Carton forming, sterilizing, filling and sealing machine

Abstract

The disclosure illustrates and describes a modular forming, sterilizing, filling and sealing machine for containers, including a front bottom forming and sealing section; an intermediate sterilizing section; and a rear filling, top forming and sealing section; and separate conveyor means in each section. The conveyor means in the sterilizing section is adapted to receive the containers from the conveyor means in the bottom forming and sealing section in an upright, open-topped condition and convey same transverse to the line of travel in the forming and sealing sections through a sterilant vapor atmosphere wherein the sterilant vapor condenses on all surfaces of each upright, open-topped container, and then rotates the containers from the upright position to an upside-down condition through a heated and air blown atmosphere, and back to an upright condition onto the conveyor means in the filling, top forming and sealing section.
