A viscous substance containing tube comprises more than one lid-covered outlets. These outlets can be implemented at each of two tube's end and can be implemented on the tube's surface, between two tube's ends. Each outlet is used to squeeze out of the tube the portions located in the vicinity of that outlet by applying a squeezing force on the surface in the vicinity of chosen outlet. The simplest embodiment of the tube comprises only two outlets-an outlet per each of tube's end.
