A mechanism for carbonating a liquid in a bottle that has a neck with outer threads includes a source of pressurized carbon dioxide, a dispenser to controllably release the carbon dioxide through an orifice in a pointed component. A bottle cap has a thickness and has a hole in it. A check valve installed in the hole includes an elastomeric plug having a high pressure side and a low pressure side joined by a stem. A passageway open at the low pressure side extends through the low pressure side, the stem and into the high pressure side, terminating within a shank in the high pressure side and defines a shank sidewall laterally of the passageway. At least one puncture is made through the shank sidewall to the passageway.

1. A check valve for installation in a hole in a body having a defined thickness comprising an elastomeric plug having a high pressure side and a low pressure side joined by a stem,a passageway open at the low pressure side and extending through the low pressure side, through the stem and into the high pressure side, terminating within a shank in the high pressure side and defining a shank sidewall laterally of the passageway, andat least one puncture through the shank sidewall to the passageway,whereby when the plug is installed with the stem in the hole of the body and the low pressure side on one side of the hole and the high pressure side on an opposite side of the hole, a high pressure source can be introduced into the passageway from the low pressure side, high pressure fluid can be released into the passageway from the high pressure source, causing passageway distention and enlarging the puncture to allow high pressure fluid to flow through the puncture, and when the high pressure source is removed, the passageway returns to an undistended shape, closing the puncture and preventing flow of pressurized fluid from the high pressure side to the low pressure side. 2. A check valve as claimed in claim 1 wherein the low pressure side is shaped like a mushroom cap attached to the stem. 3. A check valve as claimed in claim 1 wherein the low pressure side has an outer flange and the high pressure side has an inner flange and the inner and outer flanges are separated by a distance smaller than the thickness of the body having the hole so that the stem between the inner and outer flanges remains in a state of tension in the direction parallel with the passageway when installed, pulling the inner and outer flanges into contact with the body, facilitating the integrity of the seal between the plug and the body. 4. A check valve as claimed in claim 1 wherein the low pressure side has an outer flange and the high pressure side has an inner flange and the inner and outer flanges are separated by the stem, the stem having a relaxed diameter greater than the diameter of the hole in the body so that the stem between the inner and outer flanges remains in a state of transverse compression in the hole when installed, facilitating the integrity of the seal between the plug and the body. 5. A check valve as claimed in claim 1 wherein the punctures are narrow slits in the sidewall of the shank and aligned to the passageway, allowing the narrow slits to open up as the high pressure side is distended, lowering resistance to flow when dispensing pressurized liquids or gasses through the valve. 6. A check valve as claimed in claim 5 wherein there are at least two slits opposed to one another across the passageway. 7. A check valve as claimed in claim 1 wherein the low pressure side forms an outer flange and the high pressure side forms an inner flange and the inner and outer flanges are joined by the stem, the stem being curved as it joins the inner and outer flanges. 8. A check valve as claimed in claim 1 wherein the plug has a circular cross section. 9. A check valve as claimed in claim 1 wherein the shank of the high pressure side extends below the passageway's termination sufficiently far to form a handle to allow pulling of the plug through the hole in the body. 10. A check valve as claimed in claim 1 wherein the shank in the high pressure side extends below the passageway's termination at least twice as far as the passageway extends into the high pressure side to form a handle to allow the plug to be pulled through the hole in the body. 11. A check valve as claimed in claim 1 wherein the elastomer of the plug has a hardness on the Shore A scale of 43 (ten seconds on the ASTM D2240 test) and ultimate tensile strength in the range from 750 to 800 psi. 12. A check valve as claimed in claim 1 wherein the stem of the plug remains in a state of tension when installed, causing a flange on the high pressure side to seat against, in contact with, and tightly sealed to the body surrounding the mounting hole. 13. A check valve for installation in a hole in a body having a defined thickness comprising an elastomeric plug having a high pressure side and a low pressure side joined by a stem having a length not greater than the defined thickness,the high pressure side having a flange connected to the stem and tapering away from the flange to an elongated shank having a bottom,a passageway open at the low pressure side and extending through plug, through the stem and into the high pressure side, terminating within the shank in the high pressure side and defining a shank sidewall, andat least one puncture through the shank sidewall to the passageway,so the elongated, tapered shank can be inserted at least partially through the hole in the body and the tapered shank can be pulled, causing the elastomeric plug to elongate and thin under tension so that the flange of the high pressure side can pass through the hole until the stem is resident in the hole with the low pressure side not passing through the hole, the flange of the high pressure side forming a seal to close the hole in the body,whereby a high pressure source can be introduced into the passageway, high pressure fluid can be released into the passageway, causing passageway distention and enlarging the puncture to allow high pressure fluid to flow through the puncture, and when the high pressure source is removed, the passageway returns to undistended shape, closing the puncture and preventing flow of pressurized fluid from the high pressure side to the low pressure side. 14. A mechanism for carbonating a liquid in a bottle that has a neck with outer threads comprising a source of pressurized carbon dioxide,a dispenser to release carbon dioxide from the source of pressurized carbon dioxide in a controlled fashion through an orifice in a pointed component of the dispenser,a bottle cap having a round cap end and a peripheral skirt that has internal threads to match the outer threads on the bottle neck, the round cap end having a thickness and having a hole in it, anda check valve installed in the hole in round end cap including an elastomeric plug having a high pressure side and a low pressure side joined by a stem,a passageway open at the low pressure side and extending through the low pressure side, through the stem and into the high pressure side, terminating within a shank in the high pressure side and defining a shank sidewall laterally of the passageway, andat least one puncture through the shank sidewall to the passageway,whereby when the plug is installed with the stem in the hole of the body and the low pressure side on one side of the hole and the high pressure side on an opposite side of the hole, a high pressure source can be introduced into the passageway from the low pressure side, high pressure fluid can be released into the passageway from the high pressure source, causing passageway distention and enlarging the puncture to allow high pressure fluid to flow through the puncture, and when the high pressure source is removed, the passageway returns to an undistended shape, closing the puncture and preventing flow of pressurized fluid from the high pressure side to the low pressure side.
