ABSTRACT:
A machine for sealing food containers is disclosed which includes a horizontal base and support means attached to the base for supporting a container to be sealed. A ring is attached to the support means which ring has a first indentation forming a concentric circle with the ring and on the surface of the ring. A second indentation lies within the first indentation. A first horizontally extending arm is pivotally linked to the base for allowing vertical movement of the arm. A vertically extending arm is attached to such first horizontal arm and extends downward and is centered within the ring. A disk is attached at its center to the vertical arm. Such disk has a diameter greater than the inside diameter of the ring but less than the outside diameter of the ring. A vertical sleeve encircles the vertically extending arm and is rotatable about such vertical extending arm. A second horizontal arm is attached to the vertical sleeve and is also rotatable about the vertical arm. A train of rollers is attached to the second horizontal arm which train includes a first smooth vertical roller adapted for moving along such first indentation on the surface of the ring, a second horizontal roller following the first roller and having a radius extending inward of the ring over the first indentation, and a second vertical roller following the horizontal roller having a projection for engaging the second indentation and adapted for moving along such second indentation on the ring.
