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 r 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 re 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.

The probe head locator 86 also may include a through passage that may extend along a transverse axis T for ng 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 t 90 may include any suitable tube(s), hose(s), cable(s), wire(s), and/or the like. The probe assembly 88 also may e 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 e 30AWG wires d by probe tubes that may be carried by the supports 94.

The fluid conduit 92 may include a liquid delivery and extraction t 91, and may include a separate liquid agitation conduit 93.

In other embodiments, the conduits 91, 93 may be a , unitary conduit coupled to any suitable upstream valves, conduit, pumps, and/or the like.

A method of assessing insulative ties of a container may include the following steps, with general reference to the g 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 ner C inserted into an open end of the ner 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 t the inside surfaces of the container C.

Thereafter, the container C may be thermally preconditioned, or lly 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 ce, between 30°C and 35°C. This embodiment may be used alone or in addition to the embodiment described hereafter. In r ment, 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 ner 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 al 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. atively, 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 , 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 lly 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 ted and the fan 58 may be ted to move heated air through the test chamber 50. In other examples, any other suitable g techniques may be used, including using induction heating, laser g, 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, ing 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 stem 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 ature sensors 96a-g of the probe assembly 88 may be monitored by the computer sub-system to measure the liquid temperature. The ature 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 on.

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 .

In another ment, 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 ller 40. In yet another embodiment, a flow meter (not shown) may be in fluid communication between the ) 44 and the container C and communicated in any suitable manner to the controller 40.

The liquid ature 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 ent 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 e, the method r 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 ing the liquid in the container C, at any suitable time. The agitation of the liquid within the container may occur continuously, or progressively, for ce, 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 ner C because liquid temperatures within the container C may separate at varying levels.

In general, the er 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 e 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 subsystem may receive input signals from the air temperature s 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 ed input signals in light of stored data and software, and transmit output data to the user, for e, via the interface 42.
