“Imagine a flexible bag inside the product. Over the bag we have mounted a special sleeve that presses the bag in order to push material out,” explains Har-Shair.
“The special elastic sleeve is based on nano-technology and it is very thin while generating high pressure. There is zero pressure on the external container and all the pressure is directed to the center. Now we can eliminate the traditional metal container,” says Har-Shai.
