Our dispenser mechanisms and functions:

1. Uses only 2 levers:

I -Selection of potato flavored crisps

II-Rotating coin slotting device which also dispenses the

crisps container.1. Rotating mechanism coin slotting device (concept of a candy

dispenser)

2. The potato container are stacked vertically into the partition

box and uses gravity to position itself into the plunger zone.

3. The plunger pushes the potato crisps container out of the

partition box and the container falls sliding down the ramp.

4. Only two 50 cent coins are used.
