DETAILED DESCRIPTION
[0077] 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.
[0078] Referring to FIG. 1, an aspect 100 of the invention may
involve a disposal bag with a frame. In an embodiment, the disposal
bag 100 comprises a flexible material 102. The flexible material
102 may be plastic, polymers, paper, coated paper, fabric, a
combination thereof, and the like. The plastic may comprise high
density polyethylene, low density polyethylene, polypropylene,
nylon, polylactic acid, a combination thereof, and the like. The
flexible material 102 may be of any suitable gauge or thickness.
The flexible material 102 may be biodegradable, chemical-resistant,
waterproof, flame retardant, radioactivity-resistant,
light-resistant, decorative, imprintable, and the like. The
flexible material 102 may be impermeable to fluids and gases, such
as for example, by being naturally impermeable, by applying a thin
impermeable or laminate sheet material to the surface of the paper
or other permeable material, by applying a waterproofing treatment
to the interior or the exterior of the material, and the like. The
flexible material 102 may be unstructured, as in FIG. 3 (302), or
structured. For example, the flexible material 102 may form a
substantially cylindrical shape with an unstructured bottom, as in
FIG. 3. In another example, the flexible material 102 may form a
box. The side walls 104 of the box may be constructed from a
flexible material 102, as described herein, that may sustain a
crease and be compliant enough to bend on moderate radii and return
to the original plane. The crease in the side walls 104 may fold
inwards or outwards.
[0079] 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.
[0080] Referring to FIG. 2, in an embodiment, the box may be
constructed in the manner of a standard flat bottom bag in its
lower portion. The line pattern 214 may be creased to preserve the
fold pattern once the flexible material is attached to the frame
112 in its three-dimensional form. The first lap joint 202 may
create a tube from the flat sheet and may be sealed so as to be
fluid and air impermeable. The bottom diagonal folds 218 may allow
the flat bottom to be created as in other known flat bottom bag
designs, first folding out in triangular double thickness ears on
two opposing sides, creating the plane indicated with a heavy line
from 204 to 208, with the central seam 210 overlapping by an amount
that provides a water and airtight joint. Then, the ears may be
folded under and attached to the square bottom surfaces. The top
edge of the bag may be folded internally on all four sides with the
corners double-folded over on each other on the diagonal lines 212
to form liquid/air tight corners. The third bonded seam may adhere
the folded-in bag top to the perimeter frame in a fluid and air
impermeable seal. Final folding on all of the other lines may
compact the bag to a flat pack configuration. In this embodiment,
the flat pattern for the box has a sealable valve 220 mounted in
the material.
[0081] 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.
[0082] 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.
[0083] 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 FIG. 3, oval, ellipsoidal,
circular, square as in FIG. 1, rectangular, polygonal, molded, as
in FIG. 4, and the like. The exact geometrical configuration of the
frame is not limiting for the present invention. The frame 112 may
be substantially flat. The frame 112 may be attached at an opening
of the bag along the inner surface of the bag, along an outer
surface of the bag, or a combination thereof. The frame 112 may
comprise a flexible material, a rigid material, or a semi-rigid
material, such as cardboard, plastic, or a planar material. The
rigid or semi-rigid material of the frame 112 may enable the bag to
be held in a substantially open configuration. The open
configuration may enable hands-free use of the disposal bag by
simply depositing the waste material into an open disposal bag and
either sealing the bag immediately or sealing the bag at some time
after the waste-making activity. For example, disposal of a soiled
baby diaper into the disposal bag may not require removal of both
hands from the baby. This feature may enable a user to dispose of
waste without contamination of their hands.
[0084] 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.
[0085] 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.
[0086] 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.
[0087] 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.
[0088] 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.
[0089] 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.
[0090] 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.
[0091] 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.
[0092] In an embodiment, the sealing facility may be mechanical.
Referring to FIG. 3, the sealing facility may be a tab 304. The
sealing facility may be a ball 802 or otherwise smooth geometric
solid. For example, a tab 304 or ball 802 on one side of the frame
112 may engage a tab 304 or ball 802 on the opposing side of the
frame 112 when opposing sides of the frame 112 are brought into
contact with one another to provide closure of the disposal bag.
The opposed tabs 304 or balls 802 may deflect past one another such
that when the deflected members may be past the centerline of both,
they may engage such that their surfaces create a pressure between
both that exerts a pressure on the two faces of the hinged top
frame 112 keeping them in tight engagement. The closure of the
disposal bag may be resealable by deflecting the tabs 304 or balls
802 past one another in the opposite direction to release the tabs'
304 or balls' 802 engagement. A single set or a plurality of
opposed tabs 304 or balls 802 may be disposed anywhere along the
perimeter of the frame 112. One or more sets of tabs 304 or balls
802 may be engaged to provide a resealable closure. In embodiments,
the tabs 304 or balls 802 may facilitate handling of the disposal
bag. The tabs 304 or balls 802 may be offset from one another such
that opposed tabs 304 may not engage one another. In this example,
the tabs 304 or balls 802 may not be intended for use as a sealing
facility but may still facilitate handling of the disposal bag. A
frame 112 with tabs 304 or balls 802 may be fabricated as a die- or
laser-cut piece from flat stock.
[0093] 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. In another embodiment, the interlocking feature
may comprise a snap on one side of the frame and a receiver on an
opposing side of the frame. When the interlocking features engage
2102, a constant pressure may be applied on a gasket surface
disposed along the frame 112 such that the gasket maintains an
airtight seal. It may be understood by one of skill in the art that
many different types of mechanical sealing facilities may be
utilized in the present invention.
[0094] In an embodiment, the sealing facility may be magnetic (not
shown). For example, a magnetically charged material may be
disposed on one side of the frame 112 and a magnetically compatible
material, such as iron, may be disposed on the opposing side of the
frame 112. As opposing sides of the frame 112 approach one another,
an attractive magnetic force may arise that may strengthen as
opposing sides of the frame 112 are brought into closer contact to
form a magnetically engaged configuration.
[0095] In an embodiment, the sealing facility may be thermal (not
shown). A thermoplastic film may be disposed on at least one side
of the frame 112. When opposing sides of the frame 112 are brought
into contact with one another and a heat sealing tool is used to
apply heat to the frame 112, the thermoplastic film may fuse to
form a seal.
[0096] In an embodiment, there may be a plurality of sealing
facilities on the frame 112. For example, a frame 112 may comprise
tabs for a temporary seal and a high-tack adhesive may be disposed
on the frame to provide a permanent seal. It may be understood by
one of skill in the art that many different types of sealing
facilities such as mechanical, molecular, chemical, electrical,
electromagnetic, nanofiber, nanostructure-based connections, and
the like may be used in the present invention. In any event, either
a temporary or a permanent seal formed by any sealing facility
described herein may be an airtight seal.
[0097] In an embodiment, a disposal bag may comprise a release
facility. The disposal bag may be vented by applying a pressure to
a sealed disposal bag to expel residual air through a release
facility. Preventing the expelled air from reentering the disposal
bag enables the waste to occupy a minimal volume for storage until
ultimate disposal of the disposal bag. The release facility may
comprise a vent tube 312 attached to the frame 112. The tube 312
may be straw-shaped, funnel-shaped, and the like. Upon sealing the
frame 112, the tube 312 may remain lightly trapped in the frame
112. After sealing and venting the disposal bag, the tube 312 may
be removed to allow an adhesive that may be adjacent to the vent
tube 312 to make contact and complete the seal. Alternatively, the
tube 312 may be plugged or sealed with a separate member. The tube
312 may be plugged or sealed with material that is part of the
frame 112 or bag or separate from the frame 112 or bag. The
material may be coated with an adhesive to facilitate a tight seal.
The release facility may comprise a channel 2002 in the surface of
at least one side of the frame 112, formed by the joining of the
opposing sides of the frame 112, formed in a gasket, and the like.
After sealing and venting the disposal bag, the channel 2002 may be
plugged 2004, sealed, self-sealed, and the like. The channel 2002
may be plugged 2004 or sealed with material that is part of the
frame 112, gasket, or bag or separate from the frame 112, gasket,
or bag. The material may be coated with an adhesive to facilitate a
tight seal. The release facility may comprise a vent, valve or a
hole 118. The vent, valve or hole 118 may be mounted anywhere in
the bag, such as in a portion close to the bottom of the bag, a
portion close to the frame 112, a portion of the bag midway between
the frame 112 and the bottom, and the like. The vent, valve or hole
118 may be formed into the material that may comprise the bag. The
vent, valve or hole 118 formed from the material comprising the bag
may protrude from the bag, as in FIG. 50. The vent, valve or hole
118 may be longer than it is wide which may facilitate collapse of
the channel as a result of normal atmospheric pressure being
greater than within the evacuated bag and inhibition of the entry
of air into an outside portion of the channel, as in FIG. 50. The
valve 118 may be a one-way valve or a two-way valve. After sealing
and venting the disposal bag, the vent, valve or hole 118 may be
plugged, sealed, self-sealed, and the like. The vent, valve or hole
118 may be plugged or sealed with material that is part of the
frame 112 or bag or separate from the frame 112 or bag. The
material may be coated with an adhesive to facilitate a tight seal.
In any event, the sealing material may further comprise a
microencapsulated adhesive that is activated by a pressure applied
during sealing. A porous element impregnated with a fragrance may
be placed inside a disposal bag such that air may pass over the
fragrant material as it is being vented, as in FIG. 50. In
embodiments, the release facility may have a minimum release
pressure, in that a minimum differential between the pressure
within and without the bag may be required for actuation to vent
air from the bag. In embodiments, the release facility may be
filled with a fluid substance that may form a seal except when the
bag may be pressurized. In any event, a plug may be tethered to the
frame, tethered to the bag, or may be a separate member. The plug
may be permanently shaped or may be shaped from malleable materials
that deform to fit the release facility.
[0098] In an embodiment, the disposal bag may comprise a gasket
310. The gasket 310 may facilitate formation of an airtight seal.
The gasket 310 may be any compressible or gap-filling material that
provides an airtight seal, such as foam, rubber, elastic, closed
cell foam, solid soft elastomeric material, void filling glue,
spring material, folded plastic or paper, and the like. The gasket
310 may be disposed on the surface of at least one side of a frame
112, on both sides of the frame 112, inside a sealing facility,
outside a sealing facility, and the like. The gasket 310 may
protrude just past the hinge 114 line such that when the frame 112
may be folded on a centerline, the gasket 310 may fill the small
void that may form at the hinge 114 line. An adhesive may be
disposed along the surface of the gasket 310. The adhesive may be
low-tack, high-tack, microencapsulated, and the like. The adhesive
may be protected by a peel away protective layer. An odor reducing
agent may be disposed in the gasket. An anti-microbial agent may be
disposed in the gasket. The gasket may be used in combination with
any of the disposal bag embodiments described herein.
[0099] In an embodiment, the disposal bag may comprise an internal
extension to the bag volume that may form a flap 902. The flap 902
may extend over a frame 904. 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.
[0100] 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.
[0101] 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. The anti-microbial 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
anti-microbial 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. The anti-microbial agent may
be embedded. The anti-microbial agent may be microencapsulated. The
anti-microbial agent may be activated by removal of a removable
film. For example, removal of a removable film protecting an
adhesive may release a microencapsulated anti-microbial agent and
expose the adhesive. The adhesive may be low-tack or high-tack.
[0102] Referring now to FIG. 11, the frame 112 of the disposal bag
may enable nesting 1102. For example, nesting may be where the
frame of a first disposal bag may provide support on its upper
surface for the frame of a second disposal bag when a second bag is
positioned on top of the first bag such that the lower surface of
the second bag's frame rests on the upper surface of the first
bag's frame and the second bag extends into the first bag. A
plurality of bags may be successively nested 1102 and the frames
112 may be successively stacked, one upon the other. The stack of
nested bags 1102 may be contained in a container 1104 for storing
and dispensing the bags. The container 1104 may facilitate a user
using and/or pulling out one bag at a time. For example, waste may
be placed into a top most nested bag 1102 while it is being
supported by the stacked frames beneath it. In an embodiment, a top
most nested bag 1102 may protect the frame 112 of a nested bag 1102
situated below it such that a peel-away adhesive protective layer
may not be required on each subsequently nested bag below a top
most nested bag 1102. The top surface of the frame 112 may be
coated with adhesive while the underside may be provided with a
non-stick backing surface that may protect the adhesive of the bag
frame 112 underneath but that may easily release the bag frame 112
above when a user may pick it up from a stack of nested bags
1102.
[0103] In an embodiment, the container 1104 may have an upper lip
portion that may be flanged to support a frame 112 of a disposal
bag. The container 1104 may be a cylinder, a canister, a box, a
dispenser, a tub, a can, a bucket, and the like. The container may
be made from plastic, cardboard, paper, polymers, metal, and the
like. The container 1104 may be round, square, rectangular, or any
suitable shape. The container 1104 may act as a holder to support a
bag while in use. The container 1104 may have a channel 1302 along
an edge that may expose an aligned row of nested bag handles. The
container 1104 may have a lid 1304. The lid 1304 may have a
corresponding channel 1308 that may cover the aligned row of
handles. The container 1104 may be sized to take up minimal space.
The container 1104 may be sized to be easily located near a site of
waste disposal, such as on a kitchen countertop, near a baby
changing table, and the like. A stack of nested bags 1102 may be
secured to one another and/or in the container 1104, such as for
during shipping or storage. For example, a peel tab 1202 disposed
along the vertical stack of bags 1204 at an outer perimeter of
their frames may be used to secure the stack. The peel tab 1202 may
comprise a low-tack adhesive, a wax/plastic binding, or other
substance that may allow the peel tab 1202 to be removed all at
once or gradually as the stack of bags is used. In another example,
a stripe of adhesive or wax/plastic binding may be disposed along
the vertical stack without a peel tab 1202. In another example, the
frames, tabs, or handles may have a slight interference feature
that engages one to the next and holds the stack assembled until
the individual selection and disengagement of the top most bag. It
may be understood by one of skill in the art that many different
types of stack securing methods, such as wax beads, plastic beads,
and the like, may be utilized in the present invention.
[0104] In an embodiment, once the initial supply of nested bags
1102 in the container is exhausted, the container 1104 may be
refilled with a new stack of nested bags. The refill stack of
nested bags may be contained in a refill pack 1314. The nested bags
in the refill pack 1314 may be compressed for shipping and/or
in-store display. The refill pack 1314 may be wrapped in a
disposable container. The refill stack 1314 of nested bags may be
secured to one another as described herein.
[0105] In an embodiment, the container 1104 may have a lower
portion that substantially holds the nested bags and an upper
portion that may act as a lid 1108. The lid 1108 may fit over a
container 1104. The lid 1108 may have a lip that engages with a lip
or indent on the container 1104. The attachment of the lid 1108 to
the lower container 1104 may be accomplished by a close fit of the
lid 1108 creating an outer sleeve fit over the inner similar
profile of the container 1104. The lid 1108 may be attached to the
container by a hinging mechanism. In an embodiment, the lid 1402
may swing open at a hinge 1404 to reveal the top most bag of a
stack of nested bags 1408. The lid 1108 may have a locking feature.
In an embodiment, the locking feature may be mating threads 1702,
as in FIG. 17. Mating threads 1702 may be formed in both the lid
1108 and the base of the container 1104 so that when the lid 1108
is positioned in a sleeve fit over the upward extending side wall
of the container 1104 and pushed into full engagement, the outward
protruding threads 1702 of the container 1104 will intercept the
inward protruding threads of the lid 1008 so that by twisting the
lid 1108 relative to the container 1104, the lid 1108 may be drawn
down into locked engagement with the container 1104. A further
downward twisting force on the lid 1108 against the top edge of the
container 1104 or against another designed spring feature within
the top or bottom of the container 1104 may cause an interference
engagement at the end of the thread. There may be a protrusion 1704
out of the line of the formed thread against a similar
counter-protrusion that provides a locking feature so that without
downward pressure the reverse twisting motion will not disengage
the thread. In another embodiment, the locking feature may be a
spring loaded snap lock engagement 1412. Spring loaded snap lock
engagement features 1412 may be formed in the base of the container
so that when the lid is closed in a sleeve fit over the upward
extending side wall of the base, an opening in the side wall of the
lid may accept the protruding snap lock button feature 1412 to lock
the lid in the closed position. The deflection of the material of
the side wall of the base may provide the spring pressure required
to engage the snap lock feature or another discrete physical spring
may be used. Opening the container may involve depressing a snap
lock button 1412 formed into the base wall of the container through
holes in the lid of the container, so that lifting the cover
disengages the lid from the base of the container. In any event,
the edges of the top frames of the nested bags may be exposed by an
opening in the side wall of the dispensing container and prior to
use this opening may be protected by a removable film or other
device that inhibits contamination of the bags.
[0106] In an embodiment, the lid 1108 may have a lid opening, as
seen in FIG. 14, such that the top most bag may be filled without
removal of the lid 1108. The lid opening may be created during
manufacturing, removal of a portion of the lid 1108 such as by
tearing along a perforation, peeling away a cover material, and the
like. The lid opening may expose only the bag opening while the
remainder of the lid 1108 may protect the frame from contamination.
After filling the top most disposal bag, the lid 1108 may be
opened, removed, or otherwise moved out of the way in order to
expose the filled bag such that the filled bag may be removed and
sealed for ultimate disposal. Once the bag containing the disposed
items may be removed, the next bag may be available for use. In an
embodiment, the lower portion of the container may not be sized to
allow the disposal bags to hang such that the bags may be filled
while supported in the container. The bags may need to be removed
one at a time prior to use. Alternatively, all of the bags may be
removed and placed into a larger container for storage and use as
described herein.
[0107] In an embodiment, the disposal system may comprise a
mounting system. For example, the mounting system may be a shaped
wire 1502 that may attach to an object, such as the rear of a car
seat, a wall, a crib, and the like. The wire 1502 may be shaped so
that the diameter of the shape may be smaller than the diameter of
a frame such that a frame may rest upon the wire. The bags may be
protected from contamination by a lid. For example, a mounting
device 1502 may encircle a container to snugly hold it in position
while an adjustable clamp 1504 firmly attaches the device to a
piece of furniture such as a baby changing table, a kitchen
counter, a work surface, a piece of furniture, and the like. Other
securement options may include hook-and-loop, adhesives, snaps,
suction cups, and the like. A fabric strap-like material,
optionally with further securing features or textures such as
zip-tie or hook-and-loop material may assist in securing the system
around an irregular or over-sized object. In any event, the
mounting system may be modular and may provide for both vertical
and horizontal clamp attachment in various forms. The encircling
portion of a mounting system may be common to several mounting
geometries, but may also be accomplished by a feature that may be
part of the container itself and therein a direct connection to the
clamping portion of the mounting system. In the case of mounting to
a horizontal element, there may be provided a U-shaped clamp body
that may accommodate a wide range of dimensions for a horizontal
edge feature and a clamping screw driven by a knob that may tighten
firmly onto that element. In the case of mounting to a vertical
element, there may be provided a U-shaped clamp body that may
accommodate a wide range of dimensions for a vertical feature and a
clamping screw driven by a knob that may tighten firmly onto that
element.
[0108] Referring now to FIG. 11, a waste disposal system 1100 may
comprise a disposal bag 1112, a container 1104, waste clean-up
articles 1118, and other materials that may facilitate disposal
and/or clean-up of waste. A dispenser for waste clean-up articles
1114 may be integrated into the disposal bag container 1104. For
example, a tissue dispenser 1114 may be integrated into the lid
1108 of a container 1104. The dispenser 1114 may be located on an
exterior surface of the lid 1108 or an interior surface of the lid
1108. The tissues 1118 may be wet, such as for a baby wipe, or dry.
The tissues 1118 may be used to wipe, wash, disinfect, cleanse, and
the like. When the tissue dispenser 1114 is mounted on an interior
surface of the lid, the dispenser 1114 may extend into a cavity
created by the stacked disposal bag openings 1102. The tissue
dispenser 1114 may have a removable lid with an orifice that may
permit the tissues 1118 to be sequentially pulled out one at a
time. The last pulled tissue 1118 may engage the next in line to
present an edge through the opening. The waste disposal system 1100
may be intended to match the number of tissues 1118 to the number
of disposal bags 1102 or may match the number of tissues 1118 and
bags 1102 in some other proportion. The tissue dispenser 1114 may
be refillable. Other materials that may be conveniently included in
the waste disposal system 100 may be one or more of hand
sanitizers, skin moisturizers, creams, lotions, rash medication,
and the like. These materials may be included in packets similar to
disposable condiment packets.
[0109] In an embodiment, the waste disposal system 1600 may be
integrated in or attached to a secondary waste container 1602. For
example, a secondary waste container lid 1603 may have an orifice
1608 of a diameter that is slightly smaller than the diameter of a
frame 112 such that a stack of nested bags 1102 may be inserted in
the orifice 1608 and the stacked frames may rest upon the secondary
waste container lid 1604. The nested bags 1102 may extend into the
secondary waste container 1602. In another example, a secondary
waste container lid 1604 may have an orifice 1608 that may
accommodate a container 1104 of nested bags 1102 as described
herein. The secondary waste container lid 1604 may also comprise an
orifice 1610 to insert a tissue dispenser, a bottle of lotion, a
tube of cream, and the like. The secondary waste container lid 1604
may have a built-in tissue dispenser that may be refillable. The
secondary waste container lid 1604 may have an opening 1612 to
insert trash, including sealed, waste-containing disposal bags
1614. The opening 1612 of the secondary waste container 1602 may
have a cover. The cover may be hinged. The cover may be opened by
any mechanical means such as a spring-loaded release mechanism, a
push, a pull, and the like. The cover may be opened by a motion
detection system. Auxiliary items, such as cleaning wipes, lotions,
creams, medications, and the like, may also be supported or
included in the secondary waste container. For example, the lid
1604 or top portion of the secondary waste container may be adapted
for supporting, holding, containing, or including the auxiliary
items and primary disposal bags. A larger, secondary disposal bag
may be contained within the secondary waste container 1602 for
receiving the smaller, primary disposal bags. The lid 1604 or top
portion of a secondary waste container 1602 with the features
described herein may be provided for mounting to an existing
secondary waste container, such as a trash can. Alternatively, a
complete system for disposal 1600 including a secondary waste
container with the features described herein may be provided.
[0110] In an embodiment, the disposal bag may be wearable. For
example, the disposal bag may be configured to be worn on a hand
1802. For example, the bag may be configured to be inside-out and a
user may insert 1804 a hand into the bag 1802. The user may then
grasp waste 1808 with the inside-out bag 1802 and then invert the
bag to remove it from their hand such that the waste remains in the
interior of the bag, as shown in FIGS. 69 and 70. The disposal bag
1802 may then be sealed as described herein.
[0111] In an embodiment, the disposal bag 1904 may be attached to a
diaper 1902. The disposal bag 1904 may be attached to a diaper 1902
on an exterior surface that may not touch skin. The disposal bag
1904 may be secured to the diaper 1902 with adhesive such as glue,
heat-activated polymer, double stick tape, microencapsulated
adhesive, and the like. The adhesive may be protected by a peel
away protective layer that may be peeled away to expose the
underlying adhesive and prepare the disposal bag 1904 for securing
to a diaper 1902. The disposal bag 1904 may be secured to the
diaper 1902 with a mechanical coupling such as snaps, zippers,
zip-tight style connections, spot welds, perforated seams,
stitching, hook-and-loop fastening patches, mechanical fasteners,
safety pins, and the like. A cleaning wipe or cloth or tissue may
be folded and inserted into the disposal bag 1904 to be used in
wiping a child when changing the diaper 1902. The used wipe may be
stuffed into the disposal bag 1904 along with the diaper 1902. Hand
cleaning cloths, sanitizing napkins, diaper rash creams,
moisturizers, ointments, scented fluids, and the like may be
carried along with or included in the package. For example, a skin
ointment may be provided in a single-use package and may be
attached to the diaper 1902 or contained within the disposal bag
1904. All of the used waste and packaging may be placed inside the
disposal bag 1904 and stored or discarded upon use. The disposal
bag 1904 may remain attached to the diaper 1902 and inverted onto
the used diaper 1902 for disposal. The disposal bag 1904 may be
completely detached from the diaper 1902 and the diaper 1902 may be
placed into the bag 1904 after it is detached. As described herein,
a user may invert the disposal bag 1904 and place it upon a hand in
order to reach through the bag 1904 and grasp the diaper 1902 and
waste. The diaper 1902 and waste may then be pulled into the bag
1904. In some embodiments, the disposal bag 1904 may be configured
to be or may be contained in a flat pack. The flat pack may be
accessed via tab or other graspable feature that may enable opening
of the flat pack to deploy the disposal bag 1904 to prepare it for
receiving the used diaper 1902 and waste. The bag 1904 may remain
attached to the diaper 1902. Deployment of the disposal bag 1904
may be similar to the unfurling of a parachute. The disposal bag
1904 stored in the flat pack may have a thin dimension and may be
stacked in large numbers in a container for distribution, sales,
on-site storage, and selection. The disposal bag 1904 may further
comprise a frame 112. The frame 112 may be sealed as described
herein. Alternatively, the disposal bag 1904 may be sealed by one
or more of a formed plastic zipper mechanism, an attached tie
material such as a strip of plastic, string, or fabric,
microencapsulated adhesive, an adhesive tab, a knot, and the
like.
[0112] In an embodiment, the disposed waste may be baby diapers,
incontinence products, feminine products, pet waste, kitchen waste,
household waste, garage or automotive waste, paint- or oil-
saturated rags, medical waste, biohazardous and hazardous material,
industrial shop waste, camping waste, waste generated in a car or
during travel, radioactive materials, other materials or waste with
an objectionable odor, and the like.
[0113] It may be appreciated by one of skill in the art that the
present invention may be applied in the storing, keeping, sealing,
preserving, collecting and the like of non-offensive materials, and
may in some cases be used to hold, seal, collect, and preserve
fresh goods, food, samples, and the like.
[0114] Many other systems, methods, object, features, and
advantages of the present invention will be appreciated. All such
systems, methods, object, features, and advantages are within the
scope of the present disclosure.
[0115] While the invention has been disclosed in connection with
certain preferred embodiments, those of ordinary skill in the art
may recognize other embodiments, and all such variations,
modifications, and substitutions may be intended to fall within the
scope of this disclosure. Thus, the invention may be to be
understood in the broadest sense allowable by law.
