The disclosure provides a vacuum packaging product. The vacuum packaging product includes an outer packaging member and a cartridge configured for use in an electronic cigarette. The cartridge is filled with an aerosol-forming substrate. The cartridge is packed and hermetically sealed in the outer packaging member in a vacuum state. Since the outer packaging member is in a vacuum state, a pressure difference exists between the inside and the outside of the outer packaging member due to the vacuum state of the outer packaging member, and the outer packaging member is contracted, so as to better seal the cartridge that has been filled with the aerosol-forming substrate, and to avoid leakage caused by possible high temperature, high pressure or negative pressure during transportation.

To provide an inorganic solid material that has a hydrogen sulfide sustained releasability at ordinary temperature in the air atmosphere and is capable of being handled safely and a method for producing the same, and a method for generating hydrogen sulfide using the material. A layered double hydroxide having HS- and/or Sk2- (wherein k represents a positive integer) intercalated among layers (sulfide ion-containing LDH) is produced, and the sulfide ion-containing LDH is hermetically housed in a packaging material to provide a package. In generating hydrogen sulfide, the packaging material of the package is opened, and the sulfide ion-containing LDH is exposed to the air atmosphere to sustainably release hydrogen sulfide.

A container includes a multilayered composite film combination forming a bag defining a product fill opening. The multilayered composite film combination includes first and second polymer film inner and outer layers each having vacuum holding properties, and a third polymer film disposed between the first and second polymer films. The third polymer film has oxygen barrier properties. Product is packed into the container by coupling a fill spout of the container with a fill tube of a product filling apparatus, and oxygen is drawn from an inner cavity of the container. Fluidized product entrained in nitrogen and/or carbon dioxide gas is flowed through the fill spout of the container, and nitrogen is added into the inner cavity through the fill spout of the container. The fill spout of the container is sealed while a negative pressure is drawn within the inner cavity thereby immobilizing the product within the container.

A vacuum storage bag assembly includes a zipper bag and a vacuum valve. An opening is formed on the zipper bag. The vacuum valve is connected to the zipper bag. The vacuum valve includes a valve seat, a filtrating component and a check valve. The valve seat is disposed on the zipper bag. The valve seat includes a connecting port and a communication channel communicated with the connecting port and with interior of the zipper bag via the opening, and the connecting port is configured to be connected to a vacuum source. The filtrating component is disposed on an upstream portion of the communication channel. The check valve is disposed on a downstream portion of the communication channel and allows fluid to flow from the interior of the zipper bag, through the filtrating component, and to flow out of the connecting port.

A selectively sealable evacuable storage bag comprises a first side comprising a flexible waterproof bag material having a first peripheral shape, a thickness, a first inner surface and a first outer surface; an opposed second side of the bag material comprising a mirror image of the first side in corresponding engagement with the first side; a waterproof weld joining the first side to the second side and defining an opening and a storage chamber extending between them, the opening configured to receive an article; a valve disposed on the first side or the second side, the valve disposed in a conduit attached to respective side and extending from a conduit opening to an outlet opening; and a selectively openable and closable seal disposed proximate the opening and providing a watertight, dust tight, and airtight seal in a closed condition, wherein in the closed condition the storage chamber is evacuable.

A system and method for providing a screen protector to a portable handheld electronic device or cell phone with a user facing surface comprises a mold having an outer surface matching a user facing surface. A stack of layers including the screen protector is disposed over the outer surface of the mold. A vacuum bag receives and surrounds the stack of layers disposed over the mold. The vacuum bag is sealed and evacuated of air. The screen protector is heated and/or cured while in the vacuum bag to shape the screen protector over the mold to have curved lateral edges matching curved lateral edges of the outer surface of the mold and the user facing surface of the display screen of the cell phone. The vacuum bag maintains the curved lateral edges of the screen protector against the curved lateral edges of the outer surface of the mold.

A pre-packaged paint sample includes a sealed package, paint sealed within the package, and a new paint applicator sealed within the sealed package. For use, the package is shook to apply the paint to the paint applicator. The sealed package is opened, and the paint applicator is removed from the package. The paint applicator and used to apply the relatively small amount of the paint t. The pre-packaged paint sample can be useful in applications where only a small amount of paint is needed such as, for example but not limited to, paint sampling, paint touch up, and the like.

A vacuum bag is disclosed. The vacuum bag may include a body. The body may include a plastic layer and a fabric layer. The plastic layer and the fabric layer may be welded together on at least one portion of the body. The vacuum bag may further include a seal bar and a valve.
