Container assembly and method for making assembly

摘要

The present invention is directed to a container assembly and a method of manufacturing thereof. The container assembly includes an outer tube within an inner tube and a venting pathway extending between the inner surface of the outer tube and the outer surface of the inner tube. The venting pathway includes a combination of a textured surface area and a longitudinal groove for allowing air to vent to atmospheric pressure during insertion of the inner tube within the outer tube.
