Water cooler description
FIELD OF THE INVENTION
The present invention relates generally to a water cooler bottle
and a water cooler system for dispensing cooled water.
DESCRIPTION OF THE PRIOR ART
Water coolers have been common fixtures at offices and homes for
quite some time. These devices typically dispense bottled water
which is free from the impurities associated with regular tap water.
These water coolers are typically comprised of a refrigerated water
dispensing unit and a large bottle of water (typically containing
about 5 gallons of water).
The water dispensing unit typically has a means for receiving the
water bottle on its top side. Typically the large bottle of water
has a spout which must be positioned on the top side of the water
dispensing unit so that the water will flow into a receiving pipe
which will carry the water to a spigot typically located on the
front of the water dispensing unit.
The problem with the current water coolers is the need to refill
the large bottles of water. These bottles, when filled with water,
will typically weigh approximately 40 pounds. The process for replacing
an empty bottle of water typically entails removing the cover which
seals the spout, lifting the water bottle, and inverting the water
bottle so that the spout is positioned right on top of the receiving
pipe. This process is quite cumbersome and requires significant
strength and dexterity. Changing water bottles can lead to excessive
water spillage and to injury if the person changing the water bottle
lacks the strength and dexterity to perform the task.
There is prior art which has attempted to solve this problem by
changing the design of the water bottle, but the prior art typically
has added significant cost to the manufacture of the water bottle
or has not fully addressed the problem of refilling the bottle.
One such attempt to solve the problem of refilling the water bottle
is disclosed in U.S. Pat. No. 5105858. This patent reveals a parallelepipedal
shaped bottle with an elongated spout on one end and a smaller spout
on the other end. The drawback in this design is that it does not
conform to the shape of most water cooler bottles and subsequently
will not fit in most water coolers. Secondly, the process of interconnecting
the spouts located on the top of one bottle and located on the bottom
portion of a second identical bottle is cumbersome and may result
in excessive spillage. Furthermore, this invention does not easily
adapt to the use of different bottles to refill the main bottle
located on the water cooler.
Accordingly, there is a need for a water cooler bottle and a water
cooler system which is easily refillable and still economical to
use.
Accordingly there is also a need for a water cooler bottle which
may be refilled using a variety of different water bottles.
The present invention is an easily refillable water cooler bottle
and a water cooler system for dispensing cooled water.
As will be described in greater detail hereinafter, the present
invention solves the aforementioned and employs a number of novel
features that render it highly advantageous over the prior art.
SUMMARY OF THE INVENTION
Accordingly it is an object of this invention to provide a water
cooler bottle and a water cooler system which is easily refillable
and still economical to use.
Accordingly it is also an object of this invention to provide a
water cooler bottle which may be easily refilled using a variety
of different water bottles.
To achieve these objectives, and in accordance with the purposes
of the present invention the following open top water cooler bottle
and system are presented.
The water cooler bottle is preferably made of a lightweight transparent
plastic, but glass may also be used. The water cooler bottle has
a cylindrical body in order to enable it to be used with most water
cooler units, and is enclosed on one end by a top portion and on
the other end by a bottom portion.
The top portion has a spout portion extending outwardly therefrom.
The spout portion has an opening which is preferably positioned
concentrically to the cylindrical body. The top portion is typically
received by a water dispensing unit. The spout portion is positioned
in alignment with a receiving pipe in the water dispensing unit.
The bottom portion with exception to a circular recessed portion
is preferably horizontal in order to allow the bottle to be stored
in an upright position while resting on the bottom portion. The
circular recessed portion has a wall section and a floor section.
The floor section has an aperture therethrough which is positioned
concentrically to the cylindrical body. The aperture allows the
water cooler bottle to be refilled by simply pouring water into
the water cooler bottle through the aperture. A circular cap is
removably disposed within the circular recessed portion in order
to seal the aperture. The circular cap has a top surface and a side
wall peripherally extending around the cap. The top surface has
a gripping means mounted thereon.
A water cooler bottle is loaded onto a water dispensing unit by
first removing a seal covering the spout portion of the top portion
and then lifting the water cooler bottle by its cylindrical body.
Once the bottle is lifted and by the water dispensing unit, the
water cooler bottle is inverted by grabbing the gripping means on
the cap and manipulating the gripping means to invert the water
cooler bottle onto the water dispensing unit.
Once the water cooler bottle is empty, the water cooler bottle
can be refilled by removing the cap thereby exposing the aperture
in the bottom portion. Most water bottles can be used to refill
the water cooler bottle by simply positioning the spout of the water
bottle in the aperture and allowing the water bottle to rest on
the bottom portion partially disposed within the circular recessed
portion. Gravity, the aperture, and the wall section will combine
to hold most water bottles stable on the bottom portion of the water
cooler bottle. Smaller and lighter one or two gallon bottles can
also be used to fill up the water cooler bottle.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1 the present invention is an easily refillable
water cooler bottle 10 and a water cooler system 11 for dispensing
cooled water. The water cooler bottle 10 is preferably made of a
lightweight transparent plastic, but glass may also be used. The
water cooler bottle has a cylindrical body 12 in order to enable
it to be used with most water dispensing units, and is enclosed
on one end by a top portion 13 and on the other end by a bottom
portion 14. In the preferred embodiment, the water cooler has a
capacity of 5 gallons. Referring to FIG. 5 in an alternative version
of the water cooler, the water cooler has a plurality of bottle
handles 15 which extend from the cylindrical body 12. The bottle
handles 15 provide a grip which enables the water cooler bottle
10 to be easier to handle and maneuver.
Referring to FIGS. 1 and 5 the top portion 13 has a spout portion
17 extending outwardly therefrom. The spout portion 17 has an opening
16 which is preferably positioned concentrically to the cylindrical
body. The top portion 13 is typically received by a water dispensing
unit, with the spout portion 17 in alignment with a receiving pipe
that directs the water to a spigot on the water dispensing unit.
Referring to FIGS. 1 2 and 5 the bottom portion 14 with exception
to a circular recessed portion 18 is preferably horizontal in order
to allow the water cooler bottle 10 to be stored in an upright position.
The circular recessed portion 18 has a wall section 19 and a floor
section 20. In the preferred embodiment, the wall section has a
first set of concentric threads 21 extending therefrom. The floor
section has an aperture 22 therethrough which is positioned concentric
to the cylindrical body, a rubber gasket 23 surrounds the aperture
22. The aperture 22 allows the water cooler bottle to be refilled
by simply pouring water into the water cooler bottle 10 through
the aperture 22.
The aperture is large enough to enable a person to reach inside
the water cooler bottle, while still being sufficiently small to
enable most water containers having a volume of 1 gallon or more
to lie within the aperture without falling through. The diameter
of the aperture is preferably 5 to 6 inches. The diameter of the
aperture allows someone to reach inside the water cooler bottle
and clean the interior of the water cooler bottle so that the water
cooler bottle can be cleaned and reused.
Referring to FIGS. 2 3 and 4 in the preferred embodiment, a
circular cap 24 is removably disposed within the circular recessed
portion 18 in order to seal the aperture 22. The circular cap 22
has a top surface 25 and a side wall 26 peripherally extending around
the circular cap 24. The top surface 25 has a gripping means mounted
thereon. A second set of threads 27 extend outwardly from side wall
26 of the circular cap. The second set of threads 27 are complementary
to the first set of threads 21 on the wall section 19 of the circular
recessed portion 24 allowing the circular cap 24 to screw onto the
recessed portion 18 and form a water tight seal.
In the preferred embodiment, the top surface 25 of the circular
cap 24 is recessed with the side wall 26 extending above the top
surface 25. The gripping means on the cap is a cap handle 30 hingedly
mounted onto the top surface 25 of the circular cap 24. The cap
handle 30 can be raised to a vertical position relatively perpendicular
to the circular cap 24 or to be lowered to a horizontal position
relatively parallel to the circular cap 24. In the horizontal position,
the handle is recessed within circular cap and does not interfere
with the water cooler bottle's ability to sit upright on a flat
surface.
Referring to FIGS. 1 and 5 a water cooler bottle 10 is loaded
onto a water dispensing unit 35 by first removing a seal covering
the spout portion 17 of the top portion 13 and then lifting the
water cooler bottle 10 by its cylindrical body 12. In the alternative
version the water cooler bottle 10 can be lifted by grabbing a bottle
handle 15. Once the water cooler bottle 10 is lifted and by the
water dispensing unit 35 the water cooler bottle 10 is inverted
by grabbing the cap handle 30 and manipulating the cap handle 30
to invert the water cooler bottle 10 onto the water dispensing unit
35. The water dispensing unit receives the water cooler bottle and
has a means for receiving fluid from the spout portion of the water
cooler bottle. The water dispensing unit chills the fluid and then
dispenses the fluid through a spigot.
Referring to FIGS. 5 once the water cooler bottle 10 is empty,
the water cooler bottle 10 can be refilled by removing the cap thereby
exposing the aperture 22 in the bottom portion 14. In the preferred
embodiment, a refilling bottle 36 with a volume of preferably 3
gallons and with a third set of threads 37 on its neck is positioned
over the circular recessed portion 18 of the bottom portion 14.
The third set of threads 37 is complimentary to the first set of
threads 21 on the wall section 19 of the bottom portion 14. The
neck of the refilling bottle 36 is positioned over the aperture
22 and is screwed onto the circular recessed portion 18.
Referring to FIG. 6 alternatively, most water bottles can be used
to refill the water cooler bottle by simply positioning the neck
of the water bottle in the aperture 22 and allowing the water bottle
to rest on the bottom portion 14 partially disposed within the circular
recessed portion 18. Gravity, the aperture 22 the floor section
20 and the wall section 19 will combine to hold most water bottles
securely onto the bottom portion 14 of the water cooler bottle 10.
Smaller and lighter one or two gallon bottles can also be used to
fill up the water cooler bottle.
The foregoing descriptions of the preferred embodiments of the
invention have been presented for purposes of illustration and description,
and are not intended to be exhaustive or to limit the invention
to the precise forms disclosed. The descriptions were selected to
best explain the principles of the invention and their practical
application to enable others skilled in the art to best utilize
