A dispensing device for flowing substances comprises a tube (19) of flexible material adapted to receive the substance in question from a conduit (13) and a valve arrangement (20) for regulating flow of substance from the tube out through a discharge opening (21). The valve arrangement has two or more valve parts (23), which are adapted to each other so as to in a first relative position shut the flow past the valve and in a second relative position open for flow therethrough. A cooling device (10) is arranged along at least a part of the conduit (13) for cooling the conduit and the substance located therein, so that particularly in the case of food substances a degradation thereof is avoided.
A valve having a linear actuator operating a tube compression rod. The rod is held in a common axial orientation with a section of flexible tubing that runs through the valve and is rigidly held therein between the compression rod and a tube platen. The flexible tube section is fluidly connected on one end thereof to a pump that delivers a viscous material thereto from a source thereof. The opposite end of the flexible tube section is fluidly connected to a dispense point. In operation, the linear actuator is operable between an extended position wherein the compression rod moves to partially occlude or compress the flexible tube section against the tube platen, and a retracted position wherein the flexible tube section is not compressed. Dispensing of the viscous substance is commenced by actuation of a switch operating the pump. During operation of the pump, the chamber valve is in its extended position wherein the flexible tube section is partially occluded. When sufficient viscous substance has been dispensed, the pump is turned off. At the same time the chamber valve is operated to move to its retracted position. Such movement results in the flexible tube section moving to its non-occluded position whereby a suction force is applied to the viscous substance at the dispense point. As a result, a small volume of the viscous material is moved away from the dispense point in the reverse direction of its normal flow for preventing dripping thereof from the dispense point.
This relates to a resealable lid and cup assembly and method for using the same. The resealable lid has an opening through which liquid flows and a valve mechanism for selectively closing the opening. The valve mechanism is provided on the underside of the lid and is biased to the open position by inward deflection of the side wall of the cup.
