Abstract: A fluid dispensing unit includes a hollow support enclosing a collapsible reservoir or container. The container has a one-way valve at its outlet for directing flow through the valve into a metering chamber. The metering chamber has an outlet connected to another one-way valve which valve prevents any backflow of contaminants into the container after fluid is dispensed. As the fluid is dispensed, the container can be collapsed to ensure complete evacuation of the fluid. Further, the metering chamber can be completely collapsed to ensure that the dispensing unit is completely empty.

Abstract translation: 流体分配单元包括封闭可折叠储存器或容器的中空支撑件。 容器在其出口处具有单向阀，用于将流动通过阀进入计量室。 计量室具有连接到另一单向阀的出口，该阀在分配流体之后防止污染物进入容器的任何回流。 当流体被分配时，容器可以折叠以确保完全排出流体。 此外，计量室可以完全折叠以确保分配单元完全空。
