Abstract: A floor mop for cleaning a floor. The floor mop includes a mop head and a handle pivotally connected to the mop head. A disposable cleaning sheet is attached by a minor portion adjacent one edge to a leading edge of the mop head, leaving a major portion of the cleaning sheet free. The mop may be passed over the floor with one side of the cleaning sheet presented for cleaning the floor. The mop head may then be inverted with the other side of the cleaning sheet presented for further cleaning of the floor.

Abstract: A blow molded box having (1) corner structures including hollow post-like supports against an outer polymeric sheet defining the corner, which supports are formed in inner polymeric sheets defining the inner surfaces of the intersecting walls at the corner; (2) dust resistant hinge that has central parts that engage when the box is opened or closed to retain the relative positions of those central parts against radial movement; and (3) locating portions on the sidewalls of the box that engage mating locating portions on the sidewalls of adjacent similar boxes to restrict slippage between the boxes and facilitate carrying a stack of the boxes, but which are resiliently flexible so that they do not greatly restrict removing the box from between adjacent boxes stored side by side on a shelf or hanging from a support member.

Abstract: Detachably secured to the ear piece of a hearing aid is a user-disposable sleeve comprising soft polymeric retarded recovery foam that can be compressed to be freely insertable into a person's ear canal and then allowed to recover to become wedged in the canal. The sleeve preferably includes a flexible, elongated plastic duct over which the foam fits, and the duct is formed with a screw thread of a rigid plastic which mates with a screw thread on the ear piece for easy attachment and removal. The external surface of the foam preferably is substantially cylindrical and can be formed with flutes to provide venting of the user's ear.

Abstract: A filing rack for a plurality of diskettes arranged in a front-to-back manner includes a plurality of slots for trapping the diskettes in an upright position and a plurality of ramps for supporting a portion of each diskette in an alternative resting position. The rack includes pairs of radius surfaces which translate a horizontal force applied to the front face of a diskette in its upright position into a force which lifts the diskette from its associated slot and permits the diskette to move into its alternative resting position.

Abstract: A dispensing assembly including an internally pressurized container of viscous liquid which may be dispensed through a hollow stem by deflecting the directing tube and stem to open a valve and cause liquid to flow out through an outlet opening in the directing tube. An overcap having a cavity adapted to receive the stem and directing tube releasably engages the container and has at least one, and preferably two, sockets along its inner surface for storing elongate hollow tapered application nozzles. The application nozzles have inlet ends adapted for engagement around the outlet opening on the directing tube so that the nozzles can be used to apply the liquid as it is discharged from the container.

Abstract: Fitted into the record-lockout opening of a recording tape cassette is a reusable record tab which comprises a body that blocks the opening and at least one resilient leg projecting from the body. The leg is bowed to press against an inner ramp of the cassette housing when the record tab is inserted into the opening, thus holding the record tab snugly in position. A small aperture through the external face of the body receives the point of a writing instrument for convenient removal of the record tab. FIGS. 1-4 show a reusable record tab for a VHS videotape cassette, and FIGS. 5-8 show a reusable record tab for a Betamax videotape cassette.

Abstract: A hand held dispenser for liner wound adhesive tape having walls that define a first cavity for storing a supply roll of liner wound tape, a second cavity with an inner wall surface which causes liner pushed into the second cavity to wind into a coil, an opening through which liner tape may be withdrawn from the dispenser, and path means for connecting the first cavity and the opening adapted to guide the tape being withdrawn through the opening, for connecting the cavities to guide the liner from the first cavity into the second cavity, and for separating the liner from the tape being withdrawn so that tape being withdrawn will propel the liner along the path means and into a coil in the second cavity.
