A cleaning tool for cleaning a surface is disclosed. The cleaning tool comprises a cleaning frame including a rigid body defining a perimeter surrounding an interior opening and at least one spacer arranged within the interior opening. The cleaning frame secures over a backing.

Floor cleaning system

The present invention relates to a floor cleaning tool. In one embodiment the floor cleaning tool comprises a backing and a handle. The backing comprises a first surface and a second surface. The handle is attached to the second surface of the backing apparatus. The backing has a generally triangular perimeter having a first edge, a second edge, and a third edge. A portion of the first edge is curved and a portion of the second edge is curved. The first edge and second edge meet at a leading point. The third edge is concave. The floor cleaning tool is capable of supporting a wipe.

Cleaning tool

A handle assembly for use with a fibrous cleaning pad. The handle assembly includes a generally rigid first member including a first insertable portion, and a handle portion with a first end of the handle portion fixed to a second end of the first insertable portion and a manually engageable part adjacent a second opposite end of the handle portion. The handle assembly also includes a second member including a second insertable portion, and an actuation portion having a first end fixed to a second end of the second insertable portion. A first end of the second insertable portion opposite the actuation portion is pivotally mounted on a first end of the first insertable portion opposite the handle portion for relative movement of the insertable portions by manual manipulation of the actuation portion between a diverging position with outer surfaces of the insertable portions diverging from their first ends, and an adjacent position with the outer surfaces of the insertable portions generally parallel. At least one of the insertable portions (and preferably both) has at least one barb projecting from its inner surface, and the other of the insertable portions has an opening aligned with that barb. The barb projects above the outer surface of the other of the insertable portions in the adjacent position of the insertable portions so that with the insertable portions in a slit in the cleaning pad the barb will engage the cleaning pad. The barb is essentially positioned between the outer surfaces of the insertable portions in their diverging position so that the insertable portions can move within the slit in the cleaning pad.

Cleaning device with disposable pad

A portable dispenser with which lengths of a sheet material may be manually dispensed from a supply roll of the sheet material. The dispenser has a frame including a bridging portion adapted to extend along a portion of the periphery of the roll of sheet material, and end wall portions fixed to the ends of the bridging portion and adapted to extend along the opposite end surfaces of the roll of sheet material on which the roll of sheet material is rotatably journaled. A resiliently flexible cantilevered portion of the frame has a proximal edge fixed to the bridging portion and has a sharp cutting edge along its opposite distal edge. A guard portion of the frame extends between its end wall portions and has an inner surface extending along the side of the cutting edge opposite the roll. The cantilevered portion is normally positioned in a retracted position at which the cutting edge is spaced from the roll of sheet material and is positioned adjacent the inner surface of the guard portion to restrict contact with the cutting edge by a person handling the dispenser such as to withdraw a length of sheet material from the dispenser. The cantilevered portion can be manually flexed by a person grasping the outer surface of the frame to move the cutting edge away from the inner surface of the guard portion to a cutting position at which sheet material being pulled from the roll can be engaged with the cutting edge to transversely sever the sheet material.

An elongated length of a single or double-sided stretch releasing adhesive tape that can be cut to a selected length with integral pull tabs for stretch removing the tape from a substrate. The stretch releasing adhesive tape can be provided as long strips or roll form. The elongated stretch releasing adhesive tape article includes an elongate length of stretch releasing adhesive tape defining a longitudinal axis. The stretch releasing adhesive tape has a first surface and a second non-adhesive surface. The first surface comprises one or more adhesive regions and one or more non-adhesive regions arranged along the longitudinal axis. At least a portion of the non-adhesive regions comprise a series of pull tabs arranged along the longitudinal axis that can be grasped in combination with the second non-adhesive surface by a user during stretch removal of the tape from an associated substrate.

Packaged unit for brushes

Brush

A brush including a laminate having a handle end portion adapted for manual engagement, and an opposite head end portion; and a plurality of rows of bristles having end portions adhered between adjacent plies in the head end portion of the laminate and projecting outwardly. The brush is formed from pieces of oriented polymeric film, portions of which are adhered to individual plies to be incorporated in the laminate and have portions projecting from the plies separated into bristles before the plies are laminated to form the brush. Lamination is done by driving moisture out of pasteboard layers coated with dried water activatable adhesive by exposure to radio freqeuncy energy which activates the adhesive to form the laminate.

Brush and its manufacturing method

A pen-like dispenser for applying rust converting liquid including a cap having an outer abrading surface adapted to scrape loose paint and rust from a surface to which the liquid is to be applied; and a liquid dispensing part including an elongate fluid reservoir having resiliently flexible walls, and a dispensing tip assembly. The tip assembly includes a valve member normally closing the tip assembly and having a tip projecting through an outlet passageway through the housing under the influence of a spring. The valve member may be moved to an open position by pressing its tip against a rusted substrate to afford outflow of the liquid, which flow can be controlled and aided by pressing inwardly on the flexible walls of the reservoir.

A telecommunication service wire shield connector stamped and formed from a sheet of metal and having a generally planar elongate base, a ground stud connection tongue extending from one end of the base, a strain relief adjacent the opposite end of the base and having teeth inclined toward the base for engaging the service wire sheath, and a shield connector between the connection tongue and the strain relief and having small teeth inclined toward the base for scraping the service wire shield upon insertion and making electrical connection to the shield.

A closable vessel including a main body portion and a hingeably affixed lid portion. A suction cup affixing structure is providing on either the lid or the back of the main body for removably affixing the vessel to a surface. When affixed the vessel presents its contents at an appropriate angle between the horizontal and the vertical for easy access by the user and to allow drainage of water. Drain holes accomplish drainage and provide ventilation to the contents when the vessel is closed. Alternate embodiments include use of partitions and a retaining bar for holding the contents. Further, a mirror may be provided for shaving or the like.
