System and Method for Preserving Wine and Other Perishable Substances

摘要

A volumetric displacement preservation system for preserving a volume of flowable substance in a vessel. A fluid exchange structure has a stopper, a head portion, and a fluid exchange valve with a first condition where fluid inlet and exhaust pathways in the fluid exchange structure are simultaneously closed and a second condition where the fluid inlet and exhaust pathways are simultaneously opened by conduit joining portions in the fluid exchange valve. A chamber retains a volume of preservative gas and is connected to the fluid inlet pathway externally to the vessel. The preservative gas can be supplied from the chamber into the vessel through the fluid inlet pathway as liquid is exhausted through the fluid exhaust pathway. The chamber can be replenished from preservative gas displaced from the vessel in a reverse volumetric displacement process or from preservative gas supplied by a preservative gas production canister.

1. A volumetric displacement preservation system for preserving a volume of flowable substance in an open inner volume of a vessel, the volumetric displacement preservation system comprising:
a fluid exchange structure with a stopper for creating a sealing engagement with the vessel; a fluid exhaust pathway in the fluid exchange structure with a first end to be in fluidic communication with the open inner volume of the vessel and a second end to be in fluidic communication exterior to the vessel when the stopper is engaged with the vessel wherein the fluid exhaust pathway has an open condition where fluid can pass through the fluid exhaust pathway and a closed condition where fluid substantially cannot pass through the fluid exhaust pathway; a fluid inlet pathway in the fluid exchange structure with a first end to be in fluidic communication with the open inner volume of the vessel and a second end to be in fluidic communication exterior to the vessel when the stopper is engaged with the vessel wherein the fluid inlet pathway has an open condition where fluid can pass through the fluid inlet pathway and a closed condition where fluid substantially cannot pass through the fluid inlet pathway; a chamber with an inner volume for retaining a volume of preservative gas and an orifice for dispensing the preservative gas from the chamber; and a fluidic connection for fluidically connecting the orifice of the chamber to the second end of the fluid inlet pathway so that the chamber is retained externally to the open inner volume of the vessel; whereby, when the fluid exhaust pathway and the fluid inlet pathway are in closed conditions, fluid cannot be exhausted through the fluid exhaust pathway and fluid cannot be received through the fluid inlet pathway and whereby, when the fluid exhaust pathway and the fluid inlet pathway are in open positions, liquid can be dispensed from the open inner volume of the vessel through the fluid exhaust pathway and preservative gas can be drawn from the chamber and into the open inner volume of the vessel through the fluid inlet pathway in volumetric displacement of the liquid exhausted through the fluid exhaust pathway.
