DEFINITION

Classification: 65/59.26

Metal part forced through or into softened glass part (e.g., pinch sealing, etc.):

(under subclass 59.2) Processes in which the glass part is softened by heat and the metal part is forced through or into it to fix their relative positions.

(1) Note. This subclass included those processes sometimes referred to as pinch sealing in which the heat-softened glass is squeezed down around the metal part until the glass fuses with itself.
