Detailed Description
Referring generally to FIGS. 1-4, there is illustrated a container test system 10 to assess
insulative performance of a container C (FIGS. 1-2). In general, the system 10 may include a
support structure 12 to support other portions of the system 10, a source 14 ( of cooled
liquid for filling the container C, a test assembly 16 in which the container C is tested and in
fluid communication with the cooled liquid source 14, and various mechanical and electrical
utilities 18 ( coupled to the test assembly 16 and/or to the cooled liquid source 14 to
facilitate testing of the container C. The system 10 may be coupled to external utility sources
(not separately shown), for example, a generator or utility power supply, telecommunication
services, water supply, waste drain, and any other suitable utility sources. Also, the system 10
may include any suitable fluid conduit, cables, wires, valves, check valves, or any other suitable
elements that may not be illustrated in the drawings for clarity.
The support structure 12 may include framework or a chassis 20, and adjustable feet 22
on which the chassis 20 is carried. The support structure 12 may include a test bay 24 for testing
the container C, a cooler bay 26 that may be located below and to the side of the test bay 24 for
carrying coolant, and a mechanical and electrical utility bay 28 above the cooler bay 26 for
carrying the various mechanical and electrical sub-systems to support the test assembly 16. The
support structure 12 also may include exterior panels 30 carried by the chassis 20, handles 32 for
handling the chassis 20 and/or the panels 30, and bracketry/shelving 34 to carry various portions
of the system 10. For example, a container access panel 31 may include a handle 33 at one end
for removing the panel 31 and gaining access to the test bay 24. Also, as shown in the
support structure 12 may include internal panels or walls 36, for instance, to separate the utility
bay 28 from the test bay 24. The structure 12 also may include various ventilation apertures 38
in the walls 36 and/or the shelving 34.
With reference to the cooled liquid source 14 may include a cooler to carry a
cooled liquid used in carrying out testing. In one embodiment, the cooled liquid may include
water and, more specifically, may include a solvent mixture. For example, the cooled liquid may
include a mixture of 95% water and 5% isopropyl alcohol. In other embodiments, the cooled
liquid may include beer, wine, liquor, or any other suitable liquid. The source 14 may carry a
coolant to cool the liquid. For instance, the source 14 may carry the liquid in a manner
surrounded by the coolant, or vice-versa, with any suitable wall(s), tubing, or any other suitable
barrier(s) therebetween. In one embodiment, the coolant may include ice. For example, the
coolant may include ice and salt, or a salt/ice bath. In other embodiments, the coolant may
include ice water, dry ice, or any other suitable coolant. In still other embodiments, the coolant
may include a refrigerant, wherein the source 14 may include a refrigeration apparatus. A cooled
liquid temperature sensor (not separately shown) may be coupled to the cooled liquid source 14
to measure the temperature of the cooled liquid and may be communicated to the utilities 18.
In any case, the storage temperature of the cooled liquid at the source 14 may range from
-10 to 50 degrees Celsius, and the operational temperature of the cooled liquid in the container C
may range from 0 to 40 degrees Celsius. Preferably, the temperature of the cooled liquid in the
source 14 may be below a desired test temperature of the cooled liquid in the container C, for
example, 2 to 4 degrees Celsius below, to account for heat transfer during delivery therebetween.
More specifically, a desired temperature of the cooled liquid at the source 14 for delivery into the
container C may be about -3 degrees Celsius so that, for instance, testing of the container C may
begin at about 0 degrees Celsius.
With reference to FIGS. 3 and 4, the utility bay 28 may carry a computer subsystem,
which may include a controller 40 and a graphical user interface 42 coupled to the controller 40.
The controller 40 may include, for example, a National Instruments (NI) cRIO-9075 controller,
or any other suitable device(s). The interface 42 may include, for instance, an APC 18W5 touch
panel computer, or any other suitable device(s). The bay 28 also may include any other suitable
utilities for carrying out container testing. For example, the bay 28 may include one or more
metering pumps 44, for instance, a peristaltic pump, which may be a computer-
compatible/programmable digital drive pump, for instance, a Masterflex L/S 07551-00 pump.
Also, the bay 28 may include one or more stirring pumps 46, for instance, a Hagen AquaClear 5
pump. Further, although not separately shown, the bay 28 may include sensor interfaces, for
instance, an NI USB 9213 interface, and a digital to analog converter, for instance, a NI 9403
module. Further, as shown in the utility bay 28 may include one or more exhaust fans
48, which may be carried by a panel 30 corresponding to the bay 28.
As shown in the bay 28 may include interior panels 36 and shelves 34 with
ventilation apertures 38 therethrough. More specifically, a vertical panel 36 may include a
ventilation aperture 38 in communication between the test assembly bay 24 and the utility bay
28, and a horizontal panel or shelf 34 may include a ventilation aperture 38 in communication
between the cooler bay 26 and the utility bay 28. Accordingly, the exhaust fans 48 may operate
to pull cooler air from the test bay 24 and/or the cooler bay 26, through the utility bay 28, and out
of the utility bay 28 to the exterior of the system 10.
With reference to the test assembly 16 may include a test chamber 50 including
an air inlet 52, an air outlet 54 downstream of the air inlet 52, and a container location 56
between the inlet 52 and the outlet 54. The test assembly 16 further may include a fan 58 to
generate airflow between the upstream inlet 52 and the downstream outlet 54, and/or one or more
climate controllers 60 to control the climate in the test chamber 50. For example, the climate
controller(s) 60 may be located upstream of the container location 56 and may heat and/or cool
air. The fan 58 may be located at an upstream end of the test chamber 50, for example, as shown
in the drawings, upstream of the climate controller(s) 60. In other embodiments the fan 58 may
be located at a downstream end of the test chamber 50 or anywhere midstream between the
upstream and downstream ends. Any suitable fan may be used, and the fan 58 may be powered
by a BK Precision 1696 power supply, and fan speed may be monitored via a Newport P6001A
frequency meter. The climate controller(s) 60 may include a heater, for example, a KLC
Corporation MSH70S heater, or any other suitable heater. In other embodiments, the
climate controller(s) 60 also or instead may include a chiller, vortex cooler, or any suitable
refrigeration apparatus. The fan 58 and climate controller(s) 60 may be powered via any suitable
power distributors, relays, and/or the like, which may be located in the test bay 24 and/or the
utility bay 28 (. In other embodiments, although not illustrated, the climate controller(s)
60 instead may include portions in direct contact with the container C, for example, resistive
heaters or the like.
Also, with reference to FIGS. 5 and 6, the test chamber 50 may include an airflow
conduit 62 between the upstream inlet 52 and the downstream outlet 54 to convey air to, around,
and past the container location 56. Likewise, a container conduit 64 may intersect the airflow
conduit 62 between the upstream inlet 52 and the downstream outlet 54 and may carry the
container C therein at the container location 56. The conduits 62, 64 may include tubing, pipe,
or the like, which may be composed of glass, plastic, or any other suitable material and may be
cylindrical or of any other suitable shape. The conduits 62, 64 may be translucent, preferably,
transparent, as illustrated to facilitate viewing of container testing. The conduits 62, 64 may be
sealed to one another and, for example, may be welded, adhered, fastened, or otherwise coupled
together to provide the test chamber 50 in a sealed configuration.
With reference to the test assembly 16 also may include one or more locators
66a,b and, for example, may include multiple sets of first and second locators for different
container sizes. For instance, the assembly 16 may include a first locator 66a to locate a base of
the container C in the test chamber 50, and a second locator 66b to locate another portion of the
container C in the chamber 50. For example, the locator 66b may locate a shoulder and/or one or
more other portions of the container C, for instance, a neck portion and/or a body portion. The
first locator 66a may include one or more feet 70 and a perforated plate (not separately shown)
from which the feet 70 may extend. Likewise, the second locator 66b may include
circumferentially spaced, radially extending locator ribs 71 that may be carried on an
undersurface of a plate 73 for radial engagement with an exterior surface, for example, of a neck
finish, of the container C.
Additionally, lower and upper frustoconical bodies 72a, 72b may disposed around
portions of the container C, for example, to serve as masks to deflect airflow and selectively
confine exposure of only desired portions of the exterior surface of the container C to the heated
air. For instance, this arrangement may replicate heat transfer from a consumer’s hand grip on a
body portion of the container C. The frustoconical bodies 72a, 72b may be puck-like
components having exterior surfaces corresponding to interior surfaces of the conduit 64, and
hollow interiors for contacting the container C. An interior 68a of one of the bodies 72a may be
a pocket and an interior 68b of another one of the bodies 72b may be a through passage. The
upper frustoconical body 72b may include a seal groove 74 for carrying a seal (not shown) for
sealed coupling to the conduit 64. Similarly, the lower frustoconical body 72a may include a
seal groove and seal (not shown). The locators 66a,b and bodies 72a,b may be replaced by larger
or smaller locators and bodies to accommodate larger or smaller containers.
With reference to FIGS. 5 and 6, the system 10 also may include a positioning stage 76 to
position the container C with respect to the test chamber 50. The stage 76 may include a manual
screw jack, for example, as illustrated, a servo ball screw, or any other suitable positioning stage
to move the container C. The feet 70 of the first locator 66a may rest on top of the stage 76.
Accordingly, smaller and larger sized containers may be accommodated.
With reference to the test assembly 16 also may include one or more air
temperature sensors, for example, in a sensor array. An ambient air temperature sensor 78 may
be located in any suitable location in the test bay 24. The sensors also may include, for example,
at least one upstream temperature sensor 80a upstream of the container location 56, at least one
downstream temperature sensor 80b downstream of the container location 56, and one or more
midstream temperature sensors 80c-f, adjacent to the container location 56 between the upstream
and downstream temperature sensors 80a,b. The upstream temperature sensor 80a may be
located between the container location 56 and the inlet 52. The downstream temperature sensor
80b may be located between the container location 56 and the outlet 54.
The midstream temperature sensors 80c-f may include one or more temperature sensors
on opposite sides of the test chamber. For example, one or more upper sensors 80c and/or 80d
and one or more lower sensors 80e and/or 80f may be located on opposite sides of the container
location 56. The upstream and downstream temperature sensors 80a,b may include probes or
other portions that extend into the test chamber 50 and that also may extend across a central
longitudinal axis L of the chamber 50. The midstream temperature sensors 80c-f may include
probes or other portions that extend into the test chamber 50 and to a position configured to be
adjacent an exterior surface of the container C. For example, free ends of sensor probes may
terminate within five millimeters (mm) from the exterior surface of the container C and, more
specifically, within 2 mm thereof but not touching the container C. As illustrated, the sensors
80a-f may include adjustment couplings 82 to allow the sensors 80a-f to be advanced and
retracted to desired positions in the test chamber 50. The couplings 82 may include mechanical
sub-assemblies that, when adjusted, compress an outer sheath of the sensors 80a-f, locking the
sensors 80a-f in their intended positions relative to the container C. In any case, the sensors 80a-
f may extend through corresponding apertures of the conduit 62.
With reference to the test assembly 16 also may include a test probe head 84 for
coupling to the container C and providing fluid flow to and from the container C and for
obtaining temperatures in the interior of the container C. The test probe head 84 may include a
probe head locator 86 to locate other portions of the test probe head 84 with respect to other
portions of the test assembly 16 and/or the container C. The probe head locator 86 may include a
puck-like component having a radially outermost exterior 87 to contact a corresponding portion
of the test assembly 16, for example, the inside of the container conduit 64 (. The probe
head locator 86 also may include a through passage that may extend along a transverse axis T for
carrying other portions of the test probe head 84.
For example, and with reference to the test probe head 84 may locate and retain a
test probe assembly 88, which may include a handle 89 coupling to a utility conduit 90 and
having a through passage for communicating various utility components therethrough. For
example, the utility conduit 90 may include any suitable tube(s), hose(s), cable(s), wire(s), and/or
the like. The probe assembly 88 also may include at least one fluid conduit 92 extending through
and carried by the handle 89, at least one means of stirring the fluid contents, a plurality of
axially spaced supports 94 coupled to the conduit 92, and a plurality of liquid temperature
sensors 96a-g.
The temperature sensors 96a-g may be arranged in a circumferentially and axially spaced
array. For example, the sensors 96a-g include axial ends or sensing portions located at a
plurality of different levels spaced axially and circumferentially apart from one another, and that
may correspond to each of the supports 94. More specifically, the sensing portions may be
spaced about one inch intervals, plus or minus half an inch. In the illustrated example, the
sensing portions may extend past respective supports for up to a few millimeters. Accordingly,
the sensors 96a-f may be circumferentially and axially spaced about the probe assembly 88, for
example, about the transverse axis T. The sensors 96a-g may include 30AWG wires carried by
probe tubes that may be carried by the supports 94.
The fluid conduit 92 may include a liquid delivery and extraction conduit 91, and may
include a separate liquid agitation conduit 93. The liquid delivery and extraction conduit 91 may
include a serrated or otherwise relieved end 91a to facilitate extraction, and the liquid agitation
conduit 93 may include an end 93a that is spaced axially shy of the end 91a of the other conduit
91. In other embodiments, the conduits 91, 93 may be a single, unitary conduit coupled to any
suitable upstream valves, conduit, pumps, and/or the like.
A method of assessing insulative properties of a container may include the following
steps, with general reference to the drawing figures as just one of many possible examples of
systems to carry out the method.
A container may be positioned in a test chamber. For example, the container C of
may be positioned in the test chamber 50 of More specifically, the access panel 31 ( may be removed and the container C inserted into an open end of the container conduit 64
( and located therein using the locators 66a,b. Moreover, the probe head 84 may be
lowered into the container conduit 64 so that the test probe assembly 88 ( locates within
the container C, but the conduit 92 and the sensors 96a-g do not contact the inside surfaces of the
container C.
Thereafter, the container C may be thermally preconditioned, or thermally soaked. In one
embodiment, the climate controller(s) 60 may precondition the container C, for example, by
providing the test chamber with cold air, for instance, between 30°C and 35°C. This
embodiment may be used alone or in addition to the embodiment described hereafter. In another
embodiment, cooled liquid may be cycled through the container C to at least one level. The
cycling may include delivering the cooled liquid from the source 14 of the cooled liquid to the at
least one level inside of the container C, waiting for a period of time, and then extracting the
liquid from the inside of the container C. For example, the cooled liquid may be delivered from
the cooled liquid source 14 by the liquid pump 44, through the test probe head 84 and the test
probe assembly 88, and into the container C. The period of time may be, for example, between
0.001 and 180 seconds, including any ranges and sub-ranges therebetween. The liquid may be
extracted by the liquid pump 44 from inside the container C, through the test probe assembly 88
and test probe head 84, and to a system drain chamber or external waste drain (not shown). The
preconditioning step may include any suitable quantity of cycles, for instance, in correspondence
to the quantity (n) of the liquid temperature sensors 96a-g. For example, the preconditioning
cycles may include n, n-1, or any other suitable quantity of cycles. Alternatively, the number of
cycles may be two, three, or any other suitable quantity, for instance, where the difference in
liquid temperature in the container C from cycle to cycle falls below some predetermined
acceptable value (e.g., about 3°C) sufficient to begin testing.
Subsequently, the container C may be filled with cooled liquid by delivering the cooled
liquid from the cooled liquid source 14 until the cooled liquid reaches a fill level in the container
C. For example, the liquid pump 44 may deliver the cooled liquid from the source 14 to the
container C until the cooled liquid reaches a fill capacity for the container C. For example, if the
container is a 12 oz. bottle, then the fill capacity may be 12 ounces, plus or minus production
tolerances well known to those of ordinary skill in the art.
At any suitable time, the outside of the container C may be thermally treated, for
example, by using the climate controller(s) 60 to control the climate in the chamber. For
example, heat or cold may be applied continuously, or progressively, for instance, in a periodic
step-wise manner. For example, in the illustrated embodiment, this step may include thermally
treating air with the climate controller(s) 60 and flowing the air past the climate controller(s) 60
and toward the container C. More specifically, the climate controller(s) 60 may be activated and
the fan 58 may be activated to move heated air through the test chamber 50. In other examples,
any other suitable heating techniques may be used, including using induction heating, laser
heating, or any other suitable manner of heating the outside of the container C.
Further, at any suitable time, temperature of the air outside the container C may be
measured. This step may include measuring a plurality of temperatures of the air, including an
upstream air temperature, a downstream air temperature, and/or a midstream air temperature
proximate the container. For example, one or more of the air temperature sensors 80a-f in the
test chamber 50 may be monitored by the computer sub-system to measure the air temperature.
Also, at any suitable time, temperature of the liquid inside the container C may be
measured. This step may include measuring a plurality of temperatures of the liquid at different
levels within the container C. For example, the temperature sensors 96a-g of the probe assembly
88 may be monitored by the computer sub-system to measure the liquid temperature. The
temperature may be measured during the preconditioning step, for instance, for use as fill level
indicators. More specifically, levels of liquid inside the container C, for example, at each of the
supports 94, can be determined using the corresponding temperature sensors 96a-g
corresponding to each of those supports 94. Each of the corresponding temperature sensors 96a-g
may report its temperature at intervals greater than or equal to 0.001 seconds, creating a real-time
reporting of the temperature at that sensor location.
The fill level of the container C may be determined via other embodiments. For example,
the uppermost temperature sensor 96g may be a fill level switch instead of a temperature sensor.
In another embodiment, a fill level of the container C may be determined by weight, via one or
more load cells (not shown) that may be disposed beneath the container C in any suitable manner
and communicated in any suitable manner to the controller 40. In yet another embodiment, a
flow meter (not shown) may be in fluid communication between the pump(s) 44 and the
container C and communicated in any suitable manner to the controller 40.
The liquid temperature measurements may be plotted and output to the user interface 42
at any suitable time intervals after the test is initiated, for example, at 6, 7, 8, 9, etc. minutes after
a test cycle is initiated. Accordingly, plots taken from testing of different containers of various
geometries and compositions can be compared and contrasted to assess relative insulative
performance of the different containers. The plots may demonstrate changes in temperature over
changes in time. The containers may be tested with or without labels or other elements carried
by the containers.
One or more additional steps may be provided to simulate consumption of the liquid by a
consumer. For example, the method further may include the step of extracting liquid from the
container C while continuing to measure temperature of the liquid in the container C. The liquid
may be extracted continuously, or progressively, for instance, in a periodic step-wise manner.
Also, the method may include the step of agitating the liquid in the container C, at any suitable
time. The agitation of the liquid within the container may occur continuously, or progressively,
for instance, in a periodic step-wise manner. For instance, the air pump 46 may blow air into the
container C via the liquid agitation conduit 93 of the test probe assembly 88 and test probe head
84, for example, during the preconditioning step and/or during the steps of measuring the liquid
temperature and/or extracting the liquid. Blowing air into the liquid in the container C may be
used to generate bubbles and stir the liquid in the container C, thus homogenizing the liquid
temperature in the container C because liquid temperatures within the container C may separate
at varying levels.
In general, the computer sub-system mentioned above may be used to carry out various
aspects of the presently disclosed method. In one example, the computer sub-system may
receive input data and instructions from a user, process the received input in light of stored
software and/or data, and transmit output signals to the climate controller, fan(s), pumps, and any
other suitable portions of the system 10. Conversely, in another example, the computer sub-
system may receive input signals from the air temperature sensors 78, 80a-f, the climate
controller(s) 60, the fan 58, the pumps 44, 46, and any other suitable portions of the system 10,
process the received input signals in light of stored data and software, and transmit output data to
