These and other systems, methods, objects, features, and advantages of the present invention will be apparent to those skilled in the art from the following detailed description of the preferred embodiment and the drawings. All documents mentioned herein are hereby incorporated in their entirety by reference.
The invention and the following detailed description of certain embodiments thereof may be understood by reference to the following figures:
Waste disposal methods and systems involve containment of the materials to be disposed of and may also involve containment of odor, use during waste-making activities, and use in an environmentally sound manner. An improvement that may be provided by the present invention relates to a waste disposal system comprising a disposal bag with a frame and related methods for inexpensive, compact, and convenient disposal of waste in an air-tight, odor-controlled, single-hand operable disposal bag. Waste may be placed in a disposal bag, which may be either free-standing or presented for use in a dispenser, and the frame may be folded at a hinge such that opposing sides of the frame are brought into contact with one another and the waste is sealed within the disposal bag. The frame may provide means for temporary and and/or permanent seal of the disposal bag in a substantially airtight and odor-free manner. The disposal bag may be stored for an extended period of time before final disposal in an odor-free manner.
Referring to
The box may collapse to a compact form by creasing and folding the flexible material 102. In an embodiment, the disposal bag may be free-standing. The material and thickness of the bag walls may in part result in the free-standing capability. The cutting and arrangement of the sides of the bags may in part result in the free-standing capability. For example, the bottom surface 108 of the bag may be flat permitting the bag to stand on a flat surface. In this example, the bag may form a box with side walls 104 such as those described herein, a substantially cylindrical structure with a flat bottom surface 108, and the like. The exact geometrical configuration of the bag is not limiting for the present invention. In an embodiment, the side walls 104 of the box may be pre-folded 110 to create a collapsing structure that, when folded flat, may conform to a square. Storage of the box may be facilitated by stacking or arranging the collapsed structures. For example, multiple folded squares may be placed alongside one another in a storage cube. Preparing the folded box for use may involve unfolding the box by straightening the folded sides to a substantially vertical configuration such that the bottom is substantially flat and the frame is substantially parallel to the bottom. The box may be used for disposal with or without a frame 112 as described herein.
Referring to
In an embodiment, the bag may be constructed from a continuous piece of material. Alternatively, the bag may be constructed from more than one piece of material. For example, the bag may be constructed from a single sheet of material that may have a cubic proportion. In another example, the bag is constructed from many pieces of material secured to one another through any conventional means. In an embodiment, the bay may be constructed using a sleeve-on-pipe manufacturing platform. The bag may be of any suitable size. In any event, the bag is constructed such that the material forms an opening in the bag.
In an embodiment, the bag may be clear, opaque, colored, patterned, and the like. The color may mark the contents within the disposal bag. The bag may include a written or graphical representation of the contents within the bag. For example, a marking of “Biohazard” with or without the recognized symbol for Biohazard may indicate that biohazardous content is contained within the disposal bag. In another example, the bag may be colored yellow and be marked “Radioactive Waste” with or without the recognized symbol for radioactive waste.
In an embodiment, the disposal bag may comprise a frame 112. The frame 112 may be associated with the bag at an opening in the bag. The frame 112 may be round, as in
In an embodiment, the frame 112 may be separately formed and attached to a bag by any method of attachment, including adhesive, thermal, heat sealing, physical, chemical, magnetic, ultrasonic welding, and the like. The frame 112 may be a single piece or formed from more than one part. The frame 112 may be molded from various polymer resins in a high-pressure injection molding process to include a suitable mechanical closure in the frame. The closure may comprise an interference locking system comprising one male and one female element that when pressed together may engage by mechanical spring interference to create an airtight seal. The closure may comprise a tongue 404 on one portion of the frame 112 that may move into engagement with a receiving cavity 408 on another portion of the frame 112 when a pressure may be applied to opposed sides of the frame once brought into close contact. The opening of the receiving cavity 408 may be of a smaller dimension than the tongue portion 404 and pressure may cause sufficient deformation at the entry to enable the tongue 404 to pass the opening lip and be fully enclosed by the cavity resulting in a tight mechanical engagement that may require significant force to disengage. The frame 112 may be supplemented by a gasket 412 or some other compressible or gap-filling material, as described herein. The gasket 412 may be disposed on the frame 112 such that it does not overlap with the interference locking system. For example, the gasket 412 may be disposed along an outer perimeter of the frame 112, along an inner perimeter of the frame 112, along an outer perimeter of one half of the frame 112 and along an inner perimeter of the opposing side of the frame 112, and the like. An alternative gasket solution may comprise a molded frame of diminishing dimension such that it may be relatively pliable at its outer surface 410 and may be formed to protrude toward the opposing feature 410 on an opposing side of the frame when in a closed configuration. When opposing sides of the frame may be brought into contact with one another, the compliant internal and external features 410 may deform one against the other creating an airtight and odor-proof seal along the perimeter of the frame 112.
In an embodiment, the frame 112 is integrally formed with the bag such as by using a chemical or manufacturing technique that forms a heavier frame 112 out of a portion of the bag near its opening. In an embodiment, the bag material may be extruded or otherwise formed from the heavier frame 112. For example, the technique may involve dipping the edge of the bag in a polymer liquid that may be heat or catalyst cured, a wax type material that may be applied and may be cooled, a paint type compound that may be air dried, a molding process such as insert injection molding wherein the frame 112 is formed to the edge of the material, and the like. There may be other materials and processes that may create a stiffness of the frame 112 and a smoothness of the frame surface that may facilitate the sealing function. For example, the top perimeter may be dipped or otherwise treated with a liquid or powder that may adhere to the edge inside and out, the application depth may be approximately that of the desired width of the frame. The liquid or powder may be capable of being formed, dried, and/or cured so that it may create a rigid surface that may incorporate the original material of the bag. Prior to forming, drying, and/or curing and while the material is still pliant, the material may be folded in any configuration so as to provide a frame 112 of suitable dimension. For example, a frame 502 may be formed by applying pressure on the inside and outside edge of the treated portion of the bag such that the material may be folded inward by a dimension desired for the width of the frame. The corners 504 may be folded to create an inward facing gusset that may be folded over upon itself so as to minimize the flat-folded dimension of the bag when stored or shipped. The corner joints may be filled in by chemical material or bag material so as to ensure a waterproof seal. A crease 508 may be formed as the frame 502 is created on the centerline creating a hinge point.
In an embodiment, the frame 112 may comprise a handle 604. The handle 604 may be constructed as part of the frame 112. The handles 604 on opposing sides of the frame 112 may be offset one to the other or may overlap. The handles 604 may facilitate opening and closing the disposal bag. The handle 604 may comprise a hole. The hole in the handle 604 may facilitate hanging or otherwise temporarily suspending or storing the disposal bag and its contents between uses. The handle 604 may be located on only one side of the frame 112. The handle 604 may facilitate alignment of one or more frames 112 with one another and/or in a container.
In an embodiment, the frame 112 may comprise a hinge 114. The hinge 114 may be formed in the frame 112 by a process that enables the rigid material to bend, such as by creasing, embossing, scoring, molding, perforating, stamping, cutting, breaking, and the like. The hinge 114 may extend partly or completely through the material of the frame. The hinge 114 may be located substantially at a centerline of a frame 112. The hinge 114 may be located at a bisecting point on a frame 112. The frame 112 may be able to fold at a hinge 114 such that one portion of the frame 112 may be brought in contact with another portion of the frame 112. Contact between opposing sides of the frame may be substantially uniform and airtight. When opposing sides of the frame are brought into contact with one another by pinching the hinge 114 or pulling up on opposing sides of the frame 112, the bag opening may be sealed. The opposing sides of the frame 112 may be brought into contact with one another in a single-handed operation or with two hands. In an example, if the disposal bag is in the form of a box, the side walls 104 may follow the motion of the frame 112 when it may be folded to close the bag opening.
In an embodiment, the frame 112 may comprise a sealing facility. Adhesive 702 may be used to form a temporary or permanent seal. For example, an adhesive 702 may be disposed along the surface of a frame. The adhesive 702 may be protected from accidental contact or contamination by a peel-away protective layer 704, a slippery interlayered separation sheet, by micro-encapsulation of the adhesive 702, by a two-part chemistry that is activated when adhesive layers on both sides of the frame 112 are brought into contact with one another, a combination thereof, and the like. For example, a peel-away protective layer 704 may be peeled away by grasping a portion of the layer not adherent to adhesive 702 and pulling, by physically separating the layer from the adhesive to 702 reveal a gap and continuing to extend that gap by pulling on the layer at the gap, and the like. A peel-away protective layer 704 may not be necessary for micro-encapsulated adhesives or adhesives with two-part chemistry. After exposure of the adhesive 702, opposing sides of the frame 112 may be brought in contact with one another such that the adhesive 702 on at least one side of the frame 112 makes contact with the opposing side of the frame 112 to form a seal. A pressure may be applied to form the seal.
In an embodiment, the adhesive 702 may be disposed along the top edge of a bag where a frame may not otherwise be attached. For example, the bag may be in the form of a box wherein the side walls of the box may be creased and are able to fold inwards or outwards. As described herein, a low-tack adhesive 708 may be disposed along one side of the bag from a mid-point fold line on one side around to the mid-point fold line on the other side. The opposite side may be coated with a high-tack adhesive 702 between these fold lines. The box may be sealed, either temporarily or permanently, with the side walls folded inward or the side walls folded outward such that there may be a single crease at an outer edge of the adhesive band.
In an embodiment, the adhesive 702 may be low-tack, high-tack, and the like. For example, a low-tack adhesive 708 may provide a temporary seal. The bag may be re-opened after sealing the frame with a low-tack adhesive 708. When the bag is re-opened, the adhesive 708 may be available for resealing the frame. The low-tack adhesive 708 may continue to provide a resealable closure until the tackiness of the adhesive 708 may wear off. In another example, a high-tack adhesive 702 may provide a permanent seal. A high-tack adhesive 702 may be gap filling. For example, a gap filling permanent adhesive may fill the hinge joint when the frame is sealed.
In an embodiment, the adhesive 702 may be disposed on the surface of one side of the frame 112, both sides of the frame 112, a portion of either side of the frame 112, and the like. For example, the adhesive 702 disposed on one side of the frame 112 may be low-tack 708 and the adhesive disposed on the opposing side of the frame may be high-tack 702. In this example, exposure of a low-tack adhesive 708 may provide a resealable closure of the disposal bag until a permanent seal is desired. The low-tack adhesive 708 may provide a resealable closure against the protective film 704 covering the high-tack adhesive 702 on the opposing side of the frame 112. When a permanent seal may be desired, a high-tack adhesive 702 on the opposing side of the frame 112 may be exposed. A permanent seal may be formed when the high-tack adhesive layer 702 may be brought in contact with the low-tack adhesives708 on the opposing side of the frame 112. The adhesion of the two different adhesives 702 to one another may fill the gaps of the sealed frame 112 and provide an airtight seal. For example, a portion of the adhesive 702 may be low-tack and a portion of the adhesive may be high-tack. A low-tack adhesive 708 may be disposed alongside a high-tack adhesive 702 on one or both sides of the frame 112. The adhesive layers may form stripes of adhesive 702 alongside one another. Multiple stripes of either adhesive 702 may be disposed along the surface of a frame 112. Each stripe of adhesive 702 may be protected as described herein. Exposure of a low-tack adhesive 708 may provide a resealable closure of the disposal bag until a permanent seal is desired. At that time, a high-tack adhesive 702 on the frame 112 may be exposed. A permanent seal may be formed when the high-tack adhesive layer 702 may be brought in contact with the opposing side of the frame 112.
In an embodiment, the sealing facility may be mechanical. Referring to
In another example, the sealing facility may be a snap fit mechanism. The entire perimeter edge of the frame may comprise a zipper edge wherein the zipper edge of one side of the frame may compatibly engage the zipper edge of the opposing side of the frame to form a seal. In another example, the snap fit mechanism is a clip affixed to the edge of the frame. When opposing sides of the frame are brought into contact with one another, the clip may engage the opposing side of the frame to form a seal. In another example, the snap fit mechanism is a hook and eye. When opposing sides of the frame are brought into contact with one another, a hook affixed to the edge of one side of the frame may engage an eye that may be constructed as part of the frame. The eye may be located within the perimeter of the frame or may extend beyond the perimeter of the frame. In embodiments, the sealing facility may be a clasp, a zipper, a snap, a gasket, an O-ring type closure, a hook-and-loop, a spring-locking hinge, an electrostatic potential, a combination thereof, and the like. In another example, the mechanical closure may comprise discrete interlocks 2102. In an embodiment, discrete interlocking features 2102 on opposing sides of the frame 112 may engage to form a mechanical seal. The interlocking feature 2102 may comprise a barb on one side of the frame 112 and a geometrically engaging receptor cavity on an opposing side of the frame 112. In another embodiment, the interlocking feature 2102 may comprise a ball on one side of the frame 112 and a detent on an opposing side of the frame 112. In another embodiment, the interlocking feature may comprise a snap hook on one side of the frame and a recessed edge on an opposing side of the frame.

The flap 902 may provide improved protection of the frame 904 from contamination during filling of the disposal bag. For example, an implement 1002 may be used to sweep material towards and into the bag without contaminating the frame 904. The flap 902 may be folded back into the bag prior to sealing the bag. The flap 902 may be attached to the frame 112 or may be integral to the bag.
In an embodiment, the disposal bag may comprise an odor reducing agent. The odor reducing agent may mitigate unpleasant odors associated with the disposed contents contained within the disposal bag. The odor reducing agent may provide a mood- or experience-enhancing effect, such as by providing a pleasant scent. The odor reducing agent may be a deodorant, odor neutralizer, air sanitizer, fragrance, scent, aroma, and the like. The odor reducing agent may be in the form of a liquid, an oil, a solid, a solid particle, a pellet, a capsule embedded in liquid, a powder, a talcum, and the like. The odor reducing agent may be disposed in one or more of an adhesive, a removable film, a frame, an exterior surface of the bag, an inner surface of the bag, a separate member, an attached member, a waterproofing treatment, and the like. For example, a fragrance may be disposed in a foil-wrapped pouch that may be separate from the disposal bag. The odor reducing agent may be embedded. The odor reducing agent may be microencapsulated. The odor reducing agent may be activated by removal of a removable film. For example, removal of a removable film protecting an adhesive may expose a microencapsulated fragrance and the adhesive. The fragrance may be released when pressure applied during the sealing of the frame breaks the encapsulation. Alternatively, a pressure may be directly applied to the adhesive to release a microencapsulated fragrance. The adhesive may be low-tack or high-tack.
In an embodiment, the disposal bag may comprise an anti-microbial agent. The anti-microbial agent may kill or inhibit the growth of microbes. The anti-microbial agent may prevent microbial contamination.
