Abstract: A synchronized music delivery system utilizes either a portable memory device including compact discs (CDs), digital video discs (DVDs) and memory sticks, or on-line or wirelessly delivered content in combination with a lighted keyboard and a sound reproducing system. A synchronized musical work, including music, lyrics and specialized coding, is recorded onto the portable memory device or is stored on a server for on-line or wireless delivery, in one embodiment by downloading the information from the Internet to the portable memory device; and in another embodiment in a stand-alone version involving pre-recording the portable memory device. The stored synchronized music in one embodiment is provided with the actual song recording, sing-along words and including letters of the alphabet to be struck on a standard alpha-numeric computer keyboard, indicia, scrollable score coding incorporating notes on a musical score and fingering or a lighted key drive, all information being synchronized with the work.

Abstract: A collapsible box with an interlocking lip-sealable plastic bag as a liner is unfolded to open the sealable bag to permit oil from a crankcase to be ecologically removed during an oil change. When all of the oil has been removed, the bag is sealed and the box with the bag is transported to a disposal site where it may be safely handled. In one embodiment, the box with the bag is provided with a capped outlet port such that the oil from the bag can be removed by uncapping the outlet port where it may be made to drain into an approved receptacle. In another embodiment the bag is adhesively secured to the walls of the box so that the bag is supported when the box is opened and upright so as to be able to receive the draining oil. In a still further embodiment the bag is folded down over the box to overlap the upper portion of the box such that opening of the box provides an expanded aperture for the bag into which drained oil may be directed.
