of manufacturing the present embodiment such as die cutting the inserts and laminating them between top and bottom continuous sheets of polymeric material this is followed by a second die cut of the now laminated insert but slightly larger than the outline of the insert itself so the polymeric material extends beyond the outline of the insert to form a gasket in accordance with the present invention a method for assembling the dual compartment dispensing tube assembly comprises placing the tube on a filling line in an indexed position suitable for filling and sealing and directing the insert into and through the filling end of the tube until the end portion of the insert extends through and beyond the orifice formed by the neck and the shoulder portion of the insert abuts the inside of the shoulder of the tube the insert is directed in such a manner so that the spine and flaps are folded into either a generally 34 z 34 shape of fig4 or the four flap laminated spine of fig5 and provide a partition which divides the tube into two compartments each of the compartments are filled and the filling end of the tube is sealed by heat crimping or the like to form a straight line seal with planar insert preferably tube neck is cylindrical and has a collet on the inner periphery thereof which engages diametrically opposed notches provided in the neck portion of the insert when it is directed into the tube if desired the terminal dispensing end of the planar insert is of a configuration which compliments that of the inner surface of the closing cap such that directed into the tube the insert extends through and beyond the orifice.
