Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims benefit under 35 U.S.C. .sctn.119(e)
of U.S. Provisional Patent Application Ser. No. 61/304,216 filed on
Feb. 12, 2010 in the United States Patent and Trademark Office
entitled "Squeezable Beverage Bottle." The entire disclosure of
U.S. Provisional Patent Application Ser. No. 61/304,216 is
incorporated by reference as if fully disclosed herein.
TECHNICAL FIELD
[0002] The present disclosure relates generally to containers and,
in particular, to filtering systems for beverage bottles.
BACKGROUND
[0003] Conventional portable water bottles are typically used to
provide a thirst-quenching liquid to a person. Such bottles often
include a plastic container having a removable lid, cover, cap, or
other structure secured to an opening of the container to close off
the container. Water could be obtained from the container for
drinking but with no guarantee on the integrity or degree of
filtering for such water.
[0004] Conventional filter media materials such as, for example,
carbon filters, easily break apart and require special handling.
Conventional manufacturing methods for filtering systems often
times result in wasted filter media material.
[0005] An object of one embodiment of the present disclosure is to
provide a relatively inexpensive filter system for a beverage
bottle that provides an acceptable degree of filtering water
transported in the bottle and provides a desirable flow rate.
Another object of the present disclosure is to provide an easy to
manufacture and cost-effective bottle mountable filtration
system.
SUMMARY
[0006] Embodiments of the present disclosure could provide a bottle
mountable filtration system that delivers an acceptable level of
filtration of water transported in the bottle.
[0007] In one embodiment, the present disclosure could provide a
bottle filter system. The system could include a filter media
having a first end disposed along the proximate end of a filter
housing and a second end disposed along the distal end of the
filter housing. The filter could also include a support structure
disposed along an interior surface of the proximate end of the
filter housing. The support structure could compress the first end
of the filter media to prevent water housed in the bottle from
bypassing the compressed seal between the support structure and the
filter media.
[0008] In one embodiment, the present disclosure could provide a
bottle filter system. The system could include a filter housing
removably mounted within a bottle having a proximate end and a
distal end. The system could also include a filter media comprising
a first end and a second end. The first end could be disposed along
the proximate end of the filter housing and the second end could be
disposed along the distal end of the filter housing. The system
could also include a support structure disposed along an interior
surface of the proximate end of the filter housing. The support
structure could be further disposed along a bottom surface of a
discharge mechanism of the bottle. The support structure could be
configured to cut into the first end of the filter media when the
filter media is in an engaged position within the filter housing.
The system could also include a secondary support structure
disposed along an interior surface of the distal end of the filter
housing. The secondary support structure could be configured to cut
into the second end of the filter media when the filter media is in
an engaged position within the filter housing.
[0009] In one embodiment, the present disclosure could provide a
bottle filter system. The system could include a filter housing
removably mounted within a bottle having a proximate end and a
distal end. The system could also include a carbon-based filter
media comprising a first end and a second end. The first end could
be disposed along the proximate end of the filter housing and the
second end could be disposed along the distal end of the filter
housing. The system could also include an annular support structure
disposed along an interior surface of the proximate end of the
filter housing and further disposed along a bottom surface of a
discharge mechanism of the bottle. The support structure could be
configured to cut into the first end of the filter media when the
filter media is in an engaged position within the filter housing.
The system could also include a crossbar-like secondary support
structure disposed along an interior surface of the distal end of
the filter housing. The secondary support structure could be
configured to cut into the second end of the filter media when the
filter media is in an engaged position within the filter
housing.

DETAILED DESCRIPTION
[0044] The present disclosure generally provides a relatively
inexpensive filtration system for disposable bottles or,
alternatively, reusable bottles for transporting water or other
liquids to thus provide an environmentally friendly option to
conventional bottled water systems. In one embodiment, the present
disclosure could include a support system to adequately secure the
filter media within a filter housing while ensuring a sufficient
compression fit and seal of filter media within filter system to
eliminate "bypass flow" (i.e., water that might leak past filter
system) and prevent consumption of unfiltered water.
[0045] In one embodiment, the present disclosure could be
particularly suitable for use in a bottle mountable filtration
system such as those disclosed in U.S. Pat. Nos. 6,569,329 and
5,609,759. Although the following description generally describes a
filter system for use with a "squeezable" bottle, it should be
understood that embodiments of the present disclosure could be used
with any suitably sized, shaped, or configured bottle, container,
or container-like receptacle including, for example, rigid bottles
and containers that are not squeezable. FIGS. 1A-2C are somewhat
simplified plan views of a relatively small reusable squeezable
beverage bottle 100 according to one embodiment of the present
disclosure. FIG. 3A is a somewhat simplified exploded perspective
view of bottle 100, while FIG. 3B is a somewhat simplified
perspective view of bottle 100 according to one embodiment of the
present disclosure. It should be understood that bottle 100 shown
in FIGS. 1A-3B are for illustrative purposes only and that any
other bottle or bottle-like system or subsystem could be used in
conjunction with or in lieu of bottle 100 according to one
embodiment of the present disclosure.
[0046] In addition, it should also be understood that while FIGS.
1A-3B illustrate a relatively small bottle 100 (e.g., 375 mL
bottle), FIGS. 4A-6B similarly illustrate a relatively medium-sized
bottle 400 (e.g., 550 mL bottle) having similar characteristics to
bottle 100. Likewise, FIGS. 7A-9B illustrate a relatively
large-sized bottle 700 (e.g., 1000 mL bottle) having similar
characteristics to bottle 100. It should be understood that bottles
400 and 700 shown in FIGS. 4A-6B and 7A-9B, respectively, are for
illustrative purposes only and that any other bottle or bottle-like
system or subsystem, regardless of volume capacity, could be used
in conjunction with or in lieu of bottles 400 and 700 according to
one embodiment of the present disclosure.
[0047] FIG. 10A is a somewhat simplified side plan view of a filter
system 118 for use with bottles 100, 400, and 700 according to one
embodiment of the present disclosure, while FIG. 10B is a somewhat
simplified view along section B-B of filter system 118. FIG. 10C is
a somewhat simplified top plan view of the filter system shown in
FIG. 10A according to one embodiment of the present disclosure,
while FIG. 10D is a somewhat simplified view along section A-A of
the filter system shown in FIG. 10C. Additionally, FIG. 10E is a
somewhat simplified perspective view of the filter system shown in
FIG. 10A according to one embodiment of the present disclosure. It
should be understood that filter system 118 shown in FIGS. 10A-E is
for illustrative purposes only and that any other filter or
filter-like system or subsystem could be used in conjunction with
or in lieu of filter system 118 according to one embodiment of the
present disclosure.
[0048] FIG. 11A is a somewhat simplified plan view of a filter
system 118 and discharge mechanism 116 assembly according to one
embodiment of the present disclosure, while FIG. 11B is a somewhat
simplified view along section C-C of the filter system and
discharge mechanism assembly shown in FIG. 11A. It should be
understood that the filter system 118 and discharge mechanism 116
assembly shown in FIGS. 11A and 11B are for illustrative purposes
only and that any other filter or filter-like system or subsystem,
or discharge mechanism system or subsystem could be used in
conjunction with or in lieu of filter system 118 or discharge
mechanism 116 according to one embodiment of the present
disclosure.
[0049] Although bottles 100, 400, and 700 are generally illustrated
having a somewhat contoured hourglass-like shape and a relatively
smooth exterior surface, it should be understood that bottles 100,
400, and 700 could include any suitable size, shape, configuration,
structure, accessory, or other various features according to one
embodiment of the present disclosure.
[0050] In one embodiment, bottles 100, 400, and 700 could include
elongated body 102, concave portion (or "waist") 104, cap 106, neck
108, opening 110, screw top 111, bottom 112, gate vestige 114,
discharge mechanism 116, filter system 118, filter media 120, and
discharge tube 122 as generally shown in FIGS. 1A-9B.
[0051] Bottles 100, 400, and 700 and their individual components
could be made of any suitable material including, for example,
polyethylene terephthalate (PET or PETE), high density polyethylene
(HDPE), low density polyethylene (LDPE), thermoplastic polymer,
polypropylene, oriented polypropylene, polyurethane, polyvinyl
chloride (PVC), polytetrafluoroethylene (PTFE), polyester,
high-gloss polyester, metal, synthetic rubber, natural rubber,
silicone, nylon, polymer, antibacterial or antimicrobial materials,
insulating, thermal, other suitable sustainable or biodegradable
materials, or any combination thereof according to one embodiment
of the present disclosure.
[0052] In one embodiment, bottle 100 could be made of about 28.0
g.+-.2.0 g PETE, bottle 400 could be made of about 37.0 g.+-.2.0 g
PETE, and bottle 700 could be made of about 47.0 g.+-.2.0 g PETE.
In still other embodiments, bottle 100 could be made of about 18.0
g.+-.2.0 g oriented polypropylene, bottle 400 could be made of
about 24.0 g.+-.2.0 g oriented polypropylene, and bottle 700 could
be made of about 31.0 g.+-.2.0 g oriented polypropylene.
[0053] In one embodiment, bottles 100, 400, and 700 could be
manufactured according to certain specifications (e.g., wall
thickness or weight of material) to achieve desired performance
criteria. As an example, the relative dimensions of bottles 100,
400, and 700 could be customized to achieve certain desirable
physical or performance characteristics such as, for example,
bottle stiffness, recovery strength, flow rate, discharge rate,
material distribution, side load rigidity, waist diameter, waist to
base diameter ratio, waist to outer diameter ratio, angle of
transition of the shoulder, filter specifications, bottle volume
limits, material integrity, material sustainability, antibacterial
or antimicrobial specifications, other suitable "bounce back" or
environmental related thresholds, or any combination thereof.
[0054] In one embodiment, bottle 100 could generally include a
height of about 6.00 inches, an outer diameter of about 2.81
inches, and a waist to outer diameter ratio of about 80.0%.+-.5.0%.
Similarly, in one embodiment, bottle 400 could generally include a
height of about 7.34 inches, an outer diameter of about 3.01
inches, and a waist to outer diameter ratio of about 80.0%.+-.5.0%.
Likewise, in one embodiment, bottle 700 could generally include a
height of about 9.26 inches, an outer diameter of about 3.48
inches, and a waist to outer diameter ratio of about
80.0%.+-.5.0%.
[0055] In one embodiment, the wall of elongated body 102 could
include a thickness in the range of about 0.018-0.028 inches to
achieve material usage efficiency and a reduction in environmental
effects. With this range of wall thickness, bottles 100, 400, and
700 generally exhibit favorable elasticity properties after being
squeezed. Bottles 100, 400, and 700 thus retain their shape and
structural integrity even after repeated use unlike conventional
disposable water bottles, which typically have a wall thickness of
about 0.008-0.012 inches. In a more specific embodiment, the wall
thickness of bottles 100, 400, and 700 could include a thickness of
about 0.023 inches. It should be understood that bottles 100, 400,
and 700 could be manufactured with thicker (or thinner) walls to
provide sufficient recovery force for the "bounce back" or
breathing cycle allowing bottles 100, 400, and 700 to return to
their original shape according to one embodiment of the present
disclosure.
[0056] In one embodiment, elongated body 102 and other parts of
bottles 100, 400, and 700 could include a blow-molded plastic
structure manufactured using, for example, a generally two-step
process according to one embodiment of the present disclosure. The
two-step process could include making an appropriate "pre-form"
structure using an injection molding technique and then creating
the final bottle shape (including, for example, concave portion
104, neck 108, opening 110, bottom 112, and gate vestige 114) using
a "reheat and stretch" blow molding technique. In one embodiment,
the plastic or other material used to make elongated body 102 is
heated in an extruder, which extrudes a tubular stream of plastic
forming the general structure for bottles 100, 400, and 700.
[0057] In one example, a container mold, corresponding to the shape
of bottles 100, 400, or 700, closes around the outer part of the
tubular stream of plastic. Compressed air could be inserted near
the top of the mold to blow pressure into the mold, creating
pressure which pushes the tubular plastic stream outward along the
contour of the inside of the mold. In this manner, the plastic
stream is shaped and cooled to produce the desired plastic
container for bottles 100, 400, or 700. In addition, elongated body
102 could include a smooth exterior surface to allow adhesive
labels to adhere sufficiently or printing/etching on the exterior
surface of bottles 100, 400, and 700.
[0058] In one embodiment, concave portion 104 could aid in handling
bottles 100, 400, and 700. For example, concave portion 104 could
be relatively easily squeezed by hand to facilitate the flow of
liquid out of bottles 100, 400, and 700. Concave portion 104 could
exhibit a favorable rate of deformation and return to its original
shape (i.e., "breathability") after one uses bottles 100, 400, and
700. As an example, if one were to squeeze bottle 100 (e.g.,
generally in the area including concave portion 104) to facilitate
the flow of liquid to an opening of bottle 100 via discharge tube
122, bottle 100 could exhibit sufficient rigidity and elasticity to
return air into bottle 100. Accordingly, bottle 100 could return to
its original shape (or "bounce back") at a suitable rate without
experiencing permanent deformation or denting to any surface of
bottle 100 or bottle 100 in general.
[0059] Similarly, if bottle 100 were fitted with bottle mountable
filter system 118 as shown in FIG. 2A, for example, and one were to
squeeze bottle 100 to facilitate the flow of liquid from bottle 100
through filter 118 and discharge tube 122, bottle 100 could exhibit
sufficient rigidity and elasticity to return air into bottle 100
and thus restore bottle 100 to its original shape (or "bounce
back"). This "bounce back" behavior could occur at a suitable rate
without any permanent deformation or denting to any surface of
bottle 100 or bottle 100 in general. In addition, bottle 100 could
be squeezed using a reasonable threshold (i.e., not excessively
hard) to achieve sufficient flow rates of the liquid discharging
from bottle 100. In one embodiment, liquid could be discharged by
proactively inhaling air from and sucking on discharge mechanism
116 and facilitating a sufficient flow of water out of bottle 100.
In another embodiment, liquid could be discharged from bottle 100
by simultaneously squeezing bottle 100 using a reasonable threshold
and inhaling air from and sucking on discharge mechanism 116.
[0060] The ratio between the smallest outside diameter of concave
portion 104 to the largest outside diameter of body 102 can be
controlled to yield favorable structural characteristics according
to one embodiment of the present disclosure. If, for example,
bottle 100 included a ratio significantly smaller than the
preferred ratio, it may be difficult to achieve proper distribution
of material during the blow molding process and bottle 100 (and, in
particular, its sidewalls) may be subject to kinking and permanent
distortion when squeezed. If, for example, bottle 100 included a
ratio significantly larger than the preferred ratio, the desired
hourglass shape of bottle 100 may be difficult to achieve.
[0061] In one embodiment, the ratio between the major outer
diameters of bottles 100, 400, and 700 and their respective concave
portions 104 (i.e., the waist) could be about 80.0%.+-.5.0%. In
other words, in one example, if the outside diameter of bottle 100
is about 2.81 inches, then the smallest outside diameter of concave
portion 104 could be about 2.22 inches.+-.0.140 inches. Similarly,
if the outside diameter of bottle 400 is about 3.01 inches, then
the smallest outside diameter of concave portion 104 could be about
2.41 inches.+-.0.150 inches. Likewise, if the outside diameter of
bottle 700 is about 3.48 inches, then the smallest outside diameter
of concave portion 104 could be about 2.79 inches.+-.0.174
inches.
[0062] Cap 106, neck 108, opening 110, bottom 112, gate vestige
114, and discharge mechanism 116 generally shown in FIGS. 1A-9B
could include any suitable size, shape, configuration, structure,
accessory, or other various features according to one embodiment of
the present disclosure. In one example, cap 106, neck 108, opening
110, bottom 112, gate vestige 114, and/or discharge mechanism 116
could be coated with or treated with antibacterial or antimicrobial
materials to reduce contamination of the water stored in or
dispersed by bottles 100, 400, and 700.
[0063] In one embodiment, cap 106 could be coupled with neck 108,
opening 110, and/or discharge mechanism 116 to provide a cover for
bottles 100, 400, and 700. Neck 108 is generally disposed between
one end of body 102 and opening 110. In one embodiment, neck 108
could generally include an inner diameter of about 1.040 inches and
any reasonable range of tolerances. The angle of transition of the
shoulder (i.e., the angle between: (a) a tangent to body 102 at an
intersection between body 102 and neck 108; and (b) a line
perpendicular to a vertical axis of body 102) could be controlled
to aid in distribution of material during the blow molding process
to make bottles 100, 400, and 700. Although the transition angle
could be in the range of about 20.0-45.0 degrees, in one
embodiment, the transition angle could be about 30.0 degrees and
could include any reasonable range of tolerances.
[0064] In one embodiment, opening 110 could generally include an
inner diameter of about 1.040 inches and include any reasonable
range of tolerances. In one embodiment, gate vestige 114 could be
disposed along bottom 112 and could generally provide bottles 100,
400, and 700 additional burst strength or resistance. Discharge
mechanism 116 could be coupled to neck 108 and opening 110 and
provide an outlet for dispersing filtered water to the user
according to one embodiment of the present disclosure.
[0065] Screw top 111 could include any suitable structure to retain
or otherwise couple discharge mechanism 116 to neck 108 according
to one embodiment of the present disclosure. In one embodiment,
screw top 111 could include a clockwise oriented thread or a
counter-clockwise oriented thread. It should be understood,
however, that any suitable mechanism of coupling discharge
mechanism 116 to couple screw top 111 to neck 108 could be used
according to one embodiment of the present disclosure including,
for example, a compression coupling, magnetic coupling, a coupling
sleeve, any other suitable coupling mechanism, or any combination
thereof.
[0066] Filter system 118 is generally coupled with and fluidly
connects bottles 100, 400, and 700 containing liquids to discharge
mechanism 116 according to one embodiment of the present
disclosure. Filter system 118 could be reused, retrofitted, or
replaced as needed or desired. Filter system 118 could include a
filter housing having a height of about 3.407 inches and an outer
diameter of about 0.911 inches, and a slotted filtering area with a
height of about 3.092 inches according to one embodiment of the
present disclosure.
[0067] In one embodiment, the surface area of filter system 118
available to the contents of bottles 100, 400, and 700 could affect
the filtering capability of bottles 100, 400, and 700. Filter
system 118 could include an outside surface area (including the
outside diameter and the bottom of filter system 118) of about 7.44
square inches and an open area (having slots in the housing of
filter system) of about 2.50 square inches according to one
embodiment of the present disclosure.
[0068] Filter system 118 could include any suitable filter media
120 including, for example, a carbon, active carbon, charcoal,
reverse osmosis, distiller, backwash, other suitable filter, or any
combination thereof. In one embodiment, filter media 120 could
include one or more carbon cartridges having, for example, a height
of about 3.10 inches and a diameter of about 0.730 inches. Both the
height and diameter of filter media 120 could include any
reasonable range of tolerance. It has been observed, however, that
the range of tolerances for filter media 120 could be as much as
1/8 of an inch or more. In one embodiment, however, the diameter of
filter media 120 could include a tolerance of about .+-.0.010
inches while the length of filter media 120 could include a
tolerance of about .+-.0.015 inches.
[0069] In one embodiment, filter media 120 could have a water flow
rate within a certain range to achieve desired performance
criteria. Once water is discharged through filter system 118 and
discharge mechanism 116, the air returning into bottle must pass
through this same filter media 120. Accordingly, the return airflow
could essentially provide cleansing or backwashing function that
prolongs the usable life of filter system 118 according to one
embodiment of the present disclosure. Similarly, any residual
liquid remaining in discharge mechanism 116 may return into bottle
through filter media 120 and provide a cleansing or backwashing
function.
[0070] According to one embodiment of the present disclosure,
filter media 120 could be secured or otherwise disposed within the
filter housing of filter system 118 by supporting structures
associated with filter system 118 and discharge mechanism 116. For
example, a proximate end of filter media 120 could be supported by
one or more support structures 1002 disposed along a bottom surface
of discharge mechanism 116, while a distal end of filter media 120
could be supported by one or more secondary support structures 1004
disposed along an interior surface of the housing of filter system
118 as generally shown in FIGS. 10A-10E, 11A, and 11B.
[0071] In one embodiment, support structure 1002 could be a
generally annular structure disposed along a bottom surface of
discharge mechanism 116 and include a length sufficient enough to
cut into a proximate end of filter media 120 as generally shown in
FIG. 11B. Secondary support structure 1004, on the other hand,
could be a generally cross-bar like structure disposed along an
interior bottom surface of the housing of filter system 118 as
generally shown in FIGS. 10C, 10D, and 10E. Secondary support
structure 1004 could be configured to cut into a distal end of
filter media 120 without crushing filter media 120 when filter
media 120 is in a fully engaged position within the housing of
filter system 118. Since both support structure 1002 and secondary
support structure 1004 cut into opposite ends of filter media, the
housing of filter system 118 can accommodate filter media 120 of
varying lengths while still applying compression force along the
length of filter media 120.
[0072] It should be understood that support structure 1002 and
secondary support structure 1004 could accommodate tolerance
differences in size, shape, or configuration of filter media 120.
Accordingly, support structure 1002 and secondary support structure
1004 could ensure a sufficient compression fit and seal of filter
media 120 within filter system 118 and thus eliminate, for example,
any "bypass flow" water that might leak past filter system 118) and
prevent consumption of unfiltered water. For example, secondary
support structure 1004 may apply axial pressure to filter media 120
sufficient to force filter media 120 against support structure
1002, thus creating a seal between filter media 120 and support
structure 1002.
[0073] In one embodiment, the distal end of filter media 120 could
be compressed against a bottom surface of filter housing 118 by
secondary support structure 1004. The proximate end of filter media
120 could be compressed against screw top 111 and in particular
support structure 1002 according to one embodiment of the present
disclosure. In one embodiment, when filter media 120 is in a fully
engaged position, secondary support structure 1004 could aid in
accommodating any deviations in tolerance in the overall length or
shape of filter media 120 and ensure an adequate seal between
filter media 120 and filter system 118. Even if some of filter
media 120 are too short and do not fully engage with secondary
support structure 1004, the proximate end of filter media 120 still
provides an adequate seal with support structure 1002 according one
embodiment of the present disclosure.
[0074] It should be understood that support structure 1002 and
secondary support structure 1004 could include any suitably sized,
shaped, or configured support structure to secure or otherwise aid
in disposing filter media 120 within the housing of filter system
118. For example, support structure 1002 and secondary support
structure 1004 could include an annular structure, tapered
structure, ridged structure, ribbed structure, cross-barred
structure, protrusion, compression structure, cut-in structure,
other suitable structure, or any combination thereof.
[0075] Discharge tube 122 could fluidly connect filter system 118
to discharge mechanism 116 and insure that any water discharged
from bottles 100, 400, and 700 passes through filter system 118
according to one embodiment of the present disclosure. In one
embodiment, discharge tube 122 could thus further eliminate any
"bypass flow" (i.e., water that might leak past filter system 118)
and prevent consumption of unfiltered water.
[0076] Accordingly, by matching the properties of the blow molded
bottles 100, 400, and 700 to the properties of the filter system
118, bottles 100, 400, and 700 could generally provide a fully
functioning filtered water bottle "system" with the necessary
degree of filtration and an improved user experience according to
one embodiment of the present disclosure.
[0077] FIG. 12 is a somewhat simplified flow diagram illustrating
method 1200 of producing filter system 118 shown in FIG. 11A
according to one embodiment of the present disclosure. It should be
understood that method 1200 shown in FIG. 12 is for illustrative
purposes only and that any other suitable method or sub-method
could be used in conjunction with or in lieu of method 1200
according to one embodiment of the present disclosure. It should
also be understood that the steps described in conjunction with
method 1200 could be performed in any suitable order.
[0078] Method 1200 could include installing a filter media such as,
for example, filter media 120 described above, to use in filter
system 118 according to one embodiment of the present disclosure.
In step 1202, method 1200 could include selecting an appropriate
bottle to store, hold, or otherwise retain unfiltered water or
other liquid according to one embodiment of the present disclosure.
It should be understood that the selected bottle could include, for
example, bottles 100, 400, and 700, or could include any suitable
size, shape, configuration, structure, accessory, or other various
features according to one embodiment of the present disclosure. In
step 1204, method 1200 could include selecting the appropriate size
and dimensions for a bottle mountable filter system such as, for
example, filter system 118 and filter media 120 according to one
embodiment of the present disclosure.
[0079] In step 1206, method 1200 could include disposing or
otherwise securing filter media 120 to a discharge mechanism such
as, for example, discharge mechanism 116 according to one
embodiment of the present disclosure. In step 1208, method 1200
could include disposing and aligning discharge mechanism 116 and
filter media 120 with the filter housing according to one
embodiment of the present disclosure. In some cases, filter media
120 will be crushed against support structures located internally
within the housing. For example, filter media 120 could ensure a
sufficient compression fit between support structure 1002 and
secondary support structure 1004 and thus prevent consumption of
unfiltered water. In one embodiment, a proximate end of filter
media 120 could be supported by one or more support structures 1002
disposed along a bottom surface of discharge mechanism 116, while a
distal end of filter media 120 could be supported by one or more
secondary support structures 1004 disposed along an interior
surface of the housing of filter system 118 as generally shown in
FIGS. 10A-10E, 11A, and 11B.
[0080] The present disclosure generally provides a relatively
inexpensive filtration system for disposable bottles or,
alternatively, reusable bottles for transporting water or other
liquids to thus provide an environmentally friendly option to
conventional bottled water systems. In one embodiment, the present
disclosure could include a support system to adequately secure the
filter media within a filter housing while ensuring a sufficient
compression fit and seal of filter media within filter system to
eliminate water leaking past filter system and prevent consumption
of unfiltered water.
