    • PROBLEM TO BE SOLVED: To suppress the deformation of an internal face when a glass panel in a high temperature state immediately after being press shaped by an upper mold is cooled in a process for manufacturing the glass panel for a cathode-ray tube.
      SOLUTION: A cooling unit is constituted of a cooling air supplying tube 3 for supplying cooling air and a blowing-out section 4 attached to the lower end of the cooling air supplying tube 3. The blowing-out section 4 comprises a side wall part 12 and a top plate part 5 connected to the upper end of the side wall part 12, and has a blowing port in an opened state at the lower end of the side wall part 12, and at least one opening part 6 is provided in the top plate part 5. Thereby, the pressure distribution of the cooling air in the panel 1 is made uniform and the deformation of the internal face of the panel can be suppressed.

    • PROBLEM TO BE SOLVED: To obtain a method for cooling a hollow glass formed body which solves various problems associated with forming and solves the deficiency of the cooling capacity of a panel while preventing the deformation of the inside surface of the panel by an air pressure by optimizing the temp. distribution at the time of cooling the panel. SOLUTION: Fused glass is supplied to a lower die 4 and an upper die is lowered to press form this fused glass, following which the upper die is risen to open the dies and air is blown from a duct having an annular blow-off port 3 to the hollow glass formed body 5 in the lower die 4 to cool the formed body. This duct is formed of double structures consisting of an outside pipe 1 and an inside pipe 2. This inside pipe 2 is fixed by mounting its circumference at the outside pipe 2. The annular blow-off port 3 is disposed between these two pipes. The cross sectional shape of the annular blow-off port 3 is selected by the shape of the hollow glass formed body 5 to be cooled. The shape may be a elliptic shape or an approximately rectangular shape in addition to a circular shape. In a more preferable embodiment, the central part at the front end of the duct enclosed by the annular blow-off port 3 of the duct is provided with a pooling part 6 for the air.
