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, an upper heater platen suspended above the tray support, and an 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. The actuator may be either a manual actuator or an air actuator. The actuator is multi-axially pivotally coupled to the platen to thereby allow the platen to rock and seek and obtain a parallel relation with the container flange and lid.
