Definitions

  • the current sanitary napkin disposal bins used in public bath room facilities use paper, wax-coated paper, cellophane or plastic bags which are loosely placed in the bins.
  • the plastic bags even when placed over the upper edge of the bin, often slips down into the bin when the bag becomes filled. Paper and/or cellophane bags frequently collapse or fold inward, allowing sanitary products and the like to be disposed between the bag and a wall of the bin, thereby soiling the bin.
  • the term "refuse” refers to something that is discarded as worthless, useless, or used up. It is generally directed to rubbish, trash, garbage, and may include, among other thing, discarded sanitary products, kitchen waste, office waste, bathroom waste, household waste, yard and garden debris, and the like.
  • sanitary products include, but are not limited to, feminine napkins, tampons, colostomy bags, ileostomy bags, male incontinence pads, baby diapers, disposable training pants for children, adult incontinence products including pads, disposable underwear, and so forth.
  • fasteners means devices that fasten, join, connect, secure, hold, or clamp components together. Fasteners include, but are not limited to, screws, nuts and bolts, rivets, snap-fits, tacks, nails, loop fasteners, and interlocking male/female connectors, such as fishhook connectors, a fish hook connector includes a male portion with a protrusion on its circumference. Inserting the male portion into the female portion substantially permanently locks the two portions together.
  • the term “couple” includes, but is not limited to, joining, connecting, fastening, linking, or associating two things integrally or interstitially together.
  • the term “configure” or “configuration” means to design, arrange, set up, or shape with a view to specific applications or uses. For example; a military vehicle that was configured for rough terrain; configured the computer by setting the system's parameters.
  • the term “hinge” refers to a jointed or flexible device that connects and permits pivoting or turning of a part to a stationary component.
  • Hinges include, but are not limited to, metal pivotable connectors, such as those used to fasten a door to frame, and living hinges. Living hinges may be constructed from plastic and formed integrally between two members. A living hinge permits pivotable movement of one member in relation to another connected member.
  • the term “substantially” refers to something which is done to a great extent or degree; for example, “substantially covered” means that a thing is at least 95% covered.
  • alignment refers to the spatial property possessed by an arrangement or position of things in a straight line or in parallel lines.
  • orientation or “position” used interchangeably herein refer to the spatial property of a place where or way in which something is situated; for example, “the position of the hands on the clock.”

  • waste disposal units include, disposal units such as sanitary disposal units, residential bathroom waste bins, residential kitchen refuse bins, commercial office waste bins, garbage cans, and the like.
  • sanitary disposal unit refers to a unit provided on or in a wall or other structure of a public bathroom, that is, in the stall of each area containing a toilet, which is configured to receive sanitary products. These terms may be defined with additional language in the remaining portions of the specification.
  • Such a system would desirably be configured so that the disposal bag(s) did not slip down into the bin, resulting in refuse being deposited between the bag(s) and the wall of the bin.
  • such a system would provide a structure which would hold bags in place on the bin. Furthermore, it would be desirable of such a system provided a new empty disposal bag upon removal of the used disposal bag.

  • a plurality of bags 20 are provided attached to a frame 30 that is adapted to fit within a waste disposal unit.
  • the bags 20 are nested within each other with the innermost bag 21 open for waste to be disposed into. When the innermost bag 21 is filled, it is removed from the frame 30 and the next bag 22 is then available for disposal of refuse.
  • the frame 30 is adapted to fit within existing waste disposal units such that refuse does not fall between the frame 30 and the interior walls of the waste disposal unit.
  • Bags 20 are attached to the frame 30 and are individually removable when filled. Bags 20 are attached to the frame 30 by any means as is known in the art to attach bags 20 to the frame 30. For example, the bags 20 may be adhered to each other and the last bag adhered to the frame 30. Alternatively, the bags 20 may be attached to the frame 30 by fasteners 35, as shown in FIGS. 2 and 3, at various points about the frame 30. As another example, the bags may be thermally sealed to the frame 30. Such a thermal seal 36 is shown as the frame attachment in FIGS. 5 and 6. The bags 20 may alternatively be attached by any type of fastener that is appropriate for the materials used for the bags 20 and the frame 30. Any of such attachment methods or means may be used individually or in combination.

Typically, the frame 30 will be make from heavy paper cardstock or plastic, however, the frame 30 may be made from any material that will support the plurality of bags 20.
  • the frame 30 may be a single, unitary piece or it may made up of a plurality of individual laminate frames 41 that are plied together to form the frame 30.

  • the individual bags of the plurality of bags would each be attached to one of these individual laminate frames 41.
  • Each of these individual laminate frames 41 and individual bag assemblies could then be removed upon the filling of the individual bag.
  • frame extensions could extend the frame to, or beyond, the periphery of the waste disposal unit in which the assembly 10 is used.
  • Such end extensions 37 or side extension 38 could be added to the frame 30 to help ensure that refuse is directed into the bags 20, rather than between the frame 30 and the interior walls of the waste disposal unit.

Desirably, release strips 117 are removed and deposited in the bag, and the frame 30 is folded inward so that the upper surface 33 of the frame 30 adheres to itself to create a secure closure of the assembly. Additional functionality could be added with an odor control functionality that is provided by the bags 20.
  • Odor sorbing material could be disposed on the surface of the bags 20, within each of the bags 20, or within the bag substrate.
  • a sheet of cardboard or paperboard 107 may be treated with an odor sorbing material and included in or on the bags 20.
