Zusammenfassung:A getter assembly (10) has an annular channel (11) containing getter material (22 min ). The bottom (18) of the channel (11) is provided with an annular, integral, groove (20 min ) of bulb-shaped cross-section which extends into the channel (11) to lock with the getter material (22 min ). The bulb-shaped cross-section of the annular groove (20 min ) is produced by pressing getter material into the channel (11) which is provided initially with an annular groove of sinusoidal corss-section. Pressing the getter material into the channel (11) also deforms the cross-section of the annular groove to the bulb-shaped form.
