FIELD OF THE INVENTION
[0002] The present invention generally relates to assemblies for
storing and dispensing materials. More particularly, the invention
relates to assemblies for sealing material within a container and
for controllably dispensing material from the container, to systems
including the assemblies, and to methods of using and forming the
assemblies and systems.
BACKGROUND OF THE INVENTION
[0003] Many containers for storing and dispensing material are
known. For example, sealed containers formed of resilient material,
such as foil or plastic, are known. Material is often dispensed
from such containers by rupturing (e.g., tearing) a portion of the
container and squeezing a portion of the container to cause the
material to flow through the ruptured portion of the container.
[0004] Although these containers work well for several
applications, they may be deficient for use in some applications.
For example, the rupturing or tearing of the container can be
unpredictable, which leads to an unpredictable opening in the
container. As a result, flow and placement of material extruded
from the container may be unpredictable and/or difficult to
control.
[0005] Accordingly, improved containers and systems including the
containers are desired.
SUMMARY OF THE INVENTION
[0006] The present invention provides an improved assembly, system
including one or more assemblies, and methods of using and forming

DETAILED DESCRIPTION
[0026] The present invention provides an improved assembly for
containing and dispensing material and a system including the
assembly. As described in more detail below, the assembly provides
a convenient, easy-to-use container and applicator for use with a
variety of materials and applications. For example, the system can
be used to contain and dispense oral care materials to a gum/tooth
interface and surrounding areas within an oral cavity.
[0027] FIG. 1 and FIG. 2 illustrate a system 100, including an
assembly or container 102 and a material or composition 104, in
accordance with various embodiments of the present invention.
System 100 can be used to dispense material 104, such as liquid, a
semi liquid, or dry granule materials, to a desired location using
assembly 102. In addition, system 100 can provide protection to
material 104 from, for example, moisture, ultraviolet (UV)
radiation, and the like, during storage.
[0028] Assembly 102 includes a vessel or expulsion portion 106 and
an elongated spout or applicator portion 108. As discussed in more
detail below, vessel portion 106 and spout portion 108 may be
separately formed and coupled together to form assembly 102.
Separately forming vessel portion 106 and spout portion 108 may
facilitate filling assembly 102 with material 104, facilitate
manufacture of the assembly, and may also facilitate dispensing
material 104 to a desired location.
[0029] Vessel portion 106 may be formed of a variety of resilient
materials, which preferably retain and return to their original
structure when not under pressure, such as various types of
plastics, foils, and the like. In accordance with one embodiment,
vessel portion 106 is formed of thermoplastic resin, such as
low-density polyethylene. Other thermoplastic materials suitable
for use for vessel portion 106 may include high density
polyethylene, medium density polyethylene, linear low density
polyethylene, polyvinyl chloride, K resin, polyethylene
terephthalate and copolyesters, polypropylene, surlyn, silicones
and other thermoplastics. Portion 106 may be opaque, transparent,
or semitransparent. An advantage of forming vessel portion 106 of
transparent or semitransparent material is that an amount of
material 104 within vessel portion 106 can be ascertained when the
portion is formed of such material. Material used to form vessel
portion 106 may also include UV protection additives, colorants, or
the like. When used to dispense food, drugs, supplements, or the
like, vessel portion 106 is preferably formed of FDA-approved
material.
[0030] In accordance with various embodiments of the invention,
vessel portion 106 includes a resilient vial 110, a neck 112 (see
FIG. 4), and an optional transition portion 114. Resilient vial 110
acts as a reservoir for material 104 and also facilitates expulsion
of material from assembly 102 when pressure is applied to an
external surface of vial 110. Neck 112 is configured to couple to
spout portion 108, and transition portion 114 connects vial 110 to
neck 112.
[0031] Although illustrated as substantially tubular, with a
semispherical, sealed end 116, resilient vial 110 may be of any
suitable shape. For example, vial 110 may be pyramidal, cone
shaped, fluted, or have a rectangular cross section. Similarly, end
portion 116 may be of any suitable shape, such as linear (e.g., a
crimped end) or the like. In general, preferred shapes of vial 110
conserve material used to form the vial, allow for easy dispensing
of material 104, are easy to produce, and produce relatively little
scrap during production. Further, a size of vial 110 may be
selected for a particular application. For example, a size of vial
110 may be selected for application of a single dose of
material.
[0032] Transition section 114 is the portion of vessel portion 106
between vial 110 and neck 112. Transition portion 114 may be of any
suitable shape such as frustro-conical, fluted, and the like.
[0033] Although not illustrated, systems in accordance with various
embodiments of the invention may include tamper-resistant features.
For example, system 100 may include a seal formed over neck 112,
using, for example plastic or foil glued to or otherwise adhered to
a top portion of neck 112. Alternatively, after spout portion 108
is attached to vessel portion 106, the two portions may be fused
together using heat sealing and/or adhesive techniques.
[0034] Spout portion 108 includes a cap 118 and a spout 120, which
has an end portion 122. As described in more detail below, cap 118
is configured to attach to neck 112 of vessel portion 106.
[0035] Cap 118 may be configured in any suitable shape that
sealably couples to neck 112. In accordance with the illustrated
embodiment, cap 118 fits over an exterior portion of neck 112.
However, neck 112 and cap 118 may alternatively be configured such
that cap 118 sealably attaches to an interior portion of neck
112.
[0036] An example of cap 118 includes a circular cross section;
however, cap 118 may suitably be configured in other shapes, such
as, for example, having a square, rectangular, or triangular cross
section. Cap 18 may also include a decorative skirt on an exterior
portion 119.
[0037] Spout 120 is configured to facilitate placement and
controlled flow of material dispensed from system 100. Spout 120
may be substantially cylindrical, as illustrated. Alternatively,
spout 120 may have a square, rectangular, ellipse, or other
cross-section configuration. Spout 120 may also include a weakened
section 126, which may be formed, for example, by scaring a portion
of spout 120. Weakened section 126 may facilitate rupturing spout
120 at weakened section 126, which in turn allows for a predicable
cross section of spout 120 and thus a relatively predictable flow
of material dispense from system 100. Having a substantially
constant cross-section of spout 120, as illustrated, also makes the
flow more predictable, even if spout 120 is ruptured away from
weakened area 126.
[0038] As illustrated, spout 120 may form an angle relative to an
axis, A-A, illustrated in FIG. 2. In accordance with various
embodiments of the invention, spout 120 forms an angle of about 0
degrees to about 80 degrees from axis A-A, preferably about 0
degrees to about 55 degrees, and more preferably about 40 degrees
to about 55 degrees. In accordance with one specific example, spout
120 forms an angle of about 48 degrees relative to axis A-A.
[0039] End portion 122 forms a sealed end at one end of spout 120.
In accordance with various embodiments of the invention, end
portion 122 is flat and wider than an interior portion 124 of spout
120. Having end portion 120 wider than spout 120 allows a user to
grip end 122 to, for example, tear spout 120 at weakened section
126. However, end 122 may be alternatively configured as, for
example, a semisphere or other suitable shape.
[0040] Spout portion 108 may be formed using a variety of
materials, such as any of the materials described above in
connection with vessel portion 106. Examples of materials include
polypropylene, high density prolethylene, low density polyethylene,
medium density polyethylene, linear low density polyethylene,
impact polystyrene, surlyn, silicone, K resin, nylon, copolyester,
and similar materials. However, because spout portion 108 may be
formed separately from vessel portion 106, it need not be formed of
the same material.
[0041] In accordance with one embodiment of the invention, vessel
portion 106 and spout portion 108 are configured to sealably (and
optionally rotatably) couple to each other. In accordance with
various aspects of this embodiment, one of neck 112 and cap 118
includes a protrusion and the other of neck 112 and cap 118
includes a recess to receive the protrusion, such that the
protrusion and recess hold vessel portion 102 and spout portion 108
together, while optionally allowing the two portions to rotate
about an axis, with respect to each other. In accordance with
another embodiment of the invention, neck 112 and cap 118 are
configured to allow vessel portion 106 and spout portion 108 to be
detachably coupled to each other. In this case, neck 112 and cap
118 may be snap-fit together as described above, or one of neck 112
and cap 118 may include an external threaded portion and the other
of neck and 112 and cap 118 may include an internal portion (e.g.,
a threaded portion) to threadably receive the other portion, such
that neck 112 and cap 118 form a seal when the two parts are
threadably engaged. In accordance with yet other embodiments, neck
portion 112 and cap 118 may engage using lug or interference-fit
technology.
[0042] FIG. 3 and FIG. 4 respectfully illustrate spout portion 108
and vessel portion 106, in greater detail, in accordance with
various embodiments of the invention.
[0043] FIG. 3 illustrates a cross-sectional view of spout portion
108. Portion 108 is configured such that an interior surface 302 of
spout 120 is fluidly coupled to an interior portion 304 of cap 118.
In the illustrated embodiment, first end 306 of spout 120 is
fluidly coupled to cap 118 and forms an angle relative to axis A-A,
and second distal end 122 is along an axis B-B from first end
306.
[0044] In the illustrated embodiment, cap 118 includes a sealing
flange 308 in the form of a protruding ring about interior surface
304 of cap 118, and a protrusion 310, also in the form of a ring on
interior surface 304. Flange 308 is located near an upper surface
312 of interior surface 304 of cap 118 and is preferably angled
away from surface 312 of cap 118, such that when spout portion 108
is coupled to vessel portion 106, flange 308 forms a seal with a
top 402 (FIG. 4) of neck 112. In accordance with an alternate
embodiment of the invention, cap 118 and neck 112 may be sealably
connected using a valve seal.
[0045] Protrusion 310 is configured to fit within a recess 404
within neck 112. In the illustrated embodiment, protrusion 310 and
recess 404 are configured, such that spout portion 108 and vessel
portion 106 are sealably and (optionally) rotatably coupled
together--e.g., in a snap-fit manner. FIG. 5 illustrates an
alternative configuration of assembly 102, in which neck 112
includes a protrusion 502, which is received by a recess 504 within
cap 118.
[0046] As illustrated in FIGS. 1, 4, and 5, neck 112 of vessel
portion 106 also includes a capping ring 132. Capping ring 132
allows production equipment to hold and support vessel portion 106
during production, reduces tampering with system 100 by making it
more difficult to remove spout portion 108 from vessel portion 106,
and may act as a stop when spout portion 108 is attached to vessel
portion 106, by preventing spout portion 106 from moving too far
down neck 112 of vessel portion 106.
[0047] In accordance with additional embodiments of the invention,
system 100 is formed by separately forming vessel portion 106 and
spout portion 108, filling vessel portion 106 with material 104,
and attaching spout portion 108 to vessel portion 106. Vessel
portion 106 may be formed using a variety of techniques. By way of
particular examples, vessel portion 106 is formed using
blow-molding, injection-molding techniques, such that vessel
portion 104 includes a relatively thin-walled vial section 110 and
a relatively thick-walled neck 112. Vessel portion may
alternatively be formed using extrusion blow-molding
techniques.
[0048] Spout portion 108 can also be formed using a variety of
techniques. By way of one example, spout portion 108 is formed
using injection-molding techniques, such that cap 118 and elongated
spout 120 are formed in a single process step. After portion 108 is
formed, a portion of spout 120 is sealed to form sealed end 122 and
another portion of spout 120 is scared to form weakened section
126. Sealed end 122 may be formed, for example, using heat,
ultrasonic waves, a laser, or any combination of such
techniques.
[0049] Once vessel portion 106 and/or spout portion 108 are formed,
information may be printed on the respective portion, using ink
jet, silk screen, paper label, a shrink band, or similar
techniques.
[0050] With reference to FIG. 6, in accordance with another
exemplary embodiment, a container 600 includes an expulsion portion
602 that can comprise a plastic-type, cylinder or tube-like
structure 602A that suitably encloses a composition and can be
squeezed or otherwise forced for expulsing composition into an
applicator portion 604. For example, a tube-like structure can be
easily gripped with the fingers or hand and squeezed to force any
composition within to be transferred into applicator portion
604.
[0051] While expulsion portion 602 can suitably comprise a cylinder
or tube-like shape 602A, expulsion portion 602 can also comprise a
rectangular shape, a substantially flat-like shape, e.g., that
similar to a hot water bottle, or any other shape that can contain
or store a composition and allow for the expulsion of the
composition by a force. In addition, while such a force can be
suitably applied on an exterior of expulsion portion 602, e.g.,
similar to "squeezing" a tube of toothpaste approximate a
center-section or on one end and rolling or collapsing the tube,
such an expulsion force can also be realized by urging a
plunger-like device against, e.g., much like a syringe, or any
other like manner wherein the amount of force and/or the rate or
expulsion or delivery into applicator portion 604 can be suitably
controlled.
[0052] Container 600 can include an applicator portion 604 that is
suitably molded in a unitary structure with expulsion portion 602.
For example, container 600 can comprise an injection molded
tube-like structure for portions 602 and 604. In accordance with
other embodiments, applicator portion 604 can suitably comprise a
separate component that is suitably screwed, press-fit, clamped or
otherwise permanently, semi-permanently or removably attached to
expulsion portion 602.
[0053] In accordance with an example of an embodiment, applicator
portion 604 comprises a passive structure to allow a composition to
be forced through an applicator tip 612 and onto a surface. For
example, applicator portion 604 can comprise a semi-rigid or
substantially rigid tube-like component 604A configured to allow
composition to flow to applicator tip 612 upon an expulsion force
being applied to expulsion component 602. In other embodiments,
applicator portion 604 can also be configured as a less-rigid or
otherwise expulsive component to allow for any remaining
composition within applicator portion 604 to be suitably squeezed
or otherwise delivered or applied by applicator tip 612 onto a
surface.
[0054] Applicator tip 612 suitably comprises an opening at a
discharge end of applicator 604 to allow for any composition to be
discharged or otherwise delivered from the opening and applied to a
surface. A composition can be discharged from applicator tip 612
and applied to surface, such as by tilting container 600. As such,
the composition can be targeted for delivery onto a region at
selected amounts and/or locations to achieve a desired treatment,
while avoiding other areas of the oral cavity that composition is
not to be applied or needed. In accordance with an example of an
embodiment, applicator tip 612 can suitably comprise a similar
shape or configuration to that of portion 604A, e.g., a tube
structure; however, applicator tip 612 can also comprise a narrower
or wider cross-sectional configuration. For example, tip 612 may
include a disposable break-away portion, as is described in greater
detail herein.
[0055] Referring to FIGS. 7A-7D, a system 700 in accordance with
another embodiment is illustrated. System 700 is similar to system
600, except system 700 includes an angled spout portion 704 and an
access/closure portion 706, can comprise a detachable device that
suitably separates at a region 706A such that an applicator tip 712
is exposed. To gain access, a user can simply grip and detach,
e.g., by pulling, bending, twisting and/or other like separating
action, to remove access portion 706 from applicator portion 704.
Access portion 706 can be completely detached and removed or
discarded, or substantially detached such as by bending backwards
to provide an opening and yet remain connected with at least some
portion adjacent applicator tip 712.
[0056] In accordance with an example of an embodiment, access
portion 706 can suitably comprise a tab component 708 configured to
allow a user to simply grip and detach. Tab component 708 can
comprise various shapes, thicknesses and sizes for facilitating
easier removal of access portion 706 from applicator portion 704.
Tab component 708 further comprises a closed end, i.e., without an
opening or otherwise configured to facilitate a sealed closure of
applicator portion 704. Having tab component 704 can making
gripping of access portion 706 easier, although other examples of
embodiments can be configured without tab component 708, such as
access portion 706 having substantially the same shape,
cross-sectional area and/or configuration of applicator portion
704.
[0057] In FIGS. 7A-7D, access portion 706 comprises a detachable
component that remains detached, e.g., region 706A and applicator
tip 712 are not made for re-attachment. Such embodiments may be
desirable for single or other short term uses. In accordance with
other examples of embodiments, access portion 706 can comprise a
re-attachable configuration in which a detached region can be
suitably screwed, clamped, press-fit or otherwise re-attached to
applicator portion 704, such as to enable re-use over a period of
days. In addition, to prevent misplacement after detaching or
opening, access portion 706 can comprise a strap portion that
surrounds or is otherwise attached to applicator portion 704 or any
other part of container 700 that allows for access portion 704 to
be suitably found and used to reseal or close applicator portion
704 after use.
[0058] Referring now to FIGS. 8A and 8B, in accordance with an
exemplary embodiment a kit 800 includes an application tray 850 and
a plurality of containers. The kit may include any suitable number
or supply of containers. In the illustrated embodiment, kit 800
includes a two-week daily supply of containers 804, each such
container 804 suitably stored or maintained within a plurality of
compartments 852. The size and shape of compartments 852 can be
configured in various arrangements, e.g., square or rectangular,
circular or other like shapes, to suitably contain containers 804
within during transporting or other uses of application tray 850.
In addition, application tray 850, including compartments 852, can
comprise various materials, such as paperboard, plastics,
thin-alloys, fiberglass, or other composites, or any combination of
materials thereof, for providing the storage functions.
[0059] To further secure containers 804 within application tray
850, in accordance with an example of an embodiment, each
compartment 852 can be configured with an opening, e.g., the
spacing between compartment sides 852A, only slightly larger than
an outer circumference or perimeter of containers 804 to facilitate
a snug or tight fit when containers 804 are placed within
compartments 852. In accordance with another example of an
embodiment, each compartment 852 can also comprise a carved-out,
bottom portion having a shape substantially conforming to a bottom
shape of containers 804 to facilitate a snug or otherwise secure
fit within compartments 852. Such carved-out bottom portions can
comprise various paperboard, plastics, e.g., Styrofoam, or other
like composites capable of providing a substantially conforming
shape with containers 804.
[0060] To facilitate tracking of usage of containers 804, an
example of an application tray 850 can be configured for
identifying and displaying a prescribed period for systematic
application of containers to facilitate compliance with a
prescribed treatment plan. For example, in accordance with the
embodiment illustrated in FIG. 8A, application tray 850 can
comprise one or more period indicators 854A and 854B, e.g., a first
week and a second week of a two-week supply, as well as single-dose
container indicators 856, e.g., the days of the week. Thus, for
example, for a two-week supply of single-dose containers 804
prescribed for daily use, a user can simply retrieve a single
container 804 beginning on the first day of the week, i.e., Sunday,
and selectively apply to a targeted area of an oral cavity
interface, and discard that container 804 after use, followed by
retrieval, application and use of remaining containers 804 as the
weeks progress until the two-week supply is exhausted.
[0061] While the application tray 850 illustrated in FIGS. 8A and
8B comprises a two-week supply, shorter or longer periods of
treatment and/or shorter or longer time periods between
applications of containers 804 can also be provided within
application trays 850. For example, application tray 850 can be
configured to store and maintain a one-week supply, a month supply,
three-month supply, or a year-supply, or any other shorter or
longer prescribed periods depending on the prescribed treatment
plan. In addition, the time period between prescribed uses of
containers 804 can be configured for a morning and an
evening/nighttime use, e.g., a.m. and p.m. indicators 856, or over
periods of every one, two or three days or longer. In accordance
with an example of an embodiment, application trays 850 can be
configured for stacking, e.g., with a top cover surrounding
containers 804 and/or with sides 852 extending to a height at least
as long as the vertical length of containers 804. Such application
trays 850 can be configured for discarding after use of all
containers 804 within, or for restocking with new containers 804
ready for selective application of composition.
[0062] In an example of an embodiment, application tray 850
provides an integrated recordation device for further tracking
usage of a plurality of containers 804, for example, to determine
how many containers 804 have been used within a prescribed period
of treatment, e.g., within two-week periods 854A and 854B, and/or
how many containers 804 are remaining to be used within the
prescribed period, e.g., indicators 856 can indicate that three
containers 856 have been used, and that four days of containers 804
are remaining. A recordation device can also comprise a separate
component, for example, an information and/or recordation display
card that can be suitably folded or otherwise inserted within or
coupled to application tray 850 that allows a user to mark-off,
e.g., with a writing instrument or through puncture of use
indicators configured within the display card.
[0063] Regardless of whether integrated within an application tray
or comprising a separate component, a recordation device can also
comprise other related information about a composition and/or a
prescribed treatment plan. For example, information regarding the
expiration or expectancy of effective use of composition 104 can be
suitably configured on application tray 850 or otherwise on a
separate display card, as well as a summary or detailed explanation
of the prescribed treatment plan and/or instructions on how to
selectively apply composition 104 depending on the target area of
an oral cavity interface.
[0064] Referring to FIG. 9, as well as continuing reference to
FIGS. 7A-7D, a method 900 of facilitating and maintaining oral
health care through regular applications of oral compositions can
include providing prescribed dosages of any composition within a
plurality of containers (902), retrieving a single container and
accessing a composition within the container (904), and selectively
applying a composition to a surface and discarding of used
container (906).
[0065] Providing prescribed dosages of a composition within a
plurality of containers can comprise any method now known or
hereinafter devised for filling containers with a substantially
liquid or other like composition. For example, composition 104 can
be suitably filled in one end of container 702 and then sealed to
maintain composition 104 within container 702. In addition,
providing composition 104 within container 702 can include
providing a single and/or daily dose of composition 104, or
multiple doses of composition 104.
[0066] Retrieving a single container 702 and accessing composition
104 within the container 102 may include retrieval from a storage
system and removal of an access or closure device or component from
container 702. For example, in accordance with an example of an
embodiment, retrieval from a storage system can comprise retrieval
from an application tray 850, while accessing composition 104
within container 702 comprises detachably removing of an access
component, e.g., access portion 706, to provide an applicator
tip.
[0067] Selectively applying composition 104 to an oral cavity
interface and discarding of used container 702 can suitably
comprise expulsing or otherwise forcing or delivering composition
104 from a storage portion to an applicator portion of container
702. For example, in accordance with an example of an embodiment,
composition 104 can be "squeezed" from an expulsion portion, such
as expulsion portion 712, into an applicator portion, such as 704,
through an applicator tip, such as 704 and onto a targeted region
of oral cavity interface. In accordance with another example of an
embodiment, applying with an applicator portion 704 can be realized
through an angled portion configured to facilitate targeted
placement of composition 104. After such use, a container 702 can
be suitably discarded and a next prescribed use can be initiated
with a new, filled container 702. As a result, regular and/or
systematic use systems described herein at one or more target
regions can result in improved oral health.
[0068] As noted above, systems in accordance with the invention
include material e.g., material 104 within an assembly--e.g.,
assembly 102. In accordance with various exemplary embodiments of
the invention, material 104 includes an active ingredient, such as
an active oral care ingredient. As explained in greater detail
below, exemplary material 104 is designed to maintain the active
ingredient in contact with a surface for an extended period of time
to allow the active ingredient(s) to stay in contact with possibly
affected areas on the surface.
[0069] In accordance with various aspects of this embodiment, the
active ingredients include one or more of the following:
cetylpyridinium chloride (CPC), dicalcium phosphate dehydrate,
hydrogen peroxide, sanguinaria extract, sodium bicarbonate, sodium
lauryl sulfate, stannous fluoride, zinc salts such as zinc
chloride, zinc acetate, zinc citrate, and zinc gluconate, zinc
oxide, alkyl dimethyl amine oxide, alkyl dimethyl glycine,
eucalyptol, menthol, methyl salicylate, thymol, sodium citrate,
peppermint oil, sage oil, polymethylsiloxane, polxamer, and
stannous pyrophosphate.
[0070] An amount of the active ingredient varies in accordance with
the dosage size and particular ingredient. In accordance with
particular examples, an active ingredient is present in an amount
of about 0.001 wt % to about 1.5 wt %, preferably about 0.025 wt %
to about 1.0 wt %, and more preferably, about 0.05 wt % to about
0.7 wt %. All percentages set forth herein are in weight percent of
the total material, unless otherwise indicated.
[0071] In accordance with particular examples of this exemplary
embodiment of the invention, the active ingredient includes CPC. In
this case, the CPC is present in an amount of about 0.001% to about
1%, preferably about 0.01% to about 0.5%, and more preferably about
0.05% to about 0.25% or about 0.045% to about 0.10%.
[0072] In accordance with other examples, the active ingredient
includes zinc gluconate. In this case, the zinc gluconate is
present in an amount of about 0.001% to about 1.5%, preferably
about 0.01% to about 1.0%, and more preferably about 0.05% to about
0.75%.
[0073] In accordance with further aspects, the material includes a
thickener to obtain the desired viscosity. Suitable thickening
agents include substances which increases the viscosity of the
material, cause the material to gel or coagulate, or the like, such
as food-grade or pharmaceutical grade thickeners, including, for
example, hydroxyethylcellulose, glycerin, carrageenan, guar gum,
methylcellulose, methyethylecellulose, aloe vera, and the like. The
thickener is present in an amount of about 0.01 to about 10%,
preferably about 0.1 to about 7%, and more preferably about 1% to
about 5% or about 0.5% to about 3%.
[0074] The material may also include a humectant such a glycerin,
which may be present in an amount of about 0.01% to about 15%,
preferably about 0.1% to about 10%, and more preferably about 1 to
about 7%. When used, the humectant may facilitate maintaining the
material in a liquid form and may help maintain a desired viscosity
of the material. In addition, glycerin may facilitate maintaining
one or more of the active ingredients in an ionic form and may
facilitate the transport of the active ingredients through the
material.
[0075] The composition may also include a diluent. Exemplary
diluents suitable for use with the present composition include
Sorbitol, Xylitol, Mannitol, water, alcohols, and oils. In
accordance with particular examples of the invention, the
composition includes purified water in an amount of about 80% to
about 99%, preferably about 85% to about 95%, and more preferably
about 88% to about 92%.
[0076] Composition 104 may also include sugar alcohols such as
sorbitol and xylitol, monnital, lactitol, and the like that act as
a sweetener and also as a humectant and/or emulsifier. When used,
sorbitol or other sugar alcohol can be present in an amount of
about 0.001% to about 0.5%, in an amount of about 0.01% to about
0.1%, or even in an amount of about 0.025% to about 0.075%.
Compositions in accordance with the invention may alternatively
includes a greater percentage of sugar alcohol(s).
[0077] Composition 104 may also include a natural or artificial
sweetener such as Magnasweet, cyclamates, sucralose, saccharin
(e.g., sodium or calcium), ace-k, or aspartame which, when included
in composition 104, can be present in an amount of about 0.001% to
about 1.5%, in an amount of about 0.01% to about 1%, or even in an
amount of about 0.25% to about 0.75%.
[0078] Colorants may also be added to the material as desired. In
accordance with various aspects, the material includes colorants,
such that when the material is applied to or proximate the gingiva,
the material has a color indicative of healthy gingiva--i.e., the
material is pink in color. Providing a material having a color
indicative of healthy gingiva provides added incentive to users to
continue using the material, which in turn promotes measurable
improvement in oral health indices. Additionally or alternatively,
colorants, which are indicative of flavor may be added to the
composition. Examples include FD&C Blue #1, D&C Green #5,
FD&C Yellow #5, and FD&C Yellow #6.
[0079] The material also optionally includes flavorants such as
cinnamon bark oil, clove bud oil, mint flavorings, citrus
flavorings, and the like. By way of one particular example, a
material includes cinnamon bark oil present in an about of about
0.001% to about 2%, preferably about 0.01% to about 1%, and more
preferably about 0.1% to about 0.5%; and clove bud oil in an amount
of about 0.001% to about 2%, preferably about 0.002% to about 1%,
and more preferably about 0.003% to about 0.0075%.
[0080] The viscosity of the material is configured to maintain the
material in contact with a surface for an extended period of time,
which has several advantages over traditional materials used to
promote oral health. For example, because the material is viscous
and "sticks" to a surface to which it is applied, relatively small
amounts of the material and consequently the active agent(s) can be
used to effectively prevent or remove plaque and/or tartar buildup
on a surface. This is advantageous, not only from an economic
viewpoint, but it also reduces an amount of the material that may
be ingested. Additionally, the viscosity of the material enables
easy delivery of the material from its container, while also
facilitating maintaining the material in contact particular areas
within an oral cavity, such as the crevices within teeth and
between the teeth and gingiva. In accordance with further
embodiments of the invention, the viscosity is low enough to allow
application of the material to desired locations within the oral
cavity.
[0081] Exemplary materials have a viscosity greater than about
20,000 cp, preferably greater than 30,000 cp, and more preferably
greater than about 35,000 cp. By way of more particular examples,
the viscosity of materials range from about 20,000 to about 250,000
cp, preferably about 25,000 to about 100,000, and more preferably
about 30,000 to about 50,000 cp, and yet more preferably about
35,000 to about 45,000 cp. The viscosity values as set forth herein
are measured at 77 F (25 C) using Spindle #6 at 10 RPM using a
Brookfield, Model DV-II+ Pro, spindle # 6, 10 RPM for 90 seconds at
25 C.
[0082] By way of example, a material in accordance with this
embodiment of the invention includes CPC and zinc gluconate as the
active ingredients and hydroxyethylcellulose as the thickener. In
one case, the CPC is present in an amount of about 0.001% to about
1%, preferably about 0.01% to about 0.5%, and more preferably about
0.05% to about 0.25% or about 0.045% to about 0.1%; the zinc
gluconate is present in an amount of about 0.001% to about 1.5%,
preferably about 0.01% to about 1.0%, and more preferably about
0.05% to about 0.75%; and the hydroxyethylcellulose is present in
an amount of an amount of about 0.01 to about 10%, preferably about
0.1 to about 7%, and more preferably about 1% to about 5%.
[0083] The present invention has been described above with
reference to examples of embodiments. Changes and modifications may
be made to the embodiments without departing from the scope of the
invention. For instance, some embodiments of the present invention
have been described in connection with snap-fit connections.
However, other techniques, such as tread and lug techniques, for
connecting sections of an example of an assembly are also within
the scope of the invention. Further, any element of an embodiment
discussed above may be combined in any manner with any other
element of any other embodiment discussed above. These and other
changes or modifications are intended to be included within the
scope of the present invention.
