摘要： A flexible nozzle (10, 22) integrated with a transformable wire (16, 24) which provides for a greater opening of the nozzle (10, 22) during the distribution of a desired contents into a container (20). The greater opening reduces the velocity of the desired content thereby reducing or eliminating frothing which may hamper the sealing of the container (20). The transformable wire (16, 24) may be composed of a marmem material (16) or a piezoelectric material (24). A marmem material is a shape memory alloy. For example, the marmem material may be a nitinol alloy. If a marmem material is utilized, the wire (16) is heated above the marmem material's critical temperature in order to to open the nozzle (10). As the desired contents flow through the nozzle (10), the marmem material is cooled below its critical temperature and transformed to a second shape thereby closing the nozzle (10). The process is repeated for each container (20) to be filled with the desired contents.
摘要翻译：与可变形线（16,24）成一体的柔性喷嘴（10,22），其在将期望的内容物分配到容器（20）中时提供喷嘴（10,22）的更大开口。更大的开口减小了所需内容物的速度，从而减少或消除可能妨碍容器（20）的密封的发泡。可变形导线（16,24）可以由母材（16）或压电材料（24）构成。 marmem材料是形状记忆合金。例如，母材可以是镍钛诺合金。如果使用母材，则将线（16）加热到高于母材的临界温度以便打开喷嘴（10）。当所需的内容物流过喷嘴（10）时，将马姆姆材料冷却到低于其临界温度并转变成第二形状，从而关闭喷嘴（10）。对于每个容器（20）重复该过程以填充所需的内容物。
