Abstract: A suitcase is provided with a compressive liner encapsulating an air tight packing chamber and having a sealable opening to allow placement and removal of clothing and other articles within the packing chamber. In a relaxed state, the volume of the packing chamber is substantially greater than the volume of the suitcase interior, thereby enlarging the available packing space. When the liner is filled and sealed closed, air is withdrawn from the packing chamber by a motorized vacuum pump, causing the liner to collapse and compress the contents, thereby reducing the volume of the packing chamber to a size which fits within the closed suitcase. A one-way valve holds the vacuum within the chamber, maintaining the liner in the collapsed state until the opening is unsealed.

Abstract: A cover for attachment to a traffic light is provided including a transparent shell having an aerodynamically configured outer surface and a peripheral edge surrounding an interior of the cover, the peripheral edge including a seal thereabout to prevent moisture from entering the interior and accumulating on an inner surface of the cover when attached to the traffic light. Once attached, the cover provides an overall aerodynamic configuration to the combined traffic light and cover assembly while permitting visibility of the traffic signal lights through the transparent shell.
