Abstract
A disposable container comprising a filled, temporarily sealed cartridge for use in a caulking gun-like dispenser mechanism for repeated discharge of incremental amounts of the contents thereof of mayonnaise-like consistency. The cartridge includes a generally cylindrical tubular body having an inwardly rolled rim at one end thereof with a generally circular disc sealed within the body in abutment with the rim. A plurality of mutually intersecting slits through the disc form a resilient, pressure-responsive valve and orifice in the center portion of the disc. A plug top closure is disposed within the opposite end of the tubular body and is provided with a tapered side wall sized to be closely received within the tubular body, at least one circumferential rib on the sidewall for tightly, slidingly engaging the tubular body, and a radially outwardly extending closure lip for yieldably engaging the inner surface of the tubular body and providing a liquid tight seal between the top plug closure and the tubular body. An optional radially inwardly curled lip is disclosed on the opposite inlet end of the tubular body. A delaminable laminated tubular body side wall is also disclosed along with a method of assembling such a disposable container.
