A container (10) adapted for use in the detection of aerobic microorganisms in a sample includes a non-toxic insert (22) disposed within the container (10) for supporting microorganisms adhered thereto and for increasing microbial exposure to oxygenated growth media to enhance microbial metabolism. A method for making the container (10) includes the steps of inserting a non-toxic insert (22) into the container (10) and adding growth media (14). Also, a method of detecting aerobic microbiological growth in a sealed sample container (10) having a headspace (16) and which contains a sample which may contain an unknown microorganism includes the steps of providing a sealed sample container (10) having a headspace (16) and non-toxic insert (22) saturated with microbiological growth media (24), inoculating the insert (22) within the sealed sample container (10), and monitoring metabolism in the container (10) as an indicator of the presence of microorganisms to detect microorganisms in the sample.

Microbiological culture bottle, and method of making and using same

A container for holding and dispensing carbonated beverages characterized by a top portion, a bottom portion, and a side wall portion in the form of collapsible tubular bellows. A valve for dispensing a fluid is removably mounted on the container and communicates with the interior portion of the container. The valve includes a valve chamber having an opposing fluid inlet and fluid outlet and two oppositely disposed valve seats positioned adjacent to the inlet and the outlet respectively. Two oppositely disposed poppet valves, each having a stem centrally extending therefrom, are cooperatively movable between a closed position sealingly engaging the valve seats and an open position allowing fluid flow through the valve. The poppet valves are coupled to a shaft by the stems. The shaft is arranged to move linearly in a direction perpendicular to the longitudinal axis of the valve between a first position and a second position such that the shaft urges each of the poppet valves into the open position when the shaft is in the second position.

Beverage container and dispenser

A fluid applicator includes a suction bulb, a screw cap, a finger support, an inner shaft, and an outer shaft that ends in a spatulate dispenser. The suction bulb connects with the thin tubular inner shaft, which extends throughout the applicator to terminate at a release opening in the spatulate dispenser. The suction bulb, which is preferably made of rubber or flexible plastic, has a toroidal lower lip that hooks over a complementary toroidal projection of the screw cap. The tubular inner shaft has an upper lip that projects horizontally into contact with the inside of the suction bulb and that rests on the toroidal projection of the screw cap. The screw cap, which is innerly threaded, is positioned immediately above and integral with the oblong winged member that provides finger support for a user. Also integral with the screw cap and finger supports is the outer shaft, which shields the inner tubular shaft and is configured mainly as a cylinder. The spatulate dispenser at the end of the outer shaft has rounded edges, and may be tapered. Within the spatulate dispenser the inner shaft may be strictly tubular or tapered, with a small and mainly circular release opening, or may expand into a broader reservoir having a more extensive release opening. In an alternative embodiment, the inner shaft is eliminated and the outer shaft serves as the receiving tube for the fluid to be applied.
