Abstract
A means for and method of closing an opening in a body housing electrical component means having external terminal means. The means for and method of closing the body includes immersing in a bath the body having an opening communicating with a void in the body and electrical component means in the void in the body. The body immersed in the bath has the void filled with material of the bath thru the opening. While immersed in the bath, the body is contacted with means for closing the opening of the body so as to retain the electrical component means and material of the bath within the body. The closed body with the electrical component means and material of the bath is then removed from the bath. The means and method have particular applicability to closing open ends of plastic bodies housing electronic components such as capacitors while the bodies and components are immersed in a bath of liquid material. In the event the electronic component is a paper type capacitor, the bath is a liquid material such as oil or wax-oil compounds having a high dielectric constant. Preferably, the open ends of the plastic bodies are closed by ultrasonically welding plastic material to the plastic bodies to close the open ends of the bodies while the bodies and their cooperatively associated electronic components are immersed in the liquid bath.
