  • Patent number: 9321474
    Abstract: The invention provides a theft-inhibiting carrier which includes a body 12 having a chassis 16 on which three wheels 18, 20 and 22 are mounted. The carrier 10 includes theft deterrent means 12. The theft deterrent means is configured, when activated, to dismount the wheels 20, 22 from their respective axles 44 but to retain them connected to the chassis 16 by an elongate flexible tether to impede the movement of the carrier. Two containers 60, 62 are provided and contain chemicals which are fed via pistons 68 to a mixing device 76 and into a valuables receiving chamber in which they foam and set thereby encasing valuables contained therein. A pair of arms 88 are pivotally displaced from a retracted position to an extended position in which they protrude from the containers 60, 62. Sharpened teeth 94 are provided on the arms to further inhibit displacement of the carrier.
