Abstract: A backpack, to be carried on the back of a user, that includes a hollow shell and a lid. The hollow shell has a substantially rigid bottom wall, and a sidewall that extends up continuously from a periphery of the bottom wall and terminates in an annular upper edge. The annular upper edge defines an opening into the interior of the hollow shell. The sidewall has a leading end and a trailing end and is also substantially rigid. A lid is rotatably connected to the shell. The lid is rotatable between an open position for exposing the opening and a closed position for covering the opening. A pair of shoulder straps are connected to the shell for supporting the backpack on the back of the user so that the bottom wall faces the user's back. A plurality of pads are affixed to an outside surface of the bottom wall. During use, the plurality of pads support the bottom wall in spaced relation to the user's back thus maintaining a ventilation gap between the bottom wall and the user's back.

Abstract: A rear bagging receptacle for a power lawn mower has a lift-off collection bag and a flip-top lid. The collection bag has a frame sewn into a flexible fabric around its mouth, the frame allowing the bag to be rested on the laterally spaced, rearwardly extending legs of a handlebar frame. The flip-top lid has an integral, stiff, recessed member and yieldable, opposing fingers at a back end of the member to pivotably and detachably mount the lid to a crossbar of the handlebar frame. There, the lid pivots forwardly and downwardly to close over the mouth of the collection bag and exit of a discharge chute extending on the front edge of the collection bag. The lid also pivots upwardly and rearwardly to allow access to the collection bag and lift-off removal of the collection bag or disposable liner bag.
