  • Patent number: 3963226
    Abstract: A protector for the bottom edge of a refuse can comprising a band of elastomer material formed into an annulus which is sleeved over the bottom chime of a refuse can. The band is molded about a steel coil spring which forms an annular passage within the band. The passage communicates with partially closed radial ports formed band. The spring is adapted to underlie the chime and by the coils of the spring deflecting axially serves as a shock absorbing means when the container is dropped. Also, air is compressed within the passage and spurts through the leaky ports. This augments the action of the spring and absorbs the rim crushing blows.
