Description

FIELD OF THE INVENTION

This invention relates to an insulated retainer having a thermometer for a beverage container.

BACKGROUND OF THE INVENTION

Beverages housed in cans or bottles are widely consumed, as cold beverages or as hot beverages. Exemplary beverages include soft drinks, juice, cpffee. tea. beer, wine and liquor. Some societies prefer their beverage to be warm. In any event, there is a need for providing the consumer of the beverage with information regarding beverage temperature prior to consuming the beverage.

In addition, consumers prefer that their beverage maintain their desired temperature over the time the beverage in the container is completely consumed.

At the present time, a wide variety of temperature insulation retainers for retaining a beverage container include fixed retainers and flexible retainers. Included in such retainers are collapsible retainers which, when the beverage container is removed therefrom can be compressed and carried in a pocket. This permits the retainer user to utilize it as the consumer travels over time.

U.S. Pat. No. 5,645,196 discloses a retainer for a beverage carton such as for juice or milk. The retainer can include a thermometer that measures the temperature for the beverage in the carton. In order to view the thermometer, the retainer must be transparent. No collapsible beverage containers are disclosed.

U.S. Pat. No. 5,482,373 discloses a temperature indicator for a beverage container. The temperature indicator can be applied directly to the container or can be positioned frictionally into the wall of an insulating retainer that retains the beverage container. The wall of the beverage retainer must be sufficiently inflexible as to retain the thermometer in place by friction forces. No collapsible beverage retainers are disclosed.

Accordingly, it would be desirable to provide a collapsible insulating beverage retainer with a means for measuring temperature, such as a thermometer in a beverage container. Such a retainer would provide the beverage consumer with desired temperature information and ease of portability. In addition, such a retainer would provide ease of securing the temperature sensing means to the retainer by first securing it to an outside surface of the retainer thereby providing easy access to the retainer surface to which it is secured. The retainer then could be turned inside out so that the temperature sensing means would be adjacent to or in contact with the beverage container during use.

SUMMARY OF THE INVENTION

In accordance with this invention, a retainer formed of a thermal insulating material for a beverage container is provided. The retainer includes a temperature sensing means, such as a thermometer which is positioned on the retainer at a position such that it can measure the temperature on the outside surface of the beverage container. The retainer has a top wall surface surrounding an open top surface and a bottom wall surface surrounding an open bottom such that it can be turned inside out when desired. The wall tapers from the open top toward the open bottom. This permits the temperature sensing means to be initially secured to an easily accessible outside surface of the retainer. The retainer then can be turned inside out so that the secured temperature sensing means is positioned on a newly formed inside surface of the retainer adjacent to or in contact with the beverage container positioned in the retainer. The temperature sensing means is attached peripherally by stitching it directly to the retainer or stitching a web to the retainer which holds the temperature sensing means on the retainer.

DESCRIPTION OF SPECIFIC EMBODIMENTS

The retainer of this invention having a temperature sensing means attached thereto is configured to retain a beverage container having a tapered wall such as a hot beverage container for coffee or tea. The retainer is formed of a material and is configured so that it can be turned inside out prior to use. The temperature sensing means is secured to a wall of the retainer such as by stitching. The temperature sensing means can be directly attached to the retainer or can be held in place by a retaining wall that is directly attached, such as by stitching to the retainer. The temperature sensing means, such as a conventional liquid crystal temperature indicating material is preferably positioned adjacent to or in contact with the beverage container. When the temperature sensing means initially is attached to or retained in an outside surface of the retainer, it is preferred to turn the retainer inside out to thereby position the temperature sensing means as close as possible to the beverage container so as to provide more accurate temperature measurement. When the temperature sensing means is in position to be viewed by the user, and a retaining web is interposed between the user and the temperature sensing means, the retaining web must be transparent, or at worse, translucent to permit the user to view the temperature sensing means. For ease of producing the retainer of this invention, it is preferred to secure the temperature sensing means to an initial outside surface of the retainer and then turning the retainer inside out. Although more difficult, it is possible to secure the temperature sensing means to an initial inner surface of the retainer.

Referring to FIGS. 1 and 2, the retainer 10 comprises a tapered wall 12, having a top edge 14 and a bottom edge 16. The wall 12 is formed of single ply or multi ply flexible and/or expandable thermally insulating material. The openings surrounded by edges 14 and 16 permit the retainer 10 to be compressed relatively flat so that it can be carried in a pocket. The temperature sensing means 18 includes liquid crystal displays (LCD) 20 that light up by being temperature activated and can show any indicia such as a number or a word display indicative of the temperature. The group of LCDs 20 can display a series of temperatures indicative of the degree of coolness or warmth of the beverage container. The temperature sensing means 18 is secured to the wall 12 by retaining wall 22 and stitching 23. After the stitching 23 has been completed, the wall 12 is turned inside out so that the temperature sensing means 18 is closer to the beverage container 24. (FIG. 7).

As shown in FIG. 2, the temperature sensing means 18 is positioned against the wall 12 by retaining wall 22. When retaining wall 22 is finally positioned on the outside surface of wall 12, it must be transparent or translucent to permit viewing of the LCDs 20. When the LCDs 20 are finally positioned against opening 26 on an outside surface of wall 12, the retaining wall 22 need not be transparent or translucent to permit viewing the LCDs 20 by the user.

Referring to FIGS. 3 and 4, the retainer 30 comprises a wall 12 having a temperature sensing means 18 that includes liquid crystal displays (LCD) 20. The temperature sensing means 20 is secured directly to wall 12 by stitching 28. After the stitching 28 has been completed, the retainer 30 is turned inside out so that the temperature sensing means 18 is closer to the beverage container 24. (FIG. 7)

As shown in FIG. 4, the temperature sensing means 18 is stitched directly to the wall 12.

Referring to FIGS. 5 and 6, the retainer 32 comprises a wall 12, having a temperature sensing means 18 including liquid crystal displays (LCD) 20. The temperature sensing means 20 is secured to wall 12 by retaining wall 27 and stitching 31. Due to slots 33, the wall need not be turned inside out since the temperature sensing means 20 is initially closer to the beverage container.

As shown in FIG. 6, the temperature sensing means 18 is positioned against the wall 12 by retaining wall 27. The slot 33 permits direct air convection between a beverage container within wall 12 and temperature sensing means 18.

Referring to FIG. 7, in use, a beverage container 24 fits into wall 12 against temperature sensing means 18.

Referring to FIGS. 8 and 9, the beverage container section 10 is formed by stitching 34 to form openings 36 and 38.

Referring to FIG. 10, the wall 12 can comprise a three ply structure wherein the outer plies 37 and 39 are formed of a stretchable, flexible fabric and the inner ply 41 comprises a thermally insulating foam.
