Abstract: The present invention relates to a plastic cover, preferably made of CPVC plastic, for traditional baseboard heaters. The plastic cover contains a front piece with bulges and a connected perforated top piece with back flanges. The plastic cover is supported by preferably two support brackets which are attached to the wall. The support brackets have top and bottom slots in the back and protruding arms which fit into the bulges of the front piece. The slots of the support brackets hold top and bottom angled slats that direct hot air into a room. The plastic cover is easily attached to the support brackets as the bulges snap into place over the protruding arms of the support bracket and the back flanges of the top cover piece locks onto the top slat held in place by the supporting brackets. Side pieces prevent hot air from escaping and might further include straight or corner connectors to longitudinally extend the plastic cover.

Abstract: An apparatus selectively distributes air flow through a cooler to maintain cool air over garnish in the cooler. A cooler cavity includes a lower region where the air is generated, and an upper region where a cooler lid performs the dual purpose job of regulating access to the garnish and controlling a vent for directional air flow throughout the cooler. A container of garnish rests between the upper and lower regions. A vent positions adjacently to the container. A fulcrum extends from the vent. A force, such as the cooler lid, presses down on one end of the vent to tilt the vent between the closed and the open positions. The container and the vent form a barrier between the upper and lower regions from the closed position. The vent guides air flow from the lower to the upper region, and over the garnish from the open position.
