A device comprises a bag comprising a non-porous material. The bag has a plurality of edges. The device has at least one glove with an open end. The open end has a perimeter. The perimeter is integrally joined to the non-porous material along one of the plurality of edges. The at least one glove is positionable inside the bag, with the open end of the glove facing out of the bag. The bag has a closure capable of forming a seal when the closure is closed.

A multifunctional valve features an injection function, a vacuuming function, a devacuuming function with fast and slow mode, and a pressure regulating function. The valve can be implemented on any sealingly closed container having a removable lid or a bag having a resealable zipper or any other similar sealable feature. The valve also features a tethered plug with a latch system to secure it in place to additionally provide sealing. The valve is incorporated into a container with a removable lid for microwave pressure cooking. The same valve is incorporated into a plug to close an opening on a barrel.

The present disclosure provides a flexible container. In an embodiment, a flexible container is provided and includes a first multilayer film and a second multilayer film. Each multilayer film has an inner seal layer. The multilayer films are arranged such that the seal layers oppose each other and the second multilayer film is superimposed on the first multilayer film. The multilayer films are sealed along a common peripheral edge. An orifice is present in one of the multilayer films. The flexible container includes an extendable spout extending through the orifice. The extendable spout has a flange sealed to the inner seal layer of the multilayer film at the orifice. The extendable spout is composed of, or is otherwise formed from, an ethylene/-olefin multi-block copolymer.

A multifunctional valve features a pumping function and a vacuuming function. The valve can be implemented in any closed container having a removable lid or a bag having a resealable zipper or any other similar sealable feature. The valve also features a tethered plug to additionally provide sealing. The valve incorporates a spacer or washer when used in thin walls to provide support. When the valve is used with a bag, the spacer or washer incorporates footing so that the valve does not collapse on its own when the valve is used in conjunction with a vacuum pump or a gas pump.

A resealable bag having an integrated manual pump is provided. The resealable bag includes: a front wall and a back wall together defining a cavity, a sealable closure configured to seal an opening to the cavity, and a manual pump positioned within an aperture in the front wall, wherein the manual pump includes a frame around a perimeter of the aperture, a pump ball positioned within the frame, and an ingress valve and an egress valve in fluid communication with an interior of the pump ball. Air is removed from the bag by depressing the pump ball, which forces air through the egress valve from the interior of the pump ball to an exterior of the bag. The pump ball refills with air between depressions due to air from the bag cavity entering the pump ball through the ingress valve disposed on a cavity-facing surface of the pump ball.
