A disposal device (1) is used for disposal for messy dirt such as dog excrement. The device (1) provides a disposal action analogous to that of a dustpan and brush. A scooper (15) is pushed underneath the dirt on the near side, while a scraper (10) pushes the dirt towards the scooper (15). The dirt falls into the interior of the bag (2) via a chute (18) connecting the scooper (15) to a wall (4) of the bag (2). The scooper (15) and the scraper (10) are dropped into the bag (2) and the bag is then sealed by a seal (6).
