ABSTRACT:
An automated lid mounting and sealing apparatus for containers comprised of a conveyor belt, a lid dispenser to feed lids one at a time as a container passes by on the conveyor belt; a lid mounting press belt, a lid closure section for closing a tear band on the lid and a lid sealing section for sealing a tamper resistant device around the lid. The lid dispenser drops a lid into a chute to be withdrawn as each container passes the dispenser. The container with the lid then passes beneath a press belt that snaps the lid in place on the container. A tear strip band on the lid is then folded under the lid and rim by a closure section. In an optional embodiment the closure section is not used and a plastic shrink band seal is placed on top of the container around the lid. Heat is then applied in a sealing section as the container is rotated to secure the tamper resistant protective device around the lid and container.
