Abstract
Abstract In order to collect and dispose of waste material, a plastic bag or sleeve is provided with a collar at the mouth of the bag and a ramp secured inside and at the bottom of the bag. In use, the collar is pulled back to expose the end of the ramp, and the waste material is shifted onto the ramp using either a disposal scoop or a mitten-like pocket in the side of the bag into which one's hand may extend, to manually shift or place the waste material on the ramp. The collar is then extended over the end of the ramp so that the bag encloses the waste material and the bag is sealed in any convenient way, for example, by using pressure-sensitive material or a mechanical latch.
