ABSTRACT:
A disposable container for liquids may be squeezed to apply pressure to a sealed portion of the container to cause the sealed portion to rupture, thereby releasing the contents of the container. The sealed portion includes an inwardly projecting concavity with a nipple-like projection into the sealed portion of the container. When pressure is applied to the container, the nipple-like portion ruptures first, thereby facilitating rupture of the remainder of the sealed portion. A flow resistor may be included near the opening of the sealed portion to reduce the velocity of the contents of the container released upon rupture of the sealed portion.
