  • Patent number: 6862960
    Abstract: A device for loosening threaded lids from correspondingly threaded containers, comprising a body carrying first and second flexible belts (20, 26) forming first and second loops which engage around the lid and the container respectively, the belts (20, 26) being arranged to be relatively displaceable such that the first and second loops grip the lid and the container respectively, the belts further being arranged to be displaceable by an actuating means such that the first and second loops apply oppositely directed torques to the lid and container respectively whereby the lid is rotated on the container in a loosening direction. Both the lid and the container are thus gripped by the device rather than by hand. The loosening of the lid may be achieved by the rotation of only one of the loops relative to the body, the other loop serving to prevent rotation of the lid or the container relative to the body. Alternatively, both of the loops may rotate relative to the body in opposite directions.
