Abstract
The structure of a piston design to be used in a pressurized dispensing container which dispenses product that is loaded at a higher temperature where it is highly flowable but maintained and dispensed at a lower temperature where it is highly viscous. The piston has an annular sidewall with an upper end that maintains a very close tolerance to the can in which it is used. The lower end has a smaller interference fit with the container. Between the upper and lower end is a recess zone that provides a more substantial clearance with the sidewall of the container.
