A sponge mop retainer is attached to the end of a handle with a sponge member removably secured within the retainer. The retainer keeps the sponge member from rolling out when the mop is in use by tending to adhere to a surface while it allows the sponge member to be removed when the sponge member is worn out or dirty. The sponge member has four opposed longitudinal slits, one on each of four opposed surfaces. The retainer has a top wall and two side walls with the bottom edges of the two side walls having flanges which project inwardly, substantially toward one another. The free edges of each of the flanges have enlargements, substantially along their length, of a greater thickness than the thickness of the flanges which are engaged in two of the opposed slits to oppose movement of the sponge member away from the retainer. The enlargements, which may be in the form of barbs, enable the sponge member to withstand the friction forces involving in cleaning a surface without becoming disengaged from the retainer.
In a sponge mop having a sponge member with at least two opposed longitudinal surfaces, each of said surfaces having a longitudinal outwardly opening slit, the slits lying generally in the same plane, a sponge retaining member having an integrally formed generally channeled-shaped structure opening downwardly and having a top and side walls, the side walls terminating adjacent their bottom edges in inwardly extending flanges extending substantially perpendicular to said side walls, said flanges having a first thickness and free inner edges, said slits having a substantially constant width less than said first thickness, said flanges engaged within a pair of said opposed slits of the sponge member to engage the sponge member with the free inner edges substantially buried in the sponge member, the improvement comprising:
A sponge retaining member, adapted to retain a sponge member having at least two opposed longitudinal surfaces with longitudinal outwardly opening slits, the slits lying generally in the same plane, said retaining member having an integrally formed generally channeled-shaped structure opening downwardly and having a top and side walls, the side walls terminating adjacent their bottom edges in upwardly extending substantially perpendicular flanges having a first thickness, said flanges having free inner edges, said slits having a substantially constant width less than said first thickness, said flanges adapted to engage in said sponge member slits, the improvement comprising:
