Description
BACKGROUND OF THE INVENTION
The present invention relates generally to refrigerated water or
beverage coolers and dispensers. More particularly, this invention
is concerned with a cabinet-type, electrically refrigerated
cooler-dispenser which is adapted to house and cool one or more
cubicle type, rigid or semi-rigid beverage containers while
providing ready exterior access to the usual discharge valve or
faucet of such containers.
So-called bottle-type water coolers have met with widespread
acceptance in homes, offices, factories and other populated areas.
These bottle-type water coolers usually comprise an upright,
floor-supported cabinet or base in which is contained a
conventional, electrically actuated refrigeration system having a
cooling reservoir to receive the mouth of an inverted, five gallon
water bottle, and a system of outlet pipes and valves to provide
for the gravitational discharge of chilled drinking water from the
cooler.
However, these inverted water bottle-type coolers were and are
subject to numerous objections stemming principally from the
difficulty of handling and the expense of the heavy, large capacity
water bottles. Another objection to the bottle-type water cooler
stems from the fact that the drinking water must be transferred
from the sterile bottle through the air-vented, normally
unsterilized reservoir, pipe and faucet valve system of the cooler,
and the otherwise pure drinking water sometimes becomes
contaminated with impurities during its storage in and travel
through the cooler, thus creating a health problem.
Also, while it has been heretofore proposed to use refrigerated,
cabinet type coolers for the storage and dispensing of milk
packaged in flexible plastic bag-type containers, particularly in
comparatively large restaurant operations, such bag-type coolers
are relatively difficult to load and operate without serious
wastage or contamination of the milk.
SUMMARY AND OBJECTS OF THE INVENTION
This invention provides an improved, electrically refrigerated
cooler-dispenser for disposable-type, faucetequipped plastic
beverage containers and which makes provision for the direct
dispensation of the beverage from the container without passage
thereof through the cooler itself. Toward this end, the
cooler-dispenser comprises a table or pedestal-supported, cabinet
structure, which houses a conventional electrically-operated
refrigeration system and which provides therein a thermally
insulated, cooling compartment adapted to receive and chill one or
more rigid, or semi-rigid cubicle-shaped, plastic beverage
containers of the type having a manually operable discharge valve
or faucet extending outwardly from a lower forward corner hereof,
and wherein the cooling compartment is defined in part by a
downwardly and forwardly sloping bottom wall to support the
beverage container(s) in a forwardly tilted position and thereby
facilitate the discharge of the contents of the container(s), and a
removable door or closure panel which is recessed or notched to
permit the faucet(s) of the beverage container(s) to project
outwardly from the cooling compartment for easy access and
manipulation.
A primary object of this invention is to provide a cooler for
faucet-equipped, disposable plastic-type beverage containers which
is efficient in its cooling function, which provides convenient
access to its cooling compartment for the loading and unloading of
beverage containers therein, and which provides for the exterior
manipulation and discharge of beverage from the container faucet
without transfer of the beverage to any part of the cooler
itself.
Another object is to provide a convenient and compact
electrically-operated cooler for drinking water or other beverage
which is packaged in a sterile condition in a rigid or semi-rigid
disposable plastic container of generally cubicle shape, and which
provides for the dispensing of the beverage directly from the
faucet of the container without removal of the container from the
cooler.
These and other objects and advantages of the invention will be
more readily apparent from the following description and the
accompanying drawings.

DESCRIPTION OF PREFERRED EMBODIMENT
Referring now to the drawings, it will be seen that the present
cooler comprises a vertically elongated, rectangular cabinet or
outer housing 10 which is preferably supported for operation upon a
table top or counter, not shown. The cabinet 10 is divided
internally by a transverse, horizontal partition wall 11 into a
lower, machinery-containing compartment 12 and an upper
refrigerating compartment 13. The lower compartment 12 preferably
houses the usual components of an electrically-operated,
refrigeration system, including an electric motor, compressor,
condenser, valves and conduits, none of which are shown in the
drawings since they are well and familiarly known to those skilled
in the refrigeration art. The evaporator or cooling coils 14 of the
refrigeration system are, however, shown in FIG. 1 as occupying the
upper, refrigerating compartment 13 and disposed in intimate,
heat-exchange contact with the bottom and rear walls 15 and 16 of
an inner, plastic liner or shell 17 carried within the upper
compartment 13. The inner plastic liner or shell 17 is, for the
most part, carried in inwardly spaced relation to the adjacent
outer walls of the cabinet 10, and the spaces between the outer
walls of the cabinet 10 and the inner liner or shell 11 is
preferably filled with foamed plastic or other suitable thermal
insulating material, not shown, so that the cooling coils 14 and
inner shell 11 are well insulated from the outer walls and lower
compartment 12 of the cabinet 10.
As seen particularly in FIG. 1, the inner liner or shell 17 also
includes a top wall 18 which terminates in a forwardly disposed,
upturned, coextensive lip or flange 19 which is rigidly secured to
the outer top wall 20 of the cabinet 10 along the upper forward
corner of the cabinet. The bottom wall 15 of the inner shell 17 is
inclined slightly downwardly toward the front of the cabinet and
merges with an integral, oppositely inclined portion 15a to define
on the forward portion of the bottom wall of the shell 17a
transversely extending drain condensate trough 21. The inner shell
17 is completed by a pair of opposed, upstanding side walls 22. As
will be observed, the inner shell 17 of the cabinet is preferably
molded from plastic or synthetic resin material and defines within
the upper compartment 13 a forwardly opening, cubicle cooling
chamber 23 which is preferably of a size to receive two
faucet-equipped, cubical beverage containers 24 in closely spaced,
side-by-side relation.
A double wall door or closure panel 25 is removably carried in
snug-fitting, closing relation to the forward opening of the
cooling chamber 23 by means of a quick-release, flexible plastic
latch 26. The lower edge 27 of the closure panel 25 is formed with
a pair of relatively spaced arcuate notches or recesses 28 which
are arranged to snugly fit around the stationary sleeve or outer
barrel portion 29 of the manually operable faucets 30 of the
beverage containers 24 positioned in the cooling chamber 23. As
will be noted, the beverage containers 24 preferably comprise
blow-molded, comparatively inexpensive plastic receptacles of the
disposable type which are commonly used by dairies to package fluid
milk in 21/2 gal. quantities. A typical example of this type of
faucet-equipped, disposable plastic beverage container is shown in
U.S. Pat. No. 3,430,824 issued Mar. 4, 1969 to Conners et al.
As seen particularly in FIGS. 1 and 5, the walls of the inner liner
or shell 17 which define the cooling chamber 23 and the inner wall
of the closure panel 25 are designed and constructed to generally
conform to and support a pair of these beverage containers 24 with
the faucets 30 thereof projecting outwardly through openings
defined by the arcuate or semi-circular recesses 28 formed in the
lower edge 27 of the closure panel 25 and a pair of complemental
arcuate recesses 31 formed in the lower mounting flange 17a of the
inner liner or shell 17. This arrangement provides exterior access
to and for manipulation of the ported valve cock elements 32 which
are slidable axially within the stationary barrel portions 29 of
the faucets 30 to control the outflow of beverage from the
containers 24.
Mounted beneath the lower edge 27 of the closure panel 25 and in a
pair of adjacent recesses 33 and 34 formed in the front wall of the
cabinet are a pair of stirrup-shaped faucet actuators 35 and 36.
The right hand actuator 36 is a mirror image of the left hand
actuator 35 which will now be described in detail. The actuator 35
preferably comprises a sheet metal strap or stamping formed with a
horizontal crosspiece or bight portion 37 and a pair of integral,
down-turned legs 38 and 39. The leg 39 is provided toward its lower
end with a laterally outwardly projecting trunnion 40 which is
journalled for rotation or pivoting movement in an opening 41
formed in the adjacent wall of cabinet. The leg 38 is also provided
toward its lower end with a laterally projecting trunnion 42 which
extends through an opening 43 formed in the opposite side wall of
the recess 33. Operatively connected with the trunnion 42 is a
coaxial torsion spring assembly 44 arranged to resiliently bias the
actuator 35 toward its inward, valveclosing position as shown by
full lines in the several views of the drawings. The torsion spring
assembly 44, however, permits the actuator 35 to be moved manually
against spring pressure to a valve-opening position as shown by
broken lines in FIG. 5. As shown particularly in FIG. 4, the
crosspiece or bight portion 37 of the actuator 35 is formed in its
rearward or inner edge with a generally T-shaped slot 45 adapted to
receive and confine therein the diametrically enlarged, flat head
portion 46 of the slidable valve cock 32 of the faucet 30. As will
be understood, the enlarged head portions 46 of the faucet valves
30 of the beverage containers 24 are simply slipped downwardly into
the slots 45 of the actuators 35 and 36 when the containers 24 are
initially placed in the cooling chamber 23 and when the closure
panel is removed. When the closure panel is replaced, its recessed
or notched lower edge portion 27 securely holds the necks or
barrels 29 of the faucets in position where the enlarged heads 46
of the valve cocks are held in the slots 45 of the actuators. The
forward edges of the faucet actuators preferably include one or
more upturned handle tabs 47 to facilitate the manual manipulation
thereof.
The lower front wall portion of the cabinet 10 is also recessed to
define therein a well 48 beneath the faucets 30 of the beverage
containers. The well 48 provides sufficient space beneath each
faucet 30 to position a drinking cup or other receptacle to catch
water or other beverage discharged from the faucets when they are
opened by their actuators. A shallow drain receptor tray 49 is
removably positioned at the bottom of the well 48 to collect
spillage therein.
Referring again to FIG. 1, it will be noted that the condensate
drain trough 21 formed in the bottom wall of the cooling chamber 23
is provided in its central region with a funnel-shaped drain outlet
50 to which is connected the upper end of a drainage tube 51. The
drainage tube 51 extends downwardly through an opening 52 formed in
a diagonal fairing plate 53 disposed at the top of the well 48, so
as to discharge condensates initially collected in the trough 21 to
the receptor tray 49 positioned in the bottom of the well 48.
The operation of the present beverage cooler is believed readily
apparent. However, when it is desired to use the cooler, at least
one, and preferably two, of the containers 24 are placed in the
cooling chamber 23 by first unfastening the flexible plastic latch
26 and removing the closure panel 25 to gain free access to the
cooling chamber from the front opening thereof. The containers 24
are placed in the cooling chamber so that the stationary barrel
portions 29 of their faucets 30 rest in the semicircular recesses
31 formed in the flange 17a (see FIG. 5), and the enlarged heads 46
are engaged in the T-shaped slots 45 of the faucet actuators 35 and
36. The closure panel is then replaced to close the cooling chamber
and securely locked in position by the latch 26.
Energization of the refrigeration system, which is normally
thermostatically controlled, functions to circulate a refrigerant
through the cooling coils 14 and thus cool the contents of the
cooling chamber 23. When it is desired to discharge beverage from
the cooler, either one or the other of the actuators 35 and 36 may
be manually pivoted outwardly to move the ported valve cock element
32 axially outwardly from the barrel portion 29 of the faucet (see
broken lines FIG. 5), and thus permit the beverage to flow by
gravity outwardly and downwardly from the faucet into a cup or
other receptacle held within the recessed front wall of the cabinet
beneath the faucet. The torsion spring assembly 44 associated with
each of the faucet actuators will function to return the actuator
and faucet to their closed positions upon release of the actuator
to thus minimize spillage. When either or both of the beverage
containers have been emptied, they may be readily and easily
replaced with full containers simply by removing the closure panel
25 to thus gain access to the cooling chamber.
As will be apparent, the present cooler may be used in the home,
office, restaurant, or any other populated area to refrigerate and
dispense potable water or substantially any other liquid beverage
packaged within the disposable type plastic container without
requiring transfer of the beverage from the packaging container
into the cooler structure.
While a single preferred embodiment of the invention has been
illustrated and described in detail, it will be understood that
various modifications in details of construction and design are
possible without departing from the spirit of the invention or the
scope of the following claims.
