Abstract
A diagnostic reagent dispensing bottle which includes a flexible container having an elongated cap mounting neck which is closed by a pierceable or punctureable membrane. A membrane-piercing-and-droplet-dispensing spike is also provided. The spike includes a conically-shaped orifice and a sharp membrane piercing point. The spike is carried by an elongated cap which has a body portion for mounting on the neck of the container. The neck and cap cooperate to position the spike in either (1) a shipping or non-piercing position or (2) a dispensing position wherein the spike pierces the membrane so that the reagent within the container can flow through the spike for dispensing. The cap also includes a cover or closure for closing the bottle which is hingedly connected to the cap body so that the cover is selectively positionable in either an open or closed position. Both detent and thread systems are disclosed for cooperation with the cap and neck to position and guide the spike relative to the pierceable membrane.
