ABSTRACT:
A two-piece slide dispenser includes a housing defining an internal compartment for the storage of a plurality of reagent slides or similar items. The housing includes a dispensing opening and a loading opening. A finger or similar structure at least partially obstructs the dispensing opening to prevent inadvertant falling out of the reagent slides. A one-piece, multiple function, resilient spring boot including a biasing portion and a light and humidity sealing portion is also provided. Once reagent slides are loaded through the loading opening into the internal compartment, the spring boot is mounted in the compartment to engage the slides biasing them toward the dispensing opening. The biasing portion of the spring boot can be hemispherical or of a similar configuration allowing this portion to fold into itself. The biasing portion also includes an extension extending from the hemisphere to engage the slides. The sealing portion of the spring boot includes a lip or edge that can be secured on the housing around the loading opening. In an alternative embodiment, the lip or edge of the spring boot engages the inner peripherial surface of the housing adjacent the loading opening and the loading opening is closed by a cap.
