Pressure regulators for beverage dispensers of the type using a high pressure gas cartridge such a CO2 cartridge. The regulators provide a simple, low cost, easily assembled and reliable regulator of particularly small size, facilitated in part by the fact that the invention allows the use of a diaphragm of a particularly small size without necessitating the use of expensive and bulky diaphragm clamps, such as threaded clamps, yet is able to provide a more than adequate seal at both the inner and outer portions of the diaphragm.

1. A pressure regulator comprising: a regulator body having a first threaded region for engaging cooperatively disposed threads on a CO2 cartridge holder, and having a first opening coaxial with the first threaded region;the regulator body having a second opening intersecting the first opening and having an axis substantially perpendicular to the first opening, the second opening being disposed to deliver CO2 at the regulated pressure to a beverage container when fastened to a beverage container;a regulator member within the second opening;an orifice member in the first opening and projecting between two sides of the regulator member to define an orifice facing the delivery side of the second opening;the regulator member having a first end region having an orifice closure member therein adjacent the orifice, and a second end region, the first and second end regions being integrally coupled by the two sides of the regulator member;the second end region defining an outer surface between first and second flange regions;a flexible diaphragm having an inner surface stretched over, restrained from movement and sealing with respect to the outer surface of the second end region of the regulator member between the first and second flanges, and having a outward extending flexible region;a retainer snapped into an end of the second opening to lock and seal an outer edge region of the outward extending flexible region to the regulator body; and,a spring disposed between the retainer and the second end region of the regulator member to push the second end region toward the orifice member. 2. A pressure regulator comprising: a CO2 cartridge holder;a regulator body having a first threaded region for screwing onto a beverage container, a second threaded region for engaging cooperatively disposed threads on a CO2 cartridge holder, and a first opening coaxial with the second threaded region;the regulator body and CO2 cartridge holder being configured to prevent unscrewing of the CO2 cartridge holder from the regulator body;the regulator body having a second opening intersecting the first opening and having an axis substantially perpendicular to the first opening, the second opening being disposed to deliver CO2 at the regulated pressure to the beverage container when screwed onto the beverage container;a regulator member within the second opening;an orifice member in the first opening and projecting between two sides of the regulator member to define an orifice facing the delivery side of the second opening;the regulator member having a first end region having an orifice closure member therein adjacent the orifice and a second end region, the first and second end regions being integrally coupled by the two sides of the regulator member;the second end region defining an outer surface between first and second flange regions;a flexible diaphragm having an inner surface stretched over, retained by and sealing with respect to the outer surface of the second end region of the regulator member between the first and second flanges, and having a outward extending flexible region;a retainer snapped into an end of the second opening to lock and seal an outer edge region of the outward extending flexible region to the regulator body; and,a spring disposed between the retainer and the second end region of the regulator member to push the second end region toward the orifice member. 3. A pressure regulator comprising: a CO2 cartridge holder;a regulator body having a first threaded region for screwing onto the beverage container, a second threaded region for engaging cooperatively disposed threads on a CO2 cartridge holder, and a first opening coaxial with the second threaded region;the regulator body and CO2 cartridge holder being configured to prevent unscrewing of the CO2 cartridge holder from the regulator body;the regulator body having a second opening intersecting the first opening and having an axis substantially perpendicular to the first opening, the second opening being disposed to deliver CO2 at the regulated pressure to the beverage container when screwed onto the beverage container;a regulator member within the second opening;an orifice member in the first opening and projecting between two sides of the regulator member to define an orifice facing the delivery side of the second opening;the regulator member having a first end region having an orifice closure member therein adjacent the orifice and a second end region, the first and second end regions being integrally coupled by the two sides of the regulator member;the second end region defining an outer surface between first and second flange regions;a flexible diaphragm having an inner surface stretched over and sealing with respect to the outer surface of the second end region of the regulator member between the first and second flanges, and having a outward extending flexible region;a retainer locking the outer edge region of the outward extending flexible region to the regulator body;a spring disposed to push the second end region toward the orifice member;the regulator body and CO2 cartridge holder are configured to prevent unscrewing the CO2 cartridge holder from the regulator body by a ratchet surface molded into an inner surface of the regulator body adjacent the second threaded region, and a plurality of elastic pawls molded into the cartridge holder;the retainer having a plurality of fingers and is snapped into the end of the second opening by the fingers snapping into openings molded in the regulator body. 4. A pressure regulator comprising: a CO2 cartridge holder;a regulator body having a first threaded region for screwing onto a beverage container, a second threaded region for engaging cooperatively disposed threads on a CO2 cartridge holder, and a first opening coaxial with the second threaded region;the regulator body and CO2 cartridge holder being configured to prevent unscrewing of the CO2 cartridge holder from the regulator body;the regulator body having a second opening intersecting the first opening and having an axis substantially perpendicular to the first opening, the second opening being disposed to deliver CO2 at the regulated pressure to the beverage container when screwed onto the beverage container;a regulator member within the second opening;an orifice member in the first opening and projecting between two sides of the regulator member to define an orifice facing the delivery side of the second opening;the regulator member having a first end region having an orifice closure member therein adjacent the orifice and a second end region, the first and second end regions being integrally coupled by the two sides of the regulator member;the second end region defining an outer surface between first and second flange regions;a flexible diaphragm having an inner surface stretched over, retained by and sealing with respect to the outer surface of the second end region of the regulator member between the first and second flanges, and having a outward extending flexible region;a retainer snapped into an end of the second opening to lock and seal an outer edge region of the outward extending flexible region to the regulator body; and,a spring disposed between the retainer and the second end region of the regulator member to push the second end region toward the orifice member;wherein the retainer includes a plurality of fingers and is snapped into the end of the second opening by the fingers snapping into openings molded in the regulator body.
