ABSTRACT:
By providing two endless loop belt drive assemblies forming a belt driven sealing section, a highly efficient and effective automatic, universally applicable, container closing system has been achieved which is capable of securely lockingly engaging both locking lug/receiving well containers and perimeter seal containers. In the present invention, the two cooperating endless loop belt drive systems are mounted in juxtaposed, spaced, cooperating relationship with each other and are positioned for simultaneously closing and securely engaging the entire locking elements formed on the flanges of one side of the container. In addition, the spaced distance between the two belt drive assemblies is adjustable, as well as the position of the spaced distance relative to a conveyor. In this way, all containers are to be closed by this system.
