Abstract (en)
[origin: EP0221362A2] The dispenser for viscous materials, in particular toothpaste, has a piston (13), which is arranged displaceably in a dispenser housing (10), moves in the direction of a discharge valve (12) during dispensing and is blocked in the opposite direction by a barrier (clamping module 11), and a pushbutton actuation surface (14) which is provided on a head piece (15) of the dispenser housing (10), which head piece can be compressed in the manner of a bellows, the discharge valve (12) arranged on the head piece (15) opening under the pressure arising in the dispenser housing (10) due to the compression of the bellows-type head piece (15). For easier production and handling of the dispenser and for the purpose of a defined discharge of viscous material, the discharge valve (12) has a closure flap (16) which is linked (link 23) as an integral component of the head piece (15) on only one side of the discharge opening (17) in such a way that it releases the discharge opening (17) in the event of pressure in the dispenser housing, but otherwise closes said discharge opening. <IMAGE>
