Abstract: Disclosed is a system for closing containers that includes a support frame, a container feeding station and a lid closing assembly. The container feeding station receives the plurality of containers in an unsealed configuration and moves the containers linearly to the lid closing assembly. The lid closing assembly includes a transport assembly and a sealing assembly. The transport assembly includes laterally opposed first and second drive belts that each include at least one pair of articulating jaws adapted and configured for receiving one of the unsealed containers. The sealing assembly includes a press plate that moves from a first raised position to a second lowered position such that the press plate urges the lid of the container into sealing engagement with the base.

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.
