Description
BACKGROUND
[0001] The present disclosure, in various embodiments, is directed
to waste containers, such as pet waste receptacles, trash
receptacles, diaper pails, compost containers, and medical waste
containers, and the like, with odor control. The waste containers
not only contain odors but also neutralize and reduce odors emitted
waste materials contained therein.
[0002] Enclosed waste containers are frequently used to dispose of
materials which emit generally continuous unpleasant and even
noxious odors. Many people have a limited means to dispose of
waste, i.e. once-weekly residential garbage pickup. To reduce costs
associated with garbage bags, extra garbage pickups, etc., waste
containers are typically used to receive many loads of waste prior
to being emptied. Between depositions of each load, the already
deposited contents tend to decay further, thus increasing the
foulness of the odors emitted.
[0003] This problem is particularly bad for biological waste
materials such as animal urine and feces, litter, diapers, medical
waste, and meat. However, even materials which do not emit
repugnant smells when first disposed of in a waste container tend
to become increasingly odorous after disposal. Waste containers are
often stored indoors where the smells are confined. Thus, the
smells tend to linger even after the covers of the waste containers
are closed and the people who dispose of the waste are not the only
people who are exposed the odor.
[0004] Therefore, it would be desirable to develop a waste
container which reduces or controls the odors emitted from the
waste contents of the container.
BRIEF DESCRIPTION
[0005] The present application discloses, in various embodiments,
waste containers. The waste containers comprise an enclosed waste
holding receptacle and an odor control dispenser. The odor control
dispenser releases an odor control composition comprising a
specific odor control agent when activated. The odor control agent
reacts with odor-generating molecules of the waste material to
neutralize and reduce odor produced thereby.
[0006] Disclosed in embodiments is a waste container comprising a
vessel body, a cover, and an odor control dispenser. The vessel
body includes an opening for receiving waste materials. The
removable cover operably encloses said opening. The odor control
dispenser selectively dispenses an odor control agent into the
vessel body upon activation. In certain embodiments, the odor
control dispenser may continuously release a vaporized odor control
composition and/or may release an odor control composition when the
cover is set in motion in relation to the vessel body.
[0007] The odor control dispenser may also release an odor control
composition upon activation of a trigger. In some embodiments, the
odor control composition may be vaporized or atomized upon
dispensing. The odor control composition reacts with the
odor-causing molecules produced by the waste materials to reduce
the odor.
[0008] In other embodiments, the waste container may further
include a second or further additional odor control dispensers. For
example, the second odor control dispenser may continuously release
a vaporized or atomized odor control composition and/or may release
an odor control composition when the cover is set in motion in
relation to the vessel body.
[0009] The vessel body and cover may be pivotally connected by a
hinge or may be slidably engaged.
[0010] The odor control dispenser contains a specific odor control
composition. The odor control composition does not mask the odor
produced by the waste material, but, instead reacts with the
odor-generating molecules to neutralize or reduce the odor produced
thereby.
[0011] The odor control agent may be a compound of Formula
(II):

DETAILED DESCRIPTION
[0054] A more complete understanding of the components, processes,
and apparatuses disclosed herein can be obtained by reference to
the accompanying drawings. These figures are merely schematic
representations based on convenience and the ease of demonstrating
the present disclosure, and are, therefore, not intended to
indicate relative size and dimensions of the devices or components
thereof and/or to define or limit the scope of the exemplary
embodiments.
[0055] Although specific terms are used in the following
description for the sake of clarity, these terms are intended to
refer only to the particular structure of the embodiments selected
for illustration in the drawings, and are not intended to define or
limit the scope of the disclosure. In the drawings and the
following description below, it is to be understood that like
numeric designations refer to components of like function.
[0056] The modifier "about" used in connection with a quantity is
inclusive of the stated value and has the meaning dictated by the
context (for example, it includes at least the degree of error
associated with the measurement of the particular quantity). When
used in the context of a range, the modifier "about" should also be
considered as disclosing the range defined by the absolute values
of the two endpoints. For example, the range of "from about 2 to
about 10" also discloses the range "from 2 to 10."
[0057] As used herein, the term "odor control agent" or "odor
control composition" refers to a chemical which reacts with
odor-causing molecules to reduce or eliminate odor. Odor control
agents are distinguished from deodorants and fragrances which mask
the odor but do not react with the odor-causing molecules.
[0058] The disclosure relates to waste containers comprising a
vessel body, a removable cover, and an odor control dispenser. The
vessel body includes an opening for receiving waste materials. The
cover operably encloses said opening. The odor control dispenser is
configured to selectively dispense an odor control composition
which comprises at least one odor control agent. Release of the
odor control composition is generally performed by spraying the
odor control composition out of the odor control dispenser. The
composition is released as a vapor or spray or is vaporized or
atomized after being sprayed. The waste containers of the present
disclosure are useful for neutralizing offensive odors emitted by
the waste.
[0059] FIG. 1 shows a first embodiment of a waste container 100 of
the present disclosure. The waste container 100 comprises a vessel
body 110 and a cover 120. A hinge 130 connects the cover 120 to the
vessel body 110. The waste container also comprises three odor
control dispensers 150, 160, and 170. Each dispenser draws an odor
control composition from a different odor control reservoir 151,
161, and 171. In the depicted embodiment, the first odor control
dispenser 150 is attached to the cover 120. This particular odor
control dispenser 150 continuously releases the odor control
composition contained in the reservoir 151. The odor control
dispenser which continuously releases the odor control composition
may alternatively be attached the interior of the vessel body. The
second odor control dispenser 160 draws an odor control composition
from reservoir 161 and is configured to release a portion of the
composition into the vessel body 110 when the cover 120 is set in
motion in relation to the vessel body 110, i.e. when the cover 120
is opened. The second odor control dispenser 160 may be configured
to release the odor control composition when the cover 120 makes
any movement with respect to the vessel body 110 or alternatively
may be configured to release the odor control composition when a
threshold angle between the cover 120 and the top of the vessel
body 110 is reached. In some embodiments, the amount of odor
control composition released may be a function of the angle between
the cover 120 and the top of the vessel body 110. For example, the
odor control dispenser 160 may release odor control composition at
a higher rate when the cover is barely open and little or no odor
control composition when the cover is fully open. The third odor
control dispenser 170 draws an odor control composition from
reservoir 171 and is configured to release the composition upon
activation of a trigger. The trigger may for example be a button
140 or a foot pedal 145. When the button 140 or the foot pedal 145
is pressed, the odor control dispenser releases a portion of the
odor control composition. An optional meter 180 displays the amount
of odor control composition remaining in each of the reservoirs
151, 161, and 171. Further optionally, the meter may produce a
signal when the amount of odor control composition falls below a
predetermined level. The signal may be a visual signal or an
auditory signal.
[0060] FIG. 2 illustrates a second embodiment of a waste container
200 of the present disclosure. The waste container 200 comprises a
vessel body 210 and a cover 220. The cover 220 slides across the
vessel body 210 via a rail 232. The waste container 200 comprises
an odor control dispenser 260 which draws an odor control
composition from a reservoir 261 and releases a portion of the odor
control composition when the cover 220 slides past a predetermined
point with respect to the vessel body 210. The depicted embodiment
also includes a second odor control dispenser 270 which draws odor
control composition from a second reservoir 271 and releases a
portion of the odor control composition when a trigger is
activated, e.g. when a button 240 or a foot pedal 245 is pressed.
The waste container 200 also includes a meter 280.
[0061] FIG. 3 depicts a third embodiment of a waste container 300
of the present disclosure. The waste container 300 includes a
vessel body 310 and a cover 320 defining a top portion of the waste
container 300. The cover 320 comprises a plurality of flexible
flaps 390. Waste may be placed in the vessel body 310 by pushing
the waste through the flexible flaps 390 in the cover 320. After
the waste material is placed into the vessel body 310, the flaps
return to a closed position. The flaps 390 may be comprised of
rubber or any other material which is capable of forming a seal
when the flaps 390 are in a first position, i.e. when there is no
pressure on the flaps 390, and forming an opening when pressure is
applied to the flaps 390. The waste container 300 further comprises
a first odor control dispenser 360 which draws an odor control
composition from a reservoir 361 and releases a portion of the odor
control composition when a waste material is being disposed of in
the vessel body 310. Alternatively, the odor control dispenser 360
may be configured to continuously release the odor control
composition. A second odor control dispenser 370 draws an odor
control composition from reservoir 371 and releases a portion of
the composition when a button 340 is pressed.
[0062] FIG. 4 portrays a fourth embodiment of a waste container 400
of the present disclosure. The waste container 400 comprises a
vessel body 410 and a cover 420 which are connected by a hinge 430.
The waste container 400 also comprises three odor control
dispensers 450, 460, and 470. The first odor control dispenser 450
continuously releases odor control composition. The second odor
control dispenser 460 releases odor control composition when the
cover 420 moves in relation to the vessel body 410. The third odor
control dispenser 470 releases odor control composition when a
button 440 is pressed or if a different trigger is activated. All
three of the odor control dispensers 450, 460, and 470 draw odor
control composition from a common reservoir 490. Odor control
dispensers 450 and 470 are attached to the reservoir 490 while odor
control reservoir 460 receives odor control composition through
tubing 495. The tubing may run within the sidewall of the vessel
body 410. Alternatively, all of the odor control dispensers may be
directly attached to the reservoir or all of the odor control
dispensers may receive odor control composition from the reservoir
via tubes. Meter 480 displays the amount of odor control
composition remaining with the reservoir 490 and optionally
provides a signal when the amount falls below a predetermined
level.
[0063] FIG. 5 displays a fifth embodiment of a waste container 500
of the present disclosure. The waste container 500 comprises a
vessel body 510 and a cover 520 which may be connected at a hinge
(not shown). The waste container 500 also includes a foot pedal 545
which may be pressed to open the cover 520. The cover 520 includes
a cartridge holder 599 for receiving a cartridge 597. The cartridge
597 includes an internal reservoir (not shown) which holds an odor
control composition. A button 580 atop the cartridge 597 acts as a
trigger for the release of a portion of the odor control
composition from the reservoir. The cartridge 597 may be
replaceable and/or refillable. The combination of the button 580
and the foot pedal 545 allow a user to open the vessel body and
distribute the odor control composition without using two hands. In
other words, the user can carry a waste bag to be disposed of in
one hand while operating the waste container 500.
[0064] FIGS. 6-8 present a sixth embodiment of a waste container
600 of the present disclosure. The waste container comprises a
vessel body 610, a cover 620, and an odor control dispenser 650.
The waste container may have a height of about 30 inches. The cover
620 includes an attachment portion 622 and a lid portion 624. The
attachment portion 622 may have an outer diameter of about 15
inches. The lid portion 624 may have a diameter of about 5 inches.
The lid portion 624 is pivotally connected to the attachment
portion 622 by a hinge 625. The hinge 625 may comprise a torsion
spring to automatically open the lid 624. The torsion spring may be
configured to open the lid at a relatively slow rate to reduce the
dispersal of odors. The attachment portion 622 may be connected to
the vessel body 610 by snapping on. For example, the attachment
portion 622 may comprise a receiving member 626 which receives an
outer lip 613 of the vessel body 610. A snapping configuration
allows plastic bags to be easily inserted and removed from the
waste container 600. The odor control dispenser 650 can be a
cartridge which can be attached to the cover 620. The cartridge 650
may be removable and/or refillable. The cartridge may generally be
any shape which fits in a corresponding waste container.
Non-limiting examples include rectangular, circular, and
ring-shaped cartridges. The cartridge may have a capacity of about
1/2 cup.
[0065] The cartridge 650 may be activated by a button 627 located
on an inner lip 623 of the attachment portion 620. Activation may
occur when the lid 624 is pushed down. This may also cause the
torsion spring to open the lid.
[0066] Some of the waste containers of the exemplary embodiments
include multiple odor control dispensers. However, these waste
containers may also include only one dispenser. When one dispenser
is used, the dispenser may be triggered to release odor control
composition by one or more triggers. For example, the single
dispenser may release the odor control composition when the cover
is moved with respect to the vessel body and/or when a button or
foot pedal is pressed.
[0067] The single dispenser may also be configured to continuously
release a baseline amount of odor control composition in some
embodiments. The activation of triggers then increases the rate at
which the odor control composition is released.
[0068] In embodiments, pressing the button or foot pedal may also
cause the cover to open. The waste container may be configured such
that the opening of the cover and the release of odor control
composition are not simultaneous. For example, after a user presses
the button or foot pedal, the odor control composition may be
released immediately. However, the opening of the cover may be
delayed so that the odor control composition has more time to
neutralize odors prior to the user being exposed to smells from
inside the vessel body.
[0069] Release of the odor control composition may be actuated
mechanically via opening and closing of the cover, electronically
via an electronic switch on the cover, or by a light-sensitive
which. During opening of the cover or lid, an increasing amount of
light may reach the switch whereas a decreasing amount of light may
reach the switch during closing.
[0070] When a single reservoir is used to feed multiple odor
control dispensers, the composition released by each odor control
dispenser will be the same. In some embodiments, wherein multiple
odor control dispensers are used, the compositions released may
differ between dispensers.
[0071] The odor control composition relates to specific chemicals
which react with odor-causing molecules of the waste material. The
composition may comprise from about 0.1 to about 5 wt % odor
control agents.
[0072] In more particular embodiments, the odor control agent is a
chloramine. Chloramines are suitable odor control agents based on
the ability to release an active Cl.sup.+ ion when needed on
demand, immediately after which, an active aromatic sulfo nitrene
companion ion is generated. The Cl.sup.+ ion starts the conversion
process of the odor molecule and is immediately assisted by the
companion aromatic sulfo nitrene which completes the conversion
process. Specific chloramines include chloramine T, chloramine B,
and CH-BENZ.
[0073] Chloramine T, illustrated below, is the common name for
N-chloro-4-methyl benzenesulfonamide.
##STR00004##
Chloramine T as used herein may also refer to a salt, e.g. as a
sodium salt. Chloramine T may also be hydrated. For example, the
chloramine T may be a tri-hydrated sodium salt as shown in Formula
(I)
##STR00005##
[0074] Chloramine B, illustrated below, is the common name for
N-chlorobenzenesulfonamide sodium salt.
##STR00006##
Chloramine B may also be hydrated.
[0075] CH-BENZ, illustrated below, refers to
N-chloro-4-carboxybenzenesulfonamide.
##STR00007##
[0076] More generally, the odor control agent may comprise a halo
active aromatic sulfonamide organic compound. The halo active
aromatic sulfonamide compounds are in the low to no toxicity range
according to Environmental Protection Agency (EPA) standards. The
low toxicity of the compounds makes the compounds attractive for
use in human and animal environments. The halo active aromatic
sulfonamide compounds are in accordance with the following Formulas
(II) to (V).
##STR00008##
wherein X is a halogen, R.sub.3 is hydrogen, methyl, or COOM,
R.sub.1, R.sub.2, R.sub.4, R.sub.5 are independently hydrogen,
COON, derivatized COON, an ester or alkylated amide, COOM, CN,
NO.sub.2, SO.sub.3H or derivatized SO.sub.3R, a halogen, a
substituted or unsubstituted phenyl group, a sulfonamide, a
halosulfonamide, a straight or branched aliphatic moiety from
C.sub.1 to C.sub.12, wherein, the same straight or branched
aliphatic moiety may contain substitution at one or more of the
aliphatic hydrogens, R.sub.1, R.sub.2, R.sub.4 and R.sub.5 are
other than all hydrogen, R is hydrogen or substituted or
unsubstituted C.sub.1-C.sub.12 alkyl, and M is an alkali or
alkaline earth metal.
[0077] Additional compounds which are useful odor control agents
are in accordance with Formula (III):
##STR00009##
wherein X is a halogen, R.sub.1, R.sub.2, R.sub.4, R.sub.5 are
independently hydrogen, COOH, derivatized COOH, an ester or
alkylated amide, COOM, CN, NO.sub.2, SO.sub.3H or derivatized
SO.sub.3R, a halogen, a substituted or unsubstituted phenyl group,
a sulfonamide, a halosulfonamide, a straight or branched aliphatic
moiety from C.sub.1 to C.sub.12, wherein the same straight or
branched aliphatic moiety may contain substitution at one or more
of the aliphatic hydrogens, R.sub.3 is an organic derivatized COOH,
an ester or alkylated amide, CN, NO.sub.2, SO.sub.3H or derivatized
SO.sub.3R, a halogen, a substituted or unsubstituted phenyl group,
a sulfonamide, a halosulfonamide, a straight or branched aliphatic
moiety from C.sub.2 to C.sub.12, wherein the same straight or
branched aliphatic moiety may contain substitution at one or more
of the aliphatic hydrogens, and M is an alkali or alkaline earth
metal.
[0078] Other compounds which are useful as odor control agents are
as per Formula (IV):
##STR00010##
wherein X is a halogen, R.sub.1, R.sub.2, R.sub.4, R.sub.5 are
hydrogen, R.sub.3 is hydrogen, methyl, or COOM, and M is either
potassium, rubidium, cesium, lithium or an alkaline earth
metal.
[0079] Other compounds which can be used as odor control agents are
in accordance with Formula (V):
##STR00011##
wherein X is bromine, fluorine, or iodine, R.sub.1, R.sub.2,
R.sub.4, R.sub.5 are hydrogen, R.sub.3 is hydrogen, methyl, or
COOM, and M is an alkali or alkaline earth metal.
[0080] Compounds of Formulas (II)-(V) may or may not be hydrated (n
H.sub.2O), but are generally isolated as a trihydrate (where
n=3).
[0081] The compounds of Formulas (II)-(V) are very soluble in
water. This property allows for easy compounding of odor control
compositions and allows high percentages of the compounds to be
formulated into the useful solution products.
[0082] Further the compounds of Formulas (II)-(V) have minimal
bleach odor. This property again is highly advantageous, because,
formulations with strong bleach odor are undesirable in most
applications.
[0083] The activity of the aromatic chlorosulfonamido group of the
compounds of Formulas (II)-(V) is regulated by the selection of
specific "R" groups. "R" groups adjacent to the chlorosulfonamido
group (R.sub.1 and R.sub.5) can cause steric effects and therefore
change activity and/or cause stability changes on the
chlorosulfonamido group. In addition the various "R" groups can be
effected differently. Specific increases or decreases in activity
and, stability may be noted. The usefulness of specific aromatic
chlorosulfonamido groups may be affected by their different and
unique inductive or resonance effects.
[0084] Bleach is commonly used as a source of Cl+ cations which are
effective as deodorizers. The term "Cl+" refers to the fact that
the chlorine atom has a +1 formal charge in a hypochlorite ion,
ClO.sup.-, which is the form taken by the chlorine atom when
dissociated from the sulfonamide compound. A chlorine atom is
generally considered to have a charge of 1.sup.-. Reference to the
chlorine atom as having a +1 or 1.sup.- charge may be used in this
application interchangeably because this terminology has no effect
on the compound itself or its use. Because of the problems
associated with the use of bleach, i.e. the discoloration of the
substrate, and its heavy non discrete oxidizing power, it is
generally not suitable for use as a deodorizer. In addition the Cl+
cation which is produced by bleach is much more ionic and non
discrete in its reactions when compared to the Cl+ cation produced
by the compounds of Formulas (II)-(V). Further, as the compounds of
Formulas (II-V) liberate the Cl+ ion, a companion ion an aromatic
sulfo nitrene, is released which also is intimately involved in a
reaction to convert the odorous molecule to a non-odorous state.
That is when compared to the Cl+ cation produced by bleach, the Cl+
cation produced by the compounds of Formulas (II)-(V) is much more
covalent and less ionic and therefore is very selective in its
initial reaction as a deodorizer, hence, it will attack the odor
source and not the substrate. As a result of this covalence the
bleaching side effects resulting from the Cl+ cation produced by
the compounds of Formulas (II)-(V) do not cause the bleaching
problems produced by bleach. Therefore, the Cl+ cation produced by
the compounds of Formulas (II)-(V) can be used to deodorize as they
do not have side effects such as strong bleach smell etc. Generally
it could be said that the compounds of Formulas (II)-(V) are more
stable than bleach and have a higher selectivity as a Cl+ source as
compared to the Cl+ cation produced by bleach. In addition, the
N-halogenated aromatic sulfonamide when activated by an attack on
an odorous molecule by its Cl+, further produces an active aromatic
sulfo nitrene which also modifies the odor causing molecule in such
a manner that it is no longer an odorous molecule.
[0085] In summary, compared to bleach the compounds of Formulas
(II)-(V) are superior deodorizing agents because they are more
selective, more covalent Cl+ and because the backbone companion
ion, the aromatic sulfo nitrene, remaining after the Cl+ cation is
released from the compounds of Formulas (II)-(V), is itself very
selective but very active and immediately contributes its odor
controlling power. This backbone companion ion has the ability to
further react with the odor containing molecule thereby permanently
removing it as a potential source of odor. In contrast the chemical
moiety which remains after the Cl+ cation is removed from bleach
has no ability to react with odor causing molecules.
[0086] The odor control agent may also comprise a polymer. Halo
active aromatic sulfonamide polymers in particular exhibit little
or no toxicity according to EPA standards. The polymer may be of
