    摘要: The invention relates to an adaptor which enables two premade tubes such as toothpaste tubes of varying sizes to be fitted together, one inside the other to obtain a dual tube dispenser providing for separate storage of two dissimilar substances and its co-extrusion from the dispenser as and when desired upon application of external pressure on the latter. The adaptor includes a threaded component in the form of a cap with internal threads to match the threads of the neck portion of conventional toothpaste tubes. A central passage provided in the adaptor communicates with the inside of the tube to which it is screw-fitted. The adaptor is further provided with press-fitting studs to hold the tube coaxially within a larger tube to obtain a dual tube dispenser, the press-fitting studs being capable of forming a press-fit connection in the internal portion of the neck of the larger tube.
