ABSTRACT:
A packaging assembly for two different substances, which are to be mixed by the consumer, consists of an ampule containing one substance, enclosed within a tube containing the other. Both components are made of plastic, and at least the ampule is so constructed as to permit it to be opened by manual compressive force applied through the tube body. The cavities of the ampule and tube are desirably closed simultaneously, as by forming a common heat seal across them.
