A storage bag for particular use with home based vacuum heat sealing devices includes adjacent compartments separated by a frangible seam. A first compartment may store substantially dry foodstuffs such as meat, and/or crunchy items. A second adjacent compartment may store a liquid marinade, sauce of similar flavoring. The openings for each compartment may be provided on opposite edges of the bag so that each compartment may be independently heat sealed using a vacuum sealing device. The first compartment may additionally be evacuated. The sealed bag may be stored until ready for consumption, at which time the internal frangible seam may be broken to allow mixing of the two compartments.

A storage bag for particular use with home based vacuum heat sealing devices includes nested bags. An outer bag may store substantially dry foodstuffs such as meat, and/or crunchy items. A smaller bag, pouch or sachet may store a liquid marinade, sauce or similar flavoring. The smaller bag may be sealed and then sealed within the outer bag which be vacuum sealed. Channels may be embossed into the bag layers of the outer bag to facilitate evacuation of the outer bag by the vacuum sealing device prior to heat sealing. The smaller inner bag may include a frangible outer seam that can be manipulated through the outer bag to cause the seam to rupture, thereby allowing the contents of the inner bag to mix with the contents of the outer bag, e.g. to cause a meat product to marinate prior to consumption.

A dual fluid cartridge assembly includes a cartridge, a flange, and a piston tube. The cartridge defines a channel and includes an flange. The flange defines a cavity that extends from a cavity opening to a cavity base. The cavity opening is positioned within the channel of the cartridge, and the cavity base is positioned external to the cartridge. The piston tube has an extended end, and is positioned at least partially within the channel. The extended end is positioned within the cavity.

A machine produces foam-in-bag from foam precursors mixed within the bag. The machine comprises a base and a shell. The base and shell are moveable relative each other between a base/shell disengaged position and a base/shell engaged position. In the base/shell engaged position, the base and shell divide the bag so that a mixing chamber is isolated from the remainder portion of the bag. First and second nozzles inject foam precursors into the mixing chamber. A mixer engages the mixing chamber to provide mixing energy to facilitate the foam reaction.

A method of making an upwardly open container having a base wall, an upright perimeter wall, and an upright internal wall between one part of the perimeter wall and another part of the perimeter wall, the perimeter wall and the internal wall forming first and second compartments within the container, wherein the method comprises injecting a molten water-soluble polymer into a mold cavity between cooperating male and female mold parts; wherein there are independently movable first and second male parts separated by a gap in which the internal wall is formed, and wherein the first and second male parts correspond to the first and second compartments of the container to be formed.

A device for facilitating a chemical reaction that includes an upper member, a lower member, and a dissolvable member disposed between them such that upper and lower chambers are formed having substantially equal volumes. The upper chamber receives a dry sodium chlorite and the lower chamber receives a dry acid mixture. The upper and lower members are joined, thereby sealing the upper and lower chambers and enabling the joined upper and lower members to be disposed in water such that said lower member engages the water first. The joined upper and lower members swell with absorbed water to engage the dry sodium chlorite and the dry acid mixture to form slurries to dissolve the dissolvable member to allow the slurries to react to generate chlorine dioxide gas that passes through the upper and lower members and into a space to be disinfected and/or deodorized.

A device for facilitating a chemical reaction while submerged in a liquid catalyst includes an upper member, a lower member, and a dissolvable member disposed between and ultimately enclosed by said upper and lower members such that upper and lower chambers are formed having substantially equal volumes. The upper chamber may receive a dry sodium chlorite and the lower chamber may receive a dry acid mixture. In order to keep the device submerged in the liquid catalyst, an inert ballast may also be added to the upper and/or lower chamber, such as glass shards.
