This device provides a new way to improve the efficiency of a container that is filled with semi-fluid, for example: in cosmetics-related containers (toothpaste, moisturizer, etc.), paints, syringes, etc. The main body could be a cylinder, a hexagonal column, or even multiple edged columns. There is a piston inside the container that pushes the semi-fluid towards the opening, and the piston is connected to a button that is external of the main body. /0/0 /MN MMMMMMM, |
