The present disclosure relates to a thermometer attached to a beverage container lid and methods of making the same.
With the greater availability of highly efficient vacuum insulated containers, scalding liquids, such as coffee or other hot beverages, placed inside one of these highly efficient containers will stay scalding for long periods of time. In other words, a beverage placed in a vacuum insulated bottle or tumbler at a temperature that is too hot to sip will remain too hot to sip for hours due to the highly efficient insulating constructions that are readily available today. For this reason, it is desirable to know the temperature of the hot liquid before drinking or sipping to prevent scalding one's tongue, lips or mouth. Also, it is likely that a person has a preferable temperature range within which the coffee or other beverage is most thoroughly enjoyed. A thermometer attached to a beverage container lid will facilitate the user to determine this preferable range and then provide the user with feedback to find cooling methods to obtain the desired temperature range. Once attained, the preferred temperature range will be maintained for hours within the previously described insulated container. Along these same lines, a consumer might have a desirable temperature range for cold liquids. Similarly, the thermometer will educate the user to the boundaries of this specific range and measure their effectiveness in achieving the desired range. The thermometer may also provide feedback and educate a user as to preferred techniques available to achieve the desired temperature range whether for cooling or heating the beverage. The education can facilitate future preparation of the desired beverage.
Numerous attempts have been made to identify the temperature of a liquid within a container. These include cups with bottom mounted temperature sensing devices, such as U.S. Pat. No. 6,225,908, entitled “Double Layer Container Equipped With Temperature Warning Device” and U.S. published patent application 2006/0261233 entitled “Spill-Resistant Beverage Contain With Detection and Notification Indicator.” However, in these devices, the temperature of the liquid is not directly measured. Rather, temperature is sensed through the bottom of the container. Similarly, external sleeves have been designed to hold a beverage container and sense temperature through the outside surface of the container. See, for example, U.S. published patent applications 2008/0142529 entitled “Temperature-Indicating Sleeve And Related Container,” 2008/0283538 entitled “Insulated Retainer Having Thermometer For Beverage Container,” and 2008/028562 entitled “Insulated Retainer With Thermometer For Beverage Container.” Another arrangement places the temperature sensor between the walls of a double walled container, for example, U.S. Pat. No. 6,864,462 entitled “Electronic Drinking Mug.” And temperature sensing labels to adhere to the side wall of a container have been proposed. See, U.S. Pat. No. 5,482,373 entitled “Thermometer Indicator for Beverage Container” and U.S. published application 2009/0183669 entitled “Temperature Indicating Label Arrangement and Method.” In the same vein, other designs place a temperature sensor on the outside of the container side wall, for example, U.S. Pat. No. 5,678,925 entitled “Temperature Sensing And Indicating Beverage Mug” and U.S. Pat. No. 6,471,085 entitled “Temperature Cup,” and U.S. published patent application 2006/0207907 entitled “Beverage Container Having A Display.”
Still further designs place a temperature sensor in the inside surface of a beverage container, for example, as shown in U.S. published patent applications 2007/0053406 entitled “Temperature Indicating Container” and 2007/0121702 entitled “Temperature Indicating Container.” Another example is published application WO 2009/037436 in which a clip placed on the side wall of a container, with a first leg containing a temperature sensor that extends into the container and is in contact with the liquid and a second leg that extends outside of the container side wall and provides an audio signal when a desired temperature is reached.
Application WO 2002/101345, entitled “Temperature Indicating Disposable LID For Beverage Container” is directed to an inexpensive disposable lid capable of mass production. Here, a cylindrical cone or protrusion is formed in the lid and extends downwardly into the beverage container. A temperature sensor is positioned at the base of the cone and changes color depending upon the temperature of the liquid. The cone is designed to position the base beneath the surface of the liquid, when the liquid generally fills the container. Thus, the device does not continuously monitor the temperature of the liquid as the liquid is consumed.
U.S. published patent application 2009/0139324 entitled “Liquid Container” is directed to a carafe or container for serving beverages, not an individual container, such as a coffee cup. Here a detecting unit is configured to attach to the open rim of the container and includes a probe that extends into the container to sense temperature of the liquid in the container. An outer package positioned external to the container displays temperature information. U.S. published patent application 2012/0293332 entitled “Temperature Monitoring Beverage Container” is also directed to a carafe or larger container for serving hot beverages. Here, the lid includes a temperature probe that extends into the container and a user interface that includes a temperature display.
