Abstract:
A device for examining breaking resistance of a glass bottle by applying inner pressure thereto. The device includes endless conveying means for repeatedly transferring pressure fluid ejection head groups at equal spaces to a bottle examination zone provided on the path along which bottle to be examined are conveyed and conveyors for transferring the bottles synchronizing with the movement of the pressure fluid ejection head groups in the examination zone, each pressure ejection head including a vertically movable nozzle connected to a pressurizing fluid source and a packing capable of rapidly resiliently deforming and bulging out at one end of the nozzle. When the nozzle is inserted into the bottle, the bottle mouth is sealed by the packing which resiliently bulges outwardly, and a valve for a pressurizing fluid passageway is opened to fill the bottle with pressure fluid.
