  • Patent number: 8627536
    Abstract: A latex ink removal device to aid a user in scratching off instant lottery tickets is herein disclosed, comprising a stylus made of aluminum or a similar durable material that will stand up to tough use as well as allow it to be carried in a pocket or purse. A first end of the device is of a flattened yet curved profile similar to that of a fingernail or edge of a coin. It is used to remove the scratch-off material off of instant lottery tickets. A second end of the device is provided with a replaceable rubber-based eraser that is used to rub off the lighter covering material on some other types of instant lottery tickets such as “Bingo” and “Cashword”. Since this eraser material will wear down with use, it is sold as a replaceable part that can simply screw on and off using a threaded connector.
