Package for a flowable material susceptible to flavor loss

Abstract

A package comprising, an elongated collapsible tube defining a chamber to receive a flowable material, with the tube having a tapered shoulder, and a hollow neck having an inner end extending from the shoulder, and an outer end. The shoulder normally causes flavor loss of the material in the region of the chamber adjacent the shoulder. The package has an insert comprising a tubular section having an outer end connected to the neck, and an inner end extending into the chamber a sufficient distance to prevent extrusion of the material in the region of the shoulder through the neck.
