  • Patent number: 5996427
    Abstract: A liquid sample storage device which utilizes a liner-holder with a liner which may be disposed of after use, thereby eliminating contamination problems associated with reusable bottles. The liner-holder is a hollow, wedge shaped container with an upwardly extending neck section and vents on the top and bottom, as well as a plurality of vents on each of its sides, to allow adequate displacement of air from within the container as the liner fills with the liquid sample. Two embodiments utilize a liner-holder which may be opened into two sections along a vertical hinge to provide access to the interior for proper positioning and later removal of the liner. The liner is positioned within the liner-holder, secured at the neck, and then suspended within the liner-holder by snap-locks or a support hook to facilitate the input of the sample into the liner.
