发明名称 Method for making plural chambered dispensing tubes
摘要 A plural-chambered dispensing tube is made by a method involving molding a molten resin material into a tube head while a pre-finished tube body having a partition disposed therein is disposed within the molten resin material. Thus, the pre-finished tube body and partition become connected to the tube head as the latter is being molded. In this way, the tube body and the partition are molded into the tube head to form a uniform seal between the partition and the tube head and to improve the separation of the stored components.
