The contents extractor for jars is a device that is inserted into a food jar or household container. The extractor has a handle with an actuator that the operator squeezes; an elongated mechanized shaft that transmits movement from the actuator; and, a flexible material that retracts and transforms into a 360° disk shape to the inner surfaces of container. When the extractor is inserted into the jar and retracted, the operator pulls the entire device upward out of the container, thus removing the residue remaining. The extractor allows the consumer to use more of the product than would otherwise be possible, thereby saving money for the consumer and reducing resources used to make the product.
