Abstract: A manual compactor that includes an air ventilation system and also a lid that is capable of being forced downward onto trash within a trash can. The trash can has a wheel base. The air ventilation system includes an internal aerated ring with a series of vent holes, with the ring being attached to a pair of internal air channels that open to the outside air. The lid is capable of either being mounted on top of the trash can or in the alternative, can be shoved downward onto trash within the trash can. A series of serrated blades mounted on the underside of the lid are used to cut up and shred the trash within the compactor while it is being compacted.

Abstract: An improved structure of trashcan includes an outer can with a controllable upper cover. The upper cover has a connecting hole with a stepping part that moves downward in the outer can when being stepped. A base is at the bottom of the upper cover. First, second, third, and fourth tracks surround the stepping part at symmetrical positions of the base. Each track accommodates a restoring assembly that connects to the stepping part so that the stepping part can restore its original position after the stepping part moves to the bottom of the trashcan. The first track and the second track are stacked vertically. The third track and the fourth track are also stacked vertically. This configuration decreases the area occupied by the base. As a result, the stepping area of the stepping part is increased for the user's convenience to step on.

Abstract: A materials handling apparatus for aiding in loading and transporting various materials has three major components, a wheeled cart, a truncated conical cylinder which is carried by the cart and a compaction lid which provide the apparatus with the capability of being operated in three different modes. In the first mode, a conventional trash bag is placed inside the cylinder and the lid can be placed atop the cylinder. In this mode, the apparatus operates as a conventional trash can. In a second mode, the cylinder in placed within a trash bag to protect it from being damaged by materials such as tree and shrub clippings or other materials which could tear the bag. In the third mode no trash bag is used, the materials are loaded into the cylinder, and when loading is complete, the cylinder is lifted off of the materials for direct deposit into a disposal site.

Abstract: A lid construction is described for compression of the content of a container, where a body in connection to the lid of the container is set up to create a pressure down onto the content such that it is compressed. It is characterised in that it comprises a moment arm construction which on rotation is set up to push the element down to its active position, and to be pulled up to its passive, rest position. The moment arm construction is preferably integrated in the lid, and it comprises compacting a relatively longer arm part (40a,40b) which is firmly connected to the relatively shorter arm part (48a,48b), and where the moment arm is rotary mounted in the lid. Also described is a construction of a docking station for a waste container and where the lid construction is integrated. Application of the inventions is also described.

Abstract: A trash compactor suitable for backpacking having two parts: a container and a removable plunger. The container is made from a tube. The ends of the tube are formed to accept caps. The caps are fitted with gaskets to prevent leaking of liquids and odors. One of the end caps has a plug to allow liquids to be drained from the container during compression. In one embodiment, the plunger has a flat press end and a handle. In another embodiment, the plunger base is fitted into one of the screw caps. The handle is a threaded shaft that screws into the plunger base. The container may be lined with a plastic bag for disposal or the trash can be stored in the container and then transferred to a separate plastic bag for disposal. The compactor can be used in recreational vehicles, boats and automobiles as well as by hikers.

Abstract: A garbage can capable of compressing garbage volume consists of an outer cylinder and a top cylinder. A top cover has a top plate with a through hole. The circumference of the top plate extends downwards to form an inner wall and the outer circumference of the top plate extends downwards to form an outer wall such that a space between the outer and inner walls can be formed. The front and the back sides of the space form a front trough and a back trough respectively and a small sheaf is placed on the front and back sections of the left and right hand walls of the space with a pedal located below the upper cover. A reset component includes mainly a first elastic part and a second elastic part. The first elastic part is located inside the front trough of the top cover, and the two ends have been fixed on a wire pedal. The second elastic part is placed inside the back trough of the top cover, and the two ends are fixed respectively on pedal with the wire.

Abstract: An upwardly opening tank including interconnected opposite side and end walls and a first stationary filter head therein is provided. A second head is mounted in the tank and is shiftable toward and away from the stationary head for clamping a plurality of filter frames between the heads. The stationary head includes inlet and outlet passages for inlet and outlet flow of fluid to be filtered and a downwardly opening cover is provided for the tank including interconnected opposite side and end walls. A lift frame swingably supports the cover from the tank for forward and downward swinging of the cover into closed position and upward and rearward swinging of the cover toward an open position with the cover disposed in a forwardly and downwardly opening attitude.
