Abstract
A process for blow-molding and coating plastic containers under conditions of positive control in a close-coupled, compact machine to enhance operational efficiency. According to one of the preferred methods, the containers are coated promptly after the containers are discharged from hot molds to take advantage of the residual heat of the freshly blown containers to enhance curing/drying of the coating and to enhance bonding of the coating to the container surface. According to another one of the preferred methods, the containers are aseptically filled and capped either before or after the containers are coated. Alternatively, the process can include hot-filling and capping of containers in which the containers are coated promptly after being hot-filled to take advantage of the elevated temperature of the hot-filled containers.
