Abstract
Abstract Disclosed is a protective housing unit for a liquid sample container. Basic components include an outer housing member and an inner housing member, which are defined by cylindrical sections. The outer member has an open top, an opening in the side wall, and a bottom which connects to a drain line. Positioned within the outer member is a plate for supporting a liquid sample container, such as a bottle. The inner member has an open top, an open bottom, and an opening in the side wall. Also, the inner member is adapted to fit down into the outer member and to rotate within the outer member. A liquid sample is directed into the container through a fill pipe, which connects to an inlet line and which extends through the top of the inner member and down into the container. During filling, the sample container can be completely enclosed by rotating the inner member to mis-align the side wall openings in each member. After filling, the inner member is rotated to a position which aligns the openings, to permit removal of the container.

A protective housing unit for a liquid sample container, which comprises the combination of: an outer housing section defined by a cylindrical section which has a single side wall, an open top, a bottom which connects into a drain line, and an opening in the side wall; a support plate for supporting a liquid sample container, the plate being positioned within the outer housing section near the bottom of the section; an inner housing section defined by a cylindrical section which has a single side wall, an open bottom, an open top, and an opening in the side wall, the inner section being positioned within the outer housing section, and the inner section being rotatable within the outer housing section; a tee fitting which has an upper end in communication with a liquid inlet line, which has a lower end in communication with the open top of the inner housing section, and which has a branch end in communication with a vent line; a fill pipe which is positioned lengthwise within the tee fitting, such that an annular space is defined between the fill pipe and the tee fitting, the fill pipe having an open upper end in communication with the liquid inlet line and an open lower end which extends into the sample container, the annular space defining a passageway for diverting vapors from the sample container into the vent line; the inner housing section being rotatable to a first position which will seal the opening in the outer housing section and enclose the sample container, and to a second position in which the opening of the inner housing section will be in alignment with the opening of the outer housing section, to permit the sample container to be inserted and removed from the said housing unit.
