Abstract
PURPOSE:To obtain secure sealing and to shorten the exhausting time, by using an exhaust pipe of glass with a large diameter for air exhaustion, inserting a glass bar in the exhaust pipe, and melting them for sealing. CONSTITUTION:An exhaust pipe 2 with a comparatively large diameter is attached to a bulb 3, e.g., electric bulb, CRT, and is connected to a branch exhaust pipe 5 on a main exhaust pipe 4 through an airtight shield section 6. A container section 8 is formed in a part of the main exhaust pipe 4, and a bar or a tube of glass 7 with a prper size is held so that it can be moved up and down freely in the container section 8. After air exhaustion, the bar of glass 7 is inserted into the exhaust pipe 2, and is heated and melted by a burner together with the exhaust pipe 2 for sealing and cutting. According to this constitution, even if the exhaust pipe is large no crack will occur in sealing, and the exhausting time is much shortened, thereby the productivity can be improved.
