Syringes.-In surgical or like syringes comprising a glass barrel 1 having a delivery nozzle 5a the usual plunger packing of cotton or the like wound between flanges 4, 4a, on the plunger rod 2 is replaced by a rubber plug 6 having an internal chamber to receive the flange 4a and shaped at its end to conform with the barrel 1 in order to ensure the complete extrusion of the syringe contents. The Provisional Specification also describes a plug comprising a cup-like fitting on the end of the syringe plunger.
