ABSTRACT:
A container and lid sealing apparatus comprising a frame structure including a sealing position, support beams, a shiftable container support which includes a container retainer and shiftable on drawer rails from a position for loading and unloading a container into and out of the retainer, to the sealing position for sealing a lid on the tray, the drawer rails being vertically depressible with the container support, when under vertical force, to move it down onto the support beams, an upper heater platen suspended above the tray support, and an air actuator actuable to force the upper heater platen downwardly with force onto a container and lid on the support. The force is equally distributed on all portions of the platen to seal a lid onto a container. A cam switch is positioned to be actuated by the support in the sealing position for controlled activation of an air logic system to the actuator. A gas spring is connected between the support and frame for biasing the support toward the load-unload position, for ejection of the support upon deactivation of the air actuator.
