A plurality of pressure resistant walls are formed between the inlet and the outlet to form an internal volume to reservoir water within the water vessel. The water vessel is constructed to reservoir water within the vessel under hydrostatic pressure from the water supply line until dispensed through the outlet when requested by the exterior water dispenser and/or the icemaker.

Aqueous compositions formed from combining water, and at least one solute such as sodium bicarbonate, acetylsalicylic acid or mixtures thereof, are used to introduce and maintain relatively high levels of carbon dioxide in the atmosphere of selected environments. The aqueous compositions benefit live plants and prolong the shelf life of various perishable foods and products, including vegetables, fruits, meats, fish, seafood, dairy products, and dry goods and ingredients. The aqueous compositions are applied directly by bathing or showering a perishable product in the aqueous compositions, or indirectly with absorption devices that carry the aqueous compositions, and which are placed in close proximity to a perishable product. An aqueous composition can be applied to or formed directly on an absorption device. An absorption device can also be recharged by reapplying or reforming the aqueous composition to the absorption device as needed.

It is intended to provide a process for producing a packaged drink whereby filling can be performed at room temperature without resorting to using a chemical or sterile water, the favorable taste and flavor of the content can be maintained while relieving the thermal degradation thereof, it becomes unnecessary to employ a heat-resistant container or to thermally sterilize or cool after sealing, and thus both of the equipment cost and the running cost can be largely reduced. After thermally sterilizing the content to give a definite sterilization value, it is quickly cooled to room temperature and then stored in a storage tank that has been preliminarily sterilized under such conditions as being equal to or exceeding the thermal sterilization conditions for the contents. While maintaining the storage tank under positive pressure with the use of a sterile gas, the content is fed into a filling machine that has been preliminarily sterilized under such conditions as being equal to or exceeding the thermal sterilization conditions for the contents. Thus, the liquid-feeding system ranging from the storage tank to the filling machine is made a closed liquid-feeding pathway free from the invasion of air from the outside. The drink is filled into a container having been sterilized with hot water in an environment-controlled space isolated from the outside wherein the surroundings have been thermally sterilized and washed with hot water at 65° C. to 100° C.

Simple carboxylic acids, in particular dicarboxylic acids such as citric acid shows an unexpected ability to enhance the antimicrobial power of a wide range of disinfectant and/or antibiotic agents. As little as 1% citrate greatly enhances the ability of antibiotics to kill or inhibit a wide range of bacterial species including antibiotic resistant strains. Citrate alone is effective in preventing bacterial growth in platelet concentrates and in red blood cell suspensions. Effective concentrations of citrate cause little if any damage to blood cells. Besides enhancing the power of antibiotics citrate also enhances the antimicrobial properties of disinfectant organic dyes such as crystal violet and methylene blue. In addition citrate enhances the antimicrobial properties of polyphenols of plant origin. Iodine-based disinfectants are also enhanced without enhancing protein denaturation.
