Abstract: A method of forming a metallic container includes the steps of providing body and lid portions, placing the body and lid portions together, keeping portions of the body and lid portions in contact with one another, and reciprocally rotating the lid portion with respect to the body portion, thereby generating frictional heat and forming a friction weld therebetween. An apparatus for attaching the lid and body portions of a metallic container includes a base to support the body, a support assembly to support a flange of the body, and a sonitrode for contacting a flange of the lid, wherein the flanges of the lid and body are held together between the support assembly and the sonitrode. A motor reciprocally rotates the sonitrode relative to the support assembly, thereby moving the flanges relative one another to generate frictional heat and create a friction weld therebetween.

Abstract: A sonotrode specially adapted for defoaming liquids during container filing operations, has an upper body portion having a first diameter and having an upper face adapted to be mounted to a driving transducer, a middle body portion having a second diameter larger than the first diameter situated below the upper body portion, a generally conical portion situated between the upper body portion the middle body portion, and a transition portion situated between the middle body portion and a lower face adapted to be directed toward a liquid upper surface within a container, the lower face being generally rectangular.

Abstract: A method of forming a metallic container by placing body and lid portions together, keeping parts of the body and lid portions in contact with one another, and vibrating the lid with respect to the body, thereby generating frictional heat to form a friction metallic weld therebetween. Apparatus for attaching the lid and body portions of the metallic container includes a body supporting base, an assembly to support a flange of the body, a sonotrode to contact a flange of the lid so that wherein the flanges of the lid and body are held together between the support assembly and the sonotrode. A motor vibrates the sonotrode relative to the support assembly to thereby move the flanges relative to one another generating sufficient frictional heat to create a friction metallic weld therebetween.
