Plunger system, device and method

A plunger for dispensing a material from a collapsible package in a package tube, the plunger comprising:

• a main wall;
• and
• a plurality of sectors extending from the main wall, each of the sectors includes a flange extending from a perimeter edge of the sectors, the flange extends away from the perimeter edge at an angle to create a plunger side between the flange of the sectors, the plunger side being configured to receive an end of the collapsible package containing the material;
• wherein the sectors adjacent to each other are separated by a slot defined through the flange and the sectors, respectively;
• wherein the sectors are configured to bend in relation to the main wall when a predetermined force is applied to the sectors by the end of the collapsible package.

A method of operating a plunger to dispense a material from collapsible package in a package tube, the plunger comprising a main wall and a plurality of sectors extending from the main wall, each of the sectors includes a flange extending from a perimeter edge of the sectors, and wherein the sectors adjacent to each other are separated by a slot, the method comprising the steps of:

• a) advancing the plunger in the package tube so an end of the collapsible package is received adjacent to the sectors;
• b) forcing the plunger against the end of the collapsible package to create a force applied to at least the flange of the sectors;
• and
• c) bending, by way of the force, the flange of the sectors in relation to the main wall so that at least a perimeter edge of the flange contacts an interior surface of the package tube.
