Patent attributes
A clamp of the dispensing device may include a container engagement surface arranged to engage and/or disengage the clamp from the container neck when the clamp is pushed downwardly or pulled upwardly relative to the container neck. The container engagement surface may include a surface with a lower portion that slopes upwardly and inwardly, and an upper portion that slopes upwardly and outwardly relative to the container neck and that moves the clamp radially outwardly and away from the container neck as the clamp is moved vertically relative to the container neck. A latch may maintain a body portion of the dispensing device in an upper position, preventing needle insertion, until a container is suitably engaged with the base portion of the device, e.g., by a clamp. Sensors may detect engagement of a container with the device and/or insertion of a needle into the container.
