ABSTRACT:
A package comprising a cylindrical plastic tube closed at each end by an ultrasonic band seal. The seal at one end has a sealed region which is narrower than any portion of the other seal whereby squeezing of the package produces an immediate one-shot dispensing of liquid contained therein by causing rupture of the narrow region of the seal. Various package forms include perpendicularly arranged bands to provide a tetrahedral shape, a tab extending beyond one seal to provide identification of the contents of the package, notched seals providing a tear open package, and a multiple package construction in which one fluid containing tube is contained within another.
