Referring to the drawings, and more particularly to FIGS. 1 through
4, 14 generally designates an improved double compartment thermally
insulated container constructed in accordance with the present
invention.
The container 14 comprises a generally cylindrical casing 15 of
suitable rigid material, such as metal, plastic or the like,
provided with a screw-threaded bottom cap 16, said cap having an
internally threaded skirt portion 17 which is threadedly engagable
with a correspondingly externally threaded lower end portion of the
casing 15 in the manner illustrated in FIG. 2. The casing is
provided with the convergent top end portion 18 and with external
threads 19 immediately subjacent the convergent top portion 18. A
cup member 20 is threadedly engagable with the threads 19 in the
manner illustrated in FIG. 2, thereby providing a top closure for
the casing 15. A second cup member 21 is nestable inside the first
cup member 20 in the manner illustrated in FIG. 2.
The casing 15 is provided with a central diametrical partition wall
22 which may be integrally molded with the casing 15 or may be
otherwise rigidly secured therein. This defines two generally
semi-cylindrical compartments in the casing. Disposed in each of
said compartments is a glass or other suitable receptacle 23 which
generally conforms in shape with the inside shape of the associated
compartment but which is supported in the compartment to define an
air space 24 between the container 23 and the wall surfaces of the
compartment. Thus, as shown in FIG. 2, bottom spacers 25, 25 of
suitable heat-insulating material, such as plastic material or the
like, are provided in the bottoms of the two respective
compartments, said bottom spacers 25 conforming in shape with the
bottom portions of the compartments and extending upwardly
sufficiently to engage between the wall portions of the walls of
the receptacles 23 and the adjacent wall surfaces of casing 15 and
partition wall 22. As shown in FIG. 2, the spacer members 25 rest
on the bottom cap 16, and additional spacer blocks 26, 26 are
provided between the bottoms of members 25 and the bottoms of the
receptacles 23.
The blocks 26 may be of any suitable heat-insulating material, such
as rubber, plastic, or the like, and may have a substantial degree
of resiliency so that they act as compressible springs.
Each receptacle 23 is formed with a semi-circular mouth or rim 28
which is offset inwardly relative to the convergent upper portion
29 of the receptacle, as shown at 30. The top of casing portion 18
is formed with an inturned flange 31, and the top edge of the
partition wall 22 is likewise formed with inturned flanged portions
32, 32 whereby an inturned peripheral flange is defined at the top
end of each of the beverage receptacle compartments in the casing.
A resilient deformable sealing gasket 33 is provided between the
rim 28 of each receptacle 23 and the flanged opening adjacent
thereto defined by the inturned flanged elements 31, 32 associated
with each of the beverage receptacle compartments. Thus, the top
sealing gaskets 33 and the bottom spacer members 25 support the
receptacles 23, in cooperation with the blocks 26, so as to
maintain a substantially continuous air space 24 between each
beverage receptacle 23 and the surrounding wall of casing 15 and
partition wall 22 in the compartments defined by casing 15 and
partition wall 22.
The top of each beverage receptacle 23 is provided with a resilient
deformable stopper 35 of generally semi-circular shape adapted to
sealingly engage in the mouth of the receptacle in the manner
illustrated in FIG. 2. Each stopper 35 is provided with a flanged
top portion 36 limiting its insertion into the associated
receptacle mouth, the tops of the stoppers 35 being engagable by a
cover cap 37 threadedly engagable on the top of the convergent
portion 18 of casing 15, as illustrated in FIG. 2. Thus, the cover
cap 37 is threadedly engagable on the top end of convergent casing
portion 18 and when tightened, exerts downward clamping pressure on
the flanged stoppers 35, 35. The clamping force exerted by the cap
37 is transmitted through the stoppers 35 and the receptacle 23 to
the bottom resilient cushioning blocks 26, 26, thus resiliently
clamping the receptacles 23, 23 and providing them with cushioned
support so that they are protected against breakage, for example,
when the assembly is accidentally dropped or jarred.
The spacer members 25, which are of generally cup-like shape, are
preferably of suitable resilient material, such as rubber,
resilient plastic material, or the like, to provide shock-absorbing
effects, in cooperation with the blocks 26. If the spacer members
25 are of rubber or other similar resilient deformable material,
the blocks 26 may be of substantially rigid construction.
It will be readily apparent that the receptacle 23 may contain two
different liquids, for example, a hot liquid in one and a cold
liquid in the other, and that access to said liquids may be
obtained independently, since each receptacle 23 has its own
independent stopper 35. It will be further apparent that the
receptacles 23 may be readily removed for cleaning, or the like, by
merely unscrewing the bottom cap 16, which allows the receptacles
23 to be then withdrawn from their associated compartments. When
removing the receptacles, the cups 20 and 21 are removed, after
which the cap 37 is detached, and the stoppers 35 are removed. The
bottom cap 16 is then unscrewed and the spacer members 25 and 26
are removed, thereby providing access to the bottom portions of the
receptacle 23. The receptacles 23 may then be removed by pushing
them inwardly at their mouth portions, which forces them out
through the open bottom end of casing 15. The receptacles, after
cleaning, may be replaced by following a reverse procedure.
Referring now to FIGS. 5 through 8, the structure therein disclosed
is somewhat similar to the form of the invention illustrated in
FIGS. 1 through 4, except that the main casing, shown at 15', does
not have a removable bottom cap, but is instead provided with an
integral bottom wall 16'. The inner receptacles, shown at 23',23'
are generally semi-cylindrical in shape and rest on the bottom
spacer blocks 26,26. The main casing 15' is provided with a top
bushing member 80 having an externally threaded outwardly
projecting intermediate annular rib 81 with which the outer cup,
shown at 20' is threadedly engagable. The bushing member 80 has an
externally threaded depending lower portion 82 and an externally
threaded top portion 83. Lower portion 82 is threadedly engaged in
the top portion of main casing 15' with the top rim of casing 15'
in abutment with rib 81. A cover cap 84 is threadedly engaged on
the top bushing portion 83. An auxiliary cup 21' is nestingly
received between cap 84 and outer cup 21', as shown. The bushing
member 80 is provided with an inwardly projecting annular rib 31'
subjacent top portion 83. A single integral double gasket 33' is
interposed between the rim portions 28' of the receptacles 23' and
the inwardly projecting rib 31' of the bushing member 80. The
gasket 33' is provided with the central diametrical thickened
portion 40 which is engaged between the flat portions of the rims
28', shown at 41,41. The central gasket portion 40 is provided with
a bottom groove which receives the top edge of the diametrical
central partition wall 22' of casing 15'. As shown in FIG. 6, the
inner cup or cap 84 exerts downward clamping pressure on the
resilient deformable stoppers 35' in the same manner as the cover
cap 37 in the previously described embodiment of the invention, and
thereby resiliently clamps the receptacles 23' against the spacer
members 26, which may be of resilient deformable material, as
above-mentioned, to provide cushioned support for the receptacles
23', 23'.
As shown in FIG. 6, the rim portions of the receptacles 23' are
provided with outwardly projecting stop ribs 42 to limit the
downward displacement of the gasket 33' relative to the mouth
portions of the receptacles.
To remove receptacles 23' for cleaning, it is merely necessary to
uncover the container, namely, by unscrewing the caps 20' and 84,
removing the stoppers 35' and then reaching downwardly into the
receptacles 23' and pulling them upwardly out of casing 15'. The
basket 33' will follow the receptacles and may be detached to allow
the receptacles to be separately cleaned. The container may be
reassembled by following a reverse procedure.
FIG. 9 illustrates another form of the invention wherein respective
thermally insulated containers of identical construction, shown at
46, 46 are detachably secured together in axial alignment and in
end-to-end relationship by means of a connecting sleeve member 47.
Thus, each container 46 is of substantially conventional thermally
insulated construction and is provided with a covering cup 48 which
has internal threads engaged with external threads 49 provided on
the casing of the container 46. Each container is provided with a
reduced bottom end portion having external threads 50.
Each cup 48 is provided with a reduced top end portion, as viewed
in FIG. 9, having external threads 51. The connecting sleeve 47 has
an intermediate horizontal partition wall 52, the portion above
wall 52 having internal threads 53 which are threadedly engagable
with the threads 50 of a thermos container 46 and the lower portion
of the sleeve below 64 partition wall 52 having internal threads 54
which are threadedly engageable with the reduced threaded portion
51 of a cup 48. Thus, a pair of thermally insulated containers 46,
46 may be connected together by the provision of a sleeve 47
engaged on the threaded cup portion 51 of the lower container with
the threaded portion 50 of the upper container threadedly engaged
with the threads 53 in the upper portion of sleeve 47, as shown in
FIG. 9.
As above-mentioned, in the arrangement of FIG. 9, the respective
thermally insulated containers 46 are of generally conventional
construction and are provided with their normal cover caps 55,
which are receivable in the reduced upper portions of the cups 48,
in the positions of the cups illustrated in FIG. 9.
Obviously, by employing the required number of connector sleeves
47, any number of thermally insulated containers 46 may be
connected in end-to-end relationship, thereby providing for a
corresponding number of different beverages to be stored.
FIGS. 10 and 11 disclose a further embodiment of the present
invention wherein the multiple compartment thermally insulated
container is in the form of a double compartment thermally
insulated jug whose internal construction is generally similar to
that illustrated in FIGS. 1, 2, 3 and 4, except that the container
is of substantially greater volume and is provided with a cover cap
60, which corresponds to the cover cap 37 employed in the
embodiment of FIGS. 1 through 4. The container of FIGS. 10 and 11,
which is designated generally at 61, therefore comprises a main
casing 62 having the reduced neck portion 63 and having the
removable bottom cover cap 64 which is threadedly engaged on the
lower end portion of casing 62. The top cover 60 is threadedly
engaged on the upper portion of the reduced neck 63. Disposed in
the casing 62 are the respective substantially semi-cylindrical
beverage receptacles 65,65 which are located in respective
compartments defined on opposite sides of a central diametral
partition wall 66, similar to the partition wall 22 in the
embodiment of FIGS. 1 through 4. The receptacles 65 have reduced,
generally semi-cylindrical top portions 67, a suitable gasket means
similar to the gaskets 33,33 may be employed to seal the top
portion of the respective air spaces defined between the receptacle
65 and the inside wall surfaces of casing 62 and partition wall 66.
Likewise, suitable spacing elements, such as the elements 25 and 26
of FIGS. 1 through 4 may be employed in the bottom portions of the
respective compartments to support the bottom ends of the container
65 and to maintain the air space between each receptacle and the
adjacent wall surfaces of casing 62 and transverse partition wall
66.
Connected to the lower portion of each receptacle 65 and extending
through diametrically opposite portions of casing 62 are respective
spigot assemblies 68, 68 for dispensing the liquids contained in
the receptacles 65. The spigot assemblies 68 are suitably rigidly
secured to opposite portions of the wall of casing 62.
Each receptacle 65 is provided with a suitable stopper which is
sealingly engagable in its mouth, for example, with a stopper such
as that illustrated in FIG. 12 or 13. Thus, the stopper of FIG. 12,
shown generally at 69, may comprise a bottom semi-circular plate
member 70 adapted to be received in the generally semi-circular
mouth of a receptacle 65 in the manner shown in FIG. 12A. The plate
member 70 is provided with an upstanding vertical arm 71 projecting
perpendicularly therefrom at its intermediate portion, the arm
extending through an aperture 72 in the intermediate portion of a
generally semi-circular top plate 73 which is substantially larger
than the bottom plate 70 and which is adapted to overlie and be
supported on the top rim of the reduced top portion 67 of the
associated receptacle 65 in the manner shown in FIG. 13. The bottom
plate 70 is formed to define a generally semi-circular seat 74 at
its periphery on which is engaged a correspondingly shaped
resilient deformable gasket ring 75 whose top surface is engaged by
the plate member 73. Pivoted at 76 to the top end of the arm 71 is
a cam lever 77, said lever having a pair of depending cam-shaped
legs 78, 78 disposed on opposite sides of the arm 71 and pivotally
connected thereto at 76 by a transverse pivot pin. As shown in FIG.
13, the pivotal connection 76 is eccentrically located with
reference to the camming edge portions of the parallel cam elements
78, 78, said edge portions having flat detent portions 80' at a
substantially larger radial distance from the pivotal connection 76
than the lower end of the lever 77 as viewed in FIG. 13. Thus, when
the lever 77 is rotated from the upstanding position thereof shown
in FIG. 13 to a horizontal position, such as shown at the right
side of the lower portion of FIG. 12, the associated lower plate
element 70 is pulled upwardly to compress the associated gasket
ring 75 and to deform said gasket ring outwardly with sealing
force, causing the gasket to sealingly engage the inside surface of
the adjacent top receptacle portion 67. The lever 77 is locked in
sealing position, namely, in a horizontal position, by the locking
engagement of the flat edge portions 80' of its cam elements 78
with the top plate member 73, as is illustrated at the right side
of the lower portion of FIG. 12.
Therefore, it will be readily apparent that whenever it is desired
to dispense liquid from either receptacle 65, the top cap is
removed and the stopper 69 associated with the receptacle from
which the desired beverage is to be dispensed is released, allowing
the liquid to flow from the associated spigot 68. As shown in FIG.
12, the stopper 69 may be released by rotating its locking lever 77
to an upright position, which relaxes the compressive force on its
sealing gasket 75 and therefore allows the stopper assembly to be
lifted upwardly and to be disengaged from the mouth of the
associated receptacle 65. The stopper may be replaced by employing
a reverse procedure.
FIG. 13 illustrates another form of stopper, shown generally at 90,
which may be employed in accordance with the present invention. The
stopper 90 comprises a generally semicylindrical main body 91 of
molded plastic material having an integral peripheral top flange
92. A flat rubber gasket 93 is provided beneath flange 92. Another
rubber gasket 94 is suitably cemented to the periphery of body 91
at its intermediate portion, as shown in FIG. 13A.
The stoppers 90 may be used in place of the stoppers 35' of FIG. 5,
or in place of the stoppers 35 of FIG. 2, as well as in the form of
the invention illustrated in FIGS. 10 and 11.
While certain specific embodiments of an improved multiple
compartment thermally insulated container have been disclosed in
the foregoing description, it will be understood that various
modifications within the spirit of the invention may occur to those
skilled in the art. Therefore, it is intended that no limitations
be placed on the invention except as defined by the scope of the
appended claims.
