The present invention relates to plural compartment assemblies in which materials are stored in at least two separate compartments until the compartments are opened for use. More particularly, the invention relates to a dispensing tube whereby the utilization of a novel insert, a conventional dispensing tube can be divided into separate and discrete compartments at a low cost. The resulting dispensing assembly provides for dispensing more than one material from the same tube and even more particularly co-dispense predetermined proportions of incompatible materials simultaneously and effectively.

A substantially planar partition-forming member suitable for insertion into a dispensing tube to form a partition and two separate and discrete compartments within the tube; said tube having a dispensing end with affixed thereto a shoulder and a neck terminating as a dispensing orifice and adapted to receive a closing cap and an open filling end into which the partition-forming member is inserted prior to filling; said partition-forming member having a configuration such that when inserted into the tube; (i) the end of the partition-forming member corresponding to the dispensing end of the tube is substantially equal to the inner diameter of the neck and extends into said neck, (ii) the adjacent portion thereto conforms to the shape of the tube shoulder, (iii) the mid-portion extends within the tube and has a width corresponding to at least one half the inner-circumference of the tube; and (iv) the terminal end of the partition-forming member corresponding to the filling end of the tube has a width substantially equal to one half the inner-circumference of said tube, said partition-forming member being scored along each longitudinal side at a distance from the edge thereof such that when fully inserted into the tube the partition-forming member folds along the scoring thereby providing a spine between the scoring and two flaps adjacent thereto; and said partition-forming member being comprised of a material sufficiently resillient that such member tends to revert to its original planar configuration thereby causing pressure of the flaps against the inner surface of the tube and providing a seal along the longitudinal edge with said inner surface of the tube. A method for assembling a dual compartment dispensing tube assembly, said assembly comprising: a tubular container body having a dispensing end and a filling end, and a shoulder and a neck terminating as a dispensing orifice and adapted to receive a closing cap affixed to the dispensing end of the tube; a substantially planar partition forming insert member having a configuration generally conforming to that of the tube if flattened and comprising: an end portion which is substantially equal to the inner diameter of the neck; an adjacent portion thereto conforming to the inside shape of the tube shoulder; an elongated mid-portion having a width of at least one half the inner circumference of the tube; and a terminal end having a width sub-stantially equal to one half the inner-circumference of the tube; scoring along each longitudinal side of the insert to provide a spine between the scoring and an elongated flap at either side of the scoring said insert comprised of a material sufficiently resilient such that the insert tends to maintain its planar configuration; said method comprising: (i) placing the tube in a position suitable for filling; (ii) directing the planar insert into and through the filling end of the tube until the end portion of the insert extends into the orifice formed by the neck, the adjacent portion abuts the inside of the shoulder, and the spine and flaps are folded into a generally “Z”shape and provide a partition which divides the tube into two compartments; (iii) filling each of the compartments; and (iv) sealing the filling end of the tube to form a straight line seal with the planar insert.
