The mill ketchup bottle provides the convenience to children and seniors to use the bottle using less power. It is very difficult for the senior persons or even for the persons with small hands to squeeze the bottle.
This ketchup packaging replaced the squeezing with an intuitive rotation mechanism. The one portion of the top soil is lowered, which expresses the ketchup out. Because the interior is now shrunk, no vacuum is created and so no air is sucked into the interior.
