  • Patent number: 11311099
    Abstract: A toilet brush system includes a toilet brush cleaner for cleaning a toilet brush of the type having an elongated handle with a proximal end and a distal end terminating in a brush head having a plurality of projecting brush bristles. The toilet brush cleaner comprises an elongated handle with a proximal end and a distal end that terminates in an open-ended sleeve sized to accommodate the distal end of the brush therein. The sleeve has a plurality of resilient, inwardly-projecting radial nubs, preferably made from an elastomeric material. In use, with the user holding the handle of the brush cleaner in one hand and the handle of the toilet brush in another hand, the user can repeatedly insert and withdraw the brush from the open sleeve, preferably while rotating the brush and within a flow of water in a toilet, to clean the brush head with the nubs.

  • Patent number: 9713390
    Abstract: An insertion device facilitates the insertion of a compressible pillow into a flexible pillowcase. A left edge of a resilient sheet includes a compression handle stem projecting away therefrom and terminating at a first compression handle. A right edge of the sheet includes a second compression handle projecting away therefrom. The sheet further includes a horizontal slot traversing therethrough, the slot sharing a common longitudinal axis with the compression handle stem. The resilient sheet when curved around itself, with the compression handle and the compression handle stem traversing the horizontal slot, form an enclosure into which the pillow is inserted. The compression handle is pulled away from the second compression handle to constrict the pillow, which, with the enclosure, is then easily inserted into the pillowcase.
