A flexible nozzle integrated with a transformable wire which provides for a greater opening of the nozzle during the distribution of a desired contents into a container. The greater opening reduces the velocity of the desired content thereby reducing or eliminating frothing which may hamper the sealing of the container. The transformable wire may be composed of a marmem material or a piezoelectric material. 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 is heated above the marmem material's critical temperature in order to open the nozzle. As the desired contents flow through the nozzle, the marmem material is cooled below its critical temperature and transformed to a second shape thereby closing the nozzle. The process is repeated for each container to be filled with the desired contents. |
