    摘要： The invention relates to a device for applying a viscous substance, in particular for cosmetic, writing, painting, drawing and/or marking purposes, having a tank for the substance, an applicator and a conveyor designed to convey the substance from the tank to the applicator. According to the invention, the conveyor has a cylinder, a first and a second closing device, which are both arranged in the cylinder in an axially displaceable manner, a pump tappet for axially displacing the closing devices, a first connecting channel between the cylinder and the tank and a second connecting channel between the cylinder and the applicator, the first closing device opens or closes the first connecting channel depending on its position relative to the cylinder, and the second closing device is adjustable relative to the pump tappet, opens or closes the second connecting channel depending on the position relative to the pump tappet and, together with the cylinder, forms a pump in which it serves as a piston.

    摘要： A container having a pressurized chamber containing a fluidic material and a dispensing assembly coupled thereto. The dispensing assembly includes a dispensing passageway for discharging the fluidic material from the container. A dispensing valve, a tilt valve, and a pump assembly are all operably coupled to the dispensing passageway. The tilt valve is alterable between a closed state in which the pressurized chamber is scaled and an open state in which the dispensing passageway is fluidly coupled to the pressurized chamber. The pump assembly is alterable between a first state in which a variable volume of the dispensing passageway in at a first volume and a second state in which the variable volume is at a second volume that is less than the first volume. Thus, the pump assembly creates a negative pressure behind the dispensing valve to prevent excess fluidic material from being dispensed.
