The device also includes a carrying container configured and sized for receiving the collecting container and carrying container lid. The carrying container lid is attachable to the carrying container upper peripheral edge for forming together with the collecting container a collecting enclosure. The carrying container lid is also attachable to the collecting container base wall for acting as an anchoring component for the device.
