comprising additional means of opening/closing operation (26) and an overpressure door (3) located in one of the doors (1,2) which opens towards the outside, in such a way that the means of opening/closing operation (26) comprise a blocking bar (4), a blocking fitting (7) and means of retention (10) between the two doors (1,2) in order to provide a controlled and sequential opening/closing operation of the chamber, and the overpressure door (3) is opened automatically in the event of emergency due to overpressure, and it also participates in the controlled and sequential opening/closing operation of the chamber.

Abstract: Support system suitable for sustaining an auxiliary power unit of an aircraft to a fixed structure (2) belonging to a compartment of the auxiliary power unit (6) of the aircraft. The support system is made in a high mechanical strength material and with high resistance to ignition, and comprises three fittings (3, 4, 5) two of which are frusto-conical and one with a substantially cylindrical. Fittings (3, 4, 5) being able to be hollow and being able to comprise an array of lateral ribs. Each one of them presenting a first end (7) comprising means of attachment of the support system (8) to the fixed structure (2) and a second end (9) comprising means of securing of the support system (8) which are joined to the auxiliary power unit (1) in the periphery of the extension of said auxiliary power unit (1).

Abstract: Methods for manufacturing airtight storage containers (e.g., bags or pouches) made from thermoplastic web material and having heat-sealed margins along a perimeter. To ensure that the storage containers are airtight, an unheated rib is pressed along each heat seal while the web material in the region of each heat seal is still in a softened and pliable state. As a result of the pressure applied, the rib deforms the contacted portion of the heat-sealed web material, leaving an indentation upon cooling of the web material that serves as an air leakage barrier. This air leakage barrier ensures that any air leakage pathway across the heat seal region is closed.

Abstract: A system comprising: a tote bag comprising a container having an opening and means for closing the opening, wherein the container comprises first and second rigid or semi-rigid side walls and a connecting wall made of flexible fabric material; and a resealable evacuable bag placed inside and freely removable from the tote bag via the opening. The resealable evacuable bag comprises: a receptacle having an interior volume and a mouth that allows communication between an exterior and the interior volume, the receptacle comprising flexible front and rear walls and a flexible gusseted bottom; a resealable closure installed in the mouth; a one-way valve mounted to a hole in the front wall; and a rigid or semi-rigid board loosely disposed inside and freely removable from the receptacle and in contact with the gusseted bottom.

Abstract: A hanging storage system comprising a resealable evacuable bag and a hanging device attached to the bag. The hanging device is designed to attach to a portion of the bag in a manner such that a vacuum inside the evacuated bag can be maintained while the bag is hanging, e.g., in a closet. More specifically, the hanging device comprises first and second parts that couple together, the first part being disposed inside the bag and the second part being disposed outside the bag, with a portion of a thin flexible bag wall being disposed between the coupled first and second parts.
