Fermentation container

Claim 2

A fermentation container, comprising means for receiving a fermentable liquid and for storing said liquid during at least a portion of the fermentation of said liquid, said receiving and storing means comprising a nonporous plastic bag having an opening, a closure receiving structure secured to the bag communicating with said opening, a closure in sealing engagement with the structure and removable from the structure and diaphragm means disposed on said closure for enabling the escape of fermentation gases from said bag, said diaphragm means having a Gurley porosity in the range of 2 to 120 seconds and for preventing gas and moisture from entering said bag.

Claim 3

A fermentation container as defined in claim 1 in which the closure receiving structure and the closure are shaped for detachable sealing engagement.

Claim 4

A fermentation container as defined in claim 1 in which the closure receiving structure has an outside surface slightly larger than an inside surface of the closure so that the closure can be snapped into sealing engagement with the closure receiving structure.

Claim 5

A fermentation container as defined in claim 1 wherein the diaphragm is a spun bonded polyolefin having a Gurley porosity of 2 to 120 seconds.

Claim 6

A fermentation container as defined in claim 1 wherein the diaphragm is paper having a Gurley porosity of 2 to 120 seconds.

Claim 7

A fermentation container as defined in claim 5 wherein the paper is glassine.

Claim 8

A fermentation container as defined in claim 1 wherein the plastic bag is made from a material selected from the group consisting of polyolefin, ethylene-vinyl acetate copolymer, polyurethane, laminated polyethylene and polyvinylidene chloride, and a coextrusion of polyethylene and polyvinylidene chloride.

Claim 9

A fermentation container, comprising means for receiving a fermentable liquid and for storing said liquid during at least a portion of the fermentation of said liquid, said receiving and storing means comprising a nonporous plastic bag having an opening and diaphragm means disposed over said opening in said bag for enabling the escape of fermentation gases from said bag and for preventing bacteria organisms, spores, or any other contaminant from entering said bag said means having a Gurley porosity in the range of 2 to 120 seconds and disposed such that all gases leaving said bag during fermentation must pass through said means.

Claim 10

A fermentation container, comprising means for receiving a fermentable liquid and for storing said liquid during at least a portion of the fermentation of said liquid, said receiving and storing means comprising a nonporous plastic bag having an opening and diaphragm means disposed over said opening in said bag for enabling the escape of fermentation gases from said bag and for preventing bacteria organisms, spores, or any other contaminant from entering said bag said means having a Gurley porosity in the range of 2 to 120 seconds and disposed such that all gases leaving said bag during fermentation must pass through said means.

Claim 11

A fermentation container as defined in claim 8 which further includes a closure receiving structure sealed to said bag, an inside surface of the closure receiving structure defining an opening in the bag; and a closure in sealing engagement with the closure receiving structure and removable from said closure receiving structure, said closure having said diaphragm sealed to its inside surface.

Claim 12

A fermentation container, comprising means for receiving a fermentable liquid and for storing said liquid during at least a portion of the fermentation of said liquid, said receiving and storing means comprising a nonporous plastic bag having a top surface and a bottom surface; a first opening in said top surface; diaphragm means disposed over said first opening for enabling the escape of fermentation gases from said bag and for preventing bacteria organisms, spores, or any other contaminant from entering said bag, said means having a Gurley porosity in the range of 2 to 120 seconds and disposed such that all gases leaving said bag during fermentation must pass through said means; a second opening in said top surface; means disposed over said second opening for providing an inlet for a liquid into said container; an opening in said bottom surface; and means disposed over said bottom surface opening for providing an outlet for said liquid from said container.

Claim 13

A fermentation container, comprising means for receiving a fermentable liquid and for storing said liquid during at least a portion of the fermentation of said liquid, said receiving and storing means comprising a nonporous plastic bag having a top surface and a bottom surface; a first opening in said top surface; diaphragm means disposed over said first opening for enabling the escape of fermentation gases from said bag and for preventing bacteria organisms, spores, or any other contaminant from entering said bag, said means having a Gurley porosity in the range of 2 to 120 seconds and disposed such that all gases leaving said bag during fermentation must pass through said means; a second opening in said top surface; means disposed over said second opening for providing an inlet for a liquid into said container; an opening in said bottom surface; and means disposed over said bottom surface opening for providing an outlet for said liquid from said container.

Claim 14

A container as defined in claim 10 wherein said second opening is disposed near one end of the top surface of said container and wherein said third opening is disposed near the same end of the bottom surface of said container.

Claim 15

A container as defined in claim 11 further including means for allowing and stopping the flow of liquid from said container.
