Abstract
Abstract A closed pressurized container for producing a carbonated beverage of superior quality by providing for contact therein of water and a solid carbonation source. The pressurized container is designed to withstand the pressures and temperatures generated during the preparation of a carbonated beverage from a solid carbonation source. In a preferred embodiment, the container is a rigid receptacle in the shape of a wide mouth bottle adapted to receive a large cap or cover. A perforated basket is mounted inside the cover, and is accessible to water in the bottle when that vessel is turned upside down to an inverted position. A spring loaded, manually operated valve is provided in the cover to permit venting of carbon dioxide from the interior thereof after the water-based mixture within the container has become sufficiently carbonated by absorbing carbon dioxide released by contact of water with the solid carbonation source.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
A pressurizable vessel for the preparation of a carbonated beverage from a water-based liquid and a solid carbonation source, comprising: a. a container having an opening therein providing access to the contents thereof; b. a cover for engaging and sealing the opening of said container, including a basket positioned interiorly of the cover for holding a quantity of a solid carbonation source above the level to which the container is normally filled with the water-based liquid, whereby the container may be filled with water, the basket loaded with a quantity of a solid carbonation source, and the cover applied, and sealed with respect to the container without resulting in contact between the solid carbonation source and water; c. a vent valve provided in said cover to allow automatic and manual venting of excessive carbon dioxide from the interior of the pressurized container prior to disengagement of the cover from the container; and d. means for sealing the container to prevent the pressurized contents of the container from contacting atmosphere.
Claim 2
Dependent Claim
169 words
A pressurizable vessel for the preparation of a carbonated beverage from a water-based liquid and a solid carbonation source, comprising: a. a container having an opening therein providing access to the contents thereof; b. a cover for engaging and sealing the opening of said container, including a basket positioned interiorly of the cover for holding a quantity of a solid carbonation source above the level to which the container is normally filled with the water-based liquid, whereby the container may be filled with water, the basket loaded with a quantity of a solid carbonation source, and the cover applied, and sealed with respect to the container without resulting in contact between the solid carbonation source and water; c. a vent valve provided in said cover to allow automatic and manual venting of excessive carbon dioxide from the interior of the pressurized container prior to disengagement of the cover from the container; and d. means for sealing the container to prevent the pressurized contents of the container from contacting atmosphere.
Claim 3
Dependent Claim
60 words
A pressurizable vessel for the preparation of a carbonated beverage as claimed in claim 1, said basket having openings therein to provide for contact between the solid carbonation source and the water after tilting of the covered container to result in release of carbon dioxide from the solid carbonation source to form carbon dioxide for carbonation of the resultant beverage.
Claim 4
Dependent Claim
61 words
A pressurizable vessel for the preparation of a carbonated beverage as claimed in claim 1, said cover having a flat top to provide a stable base for the covered container when it is inverted and set down, said vent valve having a button for actuation of the valve which is indented with respect to the flat top surface of the cover.
Claim 5
Dependent Claim
43 words
A pressurizable vessel for the preparation of a carbonated beverage as claimed in claim 1, said basket being positioned entirely within the cover of said container and having a cylindrically shaped interior to provide for the containment therein of the solid carbonation source.
Claim 6
Dependent Claim
79 words
A pressurizable vessel for the preparation of a carbonated beverage as claimed in claim 4, the lower surface of said cylindrical basket being formed of a plurality of radially directed, resilient flaps to allow a cylindrical briquette of the solid carbonation source to be placed into the cylindrical basket by resilient deformation of said flaps, with the flaps resiliently returning to form the bottom surface of the cylindrical basket after the briquette of solid carbonation source is inserted therethrough.
Claim 7
Dependent Claim
24 words
A pressurizable vessel for the preparation of a carbonated beverage as claimed in claim 1, said container and cover each being formed of plastic.
Claim 8
Dependent Claim
35 words
A pressurizable vessel for the preparation of a carbonated beverage as claimed in claim 1, said basket being formed as a separate element which is removably and detachably connected to the interior of said cover.
Claim 9
Dependent Claim
27 words
A pressurizable vessel for the preparation of a carbonated beverage as claimed in claim 1, said basket and cover each being threaded for engagement with each other.
Claim 10
Dependent Claim
41 words
A pressurizable vessel for the preparation of a carbonated beverage as claimed in claim 1, said sealing means comprising a cover and a container constructed of a polycarbonate plastic and an annular seal sealingly positioned between said container and said cover.
Claim 11
Dependent Claim
121 words
A pressurizable vessel for the preparation of a carbonated beverage from a water-based liquid and a solid carbonation source, comprising: a. a container having an opening therein providing access to the contents thereof; b. a cover for engaging and sealing the opening of said container; c. a basket positioned interiorly of said opening in the container for holding a quantity of a solid carbonation source, whereby the container may be filled with water, the basket loaded with a quantity of a solid carbonation source, and the cover applied, and sealed with respect, to the container; d. longitudinal vent slots for the venting of excessive carbonation pressure from the interior of the vessel prior to disengagement of the cover from the container.
Claim 12
Dependent Claim
121 words
A pressurizable vessel for the preparation of a carbonated beverage from a water-based liquid and a solid carbonation source, comprising: a. a container having an opening therein providing access to the contents thereof; b. a cover for engaging and sealing the opening of said container; c. a basket positioned interiorly of said opening in the container for holding a quantity of a solid carbonation source, whereby the container may be filled with water, the basket loaded with a quantity of a solid carbonation source, and the cover applied, and sealed with respect, to the container; d. longitudinal vent slots for the venting of excessive carbonation pressure from the interior of the vessel prior to disengagement of the cover from the container.
Claim 13
Dependent Claim
38 words
A pressurizable vessel for the preparation of a carbonated beverage as claimed in claim 10, said basket holding a quantity of solid carbonation source above the level to which the container is normally filled with a water-based liquid.
