Application October 19, 1945, Serial No. 623,380

4 Claims. (01. 65-13) The present invention relates to a novel construc'tion'ior liquid containers or devices assoraised from a. surface.

Particularly in the case of'containers used for cold liquids, iced. drinks, etc., the formation of condensed moisture on the exterior surface of the container presents a problem which up to the present time has not been satisfactorily solved. This problem is more particularly acute in the summertime when the humidity of the atmosphere is uniformly higher and the consumption of cold and iced drinks is more widespread.

As will be apparent from the following specification when considered in connection with the accompanying drawings, the basic inventive idea herein disclosed is susceptible of use in connection with a wide variety of receptacles of the type normally used for serving cold or iced drinks.

In the drawings,

Figure l is a side elevational view of a conventional drinking glass or tumbler having associated therewith a coaster embodying the improvements of the present invention, the coaster being illustrated in section in order to illustrate the improvements of the present invention.

Figure 2 is a bottom plan view of the improved coaster construction shown in Figure 1. it

Figure 3 is aside elevational view of a conventional beverage bottle embodying the im-- provements of the present invention, the bottom portion thereof being illustrated in section to show the improvements of the present invention.

Figure 4 is a vertical sectional view through a drinking glass embodying the improvements of the present invention.

With more particular reference to the drawings, it will be seen that in all embodiments of the invention, it is contemplated that a capillary groove or channel be provided in the base portion of the receptacle and it has been found that when the glass or bottle is raised from a surface, even a wet surface, the-accumulated moisture will accumulate in the capillary groove instead of dripping from the receptacle-while in elevated position.

'In the construction shown in Figure 1 of the drawings, a conventional drinking glass I has associated therewith a coaster or separable base portion 2 which, although detachable from the glass I, is preferably constructed in such away as to remain in assembled relation with respect to the glass during use. "This coaster :is preferably formed with an annular, upwardly extending flange 3 serving to provide a recess into which the base portion of the glasswillfit snugly enough to retain the glass. and coaster in assembled relation during normal use.

The underside of the coaster 2 comprises mainlypa fiat, plain surfacel which may ormay not be"relieved by a central depression 5/ Spaced inwardly from themarginal edge of the bottom ofl'the coaster is formed an annular groove or recess 6 which by means of capillary attraction will serve to accumulate the condensed moisture which would normally drip from the glass when the same was raised from a supporting surface.

ilWhile the particular material of which the coaster may be formed does not constitute a part ofi-the present invention, it has been found that particularly superior results can be obtained by forming the coaster by injection molding from any one of a wide variety of well known plastic materials. This form of construction is advantageous because it is not only economical for large scale production, but because it inherently results in an accurate product.

frIt is of great importance that the intersection of the bottom surface of the coaster with the side walls of the channel 5 provide a precise and sharp corner and, further, that the side walls of the roove 6 be substantially parallel in order to obtain the maximum capillary effect. Injection molded plastics readily lend themselves to such ai 'construction and make possible the provision of' an accurate and precise article without the necessity of subsequent finishing operations.

As is seen in Figure 3 of the drawings, a conventional beverage bottle may easily be modified tdjincorporate' the improvements of the present invention. In this embodiment, the bottle I is provided with a relatively thick, heavy base portion 8 near the outer edge of which is formed a c illary groove or channel 9 similar in form, c nstruction, and function to the channel 8 described above in connection with the preferred embodiment of the invention.

In Figure 4 is shown a tumbler which may be formed either of glass or plastic material. This tumbler I is likewise provided with a relatively heavy, thick bottom wall II which has formed therein a capillary groove [2 which serves the same purpose as the capillary grooves or channels 6 and 9 described above.

While the precise dimensions of the channels 6, 9, and I2 are not critical, it has generally been found that'mos'tsatisfactory" results will be obtained if these channels are at least as deep as they are wide and that satisfactory capillary action will be obtained if the width of the channel ranges from one-sixteenthtonearly three-sixteenths of an inch.

Many other and further modifications of the invention falling within the scope thereof, as set forth in the following claims, will become apparent to those skilled in the art.

What is claimed is:

1. Areceptacle for. iced or cold beverages, said receptacle having side walls and a base portion having formed therein an annular capillary groove, the intersections of the Side walls of said groove with the bottom surfaceof said receptacle forming a relatively sharp corner.

Q12. ALcfoaster for association. with" a; drinking glass, comprising a cup-shaped,fupper 'portion adaptedto receive a drinking. glassf therein, and a base, portion having formed therein an annular capillary. groove, the intersections of the side walls of said groove with the bottom surface of said coaster'm'ember forming a relatively sharp corner.

, 3. A drinking'l' glass for iced or cold beverages having walls andfa base portion, said basehav ing in its undensurfaQe'an. annular capillary groove, the intersections of the side walls of said groove with the said under surface of said base portion forming a relatively sharp corner.

4. A bottle or similar container for iced 01' cold REFERENCES CITED The following references are of record in the file of this patent:
