Claims.

,This invention relates to an improvement in cocktail shakers.

One of the principal objects of the present invention is to provide a cocktail shaker which is designed for the thorough and expeditious mixbalanced and easily handled, readily and effectively sealed or opened up to dispense a drink, and yet of simple and durable construction and capable of being economically produced by manufacturing facilities and from materials readily available.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being bad to the accompanying drawing, forming a part of this specification, and in which:

Figure 1 is a view partly in side elevation and partly in transverse vertical section showing a cocktail shaker embodying the present invention;

Figure 2 is a view in horizontal section taken on line 2-2 of Figure 1; and

Figure 3 is a View in plan of the lower end cap, the same being viewed from line 3-3 of Figure 2 but the body or shell of the shaker being omitted.

Referring to the drawing, and more particularly to Figure 1, the numeral I designates generally the body or shell of the shaker which preferably consists of a drawn metal shell, the shell being drawn from a sheet of copper or other suitable metal and being suitably plated, as, for example, chromium plated. The body portion of the shell has an integral body 2 and at its upper end has a reduced neck 3 which is internally threaded as at 4 and provided with an outturned terminal flange 5.

For the base of the shaker a lower end cap designated at 6 is provided and preferably is molded from bakelite or other suitable composition. The end cap 6 has a flat bottom plate I and an annular peripheral flange 8 which partially telescopes over the lower end of the body of the shaker. Bosses 9 are integrally formed with the interior of the base I of the lower end cap and are apertured to permit of the use of the screws iii countersunk in the cap 6 and threaded into nuts I! welded or soldered to the bottom 2 of the body of the shaker. A removable upper end cap I5 is provided and 5 is also molded from bakelite or other suitable composition. The properties that are essential in the composition are that caps 6 and !5 be sufliciently strong and rigid and also capable of resisting or retarding the exchange of heat, that 10 is, the material of which these caps are composed must be of low heat conductivity. The body portion [6 of the upper end cap [5 has an outer peripheral outer flange 11. It also has a central opening [8 and around the margin of this opening 98 an integral upwardly extending annular flange 28 is provided. Likewise around the margin of its opening IS a downwardly extending marginal flange 2| is formed. Between Opposed portions of this flange 2| a number of spaced grids or bars 22 extend and are molded integral with the flange 2| to provide a strainer. In addition to the flange 2|, a third flange 23 is integrally molded with the upper cap l5 and is located just outside of the flange 2| and in 25 spaced relation to the flange IT. The exterior of this flange 23 is formed with threads 24 of a formation corresponding to the threads 4 and interengageable therewith in the assembly to mechanically and releasably interconnect the upper end cap and the shell or body portion of the shaker. In the space between the flanges 23 and I! and above the threads 24, a washer or gasket 25 is provided and when the upper cap I5 is in place this washer is compressed against the flange 5 to provide an effective seal.

A closure 39 is provided for the opening I! and preferably is in the form of an inverted cup to which an ornamental handle or finger piece 3] is attached. The body of the cup 38 is tapered in 40 a manner corresponding to the tapered formation of the opening I7 and of the interior surface of the flange 20. Further, as the exterior surface of the body of the cup 38 and the surface of opening 98 and of flange 28 are smooth, when the cup 3b is in the position shown in Figure 1, these surfaces are snugly and frictionally engaged to hold the parts together and also to provide a seal therebetween.

When the closure 30 is removed it may be turned over to provide a jigger for measuring the amount of the alcoholic base of the drink.

In mixing a drink, the upper cap I 5 is first removed and the ingredients placed in the body portion of the shaker, the closure 30 being utilized if desired and, as pointed out, for the purpose of measuring the amount of alcoholic or flavoring ingredients. The closure 3!! may then be put in the position shown in Figure 1 and the end cap screwed into place. The operator then grasps the end cups, placing his fingers over the part 3i of the closure 38 and shakes the entire device up and down until the contents have been appropriately agitated and chilled. The metal shell or body or" the shaker will sweat and give the cold appetizing appearance that is desired but the drink mixer will not have his hands chilled since they are protected by the insulated end caps. When the shaking has been completed the closure is removed and the drinks poured directly into the cocktail glasses.

While I have shown and described one construction in which the invention may be advantageously embodied, it is to be understood that this construction has been selected merely for the purpose or" illustration or example and that various changes in the size, shape and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subioined claims.

The invention claimed is:

1. A device of the character described comprising a shell-like metallic container and caps of insulating material associated with the ends of the container and designed to be grasp-ed by the hands, one of said end caps being removable and having an opening therein provided with a strainer, and a removable closure for said opening.

2. A device of the character described comprising a cylindrical metal container having a closed bottom and provided with a reduced neck at its upper end, said neck defining an opening into the container, a bottom end cap of flanged formation fitted over the bottom of the container and secured thereto, and a removable top cap adapted to be interthreaded with the neck, said caps being of insulating material so that iced drinks may be mixed and agitated without chilling the hands.

3. A device of the character described comprising a cylindrical metal container having a closed bottom and provided with a reduced neck at its upper end, said neck defining an opening into the container, a bottom end cap of flanged formation fitted over the bottom of the container and secured thereto, a removable top cap adapted to be interthreaded with the neck, said caps being of insulating material so that iced drinks may be mixed and agitated Without chilling the hands, said top cap having an opening, and a removable closure for said opening.

4. A device of the character described comprising a cylindrical metal container having a closed bottom and provided with a reduced neck at its upper end, said neck defining an opening into the container, a bottom end cap of flanged formation fitted over the bottom of the container and secured thereto, and a removable top cap adapted to be inter-threaded with the neck, said caps being of insulating material so that iced drinks be mixed and agitated without chillthe hands, said neck having a flanged seat, said cap having a recess provided with a gasket engageable with said flanged seat when the cap is applied.

5. A cocktail shaker comprising a shell-like metallic container and end caps fitted over the ends the hand, said caps being of insulating material so that iced drinks may be mixed and agitated without chilling the hands, one of said caps being removable.
