Patent ID: 7146782

Claim:
A method of bonding a plug to an interior surface of a cartridge body formed of a continuous loop sidewall, the cartridge body combining with the plug and an end disk spaced from the plug to form a dispenser cartridge used to hold and dispense food sauce, a containment region for the dispenser cartridge defined between the plug and the end disk and bounded by the cartridge body, the method comprising the steps of: positioning the plug having a body with a terminal perimeter edge within the cartridge body at an orientation such that the thermal perimeter edge is immediately adjacent to the interior surface of the cartridge body; and applying a layer of hot melt adhesive to the terminal perimeter edge of the plug on the outside of the containment region of food sauce to seal the plug with the cartridge body interior surface and prevent food sauce disposed within the containment region from exiting the region by flowing around the terminal perimeter edge of the plug along the cartridge body interior surface.
