  • Publication number: 20080314912
    Abstract: An anti-rolling device for cylindrical containers, such as mailing tubes, has a stabilizing member with an internal aperture for inserting over a portion of the container. The outer periphery of the device is irregular, e.g., having flats, such that resting on a flat lowers the container to a stable position, and requires energy to rotate beyond the flat and consequently lift the container. The device may be slipped over a plug type cap or placed directly over the body of the container. In alternative embodiments, the device is provided in the form of a gasket, is made from a foam material, is split and resiliently grabs the container or has an elastic band holding it tightly to the container. The various embodiments may be used to retrofit an existing container. The stabilizer may be provided with one or more radial tabs, which may have burrs to grip the receptacle and/or feature a constraining ring to lock the cap into the receptacle.
