Abstract: A quadrilateral refuse container (2) comprising a bottom (8) and four sidewalls (6) extending upwardly therefrom and terminating in an upper rim (64). The container further comprises a handle (52) extending outward from at least one side of the container, the handle having two parallel spaced apart sideplates (54), each sideplate having a lower edge profile for defining a downwardly concave recess (62). When one container is stacked inside a like-configured second container, the upper rim of the bottom container is nested within the handle sideplate recesses of the top container, and the sidewalls of the underlying container are held in a fixed vertical orientation. Recesses (49) are further provided within sidewalls (6) of the container, adapted to receive handle projections from a like configured second container, whereby the containers can be stored in a side by side abutment.

Abstract: A refuse container and dolly assembly in which the refuse container and dolly includes a square or rectangular transverse sectional configuration. An alignment flange is provided in the top surface of the dolly, adapted to engage a registration flange in the underside of the container, whereby, upon rotary connection between the dolly and an underside of the waste container, the side walls of the dolly and the waste container are brought into co-planar alignment.

Abstract: A mop wringer (10), which is adapted to be positioned on the rim of a pail or the like, includes a body member (11) having a front wall (14). A pressure plate (30) is pivotally connected to the body member (11). The inner surface of the front wall (14) has passageways (15A) therein and the outer surface of front wall (14) is formed with a downturned lip (59) to define additional passageways (15B) below the passageways (15A). A rotatable arm (41) carries a linkage mechanism (49) which is connected to the pressure plate (30). Rotation of the arm (41) pivots the plate (30) to evacuate water out of a mop positioned between the plate (30) and the front wall (14). The water passes through the passageways (15A) and is downwardly directed in the pail through the passageways (15B) by contact with the downturned lip (59).
