Abstract: A plastic blow molded containr and lid combination wherein the double-walled lid is screwed to the top of the container and a parallel pair of horizontal recesses are provided on opposite sides of the container wall for receiving forks of a forklift for lifting and otherwise manipulating the container with a conventional forklift. The bottom of the container is also provided with forklift access recesses for lifting and manipulating the container from the bottom with a conventional forklift. The underside of the lid is provided with a protrusion for engaging the upper end of a salvage drum within the container to confine the drum between the top and bottom of the container. An override lid lock mechanism is provided to prevent the lid from accidentally unthreading itself. In addition, central portions of the bottom of the container are recessed upwardly with respect to perimeter portions of the container bottom so that the container in an empty condition will stably rest on a surface without easily tipping.

Abstract: A cleaning system utilizing a hollow bodied, disposable dispensing capsule or package comprising a storage chamber and integral dispensing chamber made of a plastic material. The package is connected to the system handle via a conical protrusion on the package closure. An orifice separating the two chambers is provided with a movable, inlet clapper valve, the dispensing chamber outlet orifice being normally closed by a spring urged valve. Deformation of the elastic walls of the bellows shaped dispensing chamber dispenses a discrete amount of liquid to the system handle without relying on gravity. Compression of the dispensing chamber reduces the volume thereof, closes the inlet clapper valve, and opens the outlet valve to dispense the product. The conically shaped storage chamber provides for ready pumping and evacuation of cleaning fluid therefrom, the flexible walls collapsing inward as a result of the vacuum created by the decompression of the dispensing chamber.

Abstract: A multifunction cleaning wand having a disposable head. The cleaning head is removably attachable to the wand handle. A first cleaning element in the shape of a swab is secured to a retainer by a flexible strap. The retainer is removably attached to the cleaning head. A second cleaning element is attached to the head on a side thereof opposite the swab. A method for assembling the cleaning wand is also disclosed.

Abstract: A cleaning system (60) includes an elongate handle (61) having a surface cleaning means (65) disposed at one end of the handle and a cleaning fluid cartridge means (64) disposed at the other end of the handle. The cleaning system further includes a means for pumping (66) the cleaning fluid from the fluid cartridge means to the surface cleaning means, and the pump means (66) is associated with the cleaning fluid cartridge means.

Abstract: A caddy assembly for storing a cleaning wand. The caddy includes a housing for storing the wand cleaning head, the wand handle extending downward through a groove in the housing. The caddy housing may be readily locked in an open or closed position by engaging the cleaning wand with the housing lid or a bracket mechanism, respectively. The assembly also includes apparatus for mounting the caddy in a vertical, upright position.

Abstract: A molecular model building set for the formation of models of molecules and compounds primarily in the field of organic chemistry is disclosed. The set includes dimensionally accurate model building members (10, 60) that are rotatable about their axes, and can be interconnected and/or interlocked to form specific molecular models. Model building members depicting a double molecular bond (80) and a triple molecular bond (90) are also provided and can be interconnected and/or interlocked with the model building members (10, 60). All of the aforementioned model building members (10, 60, 80 and 90) are formed from a polypropylene copolymer material resulting in the members being inherently flexible while retaining sufficient rigidity to depict strain in molecular bonding. Because of this flexibility, the rotatability of the members, and the manner in which the members can be interconnected and/or interlocked, models of all known molecules and compounds in the field of organic chemistry can be formed.
