Description
Background of the Invention
The present invention relates to portable insulated vessels for holding, transporting and maintaining liquids at stable temperatures.
Portable insulated vessels for holding and maintaining, for a period of time, liquids at stable temperatures, which are the temperatures of the liquids when introduced to the containers, are represented by conventional, so-called, vacuum bottles. Such vacuum bottles are so made that only one liquid may be carried therein at one time. However, the prior art, so far as known discloses in U.S. Pat. No. 124,465 a single container wherein water and beer are carried in separate containers in such a way that the liquids are separable by means of stop cocks inserted at the proper places in the vessels.
It is noted though that only liquids that are to be cooled or maintained at a temperature colder than ambient can be carried in the device of U.S. Pat. No. 124,465.
Those skilled in the art will recognize, however, from the following description of one embodiment of the invention, and from the drawing thereof, that a plurality of liquids may be carried in the device of the present invention and that the liquids of the present invention may be of different temperatures or the same temperature.
Thus, the liquid container of the present invention has a number of significant features and advantages over the known prior art that will become evident to those skilled in the art from the following description of the embodiment described and shown hereinafter.
Summary of the Invention
A liquid container comprises an outer vessel within which are a plurality of individual liquid containers or vessels for holding various liquids. Insulation means is disposed between the individual inner vessels and the inner walls of the outer vessel. Means is provided for filling each individual inner vessel with liquid, and means is provided for pouring liquid out of each individual inner vessel. Means is provided for closing each filling means and each pouring-out means, and means for carrying the liquid container is provided.
For a further description and understanding of the invention, and for features and advantages thereof, reference may be made to the following description of one embodiment of the invention and a drawing thereof.

FIG. 1 is a schematic view, as a vertical cross section, of an insulated liquid container in accordance with one embodiment of the invention;
FIG. 2 is a view along line II--II of FIG. 1, and
FIG. 3 is a view along line III--III of FIG. 1 showing the top of the container.
Detailed Description
Referring to FIG. 1, an insulated liquid container 11, in accordance with the present invention, comprises a large outer vessel 13 made of suitable plastic material or thin metal, within which there are a plurality of separate, individual liquid containers or vessels. First and second inner vessels 15, 17 each has an arcuate wall 15b, 17b, that is connected to flat wall portions 15a, 17a that merge, as shown, with wall 29 of the third inner vessel 27. The vertical walls of the first, second and third inner vessels 15, 17 and 27 connect to a common bottom 26. The first and second inner vessels 15, 17 have each a horizontal top, as shown.
The walls of the inner vessels 15, 17, 27 may be made of suitable thin plastic material or stainless steel, as an alternative metalic material.
The inner vessels 15, 17 are spaced apart from each other and from inner wall 19, top 23, and bottom 25 of the large outer container 13. The spaces between the inner vessels 15, 17, 27 and the inner surface of the outer vessel 13 are filled with a suitable insulating material 21 such as Styrofoam, or the like. Likewise, the spaces between the inner vessels themselves are filled with the same thermal insulating material 21.
Concentrically located within the large outer vessel 13 is a cylindrical liquid container or vessel 27 that may be made of the same material as the other inner vessels 15, 17. The third inner vessel 27 has an extension 30 that protrudes through the top 23, and the outer top portion 31 of the vessel 27 is threaded to receive a screw cap closure 33.
The first and second inner vessels 15, 17, each has a vertical fill pipe 43, 45 that is suitably closed by a screw cap 47. Each fill pipe 43, 45 may, of course, be closed by a plug insert if desired or in any other preferred manner.
Each inner vessel 15, 17, 27 is spaced from the bottom 25, and the three inner vessels are supported thereon by a vertical wall 28.
The inner vessels 15, 17 each has a pouring-out spout 35, 37 respectively that is angularly disposed from the top corner of each vessel 15, 17 as shown in FIG. 1. Each pouring-out spout is provided with a closure 39, 41 respectively that may be a screw cap like that shown or a plug-in closure if desired.
A conventional type of bail 49 is pivotally attached to the outer container 13, as at 51, for the purpose of carrying the liquid container 13.
In use the inner containers or vessels 15, 17 may carry either hot or cold liquids that will remain at the incipient temperature since the inner vessels are well insulated from the ambient temperature.
When a hot liquid is carried in one container, say 15, and a cold liquid is carried in another container, say 17, the cylindrical container 27 would remain empty and acts as an air space between containers carrying liquids at different temperatures.
In some instances, both the inner vessels 15, 17 may contain cold liquids, and in such instances, the cylindrical container 27 may hold ice or the like to maintain the liquids cold.
If both the inner vessels 15, 17 hold hot liquids, the cylindrical inner vessel 27 may also hold a hot liquid. Each hot liquid may be different from another. As an example, hot coffee may be contained in vessel 15; hot tea in vessel 17; and hot cocoa in vessel 27.
From the foregoing description of the one embodiment of the invention and the drawing thereof set forth herein, those skilled in the art will recognize several features and advantages thereof among which the following are noted:
That two or three distinct liquids may be carried simultaneously in the container of the invention;
That the container is both simple to construct and is easily carried from place to place;
That it is efficient in keeping liquids at incipient temperatures;
That the contained liquids can be easily dispensed;
That three or more inner vessels may be disposed in the outer container whereby different liquids may be carried therein;
That the individual inner vessels may contain either hot or cold liquids in each vessel, or hot and cold liquids in different vessels therein; and
That the individual inner containers may hold cold liquids that are maintained at incipient temperature by a cold substance in the third inner vessel.
Whereas, the invention has been described in relation to one embodiment thereof, it is understood that other modifications may be made therein without departing from the spirit thereof and the scope of the appended claims.
