Vial filling apparatus

Abstract

Apparatus for filling sterile containers is disclosed which defines an elongated but narrow sterile zone in which a number of operating stations are disposed. An elongated vertical wall is armed by an elongated frame and a cabinet type enclosure cooperates with the vertical wall to define the sterile zone. The plurality of operating stations are disposed in sequential relation over the length of the sterile zone, and an elongated container conveyor is disposed within the sterile zone to convey the containers through the plurality of operating stations. The conveyer is vertically oriented, consisting an endless belt mounted on end wheels that rotate on horizontal axes. Each of the operating stations includes an operating portion disposed within the sterile zone. Actuating means are included for each of the operating stations as well as the elongated conveys, each of which is disposed outside the sterile zone. Connecting means operabably connect each of the actuating means outside the sterile zone through the vertical wall to the associated operating station within the sterile zone. By orienting the conveyor vertically and disposing the various actuating means outside the sterile zone in side-by-side relation, the effective width of the sterile zone is significantly reduced. As a result, the sterile zone is more easily accessed, and also more easily drained after washdown operations. In addition, the sterile zone of reduced size results in an apparatus that much easier to manufacture and maintain in a sterile state.
