Beschreibung
Zusammenfassung:	A dispensing device for an inter-reactive multi-component composition, such as an adhesive or filling or composition, comprises a generally cylindrical housing (1) provided with a delivery nozzle (16) at one end and a piston (3) at the other end, the space therebetween being capable of containing an unmixed inter-reactive multi-component composition (2). Adjacent the delivery nozzle, the housing is provided with a mixing means communicating with both the housing and the delivery nozzle and comprising a plurality of substantially concentric baffles (9, 10) providing a flow path for the components of the multi-component composition such as to cause substantial mixing of the components within the housing (1) prior to passage through the delivery nozzle (16).
