Abstract: A dispenser for paste material such as gels and creams as typically used in pharmaceuticals, personal care and food products, having a discharge channel (31) consisting essentially of resilient elastomeric tube (3), with an inlet end connected to receive material from the paste material container (1,101,201,301) and an outlet end terminating in a tip with a slit-opening e.g. a duckbill valve (33,333,433). An actuating element (5,7,8,9,9?,405) is mounted in the container behind the elastomeric tube (3), movable in a dispensing stroke laterally relative to the tube (3), and includes a blocking portion (53,253,83,93,93?) towards the inlet end of the tube (3) which moves laterally in advance of a compression region (55,255,85,95,95?) to block the tube (3) wholly or partly by squeezing it. The compression region (55,255,85,95,95?) then presses along the side of the tube (3) and squeezes material from the outlet end (36,136,336,436,5381).
