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.

Abstract: A colored diskette for holding a floppy disk with an outer colored substrate sheet forming an outer envelope, the inside of which is lined by a conductive layer acting as a shield and which is lined by a liner in which the disk rests. The data stored on the disk is color-coded so that the diskette may be easily stored and classified according to the color of the substrate.
